1、西華大學(xué)碩士學(xué)位論文射的四個重要工藝參數(shù)。其中,對雜物盒筋板根部凹陷深度影響最大的參數(shù)是熔體溫度和預(yù)注射量,對氣道最小壁厚影響最大的參數(shù)是熔體溫度和延遲時間,對產(chǎn)品最大翹曲量影響最大的參數(shù)是注氣壓力和熔體溫度。數(shù)值模擬獲得的雜物盒氣輔注射最優(yōu)工藝參數(shù)組合為:模具溫度35℃,熔體溫度2Q5℃,熔體預(yù)注射量100%,溢料井在7s時開啟和40s時關(guān)閉,注氣延遲時間7s,注氣壓力24MDa,冷卻時間60s。關(guān)鍵詞:雜物盒,氣輔注射,工藝參數(shù),產(chǎn)品質(zhì)量,正交實(shí)驗(yàn),數(shù)值模擬II西華大學(xué)碩士學(xué)位論文全mmericSinmlationandProcess0ptin血ationforGas越
