Description

Technical Field

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

[0002] In the tire manufacturing process, vulcanization is a crucial step. Vulcanization causes rubber molecules to form a cross-linked structure, which significantly improves the tensile strength, tear strength, and wear resistance of the tire. Vulcanized tires also have better elasticity and hardness.

[0003] During the vulcanization process of tires, the tire blank is first placed in the lower mold, and the bladder inside the lower mold is positioned inside the tire opening to prepare for subsequent inflation and expansion. Nitrogen gas is then injected into the bladder, which gradually expands until it fits tightly against the inner wall of the tire. A pneumatic cylinder is used to move the upper mold downward until the lower mold is in contact with the lower mold, completing the mold closing operation. The heating system continuously heats the rubber material, causing a chemical reaction under the action of temperature and pressure, gradually solidifying it into a tire with elasticity and wear resistance. The vulcanization reaction is a key step in tire molding, as it causes cross-linking between rubber molecules, thereby giving the tire excellent physical and mechanical properties.

[0004] Existing tire vulcanizing devices often leave tires with high temperatures after vulcanization. These high-temperature tires pose a risk of burns to operators during handling and processing. Furthermore, when the tires are clamped or moved by other means, the rubber material is soft and prone to deformation due to the high temperature, which affects the tire's quality and performance. Therefore, a tire vulcanizing device is proposed to address these issues. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background, this utility model proposes a tire vulcanization device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A tire vulcanizing device of this utility model includes a support base, a lower mold mounted on the support base, a capsule mounted at the center of the top side of the lower mold, four support rods fixedly connected to the top side of the support base, and an annular tube fixedly connected to the top of the four support rods. Multiple air outlets are provided on the annular tube. A cooler is mounted on the bottom side of the support base, and two air pipe channels are connected between the cooler and the annular tube. The diameter of the annular tube is larger than the diameter of the lower mold, and the diameter of the lower mold is the same as the diameter of the upper mold. After the tire vulcanization process is completed... After completion, a cooling fan operates, directing cold air through the air duct into the annular pipe. Finally, the air is sprayed onto the tire surface through the outlet. This direct application of cold air to the tire surface quickly removes heat, achieving rapid cooling. The annular pipe design ensures even distribution of the cold air across the tire surface, preventing uneven cooling and maintaining the overall stability of the tire's performance. This also prevents tire deformation during subsequent handling, ensuring tire production quality. Furthermore, it significantly reduces the risk of burns to operators when handling and processing tires, improving work safety.

[0007] Preferably, the bottom of the lower mold has two arc-shaped grooves, and the lower mold and the support base have two rod grooves that communicate with each other. Each arc-shaped groove contains a lifting block, and a U-shaped connecting frame connects the two lifting blocks. The two sides of the U-shaped connecting frame are respectively located within the rod grooves. The bottom of the support base has two fixed plates, each with a sliding groove. Each sliding groove contains a movable block, which is fixed to the two side walls of the U-shaped connecting frame. A threaded rod is rotatably installed in each sliding groove, passing through the movable block. A motor is installed at the bottom of each fixed plate, and the output end of the motor is connected to one end of the threaded rod. After the tire cools down, the motor rotates the threaded rod, forcing the movable block to move the U-shaped connecting frame upwards. The U-shaped connecting frame pushes the lifting block upwards, and the lifting block pushes the tire upwards, quickly removing the tire from the lower mold. This significantly improves demolding efficiency and shortens the production cycle.

[0008] Preferably, a fixing frame is installed on the top side of the support base, and a pneumatic cylinder is installed on the top side of the fixing frame. The working end of the pneumatic cylinder is equipped with an upper mold. When the tire is vulcanized, the upper mold is moved down by the operation of the pneumatic cylinder to complete the mold closing operation. The heating system inside the upper mold continuously heats the rubber material, causing it to undergo a chemical reaction under the action of temperature and pressure, and gradually solidify into a tire with elasticity and wear resistance. The vulcanization reaction is a key step in tire molding. It causes the rubber molecules to form a cross-linked structure, thereby giving the tire excellent physical and mechanical properties.

