  • Patent number: 6174488
    Abstract: In a method and device for molding a laminated molded assembly by simultaneously forming a resin core member and integrally joining a surface skin member in a die assembly for mold press forming comprising an upper die and a lower die, the moldability of the surface skin member is improved by softening the surface skin member by blowing hot air against the surface skin member from air holes provided in the upper die which is associated with the surface skin member. As a result, the surface skin member can favorably conform to the surface contour of the die surface and the resin core member. Optionally, vacuum suction may be applied to the surface skin member to draw it against the corresponding die surface so as to eliminate the possibility of creating localized gaps between the surface skin member and the corresponding die surface.
