[0023] As Figure 3As shown, the cooling liquid inlet pipeline 70 is provided with a first valve element V1, and the cooling liquid outlet pipeline 80 is provided with a second valve element V2. When cooling is needed, the first valve element V1 and the second valve element V2 are respectively turned on, so that the cooling liquid can enter the capsule 12 through the cooling liquid inlet pipeline 70 and return to the cooling liquid source from the cooling liquid outlet pipeline 80. Preferably, the first valve element V1 and the second valve element V2 are on-off valves.

[0024] It should be noted that the cooling liquid inlet pipeline 70 is communicated with the capsule air inlet pipeline 30 near the capsule air inlet 121, so that the cooling liquid medium can quickly enter the capsule 12 to cool the capsule 12. As shown, Figure 2 As shown, the capsule air inlet pipeline 30 is provided with a third valve element V3 near the position connected with the cooling liquid inlet pipeline 70, and the third valve element V3 is arranged on the capsule air inlet pipeline 30 away from the cooling liquid inlet pipeline 70 and the capsule air inlet 121. When the cooling liquid medium is introduced into the capsule 12, the third valve element V3 is closed, so that the cooling liquid medium enters the capsule 12 through the cooling liquid inlet pipeline 70 and the part of the capsule air inlet pipeline communicated with the cooling liquid inlet pipeline 70, and does not enter the end of the capsule air inlet pipeline 30 away from the capsule air inlet 121 and the heating element C.

[0025] Further comprising a circulation air inlet pipeline 91 and a circulation air outlet pipeline 92, the medium circulation device 20 is communicated with the capsule air inlet pipeline 30 through the circulation air outlet pipeline 92, and the medium circulation device 20 is communicated with the capsule air outlet pipeline 40 through the circulation air inlet pipeline 91. Since the circulation air inlet pipeline 91 and the cooling liquid outlet pipeline 80 are respectively communicated with the capsule air outlet pipeline 40. When the cooling liquid medium is introduced into the capsule 12, the cooling liquid medium may enter the medium circulation device 20 through the capsule air outlet pipeline 40 and the circulation air inlet pipeline 91 in the process of entering the cooling liquid outlet pipeline 80 through the capsule air outlet pipeline 40. Therefore, in order to prevent the cooling liquid medium from entering the circulation air inlet pipeline 91, the circulation air inlet pipeline 91 is provided with a fourth valve element V4, and when the cooling liquid medium is introduced into the capsule 12, the fourth valve element V4 is closed, so that the cooling liquid medium does not enter the medium circulation device 20. Preferably, the fourth valve element V4 is a check valve, so as to prevent the cooling liquid medium from flowing back into the medium circulation device 20.

[0026] A seventh valve element V7 is provided on the circulating air outlet pipe 92 for opening the circulating air outlet pipe 92. An eighth valve element V8 is provided on the capsule air inlet pipe 30 for opening the capsule air inlet pipe 30; a ninth valve element V9 is provided on the capsule air outlet pipe 40 for opening the capsule air outlet pipe 40.

[0027] It should be noted that if the coolant enters the bladder 12 during the tire vulcanization process, it will affect the tire's vulcanization. Therefore, it is necessary to ensure that the coolant does not enter the bladder 12 during non-cooling phases. Figure 3 As shown, optionally, the cooling liquid inlet pipe 70 of this utility model is provided with a liquid flow detection element F, the liquid flow detection element F can be as follows: Figure 3 The liquid flow detection element F is positioned at the end of the cooling liquid inlet pipe that is furthest from the first valve element V1 and away from the capsule inlet pipe 30. Alternatively, the liquid flow detection element F can be positioned at the end of the cooling liquid inlet pipe that is closer to the capsule inlet pipe 30 and relative to the first valve element V1. The liquid flow detection element F is used to detect whether liquid is passing through. When the capsule 12 is not being cooled, i.e., the first valve element V1 is closed, if the liquid flow detection element F still detects liquid passing through, indicating a change in the flow rate at the liquid flow detection element F, it means that the first valve element V1 is malfunctioning and not functioning, and liquid is entering the capsule 12.

After the capsule 12 is cooled down by the cooling liquid medium, the main exhaust pipe 63 is used to discharge the cooling liquid medium in the vulcanization system to the cooling liquid source or a separate recovery device.
