圆锥面导向活络模具是硫化子午线轮胎的主要设备之一,其型腔的质量直接影响着子午线轮胎的外观质量。 硫化时出现问题主要是轮胎胶边及胎侧出现台阶现象。胶边分5种类型:1.花纹块接触面(立面)之间及上、下侧模花纹块配合处(周边)均出现胶边;2.只花纹块接触面(立面)之间出现胶边;3.上、下侧模与花纹块配合处(下、下周边)均有胶边;4.上侧模与花纹块配合处(上周边)出现胶边;5.下侧模与花纹块配合处(下周边)出现胶边。上述各种问题主要是由模具制造误差、装配不当等几方面原因造成的。
Conical surface-guided active mold is vulcanized radial tire one of the main equipment, the quality of its cavity directly affects the quality of radial tire appearance. Sulfide problems are mainly rubber tire side and sidewall phenomenon appears step. There are 5 types of glue edge: 1. There are rubber edges between the block contact surfaces (facade) and the upper and lower mold blocks (periphery); 2. Only between the block contact surfaces 3. The upper and lower mold and the block with the (lower and lower periphery) have a plastic edge; 4. The upper mold and the block with the Department With the block with the Department (the next week) appear plastic edge. The above problems are mainly caused by the mold manufacturing error, improper assembly and other reasons.
