られる。(Prior Art) This type of interior panel 10 is used as a vehicle door trim, for example, as shown in FIGS. 3 and 4, and includes a substrate 11 made of a wooden hard boat, a pad layer 12 made of polyurethane foam, Consisting of the epidermis 13, the front side includes a concave portion 10a and a convex portion 10b constituting an armrest.
10c is formed. The following method is adopted to manufacture such an interior panel 10. That is, first the substrate 1
1 is molded into a predetermined shape and the skin 13 is molded to have a predetermined pattern on its surface, and then both these 11 are molded.
．． A method has been adopted in which a stock solution of foamed polyurethane is injected between 11 and 13 and foam molded to form the ρ pad layer 12 integrally with both 11 and 13. However, interior panels manufactured by such a manufacturing method have the disadvantage of high cost. For this purpose, the pad layer 12 and the skin 13 are bonded in advance, and this composite material is set and molded in the upper mold 21 of a vacuum molding mold as shown in FIG. A method of integrating these three components 11 to 13 can be considered.

ができる。(Operations and Effects of the Invention) According to this manufacturing method, when the composite material formed by adhering the pad layer to the substrate is suction-adhered to the lower mold, the pad layer sinks to reduce its thickness, and the interior board in the pad layer A considerable gap is created between the bottom and top surfaces of the recess and the skin suctioned to the upper mold. This lick prevents the skin from sliding against the adhesive applied to the area during pressing, and when the suction adhesion to the composite material is released during pressing, the pad layer no longer sinks and its thickness is restored. , the epidermis is firmly adhered to one side of the padding layer. For this reason, even interior panels having extremely small recesses having the above-mentioned angles θ1 and θ2 can be manufactured without any problems.

易に製造することができる。The composite material is made by bonding the material of the substrate 11 and the material of the pad layer 12 with an adhesive, and is formed in advance using vacuum molding molds 21 and 22 shown in FIG. Set. The pad layer 12 made of such a composite material is breathable and has a non-breathable film 12a on its upper surface.
In this embodiment, the film 12a is bonded to
Polypropylene film is used as On the other hand, the skin 13 is set on the upper die 21. The skin is non-air permeable, and in this embodiment, a vinyl chloride sheet is used as the skin 13. In this state, when the upper mold 21 and the lower mold 22 are suctioned, the composite material is removed from the lower mold 22.
The skin 13 is attracted to the upper surface, and the skin 13 is attracted to the lower surface of the upper mold 21, and by processing the upper mold 21, the composite material (11, 12) and the skin 13 are pressed between the molds 21 and 22. Figure 2 shows an enlarged view of the arrow ■ in Figure 1.
When the lower mold 22 is sucked, negative pressure acts on the film 12a of the pad layer 12 through the substrate 11, causing the pad layer 12 to sink from the state shown by the two-dot chain line to the state shown by the solid line in FIG. For this reason, when processing the upper mold 21, the parts corresponding to the bottom and top surfaces of the recess 10a in the door trim 10, that is, the surfaces 12b and 1-2c of the pad layer 12 and the surfaces 13c and 13 of the skin 13, are
Even if the adhesive is applied to the upper surface of the pad layer 12, that is, the film 12a, the surfaces 13c and 13d of the skin 13 do not come into sliding contact with the surfaces 12b and 12c of the pad layer 12 because a gap is created between the surfaces 12b and 12c of the pad layer 12. It can be pressed without any problem. During pressing, when the suction to the lower die 22 is released, the pad layer 12 is released, no longer sinks, and returns to its original thickness. Therefore, the skin 13 is reliably adhered to one side of the pad layer 12. Therefore, the angle θ of the door trim 10
1. Door trim 10 that applies even when θ2 is small
can be manufactured without any problems, and stitches 13a, changing grains 13b, etc. can be easily manufactured on the surface of the skin 13.
