What are the components of a fully automatic injection molding machine?

writer:LI SONG Share

Fully automatic injection molding machine is usually composed of electrical control system, hydraulic drive system, mold clamping system, injection system, heating and cooling system and other parts. Let's introduce these components.

1. The electrical control system of the fully automatic injection molding machine
The electrical control system and hydraulic system are reasonably coordinated to achieve various program actions (pressure, temperature, speed, time) required by the process of the fully automatic injection molding machine. It is mainly composed of electrical appliances, electronic components, meters, heaters, sensors, etc. There are usually four control modes, manual, semi-automatic, fully automatic and adjustment.

2. Hydraulic transmission system of fully automatic injection molding machine
The function of the hydraulic transmission system is to provide power for the various actions of the automatic injection molding machine according to the process, and to meet the pressure, speed, temperature and other requirements of the various parts of the automatic machine. It is mainly composed of various hydraulic components and hydraulic auxiliary components, among which the oil pump and the electric motor are the power source of the automatic injection molding machine.

3. The clamping system of the automatic injection molding machine
The function of the clamping system is to ensure that the mold is closed, opened and ejected. At the same time, after the mold is closed, sufficient clamping force is provided to the mold to resist the cavity pressure generated by the molten plastic entering the mold cavity, and to prevent the mold from opening the joints, resulting in a bad state of the mold. The composition of the automatic injection molding machine mold clamping system is mainly composed of a mold clamping device, a mold clamping mechanism, an ejection mechanism, a front and rear fixed template, a movable template, a mold clamping cylinder and a safety protection mechanism.

4. Injection system of fully automatic injection molding machine
The injection system is one of the important components of a fully automatic injection molding machine. There are usually three types: plunger type, screw type and screw pre-plastic plunger injection type. The screw type is currently widely used. Its function is to heat and plasticize a certain amount of plastic within a specified time in a cycle of the fully automatic injection molding machine, and to inject molten plastic into the mold cavity through a screw under a certain pressure and speed.

5. Heating/cooling system of automatic injection molding machine
The heating system is used to heat the barrel and nozzle. The barrel of a fully automatic injection molding machine usually uses an electric heating ring as a heating device. The heating ring is installed on the outside of the barrel and is inspected in sections by thermocouples. The heat conducts heat through the cylinder wall, thereby providing a heat source for the plasticization of the material. The cooling system is mainly used to cool the oil temperature. Excessive oil temperature can cause various failures, so oil temperature must be controlled. Another location that needs to be cooled is near the feed port of the feed pipe to prevent the raw material from melting at the feed port, causing the raw material to fail to feed normally.
