发明名称 METHOD FOR MOLDING LAMINATED MOLDING
摘要 PROBLEM TO BE SOLVED: To eliminate a difficulty in recycling a residual material of a skin sheet needing a large skin sheet stock space in conventional laminating molding using the sheet with a foaming layer and having a high frequency in replacing rolls for supplying the sheet. SOLUTION: The method for molding a laminated molding comprises the steps of arranging a skin sheet between opened movable mold and fixed mold, closing the molds, injection filling a molten resin filled with a first layer foaming agent in a state in which both the molds are held at a preset first molds opening amount, then relatively spacing apart both the molds, holding both the molds at a preset second molds opening amount while foaming and expanding by the agent, and forming a first layer filer. The method further comprises the steps of relatively spacing apart both the molds, injection filling a second layer core material molten resin in a space formed of the fixed mold and the first filler to form a second filler at a preset third molds opening amount, and sequentially laminating, melting and integrating the sheet, the first filler and the second filler.
