Abstract
PURPOSE: To make it possible to improve heating efficiency irrespectively of the size of mold, by installing an antenna from the opening to the depth of metal mold filled with admixed sand, and by introducing a microwave into the depth.
CONSTITUTION: Insulating layer 2 made of heat resisting rubber, etc., is formed on the circumference of mold cavity 3 of metal mold 1 in which admixed sand for making mold 5 is filled up, and then antenna 4 is inserted from opening 6 of mold cavity 3. When a microwave is irradiated on opening 6 of metal mold 1, antenna 4 introduces the microwave into the depth of admixed sand for making mold 5, and the microwave heats the admixed sand for making mold 5 and harden it.
