Casting process in CAD, the use of three-dimensional drawinging software for solid modeling of parts and components to become the development trend, it will make cast production and computer closer together, completely free from casting process previously carried out by the human decision to tradition, the promotion of the production process CAD / CAE / CAM integration process. Particularly in the increasingly sophisticated CAD software today, how manufacturers and the actual needs of the secondary development of CAD software, it is from is vital.This article analyzes the casting process at home and abroad related to the development of CAD status and trends, combined with Valve of the actual production conditions and process design flow, using Pro/Engingeer 2002 as the secondary development platform, VC++6.0 as development language and environment, develop the casting process of pouring CAD systems and riser systems of Valve.This article is divided into three parts: a simple valve body design of gating system and riser systems design, and the use CAE software MAGMA to verify the accuracy of casting process . Gating system design is in its design and analysis module, computing, Sketch and four-part call, analysis is based on some of the major characteristics of castings to determine the shape of the casting surface, in order to facilitate placement in a suitable location casting system; calculation calculation of some of the major castings completely filling time, and the smallest runner and the runner cross-sectional area of the cross-sectional area ratio; Sketch some of the major position of the sprue, Sketch and size changes as well as the gate Cup Drawing.Riser system is designed for use mainly for library management, riser design and technology of drawing, database management riser part of the main parameters of the implementation of the use of visual user management, users can add, delete, and editor riser parameters, that is the key to riser design. At the same time, riser design and drawing process is based on the principle of casting solidification sequence, the use of hot pitch and riser module design method, according to MFC programming and the use of MFC dialog call DAO technology to the way dynamic link library to complete interface. Finally, CAE software, transferred to the design of a good 3D model castings, gating system and riser systems, the filling simulation of casting solidification process, and use relevant criteria to determine the use of CAD system design, the existence of the casting cavity, Shrinkage such as defects in the casting process to verify the gating system and riser CAD system accuracy.
