The card ball 11 is slidably connected with the limiting hole 8, and the output shaft is driven to rotate by the motor 16 to drive the gear 2 7 to rotate. Under the meshing relationship, the gear 2 7 can drive the gear 1 5 to rotate, and then drive the rotating column 4 to rotate. In this process, when the rotating column 4 rotates, the inner wall of the limiting hole 8 squeezes the card ball 11, and the card ball 11 pushes the elastic sheet 10 to deform, and finally makes the card ball 11 disengage from the limiting hole 8. Under the action of force, the card ball 11 slides along the surface of the rotating column 4. When the card ball 11 slides into the next limiting hole 8, the elastic sheet 10 restores its deformation to push the card ball 11 to insert into the limiting hole 8, so as to refine the position of the rotating column 4.

[0023] See also Figure 1 , Figure 2 , Figure 3 , Figure 5, a chip removal mechanism 12 is provided on the rotating column 4, and the chip removal mechanism 12 includes a slide groove 121. The horizontal part of the rotating column 4 is provided with a slide groove 121, and a slide plate 122 is slidably connected to the inner wall of the slide groove 121. A high-pressure fan 1221 is fixedly installed at the lower end of the slide plate 122, and a limit ring 123 is fixedly sleeved on the outer side of the slide plate 122. The limit ring 123 is slidably connected to the horizontal part of the rotating column 4, and a fixed plate 124 is fixedly connected to the horizontal part of the rotating column 4. A spring 125 is welded to the right end of the fixed plate 124, and the other end of the spring 125 is welded to the slide plate 122. Through the setting of the spring 125, the slide plate 122 can be connected and used, and a motor 126 is fixedly installed on the vertical part of the rotating column 4.

[0024] The specific implementation process of the utility model is as follows: when it is necessary to use the die-casting mold with a chip removal function, start the motor 16 to drive the output shaft to rotate, so as to drive the gear 2 7 to rotate. Under the meshing relationship, the gear 2 7 can drive the gear 15 to rotate, and then drive the rotating column 4 to rotate, so as to drive the high-pressure fan 1221 to rotate, so that the high-pressure fan 1221 is located above the die-casting lower mold 2 after the mold is opened. In this process, when the rotating column 4 rotates, the inner wall of the limiting hole 8 squeezes the card ball 11, and the card ball 11 pushes the elastic sheet 10 to deform, and finally makes the card ball 11 disengage from the limiting hole 8. Under the action of force, the card ball 11 slides along the surface of the rotating column 4. When the card ball 11 slides into the next limiting hole 8, the elastic sheet 10 restores the deformation to push the card ball 11 to insert into the limiting hole 8, limit the rotating column 4, and then refine the position of the high-pressure fan 1221.

Start the motor 2 126 to drive the output end to rotate, so as to drive the winding wheel 127 to rotate, and then reel the traction line 128. Under the action of the guide column 129, the traction line 128 can be guided, and then the slide plate 122 can be pulled to move. Under the action of the limit ring 123, the movement of the slide plate 122 is ensured to be stable, and the spring 125 is deformed. When the slide plate 122 moves, it drives the high-pressure fan 1221 to move, and the position of the high-pressure fan 1221 is adjusted to improve the blowing and chip removal effect of the high-pressure fan 1221.
