PROBLEM TO BE SOLVED: To provide a stamping molding method which prevents occurrence of burrs in a stamping molded article, and does not adopt a conventional share edge part. SOLUTION: When clamping molds by making an upper mold 2 approach a lower mold 1 from a mold opening state P in which the upper mold 2 provided with a pressing mold 3 and a support mold 4 and the lower mold 1 having a workpiece 9 made of fiber reinforced resin or else softened by heating so as to have fluidity, being mounted thereon are opened, at first the support mold 4 is directly brought into close contact with the lower mold 1 by closing surfaces 10, 11 between the upper mold and lower mold on the outer periphery of the article 9 on the lower mold 1, a working mold 3 is caused to slide along guide surfaces 7, 8 for the support mold 4 toward the lower mold 1, the workpiece 9 in a molding chamber 12 formed to be closed between the upper mold 2 and the lower mold 1 is pressed by the pressing mold 3 and, thereby, the workpiece 9 is charged to a fluid chamber 13 remaining between the workpiece 9 and the closing surfaces 10, 11 to manufacture the molded article 20 of stamping molding in the molding chamber 12, wherein an edge 14 exposed to the fluid chamber 13 on the closing surface 11 of the support mold 4 and an edge 17 exposed to the fluid chamber 13 on the closing surface 10 of the lower mold 1 are directly brought into close contact with a form surface of the molded article 20 itself of stamping molding. As the result, the stamping molding mold preventing a molded article of stamping molding from being burred is provided. COPYRIGHT: (C)2010,JPO&INPIT
