[0002] In the existing solid tire production technology, after the forming process, various products need to be transferred to a vulcanizer for vulcanization. During the vulcanization process, the tire blank needs to be grasped inside the mold of the vulcanizer, and after being treated under high temperature and high pressure, the tire needs to be taken out of the mold.

[0003] However, in the operation of a multi-layer solid tire vulcanizer, the staff must pull out the molds of each layer along the height of the multi-layer equipment for tire loading, and then put these molds back into the heating plate for vulcanization. After vulcanization, the staff must pull out and open the molds for tire unloading. This series of operations not only takes time and effort, but also poses relatively high requirements on the physical fitness of the operators.

[0025] In order to enable those skilled in the art of this technology to better understand the solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0026] Please refer to Figures 1 to 5, according to the embodiments of the present utility model, a push-pull die device is provided. The push-pull die device includes: a bearing structure 1, a push-pull structure 2, and a moving structure 3. The bearing structure 1 is movably arranged along the height direction of the vulcanizing machine; the push-pull structure 2 is located above the bearing structure 1 and is used to move the vulcanizing die out of or back into the vulcanizing machine; the moving structure 3 is arranged on the bearing structure 1, and at least part of the moving structure 3 is movably arranged relative to the bearing structure 1 so that at least part of the moving structure 3 is docked with or away from the workbench of the vulcanizing machine; the push-pull structure 2 is arranged on the moving structure 3, and at least part of the push-pull structure 2 is movably arranged relative to the moving structure 3; wherein, when at least part of the moving structure 3 is docked with the vulcanizing machine, at least part of the push-pull structure 2 moves relative to the moving structure 3 to move the vulcanizing die out of the vulcanizing machine onto the moving structure 3, or to move the vulcanizing die from the moving structure 3 back onto the vulcanizing machine.

[0027] It can be seen that in the push-pull die device provided by the present utility model, the bearing structure 1 is movably arranged along the height direction of the vulcanizer, the moving structure 3 is arranged on the bearing structure 1, and the push-pull structure 2 is arranged on the moving structure 3. Furthermore, the bearing structure 1 drives the push-pull structure 2 and the moving structure 3 to move along the height direction of the vulcanizer, so as to drive the push-pull structure 2 and the moving structure 3 to the vicinity of the working table of the vulcanizer. At the same time, the push-pull structure 2 is arranged on the moving structure 3, and at least part of the push-pull structure 2 is movably arranged relative to the moving structure 3; and the moving structure 3 is arranged on the bearing structure 1, and at least part of the moving structure 3 is movably arranged relative to the bearing structure 1. Furthermore, when the bearing structure 1 drives the moving structure 3 to move to the vicinity of the working table of the vulcanizer, at least part of the moving structure 3 can be docked with the working table of the vulcanizer, and at least part of the push-pull structure 2 can move relative to the moving structure 3, so that the vulcanization die can be moved out of the vulcanizer onto the moving structure 3, or the vulcanization die can be moved back from the moving structure 3 to the working table of the vulcanizer. And when the push-pull structure 2 moves the vulcanization die from the vulcanizer to the moving structure 3 along at least part of the moving direction of the moving structure 3, the moving structure 3 drives the vulcanization die and the push-pull structure 2 to move in a direction away from the vulcanizer, so that the vulcanization die is far away from the vulcanizer, which is convenient for operators or manipulators to mount or dismount tires. And the movability of at least part of the moving structure 3 ensures that the vulcanization die can be loaded and unloaded at a safe position, avoiding collisions between operators or manipulators and other components, thereby reducing the safety hazards of operators or reducing the wear and damage of the device, and prolonging the service life of the device. Thus, through the mutual cooperation of the bearing structure 1, the moving structure 3 and the push-pull structure 2, the rapid removal and return of the vulcanization die are realized, the time of manual operation is reduced, and the production efficiency is improved. And the automatic removal and return functions reduce the demand for labor and lower the labor cost. And through the movement of the moving structure 3, the vulcanization die can be easily moved out of the vulcanizer, which is convenient for maintenance and repair work. The push-pull die device has a simple structure and is easy to operate, and can effectively solve the technical problem in the prior art that it is necessary to manually pull out each layer of die on the multi-layer solid tire vulcanizer for tire mounting or dismounting.

[0028] Furthermore, at least part of the moving structure 3 moves in a direction towards or away from the vulcanizer.

[0029] Optionally, when it is necessary to load green embryos for vulcanization work, the working process of the push-pull die device is as follows:

[0030] First, the bearing structure 1 moves along the height direction of the vulcanizer, driving the push-pull structure 2 and the moving structure 3 to the vicinity of the working table of the vulcanizer. Then at least part of the moving structure 3 moves towards the working table of the vulcanizer until at least part of the moving structure 3 is docked with the working table of the vulcanizer.

