Abstract
The present invention relates to stack mold carriers in an injection molding machine with a rotating turret. Services to the rotating turret are provided by a rotary union attached to the translating mold carrier at the turret's axis of rotation. Hence, services such as oil, water, air and electrical power are provided to the rotating turret thereby allowing the turret to rotate in either direction. The rotating turret is attached to linkages which open and closed the molds through connection to a moving and a stationary platen which interface with the rotating turret to form molded articles therein.
