Abstract

This invention relates to a retractable device for a high frequency preheating mold. The retractable device is constituted by a heat coils movable relative to the male mold and female mold on a device body providing electric power and coolant. A cradle extends out of the device body and is provided for disposition of a retractable cylinder thereon. The retractable cylinder consists of a cylinder body and a retractable rod and protrudes or retracts the rod for a long or shot distance by utilizing the method of pneumatics or hydraulics. The device body is disposed with power supply wires, a coolant pipes and thermal conductive coils heated by using the high frequency Induction. By driving of the retractable cylinder's opeartion, the thermal conductive coils are moved by a predetermined distance, and the power supply wires are moved with the retractable rod. Thus, the male and female molds are preheated while the mold is shifted corresponding to the machine to be heated.
