<P>PROBLEM TO BE SOLVED: To provide a structure for branching a runner with which flowing-in timing of molten metal into the plurality of runners after branching, can be adjusted more reliably than the conventional one, and a metallic mold for casting, having such runner branching structure. <P>SOLUTION: The runner branching structure is provided with the runner 101 before branching, the plurality of runners 102,103 after branching, branched from the runner 101 before branching and a molten metal basin 150 for adjusting the flowing-in timing of the molten metal into the plurality of runners 102,103 after branching. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
