[0002] In the existing solid tire production technology, the formed green tire needs to be transferred to a vulcanizer for vulcanization. After being treated under high temperature and high pressure, the vulcanized tire needs to be taken out of the mold.

[0003] Currently, the tire unloading process is usually completed by matching a demoulding device with a manipulator. The specific steps are as follows: after the upper mold is opened, first use the demoulding device to eject the lower steel ring and the tire from the lower mold, and then use the manipulator to grab the tire and place it at a designated position. However, during the tire vulcanization process, high temperature and high pressure may cause a certain adhesion between the tire material and the lower steel ring.

[0015] Beneficial effects:

[0016] Applying the technical solution of the present utility model, the demolding device provided by the present utility model can eject the tire from the lower mold cavity by simply arranging a mounting seat, an ejection structure and a locking structure, and the ejection structure is vertically liftably arranged on the mounting seat. Thus, through the contact between the ejection structure and the lower steel ring, the tire can be ejected from the lower mold cavity. It can be seen that this design can quickly realize the demolding of the tire and improve the production efficiency. Moreover, through the contact between the ejection structure and the lower steel ring, it can ensure that the tire is smoothly ejected from the lower mold cavity, avoiding tire damage or deformation caused by unstable ejection.

[0028] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0029] Please refer to Figures 1 to 7According to an embodiment of the utility model, a demoulding device is provided, which is used to eject a vulcanized tire from a lower mold cavity of a lower mold. The demoulding device comprises: a mounting seat 1, an ejection structure 2 and a locking structure 3. The mounting seat 1 is located below the lower mold; the ejection structure 2 is arranged on the mounting seat 1 in a manner that it can be lifted and lowered in a vertical direction; the ejection structure 2 is used to abut against a lower steel ring of the lower mold, and the ejection structure 2 ejects the tire from the lower mold cavity through the lower steel ring; the locking structure 3 is arranged on the ejection structure 2, and at least a portion of the locking structure 3 is movably arranged relative to the ejection structure 2; the locking structure 3 has a locking position and an avoidance position. When the locking structure 3 is in the locking position, at least a portion of the locking structure 3 moves toward the direction of the lower steel ring, so that the locking structure 3 is locked and connected with the lower steel ring, so that the lower steel ring is separated from the tire when the tire is removed; when the locking structure 3 is in the avoidance position, at least a portion of the locking structure 3 moves in a direction away from the lower steel ring, so that the locking structure 3 and the lower steel ring are separated from each other.

[0030] It can be seen that the demoulding device provided by the utility model is provided by simply setting a mounting seat 1, an ejection structure 2 and a locking structure 3, and the ejection structure 2 is arranged on the mounting seat 1 in a manner that can be lifted and lowered in the vertical direction, and then the ejection structure 2 ejects the tire from the lower mold cavity by contacting the lower steel ring. It can be seen that this design can quickly realize the demoulding of the tire and improve production efficiency. In addition, through the contact between the ejection structure 2 and the lower steel ring, it can ensure that the tire is smoothly ejected from the lower mold cavity, avoiding damage or deformation of the tire caused by unstable ejection. At the same time, the design of the ejection structure 2 can also reduce the friction between the tire and the lower mold, and reduce wear and damage caused by excessive force. Through the precise control of the ejection structure 2, manual intervention in the operation process can be reduced, the operation risk is reduced, and safety is improved. In addition, by ensuring that the tire is smoothly ejected from the lower mold cavity, the quality of the tire can be improved, and product defects caused by improper demoulding can be avoided.

