Abstract
A rotatable platen assembly is adapted to support a mold used in multi-shot plastic injection molding. The platen assembly includes a non-rotatable machine platen having a central bore formed therethrough. A non-rotatable base plate is connected to the machine platen, the base plate having a central opening aligned with the central bore of the machine platen. A rotating plate is adapted to retain a mold thereon. The rotating plate is provided with a rotatable center axle passing through the central opening in the central bore, and a gear mounted for rotation on the axle. A rack system is engageable with the gear for moving the mold rotating plate between a starting position and a finishing position. A shock absorber arrangement is mounted externally of the base plate for dampening the momentum of the rotating plate between the starting position and the finishing position.
