<P>PROBLEM TO BE SOLVED: To provide a casting mold in which production of burrs can be suppressed. <P>SOLUTION: In the casting mold including degassing runners, in the case when a plurality of degassing runners 11, 12, 13, 14 are joined, the cross-sectional areas of the degassing runners 15, 16 after the joining are made smaller than the total of the cross-sectional areas of the respective degassing runners 11, 12, 13, 14 before the joining. The cross-sectional areas of the degassing runners 15, 16 after the joining decided by depth and width are set by adjusting the width while fixedly retaining the depth. The cross-sectional areas of the degassing runners 15, 16 after the joining are preferably 0.6 to 0.9 time the total of the cross-sectional areas of the respective degassing runners 11, 12, 13, 14 before the joining. <P>COPYRIGHT: (C)2012,JPO&INPIT |
