ABSTRACT:
A mold comprises a pair of openable and closeable mold halves separable along a parting line. By this invention, each mold half defines a recessed outer surface portion which communicates with the recessed portion of the other mold half in the closed position. Each mold half defines a bridge portion which extends over its recessed portion and is positioned adjacent to the parting line. Thus, a lifting hook may pass into the recess defined by the outer surface portion to engage the bridge portion of a separate mold half, or to engage both bridge portions of both mold halves in the closed position.
