PURPOSE: A casting mold for forming cookers by electromagnetic induction heating method is provided to produce a more ideal product by integrally forming a magnetic metal sheet at the bottom center of a bottom part of the cookers without bending. CONSTITUTION: The casting mold(100) is characterized in that a plurality of suction holes(311) are perforated on a bottom part(310) of lower mold(300), and the suction holes are connected to vacuum pump(338) through connection pipe(335) and vacuum valve(336) so that a magnetic metal sheet(320) rested on the bottom part of the lower mold is adsorbed onto thus fixed to the bottom part by suction force through the suction holes, wherein position fixing projecting pins(337) are projected from both sides of the bottom part of the lower mold in such a way that the position fixing projecting pins appeare and disappear, wherein a depressed part is formed on an upper surface of support(330) installed under the bottom part of the lower mold to result in formation of a space part(333) so that the suction holes perforated on the bottom part are communicated with each other through the space part, and wherein a plurality of magnets are installed between the suction holes formed on the bottom part of the lower mold, and a cooling hole is formed in the support positioned under the bottom part of the lower mold so that cooling water is circulated through the cooling hole.