[0009] Preferably, the fixing frame has limit grooves on both sides, and limit blocks are slidably assembled in both limit grooves. The two limit blocks are respectively fixed to the two side walls of the upper mold. When using the device, the upper mold can be moved up or down stably through the cooperation of the limit grooves and limit blocks.

[0010] The advantages of this utility model are:

[0011] 1. After the tire vulcanization process is completed, the cold air is fed into the annular pipe through the air pipe channel by the operation of the cold air blower, and finally sprayed onto the tire surface through the air outlet. The cold air is directly sprayed onto the tire surface, which can quickly remove the heat from the tire surface and achieve rapid cooling. Moreover, the design of the annular pipe allows the cold air to be evenly distributed on the tire surface, avoiding uneven cooling in some areas. This ensures the stability of the overall performance of the tire, prevents tire deformation when the tire is moved later, ensures the production quality of the tire, and greatly reduces the risk of burns to operators when handling and processing the tire, thus improving work safety.

[0012] 2. After the tire cools down, the electric motor causes the threaded rod to rotate, which forces the movable block to move the U-shaped connecting frame upward. The U-shaped connecting frame pushes the lifting block upward, and the lifting block pushes the tire upward, quickly separating the tire from the lower mold. This significantly improves demolding efficiency and shortens the production cycle. Attached Figure Description

[0022] Please see Figure 1-5 As shown, a tire vulcanizing device includes a support base 1, a lower mold 2 mounted on the support base 1, a capsule 3 mounted at the center of the top side of the lower mold 2, four support rods 4 fixedly connected to the top side of the support base 1, and an annular tube 5 fixedly connected to the top of the four support rods 4. The annular tube 5 has multiple air outlets 6. A cooler 7 is mounted on the bottom side of the support base 1, and two air pipe channels 8 connect the cooler 7 to the annular tube 5. The diameter of the annular tube 5 is larger than the diameter of the lower mold 2, and the diameter of the lower mold 2 is the same as the diameter of the upper mold 20. Two arc-shaped grooves 9 are formed at the bottom of the lower mold 2, and two rod grooves 10 are formed between the lower mold 2 and the support base 1, with the rod grooves 10 corresponding to the arc-shaped grooves. 9 are connected; during operation, after the tire vulcanization process is completed, the cold air is operated by the cold air fan 7, which allows cold air to flow into the annular pipe 5 through the air pipe channel 8, and finally sprayed onto the tire surface through the air outlet 6. The cold air is directly sprayed onto the tire surface, which can quickly remove the heat from the tire surface and achieve rapid cooling. Moreover, the design of the annular pipe 5 allows the cold air to be evenly distributed on the tire surface, avoiding uneven local cooling, thereby ensuring the stability of the overall tire performance, preventing tire deformation when moving the tire later, ensuring the tire production quality, and greatly reducing the risk of burns to operators when handling and processing tires, thus improving work safety.

[0023] Please see Figure 2 and Figure 4-6As shown, each of the two arc-shaped grooves 9 is equipped with a lifting block 11, and a U-shaped connecting frame 12 is connected between the two lifting blocks 11. The two sides of the U-shaped connecting frame 12 are respectively set in the rod groove 10. Two fixing plates 13 are fixed to the bottom side of the support base 1. Each of the two fixing plates 13 is provided with a sliding groove 14. Each of the two sliding grooves 14 is equipped with a movable block 15, and the two movable blocks 15 are respectively fixed to the two side walls of the U-shaped connecting frame 12. A threaded rod 16 is rotatably installed in the two sliding grooves 14, and the threaded rod 16 passes through the movable block 10. 5. The bottom ends of the two fixed plates 13 are each equipped with a motor 17, and the output end of the motor 17 is connected to one end of the threaded rod 16. During operation, after the tire cools down, the motor 17 rotates the threaded rod 16, forcing the movable block 15 to move upward in the slide groove 14. The movable block 15 drives the U-shaped connecting frame 12 to move upward, the U-shaped connecting frame 12 pushes the lifting block 11 to move upward, and the lifting block 11 pushes the tire upward, quickly separating the tire from the lower mold 2, which significantly improves the demolding efficiency and shortens the production cycle.