[0031] In addition, a locking structure 3 is arranged on the ejection structure 2. Then, the ejection structure 2 drives the locking structure 3 to move towards the lower die, so that when the ejection structure 2 abuts against the lower steel ring of the lower die, at least part of the locking structure 3 passes through the lower die and is located above the lower steel ring. Then, at least part of the locking structure 3 moves towards the lower steel ring, so that the locking structure 3 is locked and connected to the lower steel ring. Thus, when the ejection structure 2 ejects the tire from the lower die cavity through the lower steel ring and the tire is taken out, the lower steel ring can be locked on the demoulding device through the locking structure 3, so that the lower steel ring is separated from the tire. When it is not necessary to lock the lower steel ring, at least part of the locking structure 3 moves in a direction away from the lower steel ring, so that the locking structure 3 is separated from the lower steel ring. It can be seen that by arranging the locking structure 3, it can effectively prevent the lower steel ring from being taken away together during the tire taking process, improving the safety of the operation. And it ensures that the lower steel ring stays stably in place during the tire taking process, improving the stability of the whole tire unloading process. Moreover, the reliable locking of the locking structure 3 can also reduce the failure rate caused by the non-separation of the lower steel ring. It reduces the operation difficulty of the operator and makes the tire unloading process more convenient. At the same time, by ensuring the effective separation of the lower steel ring and the tire, the quality of the tire can be improved, and product defects caused by improper tire unloading can be avoided. This demoulding device effectively solves the technical problem in the prior art that during the tire unloading process, the demoulding device cannot effectively lock the lower steel ring, resulting in the manipulator being prone to taking the lower steel ring away together.

[0032] Further, at least part of the locking structure 3 is located above the ejection structure.

[0033] Further, the lower die further has a housing. A central hole is provided at the bottom of the housing. A lower die cavity is provided inside the housing. The lower steel ring is located in the lower die cavity. A central hole is also provided on the lower steel ring. The central hole of the housing is concentric with the central hole of the lower steel ring. Then, when it is necessary to separate the vulcanized tire from the housing of the lower die, the ejection structure 2 moves towards the lower die, passes through the central hole of the housing of the lower die and abuts against the bottom surface of the lower steel ring. Thus, as the ejection structure 2 continues to rise, the ejection structure 2 ejects the tire through the lower steel ring, so that the tire is located above the housing of the lower die, and thus the tire is separated from the housing of the lower die.

[0034] Optionally, the working process of the demoulding device is as follows:

[0035] First, the ejection structure 2 rises relative to the mounting seat 1, so that the ejection structure 2 passes through the center hole of the shell of the lower mold and abuts against the bottom surface of the lower steel ring. After abutting, the ejection structure 2 continues to rise against the lower steel ring and the tire, and rises to a specified position. After reaching the specified position, the tire is separated from the shell of the lower mold, so that the tire and the lower steel ring are located above the shell of the lower mold. Among them, when the ejection structure 2 passes through the center hole of the shell of the lower mold and abuts against the bottom surface of the lower steel ring, at least part of the locking structure 3 passes through the shell of the lower mold and the center hole of the lower steel ring in sequence and is located above the lower steel ring. At this time, the locking structure 3 is in an avoidance position.

[0036] Secondly, when the ejection structure 2 rises to the specified position (i.e., after the ejection structure 2 ejects the tire through the lower steel ring), at least part of the locking structure 3 moves toward the lower steel ring so that the locking structure 3 is locked and connected with the lower steel ring, and then the locking structure 3 is in the locked position. Thus, the lower steel ring is locked on the demoulding device, and the tire is separated from the lower steel ring when the tire is removed.

[0037] Finally, when the lower steel ring is separated from the tire, the ejection structure 2 descends with the lower steel ring, and when the lower steel ring is placed in the shell of the lower mold, at least part of the locking structure 3 moves in the direction away from the lower steel ring, and the locking structure 3 switches from the locking position to the avoidance position, so that as the ejection structure 2 continues to descend, the locking structure 3 can be smoothly separated from the center hole of the lower steel ring and the center hole of the lower mold. Alternatively, when the operator or the manipulator holds the tire tightly to remove the tire, the ejection structure 2 descends with the lower steel ring and the locking structure 3 at the same time, so that the tire and the lower steel ring are easier to separate. Alternatively, after the tire is separated from the lower steel ring, and the ejection structure 2 has not yet descended, the locking structure 3 immediately switches from the locking position to the avoidance position.

