A slide groove 10 is provided, and a slider 11 adapted to the slide groove 10 is fixed on the moving block 14. The slider 11 is slidably connected to the slide groove 10. Under the action of the slider 11 and the slide groove 10, the moving block 14 can only move in the horizontal direction. A screw rod 7 runs through the moving block 14, and a motor 13 for driving the screw rod 7 to rotate is installed on the moving plate 8. The screw rod 7 is screwed and connected to the moving block 14 through a thread, and both ends of the screw rod 7 are rotatably connected to the moving plate 8 through bearings. The output end of the motor 13 is fixed to the screw rod 7. During the process of the motor 13 driving the screw rod 7 to rotate, the moving block 14 can move along the axial direction of the screw rod 7; The moving block 14 is provided with a gear 17 and an air nozzle 18 via a connecting shaft 19. The moving block 14 has a cavity, in which the gear 17 and the air nozzle 18 are placed. The connecting shaft 19 passes through the cavity and is rotationally connected to the moving block 14. The connecting shaft 19 is fixedly connected to the gear 17 and the air nozzle 18. The air nozzle 18 is connected to an air pump 15 fixed to the moving block 14 via a hose 27. The air pump 15 is placed above the moving block 14. During the operation of the air pump 15, the airflow can enter the air nozzle 18 via the hose 27, and then be ejected through the air nozzle 18. The setting of the hose 27 (flexible material) allows the air nozzle 18 to rotate while ensuring the normal flow of the airflow. A toothed plate 16 is installed on the outer side of the moving block 14. The toothed plate 16 and the moving block 14 can be slidably connected via a guide rail. The toothed plate 16 is used to move in the vertical direction. The inner side of the toothed plate 16 has a continuous latching tooth, which is meshed with the gear 17. During the movement of the toothed plate 16, under the action of the meshing of the gear 17 and the latching tooth, the gear 17 can drive the connecting shaft 19 and the air nozzle 18 to rotate accordingly. The end of the tooth plate 16 is rotatably connected with a pressure cover 32, and the pressure cover 32 and the tooth plate 16 are connected through a rotating shaft. A rotating block 23 is arranged inside the pressure cover 32, and the rotating block 23 is arranged in a circular shape. The pressure cover 32 and the rotating block 23 are rotatably matched, and the rotating block 23 has a strip groove 22. The pressure cover 32 and the tooth plate 16 are fixed by a positioning component. A turntable 25 is installed at the bottom of the moving block 14, and a movable cavity 31 is provided on the turntable 25, and a rotating pin 26 matching the strip groove 22 is installed in the movable cavity 31 through the positioning component 2, and the rotating pin 26 and the turntable 25 are eccentrically arranged, and the rotating pin 26 is a cylindrical structure, and the diameter of the rotating pin 26 is equal to the groove width of the strip groove 22. When the strip groove 22 is in a horizontal state, the rotating pin 26 follows the rotation of the turntable 25, and the rotating pin 26 acts on the inner wall of the strip groove 22, so that the tooth plate 16 can reciprocate in the vertical direction; Electric push rods 29 are fixed to the inner walls on both sides of the movable plate 8. The telescopic ends of the electric push rods 29 are installed with abutment plates 12 in contact with the turntable 25. The electric push rods 29 are used to drive the abutment plates 12 to move in the vertical direction. When the abutment plates 12 are separated from the turntable 25, the friction between the abutment plates 12 and the turntable 25 disappears. As the movable block 14 moves, the turntable 25 will not rotate, thereby achieving blowing in a fixed direction.

[0019] Specifically, Figure 3 As shown, the first positioning assembly includes a rotating arm 20 mounted on the tooth plate 16, the rotating arm 20 and the tooth plate 16 are connected by a rotating shaft, the rotating arm 20 abuts against the pressure cover 32 in a vertical state, and the rotating arm 20 and the pressure cover 32 are in a flush state. In this state, the rotating arm 20 cannot rotate around the rotating shaft, so as to fix the pressure cover 32; A locking bolt 21 passes through the rotating arm 20, and a threaded hole connected to the locking bolt 21 is provided on the rotating block 23. When the locking bolt 21 is screwed into the threaded hole, the movement trajectory of the rotating block 23 and the rotating arm 20 conflicts, thereby achieving the fixation of the rotating arm 20 and the rotating block 23. In this state, the strip groove 22 is horizontally distributed.

