Description

Technical Field

[0001] This utility model relates to the field of molding die technology, specifically a tire vulcanization molding die. Background Technology

[0002] Tire vulcanization molding is a crucial step in the tire manufacturing process that determines product performance and quality. As the core equipment in this process, the mold's structural design and performance directly affect the molding accuracy of the tire tread pattern, production efficiency, and product consistency. During tire production, the mold needs to vulcanize the rubber material under high temperature and pressure to accurately replicate the preset tread pattern and other structures to meet the tire's functional requirements.

[0003] Currently, traditional tire vulcanization molding dies have some significant shortcomings in practical applications. The position adjustment of their movable tread blocks mostly relies on fixed structures or manual adjustments, making it difficult to flexibly adapt to the molding needs of tires of different specifications and tread designs. This often results in a single mold being usable only for specific tire models, leading to poor mold versatility and increased equipment investment costs for companies. In the demolding process, traditional molds lack effective auxiliary demolding structures. The friction between the tire and the mold is significant during demolding, increasing demolding difficulty, reducing production efficiency, and easily causing tire deformation and damage due to uneven or excessive force during demolding, thus affecting the finished product qualification rate. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a tire vulcanization molding die to solve the problems mentioned in the background art, such as the fact that the die can only be used for the production of specific tire models, has poor versatility, increases the equipment investment costs of enterprises, and is prone to deformation and damage of tires due to uneven or excessive force during demolding, thus affecting the finished product qualification rate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tire vulcanization molding die, comprising:

[0006] A lower mold is provided above the lower mold, and mold bases are installed on the surfaces of both the lower mold and the upper mold;

[0007] Mounting slots are provided inside the lower mold and the upper mold. A motor is installed inside each mounting slot. A guide rod is installed at the output end of each motor. A slider is installed on the surface of each guide rod. A mounting platform is installed on the surface of each slider. A movable patterned block is installed on the surface of each mounting platform.

[0008] A spring is provided on the back of both the lower and upper molds, and a release module is installed at the output end of the spring.

[0009] Preferably, guide blocks are installed on the surface of the mounting platform, and guide grooves are opened at the corresponding positions of the lower mold and the upper mold and the guide blocks. The guide blocks are inserted into the interior of the guide grooves, which can ensure that the mounting platform moves stably along the predetermined direction during the mold closing and opening process, avoiding deviation or shaking, thereby ensuring the accurate installation position of the movable pattern blocks and improving the quality and precision of tire vulcanization molding.

[0010] Preferably, both the guide block and the guide groove are T-shaped, and the protrusions of the guide block are embedded in the recesses of the inner wall of the guide groove. The T-shaped design structure makes the connection between the guide block and the guide groove more stable, and can withstand greater lateral forces, further enhancing the stability of the moving platform, preventing the guide block from coming out of the guide groove during mold operation, and ensuring the normal operation of the mold.

[0011] Preferably, mounting holes are provided on the surfaces of both the lower and upper molds at positions corresponding to the springs, and the springs are installed inside the mounting holes, making the spring installation more regular and ensuring that the demolding module can be evenly stressed under the action of the springs, thus achieving a stable and reliable demolding operation.

[0012] Preferably, each of the mounting platforms is equipped with a push plate, which is in close contact with the surface of the movable pattern block. The push plate increases the contact area with the movable pattern block. When it is necessary to replace or adjust the movable pattern block, the movable pattern block can be removed from or installed on the mounting platform more conveniently and smoothly by pushing the push plate, thereby improving the efficiency of mold maintenance and component replacement.

[0013] Preferably, limit rods are installed on the connecting side of the demolding module, and limit grooves are formed on the surface of the mold base at positions corresponding to the limit rods. The limit rods and limit grooves enable the demolding module to move vertically.

[0014] Compared with the prior art, the present invention provides a tire vulcanization molding die, which has the following beneficial effects:

[0015] The tire vulcanizing mold features a motor that drives a guide rod to move the slider, mounting platform, and movable tread blocks. This allows for flexible adjustment of the movable tread block's position to accommodate different tire tread patterns, enhancing the mold's versatility. The motor drive also ensures precise adjustment, contributing to consistent tire tread pattern formation. Springs on the back of the lower and upper molds drive the demolding action, utilizing the spring's elasticity to assist in demolding, reducing resistance during demolding, and minimizing the risk of tire damage due to excessive demolding force. This improves the quality of the finished tire and demolding efficiency. Attached Figure Description

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.

