Description

Technical Field

[0001] The utility model relates to the technical field of vulcanizers, in particular to a blowing sealing device for a steam chamber of a tire vulcanizer. Background Art

[0002] The steam chamber of the tire vulcanizer is a key equipment in the tire manufacturing process. It is responsible for vulcanizing rubber under high temperature and high pressure to solidify it into a part of the final product. During this process, the steam chamber must maintain a completely sealed state to ensure that the pressure and temperature of the steam can act evenly on the tire material, thereby ensuring the quality and efficiency of vulcanization. Therefore, the sealing performance of the steam chamber directly affects the safety of the vulcanization process and the consistency of the product.

[0003] In the traditional vulcanizer design, the steam chamber is usually sealed by sealing rings. These sealing rings are generally located at the interface between the upper steam chamber and the lower steam chamber. The upper and lower steam chambers need to be tightly pressed together by the clamping force to prevent steam leakage. However, this sealing method that relies on physical pressure has some problems. After long-term use, the clamping force may cause deformation of the steam chamber and fatigue damage of the sealing ring, which not only requires frequent replacement of the sealing ring, but may also affect the accuracy of the vulcanizer and the overall quality of the equipment.

[0008] Preferably, a through hole is provided in the middle of the annular V-shaped groove, and the presence of the through hole helps to maintain the pressure balance in the V-shaped groove and allows air or other media to pass through for operating the sealing ring or cleaning the inside of the groove.

[0009] Preferably, the sealing ring is an inverted V-shaped dovetail structure and is made of high-strength rubber, which is convenient for achieving the blowing and lifting effect. When the upper steam chamber is molded, the sealing ring elastically opens to provide effective sealing through its physical shape and material properties.

[0010] Preferably, the sealing ring forms an end face seal with the upper steam chamber when the mold is closed, forming a solid barrier between the steam chambers to prevent leakage of high-temperature steam and pressure.

[0011] Preferably, the inverted V-shaped dovetail structure of the sealing ring will elastically open after installation, so that the sealing ring can adapt to slight changes in the installation environment and produce a sealing effect on the device.

[0012] Preferably, a blowing hole is provided on the lower side of the sealing ring, and during use, a wind source with a certain pressure needs to be introduced into the blowing hole of the lower steam chamber, and compressed air is used to lift the sealing ring to enhance its sealing effect. By supplying air to the blowing hole, the position of the sealing ring can be quickly lifted, so as to better adapt to the pressure of the upper steam chamber and ensure that no leakage occurs during the vulcanization process.

[0013] Preferably, a bottom mounting plate is provided at the bottom end of the lower steam chamber, and the bottom mounting plate provides a stable mounting foundation for components such as the blowing holes.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The air blowing sealing device of the steam chamber of the tire vulcanizer uses an inverted V-shaped dovetail structure sealing ring. The device can automatically open and adapt to the contact surface during the mold closing process to provide a better sealing effect. In addition, the air introduced through the blowing hole further lifts the sealing ring, which not only strengthens the sealing effect, but also reduces the loss and deformation of the sealing ring caused by long-term use of the mold closing force, thereby reducing the maintenance frequency and cost;

[0016] 2. The steam chamber blowing seal device of the tire vulcanizer reduces the physical pressure of the mold clamping force on the seal ring and the steam chamber, thus avoiding equipment damage caused by excessive pressure, such as steam chamber deformation and seal ring fatigue. This design increases the overall durability of the equipment and improves the safety of operation because it reduces the risk of safety accidents that may be caused by equipment failure;

