ABSTRACT:
A molding-system clamp assembly of a molding system is disclosed, and includes a clamp piston, and a clamp ram, the clamp ram and the clamp piston each including inter-meshable structures to selectively inter-mesh the clamp piston to the clamp ram, in the unmeshed position the clamp piston and the clamp ram do not inter-mesh relative to each other, and inter-abuttable structures to selectively inter-abut the clamp piston relative to the clams ram, the inter-abuttable structures having an interposing body abuttable against the clamp ram and the clamp piston, the inter-abuttable structures to abut with each other so that the clams piston makes contact with the interposing body, and the inter-abuttable structures to transfer a mold-break force so that the mold-break force is applied from the clamp piston against the interposing body, and in response the mold-break force is transferred from the clamp piston through the interposing body and to the clamp ram, and once mold break has occurred, the clamp piston is deactivated so that the mold may be opened.