[0031] After the docking is completed, at least a part of the pushing and pulling structure 2 moves along the moving direction of at least a part of the moving structure 3 and moves to a side close to the working table of the vulcanizer. Then, at least a part of the pushing and pulling structure 2 is connected to the lower die of the vulcanizing die. As at least a part of the pushing and pulling structure 2 moves along the moving direction of at least a part of the moving structure 3 away from the vulcanizer, the vulcanizing die is moved onto the moving structure 3.

[0032] When the vulcanizing die is moved onto the moving structure 3, first, the upper die and the lower die of the vulcanizing die are separated. Then, at least a part of the moving structure 3 drives the lower die of the vulcanizing die and the pushing and pulling structure 2 to move away from the vulcanizer. When reaching the designated position, the green tire is placed into the cavity of the lower die of the vulcanizing die by a manipulator or an operator. After placing, at least a part of the moving structure 3 moves to continue docking with the working table of the vulcanizer. After docking, the upper die of the vulcanizing die and the lower die of the vulcanizing die are closed. After the closing is completed, at least a part of the pushing and pulling structure 2 pushes the vulcanizing die onto the working table of the vulcanizer, and then the pushing and pulling structure 2 is separated from the lower die of the vulcanizing die. Finally, at least a part of the moving structure 3 drives the pushing and pulling structure 2 away from the vulcanizer. Or, when the vulcanizing die is moved onto the moving structure 3, at least a part of the moving structure 3 can directly drive the vulcanizing die and the pushing and pulling structure 2 to move away from the vulcanizer. After reaching the designated position, the die opening process, the tire mounting process, and the die closing process are carried out. After the die closing process is completed, at least a part of the moving structure 3 moves to continue docking with the working table of the vulcanizer. Then, at least a part of the pushing and pulling structure 2 pushes the vulcanizing die onto the working table of the vulcanizer. Then, the pushing and pulling structure 2 is separated from the lower die of the vulcanizing die. Finally, at least a part of the moving structure 3 drives the pushing and pulling structure 2 away from the vulcanizer.

[0033] Specifically, such as Figure 1 、 Figure 2 and Figure 5As shown in the figure, the push-pull structure 2 includes: a locking member 21, which is movably arranged on the moving structure 3. The locking member 21 has a locking portion 211 for locking and mating with a locking mating portion on the vulcanizing mold that is adapted to the locking portion 211. Among them, when the push-pull structure 2 needs to move the vulcanizing mold from the vulcanizer to the moving structure 3, the locking member 21 moves towards the direction of the vulcanizing mold, so that the locking portion 211 is locked and mated with the locking mating portion on the vulcanizing mold. When the push-pull structure 2 moves the vulcanizing mold back from the moving structure 3 to the vulcanizer, the locking member 21 moves towards the direction away from the vulcanizing mold, so that the locking portion 211 is separated from the locking mating portion on the vulcanizing mold. With such a structural arrangement, by providing the locking member 21 and enabling the locking portion 211 to be locked and mated with the locking mating portion on the vulcanizing mold, during the process of the push-pull structure 2 moving the vulcanizing mold from the vulcanizer to the moving structure 3 or the push-pull structure 2 moving the vulcanizing mold back from the moving structure 3 to the vulcanizer, the push-pull structure 2 is firmly connected to the vulcanizing mold, reducing shaking or loosening during the movement, ensuring the stability and safety of the entire vulcanizing mold during the movement. And it effectively prevents the mold from falling off or slipping during the movement, reducing the safety hazards for the operators.

[0034] Furthermore, a locking mating portion adapted to the locking portion 211 is provided on the lower mold of the vulcanizing mold. When the push-pull structure 2 drives the vulcanizing mold to move, the locking portion 211 is locked and mated with the locking mating portion on the lower mold of the vulcanizing mold.

[0035] Optionally, when the push-pull structure 2 needs to move the vulcanizing mold from the vulcanizer to the moving structure 3, the locking member 21 moves towards the direction of the vulcanizing mold, so that the locking portion 211 is locked and mated with the locking mating portion on the lower mold of the vulcanizing mold. Then, at least a part of the push-pull structure 2 moves the vulcanizing mold to the moving structure 3 to perform the tire mounting or demounting process. During the tire mounting or demounting process, the locking portion 211 and the locking mating portion on the lower mold of the vulcanizing mold can always be in a locked and mated state. When the push-pull structure 2 moves the vulcanizing mold back to the working table of the vulcanizer, the locking member 21 moves towards the direction away from the vulcanizing mold, so that the locking portion 211 is separated from the locking mating portion on the lower mold of the vulcanizing mold.

