[0050] As Figures 1 to 4As shown in the figure, a cleaning mechanism is arranged inside the frame 1 for cleaning the debris in the two molds 2. The cleaning mechanism includes: a cleaning box 4, a guide ring 5, a collection box 6, a cleaning component, a suction component, a moving component and a buffer component. Both of the two guide rings 5 are made of rubber, and a plurality of suction openings are respectively arranged inside the two guide rings 5. The cleaning box 4 is slidably arranged inside the frame 1, and the cleaning brush 3 is rotatably connected to the cleaning box 4. A plurality of suction openings are formed in the cleaning box 4. There are two guide rings 5, and the two guide rings 5 are respectively arranged at each adjacent plurality of suction openings. The collection box 6 is communicated with the cleaning box 4. The cleaning component is arranged on the cleaning box 4 for cleaning the debris. The suction component is arranged inside the collection box 6 for collecting the debris. The moving component is arranged on the frame 1 for driving the cleaning box 4 to move. The buffer component is arranged on the frame 1 for buffering the cleaning box 4. The cleaning component includes: a rotating wheel 7, a transmission belt 8 and a first motor 9. A stabilizing frame 20 is fixedly connected to the cleaning box 4, and the first motor 9 is installed on the stabilizing frame 20. There are two rotating wheels 7, one of the rotating wheels 7 is fixedly connected to the cleaning brush 3, and the other rotating wheel 7 is rotatably connected to the cleaning box 4. The transmission belt 8 is drivingly connected between the two rotating wheels 7. The first motor 9 is arranged on the cleaning box 4, and the output end of the first motor 9 is fixedly connected to one of the rotating wheels 7. The suction component includes: a filter plate 10 and a blower 11. The filter plate 10 is fixedly connected inside the collection box 6, and the blower 11 is arranged inside the collection box 6.

Specifically, the first electric cylinder 14 arranged on the support frame 13 drives the cleaning box 4 to move, so that the cleaning brush 3 on the cleaning box 4 moves between the two molds 2. Then the first motor 9 drives the rotating wheel 7 to rotate. When the rotating wheel 7 rotates, the cleaning brush 3 is driven to rotate through the transmission of the transmission belt 8. At this time, the two molds 2 approach each other, and the cleaning brush 3 is placed inside the two molds 2 and rotated, so as to sweep the debris inside the two molds 2. Then the guide ring 5 fits onto the mold 2, and the blower 11 inside the collection box 6 blows air, so that the debris is sucked into the collection box 6 through the suction openings and intercepted by the filter plate 10. When the upper mold 2 presses down, it drives the cleaning box 4 to move adaptively up and down,The cleaning box 4 is supported and buffered by a buffer spring 16, so that the cleaning box 4 moves adaptively following the approach of the two molds 2 to each other.

[0052] In this embodiment, when cleaning the two molds 2, the first electric cylinder 14 is started to drive the cleaning box 4 to move, so that the cleaning brush 3 on the cleaning box 4 moves between the two molds 2. Then, the first motor 9 drives the rotating wheel 7 to rotate. When the rotating wheel 7 rotates, the cleaning brush 3 is driven to rotate through the transmission of the transmission belt 8. At this time, the two molds 2 approach each other, and the cleaning brush 3 is placed inside the two molds 2 and rotated, so as to sweep the debris inside the two molds 2. Then, the guiding ring 5 fits onto the mold 2, and the blower 11 in the collection box 6 blows air, so that the debris is sucked into the collection box 6 through the air suction port, and the debris is intercepted by the filter plate 10. When the upper mold 2 presses down, it drives the cleaning box 4 to move up and down adaptively, and the cleaning box 4 is supported and buffered by the buffer spring 16, so that the cleaning box 4 moves adaptively following the approach of the two molds 2 to each other. After the cleaning is completed, the first electric cylinder 14 moves in the reverse direction, thereby driving the cleaning box 4 away from the two molds 2, and the hydraulic cylinder 18 is started to drive the mold 2 to continue the cold heading operation.

[0053] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
