A cooling mold for casting is provided to prevent the decrease of cooling efficiency generated by local stagnation of the cooling water and to minimize the temperature rise of the inflow cooling water by dividing passages for a water inlet unit and a water outlet unit. A cooling mold(2) for casting has a pattern surface(8) formed at a head unit(4) and fitted and fixed while being exposed to a hollow part, and a cooling water passage. The cooling water passage comprises a cooling water inlet port(16); a first passage(10) extended toward the pattern surface along a body unit(6); a cooling water outlet port(18); a second passage(12) installed separately from the first passage; and a third passage(14) of which one side is connected to the first passage, curved in zigzag, and extended to turn around the head unit, and the other side is connected to the second passage. |
