A cylindrical retainer assembly for an injection molding machine includes a cylindrical body having a diametral through channel with a curved wall for receiving a complementarily configured end of an actuator. A spacer disc having a diameter substantially equal to the diameter of the cylindrical retainer body defines an aperture which receives and centers the actuator. The retainer assembly is received within a stepped cylindrical opening in the pin plate of the injection molding machine. An alternate embodiment retainer assembly includes a peripheral flange disposed adjacent the bottom of the retainer which may be received and retained within a cylindrical opening in the pin plate having straight walls and an adjacent recessed region. Pairs of resilient biasing members may be utilized to center the actuator in the cylindrical retainer.
