    • The present invention provides a molding die and a control method thereof aimed at shortening cycle time from heating to cooling of a molding cavity of the die with a simple and inexpensive configuration. In a molding die equipped with a molding cavity to mold a base material, a magnetic die material is used for the molding cavity, cooling means to feed a refrigerant is installed inside the molding cavity along a molding face and heating means by high-frequency induction is installed around the cooling means, and the molding cavity is alternately heated and cooled repeatedly by the heating means and the cooling means when the base material is molded with the molding cavity. Here, the cooling means includes a tubular body installed in the molding cavity, feeds a refrigerant when the molding cavity is cooled, and is in a hollow state of not containing the refrigerant when the molding cavity is heated.
    • 本发明提供了一种成型模具及其控制方法,其目的是缩短从加热到模具的模腔的冷却的周期时间,其结构简单且便宜。 在具有模制基材的成型腔的成型模具中,将成型用的模具材料用于成型腔内,供给制冷剂的冷却装置沿着成型面安装在成型腔的内部,通过高频感应加热装置 安装在冷却装置周围,并且当基体材料用模制腔模制时,模制腔被加热装置和冷却装置重复地交替地加热和冷却。 这里,冷却装置包括安装在模制腔中的管状体,当模腔被冷却时供给制冷剂,并且当加热模制腔时处于不含制冷剂的中空状态。
