摘要
弓形座既是中套传递给花纹块硫化温度的载体,也是与花纹块精确配合实现花纹块径向运动的重要部件。根据轮胎结构及橡胶传热特性,有效地进行模具结构设计,使模具硫化温度建立在合理的硫化温度分布区块。通过对不同弓形座结构的计算机热传导模拟、分析花纹块胎肩处的硫化温度可知:增加弓形座腰带处尺寸,可使胎肩处硫化温度差减小至0.3~0.4,有利于该处橡胶硫化的同质性。
The slider is not only the carrier that the cone ring transmits to the vulcanization temperature of the block, but also the important part which realizes the radial precisely movement of the block. According to the tire structure and heat transfer characteristics of the rubber, effective mould structure is designed, and mould curing temperature is estab- lished in a reasonable temperature distribution. Through the computer simulation of heat conduction of the different slider structure, the vulcanization temperature at the shoulder of the block is analyzed. By increasing the size of the belt, the vulcanization temperature differencc of the shoulder can be reduced to 0.3-0.4℃ It is conducive to the vulcanization of rubber homogeneity.
