1. Overview

Injection machine, also known as injection molding machine. It is the thermoplastic or thermosetting plastic plastic molding mold made of various shapes of plastic products, the main molding equipment. Divided into vertical, horizontal, all-electric. Injection molding machine can be heated plastic, the molten plastic to exert high pressure, so that injection and full of mold cavity.

2. Structure function

2.1 Introduction

Injection molding machine is usually composed of injection system, mold clamping system, hydraulic transmission system, electrical control system, lubrication system, heating and cooling system, safety monitoring system and so on.

2.2 injection system

The role of injection system: injection system is one of the most important components of injection molding machine, generally have plunger, screw, screw pre-plastic plunger injection of three major forms.

The most widely used is the screw type. Its role is that in a cycle of injection molding machine, in a specified period of time will be a certain amount of plastic heating plastic, at a certain pressure and speed, through the screw will melt plastic into the mold cavity. At the end of the injection, the melt injected into the mold cavity is held in shape.

The composition of the injection system: The injection system consists of a plasticizing device and a power transmission device.

Screw injection molding machine plasticizer mainly by the feeding device, barrel, screw, glue components, nozzle part of the composition. The power transmission device includes an injection cylinder, an injection seat movement cylinder, and a screw drive device (melt pump).

2.3 mold clamping system

The role of mold clamping system: the role of mold clamping system is to ensure that the mold closed, open and eject products. At the same time, after the mold is closed, the mold is supplied with sufficient clamping force to resist the mold cavity pressure generated by the molten plastic into the cavity to prevent the mold from opening, resulting in poor product status.

The clamping system consists of clamping device, machine twist, mold adjustment mechanism, ejector mechanism, front and rear fixed template, moving template, mold clamping cylinder and safety protection mechanism.

2.4 Hydraulic system

The role of hydraulic transmission system is to achieve the injection molding machine according to the process required to provide a variety of action power, and to meet the various parts of the injection molding machine required pressure, speed, temperature and other requirements. It is mainly composed of various hydraulic components and hydraulic auxiliary components, including oil pump and motor is the power source of injection molding machine. Various valves control the oil pressure and flow, thus meeting the requirements of the injection molding process.

2.5 Electrical control

Electrical control system and hydraulic system with a reasonable, can achieve the injection process requirements (pressure, temperature, speed, time) and a variety of program action. Mainly by the electrical, electronic components, instruments, heaters, sensors and other components.

There are four general control methods, manual, semi-automatic, fully automatic, adjusted.

2.6 Heating / cooling

Heating system is used to heat the barrel and injection nozzle, injection molding machine barrel generally used as a heating device heating device, installed in the barrel of the external, and thermocouple segment detection. Heat through the cylinder wall heat transfer material for the material to provide heat; cooling system is mainly used to cool the oil temperature, the oil temperature is too high will cause a variety of failures so the oil temperature must be controlled. Another place to be cooled in the vicinity of the material pipe discharge, to prevent the raw material in the feed port melting, resulting in raw materials can not be properly cut.

2.7 lubrication system

Lubrication system is the dynamic movement of the injection molding machine, the mold clamping device, the connecting rod hinge, the shooting table and so on have the relative movement part to provide the lubrication condition the circuit in order to reduce the energy consumption and improve the life of the parts, the lubrication may be the regular manual lubrication, It can be automatic electric lubrication;

2.8 Safety monitoring

The safety device of the injection molding machine is mainly used to protect the human and machine safety devices. Mainly by the security door, safety baffle, hydraulic valve, limit switch, photoelectric detection components, etc., to achieve electrical – mechanical – hydraulic interlock protection.
Monitoring system mainly on the injection molding machine oil temperature, temperature, system overload, as well as process and equipment failure to monitor and find abnormal conditions to indicate or alarm.

3. working principle

The working principle of the injection molding machine is similar to that of the injector, which is the injection of the plasticized molten state (ie, viscous) into the closed cavity by means of the thrust of the screw (or plunger) The process of obtaining the finished product after curing.

Injection molding is a cycle of the process, each cycle mainly include: quantitative feeding – melt plasticization – pressure injection – charge cooling – picking. Remove the plastic parts and then closed the mold, the next cycle.

Injection molding machine operation project: injection molding machine operation project includes control keyboard operation, electrical control system operation and hydraulic system operation three aspects. Respectively, the injection process action, feeding action, injection pressure, injection speed, the choice of the top type, barrel temperature monitoring, injection pressure and back pressure pressure adjustment.