[0038] The first embodiment of the locking structure provided in this embodiment is: Figure 1 , Figures 3 to 6As shown, the locking structure 3 includes: a mounting bracket 31 and a plurality of locking parts 32. The mounting bracket 31 is mounted on the top surface of the ejection structure 2; a plurality of avoidance spaces 310 are arranged at intervals along the circumferential direction of the mounting bracket 31 on the side wall of the mounting bracket 31, and each avoidance space 310 extends along the height direction of the mounting bracket 31; the plurality of locking parts 32 are arranged in one-to-one correspondence with the plurality of avoidance spaces 310, at least part of each locking part 32 is arranged in the corresponding avoidance space 310, and the locking end 321 of each locking part 32 is movably inserted in the corresponding avoidance space 310; each avoidance space 310 is used to avoid the locking end 321 of the corresponding locking part 32; wherein, the locking part 32 has an open state and a retracted state. When the locking structure 3 is in the locking position, each locking part 32 is in the open state, so that the locking end 321 of each locking part 32 is clamped on the edge of the central hole of the lower steel ring; when the locking structure 3 is in the avoidance position, each locking part 32 is in the retracted state, so that the locking end 321 of each locking part 32 is away from the lower steel ring. With such a structural arrangement, by providing the mounting bracket 31, a stable mounting platform can be provided for the locking part 32, ensuring the stability of the locking part 32 during use and facilitating the quick assembly and disassembly of the locking part 32. Moreover, the mounting bracket 31 provides additional support for the locking structure 3, improving the strength of the overall structure. At the same time, the avoidance space 310 provides necessary movement space for the locking end 321 of the locking part 32, ensuring that the locking end 321 can smoothly perform the opening and retracting actions. And the design of the avoidance space 310 allows the locking end 321 to flexibly switch between the open state and the retracted state, improving the flexibility of the locking structure 3. In addition, by providing the locking part 32, and the locking part 32 has an open state and a retracted state. When the locking structure 3 is in the locking position, the locking end 321 of each locking part 32 is clamped on the edge of the central hole of the lower steel ring, thereby ensuring the effective separation of the lower steel ring and the tire during the tire removal process, improving the safety of the operation and the stability of the entire tire removal process. At the same time, the efficient locking of the locking structure 3 can reduce energy consumption and save energy consumption.

[0039] Further, each locking portion 32 is initially in a retracted state, and at least a part of the locking end 321 of each locking portion 32 is located within the avoidance space 310, so as to facilitate the locking portion 32 and the mounting bracket 31 to pass through the central hole of the lower steel ring, so that at least a part of the locking portion 32 and at least a part of the mounting bracket 31 are located above the lower steel ring. When the locking structure 3 is in the locking position, the locking ends 321 of the respective locking portions 32 move in the direction towards the lower steel ring, so that the locking ends 321 of the respective locking portions 32 are clamped on the edge of the central hole of the lower steel ring, thereby locking the locking structure 3 to the lower steel ring. When the locking structure 3 is switched from the locking position to the avoidance position, each locking portion 32 is in a retracted state, and the locking ends 321 of the respective locking portions 32 move in the direction away from the lower steel ring, so that at least a part of the locking ends 321 of the respective locking portions 32 is located within the avoidance space 310.

[0040] Further, as Figure 7 shown, a limit notch 320 is provided on the locking end 321 of the locking portion 32, and the limit notch 320 is used to be clamped on the edge of the central hole of the lower steel ring, so as to lock the locking structure 3 to the lower steel ring. With such a structural arrangement, by providing the limit notch 320 on the locking end 321 of the locking portion 32, reliable locking between the locking structure 3 and the lower steel ring can be ensured, the movement of the lower steel ring can be effectively restricted, so as to ensure that the lower steel ring stays in place stably during the tire removal process, and the stability of the entire tire removal process is improved.

[0041] Wherein, when the locking structure 3 is in the locking position, the limit notch 320 is clamped on the edge of the central hole of the lower steel ring, and at least a part of the locking end 321 of the locking portion 32 abuts against the top surface of the lower steel ring, thereby locking the lower steel ring and ensuring that the lower steel ring stays in place stably during the tire removal process.

