基于UG的复杂箱体泡塑模具开发

AbstractLost Foam Casting(LFC)has been applied successfully to production of automotivegear-box by a dozen of foundry in China.But foam-mold's design and manufacture ofcomplex gear-box is still a technical problem for many LFC foundries.How to developfoam-mold efficiently and effectively,which is bottle-neck to promote LFC'sapplication.Emphasis in this paper is that:base on UG platform,we explore feasible.repeatable,dependable resolution focused on whole foam mold development.Base on UG/Modeling,we summarize a set of operational method specialized in threedimensional modeling and mold design of complex gear-box;3D parameterized standardpart of steam-base is built on UG CAD platform by utilizing UG re-development tools:UG/Open API,MenuScript,UIStyler,and Visual C++6.0,which improve the quality,efficiency,and standardization level of the aotumotive gear-box mold design and shorten itsdesign period;Base on our rich manipulated experience on UG,we summarize the category.origin and resolution of model quality,which we always meet in subsequent processe;Baseon UG/Manufacturing,we achieve effective and efficient manufacture of deep,narrow moldcavity and assemble foam-mold successfully.Specialized for complex gear-box foam mold,we form a mature technical routine.Two set of foam-mold we developed have been applied successfully in massproduction of 18686-C automotive case,which improve precision and lighten weight ofcasting,achieve more markets and customers for Shanxi Huaen Corporation.Key Words:UnigraphicsCADGear-Box Foam MoldLFCUG re-devlopmentModel QualityCNC
