Abstract

PURPOSE: To enable to keep at a proper temperature with a high thermal efficiency by a means wherein heating bodies such as electric heaters or the like are provided in surface layers of a forming mold jig and only necessary portions thereof are enabled to be heated.
CONSTITUTION: Electric heaters 7 are provided in surface layers of an outer jig 1 and an inner mold 2, and are fed. The surface layers of the outer jig 1 and the inner mold 2 as well as an outer box 3 and an inner box 4, contacting with the inner layers thereof, may be heated quickly and efficiently by the heaters, further, may be kept at a proper temperature easily by a means wherein surface temperatures of the jig and the mold are detected and circuits for the electric heaters 7 are closed or opened. If desired, heat medium may be sealed and circulated within tanks 8 and pipings 9 provided for the inner mold 2, or heat rays may be projected against an inner surface of the inner mold 2 by a projector 10 of heat rays such as far infrared rays or the like provided within the inner mold 2.
