ABSTRACT:
In a system for the production of molds for casting, a pair of pattern plates are disposed in an opposed facing relationship with a frame located therebetween in a manner whereby the opposing pattern surfaces of the plates, together with the frame, define an enclosed cavity within which a casting mold section may be formed. The frame is preferably provided with an opening through which the cavity may be filled with molding material which, after hardening, forms a mold section. After separation of the pattern plates and frame, the mold section is conveyed into assembled relationship with one or more other mold sections in order to form a mold for casting. Pattern plates and frames may be arranged in a mass production facility to continuously form mold sections which, when assembled, will provide a mold stack for producing multiple castings.
