ある。Actions and Effects of the Invention Namely, first, a soft sheet serving as a skin is attached to one mold having a molding surface corresponding to the surface shape of the part to be manufactured, covering the molding surface, and the soft sheet and molding surface are bonded together. The soft sheet is brought into close contact with the molding surface by creating a negative pressure in the space formed between the parts, and then the other mold, which has a molding surface corresponding to the shape of the back surface of the part, is placed on top of the one mold. By molding and hardening a material made of the same type of material as the skin that is to constitute the base material, it is sandwiched between the soft sheet that is brought into close contact with one molding surface and the other molding surface. The company manufactures parts for the following purposes.

In addition, the materials constituting the base material include hard vinyl chloride, polypropylene, nylon, polyethylene, which is the same material as the skin and has relatively high rigidity.
Alternatively, composite reinforcing materials thereof may be used. In addition,
Such materials may be pre-heated to a plasticized or molten state, or may be in a solid state such as a single powder, and an appropriate form will be adopted depending on the material. .

An adhesive can be applied in advance to the side on which the base materials are bonded together, or the material can be impregnated with an adhesive in advance. Furthermore, it is also possible to further increase the bonding force by biting into each other by lining the back surface of the soft sheets with woven fabric, non-woven fabric, or the like, or by applying uneven processing.

A resin material 42 in a molten or fluid state such as polypropylene or a composite reinforcing material thereof is filled, and the upper mold 16 fixed to the press ram 20 is lowered and overlapped with the lower mold 18. As shown in FIG. 5, the base material 12 is press-molded by pressing the resin material 42 between the soft sheet 36 and the molding surface 22 of the upper mold 16. At this time, the soft sheet 36 and the resin material 42
Since the resin material 42 is made of the same type of material as that of the flexible sheet 36, the resin material 42 is firmly bonded and attached to the back surface of the soft sheet 36 as it hardens. Although the resin material 42 differs depending on its degree of viscosity, it is desirable to place the resin material 42 as uniformly over the entire soft sheet 36 as possible so that no air pockets are formed.

Compared to the case where the skin 14 and the base material 12 are molded using separate molds, the manufacturing equipment can be reduced by approximately half. Further, the base material 12 is press-molded by compressing the resin material 42 on the soft sheet 36 without taking out the molded soft sheet 36 from the lower mold 18, and as the resin material 42 hardens. Since the resin material 42 and the soft sheet 36 made of the same type of material are bonded together, the number of manufacturing steps is reduced and production efficiency is greatly improved. Moreover, a greater bonding force can be obtained than when bonding resins of different materials together, making it easier to apply adhesive to the back surface of the soft sheet 36 or remove the backing such as woven fabric. Interior parts can be manufactured more cheaply.

(C) In close contact with the molding surface" should be corrected to "(C) One of the molds was overlapped with the other, and the mold was attached to one of the molds." (3) On page 4, lines 12 to 17, “the soft sheet was brought into close contact” with “Then, the other mold with a molding surface corresponding to the shape of the back side of the part was The above is corrected to ``overlaid on one of the molds and stretched on one of the molds''. (4) "May be injected" on page 13, line 3.
After , insert a new line and insert the following text. In addition, in the above-described embodiment, the soft sheet 36 is not necessarily made of resin material 4 by creating a negative pressure inside the lower mold 18.
There is no need for the molds 16 and 18 to be brought into close contact with the molding surface 26 in advance prior to the molding and curing of the molds 2 (if both molds 16 and 18 are formed into the shape of the skin 14 when they are overlapped with each other with the resin material 42 in between). The above appended claims provide a method for manufacturing a component in which a relatively soft skin is adhered to the surface of a relatively rigid base material, the method comprising: forming a molding surface for molding the component; a step of preparing a pair of molds, each having one mold; a step of placing a soft sheet made of a material of the same type as the base material on one of the molds so as to cover the molding surface thereof; and one of the molds.
