Based On Nx Die Mold Standard Parts Library Research And Development

Pressure casting is one of the most advanced metal forming methods, is to achieve no less margin processing and casting precision castings, thin wall, lightweight and energy-saving method of the important processes.With the rapid development of China’s automobile industry, the modern automobile lightweight, energy conservation, environmental protection, safer, more comfortable requirements, automobile parts used on the proportion of light alloy die-casting increasingly high, with continuous technical problems solution, the continual emergence of new equipment, die-casting will be a unique advantage in the manufacturing industry has been rapid development.With the die-casting mold design and manufacturing tasks increasingly heavy, promote the development of the die casting dies CAD technology. The establishment of standard parts library as an important foundation work of developed mechanical CAD software, is indispensable to practical the CAD system aspects.The topic analyses and researches the design principle and process of die-casting dies based on function, summarizes the design characteristics of the standard parts of die-casting dies. Research knowledge engineering (KBE) technology is applied to the development of the standard part library of die-casting dies. Research and summary design knowledge of matching, parameter driving, assembly for standard parts. In UG/NX5.0software platform, build the standard part library of die-casting dies based on knowledge engineering based on its providing second developing tools NXOpen,.net Framework2.0as a developing tool and c#as a programming language. Realize the processing of knowledge of the standard part of die-casting dies including the representation of knowledge, the reasoning of knowledge and the accessing of knowledge. Complete the intelligent selection, the intelligent generation and the intelligent positioning of the standard part.
