Mold for rotary molding device, has heating resistive unit that is incorporated in thickness of internal wall of each half-cavity, where temperature of internal wall is raised so as to raise internal temperature of mold

摘要

The mold (1) has two half-cavities (2) that are independently attached together in a removable manner in a water-tight manner. Each of the two half-cavities is arranged with an internal wall (3), and a heating resistive unit is incorporated in a thickness of the internal wall of each half-cavity. Temperature of internal wall is raised so as to raise internal temperature of the mold. The heating resistive unit is arranged with a wire grid that is electrically conductive. Each of the cavities is provided as a hollow-envelope. An independent claim is also included for a rotary molding device.