[0036] Furthermore, as Figures 1 to 3 and Figure 5As shown, the locking member 21 further has a connecting portion 212; the push-pull structure 2 further includes: a support platform 22, which is movably arranged on the moving structure 3 along at least part of the moving direction of the moving structure 3; one end of the connecting portion 212 is rotatably arranged on the support platform 22 relative to the support platform 22, the other end of the connecting portion 212 faces the vulcanizing mold, and the other end of the connecting portion 212 is connected to the locking portion 211; when the connecting portion 212 rotates relative to the support platform 22, the connecting portion 212 drives the locking portion 211 to move away from or close to the vulcanizing mold. With such a structural arrangement, by providing the support platform 22, the locking member 21 can be driven to move in the direction towards or away from the vulcanizing machine along at least part of the moving direction of the moving structure 3. Furthermore, after the locking portion 211 is in locking cooperation with the locking cooperation portion on the vulcanizing mold, the vulcanizing mold can be moved out of the vulcanizing machine onto the moving structure 3 or moved back from the moving structure 3 to the vulcanizing machine through the movement of the support platform 22, thereby enhancing the flexibility and convenience of the operation. In addition, the connecting portion 212 rotates relative to the support platform 22, and the connecting portion 212 can drive the locking portion 211 to move away from or close to the locking cooperation portion on the vulcanizing mold, so as to ensure that the locking portion 211 is properly locked or separated from the locking cooperation portion on the vulcanizing mold, reducing potential safety hazards caused by improper locking. At the same time, the rotation mechanism of the connecting portion 212 can ensure stable contact between the locking portion 211 and the vulcanizing mold, improving the stability of the entire system. And through the linkage effect of the support platform 22 and the connecting portion 212, the operation process of the locking member 21 can be simplified, reducing the burden on the operator. And the removal and return of the vulcanizing mold can be quickly realized, improving production efficiency.

[0037] Optionally, the end of the connecting portion 212 away from the locking portion 211 is located on the side of the support platform 22 close to the vulcanizing machine, and the end of the connecting portion 212 connected to the locking portion 211 is located outside the side of the support platform 22 close to the vulcanizing machine, so that the locking portion 211 extends out of the support platform 22.

[0038] Further, as Figures 1 to 3 and Figure 4, the push-pull structure 2 further includes: a connecting shaft 23 and a telescopic assembly 24. The connecting shaft 23 is arranged on the support platform 22, and the axis direction of the connecting shaft 23 is perpendicular to the moving direction of the support platform 22; one end of the connecting portion 212 away from the locking portion 211 is sleeved on the connecting shaft 23, and the connecting portion 212 rotates relative to the support platform 22 around the axis of the connecting shaft 23; the telescopic assembly 24 is arranged on the support platform 22, and at least part of the telescopic assembly 24 is located at the bottom of the support platform 22, and the output end of the telescopic rod of the telescopic assembly 24 is connected to the connecting portion 212; along the extending direction of the telescopic rod, the height of the output end of the telescopic rod gradually increases; so as to drive the connecting portion 212 to rotate relative to the support platform 22 around the axis of the connecting shaft 23 through the telescopic movement of the telescopic rod. With such a structural arrangement, the rotation of the connecting portion 212 is driven by the telescopic movement of the telescopic assembly 24, so that the flexible connection and separation between the locking portion 211 and the locking mating portion on the vulcanization mold can be realized, and the operation flexibility is improved. The telescopic assembly 24 can quickly lock or unlock the locking portion 211 and the vulcanization mold, improving the production efficiency.

[0039] The first embodiment of the connection between the connecting portion 212 and the connecting shaft 23 provided in this embodiment is: the connecting shaft 23 is rotatably arranged on the support platform 22; one end of the connecting portion 212 away from the locking portion 211 is sleeved on the connecting shaft 23, and one end of the connecting portion 212 away from the locking portion 211 is fixedly connected to the connecting shaft 23 relatively. When the connecting portion 212 rotates relative to the support platform 22 around the axis of the connecting shaft 23, the connecting portion 212 drives the connecting shaft 23 to rotate around the axis of the connecting shaft 23. Thus, the connecting portion 212 drives the locking portion 211 to move towards the vulcanization mold or drives the locking portion 211 to move away from the vulcanization mold.

