Introduction of several ways of injection mold processing drive!

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. 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 design, so that the plastic 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) The 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 workpiece after forming.

Air pressure forming: mainly used for blister and blow molding processing, that is, when the mold is in a fixed state, the air pump will make it generate a certain negative pressure to directly suck the plastic sheet onto the surface of the mold to form a product, blow molding The gas with a certain pressure is generated by the air pump, blowing into the cavity of the hot-melt plastic part or hot-melt glass blank to expand and deform it, and attach it to the surface of the mold cavity to form a part. 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 extrude 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.
