Abstract
Description
Technical Field
[0001] This application relates to the field of tire vulcanization technology, and in particular to a vulcanizing machine center mechanism for tire vulcanization. Background Technology
[0002] Tire vulcanization is a process in which rubber compounds with certain plasticity and viscosity are transformed into soft, elastic rubber products or hard, tough rubber products under specific external conditions through the action of chemical or physical factors, thereby obtaining their performance characteristics. Currently, tire vulcanization is generally carried out using vulcanizing machines.
[0003] In related technologies, the central mechanism of a vulcanizing machine comprises upper and lower side plates, upper and lower mold clamping plates, and a mold sleeve. The upper mold clamping plate includes an upper clamping plate and an upper cover plate, used to clamp the inner upper edge of the capsule. The lower mold clamping plate includes a lower clamping plate and a lower cover plate, used to clamp the inner lower edge of the capsule. The upper clamping plate and the upper side plate cooperate to form an upper patterned structure, and the lower clamping plate and the lower side plate cooperate to form a lower patterned structure, realizing the matching use of the upper and lower molds and the side plates.
[0004] However, when producing tires of different specifications, the traditional method requires replacing the upper and lower molds and side plates with matching ones; otherwise, tire rubber may flow between the clamping plate and the side plate, causing tire edge defects. This significantly reduces the versatility of the mold clamping plate and side plates, and increases resource consumption. Utility Model Content
[0005] To reduce resource waste, this utility model provides a central mechanism for a vulcanizing machine used in tire vulcanization.
[0006] The technical solution provided by this utility model for a central mechanism of a tire vulcanizing machine is as follows:
[0007] A central mechanism for a tire vulcanizing machine includes an upper side plate, an upper mold clamping plate, a lower side plate, and a lower mold clamping plate. Both the upper mold clamping plate and the lower mold clamping plate are used to clamp the tire bladder. The upper side plate has an upper tread pattern and a first groove, with the first groove located on one side of the upper tread pattern. The upper mold clamping plate is inserted into the first groove and connected to the upper side plate. The lower side plate has a lower tread pattern and a second groove, with the second groove located on one side of the lower tread pattern. The lower mold clamping plate is inserted into the second groove and connected to the lower side plate.
[0008] By adopting the above technical solution, the upper and lower mold clamps are respectively inserted into the grooves on the upper and lower side plates. This structural design allows the tire tread pattern to be stably formed on the side plates, reducing the problem of rubber edges forming during the vulcanization process of the bladder, thereby reducing the possibility of secondary tire processing due to rubber edges. Furthermore, this design allows one clamp to be adapted to multiple bladder sizes, significantly improving the clamp's versatility and utilization rate, while effectively reducing production costs. Since the mold clamps support quick interchangeability, bladders can be pre-installed in actual production. When abnormal situations such as bladder rupture or aging occur, a spare mold clamp can be immediately replaced without the need for time-consuming disassembly and reinstallation of the original clamp and bladder, thus greatly improving production efficiency.
[0009] Preferably, the shape of the first groove matches the outer contour of the upper mold clamping plate, and the shape of the second groove matches the outer contour of the lower mold clamping plate.
[0010] By adopting the above technical solution, the precise positioning and stable connection of the upper and lower mold clamping plates are improved, further enhancing the reliability of the overall structure and ensuring the uniformity and consistency of the vulcanization process. At the same time, it avoids the problem of rubber edges forming on the bladder during vulcanization, thus eliminating the need for secondary tire processing due to rubber edges.
[0011] Preferably, both the upper mold clamping plate and the lower mold clamping plate are provided with clamping structures for clamping the edge of the capsule. The clamping structure includes a clamping groove and a through hole. The through hole is used to connect the clamping groove with the outside. The capsule neck is located in the through hole, and the capsule edge is located in the clamping groove.
[0012] By adopting the above technical solution, the clamping structure effectively secures the capsule, ensuring its stable position during vulcanization and preventing tire quality issues caused by capsule displacement. The combined design of the clamping groove and through-hole not only facilitates capsule installation and removal but also accommodates capsules of different sizes, improving equipment compatibility and operational flexibility. Furthermore, this design simplifies the connection between the mold clamping plate and the capsule, reducing operational complexity and improving production efficiency.
[0013] Preferably, the top and bottom of the clamping groove are both serrated.
[0014] By adopting the above technical solution, the friction between the clamping groove and the capsule can be increased, thereby improving the stability of the capsule during the clamping process and reducing the possibility of displacement of the capsule during the vulcanization process.