[0040] The second embodiment of the connection between the connecting portion 212 and the connecting shaft 23 provided in this embodiment is: the connecting shaft 23 and the support platform 22 are fixedly connected relative to each other, and one end of the connecting portion 212 away from the locking portion 211 is rotatably sleeved on the connecting shaft 23, so that the connecting portion 212 rotates relative to the support platform 22 around the axis of the connecting shaft 23. Thus, the connecting portion 212 drives the locking portion 211 to move towards the vulcanization mold or drives the locking portion 211 to move away from the vulcanization mold.

[0041] Further, the telescopic assembly 24 is inclined relative to the support platform 22. The telescopic direction of the telescopic rod of the telescopic assembly forms a preset angle with the vertical direction, and this preset angle is less than 90° and greater than 0°. It can also be understood that the telescopic direction of the telescopic rod of the telescopic assembly 24 is inclined at a certain angle with the moving direction of the support platform 22, and the angle range of the angle formed between the telescopic direction of the telescopic rod of the telescopic assembly 24 and the moving direction of the support platform 22 is less than 90° and greater than 0°.

[0042] Optionally, when the telescopic component 24 is inclined relative to the support platform 22 and the locking portion 211 of the locking member 21 needs to be locked and cooperated with the locking cooperation portion on the vulcanization mold, the telescopic rod of the telescopic component 24 contracts. Since the output end of the telescopic rod of the telescopic component 24 is connected to the connecting portion 212, a downward force is applied to the connecting portion 212, so that the end of the connecting portion 212 away from the locking portion 211 rotates around the axis of the connecting shaft 23, causing the connecting portion 212 to drive the locking portion 211 to swing downward (i.e., swing towards the direction of the vulcanization mold). Finally, the locking portion 211 is locked and cooperated with the locking cooperation portion on the vulcanization mold. When the telescopic component 24 is inclined relative to the support platform 22 and the locking portion 211 of the locking member 21 needs to be separated from the locking cooperation portion on the vulcanization mold, the telescopic rod of the telescopic component 24 extends. Since the output end of the telescopic rod of the telescopic component 24 is connected to the connecting portion 212, an upward force is applied to the connecting portion 212, so that the end of the connecting portion 212 away from the locking portion 211 rotates around the axis of the connecting shaft 23, causing the connecting portion 212 to drive the locking portion 211 to swing upward (i.e., swing towards the direction away from the vulcanization mold). Finally, the locking portion 211 is separated from the locking cooperation portion on the vulcanization mold.

[0043] Preferably, the telescopic component 24 is a first cylinder.

[0044] Further, the pushing and pulling structure 2 further includes: a first mounting bracket 221 and a second mounting bracket 222 arranged at intervals along the axis of the connecting shaft 23. The first mounting bracket 221 and the second mounting bracket 222 are mounted on the support platform 22. A first mounting space is formed among the support platform 22, the first mounting bracket 221 and the second mounting bracket 222.

[0067] The present utility model further provides a tire loading and unloading device, which is used to place a green tire onto a vulcanizing mold or remove a vulcanized tire from the vulcanizing mold; as Figure 6 shown, the tire loading and unloading device includes: a push-pull mold device, which is the push-pull mold device of the above embodiment.

[0068] Specifically, as Figure 6 shown, the tire loading and unloading device further includes: a mold opening device 600 and a tire loading and unloading device 700. The mold opening device 600 is located on the push-pull mold device. The mold opening device 600 is movably arranged relative to the push-pull mold device along the height direction of the vulcanizer. The mold opening device 600 is used to separate or close the upper mold and the lower mold of the vulcanizing mold. The tire loading and unloading device 700 is movably arranged to load a green tire into the cavity of the lower mold of the vulcanizing mold or remove a vulcanized tire from the lower mold of the vulcanizing mold and move it to a designated position for tire unloading.

[0069] Optionally, the working process of the tire loading and unloading device (taking the tire unloading of the tire loading and unloading device as an example) is as follows:

[0070] First, the bearing structure 1 in the push-pull mold device first moves the moving structure 3 and the push-pull structure 2 to one side of the working table of the vulcanizer. Then, the moving table 31 of the moving structure 3 moves towards the vulcanizer, and then docks with the working table of the vulcanizer. After docking, the support table 22 of the push-pull structure 2 drives the locking member 21 of the push-pull structure 2 towards the vulcanizing mold. At this time, the telescopic rod of the telescopic assembly 24 is in the extended state, and the locking portion 211 of the locking member 21 is above the lower mold of the vulcanizing mold. When the support table 22 of the push-pull structure 2 reaches the designated position, the telescopic rod of the telescopic assembly 24 contracts to drive the locking portion 211 of the locking member 21 towards the lower mold of the vulcanizing mold, so that the locking portion 211 of the locking member 21 is in locking cooperation with the lower mold of the vulcanizing mold. When the push-pull structure 2 is connected to the lower mold of the vulcanizing mold, the vulcanizing mold is moved out into the guide groove 310 of the moving table 31. When the vulcanizing mold is located in the guide groove 310 of the moving table 31, both sides of the lower mold of the vulcanizing mold are located in the corresponding limiting grooves 311, thereby limiting the lower mold of the vulcanizing mold.