[0017] 3. The air blowing sealing device of the steam chamber of the tire vulcanizer reduces steam leakage through a more effective sealing mechanism, thereby maintaining the stability of the temperature and pressure in the steam chamber. This not only improves the quality and consistency of vulcanization, but also saves energy by reducing energy waste (such as additional heating and compression of steam). A faster sealing process also means a shorter vulcanization cycle, which improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The lower end of the upper steam chamber 1 is provided with the lower steam chamber 2, the clamping device 3 is connected between the upper steam chamber 1 and the lower steam chamber 2, the lower plane of the upper steam chamber 1 is provided with an annular V-shaped groove 4, and the lower end of the annular V-shaped groove 4 is provided with a sealing ring 6. In the steam chamber design of the tire vulcanizer, the upper steam chamber 1 and the lower steam chamber 2 are connected through the clamping device 3 to ensure that the two can be closely combined and form a sealed environment during the vulcanization process, the lower plane of the upper steam chamber 1 is provided with an annular V-shaped groove 4, and a sealing ring 6 is installed in the groove. This is a high-strength rubber product with an inverted V-shaped dovetail structure, which can be elastically opened when subjected to pressure to improve the sealing effect.

[0024] A through hole 5 is provided in the middle of the annular V-shaped groove 4. The sealing ring 6 is an inverted V-shaped dovetail structure and is made of high-strength rubber. The sealing ring 6 and the upper steam chamber 1 form an end face seal when the mold is closed. Before the vulcanization operation begins, the upper steam chamber 1 and the lower steam chamber 2 are tightly closed by the mold closing device 3. At this time, the sealing ring 6 is located in the annular V-shaped groove 4 and directly contacts the lower plane of the upper steam chamber 1 to form an end face seal. After the mold is closed, the inverted V-shaped structure of the sealing ring 6 automatically opens to adapt to the contact surface due to its material and design, thereby improving the sealing performance, in order to further enhance the sealing effect and reduce the physical pressure on the sealing ring 6.

[0025] After the sealing ring 6 is installed, the inverted V-shaped dovetail structure will elastically open. A blowing hole 7 is provided on the lower side of the sealing ring 6, and during use, a wind source with a certain pressure needs to be introduced into the blowing hole 7 of the lower steam chamber 2. A bottom mounting plate 8 is provided at the bottom end of the lower steam chamber 2. After the mold is closed, the inverted V-shaped structure of the sealing ring 6 automatically opens to adapt to the contact surface due to its material and design, thereby improving the sealing performance. In order to further enhance the sealing effect and reduce the physical pressure on the sealing ring 6, the design of the steam chamber includes a blowing hole 7 installed at the bottom of the lower steam chamber 2 through the bottom mounting plate 8. After the mold is closed, air with a certain pressure is introduced into the bottom of the sealing ring 6 through the blowing hole 7. The air pressure helps the sealing ring 6 to further open outward, thereby ensuring the sealing effect of the steam chamber and avoiding leakage of high-temperature steam.

[0026] Working principle: In the steam chamber design of the tire vulcanizer, the upper steam chamber 1 and the lower steam chamber 2 are connected by a clamping device 3 to ensure that the two can be tightly combined and form a sealed environment during the vulcanization process. The lower plane of the upper steam chamber 1 is equipped with an annular V-shaped groove 4, and a sealing ring 6 is installed in the groove. This is a high-strength rubber product with an inverted V-shaped dovetail structure, which can be elastically opened when under pressure to improve the sealing effect. Before the vulcanization operation begins, the upper steam chamber 1 and the lower steam chamber 2 are tightly clamped by the clamping device 3. At this time, the sealing ring 6 is located in the annular V-shaped groove 4 and directly contacts the lower plane of the upper steam chamber 1 to form an end face seal. After clamping, the sealing ring 6 Due to its material and design, the inverted V-shaped structure automatically opens to adapt to the contact surface and improves the sealing performance. In order to further enhance the sealing effect and reduce the physical pressure on the sealing ring 6, the design of the steam chamber includes a blowing hole 7 installed at the bottom of the lower steam chamber 2 through the bottom mounting plate 8. After the mold is closed, air with a certain pressure is introduced into the bottom of the sealing ring 6 through the blowing hole 7. The air pressure helps the sealing ring 6 to further open outward, ensuring the sealing effect of the steam chamber and avoiding leakage of high-temperature steam. This blowing sealing technology reduces the loss and deformation of the sealing ring caused by long-term use of the clamping force, extends the service life of the equipment, and maintains the operating efficiency and product quality of the vulcanizer.
