发明名称 Method of molding elastic doll heads and mold therefor
摘要 A molding method and a mold therefor capable of forming a doll head of a shape exactly conforming to a mold by blow molding using a safe molding material. A split mold (2, 3) which has an inner surface formed to have a configuration conforming to a shape of a doll head (17) is so arranged that a parting line (18) formed by mold members (2, 3) of the split mold may be formed on a hairline of the hair of the doll head (17) or in proximity thereto. A molding material is constituted by a thermoplastic synthetic resin elastomer as a main ingredient thereof and has a plasticizer and a coloring agent added thereto. The molding material is heated and then dropped in as a parison (15) between the mold members (2, 3) of the split mold spaced from each other. Then, the mold members (2, 3) of the split mold are joined together and air is blown into the split mold. Air is removed through at least one projection such as a nose (5) or the like from a cavity during blowing of air into the split mold (2, 3).
