摘　　要：介绍了大型复杂铝合金箱体铸件采用水平分型的模具结构设计及铸造工艺的设计,侧重于直浇道正斜度浇注反斜度出型,冒口反斜度出型正斜度补缩的设计,以及通过在普通重力浇注机上增加反压装置的设计,实现了普通浇注机在无顶出油缸情况下完成铸件的出型和顶出。The structure design and casting process of the large permanent casting mold with the horizontal parting for large and complex Al-alloy housing castings were introduced, focus on the process design with the positive draft angle sprue and the mold open with negative angle, as well as the process design of the mold open with negative draft angle dead head and the feeding with positive angle, by equipping the ordinary gravity filler with counterpressure device to assure that the ordinary filler fulfills the open and ejection without hydrocylinder.
