一、前言 压铸模设计中工艺参数和模具结构的合理性直接对压铸件的质量和成品率以及模具的使用寿命都会产生极大的影响。传统的模具设计主要依靠经验进行,使得压铸模具设计周期长,劳动强度大,稳定性差,且设计质量与设计者的经验有直接关系。这种落后状况造成了压铸模具设计和制造的不可靠性,使得大部分的压铸模具需要经过多次的反复试模、修模,增加了模具成本,延长了新产品的研制生产周期,制约着压铸工业的发展。 I. Preface Die casting mold design process parameters and the rationality of the mold structure directly on the die-casting quality and yield and the life of the mold will have a tremendous impact. The traditional mold design mainly relies on experience, which makes the design cycle of the die-casting mold long, labor-intensive, poor stability, and the design quality is directly related to the designer’s experience. This behind the situation caused the design and manufacture of die-casting mold unreliability, making most of the die-casting molds need to go through repeated trial and error mode, mold repair, an increase of mold costs, extending the new product development cycle, constraints Die-casting industry development.
