The driving and driving forces (stamping force, clamping force, drop weight of data, extrusion force, etc.) of the injection mould processing movement are provided by the power transmission mechanism of the forming machine tool and equipment.
Mechanical and electrical drive: such as punch, friction press, roll forging machinery, etc., are powered and rotated by motors to drive the transmission mechanism, and through slider and die movement, local stop convergence movement, in order to drive the directional movement of the die, and the transmission of driving force on the die, so that the die to stop forming processing of data.
Electro-hydraulic drive: that is to say, the injection-moulding motor drives the hydraulic pump or water pump to produce hydraulic pressure and water pressure, and through the hydraulic delivery and control system of the liquid, produces a certain rated pressure to drive the hydraulic cylinder or piston connected by the moving parts of the die (such as the moving die), and the differential die is relative to the fixed model to stop the movement of directional translation, and then the data is stopped to further tighten, so as to make the capital available. Material is pneumatic forming of injection moulds after stopping forming processing; mainly used for suction and blow moulding processing, that is, when the moulds are in a fixed state, the plastic sheets are directly sucked onto the surface of the moulds by the negative pressure generated by the air pump to form parts, while blow moulding is a gas which produces a certain pressure through the air pump to blow hot-melt plastic parts or hot-melt glass parts. The blank cavity is expanded and deformed, and attached to the surface of the die cavity to form a part.
Laminated Injection Mold
In addition, extrusion process is commonly used to drive injection mold processing, such as aluminium alloy profiles, plastic profiles, sheets or films. The die is fixed on the machine head, and the data are extruded through the die, and the relative movement of the die is made into various parts. For example, plastic profiles rely on the spiral movement of the screw of the continuous extrusion machine to extrude the plastic into the mould and pass through the surface of the mould, and then cool the shaped material. The extruded profile is pulled forward by the traction mechanism to stop the continuous forming process.
