Research of Design and Optimization for Injection Mold Based on CAD/CAE Technology

Changing the previous mold design methods based on experience, intuition or repeated testing molds, the design method with combination of the computer-aided design software UG, the data transfer software CADDoctor and the finite element analysis software MoldFlow is adopted for design and optimization for injection mold in the paper; the results showed that the mesh density may not be used as the standard basis for the accuracy analysis of plastic part by testing the indicators such as forming pressure, filling time and the maximum locked-mold force; through stimulation for filling analysis, cooling analysis and warpage analysis in the injecting procedure, the optimum design parameters for the feed system and cooling system of plastic part are obtained, and the distributing characteristics such as cavitation, weld lines and warpage are obtained to provide a significant reference for optimal design of mold structure; lastly, practice proved that the mold structure based on CAD technology can provide good flexibility, reliability and qualified products, and it can provide references for the colleagues. Application of CAD Technology in Injection Mold DesignThe plastic injection mold based on CAD technology can intuitively reflect the design thought of
