Description

Technical Field

[0001] This utility model relates to the field of component spraying technology, and in particular to a spare tire discharge device for rubber tire vulcanization mechanisms. Background Technology

[0002] The backup tire discharge device in a rubber tire vulcanizing machine is an emergency or auxiliary device for the main discharge device in the tire vulcanizing machine production process. Its core function is to facilitate the removal of the finished vulcanized tires. Essentially, it mitigates the risk of main device failure through backup design. Tire vulcanization is a critical process for final product shaping. Unvulcanized tire blanks need to be processed by molds under high temperature and pressure to form finished products. Afterward, the tires are removed by the main discharge device and proceed to the next stage, such as inspection and trimming. This backup device is a crucial alternative when the main device fails. In the event of mechanical jamming, motor damage, or control component malfunction, the device quickly discharges tires via an independent power unit, preventing the finished products from cooling inside the mold. However, it can cause adhesion and equipment downtime. When the main unit needs maintenance and repair, it can be used as a temporary replacement to ensure that the vulcanizing machine, vulcanization and discharge cycle are not interrupted. At the same time, it can prevent finished products from being stuck and causing scratches on high-value and high-precision molds, as well as the problem of scrap products such as insufficient glue and bulging due to uneven cooling. From a value perspective, it can reduce the downtime caused by the failure of the main unit from several hours to a few minutes, greatly reduce the loss of production capacity, extend the life of molds, reduce maintenance costs, reduce scrap rate, and avoid the risk of burns and squeezing when manually reaching into the high-temperature mold to remove tires. It is indispensable for mid-to-high-end tire production lines that pursue production capacity stability, and ultimately achieve the goals of continuous production, controllable costs, and safety and compliance.

[0003] The spare tire unloading device for rubber tire vulcanization mechanisms is an integrated device designed for emergency tire removal, equipment redundancy, and safe and reliable operation. The power and drive components include an independent three-phase asynchronous motor, a backup battery pack or diesel generator, and a manual high-pressure hydraulic pump, covering power needs across all scenarios: electric, backup electric, and manual. The tire removal mechanism uses a lifting base plate and a horizontally movable push plate driven by a hydraulic cylinder or electric push rod to remove the tire, and relies on a chain conveyor belt and guide chutes for tire transfer. The control components employ an independent PLC and a network of limit, pressure, and temperature sensors, supporting local manual and remote operation and featuring an emergency stop button to ensure precise control. Safety protection and lubrication components include a hydraulic relief valve. The device features a motor thermal relay, infrared anti-pinch device, and high-temperature resistant coating, along with an automatic lubrication pump, manual grease nipple, and quick-release module. It balances safety and ease of maintenance. Structurally, it adopts a modular frame with a steel structure support and protective shell, providing both embedded and external installation options. The backup and redundancy design achieves redundancy of key components through dual power sources and dual-path sensors. One-button switching is achieved through mechanical interlocks to avoid conflicts between the main and backup devices and ensure seamless replacement. This device integrates mechanical, electrical, and hydraulic technologies, with power redundancy, independent control, and multiple protections as its core. It can efficiently and safely remove tires when the main discharge device fails, protecting high-value molds and finished products and maintaining the continuous operation of the tire production line.

[0004] Some spare tire discharge devices for rubber tire vulcanizing machines have several drawbacks. First, they produce only a limited variety of products, with fixed designs for the actuator size and auxiliary conveying device specifications. They can only accommodate tires of specific diameters and widths. If it is necessary to switch to producing different tire specifications, the existing actuator cannot be flexibly adjusted, requiring the replacement of the entire set of adaptable components, making it difficult to meet the emergency discharge needs of multiple tire specifications. Second, the mold replacement process is cumbersome. When changing molds, the connection structure between the device and the original mold must be manually disassembled first. Then, the height of the lifting base plate must be manually calibrated to match the cavity depth of the new mold, and the ejection distance of the movable push plate must be readjusted. At the same time, professional personnel must re-enter the sensor thresholds corresponding to the new mold for program debugging, which seriously affects the efficiency of production line switching. Therefore, a spare tire discharge device for rubber tire vulcanizing machines is proposed to solve the above problems. Utility Model Content

