  • Process for electrically clamping molds to platens
    Patent number: 5785908
    Abstract: An electric mold clamping mechanism containing a pair of clamping members is activated by an electric motor. The electric motor operates a threaded piston with acme threads which in turn operate a drive plate to extend and retract the clamping members. The clamping members are used to hold a mold plate in an injection molding machine. The clamping members are pivotally attached to a drive plate mechanism and have a surface which mates with a wedge cam to force the clamping member against the mold plate. The stroke of the clamping mechanism is regulated by an amperage draw on the electric motor. A limit switch is used to terminate the end of the retracting stroke. An indicator light is used to indicate the clamping position of the device.
