PROBLEM TO BE SOLVED: To provide a molding manufacturing apparatus capable of dispensing with a finish-machining work which has been inevitable, manufacturing a casting at low cost, and manufacturing even a forged product superior to a casting in the aspects of the material characteristics and strength by constituting a pressing mold of a special structure. SOLUTION: The molding manufacturing apparatus has at least two molds 1 and 2 to form a forming space S to store molten metal for molding, and at least one of the two molds 1 and 2 is constituted to be the pressing die 2. The pressing die 2 is provided with a main pressing die 8 and a sub pressing mold 9 for forming a flow part which are freely movable relative to each other so that they separate from or come closer to the forming space S. The main pressing die 8 and the sub pressing die 9 are pressed by a main pressing means 10 and a sub pressing means 11, respectively. COPYRIGHT: (C)2005,JPO&NCIPI