[0020] Specifically, Figure 4 and Figure 5 As shown, the second positioning component includes a positioning block 29 arranged in the movable cavity 31 and fixed to the rotating pin 26, and a sliding rod 33 passing through the positioning block 29. The sliding rod 33 is distributed along the radial direction of the turntable 25, and the sliding rod 33 is fixedly connected to the inner wall of the movable cavity 31, and the positioning block 29 and the sliding rod 33 are slidably connected. Steps 34 are formed on the inner walls of both sides of the movable cavity 31, and a locking bolt 20 abutting against the step 34 is screwed on the positioning block 29. When the locking bolt 20 is tightened, the end of the locking bolt 20 abuts against the step 34. Under the action of the friction between the locking bolt 20 and the step 34, the positioning of the positioning block 29 and the rotating pin 26 is completed. The rotating pin 26 can be used to adjust the travel distance of the tooth plate 16 when it is in different positions. When the travel distance of the tooth plate 16 changes, it can be used to adjust the rotation angle of the air nozzle 18, which can meet the dust removal requirements of mold seats of different specifications and has stronger adaptability.

[0021] Specifically, Figure 3As shown, a protrusion 24 is formed on the rotating block 23, and the protrusion 24 provides a force point for the staff. The protrusion 24 can facilitate the staff to rotate the rotating block 23. When the strip groove 22 rotates to a vertical state following the rotating block 23, the pressure cover 32 is flipped upward, and there is no interference between the inner wall of the strip groove 22 and the rotating pin 26, so as to facilitate the normal flipping of the pressure cover 32. After the pressure cover 32 is flipped, the positioning block 29, the step 34 and the locking bolt 30 in the movable cavity 31 are exposed, which is convenient for the staff to adjust the position of the rotating pin 26.

[0022] Specifically, Figure 3 and Figure 4 As shown, a rubber nozzle 28 is installed at the air outlet end of the air nozzle 18. The rubber nozzle 28 is made of a flexible material. The staff can adjust the initial air outlet angle through the rubber nozzle 28 to meet different usage requirements.

[0023] In summary, when the mold cavity of the lower mold base needs to be cleaned, the electric push rod 2 and the air pump 15 are turned on, and the electric push rod 2 drives the sliding sleeve 6 and the movable plate 8 to move in the vertical direction, and the movable plate 8 is adjusted to a suitable height, and then the motor 13 is turned on, and the screw rod 7 rotates following the output end of the motor 13, and the moving block 14 is screwed with the screw rod 7, so the moving block 14 moves along the axial direction of the screw rod 7; The turntable 25 and the abutment plate 12 are in contact. Under the action of the friction between the two, the turntable 25 drives the rotating pin 26 to rotate during the movement of the moving block 14. The rotating pin 26 and the turntable 25 are eccentrically arranged. The rotating pin 26 acts on the inner wall of the strip groove 22, so that the tooth plate 16 makes a reciprocating motion in the vertical direction. Under the action of the meshing of the tooth plate 16 and the gear 17, the connecting shaft 19 drives the air nozzle 18 to swing back and forth. The airflow generated by the air pump 15 enters the air nozzle 18 through the hose 27, and then acts on the mold cavity of the lower mold base through the rubber nozzle 28, thereby realizing automatic cleaning of foreign matter such as dust. Compared with the operation mode of the dust removal mechanism held by the staff in the prior art, the degree of automation is higher, which reduces the workload of the staff. When facing lower die seats of different specifications and need to adjust the swing amplitude of the air nozzle 18, unscrew the locking bolt 21. In this state, the limit of the rotating arm 20 and the rotating block 23 is released, and the protrusion 24 acts on the rotating block 23 to rotate the strip groove 22 from horizontal to vertical, and then flip the pressure cover 32 upward. In this state, the positioning block 29 and the locking bolt 30 are exposed. After loosening the locking bolt 30, the positioning block 29 can be moved along the axial direction of the slide rod 33. After adjusting the positioning block 29 to the required position, tighten the locking bolt 30 again. Under the action of the abutment between the end of the locking bolt 30 and the step 34, the positioning block 29 and the rotating pin 26 are re-positioned. Finally, the rotating block 23, the pressure cover 32 and the locking bolt 21 are reset to complete the entire adjustment process.
