Abstract

Effects of lift velocity, structure size of lift tube on the flow morphology of mold filling were investigated by hydraulic simulation. It is found that a larger interior diameter (D₁) is beneficial to rapidly and smoothly filling mold with a given working section (S₄) of lift tube. S₁/S₂ (ratio of interior section and out-section) should be lower than 1.6, and S₄/S₂ ratio has the more significant effect on the flow morphology than the lift tube structure has when D₁ (interior diameter) is lower than 50 mm. S₁/S₂ should be lower than 3, and the lift tube structure has the more remarkable effect on the flow morphology when D₁ is more than 50 mm, so the proper conic ingate can be used to optimize the lift tube structure but S₄/S₂ should be lower than 25.
