The above patent extracts cooling water from the water tank through the water pump, transports it to the diverter pipe through the pumping pipe, and then sprays it out from the nozzle, so as to spray and cool the mold placed on the top of the placement plate, and the cooling water after spraying flows out from the circular hole in the placement plate, is filtered through the filter net, and then discharged into the water tank, thereby achieving the effect of recycling cooling water and avoiding the waste of cooling water.
