When it is necessary to grind the front side of the mold, control the first electric push rod 3 and the hydraulic cylinder 14 to contract, control the second motor 17 to rotate forward. The second motor 17 drives the gear 18 to rotate. By using the meshing rotation of the gear 18 and the external gear ring 19, control the mold to flip backward. When the mold flips 90 degrees, stop the second motor 17. At this time, the original front side flips to the top surface, avoiding disassembling and assembling the mold and further improving the processing efficiency. During the grinding of the mold, control the water pump 25 to operate. The water pump 25 extracts the coolant and sprays it onto the grinding area of the mold to cool the mold in time, avoid the mold from becoming soft due to heat, and thus extend the service life of the mold.
