塑料模具材料选择 Material Selection of Plastic Mould 1、塑料模的工作条件 1. Working Conditions of Plastic Moulds 由于塑料及塑料成型工业的发展,对塑料的模具的质量要求也越来越高,因而塑料模具的失效问题及其影响因素已成为重要的研究课题。塑料模的主要工作零件是成型零件,如凸模、凹模等,它们构成塑料模的型腔,以成型塑料制件的各种表面并直接与塑料接触,经受压力、温度、摩擦和腐蚀等作用。 With the development of plastics and plastic forming industry, the quality requirements of plastic moulds are getting higher and higher, so the failure of plastic moulds and its influencing factors have become an important research topic. The main working parts of plastic moulds are forming parts, such as punches, concave moulds, etc. They form the cavity of plastic moulds to form various surfaces of plastic moulds and directly contact with plastics. They are subjected to pressure, temperature, friction and corrosion. 2 、塑料模材料失效原因分析 2. 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 mater |
