Talking about the driving methods of injection mold processing!

The drive and driving force of the injection mold processing movement (punching force, mold clamping force, material drop weight, extrusion force, etc.) are provided by the power of the forming machine tool and equipment through the transmission mechanism. Follow the injection mold processing manufacturers to understand the driving methods of injection mold processing are as follows! Electromechanical drive: such as stamping machines, friction presses, roll forging machines, etc., are powered and rotated by electric motors to drive the transmission mechanism, and are connected to the moving parts of the mold through sliders, etc. to drive the directional movement of the mold. And the transmitted driving force acts on the mold, so that the mold can shape the material. Electro-hydraulic drive: that is, the hydraulic pump or water pump is driven by an injection molding motor to generate hydraulic pressure and water pressure, and through the hydraulic transmission 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 a moving mold) Cylinder or piston drives the movable mold to perform directional translational movement relative to the fixed mold, and then further compresses the material, so that the material becomes a pneumatic forming after the forming process; it is mainly used for blister and blow molding processing, that is, when When the mold is in a fixed state, the air pump makes it generate a certain negative pressure to directly suck the plastic sheet onto the mold surface to form a part. Blow molding is to generate a certain pressure of gas through the air pump, and blow it into the hot-melt plastic. The cavity of the workpiece or the blank of the hot-melt glass product is expanded, deformed, and attached to the surface of the mold cavity to form a product.

In addition, injection mold processing drives, such as aluminum alloy profiles, plastic profiles, sheets or films, generally adopt the extrusion molding process. The mold is fixed on the machine head, and the material passes through the mold in the form of extrusion, and various parts are formed by relative movement of the mold. For example, the plastic profile relies on the helical movement of the screw of the extrusion machine to squeeze the plastic into the mold and pass through the surface of the mold, and then cools and shapes the profile.

The extruded profile is drawn forward by the traction mechanism, so that it can be continuously formed.
