LAMINATED RESIN MOLDED ARTICLE AND ITS MANUFACTURING METHOD

Japanese Patent JP2009073044

A

To easily and efficiently manufacture a soft laminated resin molded article with a surface layer and a resin foam body layered thereon.

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 configuring a molding device. An injection machine 22 is installed so that a raw material 28 flows along the extending direction of the cavity 20 with respect to the first horizontal mold 14, while an air delivering pipe 30 is provided to the second horizontal mold 16. When injecting the raw material 28 from the injection machine 22, gas such as compressed air is supplied to the cavity 20 via the air supply pipe 30 and the raw material 28 is pressed to the side of the injection machine 22 by the gas. Pressure of the gas is decreased when independent air bubbles 40 are being molded inside the raw material 28 in the above condition. Thereby, cracks are propagated from each independent air bubble 40 and connected with each other to form continuous air bubbles.
