ABSTRACT:
A mold which comprises a pair of mating, openable and closeable mold halves and a lock to hold the mold halves together. The lock is defined by a recess in the outer surface of one of the mold halves. A lifting bridge crosses the recess, being proportioned to permit a lifting hook in the recess to pass underneath to engage the bridge. An elongated member is secured to the other of the mold halves, being slidably extendable into the recess when the mold halves are substantially closed. The elongated member defines a longitudinal slot facing outwardly of the recess in closed position to receive at least a portion of the lifting hook as the hook engages the bridge. The slot defines an end opposed to the other mold half which is closed, to prevent a hook portion in the slot from sliding past the opposed end. Thus, the mold in closed position cannot be opened while the lifting hook is present in the slot.
