塑料模材料失效原因分析
Failure Analysis of Plastic Mould Material
一般模具制造中包括模具设计、选用材料、热处理、机械加工、调试与安装等过程。根据调查表明:模具失效的因素中,模具所使用的材料与热处理是影响使用寿命的主要因素。从全面质量管理的角度出发,不能把影响模具使用寿命的诸因素作为多项式之和来衡量,而应该是多因素的乘积,这样,模具材料与热处理的优劣在整个模具制造过程中就显得特别重要。
General die manufacturing includes die design, material selection, heat treatment, mechanical processing, debugging and installation. According to the investigation, the material and heat treatment used in the die are the main factors affecting the service life of the die. From the point of view of total quality management, the factors affecting the service life of die can not be measured as the sum of polynomials, but should be the product of multiple factors. Thus, the advantages and disadvantages of die materials and heat treatment are particularly important in the whole process of die manufacturing.
从模具失效的普遍现象分析,塑料模具在服役过程中,可产生磨损失效、局部性变形失效和断裂失效。塑料模具的重要失效形式可分为磨损失效、局部塑性变形失效和断裂失效。
According to the analysis of the common phenomena of die failure, wear failure, local deformation failure and fracture failure can occur during the service of plastic die. The important failure modes of plastic moulds can be divided into wear failure, local plastic deformation failure and fracture failure.
