[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] As Figures 1 - 6 shown, a cleaning device for a hub mold includes a rotating platform 1, a rotating motor 2 is arranged below the rotating platform 1, and the rotating motor 2 is drivingly connected to the rotating platform 1; it further includes a lifting mechanism, the lifting mechanism includes a support rod 3, the upper end of the support rod 3 is connected to a top plate 4, a lifting cylinder 5 is arranged on the upper part of the top plate 4, the piston rod of the lifting cylinder 5 is arranged downward, the lower end of the piston rod of the lifting cylinder 5 passes through the top plate 4 and is connected to a lifting plate 6, a dry ice supply device 7 is installed on the lifting plate 6, a discharge pipe 8 is connected to the dry ice supply device 7, a guide frame 13 is arranged below the dry ice supply device 7, the discharge pipe 8 is installed in the guide frame 13, an extension plate 27 is installed at one end of the guide frame 13 away from the dry ice supply device 7, the discharge pipe 8 is integrally L-shaped, and the discharge pipe 8 can move in the guide frame 13.

[0025] Place the mold 32 to be cleaned on the rotating platform 1, and drive the lifting plate 6 to descend through the lifting cylinder 5, so that the lower part of the discharge pipe 8 enters the cavity of the mold 32. A part of the discharge pipe 8 is arranged close to the inner side wall and bottom surface of the mold 32, and the dry ice particles generated by the discharge pipe 8 are sprayed out at high speed through the discharge pipe 8. The dry ice particles impact the inside of the mold 32 at high speed, causing the dirt and residues to burst and fall off instantly, and can quickly and thoroughly remove the dirt and residues inside the mold 32.

[0026] The rotating motor 2 drives the rotating platform 1 to rotate, and the rotating platform 1 drives the mold 32 to rotate, so that the dry ice particles can cover the entire inside of the mold 32, thereby ensuring the integrity of the cleaning.

[0027] For the mold 32 with a larger forming cavity, pull out the extension plate 27 from the guide frame 13 so that the end of the extension plate 27 reaches or slightly exceeds the center of the forming cavity. By moving the discharge pipe 8, the end of the discharge pipe 8 reaches the extended extension plate 27. In this way, when the mold 32 rotates, the dry ice particles sprayed out from the discharge pipe 8 can cover the entire bottom surface of the forming cavity, and there is no need to adjust the position of the discharge pipe 8 or the mold 32 for secondary supplementary cleaning.

[0028] The support rod 3 is arranged through the lifting plate 6. The support rod 3 guides the lifting of the lifting plate 6 to ensure the vertical movement of the lifting plate 6 and avoid the deviation of the lifting plate 6, which may cause the deviation of the discharge pipe 8 and affect the cleaning effect.

[0029] A number of clamps are arranged on the upper part of the rotating platform 1. The clamp includes a support seat 9 installed on the upper part of the rotating platform 1. A threaded seat 10 is installed on the support seat 9. An adjusting screw rod 11 is connected to the threaded seat 10 by internal threads. The adjusting screw rod 11 is arranged through the support seat 9. A clamping block 12 is rotatably arranged at the inner end of the adjusting screw rod 11. By rotating the adjusting screw rod 11, the clamping block 12 is adjusted to approach and press against the mold 32. The combined action of a number of clamping blocks 12 clamps and fixes the mold 32 to avoid the deviation of the mold 32 during the rotation of the rotating platform 1, which may affect the cleaning effect.

[0030] As Figure 2 、 Figure 3 shown, the discharge pipe 8 includes a telescopic pipe 15 connected to the dry ice supply device 7. The lower part of the telescopic pipe 15 is connected with an extension pipe 16. The lower part of the extension pipe 16 is sequentially connected with a discharge section 17 and a telescopic section 18. The end of the lowermost discharge section 17 is hermetically arranged. A discharge port 19 is arranged at the middle position on the inner side of the discharge section 17. By moving the extension pipe 16, the lower discharge section 17 and the telescopic section 18 are driven to move along the guide frame 13, so as to complete the adjustment of the position of the discharge pipe 8. A telescopic pipe 15 is arranged between the extension pipe 16 and the dry ice supply device 7, which can expand and contract with the movement of the extension pipe 16 to maintain the sealed connection between the extension pipe 16 and the dry ice supply device 7.