[0015] Preferably, the upper mold clamping plate includes an upper clamping plate, an upper cover plate, and a first bolt. The upper cover plate covers the top of the upper clamping plate, and the first bolt passes through the upper cover plate and connects to the upper clamping plate to fix the upper cover plate and the upper clamping plate. The upper cover plate extends into the first groove and cooperates with the upper side plate.
[0016] By adopting the above technical solution, the connection stability between the upper mold clamping plate and the upper side plate can be enhanced, ensuring the precise positioning and sealing performance of the mold during the vulcanization process, thereby improving the quality of tire vulcanization.
[0017] Preferably, the lower mold clamping plate includes a lower clamping plate, a lower cover plate, and a second bolt. The lower cover plate covers the top of the lower clamping plate, and the second bolt passes through the lower clamping plate and connects to the lower cover plate to fix the lower clamping plate to the lower cover plate. The lower clamping plate extends into the second groove and cooperates with the lower side plate.
[0018] By adopting the above technical solution, the lower clamping plate and the lower cover plate are fixedly connected by the second bolt, and the lower clamping plate extends into the second groove to cooperate with the lower side plate, making the lower mold clamping plate more stable during installation and improving the overall structural stability. At the same time, this design facilitates disassembly and assembly, and is beneficial for maintenance and replacement of parts.
[0019] Preferably, both the upper clamping plate and the lower cover plate are provided with threaded holes, and the number of threaded holes is b; both the upper cover plate and the lower clamping plate are provided with fixing holes, and the number of fixing holes is a, where b is equal to a multiplied by 3, 4 or 5;
[0020] The first bolt passes through the fixing hole of the upper cover plate and is threadedly connected to the threaded hole of the upper clamping plate, and the second bolt passes through the fixing hole of the lower clamping plate and is threadedly connected to the threaded hole of the lower cover plate.
[0021] By adopting the above technical solution, when a bolt becomes disengaged, it can be quickly located and marked, and then rotated at a certain angle to continue use, effectively avoiding assembly interruptions caused by individual bolt problems. Simultaneously, tapping can be performed intensively while the chuck is idle, which not only improves operational flexibility but also significantly increases work efficiency and reduces maintenance costs.
[0022] In summary, this utility model has the following beneficial effects:
[0023] 1. The upper mold clamping plate and the lower mold clamping plate are respectively inserted into the grooves on the upper side plate and the lower side plate. This structural design allows the tire tread pattern to be stably formed on the side plate, reducing the problem of rubber edge formation during the vulcanization process of the bladder, thereby reducing the possibility of secondary tire processing due to rubber edge formation.
[0024] 2. This design allows a single clamping plate to accommodate capsules of various sizes, significantly improving the versatility and utilization of the clamping plate while effectively reducing production costs. Because the mold clamping plate supports rapid interchange, capsules can be pre-installed in actual production. In case of abnormalities such as capsule breakage or aging, a spare mold clamping plate can be immediately replaced without the need for time-consuming disassembly and reinstallation of the original clamping plate and capsules, thereby greatly improving production efficiency.

For example, multiple systems means two or more systems, and multiple screen terminals means two or more screen terminals. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the indicated technical features.

[0035] A central mechanism for a vulcanizing machine used for tire vulcanization, as described in reference Figure 1 and Figure 2 The system includes an upper side plate 1, an upper mold clamping plate, a lower side plate 5, and a lower mold clamping plate. The upper side plate 1 has an upper patterned structure 11 and a first groove 12, with the first groove 12 located on one side of the upper patterned structure 11. The upper mold clamping plate is inserted into the first groove 12 and connected to the upper side plate 1. The lower side plate 5 has a lower patterned structure 51 and a second groove 52, with the second groove 52 located on one side of the lower patterned structure 51. The lower mold clamping plate is inserted into the second groove 52 and connected to the lower side plate 5. The upper and lower mold clamping plates are used to clamp the edge of the capsule, thereby fixing the capsule.
[0036] This design, by separating the clamping plate and side plate, significantly improves the versatility of the mold and facilitates quick replacement for different tire specifications, thereby reducing resource consumption and improving production efficiency.
[0037] Reference Figure 2 The upper mold clamping plate includes an upper clamping plate 2, an upper cover plate 3, and a first bolt 4. The bottom of the upper cover plate 3 abuts against the bottom of the upper clamping plate 2. The first bolt 4 passes through the upper cover plate 3 and is threadedly connected to the upper clamping plate 2, thereby fixing the upper cover plate 3 to the upper clamping plate 2. A clamping structure 9 for clamping the edge of the capsule is formed between the upper cover plate 3 and the upper clamping plate 2.
[0038] Reference Figure 2 The shape of the first groove 12 matches the outer contour of the upper cover plate 3 in the upper mold clamping plate, and the upper cover plate 3 extends into the first groove 12 to cooperate with the upper side plate 1.
