Injection molding machine
Injection molding machine is an important equipment widely used in the production of plastic products, its main function is to form plastic products of various shapes by heating and plasticizing thermoplastic or thermosetting plastics, and injecting them into molds. Here is a detailed description of the injection molding machine.
Function and composition of the injection unit Function
The main function of the injection unit is to heat, melt and inject plastics. It conveys the plastic from the barrel into the mold cavity through a screw or plunger, while controlling the injection speed, pressure, and dwell time to ensure molding quality.
Composition
The injection unit usually consists of the following parts: Barrel: used to store and heat plastic pellets so that they melt into a liquid state.
Screw or plunger
Pushes the molten plastic into the mold cavity. More common are screw injection units, which convey the plastic by rotating and moving axially.
Heating device
The heater inside the barrel is used to heat the plastic to a suitable temperature to make it flowable. Nozzle: Molten plastic enters the mold cavity through the nozzle.
Cylinder (hydraulic unit)
Provides the thrust required for injection.
|
Double rod injection structure,injection more stable.
Injection cylinder and drive shaft intergrated to ensure the injection mechanism coaxiality and straightness.
Injection adopts high precision linear guide rail to reduce the load of storage stable back pressure. |
