ABSTRACT:
A core box assembly includes an outer aluminum box containing an inner plastic or wooden mold section having a core depression therein adapted to receive mold sand. A strike-off surface on the box and mold section surrounds an opening providing access to the core depression. A peripheral portion of the strike-off surface is removed so that a step is formed around the periphery of the aluminum box. A portion of flat steel plate is formed with a centrally disposed opening therethrough and is fixed on the assembly with its upper surface in the plane of the strike-off surface, its outer boundary coincident with the outer boundary of the aluminum box, and its inner boundary abutting the step.