[0039] The upper mold clamping plate is inserted into the first groove 12 of the upper side plate 1, so that the tire tread structure can be stably formed on the side plate, reducing the problem of rubber edge generated during the vulcanization process of the bladder, thereby reducing the possibility of secondary processing of the tire due to rubber edge.
[0040] Reference Figure 2The lower mold clamping plate includes a lower clamping plate 6, a lower cover plate 7, and a second bolt 8. The bottom of the lower cover plate 7 abuts against the top of the lower clamping plate 6. The second bolt 8 passes through the lower clamping plate 6 and is threadedly connected to the lower cover plate 7, thus fixing the lower clamping plate 6 to the lower cover plate 7. A clamping structure 9 for holding the edge of the capsule is formed between the lower cover plate 7 and the lower clamping plate 6. The second bolt 8 adopts a countersunk hole design to prevent the second bolt 8 from protruding from the mold clamping plate, which would prevent the lower clamping plate 6 from fitting tightly with the lower side plate 5, causing step damage to the capsule and tire.
[0041] Reference Figure 2 The shape of the second groove 52 matches the outer contour of the lower clamping plate 6 in the lower mold clamping plate, and the lower clamping plate 6 extends into the second groove 52 to cooperate with the lower side plate 5.
[0042] The lower mold clamping plate is inserted into the second groove 52 on the lower side plate 5. This structural design allows the tire tread structure to be stably formed on the side plate, reducing the problem of rubber edge formation during the vulcanization process of the bladder, thereby reducing the possibility of secondary tire processing due to rubber edge formation.
[0043] Reference Figure 3 and Figure 4 Both the upper clamping plate 2 and the lower cover plate 7 have threaded holes, and the number of threaded holes is b; both the upper cover plate 3 and the lower clamping plate 6 have fixing holes, and the number of fixing holes is a, where b is equal to a multiplied by 3, 4 or 5.
[0044] For example, the quantity of 'a' is 6, and the quantity of 'b' is 18, 24, or 30. The specific values can be adjusted according to the actual usage scenario.
[0045] The first bolt 4 passes through the fixing hole of the upper cover plate 3 and is threaded into the threaded hole of the upper clamping plate 2. The second bolt 8 passes through the fixing hole of the lower clamping plate 6 and is threaded into the threaded hole of the lower cover plate 7.
[0046] When a bolt becomes dislodged, it can be quickly located and marked, and can be reused by rotating it at a certain angle, effectively avoiding assembly interruptions caused by individual bolt problems. Simultaneously, tapping can be performed intensively while the chuck is idle, which not only improves operational flexibility but also significantly increases work efficiency and reduces maintenance costs.
[0047] The first bolt 4 and the second bolt 8 are installed on the outside. When they become loose, they can be tightened in time to prevent the capsule from leaking air due to loose bolts, which would cause the internal pressure to drop and produce sulfided waste products, thus reducing the occurrence of waste products.
[0048] Reference Figure 5The clamping structure 9 includes a through hole 91 and a clamping groove 92. The clamping groove 92 is an annular groove and is formed on both the cover plate and the clamping plate. The through hole 91 is located on the outside of the clamping groove 92 and connects the clamping groove 92 to the outside. The capsule neck is located in the through hole 91, and the capsule edge is located in the clamping groove 92, thereby achieving capsule clamping.
[0049] The height of the through hole 91 allows for the installation and fixation of capsules of various sizes. When the edge of the capsule is clamped by the groove 92, the longitudinal height of the capsule decreases, and it expands in the horizontal direction.
[0050] Reference Figure 5 The top and bottom of the clamping groove 92 are serrated, which can increase the friction between the clamping groove 92 and the capsule, thereby improving the stability of the capsule during the clamping process and reducing the possibility of the capsule shifting during the vulcanization process.
[0051] The operating principle of this application is as follows: By inserting the upper mold clamping plate and the lower mold clamping plate into the first groove 12 of the upper side plate 1 and the second groove 52 of the lower side plate 5 respectively, a separate connection between the clamping plate and the side plate is achieved. This design not only improves the versatility of the mold but also simplifies the replacement process and reduces production costs. The precise design of the clamping groove 92 and the through hole 91 ensures a stable clamping of the capsule edge, effectively preventing rubber overflow and thus improving the quality of tire vulcanization. The number of mold clamping plates for dozens of capsule specifications is reduced to no more than three types, improving tooling utilization, reducing tooling inventory, saving clamping plate processing costs, reducing capital occupation, and alleviating tooling management costs.
[0052] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