[0023] This utility model provides a technical solution: a tire vulcanization molding die. Please refer to [link / reference]. Figure 1 It includes a lower mold 1, an upper mold 2 is provided above the lower mold 1, and mold bases 3 are installed on the surfaces of both the lower mold 1 and the upper mold 2;

[0024] Please see Figure 3 Mounting slot 4 is located inside the lower mold 1 and the upper mold 2. Please refer to [link / reference]. Figure 2 Each mounting slot 4 contains a motor 5. Please refer to [link / reference]. Figure 4 Each output end of motor 5 is equipped with a guide rod 6, each guide rod 6 is equipped with a slider 7, each slider 7 is equipped with a mounting platform 8, and each mounting platform 8 is equipped with a movable patterned block 9.

[0025] Please see Figure 5 Spring 10 is set on the back of the lower mold 1 and the upper mold 2. The output end of spring 10 is equipped with a release module 11.

[0026] The mold base 3 mounted on the surfaces of the lower mold 1 and the upper mold 2 enhances the stability of the overall mold structure and improves the positioning accuracy during mold closing. The motor 5 in the mounting slot 4 drives the slider 7, mounting platform 8 and movable tread block 9 to move via the drive guide rod 6. The position of the movable tread block 9 can be flexibly adjusted to adapt to the molding requirements of different tire patterns, improving the versatility of the mold. The motor 5 drive ensures the precision of the adjustment process, which helps to ensure the consistency of tire pattern molding. The spring 10 on the back of the lower mold 1 and the upper mold 2 drives the demolding module 11 to move. The elastic force of the spring 10 can be used to assist in demolding, reducing resistance during demolding and reducing the risk of tire damage due to excessive demolding force. This is beneficial to improving the quality of finished tires and demolding efficiency.

[0027] Please see Figure 4 Guide blocks 12 are installed on the surface of the mounting platform 8. Please refer to [link / reference]. Figure 3 The lower mold 1 and the upper mold 2 are each provided with a guide groove 13 at the corresponding position of the guide block 12. The guide block 12 is inserted into the guide groove 13, which can ensure that the mounting platform 8 moves stably in the predetermined direction during the mold closing and opening process, avoiding deviation or shaking, thereby ensuring the accurate installation position of the movable pattern block 9 and improving the quality and precision of tire vulcanization molding.

[0028] Please see Figure 4 Both the guide block 12 and the guide groove 13 are T-shaped. The protrusions of the guide block 12 are embedded in the recesses of the inner wall of the guide groove 13. The T-shaped design structure makes the connection between the guide block 12 and the guide groove 13 more stable and can withstand greater lateral forces. This further enhances the stability of the movement of the mounting platform 8, prevents the guide block 12 from coming out of the guide groove 13 during mold operation, and ensures the normal operation of the mold.

[0029] Please see Figure 3 Mounting holes are provided on the surfaces of the lower mold 1 and the upper mold 2 at positions corresponding to the spring 10. The spring 10 is installed inside the mounting holes, making the installation of the spring 10 more regular and ensuring that the demolding module 11 can be evenly stressed under the action of the spring 10, so as to achieve a stable and reliable demolding operation.

[0030] Please see Figure 4 Each surface of the mounting table 8 is equipped with a push plate 14, which is in close contact with the surface of the movable pattern block 9. The push plate 14 increases the contact area with the movable pattern block 9. When it is necessary to replace or adjust the movable pattern block 9, the movable pattern block 9 can be removed from or installed on the mounting table 8 more conveniently and smoothly by pushing the push plate 14, thereby improving the efficiency of mold maintenance and component replacement.

[0031] Please see Figure 5Limiting rods 15 are installed on the connecting side of the ejector module 11. Limiting grooves 16 are opened on the surface of the mold base 3 at the corresponding positions of the limiting rods 15. The limiting rods 15 and the limiting grooves 16 enable the ejector module 11 to move vertically.

[0032] During operation: the lower mold 1 and the upper mold 2 are closed, and the mold seat 3 on its surface enhances the overall structural stability and improves the positioning accuracy; the motor 5 in the mounting groove 4 drives the guide rod 6, which in turn moves the slider 7, the mounting platform 8, and the movable tread block 9, adjusting the position of the movable tread block 9 to adapt to different tire tread molding requirements. At the same time, the guide block 12 on the mounting platform 8 is inserted into the guide groove 13 of the lower mold 1 and the upper mold 2. The T-shaped design of the two ensures the stable movement of the mounting platform 8 and guarantees the accurate installation position of the movable tread block 9. After vulcanization molding is completed, the spring 10 in the mounting hole on the back of the lower mold 1 and the upper mold 2 drives the demolding module 11 to move. The limiting rod 15 in the limiting groove 16 of the mold seat 3 makes the demolding module 11 move vertically. The elastic force of the spring 10 assists in demolding, and the push plate 14 increases the contact area with the movable tread block 9, which facilitates the replacement and adjustment of the movable tread block 9 and improves the efficiency of mold maintenance and component replacement.
