Abstract

PURPOSE:To simultaneously carry-out the fixation and shaping of each member by successively arranging and closely attaching a member which covers a finisher body, etc. as core member and a decoration member onto a molding lower mold and superposing the core member onto the above-described members and applying a molding upper mold. CONSTITUTION:Onto a molding lower mold 1, a deep drawn part 3 projecting for a common flat surface part 2 is formed, and a loop-shaped thin wall 4 is installed in projection onto the flat surface part 2 at the separated position on the periphery of the deep drawn part 3. Onto the flat surface part 2, the first member 5 in flat-plate form which is made of, for example, polyvinylchloride is arranged, and the terminal part 7 of an opened port 6 is loaded onto the upper edge 4a of the thin wall 4. Further, onto the deep drawn part 3, the second member 8 consisting of the cloth member packing-applied with a thermoplastic-resin member is arranged, and after a terminal 9 is loaded onto the terminal 7, the both members 5 and 8 are attached closely by absorbing air from an air drawing-out hole 10. Then, a core member 11 consisting of the thermoplastic-resin member in softened state is superposed onto the both members 5 and 8, and molded by using the molding upper mold 12.

である。B. Means for Solving the Problems In order to achieve the above object, the present invention has a deep drawing part that protrudes from the plane part, and a loop-shaped protrusion is provided on the plane part around the deep drawing part. A flat first member made of, for example, a polyvinyl chloride sheet is placed on the flat surface of the lower molding mold made of the thin wall, and placed on the thin wall at the end of the first member, and the deep drawing is performed. A second member made of, for example, a thermoplastic resin or packed cloth material is arranged in advance in the deep drawing part (together formed into a box shape), and the end of the second member is placed on the end of the first member. The first and second parts are brought into close contact by sucking air through air suction holes previously formed in the mold, and then a core material made of a thermoplastic resin material that has been heated and softened in advance. A method for producing a trim material for an automobile, characterized in that the first and second members are stacked on top of each other and sandwiched by a molding upper mold, and the overlapping portion of the ends of the first and second members is surrounded from the periphery. This is what I did.
