PROBLEM TO BE SOLVED: To shorten a cycle time of a mold making in a simple structure at a low cost by charging molding sand into a conveying frame of a carrier plate at the charging position of the molding sand during squeezing with a squeezing head while shifting the molding sand in a molding flask from the conveying frame of the carrier plate on a squeezing table. SOLUTION: The conveying frame surrounding a pattern base board, is arranged so as to be vertically movable, on the carrier plate. The molding sand necessary for one mold amount, is charged into the conveying frame at the charging position of the molding sand in a state in which the conveying frame is at an ascending position, where the abutting surface of the molding flask is protruded out from the board surface of the base board. The carrier plate charging the molding sand into this conveying frame, is shifted to the squeezing table and the molding flask and an upper auxiliary frame are piled on the conveying frame. The squeezing table and the squeezing head are mutually approached and the conveying frame is retreated, and the molding sand in the conveying frame, is shifted into the molding flask and squeezed to make the mold.
