ABSTRACT OF THE DISCLOSURE A latch for a mold having an inner mold part sandwiched between fixed and movable outer mold parts comprises a pair of bars each mounted on a respective one of outer mold parts and a locking pin mounted on the inner mold part but displaceable thereon in a direction perpendicular to the direction of motion of the mold parts during opening and closing. One of the bars is formed with a seat in which the pin is snugly engageable when the respective outer mold part is snugly engaged with the inner mold part, and the other outer mold part can only move against the inner mold part when this pin is seated in the recess as otherwise it blocks a control surface of the bar of the outer mold part. A bolt provided in the inner part is also slidable to block displacement of the other outer mold part toward the inner mold part until the one outer mold part is relatively closely juxtaposed with the inner mold part and a control surface of the respective bar cams the bolt out of the way of the other outer part.
