ELECTRIC MOLD CLAMP

摘要

An electric mold clamping apparatus (20) and system are disclosed. A clamping mechanism (80) containing a pair of clamping members (40) is activated by an electric motor (62). The electric motor (62) operates a threaded piston (76) with acme threads which in turn operate a drive plate (110) to extend and retract the clamping members (40). The clamping members (40) are used to hold a mold plate in an injection molding machine (22). The clamping members (40) are pivotally attached to a drive plate mechanism and have a surface which mates with a wedge cam (140) to force the clamping member (40) against the mold plate. The stroke of the clamping mechanism (80) is regulated by an amperage draw on the electric motor (162). A limit switch (162) is used to terminate the end of the retracting stroke. An indicator light (194) is used to indicate the clamping position of the device (20).