[0042] The second embodiment of the locking structure provided in this embodiment is as follows: The locking structure 3 includes: a mounting bracket 31 and a plurality of locking portions 32. The mounting bracket 31 is mounted on the top surface of the ejecting structure 2; a plurality of avoiding spaces 310 are arranged at intervals along the circumferential direction of the mounting bracket 31 on the side wall of the mounting bracket 31, and each avoiding space 310 extends along the height direction of the mounting bracket 31; the plurality of locking portions 32 are arranged in one-to-one correspondence with the plurality of avoiding spaces 310, at least part of each locking portion 32 is arranged in the corresponding avoiding space 310, and the locking end 321 of each locking portion 32 is movably inserted into the corresponding avoiding space 310; each avoiding space 310 is used for avoiding the locking end 321 of the corresponding locking portion 32; wherein, the locking portion 32 has an open state and a closed state. When the locking structure 3 is in the locking position, each locking portion 32 is in the open state, so that the locking end 321 of each locking portion 32 is located on the top end of the lower steel ring, and the locking end 321 of each locking portion 32 abuts against the lower steel ring; when the locking structure 3 is in the avoiding position, each locking portion 32 is in the closed state, so that the locking end 321 of each locking portion 32 is far away from the lower steel ring.

[0043] Among them, in the second embodiment of the locking structure provided in this embodiment, no limiting notch is provided at the locking end 321 of each locking portion 32. When the locking structure 3 is in the locking position, the locking end 321 of the locking portion 32 moves to the top surface of the lower steel ring, so that the locking end 321 of the locking portion 32 abuts against the top surface of the lower steel ring, thereby locking the lower steel ring and ensuring that the lower steel ring stays in place stably during the tire removal process.

[0044] Specifically, as Figure 6As shown, the mounting bracket 31 is provided with a communication hole 311 which extends along the height direction of the mounting bracket 31, and the communication hole 311 communicates with each avoidance space 310; the locking structure 3 further includes: a connecting portion 33 which is inserted into the communication hole 311 in a liftable manner relative to the mounting bracket 31; and the connecting ends 322 of the respective locking portions 32 are rotatably connected to the connecting portion 33; wherein, when the connecting portion 33 rises relative to the mounting bracket 31, it drives the connecting ends 322 of the respective locking portions 32 to rotate in a first preset direction, so that the respective locking portions 32 are in a retracted state; when the connecting portion 33 descends relative to the mounting bracket 31, it drives the connecting ends 322 of the respective locking portions 32 to rotate in a second preset direction, so that the respective locking portions 32 are in an open state. With such a structural arrangement, through the lifting movement of the connecting portion 33, the switching between the open state and the retracted state of the locking portion 32 can be conveniently controlled, improving the flexibility of the locking structure 3. And the lifting movement of the connecting portion 33 can ensure the stable conversion of the locking portion 32 between the open state and the retracted state, improving the stability of the locking structure 3. At the same time, the lifting movement of the connecting portion 33 can quickly realize the opening and retraction of the locking portion 32, improving the tire removal efficiency. In addition, through the rotatable connection between the connecting portion 33 and the locking portion 32, the contact and friction between the locking portion 32 and other components can be reduced, reducing wear and tear.

[0045] Wherein, the first preset direction mentioned above refers to the rotation in a preset direction, which can make the locking end 321 away from the lower steel ring. The second preset direction mentioned above refers to the rotation in a preset direction, which can make the locking end 321 close to the lower steel ring.

[0046] Optionally, when the respective locking portions 32 are in the retracted state, the connecting portion 33 rises relative to the mounting bracket 31, and then drives the connecting ends 322 of the locking portions 32 to rotate inward (that is, drives the locking portions 32 to rotate in the first preset direction), thereby driving the locking ends 321 of the locking portions 32 to move in a direction away from the lower steel ring. When the respective locking portions 32 are in the open state, the connecting portion 33 descends relative to the mounting bracket 31, and then drives the connecting ends 322 of the locking portions 32 to rotate outward (that is, drives the locking portions 32 to rotate in the second preset direction), thereby driving the locking ends 321 of the locking portions 32 to move in a direction close to the lower steel ring.