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0037] A spare tire discharge device for a rubber tire vulcanization mechanism, as described in the following reference. Figures 1 to 3 The device includes a base plate 1, which is the core load-bearing foundation component. Through its rigid structure, it supports all the upper components, ensuring the overall stability of the device during tire discharge, mold replacement, and height adjustment. This prevents components from shifting due to instability at the bottom, which could affect operational accuracy or cause equipment damage. It also provides reliable installation and movement space for each functional component. A support slide column 2 is fixedly connected to the top of the base plate 1. This fixed connection forms a rigid support between the support slide column 2 and the base plate 1. The support slide column 2 serves as the installation carrier for the subsequent top support components. Through its own structure, it stably supports the top support components above the base plate 1. At the same time, it provides a sliding and limiting foundation for the subsequent height adjustment mechanism, ensuring that the mechanism can adjust its position along a preset trajectory.

[0038] Specifically, the base plate 1 is the core load-bearing foundation component of the device. Its rigid structure supports all the upper components, ensuring the overall stability of the device during tire discharge, mold replacement, and height adjustment. This prevents components from shifting due to instability at the bottom, affecting operational accuracy or causing equipment damage. It provides reliable installation and movement space for each functional component. The support slide column 2 serves as the installation carrier for the subsequent top support components. Through its own structure, it stably mounts the top support components above the base plate 1, providing a sliding and limiting foundation for the subsequent height adjustment mechanism, ensuring that the mechanism can adjust its position along a preset trajectory.

[0039] A top cover 6 is fixedly connected to the top of the supporting slide column 2, forming an integral unit with the supporting slide column 2. The bottom of the top cover 6 provides an installation position for the subsequent slide rail components, and the top provides a stable installation platform for the subsequent power components. It withstands the reaction force generated by the power components during operation through its own structural strength, preventing the components from shaking and ensuring the action accuracy of the subsequent mold changing mechanism. A cylinder 7 is installed on the top of the top cover 6. The cylinder 7 is the power source for the subsequent quick mold changing mechanism. The extension and retraction of the drive end drives the quick mold changing mechanism to move up and down. Pushing it down facilitates mold changing operations, and retracting it upwards assists in the removal of the old mold, providing power support for mold assembly and disassembly, ensuring efficient and labor-saving mold changing operations. A quick changing mechanism 3 is fixedly connected to the drive end of the cylinder 7, and the fixed connection allows the quick changing mechanism 3 to move synchronously with the drive end of the cylinder 7. The core function of the quick changing mechanism 3 is to realize the quick assembly and disassembly of the mold. The internal components are linked to release or lock the mold fixation, reducing mold change time, adapting to the production needs of different sized tires, and improving the equipment's versatility.

[0040] Specifically, the bottom of the top cover 6 provides an installation location for subsequent slide rail components, while the top serves as a stable installation platform for subsequent power components. Its structural strength allows it to withstand the reaction force of the power components during operation, preventing component swaying and ensuring the accuracy of the subsequent mold-changing mechanism. The cylinder 7, as the power source for the subsequent quick mold-changing mechanism, moves the mechanism up and down through the extension and retraction of its drive end. Pushing downwards facilitates mold replacement operations, while retracting upwards assists in the removal of the old mold, providing power support for mold assembly and disassembly, making mold changing more efficient and labor-saving. The core function of the quick-change mechanism 3 is to achieve rapid mold assembly and disassembly. It uses the linkage of internal components to release or lock the mold's fixed state, shortening mold change time, adapting to the production needs of tires of different sizes, and improving the equipment's versatility.

