Injection system of the injection molding machine
Function of injection system: injection system is one of the most important components of injection molding machine. Generally, there are three main forms: plunger type, screw type and screw pre plastic plunger injection type. The most widely used is screw type. Its function is that in a cycle of the injection molding machine, a certain amount of plastic can be heated and plasticized within a specified time, and the molten plastic can be injected into the mold cavity through the screw under a certain pressure and speed. After the injection, the molten material injected into the mold cavity is kept in shape.
Composition of injection system: the injection system is composed of plasticizing device and power transmission device.
The plasticizing device of screw injection molding machine is mainly composed of feeding device, barrel, screw, glue passing component and nozzle. The power transmission device includes an injection cylinder, an injection seat moving cylinder and a screw driving device (glue melting motor).
Clamping system of the injection molding machine
Function of clamping system: the function of clamping system is to ensure that the mold is closed, opened and ejected. At the same time, after the mold is closed, sufficient mold locking force is supplied to the mold to resist the mold cavity pressure generated by the molten plastic entering the mold cavity and prevent the mold from slotting, resulting in the poor status of the product.
composition of mold clamping system: the mold clamping system is mainly composed of mold clamping device, machine winch, mold adjusting mechanism, ejection mechanism, front and rear fixed formwork, mobile formwork, mold clamping oil cylinder and safety protection mechanism.

Hydraulic system of the injection molding machine
The function of hydraulic transmission system is to provide power for the injection molding machine according to various actions required by the process, and meet the requirements of pressure, speed and temperature required by each part of the injection molding machine. It is mainly composed of various hydraulic components and hydraulic auxiliary components, in which the oil pump and motor are the power source of the injection molding machine. Various valves control the oil pressure and flow, so as to meet the requirements of injection molding process
