ABSTRACT:
A die locking mechanism for a molding apparatus including stationary and movable die assemblies, has a stop bar movable back and forth with respect to the stationary frame structure in a direction parallel with the direction of movement of the movable die assembly, and a locking member rockable between first and second angular positions about a fixed pivot axis. The locking member has a cam lobe portion generally arcuately curved about the pivot axis and is engageable with the stop bar, the cam lobe portion being disengaged from the stop bar with the locking member in the first angular position and being engageable with the stop bar with the locking member in the second angular position so that the movable die assembly is locked in position with respect to the movable die assembly.
