[0002] Tires are indispensable components of vehicles such as cars, trucks, and mining vehicles, and the performance of these vehicles is closely related to the characteristics of the tires.

[0003] Vulcanization is the process of chemical cross-linking of rubber macromolecules under certain conditions, where the certain conditions refer to time, temperature and pressure, which are usually referred to as the three elements of vulcanization. The stability of temperature during tire vulcanization is an important control point to ensure the accelerated cross-linking reaction of the tire. During the vulcanization process, water vapor is generated inside the closed vulcanizer steamer. Driven by heat, the water vapor rises to the highest position of the vulcanizer steamer and gathers. Due to the gap between the chuck on the capsule and the steamer on the vulcanizer, the gathered water vapor condenses in the gap to form condensed water that accumulates in the upper chuck and cannot be discharged, resulting in a decrease in the temperature of the tire sidewall, resulting in a lack of sulfur, which causes the tire to fail to cross-link normally and has poor wear resistance.

[0004] Based on this, the existing technology needs to be further developed. Utility Model Content

[0023] It should be noted that the water outlet of the first drain pipe 21 is fixedly connected to the upper pot body 11, so that when the vulcanizer opens and closes the mold, the first drain pipe 21 moves synchronously with the upper pot body 11. When the mold is closed, the first drain pipe 21 moves downward with the upper pot body 11, and the first drain pipe 21 and the second drain pipe 22 are connected through the docking of the male head 231 and the female head 232. At this time, the water inlet end of the first drain pipe 21 abuts against the capsule upper chuck 13 of the vulcanizer bladder 12. As the vulcanization work proceeds, the temperature in the vulcanizer steamer 1 gradually increases, and a pressure difference is formed between the inside and outside of the vulcanizer steamer 1. When condensed water accumulates in the capsule upper chuck 13, the condensed water is automatically discharged through the first drain pipe 21 and the second drain pipe 22 under the action of the pressure difference, so as to ensure the temperature stability during the tire vulcanization process and improve the wear resistance of the tire.

[0024] Specifically, the first drain pipe 21 extends out through the inspection port on the upper pot body 11 of the vulcanizer, and the water outlet of the second drain pipe 22 is located at a height lower than the water inlet of the first drain pipe 21, forming a siphon drainage, so that automatic drainage can be achieved even in the absence of steam pressure.

[0025] In the drainage device for a steamer-type vulcanizer of the present embodiment, the male head 231 includes a first connecting pipe 2311, a first end of the first connecting pipe 2311 is provided with an internal thread, a second end thereof is provided with a first ring body, a middle portion of the first ring body is provided with a protrusion 2312, a water outlet end of the first drainage pipe 21 is provided with an external thread, and the first drainage pipe 21 is threadedly connected to the first connecting pipe 2311; the female head 232 includes a second connecting pipe 2321, a first end of the second connecting pipe 2321 is provided with an internal thread, a second end thereof is provided with a second ring body, a groove 2322 matching the protrusion 2312 is provided on the second ring body, a water inlet end of the second drainage pipe 22 is provided with an external thread, and the second drainage pipe 22 is threadedly connected to the second connecting pipe 2321.

[0026] It should be noted that the cooperation between the protrusion 2312 and the groove 2322 improves the airtightness of the connection between the male head 231 and the female head 232. Furthermore, the side wall of the groove 2322 is inclined, and the inclined side wall has a guiding effect on the protrusion 2312, so that the male head 231 and the female head 232 can be docked more smoothly when the vulcanizer is closed.

[0027] In the drainage device for a steamer type vulcanizer of this embodiment, the first connecting pipe 2311 is integrally formed with the first ring body, and the second connecting pipe 2321 is integrally formed with the second ring body to ensure the accuracy of the connecting mechanism 23.

[0028] In the drainage device for a steamer type vulcanizer of this embodiment, a first annular groove for accommodating a sealing ring 2323 is provided at the joint between the first ring body and the second ring body. The sealing ring 2323 further improves the airtightness of the connection between the male head 231 and the female head 232.

[0029] Preferably, a pressure cover 2324 for limiting the sealing ring 2323 in the first annular groove is further provided at the joint between the first ring body and the second ring body to prevent the sealing ring 2323 from falling out of the annular groove and improve the stability of the sealing ring 2323.

[0035] Preferably, the valve 25 is configured as a high temperature resistant electromagnetic steam trap, and the frequency and duration of condensate discharge can be manually set to ensure that no condensate accumulates in the steamer and maintain a constant temperature.

[0036] When the vulcanizer is in mold closing, the first drain pipe 21 moves downward with the upper pot body 11, and the first drain pipe 21 is connected with the second drain pipe 22 through the docking of the male head 231 and the female head 232. At this time, the female head 232 is compressed, the spring 2325 is compressed, and the second connecting pipe 2321 moves along the fixed sleeve 26. The water inlet end of the first drain pipe 21 abuts against the capsule upper chuck 13 of the vulcanizer bladder 12. Under the steam pressure in the vulcanizer steamer 1 or under the siphon effect, the condensed water on the capsule upper chuck 13 is automatically discharged. When the vulcanizer is in mold opening, the first drain pipe 21 moves upward with the upper pot body 11, and the first drain pipe 21 is disconnected from the second drain pipe 22. The water inlet end of the first drain pipe 21 leaves the capsule upper chuck. At this time, the steam pressure and the siphon effect disappear, and the female head 232 is reset under the action of the spring 2325.

[0037] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
