  • Linkage type mold clamping device driven by electromagnetic force
    Patent number: 6540494
    Abstract: 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.
