When there is a coolant in the ice storage box 7, the water flow in the water pipe 6 will also be affected and start to cool down. In this way, a set of cooling equipment can flexibly adjust the cooling temperature when facing molds with different cooling requirements.

When the gear 206 rotates, it will drive the two racks 204 above and below to extend to both sides respectively with the cooperation of the connecting rod 202. When the racks 204 extend to both sides, they drive the corresponding fixed bars 205 to move to both sides. After the racks 204 are extended, different mold tables 3 can be freely replaced. After the replacement, the turntable 207 is rotated in the opposite direction to make the racks 204 and the fixed bars 205 return to their original positions to continue to fix the mold table 3, thereby achieving the effect of quickly replacing different mold tables 3.
