Injection mold processing driving several ways
The driving and driving forces (punching pressure, mould clamping force, falling weight of material, extrusion pressure, etc.) of injection mold processing are provided by the power transmission mechanism of forming machine tools and equipment.
Mechanical and electrical drive, such as punching machine, friction press, forging machinery, etc., are powered by electric motors and rotary motion to drive the drive mechanism, and through the slide block and mould moving parts such as connection movement, to drive the mold directional movement, and the driving force for the mould, make the mould for forming materials.
Electro-hydraulic driven: by injection molding motor driven hydraulic pump or pump hydraulic and water pressure, and through the liquid of hydraulic transmission and control system, produce certain pressure rated to drive the movement part of the mold (such as dynamic model) connected to the hydraulic cylinder or the pistons, driven to move relatively fixed mode for directional translational motion, and to further compression of material, make materials in after forming parts
Pressure forming;Is mainly used for blister and blow molding processing, that is, when the mould is in a state of fixed, the pump will make its produce certain negative pressure type plastic suction stick directly on the mould surface, forming parts, blow molding by pump produce a certain pressure of gas, blow people melt state plastics or hot melt state on the blank cavity glass product, make its expansion and deformation, and post attached to the mold cavity surface, forming parts.
In addition, injection mold processing drives, for example, aluminum profile, plastic profile, sheet, or film, which are generally extruded.The die is fixed on the machine head, the material is extruded through the die, the die for the relative movement of various parts.For example, the plastic profile depends on the spiral movement of the screw rod of the continuous extrusion machine, which pushes the plastic into the mold and passes the mold's profile, and then is cooled and shaped into the profile.Extruded profiles are pulled forward by a traction mechanism for continuous shaping.
