长期以来,模具寿命始终是从事模具设计、制造、使用、研究等部门十分关注的问题。目前我国的模具使用寿命一般均未达到应有的水平,普遍偏低,直接影响了生产能力的提高和产品质量的稳定,增加了原材料的消耗,降低了经济效益,因而提高模具的使用寿命已成为当务之急。模具寿命的长短受到多方面因素的影响,主要有:产品零件结构设计及工艺性,模具结构设计,模具材料的选择,模具制造及装配精度,模具热处理及表面处理技术,模具的合理使用,压
For a long time, mold life is always engaged in mold design, manufacture, use, research and other departments are very concerned about the issue. At present, the service life of mold in our country generally do not reach the desired level, generally low, directly affect the improvement of production capacity and product quality, increase the consumption of raw materials and reduce economic benefits, thus increasing the service life of the mold has been Become a top priority. Mold life is affected by many factors, including: product structure design and technology, mold structure design, mold material selection, mold manufacturing and assembly accuracy, mold heat treatment and surface treatment technology, the rational use of mold, the pressure
