[0002] Rubber dust cover is a widely used functional part. Due to its large quantity and variety, it is now mostly produced in multi-cavity mass production mode. When demolding and taking out the product, the worker needs to stand in front of the mold core to take out the product. After taking out one side, the mold core needs to be rotated to take out the product behind, and then the mold core needs to be turned over again to return to its original position; the product on the other side needs to repeat the same action to complete the work.

[0003] Traditional molds have the following disadvantages: the mold core needs to be flipped four times on both the front and back sides to complete the work, and there is a risk that the worker will forget to flip the mold core back into place, which can easily cause the mold core to be crushed when the mold is closed; the mold cores are numerous and heavy, making it difficult to flip them, and the workers are very labor-intensive.

[0007] As a preferred technical solution, the rotating part includes a large gear, and the linkage part includes a rack and a rotating wheel. Both sets of racks are meshed and connected with the large gear, and the end of the rack away from the large gear is meshed and connected with the rotating wheel.

[0021] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0022] Example 1

[0023] refer to Figures 1 to 5 The dust cover mold core flipping mechanism described in this embodiment includes a support frame 1, and the support frame 1 includes a lifting plate 101, a lifting plate 102 and a connecting plate 103. The lifting plate 101 and the lifting plate 102 are fixedly connected by the connecting plate 103, and the connecting plate 103 is located in the middle of the lifting plate 101.

[0024] A demoulding assembly is installed on the support frame 1; the demoulding assembly includes a mounting plate 3 and a mold core 4, the two groups of mounting plates 3 are symmetrical about the connecting plate 103, one end of the two groups of mounting plates 3 are rotatably connected to the lifting plate 101 / lifting plate 2 102 through a rotating shaft 10, the other ends of the two groups of mounting plates 3 are rotatably connected to the lifting plate 2 102 / lifting plate 1 101 through a connecting shaft 11, and multiple groups of mold cores 4 are installed on both sides of the two groups of mounting plates 3.

[0025] Preferably, the distances between any two adjacent groups of mold cores 4 along the length direction of the mounting plate 3 are equal.

[0026] A cover plate 2 is installed on the outer side of lifting plate 101 / lifting plate 2, and a receiving groove 6 is opened in the cover plate 2. The receiving groove 6 includes a rotating part receiving groove 601 and two groups of linkage part receiving grooves 602. The two groups of linkage part receiving grooves 602 are symmetrical about the axis center of the rotating part receiving groove 601, and the rotating part receiving groove 601 connects the two groups of linkage part receiving grooves 602. A large gear 5 is installed in the rotating part receiving groove 601, and a rack 9 and a rotating wheel 8 are installed in the linkage part receiving groove 602. The two groups of racks 9 are meshed and connected with the large gear 5, and the end of the rack 9 away from the large gear 5 is meshed and connected with the rotating wheel 8. The diameter of the rotating wheel 8 is smaller than the diameter of the large gear 5. The two groups of rotating wheels 8 are respectively fixedly connected to a group of connecting shafts 11, and a rotating rod 12 is installed at the end of the large gear 5 away from the support frame 1. The rotating axis of the rotating rod 12 is fixedly connected and coaxial with the large gear 5.

[0027] Preferably, the two sets of rotating wheels 8 are symmetrical about the large gear 5 .

[0028] Preferably, the end of the linkage member receiving groove 602 away from the large gear 5 is connected to the outside world, and a pressure plate 7 is installed at the opening of the linkage member receiving groove 602. The two groups of pressure plates 7 make the receiving groove 6 closed to prevent dust from entering the receiving groove 6 and damaging the gear and rack. The rack 9 is slidably connected to the pressure plate 7 and the length of the rack 9 is less than the length of the pressure plate 7.

[0029] During demoulding, the staff stand on both sides of the lifting plate 101 to demould the multiple groups of mold cores 4 on the side of the two groups of mounting plates 3 away from the connecting plate 103. After the demoulding is completed, the staff rotates the rotating rod 12, and the rotating rod 12 drives the large gear 5 to rotate. The large gear 5 drives the racks 9 on both sides to move toward each other. The racks 9 on both sides respectively drive the two groups of rotating wheels 8 to rotate. The rotating wheels 8 drive the mounting plate 3 to rotate 180 degrees through the connecting shaft 11, so that the multiple groups of mold cores 4 originally close to the side of the connecting plate 103 turn to the staff, which is convenient for the staff. After all the demoulding is completed, the rotating rod 12 can be rotated in the opposite direction to restore it to its original state, which is convenient for the next mold closing.

[0030] When the components in the receiving groove 6, such as the rack 9, the large gear 5 or the rotating wheel 8, are damaged and need to be replaced, the pressing plate 7 on the corresponding side can be removed to conveniently replace the components.
