  • Patent number: 4790510
    Abstract: A slush mold for molding film moldings such as surface coverings of interior finishing parts of automotive vehicles. The slush mold comprises a mold body having a molding surface of a predetermined shape formed in the inner surface thereof, a skirt capable of being detachably joined to the mold body so as to cover the marginal portion of the inner surface of the mold body other than the molding surface so that a resin film molding is formed only over the molding surface, and guide members for guiding the skirt so that the skirt is joined correctly to the mold body. Thus, the molding material is distributed only over the molding surface, and thereby the yield rate of film moldings is improved and the work in the subsequent process is facilitated.
