[0002] Tire vulcanization refers to the vulcanization of the outer tire, which is carried out by means of model pressing. The characteristic is that the outer diameter of the formed tire blank of the outer tire is smaller than the inner diameter of the model. During vulcanization, a water bag or a capsule is installed inside the tire blank, and high-pressure hot water is injected into the water bag. The expansion pressure of the water bag or the capsule is used to make the outer tire blank fill the model.

[0003] However, when unloading the tire, the central mechanism in the lower mold will extend to move the tire to the outside. If the tire is directly clamped for unloading, it is very easy for the tire to fall due to unstable clamping, and the tire needs to be clamped again, increasing the unloading time. Therefore, how to solve this problem needs to be considered. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Referring to Figures 1-4 , a tire vulcanization automatic unloading device, including a bottom plate 1, two slide rails 2 are installed at the upper end of the bottom plate 1, sliders 3 are slidably connected in both of the two slide rails 2, and a lower die assembly 4 is jointly installed at the upper ends of the two sliders 3. An upper die assembly 5 is installed at the upper end of the bottom plate 1. Among them, both the lower die assembly 4 and the upper die assembly 5 are prior arts and will not be elaborated here. After the tire vulcanization is completed, the slide rails 2 can be started to move the lower die assembly 4 to the unloading position, and then the tire is moved to the outside by the expansion of the central mechanism in the lower die assembly 4. A first electric push rod 6 is installed at the upper end of the bottom plate 1. The telescopic end of the first electric push rod 6 is fixedly connected to a lifting plate 7. Two first rotating shafts 8 are rotatably connected to the upper end of the lifting plate 7. Protective layers are provided at the upper ends of the two first rotating shafts 8. Both of the two protective layers are made of rubber material;

[0022] Among them, a first motor 10 is installed at the lower end of the lifting plate 7. The output shaft end of the first motor 10 penetrates through the lifting plate 7 and is fixedly connected to the lower end of one of the first rotating shafts 8. Gears 11 are installed on both of the two first rotating shafts 8. The two gears 11 are meshed. Under the meshing action of the two gears 11, the two support plates 9 rotate to the lower part of the tire. Then, the first electric push rod 6 is started to make the upper ends of the two support plates 9 fit with the lower end of the tire to support the tire, ensuring the stability of the tire, facilitating the central mechanism in the lower die assembly 4 to return to its original position, and facilitating the subsequent clamping of the tire. An installation groove is opened at the upper end of the bottom plate 1. A second motor 12 is installed in the installation groove. The output shaft end of the second motor 12 is fixedly connected to a second rotating shaft 13. A rotating plate 14 is fixedly connected to the upper end of the second rotating shaft 13. A hydraulic cylinder 15 is installed at the lower end of the rotating plate 14. The telescopic end of the hydraulic cylinder 15 is fixedly connected to a T-shaped plate 16;

[0023] Wherein, second electric push rods 17 are installed on the inner walls on both sides of the T-shaped plate 16. Fixed plates 18 are fixedly connected to the telescopic ends of the two second electric push rods 17. Two fixing rods 19 are fixedly connected to the lower ends of the two fixed plates 18. The lower ends of every two cooperating fixing rods 19 are fixedly connected together with a clamping plate 20. The two clamping plates 20 are both arc-shaped. Rubber layers are arranged on the upper end surfaces of the two clamping plates 20. Move the two clamping plates 20 to the lower part of the tire through the inner diameter of the tire, and then move the two clamping plates 20 away from each other until the two clamping plates 20 are attached to the lower end surface of the tire, thus completing the clamping of the tire. Through the cooperation of the second motor 12 and the second rotating shaft 13, the tire is rotated out above the bottom plate 1. Then, move the two clamping plates 20 relatively back to their original positions, and the clamping of the tire can be released for discharging. The distance between the two clamping plates 20 can be adjusted so as to adapt to tires with different inner diameters.

[0024] In the present utility model, after the vulcanization of the tire is completed, start the two slide rails 2 to make the two sliders 3 move. The two sliders 3 drive the lower die assembly 4 to move to the discharging position. At this time, the central mechanism in the lower die assembly 4 extends and drives the tire to move upward. After moving upward for a certain distance, start the first motor 10. After the first motor 10 is started, it drives the corresponding first rotating shaft 8 to rotate. Under the meshing action of the two gears 11, the other first rotating shaft 8 also rotates accordingly, and then the two support plates 9 rotate. Rotate the two support plates 9 to the lower part of the tire, start the first electric push rod 6 to make the lifting plate 7 move, and then make the two support plates 9 attached to the lower end of the tire to support it. At this time, the central mechanism in the lower die assembly 4 returns to its original position, and the tire is supported by the two support plates 9 to ensure the stability of the tire and facilitate subsequent discharging.

[0025] Then, the hydraulic cylinder 15 can be started to make the T-shaped plate 16 move downward, and then the multiple fixing rods 19 drive the corresponding clamping plates 20 to move downward until the multiple clamping plates 20 move downward to the lower end of the tire through the inner diameter of the tire. Then start the two second electric push rods 17 to make the two fixed plates 18 move away from each other, and then the multiple fixing rods 19 drive the corresponding clamping plates 20 to move away from each other until the upper ends of the two clamping plates 20 are attached to the lower end of the tire to clamp the tire. At this time, the second motor 12 can be started to make the second rotating shaft 13 rotate, drive the tire to rotate out above the bottom plate 1, move the two clamping plates 20 relatively to make them return to their original positions, release the clamping of the tire, and then the tire can be automatically discharged.

[0026] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
