Molded part ejection apparatus

Apparatus for separating molded parts from a mold surface, said apparatus comprising:

• a) a movable platen having a longitudinal axis and movable along the longitudinal axis for carrying and transporting a first mold member into and out of cooperative engagement with a second mold member to selectively close and open a mold cavity defined by the mold members;
• b) first molded part ejector means carried by the movable platen for providing a linear mold part separating force, wherein the first molded part ejector means includes a linear actuator and at least one ejector rod positioned for axial movement within an aperture in the movable platen;
• and
• c) second molded part ejector means carried by the movable platen for providing a rotational mold part separating force, wherein the second molded part ejector means includes a motor carried by the movable platen for providing torque about an axis extending in a longitudinal direction of the injection molding machine.
