The driving force (punch force, mold clamping force, material drop weight, extrusion force, etc.) of the injection mold processing movement is provided by the power of the forming machine and equipment through the transmission mechanism.
Electromechanical drive: such as stamping presses, friction presses, roll forging machines, etc., are powered and rotated by motors to drive the transmission mechanism, and connected to the moving part of the mold through sliders, etc., to drive the directional movement of the mold. And the transmitted driving force is applied to the mold to make the mold process the material.
Air pressure forming:mainly used for suction and blow molding processing, that is, when the mold is in a fixed state, a certain negative pressure is generated by an air pump to directly suck and stick the plastic sheet on the mold surface to form a part, blow molding A gas with a certain pressure is generated by an air pump to blow into the cavity of a hot-melt plastic part or a hot-melt glass part to expand and deform, and attach it to the surface of the mold cavity to form a part.

Electro-hydraulic drive: the hydraulic pump or water pump is driven by the injection molding motor to generate hydraulic pressure and water pressure, and through the hydraulic delivery and control system of the liquid, a certain rated pressure is generated to drive the hydraulic pressure connected to the moving part of the mold (such as the movable mold) Cylinders or pistons drive the movable mold relative to the fixed mold to perform a directional and translational movement, and then further compress the material, so that the material becomes a part after the forming process
In addition, injection mold processing drives, such as aluminum alloy profiles, plastic profiles, sheets or films, generally use the extrusion process. The mold is fixed on the machine head, and the material is passed through the mold in the form of extrusion, and the mold is moved relative to various parts. For example, the plastic profile relies on the screw movement of the screw of the continuous extruding machine to squeeze the plastic into the mold and pass through the mold surface, and then cool and shape the molded product. The extruded profile is drawn forward by the traction mechanism to make continuous forming processing.
