提高模具寿命方法的研讨

The Research on the Way to Enhance the Life-Span of Mould

本文首先从模具结构设计方面 ,分析了排样与搭边、模具导向结构、模具几何参数对模具寿命的影响 ;指出了合理选材并采用模具新材料对提高模具寿命的重要性 ;研究了 5CrMnMo钢制尾翅热锻模的高温淬火处理工艺与CrWMn钢制活动外桩冷冲凹模的低温淬火处理工艺 ,指出合理采用强韧处理工艺是提高模具寿命的又一条途径。最后列举了各种表面强化处理技术对模具寿命的影响。

The influence of the factors,such as arranging and ribband,orienting structure,geometric parameters,on the lifespan of mould,is discussed in this article in view of the structure design.And by Study of the high-temperature heat treatment of 5CrMnMo steel forging mould and the low-temperature quenching treatment of CrWMn steel pressing convex mould,some appropriate strong toughness disposal is proved a new way toward the improvement of the lifespan of the mould.At last,somexamples of the influence of the surface toughness disposal on the lifespan of the mould are given.
