Abstract: Development of injection mold for a back cover of CRT display was carried out based on CAE technology in this paper. The gates location were determined by gate location analysis and the optimum molding conditions was got by molding window analysis, then filling analysis was carried out to inspect the filling result, maximum injection pressure and clamp force, welt lines, and air trap locations. Finally, the mold was design based the result of CAE analysis and its structure and movement principle were illustrated.

Key words: CRT display, injection mold, computer aided engineering, back cover