[0041] A slide rail column 5 is fixedly connected to the bottom of the top cover 6, forming an integral unit with the top cover 6. The slide rail column 5 provides sliding guidance for subsequent components, restricting the movement trajectory of the mechanism and ensuring that its height is adjusted only in the vertical direction. This prevents misalignment that could lead to inaccurate mold release agent spraying and ensures precise height adjustment. A mold release agent height adjustment mechanism 4 is slidably connected inside the slide rail column 5. This slidable connection allows the mold release agent height adjustment mechanism 4 to slide up and down along the inside of the slide rail column 5. The core function of this mechanism is to adjust the height of the mold release agent spraying component to adapt to the spraying requirements of tires of different sizes, ensuring that the mold release agent is accurately sprayed onto the tire surface. Simultaneously, a locking structure secures the adjusted height. To prevent displacement during operation, the quick change mechanism 3 includes a push plate 31, which is the main supporting component of the quick change mechanism 3. It is connected to the drive end of the cylinder 7 at the top and moves up and down synchronously with the cylinder 7, providing installation and operation space for internal operating components and transmission components, while transmitting the power of the cylinder 7 to assist in the disassembly and assembly of the mold. The top of the push plate 31 is installed at the drive end of the cylinder 7. This installation method ensures that the push plate 31 can stably extend and retract with the drive end of the cylinder 7. The power of the cylinder 7 can be directly transmitted to the push plate 31, driving the entire quick change mechanism 3 to move up and down, providing power for position adjustment during mold change and avoiding the inconvenience of manually moving the mold.

[0042] Specifically, the slide rail column 5 provides guidance for the subsequent sliding parts, limiting their movement path and ensuring that the height of the parts can only be adjusted in the vertical direction. This prevents misalignment of the release agent spraying due to positional deviation and ensures the accuracy of height adjustment. The release agent height adjustment mechanism 4 can adjust the height of the release agent spraying parts to meet the spraying needs of tires of different sizes, allowing the release agent to accurately cover the tire surface. It can also fix the adjusted height through a locking structure to prevent displacement during operation. The push plate 31, as the main load-bearing component of the quick change mechanism 3, moves up and down synchronously with the cylinder 7, providing installation and movement space for internal operating parts, transmission parts, etc. At the same time, it transmits the power of the cylinder 7 to assist in the mold assembly and disassembly, eliminating the need to manually move the mold and reducing operational inconvenience.

[0043] The push plate 31 has an internal sliding connection to a toggle post 32. This sliding connection allows the toggle post 32 to be pulled outward or returned inward along the inside of the push plate 31. The toggle post 32 is a trigger component for quick mold changing. By pulling it externally, it drives the subsequent locking components to move, releasing the mold from its fixed state. This operation is convenient and does not require complex tools. A locking block 33 is fixedly connected to the bottom of the toggle post 32. This fixed connection allows the locking block 33 to move synchronously with the toggle post 32. The locking block 33 is the core transmission component for mold fixing. As it moves with the toggle post 32, it drives the subsequent fixing components to disengage from or insert into the corresponding mating components, realizing the unlocking or locking of the mold. It is the key to connecting the operating components and the fixing components. In this process, a connecting post 34 is fixedly connected inside the locking block 33. The fixed connection allows the connecting post 34 to move synchronously with the locking block 33. The connecting post 34 is the actuator for fixing the mold. When it is inserted into the corresponding mating part, it restricts the movement of the mating part through engagement, thereby fixing the mold. When it is disengaged from the mating part, the fixing is released, allowing the mold to be disassembled. A sliding post 35 is fixedly connected to the front end of the locking block 33. The fixed connection allows the sliding post 35 to move synchronously with the locking block 33. The sliding post 35 slides inside the push plate 31, providing guidance for the movement of the locking block 33. This ensures that the locking block 33 drives the connecting post 34 to accurately align with the corresponding mating part, avoiding fixing failure or disassembly difficulties due to misalignment.

[0044] Specifically, the actuating column 32 can be pulled outward or reset inward inside the push plate 31, serving as the operation trigger component for quick mold changing. When pulled, it can drive the subsequent locking component to release the mold fixation. The operation is convenient and requires no complicated tools. The locking block 33 moves synchronously with the actuating column 32 and is the core transmission component for mold fixation. When it moves, it will drive the subsequent fixing component to disengage or insert into the corresponding mating component, realizing the unlocking or locking of the mold. It plays a key role in connecting the operating component and the fixing component. The connecting column 34 moves synchronously with the locking block 33 and is the execution component for mold fixation. When inserted into the corresponding mating component, it restricts its movement through engagement to fix the mold. When disengaged, it releases the fixation to facilitate mold disassembly and assembly. The sliding column 35 moves synchronously with the locking block 33 and slides inside the push plate 31, providing guidance for the movement of the locking block 33 and ensuring that the connecting column 34 can be accurately aligned with the corresponding mating component, avoiding fixation failure or disassembly and assembly difficulties due to misalignment.

