PROBLEM TO BE SOLVED: To easily and efficiently manufacture a soft resin molded body by laminating a skin layer and a resin foamed body. SOLUTION: A cavity 20 is formed by a lower mold 12, a first horizontal mold 14, a second horizontal mold 16 and an upper mold 18 which constitute a molding device 10. An injection machine 22 is installed to the first horizontal mold 14 so that a raw material 28 flows along the extending direction of the cavity 20, and an air blow pipe 30 is provided in the second horizontal mold 16. When the raw material 28 is injected from the injection machine 22, a gas such as a compressed air is supplied to the cavity 20 via the air blow pipe 30, and the material 28 is pressed to the side of the injection machine 22 by such a gas. During the closed cells 40 are formed in the material 28 in such a state, the pressure of the above gas is reduced. Thereby, the closed cells 40 disperse crack to communicate with each other to form the open cells. COPYRIGHT: (C)2011,JPO&INPIT |
