| Industry for aluminum alloy material quality of the products performance requirement is increasing day by day. Explore the vacuum casting of aluminum alloy is imminent. This paper studied under the condition of vacuum suction casting, with a specific structure characteristics of aluminum alloy test basic rule of the filling and solidification process of castings.Designed a kind of adjustable side suction vacuum suction casting mould, for the simulation analysis of this set of mould, draw the conclusion. Materials and side suction pads of different materials used in the whole mold, the mold cavity using cooling pads of different materials can adjust the cooling rate of the casting, the impact of the molten metal during solidification crystal crystalline order, quantity and crystal shape, grain refinement, happen eventually greatly improve the quality of castings, to avoid shrinkage porosity and other defects.Study on vacuum suction casting aluminum alloy and casting process simulation problem organizational control, the use of the continuity equation- mass conservation equation, NS equation- momentum conservation equation, joint finite element analysis software for process simulation, control study of the organizational structure of aluminum vacuum casting process A356 alloy was analyzed, considering the vacuum casting process parameters pouring temperature, suction mouth diameter, vacuum casting mold influence its structure, casting speed and other factors, the proposed vacuum casting A356 alloy casting process optimization in the general category parameter settings for later vacuum casting casting aluminum alloy castings such a scheme gives a certain reference. |
