Description

Technical Field

[0001] This invention relates to the field of rubber sealing ring production technology, specifically to a vulcanization treatment device suitable for use with rubber sealing rings. Background Technology

[0002] Vulcanization refers to the process by which a rubber layer is heated at high temperatures under the action of an accelerator, causing it to change from a linear molecular structure to a network molecular structure. A sealing ring is a common rubber product widely used in various mechanical equipment to prevent liquid or gas leakage. In the existing rubber sealing ring processing, the rubber strip to be vulcanized is laid on the lower heating mold, and then the upper and lower heating molds are closed to pressurize and heat the rubber. After vulcanization is completed, the upper and lower heating molds are separated, the vulcanized rubber sheet is removed, and another piece of rubber is moved between the upper and lower heating plates to prepare for vulcanization.

[0003] In the prior art, such as the flat vulcanizing machine disclosed in CN221717569U, which relates to the field of rubber processing and production technology, this utility model includes a base, a support column fixedly connected to one side of the top of the base, and a control machine body provided on the other side of the top of the base. A lifting mechanism is provided inside the support column, and a demolding mechanism is provided at the top of the lifting mechanism. By setting up the demolding mechanism, the rubber can be quickly demolded, improving the efficiency of the flat vulcanizing machine. The lifting mechanism facilitates better mold closing between the lower and upper mold bases, improving the overall performance of the flat vulcanizing machine.

[0004] The aforementioned document uses a demolding mechanism, which quickly ejects the vulcanized rubber from the lower mold base. However, during the demolding process, the vulcanized plate is subjected to prolonged impact on the bottom of the plate, causing deformation between the moving slot and the locking block, which in turn leads to blockage of the vulcanized plate's feeding and discharging.

[0005] Therefore, this invention proposes a vulcanization treatment device suitable for use with rubber sealing rings to solve the problem that existing vulcanized plates are prone to impact on the bottom of the plate during the demolding process by the demolding mechanism, causing deformation between the moving slot and the block, which in turn leads to the jamming of the vulcanized plate when it is fed or discharged. The device can provide sufficient support to the vulcanized plate while absorbing the impact force generated during the demolding process. Summary of the Invention

[0032] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1, please refer to Figures 1-12 This invention provides a technical solution: a vulcanization treatment device suitable for rubber sealing rings, including a vulcanizing machine body 1, an outer connecting plate 11 and a lower mold guide plate 12 connected to the outer side of the vulcanizing machine body 1, a lifting mold movably connected to the outer connecting plate 11, a lower mold movably connected to the inner side of the lower mold guide plate 12, a vulcanizing plate 3 movably installed on the upper end of the lower mold, V-shaped grooves opened on the inner walls of both sides of the vulcanizing plate 3, a support rod 13 fixedly connected between the outer connecting plate 11 and the lower mold guide plate 12, a pneumatic clamp 2 fixedly connected to the upper end of the support rod 13 by bolts, a reserved groove 20 opened on one end of the inner side of the pneumatic clamp 2, a vulcanizing plate suspension mechanism provided on the inner side of the reserved groove 20, the vulcanizing plate suspension mechanism including a pneumatic pushing component and a reverse clamping component, the pneumatic pushing component including an air storage cylinder 21 and a plate clamping strip 261, the reverse clamping component including a connecting arm 28 and a linkage component;

[0034] In this embodiment, through the design of the lower mold and the vulcanizing plate 3 overlapping, when the two are moved out synchronously, the vulcanizing plate suspension mechanism, in conjunction with the vulcanizing plate suspension mechanism, achieves rapid suspension of the vulcanizing plate 3 through pneumatic principle, retracts the lower mold, and uses the air pressure pushing component to push the plate clamping strip 261 to fit and engage with the V-groove on the side of the vulcanizing plate 3. At the same time, the reverse clamping component responds quickly and flexibly clamps the side of the vulcanizing plate 3. This device provides sufficient support force to the vulcanizing plate 3 while also absorbing the impact force generated during demolding, avoiding the problem of jamming when the vulcanizing plate is fed or discharged after long-term use, extending the overall service life of the device, and improving the production efficiency of vulcanized rubber sealing rings.