[0047] Further, as Figure 1 、 Figures 3 to 7As shown, a limiting groove 323 is provided on the side wall of each locking part 32, and the limiting groove 323 extends along a preset track; the locking structure 3 also includes: a plurality of connecting shafts 34, the plurality of connecting shafts 34 are arranged one by one with the plurality of locking parts 32, each connecting shaft 34 is inserted into the corresponding limiting groove 323, and each locking part is connected to the mounting bracket 31 through the corresponding connecting shaft 34; the limiting groove 323 is used to limit the movement direction of the locking part 32. With such a structural setting, the movement direction of the locking part 32 can be limited by the cooperation of the limiting groove 323 and the connecting shaft 34, so as to ensure that the locking part 32 moves along the preset track, thereby accurately controlling the movement path of the locking part 32, ensuring that the locking end 321 can be accurately clamped on the edge of the center hole of the lower steel ring or detached from it, thereby improving the stability of the locking structure 3. In addition, the design of the limiting groove 323 can ensure the reliable conversion of the locking part 32 between the open state and the retracted state, thereby improving the reliability of the locking structure 3. At the same time, through the cooperation between the limiting groove 323 and the connecting shaft 34, the switching of the locking portion 32 between the open state and the retracted state can be effectively controlled, thereby improving the flexibility of the locking structure 3.

[0048] The preset trajectory mentioned above refers to the predetermined path followed by the locking portion 32 during the movement.

[0049] Optionally, the locking process of the locking part 32 is as follows: when the lower steel ring needs to be locked, the connecting part 33 descends relative to the mounting bracket 31, thereby driving the connecting end 322 of each locking part 32 to rotate outward, so that the locking end 321 of each locking part 32 extends outward along a preset trajectory (that is, the locking end 321 of each locking part 32 moves toward the lower steel ring), and finally the locking structure 3 is locked and connected with the lower steel ring.

[0050] Optionally, the unlocking process of the locking part 32 is as follows: when the locking structure needs to be separated from the lower steel ring, the connecting part 33 rises relative to the mounting bracket 31, and as the connecting part 33 rises, the connecting ends 322 of each locking part 32 are driven to rotate inward, and then the locking ends 321 of each locking part 32 shrink inward along a preset trajectory (that is, the locking ends 321 of each locking part 32 move inwardly away from the lower steel ring), thereby separating the locking structure 3 from the lower steel ring, and finally placing the locking structure 3 in an avoidance position.

[0051] Specifically, the locking structure 3 also includes: a first driving component 35, the first driving component 35 is arranged on the ejection structure 2, and the driving end of the first driving component 35 is located in the connecting hole 311; the driving end of the first driving component 35 is drivingly connected to the connecting part 33 to drive the connecting part 33 to rise or fall relative to the mounting bracket 31.

[0052] Preferably, the first driving assembly 35 is a first cylinder.

[0053] In this embodiment, as Figure 5 shown, the ejection structure 2 includes a fixed seat 21 and a tray 22. The fixed seat 21 is vertically liftably arranged on the mounting seat 1; the tray 22 is arranged above the fixed seat 21; the tray 22 is used to abut against the lower steel ring so that the tire is located on the tray 22; wherein, a placement space is formed between the fixed seat 21 and the tray 22, and at least part of the locking structure 3 is located in the placement space. With such a structural arrangement, through the lifting movement of the fixed seat 21 in the vertical direction, the stable contact between the tray 22 and the lower steel ring can be ensured, and the stability of the ejection structure 2 is improved. The lifting movement of the fixed seat 21 can quickly eject the tire from the lower die cavity, improving the production efficiency. At the same time, by arranging the tray 22, a supporting effect can be achieved, ensuring that the tire is smoothly ejected from the lower die cavity, improving the quality of the tire, and avoiding product defects caused by improper demolding. And it reduces the friction between the tire and the lower mold, improving the stability.

[0054] Furthermore, as Figure 5 shown, the ejection structure 2 further includes a plurality of support rods 24. The plurality of support rods 24 are arranged at intervals along the circumferential direction of the fixed seat 21. The fixed seat 21 is connected to the tray 22 through the plurality of support rods 24, so that the tray 22 is located above the fixed seat 21.

[0055] Furthermore, the first driving body of the first driving assembly 35 is installed on the fixed seat 21, and the first driving body of the first driving assembly 35 is located in the placement space. The first driving rod of the first driving assembly 35 moves towards the connecting part 33, and the first driving rod of the first driving assembly 35 passes through the tray 22 and is located in the communication hole 311 of the mounting bracket and is connected to the connecting part 33, so that the first driving assembly 35 drives the connecting part 33 to rise or fall relative to the mounting bracket 31.

