Die Casting Numerical Simulation Integration and Rapid Modeling System for Over-flow Groove Based on NX
Block UI Styler block style editor was utilized to design the pre-processing wizard interface based on NX10.0 platform,and the development of post-processing defect display and overflow groove interface was completed.Using the secondary development tool,the program of NX mesh segmentation by slice method was written.The simu-lated flow field file was traversed to look up the enrolling defects,and the surface related API function of UFUN was adopted to complete the post-processing display of enrolling and porosity defects,achieving the numerical simulation system integration of die casting.The NX expression technique was applied to create a parametric model of overflow groove as well as corresponding expression.The overflow groove location was obtained by gravity center projection of defect,and the rapid modeling of overflow groove was realized.The application example of shell die casting indicates that the system simplifies the simulation steps,and improves the efficiency of product development,which is of practi-cal value.
