The above is an embodiment of the method for molding an interior base material according to the present invention. According to this method, a resin felt formed larger than the lower molding surface of the lower mold is placed on the lower molding surface. Then, the outer periphery of the large resin felt is pressed against the outer periphery of the lower molding surface of the lower mold by the end surfaces of a plurality of cam plates that are slidably arranged on the outer periphery of the lower molding surface of the lower mold, and the resin felt is pressed along the outer periphery of the lower molding surface of the lower mold. It can be heated and press-molded by moving it to the desired position.
There is no need to perform end treatment on the interior base material after molding.
Because no scraps are generated, the density of the ends of the interior base material is high, and the strength of the ends is increased, there is no risk of the ends of the base material being damaged during handling, making it extremely easy to handle. It is possible to obtain a method for molding an interior base material that is extremely economical.
