Casting mold for copper alloy pump shell of large ocean ship

The utility model discloses a large-scale ocean ship copper alloy pump shell casting mold, which relates to the technical field of mold manufacturing, and is characterized in that water is injected into a water cooling bin through a water inlet hole, the injected water is used for dissipating heat on the surfaces of a first casting mold bin and a second casting mold bin, and the water in the water cooling bin flows out of the water cooling bin through a water outlet hole; therefore, the water in the water cooling bin always keeps flowability, and the heat dissipation effect can be higher; meanwhile, cold air is injected into a heat dissipation channel through a first draught fan and a second draught fan, air cooling heat dissipation is conducted on the surfaces of the sides, away from the cold water bin, of the first casting mold bin and the second casting mold bin through the cold air, the situation that in the casting process, the temperature difference in the first casting mold bin and the second casting m
