摘要
采用Abaqus软件对斜平面X1188轮胎活络模具(简称斜平面轮胎模具)中套汽室的硫化温度场进行了模拟分析。结果表明:斜平面轮胎模具单温中套汽室对应的型腔花纹块内表面上侧温度比下侧温度略高,最高温度出现在花纹块内表面中间;在保持单温中套汽室初始温度条件的基础上采用多温中套汽室时,花纹块内表面温差减小,温度分布更加均匀;对花纹块上下肩部进行倒角结构优化后,花纹块内表面温差进一步降低,温度场更加集中于花纹块内表面中间且分布更为均匀,同时花纹块使用的材料减少,从而可在保证轮胎硫化温度的条件下降低经济成本。
Abaqus software was used to simulate and analyze the vulcanization temperature field of middle sleeve steam chamber of the inclined plane X1188 tire segment mold(referred to as the inclined plane tire mold).The results showed that the upper temperature of pattern block inner surface of the single temperature middle sleeve steam chamber in the inclined plane tire mold was slightly higher than the down temperature,and the highest temperature appeared in the middle of the pattern block inner surface.When using multiple temperature middle sleeve steam chamber while maintaining the initial temperature conditions of single temperature middle sleeve steam chamber,the temperature difference of the inner surface of the pattern block decreased and the temperature distribution became more uniform.After optimizing the chamfering structure of the upper and lower shoulders of the pattern block,the temperature difference of the inner surface of the pattern block was further reduced,and the temperature field was more concentrated to distribute in the middle of the inner surface of the pattern block and more uniform.At the same time,the material used for the pattern block was reduced,which could reduce economic costs while ensuring tire vulcanization temperature.
