Important Parts Of Vertical Injection Molding Machines

Aug 29, 2025 Leave a message

The key parts of a vertical injection molding machine mainly include the following categories:

 

Mold Clamping System Components

 

• Clamping Cylinder: Provides power for mold closing and opening, ensuring reliable mold closing and opening.

• Platen: Includes the fixed platen and movable platen, used to mount the mold and withstand the pressure during injection.

• Guide Mechanism: Such as guide pins and guide bushings, ensures the smooth and precise movement of the movable platen.

Injection System Components

• Barrel and Screw: These are the core components for plasticizing the raw material. The rotation of the screw heats, melts, and pushes the raw material into the mold.

• Nozzle: Connects the barrel and mold, controlling the injection direction and flow rate of the molten material.

• Heating Coil: Installed on the outside of the barrel, provides heat for plasticizing the raw material.

 

Hydraulic System Components

 

• Hydraulic Pump: Provides power for the entire hydraulic system and outputs pressurized oil.

• Hydraulic Valves: Includes pressure valves, flow valves, directional valves, etc., controlling the pressure, flow rate, and direction of the hydraulic oil.

• Oil tank: Stores hydraulic oil and also dissipates heat and filters impurities.

Electrical control system components

• Controller: Such as a PLC (Programmable Logic Controller), it is the control core of the entire machine, coordinating the operation of various components.

• Sensors: These include temperature sensors and pressure sensors, which monitor the equipment's operating status in real time and provide feedback to the controller.

• Motor: Provides power for screw rotation and mold clamping cylinder operation.

 

Other auxiliary components

 

• Mold mounting device: Used to secure the mold and ensure accurate positioning during the injection molding process.

• Safety devices: Such as safety door switches and overload protection devices, which ensure the safety of operators and equipment.