[0035] In Example 2, based on Example 1, in order to achieve pneumatic ejection and retraction of the flat plate clamping strip 261 and ensure that the flat plate clamping strip 261 is quickly limited when the vulcanizing plate 3 reaches the demolding position, an air storage cylinder 21 is fixedly installed on the inner surface of the pneumatic clamp 2. An air inlet pipe is provided at the input end of the air storage cylinder 21. A fixed plate 22 is fixedly installed in the inner cavity of the air storage cylinder 21. A movable plate 23 is movably connected to the end of the fixed plate 22 away from the air inlet pipe. A sealing soft plug 221 and a sealing groove 222 are fixedly installed on the fixed plate 22. A sealing groove 231 and a sealing soft plug 232 are fixedly installed on the movable plate 23. Both the sealing groove 222 and the sealing groove 231 are set as hollow tubular structures. The outer surface of the sealing soft plug 221 is adapted to engage with the inner surface of the sealing groove 231. The outer surface of the sealing groove 231 is adapted to engage with the inner surface of the sealing groove 222.

[0036] In this embodiment, as Figure 5 As shown, the air inlet pipe at the input end of the air storage cylinder 21 is designed to replenish the internal cavity of the air storage cylinder 21 with air. The air source is transmitted through the sealing groove 222 on the inner wall of the fixed plate 22. At this time, the air source pushes the sealing soft plug 232 through the sealing groove 222. Subsequently, the air source separates the fixed plate 22 and the movable plate 23 that were initially combined. The movable plate 23 moves to the side of the fixed plate 22 under the influence of the air source. At this time, the connecting spring 24 is stretched and deformed by the movement of the movable plate 23. The air source is transmitted to the movable plate 23 and the piston plate 23 through multiple sets of sealing grooves 231. The space between 6 is filled with air. With continuous pneumatic replenishment, the piston plate 26 pushes the flat plate clamping strip 261 to move towards the V-shaped grooves on both sides of the vulcanizing plate 3. In this way, the flat plate clamping strip 261 quickly limits the vulcanizing plate 3. It should be noted that the upper surface of the lower mold and the lower surface of the vulcanizing plate 3 are actively connected by the clamping groove and the clamping block. At this time, the lower mold is retracted to the top of the upper mold by driving the electric telescopic rod at one end of the lower mold. Thus, the bottom of the vulcanizing plate 3 is exposed, and then the vulcanized rubber sealing ring on the surface of the vulcanizing plate 3 is demolded by the top mold lifting upward.

[0037] In Example 3, based on Example 2, to avoid insufficient air supply to the inner cavity of the air storage cylinder 21 due to insufficient air source pressure, this example further proposes that a receiving groove is provided on the inner wall of the fixed plate 22 near the movable plate 23, and a connecting spring 24 is fixedly connected to the inner wall of the receiving groove. The other end of the connecting spring 24 is fixedly connected to the outer surface of the movable plate 23. Electromagnet one and electromagnet two are respectively provided on the inner surfaces of the fixed plate 22 and the movable plate 23. Electromagnet one and electromagnet two are electrically connected and set as two identical magnetic poles. A piston rod 25 is fixedly connected to one end of the movable plate 23 away from the fixed plate 22, and a piston plate 26 is fixedly connected to the other end of the piston rod 25. The outer ring surface of the piston plate 26 is slidably connected to the inner wall of the air storage cylinder 21. A sealing end plate 27 is movably embedded in the outer surface of the piston plate 26. The sealing end plate 27 is fixedly installed at the end of the air storage cylinder 21 away from the air intake pipe. A connecting rod is fixedly connected to the side of the piston plate 26 near the sealing end plate 27. The connecting rod is slidably connected to the central inner wall of the sealing end plate 27. The other end of the connecting rod is fixedly connected to the outer surface of the flat plate clamping strip 261.

[0038] In this embodiment, as Figures 5-6 As shown, if an unexpected situation occurs in the air intake pipe, the movable plate 23 will no longer be under the force of the air source. At this time, the connecting spring 24 will drive the movable plate 23 to pull back to the side of the fixed plate 22, so that the movable plate 23 will reset. At this time, the sealing groove 231 and the sealing soft plug 221, and the sealing soft plug 232 and the sealing groove 222 are mutually adapted, and the fixed plate 22 and the movable plate 23 are sealed. The connecting spring 24 can not only assist the reset of the movable plate 23, but also maintain the stability of the movable plate 23 during the movement and retraction process. It should also be noted that, in order to avoid insufficient air source pressure, the electromagnets 1 and 2 are simultaneously energized. Due to the principle of opposite magnetic poles repulsion, the movable plate 23 moves away from the fixed plate 22 again. Then, the clamping strip 261 on the side V-groove of the vulcanized plate 3 can be continuously maintained by the electromagnetic principle, avoiding the retraction of the clamping strip 261 due to insufficient pressure, and further ensuring the stable suspension of the vulcanized plate 3.

[0039] Embodiment 4. On the basis of Embodiment 3, in order to enable the flat clamping strip 261 to clamp the fibers in the V-shaped groove on the side of the vulcanizing flat plate 3 while联动实现硫化平板3两侧的柔性夹紧 (the flexible clamping on both sides of the vulcanizing flat plate 3 is realized in a linked manner), the connecting arms 28 are fixedly installed on both sides of the flat clamping strip 261. The other ends of the connecting arms 28 are fixedly connected with fixed toothed plates 281. The fixed toothed plates 281 are in a "C"-shaped plate structure. Driven gears 282 are meshed and rotated on both sides of the fixed toothed plates 281. A connecting rod 2821 is fixedly connected to the inner surface of the center of the driven gear 282. A knob 2822 is fixedly connected to the outer surface of the upper end of the connecting rod 2821. The outer surface of the connecting rod 2821 is rotationally connected to the inner wall of the pneumatic fixture 2; A sliding toothed plate 283 is meshed and rotated on the outer surface of the driven gear 282. The sliding toothed plate 283 is in an overall "C"-shaped plate structure arranged opposite to the fixed toothed plate 281; A limiting member is arranged outside the sliding toothed plate 283. A chute 2830 is opened on the outer side surface of the sliding toothed plate 283. The limiting member includes a convex plate 201. The convex plate 201 is fixedly installed on the inner surface of the reserved groove 20. The outer surface of the convex plate 201 is slidably connected to the inner surface of the chute 2830;

[0040] In this embodiment, as Figures 7-12 shown, reverse clamping assemblies are installed on both sides of the flat clamping strip 261. When the flat clamping strip 261 moves forward towards the side of the vulcanizing flat plate 3, the connecting arm 28 drives the fixed toothed plate 281 to move forward synchronously. At this time, both sides of the fixed toothed plate 281 are engaged with the driven gear 282, and the driven gear 282 rotates. Under the action of meshing transmission, the sliding toothed plate 283 makes a movement trajectory opposite to that of the fixed toothed plate 281. At this time, the sliding toothed plate 283 drives the swing clamping arm 291 connected to one side to retract inward; It should be noted that a chute 2830 is opened on the outer side of the sliding toothed plate 283, and it is slidably adapted to the surface of the convex plate 201. The two cooperate with each other to provide structural support for the sliding toothed plate 283 while ensuring the horizontal stable movement of the sliding toothed plate 283; And it should be noted that the knob 2822 extends to the upper part of the pneumatic fixture 2. When the driven gear 282 rotates, the knob 2822 rotates synchronously. When it is necessary to retract the sliding toothed plate 283, if the flat clamping strip 261 is no longer pushed by gas at this time, or the gas pressure is insufficient, the sliding toothed plate 283 can be reset by reversely screwing the knob 2822.

[0041] It should be noted that the part "联动实现硫化平板3两侧的柔性夹紧" in the original text seems to be an incomplete or incorrect expression. I have translated it as "the flexible clamping on both sides of the vulcanizing flat plate 3 is realized in a linked manner" for the sake of translation integrity, but it may need to be adjusted according to the correct content.In Example 5, based on Example 4, to achieve stable clamping of both sides of the vulcanizing plate 3 by the suspension clamping plate 292, this example further proposes that the linkage includes a fixed platform 29, which is fixedly installed on the outer surface of the sliding toothed plate 283. A swing clamping arm 291 is rotatably connected to the upper side of the fixed platform 29, and the other end of the swing clamping arm 291 is fixedly connected to the suspension clamping plate 292. A flexible bladder plate 2921 is fixedly connected to the lower surface of the suspension clamping plate 292. The two ends of the plate 2921 are movably connected to the limiting grooves 202, which are opened on the inner surface of the reserved groove 20; the swing clamp arm 291 has a curved plate-shaped structure, and a shaft 2911 is fixedly connected to the inner wall of the upper end of the swing clamp arm 291. A movable rod 2912 is rotatably connected to the outer surface of the center of the shaft 2911, and a shaft 2913 is rotatably connected to the other end of the movable rod 2912. The two ends of the shaft 2913 are fixedly connected to the inner wall of the reserved groove 20 respectively.

[0042] In this embodiment, as Figures 9-12 As shown, when the swing clamping arm 291 moves towards the fixed toothed plate 281 at one end connected to the fixed platform 29, the swing clamping arm 291 presses downward. With the setting of the limiting groove 202, the swing clamping arm 291 is limited. At this time, the angle of the movable rod 2912 changes, thereby driving the suspended clamping plate 292 to press downward synchronously. The flexible bladder plate 2921 can increase the flexibility of clamping with the side of the vulcanizing plate 3. When the bottom of the vulcanizing plate 3 is impacted by the top mold, the two sets of parallel clamping flexible bladder plates 2921 can absorb the impact force brought by the top mold, ensuring the stable demolding of the vulcanizing plate 3. At the same time, it can also reduce the damage to the pneumatic clamp 2 and the vulcanizing plate 3, extend the overall service life, and further improve the production efficiency of vulcanized rubber sealing rings.

[0043] In actual use, firstly, the vulcanizing plate 3 is installed on the lower mold. Then, strips of rubber are placed sequentially on the vulcanizing plate 3. The electric telescopic rod at one end of the lower mold is controlled to move the lower mold and the vulcanizing plate 3 together to a position directly below the lower mold. After the upper mold and the lower mold are pressed together, the strips of rubber form a mesh structure. After a period of time, the upper mold is raised, and the electric telescopic rod is activated again to push the lower mold and the vulcanizing plate 3 to one side of the lower mold guide plate 12. At this time, both sides of the vulcanizing plate 3 just enter the reserved groove 20 inside the pneumatic clamp 2 for limiting. The electric telescopic rod controls the lower mold to retract. At this time, the storage... One end of cylinder 21 has an air inlet pipe connected to an external air source, which replenishes the internal cavity of the air storage cylinder 21 with air. The air source transmits gas through the sealing groove 222 on the inner wall of the fixed plate 22. At this time, the air source pushes the sealing soft plug 232 through the sealing groove 222. Subsequently, the air source separates the fixed plate 22 and the movable plate 23, which were initially merged. The movable plate 23 moves to the side away from the fixed plate 22 due to the influence of the air source. At this time, the connecting spring 24 is stretched and deformed by the movement of the movable plate 23. The air source is transmitted to the movable plate 23 and the movable plate 23 through multiple sets of sealing grooves 231. The space between the piston plates 26 is filled with air. With continuous pneumatic supply, the piston plate 26 pushes the flat plate clamping strip 261 to move towards the V-shaped grooves on both sides of the vulcanizing plate 3, thus achieving rapid positioning of the vulcanizing plate 3 through the flat plate clamping strip 261. As the flat plate clamping strip 261 moves towards the side of the vulcanizing plate 3, the connecting arm 28 drives the fixed toothed plate 281 to move forward synchronously. At this time, the two sides of the fixed toothed plate 281 mesh with the driven gear 282. The driven gear 282 rotates, and under the action of meshing transmission, the sliding toothed plate 283 moves against the fixed toothed plate 282. The toothed plate 281 moves in the opposite direction. At this time, the sliding toothed plate 283 drives the swing clamping arm 291 connected on one side to retract inward. When the end of the swing clamping arm 291 connected to the fixed table 29 moves close to the fixed toothed plate 281, the swing clamping arm 291 presses downward. With the setting of the limiting inclined groove 202, the swing clamping arm 291 is limited. At this time, the angle of the moving rod 2912 changes, thereby driving the suspension clamping plate 292 to press downward synchronously. Finally, the top mold is driven to the bottom of the vulcanizing plate 3 for demolding, ensuring that the vulcanized rubber sealing ring is automatically demolded.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
