[0037] First, water is poured into water tank 11. Then, motor 2 54 is turned on, providing power to drive gear pump 52, which pumps water from water tank 11 into pipe 3 58. Simultaneously, hydrocyclone separator 62 automatically collects some of the abrasive debris carried in the water into collection box 63, reducing the abrasive debris content in the water. Nozzle 59 sprays water from pipe 3 58 onto the surface of grinding belt 50, thereby cooling grinding belt 50 and mold during grinding. Then, the mold is placed on support 1 13. Next, screw 21 is rotated, causing clamping plate 24 to move back and forth. Clamping plate 24 moves backward to clamp the mold. The handwheel 23 is used to clamp the lead screw 21. Then, the motor 34, cylinder 41 and cylinder 45 are turned on. The motor 34 provides power to drive the rotating shaft 31 to rotate and drive the grinding belt 50 to move. The cylinder 41 provides power to drive the rotating shaft 44 to move up and down. The cylinder 45 provides power to drive the rotating shaft 48 to move up and down, which tensions the grinding belt 50. The rotating shaft 31, cylinder 41 and cylinder 45 work together to drive the grinding belt 50 to be tensioned and moved to grind the mold. The grinding debris generated by grinding flows into the water tank 11 with the water. At this time, the magnetic roller 51 uses its own magnetism to attract and collect the grinding debris in the water.

[0038] like Figures 1 to 10As shown, this utility model discloses a mold cutting pretreatment device. During operation, water is first poured into the water tank 11. Then, motor 2 54 is turned on, providing power to drive gear pump 52, which pumps water from the water tank 11 into pipe 3 58. Simultaneously, cyclone separator 62 automatically collects some of the abrasive particles carried in the water into collection box 63, reducing the abrasive particle content. Nozzle 59 sprays water from pipe 3 58 onto the surface of grinding belt 50, thereby cooling the grinding belt 50 and the mold during grinding. The mold is then placed on support 1 13, and screw 21 is rotated, causing clamping plate 24 to move back and forth. The clamping plate 24 moves backward to clamp the mold, and the handwheel 23 facilitates clamping the lead screw 21. Then, the motor 34, cylinder 41, and cylinder 45 are turned on. The motor 34 provides power to drive the rotating shaft 31 to rotate and drive the grinding belt 50 to move. The cylinder 41 provides power to drive the rotating shaft 44 to move up and down. The cylinder 45 provides power to drive the rotating shaft 48 to move up and down and to tension the grinding belt 50. The rotating shaft 31, cylinder 41, and cylinder 45 work together to drive the grinding belt 50 to tension and move to grind the mold. The grinding debris generated by grinding flows into the water tank 11 with the water. At this time, the magnetic roller 51 uses its own magnetism to attract and collect the grinding debris in the water.

[0039] The lead screw 21, motor 34, cylinder 41, two cylinders 45, grinding belt 50, gear pump 52, motor 54, multiple nozzles 59 and cyclone separator 62 of this utility model are purchased from the market. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0040] The main functions achieved by this utility model are: by setting up a chip removal and cooling device 05, water is sprayed to cool the machine and the mold, preventing the mold from overheating and improving the mold quality; and by setting up a grinding device 04, the contact area between the grinding head and the mold is increased, preventing uneven heating of the mold and improving the mold quality. This solves the existing technical problems that the existing machine uses dry grinding to rough grind the mold, which easily causes the mold to overheat and results in poor mold quality, and the existing machine uses a small contact area between the grinding head and the mold, which makes the mold easy to heat unevenly during grinding, resulting in poor mold quality.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
