濾清器殼體壓鑄製程設計及數值模擬

*翻譯來源《特種鑄造及有色合金》Vol. 39, Issue 7, Pages: 735-738(2019) Zhang Shuanglu 123 ,Mi Guofa 123 ,Wang Kai 123 ,Mao Changcheng 123 1School of Materials Science and Engineering,Henan Polytechnic University 2Henan Elite Science and Technology Co.,Ltd 3Henan Optics Electronic Co.,Ltd. 摘要：根據濾清器殼體的結構特點設計了壓鑄製程方案，採用FLOW-3D軟體對壓鑄製程方案進行數值模擬，通過捲氣分佈的情況預測產生缺陷的位置。初始方案模擬結果顯示，模穴內中間及兩端部位存在較多捲氣，容易產生氣孔等缺陷，通過溫度場分佈判斷壓鑄件凝固方式為逐層凝固，說明充型過程合理。優化方案調整了澆注系統的形狀和位置，增強了溢料井收集氣體的能力。結果顯示，鑄件內捲氣明顯下降，缺陷消除，滿足生產要求。關鍵字：壓
