<p>A clamping assembly (10) for an injection molding apparatus features a double-framed platen unit including a fixed platen (12), a positioning frame (14) and a clamping frame (16). Both the positioning and clamping frames (14, 16) are rigidly attached to, or integrally formed with, the fixed platen (12), but they are otherwise generally mechanically independent of each other. A sliding platen (18) is associated with a linear bearing (20) mounted on the positioning frame (14) so as to be slidable relative to the fixed platen (12). The clamping frame (16) is configured to receive a drive mechanism (22) for exerting force on the sliding platen (18) towards the fixed platen (12).</p> |
