Abstract

PURPOSE:To fix an end part of the skin piled upon a base material of an end part of the skin material to the back of the base material easily, by a method wherein a fitting device fixing a bending allowance of the skin is formed by a process of superposition molding is fixed to the base material through the fitting device, which has formed the bending allowance of the skin bent after the superposition molding. CONSTITUTION:The skin 11 covers one side of a base material 14, which is made into a core material, and prossesses a bending allowance 12, which is bent toward a base material 14 side for fixing, on the external circumference of the skin 11. A large number of through- holes 12A is provided on the bending allowance 12 of the skin. A molding recessed part for forming fitting-over parts 13-13 in the through-holes 12A-12A of the bending allowance 12 of the skin 11 and a molding recessed part for forming fitting-in parts 15-15 on the external circumferential part of the back of the base material 14 are formed on a molding part of a molding die. As for the molding part of the molding die, after the skin 11 has been arranged to the same, the other molding die is made to coincide with the same and resin is injected to the molding part. Mold clamping is released and a molded article 16A molded by adhering the skin 11 to the base material 14 is obtained. The bending allowance 12 is fixed by a method wherein the bending allowance 12 of the skin 11 is bent to the back side of the base material and the fitting-over parts 13-13 of the skin 11 is made to press over the fitting-in parts 15-15 of the base material 14.

て外観を悪くする問題があった。(Prior Art) For example, a door trim that is attached to the passenger compartment side of a private car door is made by covering a resin-molded base material with a skin material to improve decorative properties. The edges of the outer skin covering the base material are bent toward the back surface of the base material, and the edges are treated by gluing, welding, or stapling. However, bonding requires time for the adhesive to dry, and there is a problem that the adhesive may seep outside, and welding means requires a special jig for edges with complex shapes, making it difficult to perform. This method has problems such as cracking of the base material and, in the case of thin base materials, staples appearing on the surface, which deteriorates the appearance.

25, the bending allowance 22 is fixed (see FIG. 13). In addition, in this third embodiment, the epidermis 21
The engaging portion 23 formed on the side engages the epidermis 2 through the attached portion 24A.
1, the adhesion is good, and the bracket attached part 24
Since A is bent through the hinge part 24B, the bending allowance is 2.

単に済み都合がよい。(Effects of the Invention) Since the present invention is a means for solving the above-mentioned problems, the expected problems can be solved. In other words, according to the present invention, when the skin and the base material are polymerized and molded using a mold, it is easy to form the engagement means to form the engagement means at the end of the skin. The first part of the skin after polymerization can be fixed by bending and engaging with the back side of the base material, which is convenient because the process can be done easily and in a short time.
