The Fast Design and The Optimization of The injection Mold Based on CAD and CAE Technology

摘要

Using the reverse engineering software "Imageware", the kakou points cloud data were processed, the characteristic curve grids were divided and the curve surfaces were reconstructed in the paper. Then the reconstructed plastic model of the kakou was inputed in UG. With the help of the repair functions for UG software, the incontinuous curve surfaces were sew up, then the STL style of the kakou was saved. Using Mold Wizards of the UG, the assemble model of the mold was established, the parting surfaces were designed, the 3D models of the mold parts were acquired. With the help of Moldflow, the injection molding of the kakou was simulated and analyzed. According to the results of simulation, the structures of mold and the technology parameters were optimized .The mold design was changed digital, virtual and modern design from tradition design based on paper and experience.
