Method of rotationally molding a synthetic resin doll

摘要

A method for rotationally molding synthetic resin dolls using an automatic control mechanism, a mold holding mechanism, a robot mechanism having a mold cover opening and closing means, a mold releasing means for releasing a molded product from the mold, mold release detecting and cleaning means; a raw material charging means, and a heating and cooling means. The method includes detecting the mold release of the molds opened by the mold holding mechanism and cleaning the molds. Quantitatively charging a raw material of thermoplastic synthetic resin into the mold in a solid state and closing the cover. Inserting the mold into a heating furnace of a heating mechanism and rotating the mold to form a synthetic resin molten skin layer on the inner wall of the mold. Once the layer is formed the mold is moved into a cooling chamber of a cooling mechanism and the skin layer is solidified while continuing to rotate the mold. When the layer is solidified the mold is moved to the mold releasing unit. The cover of the mold is opened and the molded product is removed.
