ABSTRACT:
Apertures are formed in the top surface of the platen assembly. A resilient diaphragm extends across each aperture and is extended upwardly through the aperture by a plunger. The extended diaphragm protrudes into sand within the flask and locks the sand mold against movement parallel to the top of the platen assembly.