[0056] Specifically, as Figure 1 and Figure 2 shown, the ejection structure 2 further includes a second driving assembly 23. The second driving assembly 23 is installed on the mounting seat 1, and the driving end of the second driving assembly 23 is connected to the fixed seat 21 to drive the fixed seat 21 to rise or fall in the vertical direction through the second driving assembly 23.

[0057] Furthermore, the second driving body of the second driving assembly 23 is located below the mounting seat 1, and the driving end of the second driving assembly 23 passes through the mounting seat 1 and is connected to the fixed seat 21.

[0058] The present utility model further provides a tire loading and unloading device for a vulcanizer, as Figure 8 and Figure 9As shown in the figure, the tire loading and unloading device includes: a placement table 100, a push-pull die device 200, and a demolding device. The placement table 100 is movably arranged along the height direction of the vulcanizer. The placement table 100 is provided with a positioning through hole that extends along the height direction of the vulcanizer. The push-pull die device 200 is movably arranged on the placement table 100 and is used to move the lower die from the vulcanizer to the placement table 100 so that the lower steel ring of the lower die is oppositely arranged with the positioning through hole; or to move the lower die from the placement table 100 back to the vulcanizer. The demolding device is the demolding device of the above embodiment. The demolding device is located below the positioning through hole, and the top end of the mounting seat 1 of the demolding device is fixedly connected to the bottom surface of the placement table 100 relatively. At least part of the demolding device is telescopically arranged in the positioning through hole along the extending direction of the positioning through hole. With such a structural arrangement, the movable design of the placement table 100 enables the device to adapt to vulcanizers of different heights, improving the flexibility of the tire loading and unloading device. By arranging the push-pull die device 200 on the placement table 100, the lower die can be quickly moved from the vulcanizer to the placement table 100 or from the placement table 100 back to the vulcanizer, improving the efficiency of tire loading and unloading. And when the push-pull die device 200 moves the lower die from the vulcanizer to the placement table 100 and moves the lower die to make the lower steel ring of the lower die oppositely arranged with the positioning through hole, the accuracy of subsequent demolding operations can be effectively improved. Thus, by arranging the placement table 100, the push-pull die device 200, and the demolding device, not only the flexibility and stability of the tire loading and unloading device are improved, but also the efficiency and reliability of the entire tire loading and unloading process are improved. And it helps to improve production efficiency and product quality, while reducing operation risks and costs.

[0059] Further, the ejecting structure 2 and the locking structure 3 of the demolding device are oppositely arranged with the positioning through hole, and at least part of the ejecting structure 2 and at least part of the locking structure 3 of the demolding device are telescopically arranged in the positioning through hole along the extending direction of the positioning through hole.

[0060] Specifically, the tire loading and unloading device further includes: a tire unloading device 300. The tire unloading device 300 is movably arranged and is used to clamp the tire when the demolding device ejects the vulcanized tire from the lower die cavity of the lower die and drive the tire to move to a designated position for tire unloading.

[0061] 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:

[0062] First, the placement table 100 is moved to one side of the workbench of the vulcanizer, so that the placement table 100 is arranged opposite to the workbench of the vulcanizer; then, the push-pull mold device 200 moves relative to the placement table 100 to the side of the placement table 100 close to the workbench of the vulcanizer, and then the push-pull mold device 200 is connected to the lower mold of the vulcanizer mold; after the connection, the lower mold is moved out of the vulcanizer and onto the placement table 100, and the lower mold is driven to move to the specified position, so that the lower steel ring of the lower mold is arranged opposite to the positioning through hole.

[0063] The vulcanization mold can be opened at the workbench of the vulcanizer, specifically, the upper mold is separated from the lower mold. Alternatively, the vulcanization mold is first moved to the placement table 100 as a whole by a push-pull mold device, and the vulcanization mold is driven to move to a specified position, and then the mold is opened to separate the upper mold from the lower mold, and then the demoulding process is performed after separation.

