[0054] With reference to Figure 5 and Figure 6 The cam 83 is sleeved on the peripheral wall of the rotating rod 81 and can rotate with the rotating rod 81; the brake plate 84 is slidingly connected in the brake cavity 25, the connecting rod 31 passes through the brake plate 84, and the brake plate 84 can slide along the length direction of the connecting rod 31; one end of the reset spring 85 is adhesively connected to the surface of the brake plate 84, and the other end is adhesively connected to the top wall of the brake cavity 25, which can limit the brake plate 84 and prevent the brake plate 84 from falling off, and can effectively reset the brake plate 84 after moving; in the embodiment, when the placing table rises, the cam 83 rotates, and the long end of the cam 83 pushes the brake plate 84 towards the protective cover 32.

[0055] With reference to Figure 5 and Figure 6 The brake piece 86 is arc-shaped, is arranged between the corresponding protective cover 32 and the hub 33, and the side wall, away from the hub 33, of the brake piece 86 is connected with two abutting rods 861 through welding; one end of the brake spring 87 is adhesively connected to the side wall, away from the hub 33, of the brake piece 86, and the other end is adhesively connected to the inner wall of the protective cover 32; the outer wall of the hub 33 is integrally formed with a plurality of first anti-skid convex patterns 331, which are uniformly arranged along the circumferential direction of the hub 33; the side wall, facing the hub 33, of the brake piece 86 is integrally formed with a plurality of second anti-skid convex patterns 862; when the brake piece 86 is pushed towards the hub 33, the second anti-skid convex patterns 862 are inserted between two first anti-skid convex patterns 331, so that the friction between the brake piece 86 and the hub 33 is generated, thereby effectively braking the hub 33, so that the roller 3 cannot rotate when the mold 1 is taken or placed by the operator, thereby reducing the probability of sliding of the carrying device and improving the stability of the carrying device.

[0056] The implementation principle of the mold carrying device is as follows: the lifting cylinder 6 is started, and the lifting cylinder 6 drives the placing table to rise, in the process, the driving rack 71 is engaged with the driving gear 72, so that the driving gear 72 drives the driven gear 73 to rotate, the driven gear 73 drives the rotating gear 75 to rotate through the connecting rod 74, so that the rotating gear 75 drives the driven rack 76 to move, thereby driving the turnover gear 77 to rotate and the corresponding cover plate 231 to open, and the worker can place the mold 1 in the embedded groove 41;

[0057] When the cover plate 231 is opened, the linkage gear one 51 rotates with the cover plate 231, drives the linkage gear two 52 and the linkage rack 54 to move, and the abutting column 53 is retracted into the gap slot 22, and the abutting block 221 also moves away from the mold 1 under the action of the tension spring 57;

[0058] Meanwhile, the movement of the driving rack 71 drives the rotation of the brake gear 82, so that the long end of the cam 83 can push the brake plate 84 towards the abutting rod 861, the brake plate 84 pushes the abutting rod 861 and the brake piece 86, so that the second anti-skid convex pattern 862 of the brake piece 86 abuts against the first anti-skid convex pattern 331 of the wheel hub 33, thereby increasing the friction between the brake piece 86 and the wheel hub 33, preventing the rotation of the roller 3, reducing the probability of the carrying table 2 sliding when the mold 1 is placed in the embedded groove 41, and improving the stability and safety;

[0059] When the placing table descends, the cover plate 231 will gradually close, accompanied by the gradual abutting of the abutting block 221 to the mold 1 and the release of the roller 3 brake, and when the lifting cylinder 6 stops running, the carrying table 2 can be pushed to transport the mold 1.

[0060] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made on the basis of the structure, shape, principle of the present application should be covered within the protection scope of the present application.
