Problems solved by technology

[0002] At present, during the tire vulcanization process, steam heating is mostly used to heat the raw tire as a whole, and the temperature control of the tire mold is realized by adjusting the temperature and flow rate of the steam. However, there is a large lag in the adjustment of the steam heat source. If it is adjusted too early, it will cause under-vulcanization, and if it is adjusted too late, it will cause over-vulcanization, which is not conducive to improving the quality of tire vulcanization.
Moreover, the pattern block cannot cool itself, which also has a certain impact on the accuracy of vulcanization.
