Plastic injection molding machine It is an important equipment widely used in modern industrial production. Its working principle is to use high pressure to inject molten plastic into the mold, and form the required products after cooling and solidification. Plastic injection molding machine can produce plastic products of various sizes, shapes and complexities, and has the characteristics of high efficiency, high precision, high automation, etc.
The plastic injection molding machine is mainly composed of the following parts:
1. Injection system: including feeding, screw, heating cylinder, storage hopper, injection cylinder and other components. The plastic particles are fed into the screw through the feeding mechanism, and the screw melts the plastic, pushes the molten plastic into the injection cylinder, and finally injects the molten plastic into the mold through high pressure.
2. Mold locking system: mainly composed of template, mold, mold closing mechanism, mold opening mechanism, etc. The mold is pressed by the mold locking 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 high pressure and flow required to drive the opening, closing, lifting, locking and other actions of the injection cylinder and mold.
4. Control system: mainly composed of electrical controller, program controller, operation panel, sensor, etc. The operation of the whole injection molding machine is controlled by the electrical controller and the program controller, such as adjusting the injection speed, pressure, temperature and other parameters to ensure product quality and production efficiency.
injection molding machine The manufacturer's content on "operating principle and components of plastic injection molding machine" is shared here. The operating principle and components of plastic injection molding machine are a relatively complex system, which requires 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.
