The operating principle and components of plastic injection molding machine

Plastic injection molding machines are mainly composed of the following parts:

1. Injection molding system: including feed, screw, heating cylinder, storage hopper, injection cylinder and other components. The plastic particles are fed into the screw through the feeding mechanism, the screw melts the plastic, and pushes the molten plastic into the injection cylinder, and finally the molten plastic is injected into the mold through high pressure.

2. Clamping system: mainly composed of template, mold, clamping mechanism, mold opening mechanism, etc. The template is pressed by the clamping system to close the mold, and then the molten plastic is injected for injection molding.

3. Hydraulic system: mainly composed of hydraulic pump, oil tank, motor, hydraulic valve, pressure gauge, etc. The function of the hydraulic system is to provide the required high pressure and flow, drive the opening and closing, lifting and locking of the injection cylinder and mold.

4. Control system: mainly composed of electrical controller, program controller, operation panel, sensor, etc. The operation of the entire injection molding machine is controlled by the electrical controller and program controller, such as adjusting parameters such as injection speed, pressure and temperature to ensure product quality and production efficiency.

This is the end of the content shared by the injection molding machine manufacturer about "The operating principle and components of plastic injection molding machines". The operating principle and components of plastic injection molding machines are a relatively complex system that requires the coordination and cooperation of multiple components. At the same time, attention should be paid to safe operation and maintenance to ensure its normal operation and long-term stable production.
