AI Technical Summary
Existing mold cooling devices can only cool one side of the metal casting, resulting in a long cooling time and making it impossible to achieve rapid cooling and molding.
A lower bowl-shaped cooling cavity is set inside the lower mold, and an upper bowl-shaped cooling cavity is set inside the upper mold. Connecting holes are set at the top and bottom of both. The circulation of cold water between the lower and upper bowl-shaped cooling cavities is achieved through the opening and closing structure, realizing double-sided heat exchange of the metal casting.
The double-sided heat exchange significantly improves the cooling effect of metal castings, enabling them to cool and solidify rapidly, and automatically seals the docking holes when the mold is separated, preventing water from spilling out.
