摘　　要：为了解决两件式车轮铝合金轮辐镶嵌法铸造模具结构的设计,通过对常规重力模具结构及其合模开模顺序的分析,确定了轮辐模具的合模开模顺序,以及上模安放定位销、侧模开槽打孔和底部设计导正键的方案,解决了嵌件的准确固定问题。并使用铸件成形过程数值模拟软件ProCAST对铸件成形进行了分析,指出了铸件可能出现的缺陷部位和控制嵌件的工艺方法。从而确定了模具结构设计方案。The purpose is to solve the problem of designing casting mould structure with inserting method for AI alloy spoke of two-piece wheels. According to the analysis for the conventional gravity mold structure and the closing and opening order of mould, the technologies were determined, a proper closing and opening order of spoke mold, the dowel was fixed in the upper mold, the notch and stiletto in the side mole, the guide key was fixed on the bottom of the side-moulds, the question for fixing the inserts was solved correctly. An analysis has been made for casting forming by using the numerical simulation software ProCAST. In the analysis, processing methods for the defects locations which may appear in the castings have been pointed out as well as the one for inserts controlling. Theretbre, the solution for mould structure design has been determined.
