Die CAD / CAE / CAM is developing in the direction of integration, three-dimensional, intelligence and network
(1) Function integration of mold software
The integration of mold software function in Guangdong mechanical processing plant requires that the software function modules are relatively complete, and each function module adopts the same data model to realize the comprehensive management and sharing of information, so as to support the whole process of mold design, manufacturing, assembly, inspection, testing and production management, and achieve the purpose of achieving the best benefits. For example, the series software of British Delcam company includes surface / solid geometric modeling, complex shape engineering drawing, advanced rendering of industrial design, plastic mold design expert system, complex shape cam, art modeling and engraving automatic programming system, reverse engineering system and complex shape on-line measurement system. The highly integrated software also includes Pro / Engineer, UG and CATIA. There are Shanghai Jiaotong University metal plastic forming finite element analysis system and blanking die CAD / CAM system in China; CAXA series software of Beijing Beihang Haier Software Co., Ltd; The stamping die CAD / CAE / CAM system of Jilin golden grid die engineering research center, etc.
(2) Three dimensional of mold design, analysis and manufacturing
The traditional two-dimensional die structure design of Guangdong machining plant has been more and more unable to meet the requirements of modern production and integrated technology. The three-dimensional and paperless die design, analysis and manufacturing require the new generation of Die software to design the die with a three-dimensional and intuitive feeling. The three-dimensional digital model can be easily used for CAE analysis of product structure, die manufacturability evaluation, NC machining, forming process simulation and information management and sharing. For example, Pro / Engineer, UG and CATIA software have the characteristics of parameterization, feature-based and full correlation, which makes die concurrent engineering possible. In addition, MoldEXPERT of cimatran, PS mold of Delcam and space-e / mold of Hitachi shipbuilding are 3D professional injection mold design software, which can carry out interactive 3D cavity, core design, mold base configuration and typical structure design. Moldflow advisors, a three-dimensional realistic flow simulation software of Moldflow company in Australia, has been widely praised and applied by users. There are similar software hsc3d4.5f developed by Huazhong University of technology and z-mold software of Zhengzhou University of technology in China. Manufacturing oriented and knowledge-based intelligent functions are important signs to measure the advanced and practical software of mold. For example, Cimatron's injection mold expert software can automatically generate parting line and parting surface according to the demoulding direction, generate core and cavity corresponding to the product, realize the full correlation of mold base parts, automatically generate material list and drilling table for NC processing, and set intelligent processing parameters and verify processing results.
3) Networking trend of mold software application
With the globalization and internationalization of mold in enterprise competition, cooperation, production and management, and the rapid development of computer software and hardware technology, the network makes it necessary and possible to apply virtual design and agile manufacturing technology in the mold industry. In its strategy for manufacturing enterprises in the 21st century, the United States points out that it is necessary to realize the agile production / virtual engineering scheme for the automobile industry by 2006, so as to shorten the automobile development cycle from 40 months to 4 months.
