AbstractA mold weight for use with foundry sand molds comprises a frame assemblage including a pair of spaced frame members connected by rods. A plurality of segmental weight elements are disposed between the frame members and carried by the rods. The weight elements are further disposed to avoid the area of the mold surface that contains the down sprues. The frame members and weight elements are movable, within limits relative to the connecting rods and to each other. Weight elements are made available in a plurality of lengths so that the mold weight configuration can be varied in contemplation of sand molds requiring different down sprue locations.
