| Abstract: |
| The heat transfer of 9.00R20 and 12.00R20 inclined flat and Y985 conical segmented tire mold was simulated by ADINA software to study the effect of the change of the steam chamber of middle sleeve on the temperature distribution of the mold cavity.The upper end of the steam chamber of middle sleeve remained unchanged，and the bottom end moved upward，which reduced the volume of the steam chamber of middle sleeve and increased the strength of the lower end of middle sleeve.The average temperature of the mold cavity could be reduced by about 0.2 ℃ by reducing the volume of the steam chamber of middle sleeve，and the temperature distribution in the mold cavity under steady state was more uniform，which would be helpful to improve the vulcanization quality of tire，save energy,and reduce emission. |