There are three main aspects of the evaluation of plastic products, the first is the appearance of quality, including integrity, color, gloss, etc .; the second is the size and relative position between the accuracy; the third is the physical properties associated with the use of chemical properties, Electrical performance and so on. These quality requirements and according to the use of different products, the required scale is also different. The defects of the products mainly lie in the design, manufacturing precision and wear degree of the molds.The adjustment of the process in the production process is the necessary way to improve the product quality and production. As the injection cycle itself is very short, if the process conditions are not good, waste will be endless. In the adjustment process, the best time to change only one condition, more observation a few times, if the pressure, temperature, time all together with the tune, it is easy to cause confusion and misunderstanding, a problem do not know what reason.

4. Energy saving

Injection molding machine energy can be divided into two parts: one is the power part, one is the heating part.

Power part of the energy: most of the inverter, energy-saving way is to save the motor by the excess energy, such as the actual power of the motor is 50Hz, and you actually only need 30Hz production in the production, and those excess energy consumption in vain Wasted, the inverter is to change the power output of the motor to achieve energy saving effect.

Heating part of the energy: heating part of the energy-saving mostly use electromagnetic heaters, energy-saving rate is about 30% -70% of the old resistance ring.

1, compared to resistance heating, electromagnetic heater more than a layer of insulation layer, heat utilization increased.
2, compared to resistance heating, electromagnetic heater directly on the tube heating, reducing the heat transfer heat loss.
3, compared to resistance heating, electromagnetic heater heating speed faster than a quarter, reducing the heating time.
4, compared to resistance heating, electromagnetic heater heating speed, production efficiency is improved, so that the motor is saturated, so that it reduces the high power demand caused by low power consumption.

5. Classification

8. Operation points

8.1 Before powering on

1, before the injection molding machine operation, check the electrical control box whether there is water, oil into, if the electrical damp, do not boot. There should be maintenance personnel to dry the electrical parts and then boot.

2, before the injection molding machine operation, check the supply voltage is consistent, generally should not exceed ± 6%.

3, check the emergency stop switch, before and after the safety door switch is normal. Verify that the direction of rotation of the motor and the pump is the same.

9. Precautions

9.1 Hazard

Injection molding machine temperature rise is too high five hazards: the machine heat distortion, oil viscosity decreases, rubber seals deformation, accelerated oil oxidation deterioration, but also to reduce the sub-pressure of the air.

One of the hazards: the machine heat distortion
Hydraulic components in the thermal expansion coefficient of different moving parts because of its small gap with the stuck, causing malfunctions, affecting the hydraulic system transmission accuracy, resulting in deterioration of the quality of work components.

Hazard of the second: the viscosity of the oil reduced
High temperature rise of the injection molding machine will lead to lower viscosity of the oil, increased leakage, pump volumetric efficiency and the efficiency of the entire system will be significantly reduced. As the viscosity of the oil decreases, the oil film of the moving parts such as the slide valve becomes thinner and cut, and the frictional resistance increases, resulting in increased wear.

Damage to the three: the rubber seal deformation
Injection molding machine temperature rise is too high will make rubber seals deformation, accelerated aging failure, reduce the sealing performance and service life, resulting in leakage.

Hazard of the four: to accelerate the deterioration of oil oxidation
Injection molding machine temperature rise is too high will accelerate the deterioration of oil oxidation, precipitation of asphalt material, reduce the life of hydraulic oil. Precipitates clog the damp hole and the slotted valve port, causing the pressure valve to stuck and not move, the metal pipe is elongated and bent, or even broken.

Hazard of five: lead to deterioration of the quality of work components
Injection molding machine temperature rise is too high will lead to deterioration of the quality of work components, oil dissolved in the air escape, resulting in cavitation, resulting in reduced hydraulic system performance. The ideal operating temperature of the hydraulic system should be between 45 ° and 50 °, because the hydraulic system is designed to vary depending on the viscosity of a selected pressure oil, but the viscosity will vary with the oil temperature, which in turn affects the work in the system Components such as cylinders, hydraulic valves, etc., to reduce the control accuracy and response sensitivity, especially for the precision injection machine. While the temperature is too high will accelerate the aging of the seal to harden, fragmentation; temperature is too low processing energy consumption, so that the operating speed. So pay close attention to the working temperature of hydraulic oil is very necessary. Oil temperature is too high for a variety of reasons, but more due to oil failure or failure of the cooling system.

9.2 Handling methods

(1) according to different load requirements, often check, adjust the relief valve pressure, so that just right.

(2) a reasonable choice of hydraulic oil, especially oil viscosity, in conditions permitting, try to use a little lower viscosity to reduce the viscosity of friction loss.

(3) to improve the lubrication of sports parts to reduce the friction loss, help reduce the workload and reduce heat.

(4) to improve the hydraulic components and hydraulic system assembly quality and their own accuracy, and strictly control the fit with the gap and improve the lubrication conditions. The use of a small coefficient of friction sealing material and improve the sealing structure, as far as possible to reduce the power of the hydraulic cylinder to reduce the mechanical friction caused by the loss of heat.

