Abstract
PURPOSE: To form a cooling duct in a free shape and moreover easily by forming a core to form a cooling duct using thermoplastic resin.
CONSTITUTION: In an outside position of an inside coil, a core 13 for a cooling duct mold out of thermoplastic resin such as acryl, vinyl chloride, which soften at about 150°C, will be provided. Next, these will be transferred in a metal mold 15 and then thermosetting mold resin 16 such as epoxy resin will be injected 17. After a heating and setting treatment, the metal mold 15 will be disassembled and a mold coil 18 will be treated for hardening at a higher temperature than that required for molding e.g. at 150°C to soften the core 13, which will be removed to form a cooling duct 5. By doing so, the cooling duct can easily be formed in a free shape with thermoplastic resin without generating strain when setting.
