Principle And Structure Of Forming Machine
Dec 08, 2022| Principle
The working principle of the molding machine is similar to that of the syringe for injection. It is a technological process that uses the thrust of the screw (or plunger) to inject the plasticized plastic in the molten state (i.e. viscous flow state) into the closed mold cavity, and then obtain the products after curing and shaping.
Injection molding is a cyclic process, and each cycle mainly includes: quantitative feeding - melt plasticization - pressure injection - mold filling and cooling - mold opening and part taking. Take out the plastic parts and then close the mold for the next cycle.
Structure
⑴ The computer of the molding machine adopts the computer host chip of the imported PLC, which is matched with the LCD screen, the software backup fault self diagnosis system and the error correction function, so that the operation is more convenient. Its control program is designed as a fool, and it can be operated without professional training.
⑵ The molding machine is fully hydraulically driven, with the first stepless hydraulic frequency modulation technology in China, which solves the adaptability of the molding machine to various materials and block types, improves the compactness of materials, and shortens the molding cycle.
