MOLD HEATING DEVICE AND METHOD OF HEATING MOLD PRELIMINARILY BY MOLD HEATING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a molding heating device which improves safety and can efficiently heat a fixed mold and a movable mold preliminarily and a method of heating a mold preliminarily by a mold heating device.SOLUTION: A mold heating device 1 is held by and arranged between a fixed mold and a movable mold before a molten material is injected into a cavity formed by clamping the fixed mold 40 and the movable mold 41 capable of approaching and separating from the fixed mold in such a way as to oppose the fixed mold and heats the fixed mold and the movable mold preliminarily. The mold heating device has a built-in IR heater 3 comprising a carbonaceous heat generator sealed in a glass tube, and the fixed mold and the movable mold are heated through irradiation with IR rays generated by electrifying the carbonaceous heat generator.