[0024] Please see Figure 1-2 As shown, a fixed frame 18 is installed on the top side of the support base 1, and a pneumatic cylinder 19 is installed on the top side of the fixed frame 18. The working end of the pneumatic cylinder 19 is equipped with an upper mold 20. Limiting grooves 21 are opened on both sides of the fixed frame 18. Limiting blocks 22 are slidably installed in both limiting grooves 21, and the two limiting blocks 22 are respectively fixed to the two side walls of the upper mold 20. During operation, when the tire is vulcanized, the tire blank is first placed in the lower mold 2, and the capsule 3 is located in the tire opening. Then, nitrogen is filled into the capsule 3. As nitrogen is filled, the capsule 3 gradually expands until it is tightly attached to the inner wall of the tire. The upper mold 20 is moved down by the operation of the pneumatic cylinder 19 to complete the mold closing operation. The heating system in the upper mold 20 is continuously heated, so that the rubber material undergoes a chemical reaction under the action of temperature and pressure, and gradually solidifies into a tire with elasticity and wear resistance. Vulcanization reaction is a key step in tire molding. It makes the rubber molecules form a cross-linked structure, thereby giving the tire excellent physical and mechanical properties.

[0025] Working Principle: Existing tire vulcanization devices often leave tires with high temperatures after vulcanization. These high-temperature tires pose a risk of burns to operators during handling and processing. Furthermore, when the tire is clamped or moved by other means, the rubber material, being at a high temperature, is relatively soft and prone to deformation, affecting tire quality and performance. Therefore, a tire vulcanization device is proposed to address these issues. During the vulcanization process, the tire blank is first placed in the lower mold 2, with the bladder 3 positioned inside the tire opening. Nitrogen gas is then injected into the bladder 3, causing it to gradually expand until it tightly adheres to the tire's inner wall. The upper mold 20 is then lowered via a pneumatic cylinder 19, completing the mold closing operation. The heating system within the upper mold 20 continuously heats the rubber material, causing a chemical reaction under temperature and pressure, gradually solidifying it into an elastic and wear-resistant tire. Vulcanization is a crucial step in tire forming, creating a cross-linked structure between rubber molecules, thus endowing the tire with excellent physical and mechanical properties.

[0026] After the tire vulcanization process is completed, the upper mold 20 is moved to its initial state by the operation of the pneumatic cylinder 19. The cooler 7 (model AC360-20A) then directs cold air through the air pipe channel 8 into the annular pipe 5, and finally sprays it onto the tire surface through the air outlet 6. This direct spray of cold air rapidly removes heat from the tire surface, achieving rapid cooling. Furthermore, the design of the annular pipe 5 ensures that the cold air is evenly distributed across the tire surface, preventing uneven cooling and thus guaranteeing the overall stability of the tire's performance. The subsequent movement of the tire causes tire deformation, ensuring tire production quality. At the same time, the risk of burns to operators when handling and processing the tire is greatly reduced, improving work safety. After the tire cools down, the motor 17 operates, causing the threaded rod 16 to rotate, forcing the movable block 15 to move upward in the slide groove 14. The movable block 15 drives the U-shaped connecting frame 12 to move upward, the U-shaped connecting frame 12 pushes the lifting block 11 to move upward, and the lifting block 11 pushes the tire upward, quickly separating the tire from the lower mold 2, significantly improving demolding efficiency and shortening the production cycle.