[0031] Due to the arrangement of the telescopic section 18, the distance between two adjacent discharge sections 17 can be changed. At the same time, the telescopic section 18 can be deformed into an arc shape, so that the discharge section 17 can smoothly move in the guide frame 13 and be arranged along the guide frame 13.

[0032] In order to leave enough adjustment space, the number of the discharge sections 17 is set to be relatively large. Some discharge sections 17 are located outside the forming cavity of the mold 32. Sealing caps 20 are inserted into the discharge ports 19 of these discharge sections 17 to avoid the waste caused by the ejection of dry ice particles from the discharge ports 19 of these discharge sections 17.

[0033] As Figure 3 shown, the discharge port 19 is conical, and the diameter of the outer end of the discharge port 19 is larger than that of the inner end, so that the dry ice particles ejected from the discharge port 19 can cover a larger range and make up for the range missing due to the telescopic section 18 arranged between two discharge sections 17.

[0034] As Figure 4 、 Figure 5As shown in the figure, the guide frame 13 includes two parallel guide plates 31. There is a gap between the lower ends of the two guide plates 31 for the discharge port 19 to be exposed, without affecting the spraying of dry ice particles into the interior of the mold 32. The guide plate 31 includes a vertical section 21. The lower end of the vertical section 21 is connected with a transition section 22. One end of the transition section 22 far from the vertical section 21 is connected with a horizontal section 23. Guide notches 24 are provided on the vertical section 21, the transition section 22, and the horizontal section 23. The outer periphery of the discharge section 17 is connected with a first fixing screw 25, and the first fixing screw 25 passes through the guide notch 24 and is arranged.

[0035] The discharge section 17 located within the vertical section 21 corresponds to cleaning the vertical inner wall of the forming cavity of the mold 32. The discharge section 17 located within the horizontal section 23 corresponds to cleaning the bottom surface of the forming cavity of the mold 32. The discharge section 17 located within the transition section 22 is inclined and corresponds to cleaning the connection between the vertical inner wall and the bottom surface of the forming cavity of the mold 32. Preferably, the discharge section 17 located within the transition section 22 is arranged at 45°, so that the discharge port 19 on this discharge section 17 is directly opposite to the connection between the vertical inner wall and the bottom surface of the forming cavity, avoiding the omission of cleaning at the corner.

[0036] Through the arrangement of the guide notch 24, the movement of the discharge section 17 within the guide frame 13 can be guided. At the same time, the position of the discharge section 17 within the guide frame 13 can be fixed through the cooperation of the nut and the first fixing screw 25, ensuring that one of the discharge sections 17 is located at the position of the transition section 22. At the same time, the discharge sections 17 can be adjusted to be evenly arranged within the vertical section 21 and the horizontal section 23, avoiding the generation of cleaning blind areas due to the excessive distance between the two discharge sections 17.

[0037] The transition section 22 is arc-shaped, so that the discharge section 17 can smoothly enter from the vertical section 21 to the horizontal section 23.

[0038] A reinforcing rib 26 is connected between the vertical section 21 and the horizontal section 23 to ensure the stability of the horizontal section 23.

[0039] A telescopic groove 30 is provided within the horizontal section 23. The extension plate 27 is arranged within the telescopic groove 30. An opening 29 is provided on the outer periphery of the horizontal section 23, and the opening 29 is communicated with the telescopic groove 30. The right end of the opening 29 is communicated with the right end of the horizontal section 23. The outer periphery of the extension plate 27 is connected with a second fixing screw 28, and the second fixing screw 28 passes through the opening 29 and is arranged. The extension plate 27 can move along the telescopic groove 30, thereby adjusting the extending length of the extension plate 27 from the horizontal section 23. The position of the extension plate 27 is fixed through the cooperation of the nut and the second fixing screw 28.

[0040] A limiting plate 14 is connected to the right end of the extension plate 27, and the end position of the discharge section 17 is limited through the limiting plate 14.

[0041] For the mold 32 with a smaller forming cavity, the lower discharging section 17 and the telescopic section 18 can be pulled through the extension pipe 16, so that the end of the rightmost discharging section 17 in the horizontal section 23 corresponds to the center position of the forming cavity. The repeated cleaning of the middle area at the bottom of the forming cavity of the mold 32 can be reduced, and waste can be reduced.

[0042] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
