摘要
介绍了铝合金进气歧管倾转铸造工艺、浇注系统设计与模具设计,针对生产中容易产生的缩孔、缩松等铸造缺陷制定出合理的工艺方案。选择浇注时间为9.5s、内浇道截面积为1500mm2、模具温度为200～250℃、浇注温度为(710±10)℃。采用芯头部位抽气、厚大部位快冷及补缩等措施来解决铸造缺陷,提高了铸件品质。
Tilting casting,gating system and mould design of aluminum alloy air intake manifold were described. Aiming at shrinkage hole (porosity) defects which often exists in castings,processing sketch was rationally optimized. The aluminum alloy air intake manifold was manufactured successfully by tilted casting with ingate section of 1 500 mm2 and mould pre-heating at 200～250 ℃ and pouring at about 710 ℃ for 9.5 s,in which the shrinkage hole (porosity) was eliminated by adopting air-venting from core print and quickly cooling for the thick location as well as feeding,improving the casting quality.
