The second cylinder 26 is fixedly installed on the right side of the vertical support 24. The output shaft of the second cylinder 26 is fixedly connected to the right side of the moving mold 25. The rear end of the extension frame 32 is fixedly installed on the front side wall of the moving mold 25.

[0038] When this utility model is in use, the output shaft of the second cylinder 26 moves to drive the moving mold 25 to move to the left on the vertical support 24. The moving mold 25 moves to the fixed mold 21 to close the mold and perform injection molding through the injection port. After the panel back cover is formed, the output shaft of the second cylinder 26 moves to drive the moving mold 25 to move to the right on the vertical support 24 and leave the fixed mold 21.

[0039] When the second cylinder 26 drives the moving mold 25 to leave the fixed mold 21, the moving mold 25 moves and drives the extension frame 32 to move to the right. The extension frame 32 moves and drives the rack 34 to move to the right within the slide block 33. The rack 34 moves and drives the gear 36 to rotate. The gear 36 rotates and drives the first bevel gear 37 to rotate. The first bevel gear 37 rotates and drives the second bevel gear 310 to rotate. The second bevel gear 310 rotates and drives the connecting rod 38 to rotate. The connecting rod 38 rotates and drives the rotating plate 39 to rotate. The rotating plate 39 rotates and drives the cleaning device 4 and the cooling device 5 to rotate between the fixed mold 21 and the moving mold 25. This utility model, through the mechanical linkage between the forming device 2 and the flipping device 3, enables cleaning and cooling to be performed simultaneously after demolding, which is beneficial for the simultaneous cleaning and cooling of the mold during demolding.

The sliding plate 45 is slidably connected to the inner side of the support plate 41, and the two moving wheels 46 are rotatably connected to the sliding plate 45 through a rotating shaft. The four fixed wheels 42 and the two moving wheels 46 are connected by a belt drive.

[0042] In use, the fixed wheel 42 is driven to rotate by the output shaft of the reduction motor 43. The rotation of the fixed wheel 42 drives the movable wheel 46 to move up and down while rotating. The sliding plate 45 is used to guide the up and down movement of the movable wheel 46.

[0043] In some embodiments, such as Figure 6As shown, the moving assembly also includes a rotating assembly, which is mounted on the axle of one of the moving wheels 46.

The axle of the fixed wheel 42 is rotatably connected to the support plate 41, and the axle of the moving wheel 46 is rotatably connected to the sliding plate 45.

[0044] In use, this invention utilizes the vertical movement and rotation of the movable wheel 46, which in turn drives the support plate 47 to move vertically and rotate simultaneously. The support plate 47, in turn, drives the cylinder 48 to move vertically and rotate simultaneously, which in turn drives the cleaning brush 49 to move vertically and rotate simultaneously. The cleaning brush 49 cleans the surfaces of the moving mold 25 and the fixed mold 21 vertically and rotates simultaneously. This invention employs a motor to drive the cleaning brush 49 to perform this vertical and rotational cleaning of the moving mold 25 and the fixed mold 21.
