When the difference in the die temperature is large, the variables in the production cycle, such as filling time, cooling time, spraying time and the like, are affected to different degrees. In the use process of the existing die-casting die cooling structure, the cooling effect of the die-casting die is poor, so that the quality of produced products is uneven, the defective rate is high, and certain defects exist.

For this purpose, a cooling mechanism for a die casting mold is proposed.
