Mold water cooling device, annular water cooling disc and casting mold water cooling system

The utility model belongs to the technical field of casting water cooling. The utility model provides a mold water cooling device, an annular water cooling disc and a casting mold water cooling system. The distance from the water inlet of the water cooling channel to the cooling surface is greater than that from the water outlet of the water cooling channel to the cooling surface; the distance between the water cooling channel and the cooling surface is uniformly changed from top to bottom; therefore, the water temperature difference of the cooling water in the process of flowing through the water cooling channel is small, the casting in the casting mold is uniformly cooled, the cooling uniformity of the casting can be effectively improved, and the possibility of casting shrinkage porosityor casting stress cracks caused by non-uniform cooling is reduced, so that the yield of cast products is effectively improved. 本实用新型属于铸造水冷技术领域，提供了一种模具水冷装置、环形水冷盘及铸造模具水冷却系统，设置水冷通道在进水口处距离冷却面的距离大于水冷通道在出水口处距离冷却面的距离，并且水冷通道距离冷却面的距离