(5) If necessary, add a cooling device.

9.3 Selection

In general, in the injection industry for many years the majority of customers have the ability to judge and choose the appropriate injection molding machine to produce. But in some cases, the customer may need the help of the manufacturer to decide which one of the specifications of the injection molding machine, and even the customer may only sample or concept of the product, and then ask the manufacturer’s machine can produce, or which model comparison Suitable for.

In addition, some special products may need to be equipped with special devices such as accumulators, closed circuits, injection compression, etc., in order to more efficient production.

The important factors that usually affect the selection of the injection machine include mold, product, plastic, molding requirements, etc., so you must collect or have the following information before making your selection:

Mold size (width, height, thickness), weight, special design;

Use the type and quantity of plastic (single raw material or a variety of plastic);

The appearance of the finished product (length, width, height, thickness), weight, etc .; molding requirements, such as quality conditions, production speed.

Once you have obtained the above information, you can follow the steps below to select the appropriate injection machine:

1, determined by the product and plastic models and series.
As the injection machine has a very large number of types, so the beginning of the first to determine whether the product should be a kind of injection molding machine, or which series to produce, for example, is the general thermoplastic or bakelite raw materials or PET raw materials, Color, two-color, multi-color, sandwich or mixed color. In addition, some products require high stability (closed loop), high precision, high speed, high pressure or rapid production (multi-loop) and other conditions, must also choose the appropriate series to produce.

2, by the mold size to determine the machine’s “big column within the distance”, “die thickness”, “mold minimum size” and “die size” is appropriate to confirm whether the mold is released.
The width and height of the mold need to be less than or at least one side is smaller than the large column distance;
The width and height of the mold are preferably within the die size range;
The thickness of the mold should be between the die thickness of the injection molding machine;
The width and height of the mold must meet the minimum mold size recommended by the injection molding machine, too small to do;

3, by the mold and finished products to determine the “open stroke” and “care stroke” is enough to remove the finished product.
The stroke of the mold must be at least twice the height of the finished product in the direction of the switch mold and the length of the sprue is required; the stroke of the mold must be sufficient to eject the finished product;

4, by the product and plastic decision “clamping force” tons.
When the raw material into the mold cavity with a high pressure will produce a support force, so the injection molding machine module must provide sufficient “clamping force” so that the mold will not be distracted.

At this point, the size of the mold clamping unit has been initially determined and the tonnage of the mold is roughly determined. The following steps must be carried out to confirm which screw diameter of the injection unit is more suitable.

5, by the finished product weight and the number of points to determine the required “injection” and select the appropriate “screw diameter.”
Calculate the weight of the finished product to consider the number of mold points (a mold points);

6, determined by the plastic “screw compression ratio” and “injection pressure” and other conditions.
Some engineering plastics need a higher injection pressure and the appropriate screw compression ratio design, have a better molding effect, so in order to make the finished product shot better in the choice of screw also need to consider the need for pressure and compression ratio of the problem The
In general, a smaller diameter screw can provide a higher injection pressure.

7, “injection speed” to confirm.
In some cases, it may be necessary to confirm whether the machine’s injection rate and firing rate are sufficient, whether it is necessary to match the accumulator, closed circuit control and other devices. In general, under the same conditions, can provide a higher jet pressure of the screw is usually low firing rate, on the contrary, can provide a lower jet pressure of the screw is usually higher speed. Therefore, when the screw diameter is selected, the injection amount, the injection pressure and the injection rate (injection speed) are required to be cross-considered and selected.

In addition, multi-loop design can also be used to shorten the molding time by simultaneous compound action.

After the above steps, in principle, has been able to determine the needs of the injection molding machine.

In any case the security facility should not be disconnected from the machine or does not work. If you really need to remove the safety device to service the machine, you must ensure safety. After the repair work is completed, return the safety equipment and check the effect as is.

9.6 failure

1, according to the state of failure, can be divided into:

(1) Gradual failure. Is due to the initial performance of the injection molding machine is gradually deteriorated, most of the injection molding machine failure are such failures. This type of fault and electronic control, hydraulic mechanical parts wear, corrosion, fatigue and creep processes are closely related.

(2) sudden failure. Is a variety of unfavorable factors and the occasional external effects arising from the joint effect, this effect beyond the injection molding machine can withstand the limits. For example: due to the barrel into the iron overload caused by the screw broken; due to high voltage string into the breakdown of the injection molding machine electronic board. Such failures are often sudden, without any prior signs.

Sudden failure occurred in the use of injection molding machine stage, often due to the design, manufacture, assembly and material defects, or operational errors, illegal operations caused.
