ALIGNING DEVICE FOR VERTICAL INJECTION MOLDING MACHINE

摘要

An injection molding machine (10) with a vertically oriented clamp (14) is equipped with a rotatable table (20) for sequentially processing a plurality of bottom mold halves mounted thereon. An aligning device (50) insures accurate positioning of a bottom mold half in molding relation to a top mold half in the clamp by insuring seating of a locating pin (52) in a locating hole (51) in the table after the table has been rotatably indexed to bring a bottom mold half into alignment with a movable top half. The locating pin is secured to an actuator mounted by a guide rail (64) and runner block (65) to the machine's stationary platen. As the pin is pushed into the locating hole by the actuator, the aligning device linearly moves along the guide rail and the table slightly rotates to allow seating of the locating pin into the locating hole.
