Abstract
A rotatable platen for supporting a plastic molding device includes a bottom clamp plate enclosing a central pillar supporting an axially rotating gear. The rotating gear turns a vertical shaft attached to a top of the gear. A longitudinal slot in the clamp plate receives a rack assembly that engages the rotating gear and is driven by a hydraulic piston. The vertical shaft passes through a wear plate, a lower rotating plate, a thrust bearing, an intermediate housing enclosing a portion of the thrust bearing and the top of the shaft turns an upper rotating plate that engages the molding device.
