发明名称 Method of manufacturing skin-carrying internal-mold expansion molded body of synthetic resin and metal mold used for the same method
摘要 This invention relates to a method for producing cellular molded article in mold pattern of synthetic resin having surface skin which is used, for example, as an automobile interior trim material or the like and a mold pattern for producing thereof. This invention aims to provide a method for producing cellular molded article of synthetic resin having surface skin which has good production efficiency and which comprises that cellular molded article of synthetic resin obtained by cellular molding of expanded beads in which poor melt bonding does not occur and thermoplastic resin skin material united with this cellular molded article of synthetic resin which has excellent appearance without residing beads pattern on its surface, and a mold used for producing thereof. In so-called simultaneous united molding, at least the part of one mold part (5) on which thermoplastic resin skin material (3) is set is made of gas permeable metal mold, gas permeable ceramic mold or gas permeable electron casted mold (5d) having fine gas permeable holes of not more than 100 mum of diameter on the whole surface (5a) and at least during steam heating and before expanding expanded beads (8), one mold part (5) on which thermoplastic resin skin material (3) is set is made to be the upper part, and the other mold part (6) is made to be the lower part.
