Analysis and Optimization of the Structure Design of Tire Mold

本文以63.5#硫化机用于硫化12R22.5规格轮胎的活络模具为例,首先进行活络模具的结构设计,然后使用ANSYS有限元仿真软件,分析活络模具的热特性与力特性,根据生产要求设定优化目标,优化模具结构,最后分析结构优化前后的结果数据,验证模具优化效果,结构优化后模具的温模时间缩短了1.3 h,最大应力值减小了4.9 MPa,花纹块内轮廓的平均温度提高了1.8°C,温度均匀性与对称性均有所改善。

This paper takes 63.5#vulcanizer as an example,which is used to vulcanize 12 R22.5 tires.The main work is the structure design of tire mold.Use ANSYS finite element simulation software to analyze the temperature characteristics and stress of tire mold.Setting structure optimization target of tire mold according to production requirements.Analysis of data before and after tire structure optimization to verify the optimization effect.The results show that,after the structure optimization,the mold temperature time is shortened by 1.3 h,the maximum stress value is reduced by 4.9 MPa,the average temperature of the inner contour of the pattern block is increased by 1.8℃,and the temperature uniformity and symmetry are improved.
