Abstract: Development of injection mold for a wall speaker covers was carried out based on moldflow technology in this paper. The gates location were determined by gate location analysis and the balanced runner was got by runner balance analysis, then filling analysis was carried out to inspect the filling result of the two cavities, maximum injection pressure and clamp force. Finally, the mold was design based the result of moldflow analysis and its structure and movement principle were illuminated in details. Practice has proved that moldflow technology can be used to ensure the reasonable and efficiency of mold design and high quality products can be obtained quickly.

Key words: wall speaker covers, Moldflow, mold design, injection molding
