Patent ID: 7235206

Claim:
A method for producing a multilayer molded article, comprising the steps of: placing a first skin material and a second skin material adjacent to each other on the same plane between a pair of male and female mold parts, supplying a molten thermoplastic resin to the rear surface of the first skin material from a first gate formed in a molding surface of the mold part located at the rear sides of the skin materials and supplying a molten thermoplastic resin to the rear surface of the second skin material from a second gate formed in the molding surface, and adhering the skin materials and the molten thermoplastic resins to each other to produce a multilayer molded article, wherein, when the thermoplastic resins are supplied, a resin blocking member is projected from the molding surface towards the rear sides of the skin materials, the resin blocking member being embedded in the molding surface so as to extend substantially along a boundary portion the first skin and said second skin material, and arrival timings of the resins at the boundary portion are controlled by blocking a flow of the resin toward the boundary portion with the resin blocking member and withdrawing the resin blocking member into the mold part before filling of the resin from the first gate into a mold cavity is completed and before filling of the resin from the second gate into a mold cavity is completed.