[0045] A spring 37 is sleeved on the outside of the sliding column 35. The rear end of the spring 37 is fixed inside the push plate 31, while the front end moves with the sliding column 35. Its core function is to provide automatic reset power for the locking block 33. When the actuating column 32 is pulled, the spring 37 is compressed and stores force. When the actuating column 32 is released, the spring 37 rebounds and pushes the locking block 33 to reset, causing the connecting column 34 to insert into the corresponding mating part, thus achieving automatic mold locking. The rear end of the spring 37 is fixedly connected inside the push plate 31. This fixing method provides a stable force base for the spring 37, ensuring that the spring 37 will not shift during the extension and retraction process. This ensures that the reset action of the locking block 33 is accurate and stable, and avoids the connection column 34 from being unable to be accurately inserted due to spring displacement. Corresponding to the mating components, the front end of the sliding column 35 is fixedly connected to a limit ring 36. The fixed connection allows the limit ring 36 and the sliding column 35 to move synchronously. The core function of the limit ring 36 is to limit the maximum reset distance of the locking block 33, preventing the locking block 33 from being pushed excessively when the spring 37 rebounds, which would cause the connecting column 34 to insert too deeply into the corresponding mating component or the locking block 33 to disengage from the push plate 31. This ensures the integrity of the mechanism structure and the reliability of its operation. The rear end of the locking block 33 is slidably connected to a processing component 38. The slidable connection allows the processing component 38 to be disassembled and assembled with the locking or unlocking action of the locking block 33. The processing component 38 is the core component of tire forming. It can be quickly replaced by cooperating with the quick change mechanism 3 to adapt to the production of tires of different sizes. It is the key to the equipment to achieve multi-specification production.

[0046] Specifically, spring 37 is fitted outside the sliding column 35, with its rear end fixed inside the push plate 31 and its front end moving with the sliding column 35. Its core function is to provide automatic reset power for the locking block 33. When the actuating column 32 is pulled, it is compressed and stores force. After being released, it rebounds and pushes the locking block 33 to reset, causing the connecting column 34 to insert into the corresponding mating component to achieve automatic mold locking. The fixed rear end provides a stable force base to prevent displacement during extension and retraction, ensuring accurate reset of the locking block 33. The limiting ring 36 is at the front end of the sliding column 35 and moves synchronously with it. Its core function is to limit the maximum reset distance of the locking block 33, preventing the spring 37 from excessively pushing the locking block 33 when it rebounds, and preventing the connecting column 34 from inserting too deeply or the locking block 33 from disengaging from the push plate 31. This ensures the integrity of the mechanism structure and reliable operation. The processing component 38 is slidably connected to the rear end of the locking block 33 and can be disassembled and assembled with the locking or unlocking action of the locking block 33. It is a core component of tire forming. With the quick change mechanism 3, it can be quickly changed to adapt to the production of tires of different sizes, which is the key to the equipment's multi-specification production.

[0047] The processing component 38 includes a locking post 381, which is the connecting part between the processing component 38 and the quick-change mechanism 3. Externally, it slides with the locking block 33, and internally, it provides insertion space for the connecting post 34. The insertion of the connecting post 34 secures the processing component 38, and disassembly allows for its removal. It is a core component for mold fixing. The locking post 381 is externally slidably connected to the rear end of the locking block 33. This sliding connection ensures that the processing component 38 can be smoothly installed onto the locking block 33. Simultaneously, the contact surface between the locking post 381 and the locking block 33 restricts the radial movement of the processing component 38, preventing wobbling during mold operation and ensuring tire molding accuracy. The connecting post 34 is externally slidably connected to the locking post 381. Inside 81, this sliding connection allows the connecting post 34 to smoothly insert into or detach from the slotting post 381. When inserted, it engages and fixes the slotting post 381, thereby fixing the mold. When detached, it releases the fixation, facilitating the assembly and disassembly of the processing component 38. At the same time, the tight fit between the connecting post 34 and the slotting post 381 ensures that there is no loosening after fixing. The bottom of the slotting post 381 is fixedly connected to the top mold 382. The fixed connection makes the top mold 382 and the slotting post 381 form an integral whole. The top mold 382 is the direct execution component for tire vulcanization molding. Its internal cavity is adapted to the tire size. It can be quickly changed through cooperation with the quick change mechanism 3. Different specifications of top mold 382 can be replaced according to production needs to produce tire products of various sizes.

