ABSTRACT:
The invention relates to an adjustment device for a valve pin on an injection molding machine, and particularly on a multi-cavity machine, having a plurality of valve pins mounted on a common yoke plate which is actuated by a common actuator. The adjustment device includes a pin holder for holding the valve pin, and a locking member. The pin holder has two threaded portions. The first threaded portion is adjustable within a threaded receiving hole in the yoke plate. The second threaded portion is received by the locking member. The locking member has a bottom shoulder which butts against the yoke plate, and retains the pin holder in place.
