In a method and molding apparatus for laminated molded bodies, a thermal-molding felt and a thermoplastic resin sheet, respectively in hot and soft condition, are set or placed on a mold face of cold-pressing-molding lower mold. A cold-pressing-molding upper mold lowers onto the lower mold to press the the thermal-molding felt and thermoplastic resin sheet. Simultaneously, cooling air is supplied to center portion of the thermal-molding felt through a blowing pipe protruding from mold face of the thermal-molding felt side and intruding into the felt accelerating circulation of cooling air and cooling of the thermoplastic resin sheet.

[ What is claimed is:] [1.] A molding apparatus for a laminated molded body that includes a thermal-molding felt and a thermoplastic resin sheet, comprising:a cold-pressing-molding lower mold provided with a predetermined mold face; anda cold-pressing-molding upper mold placed above said lower mold

[ What is claimed is:] [1.] A molding apparatus for a laminated molded body that includes a thermal-molding felt and a thermoplastic resin sheet, comprising:a cold-pressing-molding lower mold provided with a predetermined mold face; anda cold-pressing-molding upper mold placed above said lower mold in order to press and mold the thermal-molding felt in a predetermined shape, while providing a predetermined clearance between the upper and lower molds,wherein the upper mold carries a movable sealing member for sealing the thermal-molding felt and the thermoplastic sheet at about the outer periphery of the lower mold, the movable sealing member being movable relative to the upper mold while maintaining the same predetermined clearance between the upper and lower molds to break the seal and permit air to escape through a portion of the thermal-molding felt extending to about or beyond the outer periphery of the lower mold to exhaust heat, andwherein one of the lower and upper molds has pressure air holes for delivering cooling and accelerating cooling of the thermal-molding felt, the one of the lower and upper molds having the pressure air holes is adapted to contact the thermal-molding felt so that the cooling air introduced through the pressure air holes penetrates into and through the thermal-molding felt to the thermoplastic resin sheet to force the thermoplastic resin sheet against the other of the lower and upper molds to more precisely mold the thermoplastic resin sheet against the other of the lower and upper molds.
