のである。Conventionally, fiber products such as hardboards, semi-hardboards, and insulation boards or their molded products (hereinafter, these fiber products or molded products are abbreviated as base materials) are lightweight, heat resistant, and sound absorbing. It is widely used as interior material for automobiles, such as door trims, package trays, air ducts, and center pillars. Since these base materials cannot be attached to a mating member by themselves, attaching fasteners, brackets, cage retainers, etc. to the base material requires separate pieces.
After assembling in advance using fixing means such as gluing, caulking, or pinning, the assembly is then attached to a predetermined mating member via a piece. However, in order to attach the piece to the base material using a fixing means, parts such as adhesive and caulking pins are required to fix the piece to the base material, and mounting to the base material is not possible. It was difficult to position the pieces on a hill, and the finish did not have good alignment, which was not aesthetically pleasing. Therefore, the present invention (1) is an attempt to solve the conventional drawbacks when attaching a fiber base material. Namely, one aspect of the present invention is to injection mold a piece to attach a fiber base material. The purpose of both molding and attachment is to provide a method for forming a protruding piece on a fibrous base material in which the piece can be fixed to a predetermined portion of the base material, thereby eliminating the need for parts such as caulking pins and making positioning easy. For easy attachment and a beautiful appearance after finishing, it is possible to form a piece on the base material.

The concave mold 8 is held by a holding means (not shown). Next, insert the tip 9A of the resin injection 11!9 into the injection hole 8 of the concave mold 8.
C, and molten synthetic resin such as polypropylene is injected into the molding recesses 8B and 7B of the concave mold 8 and the convex mold 7. In this example, the injection temperature is 220 to 230°C, the injection pressure is 10
Molten polypropylene was injected at 0%. After injection, by cooling and removing the convex mold 7 and concave mold 8, it is possible to obtain a processed product 13 in which the mounting piece 10 is fixedly attached to the base material 1. That is, by injection molding, mounting pieces 10 are molded at the positions of the holes 5 and 5 on the side of the curved part 4 of the base material 1, and
1Ig At the 5°5 position of the through hole on the surface side of the curved portion 4, a stop portion 11 having a shape h'Z larger than the through holes 5, 5 is formed, and the mounting piece 10 and the stop portion 11 are attached to the through holes 5, 5. The base material 1. is joined via a resin connecting part 12 which is inserted into the base material 1. Sea hole 5. Since the diagonal circumferential portion is clamped and molded ζh, the mounting piece 10 has good adhesion properties without any problems.

用土好まし。Since the pieces are fixed to the crosspiece, the pieces are firmly fixed, and the pieces can be formed and fixed at the same time. It is convenient because it is easy to form and fix the pattern onto the base material. In addition, in the conventional installation method, when the pieces were cut into pieces, a caulking pin, a shielding agent, etc. were required, but according to the invention, such items are not necessary, and the assembly is done by reducing the number of parts. Preferably used soil to save money.
