できる。Further, according to the in-mold molding method for interior parts according to the present invention, a resin foam sheet placed above a skin sheet in a mold is foamed toward a hollow body to form a resin foam. Since the skin sheet and the hollow body are integrally molded via the resin foam with a part of the body buried in the resin foam, there is a step of injecting the foam material between the skin sheet and the hollow body. It is also possible to omit the process of bonding the skin sheet and the resin foam layer, thereby reducing production costs, and because the resin foam sheet is foamed to form a resin foam, the foam has a uniform density. layer is formed, which makes it possible to obtain interior parts of good quality.In addition, since a part of the hollow body is buried in the resin foam, deformation of the hollow body due to foaming pressure can be prevented, and the use of one foam material is possible. Only a small amount is required, and the yield can be improved.
