[0026] Embodiment, as Figure 1 and Figure 2 shown, a capsule temperature measurement structure of a tire vulcanizing device includes a platinum thermal resistance 5 for detecting the temperature of the capsule and having a relatively long connection line. The platinum thermal resistance is connected to a transition flange 6. The transition flange 6 is thread - connected to the platinum thermal resistance 5. When the platinum thermal resistance 5 and the transition flange 6 are installed, by rotating the transition flange 6, the fastening effect of the platinum thermal resistance 5 can be achieved, avoiding damage to the cable or resistance caused by rotating the platinum thermal resistance 5.
[0027] The transition flange 6 is connected to the cylinder head. The cylinder head and the transition flange 6 are located inside the capsule. A placement hole 10 for the platinum thermal resistance 5 is provided at the corresponding position of the cylinder head. The cable of the platinum thermal resistance 5 extends out of the capsule through the placement hole 10, and the probe of the platinum thermal resistance 5 is located inside the capsule. In the form of the platinum thermal resistance 5 and the transition flange 6, when different specifications of platinum thermal resistances need to be replaced, different specifications of transition flanges can be replaced for adaptation, and the position of the flange connection hole does not need to change.
[0028] A groove 9 is machined on the cylinder head. The platinum thermal resistance 5 and the transition flange 6 are installed in the groove 9. By the setting of the groove 9, the height of the probe part of the platinum thermal resistance 5 inside the capsule is reduced, avoiding the influence of the capsule touching or squeezing on the measurement accuracy and even damaging the platinum thermal resistance. And the transition flange is arranged inside the capsule, which is convenient for installation.
[0029] The platinum thermal resistance is not higher than 30 mm from the end face of the cylinder head; more preferably, the platinum thermal resistance is not higher than the end face of the cylinder head, that is, the probe position of the platinum thermal resistance is completely placed inside the groove and not higher than the end face of the cylinder head.
[0030] A sealing ring groove is machined at the end face around the placement hole 10, and a sealing ring 8 is placed in the sealing ring groove. Through the installation and fastening of the transition flange, it is compressed to avoid gas leakage inside the capsule.
[0031] Figure 3 and Figure 4As shown, the transition flange 6 has a raised end, and the cylinder head is machined with a flange groove 11 at the platinum thermal resistance placement hole 10 to cooperate with the raised end of the transition flange.
[0032] A sealing groove 12 is provided on the side of the raised end of the transition flange 6 for installing a sealing structure, such as a sealing ring, to further enhance the sealing effect.
[0033] The raised end of the transition flange 6 cooperates with the side wall of the flange groove 11, and there is a certain interval between the raised end of the transition flange 6 and the bottom surface of the flange groove 11 to ensure the compression amount of the end face sealing ring, ensure the sealing effect, and at the same time reduce the processing precision requirements.
[0034] The capsule temperature measurement structure further includes a plug 7, and the plug 7 is provided with a thread adapted to the transition flange 6; a threaded hole can be opened near the platinum thermal resistance on the cylinder head, and the plug 7 is connected thereto as a backup; when there is no platinum thermal resistance for installation, after the transition flange and the central mechanism are fixed by screws before vulcanization, a temporary plug is used to block the central hole of the transition flange to ensure that the equipment can continue to produce.
[0035] The platinum thermal resistance can also be other temperature measurement elements, such as thermal resistance, thermocouple, etc., more specifically, copper thermal resistance, S-type thermocouple, etc.