[0048] Specifically, the clamping post 381 is a key component connecting the processing component 38 and the quick-change mechanism 3. It slides with the clamping block 33 externally and reserves space for the insertion of the connecting post 34 internally. When the connecting post 34 is inserted, it can fix the processing component 38, and when it is detached, it can be disassembled. At the same time, the contact surface with the clamping block 33 can restrict the radial movement of the processing component 38, prevent the mold from shaking during operation, and ensure the tire forming accuracy. The connecting post 34 can be smoothly inserted or detached inside the clamping post 381. When inserted, it fixes the clamping post 381 by biting, thereby fixing the mold. When detached, it releases the fixation, which is convenient for the processing component 38 to be disassembled and assembled. The tight fit between the two can also ensure that there is no loosening after fixing. The top mold 382 and the clamping post 381 form an integral part and are the direct execution component for tire vulcanization molding. The internal cavity is adapted to the corresponding tire size. With the quick-change mechanism 3, quick replacement can be achieved. Different specifications of the top mold 382 can be replaced according to production needs, thereby producing tire products of various sizes.

[0049] Reference Figure 1 , Figure 2 and Figure 4The release agent height adjustment mechanism 4 includes a slider 41, which is the main supporting component of the release agent height adjustment mechanism 4. It is externally slidably connected to the slide rail column 5 and internally connected to the operating components, providing the installation base for the entire mechanism. It slides along the slide rail column 5 and the supporting slide column 2, driving the release agent spraying component to adjust the height. It is the core carrier for height adjustment. The external slider 41 is slidably connected to the inside of the slide rail column 5. The sliding connection allows the slider 41 to slide up and down along the inside of the slide rail column 5. The slide rail column 5 provides vertical guidance for the slider 41, ensuring that the slider 41 drives the release agent spraying component to adjust the height only along the preset trajectory, avoiding left and right deviation that would cause inaccurate spraying position, and ensuring the accuracy of height adjustment.

[0050] Specifically, slider 41 is the main supporting component of the release agent height adjustment mechanism 4. It can be connected to the operating component internally and can slide and cooperate with the slide rail column 5 externally, providing the installation base for the entire mechanism. At the same time, it will slide along the slide rail column 5 and the supporting slide column 2, driving the release agent spraying component to adjust the height. It is the core carrier for height adjustment. The slide rail column 5 can also provide vertical guidance for slider 41, ensuring that slider 41 drives the spraying component to adjust the height only along the preset trajectory, avoiding left and right deviation that would cause inaccurate spraying position, and ensuring the accuracy of height adjustment.

[0051] A push block 42 is slidably connected inside the slider 41. This slidable connection allows the push block 42 to move up and down within the slider 41. The push block 42 is the trigger for height adjustment; when squeezed downwards, it releases the height lock by engaging the subsequent transmission components. When released, it resets under the action of a spring, achieving height locking. Operation is convenient and requires no additional tools. A second spring 43 is fixedly connected to the bottom of the push block 42, ensuring synchronized movement between the spring 43 and the push block 42. The bottom of the second spring 43 is fixed inside the slider 41, and its core function is to provide automatic reset power for the push block 42. When the push block 42 is squeezed, the second spring 43 is compressed and stores force; when released, the spring 43 rebounds, pushing the push block 42 back to its original position, thus achieving height locking. The subsequent components achieve height locking. The bottom of the second spring 43 is fixedly connected to the inside of the slider 41. This fixing method provides a stable force base for the second spring 43, ensuring that the second spring 43 will not shift during the extension and retraction process. This allows the reset action of the push block 42 to be accurate, avoiding the locking component from failing to make reliable contact due to spring offset, thus ensuring the height locking effect. The external rotatable connection of the push block 42 is a lever arm 44. The rotatable connection allows the lever arm 44 to rotate flexibly around the push block 42. The lever arm 44, as a lever transmission component, converts the up and down movement of the push block 42 into the vertical sliding of the subsequent sliding component, realizing the power transmission of the operation end action, transmission, and locking end action. It is the key transmission link for height locking and unlocking.

