A device for clamping electromagnetically molds of the injection molding machine comprises a stand on which a fixed board and a guiding mechanism are mounted. A movable board is slidably mounted on the guiding mechanism to slide back and forth in relation to the fixed board. The fixed board is provided with a male mold mounted thereon. The movable board is provided with a female mold mounted thereon. The sliding motion of the movable board toward the fixed board brings about the mold opening action, the mold closing action, and the mold locking action. The movable board and the fixed board are provided with a magnetic force generating mechanism for effecting attraction or repulsion between the movable board and the fixed board. The attraction serves to effect the mold closing action and the mold locking action. The repulsion serves to effect the mold opening action.

Method and device for clamping electromagnetically molds of injection molding machine

An electromagnetic driving device for a mold clamping system is disclosed, which has a stationary plate fixedly mounted on a lathe bed; a mold guiding mechanism mounted parallel on the lathe bed; a movable plate slidably arranged on the mold guiding mechanism, facing the stationary plate, for generating a relative slide to the stationary plate; and a movable plate driving mechanism for driving the movable plate on the mold guiding mechanism. The electromagnetic driving device utilizes magnetic force to drive the linkage, movable plate etc. to perform open-mold movement, close-mold movement, and mold-locking movement.

Linkage type mold clamping device driven by electromagnetic force

An injection molding apparatus has a barrel for conveying a molten substance, a screw, a first base for supporting the barrel, a power unit, a second base for supporting the power unit, links, a motor, a screw driver, a plurality of injection guide links, and an injection connecting plate. The first base is threadedly secured to the bed. The barrel has one end secured to the first base. The power unit is fixed on the second base. The links each have one end connected to the first base and the other end connected to the second base. The screw driver between the bases is moved under the guidance of the injection guide links. The injection guide links penetrate through the second base, having one end secured to the screw driver with the injection connecting plate provided in the second base. The injection connecting plate is pivotably secured to the power unit. These features are adopted to the deformation caused by heat, and provide a closed loop of force, isolation of deformation, and a modular design that is particularly suitable to high speed injection molding.