[0064] Secondly, the demoulding device performs a demoulding process: first, the ejection structure 2 rises relative to the mounting seat 1, so that the ejection structure 2 passes through the positioning through hole and the center hole of the shell of the lower mold in sequence and abuts against the bottom surface of the lower steel ring. After abutting, the ejection structure 2 continues to rise against the lower steel ring and the tire, and rises to a specified position. After reaching the specified position, the tire is separated from the shell of the lower mold, so that the tire and the lower steel ring are located above the shell of the lower mold. Among them, when the ejection structure 2 passes through the center hole of the shell of the lower mold and abuts against the bottom surface of the lower steel ring, at least part of the locking structure 3 passes through the shell of the lower mold and the center hole of the lower steel ring in sequence and is located above the lower steel ring. At this time, the locking structure 3 is in an avoidance position. Secondly, after the ejection structure 2 rises to the specified position (that is, after the ejection structure 2 ejects the tire from the lower mold cavity of the lower mold through the lower steel ring), the locking portion 32 of the locking structure 3 moves toward the lower steel ring so that the locking structure 3 is locked and connected with the lower steel ring, and then the locking structure 3 is in a locked position. Thereby locking the lower steel ring on the demoulding device.

[0065] Once again, after the tire is pushed out, the tire unloading device 300 moves to the tire, and then the tire unloading device 300 clamps the tire. After the tire unloading device 300 clamps the tire, it drives the tire to move. At this time, the lower steel ring is locked on the demoulding device, so that the lower steel ring and the tire are separated.

[0066] Finally, after the separation is completed, the tire unloading device 300 drives the tire to move to the designated position for unloading. At the same time, the ejection structure 2 descends with the lower steel ring, and when the lower steel ring is placed in the shell of the lower mold, the locking portion 32 of the locking structure 3 moves in a direction away from the lower steel ring, and the locking structure 3 switches from the locking position to the avoidance position, so that as the ejection structure 2 continues to descend, the locking structure 3 is smoothly separated from the center hole of the lower steel ring and the center hole of the lower mold, and then at least part of the locking structure 3 is located in the positioning through hole.

[0067] Furthermore, at least a portion of the locking structure 3 is located above the ejection structure.

[0068] Furthermore, the lower mold also has a shell, a center hole is provided at the bottom of the shell, a lower mold cavity is provided in the shell, a lower steel ring is located in the lower mold cavity, a center hole is also provided on the lower steel ring, and the center hole of the shell is concentric with the center hole of the lower steel ring. When the vulcanized tire needs to be separated from the shell of the lower mold, the ejection structure 2 moves toward the lower mold, passes through the center hole of the shell of the lower mold and abuts against the bottom surface of the lower steel ring, so that as the ejection structure 2 continues to rise, the ejection structure 2 ejects the tire through the lower steel ring, so that the tire is located above the shell of the lower mold, and the tire is separated from the shell of the lower mold.

[0069] Optionally, the working process of the demoulding device is:

[0070] First, the ejection structure 2 rises relative to the mounting seat 1, so that the ejection structure 2 passes through the center hole of the shell of the lower mold and abuts against the bottom surface of the lower steel ring. After abutting, the ejection structure 2 continues to rise against the lower steel ring and the tire, and rises to a specified position. After reaching the specified position, the tire is separated from the shell of the lower mold, so that the tire and the lower steel ring are located above the shell of the lower mold. Among them, when the ejection structure 2 passes through the center hole of the shell of the lower mold and abuts against the bottom surface of the lower steel ring, at least part of the locking structure 3 passes through the shell of the lower mold and the center hole of the lower steel ring in sequence and is located above the lower steel ring. At this time, the locking structure 3 is in an avoidance position.

[0071] Secondly, when the ejection structure 2 rises to the specified position (i.e., after the ejection structure 2 ejects the tire through the lower steel ring), at least part of the locking structure 3 moves toward the lower steel ring so that the locking structure 3 is locked and connected with the lower steel ring, and then the locking structure 3 is in the locked position. Thus, the lower steel ring is locked on the demoulding device, and the tire is separated from the lower steel ring when the tire is removed.

[0072] Finally, when the lower steel ring is separated from the tire, the ejection structure 2 descends with the lower steel ring, and when the lower steel ring is placed in the shell of the lower mold, at least part of the locking structure 3 moves in the direction away from the lower steel ring, and the locking structure 3 switches from the locking position to the avoidance position, so that as the ejection structure 2 continues to descend, the locking structure 3 can be smoothly separated from the center hole of the lower steel ring and the center hole of the lower mold. Alternatively, when the operator or the manipulator holds the tire tightly to remove the tire, the ejection structure 2 descends with the lower steel ring and the locking structure 3 at the same time, so that the tire and the lower steel ring are easier to separate. Alternatively, after the tire is separated from the lower steel ring, and the ejection structure 2 has not yet descended, the locking structure 3 immediately switches from the locking position to the avoidance position.

[0073] The utility model provides a demoulding device, which is used to eject the vulcanized tire from the lower die cavity of the lower die. The demoulding device comprises: a mounting seat 1, an ejecting structure 2 and a locking structure 3. The mounting seat 1 is located below the lower die; the ejecting structure 2 is arranged on the mounting seat 1 so as to be vertically liftable; the ejecting structure 2 is used for abutting against the lower steel ring of the lower die, and the ejecting structure 2 is used to eject the tire from the lower die cavity through the lower steel ring; the locking structure 3 is arranged on the ejecting structure 2, and at least part of the locking structure 3 is movably arranged relative to the ejecting structure 2; the locking structure 3 has a locking position and an avoidance position. When the locking structure 3 is in the locking position, at least part of the locking structure 3 moves towards the direction of the lower steel ring, so that the locking structure 3 is locked and connected with the lower steel ring, so as to separate the lower steel ring from the tire when taking the tire; when the locking structure 3 is in the avoidance position, at least part of the locking structure 3 moves towards the direction away from the lower steel ring, so that the locking structure 3 is separated from the lower steel ring.

[0074] It can be seen that for the demoulding device provided by the present utility model, by simply arranging the mounting base 1, the ejection structure 2 and the locking structure 3, and the ejection structure 2 is arranged on the mounting base 1 so as to be vertically liftable, and then the ejection structure 2 ejects the tire from the lower die cavity by contacting with the lower steel ring. Thus, it can be seen that such a design can quickly realize the demoulding of the tire and improve the production efficiency. Moreover, by the contact between the ejection structure 2 and the lower steel ring, it can be ensured that the tire is smoothly ejected from the lower die cavity, avoiding tire damage or deformation caused by unstable ejection. At the same time, the design of the ejection structure 2 can also reduce the friction between the tire and the lower die, reducing wear and damage caused by excessive force. Through the precise control of the ejection structure 2, the manual intervention in the operation process can be reduced, the operation risk is lowered, and the safety is improved. Also, by ensuring that the tire is smoothly ejected from the lower die cavity, the quality of the tire can be improved, avoiding product defects caused by improper demoulding. In addition, the locking structure 3 is arranged on the ejection structure 2, and then the ejection structure 2 drives the locking structure 3 to move towards the lower die, so that when the ejection structure 2 abuts against the lower steel ring of the lower die, at least part of the locking structure 3 passes through the lower die and is located above the lower steel ring, and then at least part of the locking structure 3 moves towards the lower steel ring, so that the locking structure 3 is locked and connected with the lower steel ring. Thus, when the ejection structure 2 ejects the tire from the lower die cavity through the lower steel ring and the tire is taken, the lower steel ring can be locked on the demoulding device through the locking structure 3, so that the lower steel ring is separated from the tire. When it is not necessary to lock the lower steel ring, at least part of the locking structure 3 moves towards the direction away from the lower steel ring, so that the locking structure 3 is separated from the lower steel ring. Thus, it can be seen that by arranging the locking structure 3, it can effectively prevent the lower steel ring from being taken away together during the tire-taking process, improving the safety of the operation. And it ensures that the lower steel ring stays stably in place during the tire-taking process, improving the stability of the whole tire-removing process. Also, the reliable locking of the locking structure 3 can reduce the failure rate caused by the non-separation of the lower steel ring. The operation difficulty of the operator is reduced, making the tire-removing process more convenient. At the same time, by ensuring the effective separation of the lower steel ring and the tire, the quality of the tire can be improved, avoiding product defects caused by improper tire removal. This demoulding device effectively solves the technical problem in the prior art that during the tire-removing process, the demoulding device cannot effectively lock the lower steel ring, resulting in the lower steel ring being easily taken away together by the manipulator.
