低壓鑄造升液管的制作方法技術(shù)領(lǐng)域：本實(shí)用新型涉及壓鑄機(jī)領(lǐng)域，特別是涉及一種低壓鑄造升液管。背景技術(shù)：低壓鑄造是使液體金屬在較低壓力作用下充填型腔、以形成鑄件的一種方法，其工藝過程是在密封的容器中，通入干燥的壓縮空氣，在氣體壓力的作用下，液體金屬沿升液管上升，通過澆口平穩(wěn)地進(jìn)入型腔，并保持坩堝內(nèi)液面上的氣體壓力；到鑄件完全凝固后，解除液面上的氣體壓力，使升液管中未凝固的液體金屬回流坩堝，再取出鑄件。由于低壓鑄造中的液體金屬充型比較平穩(wěn)，鑄件成形性好，輪廓清晰、表面光潔、致密，機(jī)械性能高，工藝收得率高，勞動(dòng)條件好，易于實(shí)現(xiàn)機(jī)械化和自動(dòng)化，因而低壓鑄造的方式得到使用。但升液管的幾何特性對(duì)液態(tài)金屬的流動(dòng)有很大影響，會(huì)直接影響到鑄件的冶金質(zhì)量，如鑄件內(nèi)的氣孔、氧化夾雜和夾渣都與升液管的性質(zhì)密切相關(guān)。已有的升液管存在的問題有1、在澆注的時(shí)候，液體金屬經(jīng)由升液管進(jìn)入型腔時(shí)，容易產(chǎn)生金屬噴濺，造成二次氧化夾雜、冷豆等鑄造缺點(diǎn)；2、當(dāng)液體金屬回流的時(shí)候，液體金屬流直接沖擊坩堝底部，會(huì)對(duì)坩堝底部的金屬形成沖擊攪動(dòng)，使沉淀坩堝底部的夾雜物重新懸浮起來，下次澆注時(shí)這些夾雜物隨液體金屬流進(jìn)入鑄件。奧翔硅碳傾城服務(wù)，確保產(chǎn)品質(zhì)量無后顧之憂。</p><div
