During the movement, the sponge brush 32 first brushes the upper surface of the lower mold plate 1, and then the high-speed airflow sprayed by the spray head 35 blows the debris away from the surface of the lower mold plate 1, so that the debris on the surface of the lower mold plate 1 is accurately cleaned. The cleaning mechanism 3 further comprises a rotating block 36, an extension rod 37 and a limiting spring 38. The extension rods 37 are respectively located at the front and rear sides of the door-shaped frame 31. The extension ends and the fixed ends of the extension rods 37 are provided with the rotating blocks 36. The lower rotating blocks 36 are rotatably connected to the vertical plates of the door-shaped frame 31 through rotating shafts I.

The limiting springs 38 are arranged between the two rotating blocks 36 on the same extension rod 37. The limiting springs 38 are movably sleeved on the outer arc surfaces of the extension rods 37. When the rotating plates 33 rotate relative to the door-shaped frame 31, the elastic force of the limiting springs 38 is overcome, so that the extension rods 37 are retracted. Through the rotary connection of the rotating blocks 36, the angle of the extension rods 37 is changed. When the extension rods 37 are rotated to the vertical state, the extension rods 37 are elongated with the continuous movement of the blowing pipe 34. Under the elastic force of the limiting springs 38, the relative close force of the blowing pipe 34 and the door-shaped frame 31 is increased, so that the positions of the blowing pipe 34 and the door-shaped frame 31 are limited. The horizontal plate surfaces of the door-shaped frame 31 are respectively provided with sliding grooves 4. The sliding grooves 4 are vertically and slidingly connected with sliding columns 6.

Since the two adjusting frames 7 are vertically slidably connected with the blowing pipe 34, the rotation of the adjusting frames 7 is limited. Through the threaded connection between the adjusting frames 7 and the screw rods 8, the two adjusting frames 7 drive the blowing pipe 34 to move left and right. The upper surface of the horizontal plate of the door-shaped frame 31 is provided with a rubber pad 13. The two rotating plates 33 are provided with photoelectric sensors 12 in the mounting holes on the opposite inner side surfaces of the upper end.

When the photoelectric sensor 12 receives the reflected light, the external controller controls the motor 14 to stop. At this time, the blowing pipe 34 is located directly above the door-shaped frame 31. The lower surface of the blowing pipe 34 is in contact with the rubber pad 13. The rubber pad 13 seals the air outlet of the nozzle 35, blocks the ejection of the airflow, and stops blowing. The upper surface of the lower mold plate 1 is provided with guide columns 15 at the front and rear ends. The door-shaped frame 31 is provided with guide sliding blocks 16 at the cylindrical ends of the front and rear sides. The guide sliding blocks 16 are respectively transversely slidably connected with the adjacent guide columns 15.
