Study on Parametric Assembly Modeling of Standard Parts with Assembly Level of Mold Based on UG Secondary Development

Abstract

With the use of Visual C++ 6.0 programming development tools as the secondary development of Unigraphics NX (UG), dynamic link library DLL plug-ins were created. This paper takes fixed pedestal which is a standard part with assembly level of mold as an example, describing the parametric assembly modeling technology and implementation method of automatic virtual assembly process. The method can improve the design efficiency greatly by changing the related parameters of the parts to regenerate model fast and complete the design as well as assemble of fixed pedestal. It is proved that this method can meet the mould design requirements, and can be expanded and used for parameterized modeling and assembling of other standard parts with assembly level of mold in the practice.
