"Die casting dies"是金属加工领域的专业术语,指压铸工艺中用于成型金属部件的精密模具。该术语包含三个核心要素:
压铸工艺(Die Casting)
通过将熔融金属在高压下注入模具型腔的制造技术,具有高效率、高精度的特点,广泛应用于汽车和电子行业零部件的批量化生产。
模具核心功能(Dies)
包含定模(固定部分)与动模(移动部分)的成套工具,型腔表面精度可达Ra0.8微米,直接决定铸件的尺寸精度与表面质量。典型模具寿命可达10万至50万次循环,具体取决于材料选择与热管理设计。
材料与制造要求
模具多采用H13热作模具钢(含Cr5%Mo1%V1%),经真空热处理后硬度达到HRC46-50。现代制造结合五轴加工中心与放电加工(EDM)技术,可加工复杂冷却水道系统。
该技术在新能源汽车领域的应用近年增长显著,特斯拉一体压铸车身工艺使车体部件从70个减至2个,大幅提升生产效率。模具设计需同步考虑金属流动仿真分析,以优化充型过程并减少气孔缺陷。
“die casting dies”是一个工业制造领域的专业术语,其含义和用法如下:
