[0027] The positioning structure includes a rotating shaft 31, one end of the rotating shaft 31 is rotatably mounted on the supporting plate 3, and the other end of the rotating shaft 31 is rotatably mounted on the inner wall of the cleaning box 1. A movable frame 32 is fixedly mounted on the rotating shaft 31, and a plurality of linkage toothed discs 33 are rotatably mounted on the top side of the movable frame 32. A fixing plate 34 is fixedly mounted on the linkage toothed disc 33, and two mounting seats 35 are symmetrically fixedly mounted on the linkage toothed disc 33. Screw rods 36 are threadedly mounted on the two mounting seats 35, and a stop block 37 is fixedly mounted on the ends of the two screw rods 36 that are close to each other. The injection mold to be cleaned is unfolded and placed On both sides of the fixed plate 34, the two screw rods 36 are then rotated so that the blocks 37 on both sides can be fixed against the two sides of the fixed plate 34. When in use, the cleaning liquid and water are respectively added to the liquid storage tank 26, and then the motor 44 and the corresponding water pump 25 are turned on. The water pump 25 can draw the cleaning agent from the liquid storage tank 26, and finally spray it onto the fixed oil spray mold through the nozzle 23 to rinse the oil spray mold. In the process, under the action of the motor 44, the oil spray mold can make a circular motion and rotate at the same time, so that the cleaning agent can be evenly sprayed on the oil spray mold to improve the cleaning effect.

[0028] In order to make the cleaning agent spray evenly on the oil injection mold, the driving structure includes a belt 41, which is transmission-mounted on the first pulley 4, and the first pulley 4 is fixedly mounted on one end of the rotating shaft 31. The second pulley 42 is transmission-mounted on the belt 41, and a support frame 43 is fixedly mounted on the top side of the liquid storage tank 26. A motor 44 is fixedly mounted on the top side of the support frame 43. The output end of the motor 44 passes through the support frame 43 and is fixedly mounted on one side of the second pulley 42. When the motor 44 is turned on, the output end of the motor 44 will drive the second pulley 42 to rotate. Under the rotation of the second pulley 42, the first pulley 4 will be driven to rotate by cooperating with the belt 41. The rotating first pulley 4 will drive the rotating shaft 31 to rotate, and the continuously rotating rotating shaft 31 will drive the movable frame 32 to move in a circle, so that the movable frame 32 in a circular motion drives the linked toothed disc 33 to move in a circle.

The linkage gear disc 33 will rotate by meshing with the internal threaded gear ring 45 during the circular motion.

[0033] The working principle is as follows: when in use, the oil spray mold that needs to be cleaned can be unfolded and placed on both sides of the fixed plate 34, and then the two screw rods 36 are rotated. When the screw rods 36 rotate, they will rotate and move in the threaded holes 38, so that the movable screw rods 36 will drive the abutment blocks 37 to move, so that the abutment blocks 37 on both sides can abut on both sides of the fixed plate 34 to fix the position of the fixed plate 34.

The output end of the motor 44 will drive the second pulley 42 to rotate, and the rotating second pulley 42 will drive the rotating roller 5 to rotate. During the rotation of the rotating roller 5, the stirring rod 51 will be driven to stir the water and the cleaning liquid in the liquid storage tank 26, so that the water and the cleaning liquid are evenly mixed. The remaining features are the same as those in Example 1.
