ABSTRACT:
A clamping assembly for an injection molding apparatus features a double-framed platen unit including a fixed platen, a positioning frame and a clamping frame. Both the positioning and clamping frames are rigidly attached to, or integrally formed with, the fixed platen, but they are otherwise generally mechanically independent of each other. A sliding platen is associated with a linear bearing mounted on the positioning frame so as to be slidable relative to the fixed platen. The clamping frame is configured to receive a drive mechanism for exerting force on the sliding platen towards the fixed platen.