[0071] Secondly, the mold opening device 600 is locked and connected to the upper mold of the vulcanizing mold, and drives the upper mold of the vulcanizing mold to move away from the push-pull mold device along the height direction of the vulcanizer, thereby realizing the mold opening process. After mold opening, the moving table 31 of the moving structure 3 drives the lower mold of the vulcanizing mold and the push-pull mold to move away from the vulcanizer, so that the lower mold of the vulcanizing mold avoids the mold opening device 600.

[0072] Finally, after the mobile station 31 of the mobile structure 3 moves to the preset position, the tire loading and unloading device 700 moves to the lower die of the vulcanization mold to grasp the tire, and then drives the tire to move to the tire unloading position for tire unloading.

[0073] The utility model provides a push-pull die device, which includes a bearing structure 1, a push-pull structure 2 and a mobile structure 3. The bearing structure 1 is movably arranged along the height direction of the vulcanizer; the push-pull structure 2 is located above the bearing structure 1 and is used to move the vulcanization mold out of or back into the vulcanizer; the mobile structure 3 is arranged on the bearing structure 1, and at least part of the mobile structure 3 is movably arranged relative to the bearing structure 1 so that at least part of the mobile structure 3 is docked with the workbench of the vulcanizer or away from the workbench of the vulcanizer; the push-pull structure 2 is arranged on the mobile structure 3, and at least part of the push-pull structure 2 is movably arranged relative to the mobile structure 3; wherein, when at least part of the mobile structure 3 is docked with the vulcanizer, at least part of the push-pull structure 2 moves relative to the mobile structure 3 to move the vulcanization mold from the vulcanizer to the mobile structure 3, or to move the vulcanization mold from the mobile structure 3 back to the vulcanizer.

[0074] It can be seen that for the push-pull die device provided by the present utility model, the bearing structure 1 is movably arranged along the height direction of the vulcanizer, the moving structure 3 is arranged on the bearing structure 1, and the push-pull structure 2 is arranged on the moving structure 3. Thus, the bearing structure 1 drives the push-pull structure 2 and the moving structure 3 to move along the height direction of the vulcanizer, so as to drive the push-pull structure 2 and the moving structure 3 near the workbench of the vulcanizer. At the same time, the push-pull structure 2 is arranged on the moving structure 3, and at least part of the push-pull structure 2 is movably arranged relative to the moving structure 3; and, the moving structure 3 is arranged on the bearing structure 1, and at least part of the moving structure 3 is movably arranged relative to the bearing structure 1. Thus, when the bearing structure 1 drives the moving structure 3 to move near the workbench of the vulcanizer, at least part of the moving structure 3 can be docked with the workbench of the vulcanizer, and at least part of the push-pull structure 2 can move relative to the moving structure 3, so that the vulcanizing die can be moved out of the vulcanizer onto the moving structure 3, or the vulcanizing die can be moved back from the moving structure 3 to the workbench of the vulcanizer. And when the push-pull structure 2 moves the vulcanizing die from the vulcanizer onto the moving structure 3 along at least part of the moving direction of the moving structure 3, the moving structure 3 drives the vulcanizing die and the push-pull structure 2 to move away from the vulcanizer, so that the vulcanizing die is far away from the vulcanizer, which is convenient for operators or manipulators to mount or dismount tires. And the movability of at least part of the moving structure 3 ensures that the vulcanizing die can be loaded and unloaded at a safe position, avoiding collisions between operators or manipulators and other components, thus reducing the safety hazards of operators or reducing the wear and damage of the device, and prolonging the service life of the device. It can be seen that through the mutual cooperation of the bearing structure 1, the moving structure 3 and the push-pull structure 2, the rapid removal and return of the vulcanizing die are realized, the time of manual operation is reduced, and the production efficiency is improved. And the automatic removal and return functions reduce the demand for labor and lower the labor cost. And through the movement of the moving structure 3, the vulcanizing die can be easily moved out of the vulcanizer, which is convenient for maintenance and repair work. The push-pull die device has a simple structure and is easy to operate, and can effectively solve the technical problem in the prior art that it is necessary to manually pull out each layer of die on the multi-layer solid tire vulcanizer for tire mounting or dismounting.
