【摘要】：針對低壓鑄造加工全封閉式組合電器鋁合金罐體產(chǎn)品合格率低的問題,通過ProCAST軟件對原鑄造工藝進(jìn)行模擬。通過對比試驗(yàn),并結(jié)合企業(yè)實(shí)際,確定優(yōu)化工藝參數(shù),并對鑄件形狀及澆注系統(tǒng)進(jìn)行改進(jìn),消除了鑄件缺陷。研究表明,澆注溫度為700℃、充型壓力為54kPa、模具預(yù)熱溫度為300℃時,對鑄件下半部外側(cè)壁厚增大1.5mm,形成適當(dāng)厚度梯度,并將原澆注系統(tǒng)內(nèi)澆道寬度增加7mm,可以消除鑄件缺陷,提高鑄件品質(zhì)。
[Abstract]:In order to solve the problem of low qualified rate of aluminum alloy tank in low pressure casting process, the original casting process was simulated by ProCAST software. Through contrast test, combined with enterprise practice, the optimization process parameters were determined. The casting shape and gating system were improved, and the defects of the casting were eliminated. The results show that when the pouring temperature is 700 鈩，