[0052] Specifically, the push block 42 is the operation trigger component for height adjustment. When squeezed downwards, it can drive the subsequent transmission component to release the height lock. After being released, it can reset under the action of the spring to achieve height locking. The operation is convenient and does not require additional tools. The core function of the spring 43 is to provide automatic reset power for the push block 42. When the push block 42 is squeezed, it is compressed and stored. After being released, it rebounds and pushes the push block 42 to reset, thereby driving the subsequent component to complete the height lock. Its stable force base can ensure accurate reset action and avoid the locking effect being affected by deviation. The lever arm 44, as a lever transmission component, can convert the up and down movement of the push block 42 into the vertical sliding of the subsequent sliding component, realizing the power transmission between the operation end, the transmission link and the locking end. It is the key transmission link for height locking and unlocking.

[0053] A sliding post 45 is internally connected to the lever arm 44. This sliding connection allows the sliding post 45 to slide within the lever arm 44 and move up and down with the rotation of the lever arm 44. The sliding post 45 is the actuator for the locking action. When it moves upward, it causes the subsequent blocking component to disengage from the mating pulley, releasing the lock. When it moves downward, it causes the blocking component to contact the mating pulley, locking the lock. An externally fixed blocking wheel 46 is fixedly connected to the sliding post 45. This fixed connection allows the blocking wheel 46 to move synchronously with the sliding post 45. The blocking wheel 46 is the core component for high-level locking. When it contacts the mating pulley, friction restricts the pulley's rotation, thus fixing the position of the slider 41. When it disengages, the pulley can rotate freely, and the slider 41... 1. The height can be adjusted. The external rotating connection of the blocking wheel 46 is connected to the outside of the slider 41. The rotating connection allows the blocking wheel 46 to flexibly adjust its angle when it moves with the sliding post 45, ensuring that the blocking wheel 46 can make precise contact with the mating pulley. At the same time, the slider 41 provides a stable mounting base for the blocking wheel 46, preventing the blocking wheel 46 from failing to lock due to force deviation. The external sliding connection of the lever arm 44 is connected to the inside of the slider 41. The sliding connection provides guidance for the rotation of the lever arm 44, limits the rotation range of the lever arm 44, and ensures that the lever arm 44 can accurately drive the sliding post 45 to move. This prevents the sliding post 45 from failing to drive the blocking wheel 46 to move reliably due to the deviation of the lever arm 44, ensuring the continuity of locking and unlocking.

[0054] Specifically, the sliding post 45 can slide inside the lever arm 44 and move up and down with the rotation of the lever arm 44. It is the execution carrier of the locking action. When it moves upward, it will drive the subsequent blocking component to disengage from the mating pulley to release the lock. When it moves downward, it will drive the blocking component to contact the mating pulley to lock. The blocking wheel 46 moves synchronously with the sliding post 45 and is the core component of height locking. When it contacts the mating pulley, it restricts the rotation of the pulley through friction, thereby fixing the position of the slider 41. When it disengages, the pulley can rotate freely so that the slider 41 can adjust its height. It can also flexibly adjust its angle with the movement of the sliding post 45 to ensure precise contact with the mating pulley. The slider 41 also provides a stable installation base for it to avoid locking failure due to force deviation. The lever arm 44 slides inside the slider 41. Its sliding connection can guide the rotation of the lever arm 44 and limit the rotation range, ensuring that the lever arm 44 accurately drives the sliding post 45 to move. It avoids the sliding post 45 being unable to drive the blocking wheel 46 to move reliably due to the deviation of the lever arm 44, and ensures the continuity of locking and unlocking.

[0055] A sliding wheel 47 is rotatably connected to the outside of the slider 41. This rotatable connection allows the sliding wheel 47 to rotate freely outside the slider 41. The outside of the sliding wheel 47 slides in contact with the inside of the supporting slide column 2. When the slider 41 adjusts its height, the sliding wheel 47 rolls along the supporting slide column 2, reducing friction between the slider 41 and the supporting slide column 2, making height adjustment smoother. Simultaneously, it engages with the blocking wheel 46 to achieve height locking. The external sliding connection of the sliding wheel 47 to the inside of the supporting slide column 2 ensures that the slider 41 can move stably up and down along the supporting slide column 2. A rolling track is provided for the sliding wheel 47 to limit the movement trajectory of the slider 41 and prevent the slider 41 from deviating. At the same time, the sliding wheel 47 and the blocking wheel 46 lock together to fix the adjusted height of the slider 41. The front end of the slider 41 is rotatably connected to the release agent spraying arm 48. The rotatable connection allows the release agent spraying arm 48 to adjust the spraying angle around the slider 41. The release agent spraying arm 48 is the execution part for spraying the release agent. Its height is adjusted with the slider 41 and its angle can be flexibly rotated to ensure that the release agent can be accurately sprayed on the surface of tires of different sizes and to ensure the tire demolding effect.

[0056] Specifically, the sliding wheel 47 can rotate flexibly outside the slider 41. When it cooperates with the support slide column 2, it can reduce the friction when the slider 41 is adjusted in height, making the adjustment smoother. At the same time, it can cooperate with the blocking wheel 46 to achieve height locking and ensure that the slider 41 moves stably along the support slide column 2 to avoid deviation. The release agent spraying arm 48 can adjust the spraying angle around the slider 41. Its height changes with the slider 41. As the execution part for spraying the release agent, it can ensure that the release agent is accurately sprayed on the surface of tires of different sizes, ensuring the tire demolding effect.

[0057] The implementation principle of this application embodiment is as follows: When the user needs to replace the top mold 382 at the start of use, the cylinder 7 simply pushes down the quick-change mechanism 3 and pulls the actuating column 32 outward. The actuating column 32 will move the locking block 33 together, and the locking block 33 will move the connecting column 34 out of the slot column 381, and move the sliding column 35 while squeezing the spring 37. The sliding column 35 will move the limiting ring 36 to slide inside the push plate 31. At this time, the cylinder 7 retracts the processing component 38 slightly, and it will fall off smoothly. When a new top mold 382 needs to be replaced, it is only necessary to repeat the process. Pulling the actuating column 32 outward and pushing the cylinder 7 downward slightly will insert the top mold 382. When the top mold 382 is inserted, release the actuating column 32, and the spring 37 will rebound and push the locking block 33 outward. The locking block 33 will drive the connecting column 34 to insert into the slot column 381, and also drive the sliding column 35 and the limiting ring 36 to slide outward together. The limiting ring 36 is to prevent the locking block 33 from being pushed outward excessively by the spring 37. At this time, the connecting column 34 and the opposite column will engage together to strengthen the connection, achieve quick connection, reduce the time for changing the top mold 382, ​​and enable the production of products of various sizes.

[0058] When the height of the release agent nozzle needs to be adjusted, squeeze the push block 42 downwards. The push block 42 will cause the power arm 44 to rotate downwards and make a lever motion. The other end of the power arm 44 will drive the sliding column 45 to slide upwards along the vertical slide reserved by the slider 41. The sliding column 45 will drive the blocking wheel 46 to move upwards and disengage from the sliding wheel 47. At this time, the push block 42 will squeeze the second spring 43, which will allow the release agent height adjustment mechanism 4 to slide up or down. When released, the second spring 43 will rebound and push the push block 42 upwards. The push block 42 will cause the power arm 44 to rotate upwards. The other end of the power arm 44 will drive the sliding column 45 to move downwards. The sliding column 45 will then drive the blocking wheel 46 to move downwards, so that the blocking wheel 46 and the sliding wheel 47 come into contact. The two sliding wheels 47 rotate in opposite directions and transmit forces in different directions. In this way, the sliding wheels 47 will restrain each other and cannot move, making it convenient to adjust the height.
