ABSTRACT:
A cam slide retainer for injection molds including an elongated rounded latch groove formed in the cam slide and a corresponding lock in the core retaining plate. The slide retainer is simple to install since the body portion of the lock is circular and is installed by press fitting into the core retaining plate from the back. A shoulder on the body portion is received in a counterbore to properly position the elongated rounded lock plunger head to extend above the inside surface of the core retaining plate. A flat key surface on the shoulder properly aligns the plunger head to extend transverse to the direction of the slide movement. The elongated rounded groove in the cam slide is positioned to matingly receive the elongated rounded plunger head when the slide is moved to the position away from the molded part to releasably lock the cam slide in position.
