Abstract:
PROBLEM TO BE SOLVED: To provide a method and an apparatus for manufacturing a three-dimensional molded product.SOLUTION: A method for manufacturing a three-dimensional molded product which comprises an aluminum resin composite laminated plate, in which a face bar is laminated on both faces of a core material comprising a resin foam, and has a top wall or a bottom wall, a side wall continuous with those walls, and a flange part connected to the side, in which a metal mold device equipped with a die mold comprising a core and a form block and a wrinkle pressing plate is used, a flat plate-like blank comprising the aluminum resin laminated plate is inserted between the die mold and a punch, the punch is pushed in the form block while sandwiching a marginal part of the blank by the die mold and the wrinkle pressing plate, and the blank material is drawn in conformity with the form block while stretching the blank. A long side length of the blank is set to 50 to 600 mm, a thickness of the blank is set to 2 to 10 mm, and a width of the flange part is set to 5 to 20 times of the thickness of the blank, and the blank is molded while gradually weakening a wrinkle pressing force applied during molding.SELECTED DRAWING: Figure 1
