模具的质量和寿命是相互关联的,影响模具寿命的主要因素有模具的材质和坯料处理、相关的热处理、模具的加工精度(轮廓精度和位置精度等)、模具的表面质量(包括表面粗糙度、硬度和表面层金相组织结构)等,其中最关键的影响因素是模具的精度,特别是模具的装配精度。要得到高精度的模具,其重要前提是零件精度高,本文重点讨论的 Mold quality and life are interrelated, the main factors affecting the life of the mold material and billet mold processing, related to heat treatment, mold machining accuracy (contour accuracy and position accuracy, etc.), mold surface quality (including surface roughness , Hardness and microstructure of the surface layer), etc., of which the most critical factor is the accuracy of the mold, especially the mold assembly accuracy. To get high-precision molds, the important premise is the high precision parts, this article focuses on the discussion
