"Die casting dies"是金屬加工領域的專業術語,指壓鑄工藝中用于成型金屬部件的精密模具。該術語包含三個核心要素:
壓鑄工藝(Die Casting)
通過将熔融金屬在高壓下注入模具型腔的制造技術,具有高效率、高精度的特點,廣泛應用于汽車和電子行業零部件的批量化生産。
模具核心功能(Dies)
包含定模(固定部分)與動模(移動部分)的成套工具,型腔表面精度可達Ra0.8微米,直接決定鑄件的尺寸精度與表面質量。典型模具壽命可達10萬至50萬次循環,具體取決于材料選擇與熱管理設計。
材料與制造要求
模具多采用H13熱作模具鋼(含Cr5%Mo1%V1%),經真空熱處理後硬度達到HRC46-50。現代制造結合五軸加工中心與放電加工(EDM)技術,可加工複雜冷卻水道系統。
該技術在新能源汽車領域的應用近年增長顯著,特斯拉一體壓鑄車身工藝使車體部件從70個減至2個,大幅提升生産效率。模具設計需同步考慮金屬流動仿真分析,以優化充型過程并減少氣孔缺陷。
“die casting dies”是一個工業制造領域的專業術語,其含義和用法如下:
