What are the driving modes of plastic injection mold processing?

Electromechanical drive: such as punching press, friction press, roll forging machinery, etc., are powered and rotated by electric motor to drive the transmission mechanism, and connected with the moving part of the mold through slide block, etc., to drive the directional movement of the mold, and use the transmitted driving force to the mold, so that the plastic injection mold can form and process the material.
Electro-hydraulic drive: that is, the injection molding motor drives the hydraulic pump or water pump to generate hydraulic pressure and water pressure, and through the hydraulic transmission and control system of the liquid, the rated pressure generated drives the hydraulic cylinder or piston connected to the moving part of the mold (such as the moving mold), drives the moving mold to move in the direction of translation relative to the fixed mold, and then further compresses the material to make the material become a part after the forming process.
Air pressure forming: It is mainly used for plastic absorption and blow molding processing, that is, when the mold is in a fixed state, the negative pressure generated by the air pump will directly suck the plastic sheet onto the mold surface to form a part, while blow molding is the gas generated by the air pump to blow into the blank cavity of the hot melt plastic part or the hot melt glass part to expand, deform, and attach to the surface of the mold cavity to form a part.
In addition, plastic injection mold processing drives, for example, aluminum alloy profiles, plastic profiles, sheets or films, generally adopt extrusion forming process. The mold is fixed on the machine head, and the material passes through the mold in the form of extrusion to make relative movement on the plastic injection mold. For example, plastic profiles rely on the continuous spiral movement of the screw of the extrusion machine to squeeze the plastic into the mold and pass through the surface of the plastic injection mold, and then cool and shape the molding material. The extruded profile is pulled forward by the traction mechanism to enable continuous forming processing.
