PROBLEM TO BE SOLVED: To ensure a good product appearance on a vertical wall surface, and at the same time, to suppress the decrease of the cushioning performance in a molding method for a laminated molded article for which a resin core material and a skin are integrally molded in molding dies. SOLUTION: A molding die 40 is constituted of a movable side die 50 and a fixed side die 60. After setting the skin 30 in the dies at the time of die opening, the movable side die 50 is clamped, and a molten resin M is fed into the cavity. Thus, the resin core material 20 is molded into a curved surface shape, and the skin 30 is integrated on the surface side. In this case, in the surface shape of the cavity section, the die clearance B1 of the vertical wall surface B is set to be in a range of A1×(1.05 to 1.2) to the die clearance A1 of a general surface A. Thus, the crushing of the skin 30 at the time of molding is eliminated, and the good surface appearance, and the good cushioning performance are ensured. COPYRIGHT: (C)2007,JPO&INPIT |
