Reverse engineering modeling of motor hood and injection mold design

∗Firstly, the structure of the fan motor cover was analyzed, and the point cloud was obtained by scanning the plastic fan motor cover several times with a scanner and processed. Then, the geometric model was reconstructed. The design scheme of the gate position, gating system and cooling system of the mold was analyzed by using the software Moldflow, and the best design scheme was obtained. Finally, the overall structure of the mold is designed, and the appropriate mold frame is selected. The fan motor cover has many arc transition surfaces, which is difficult to measure, leading to the difficulty of modeling and mold design for the fan motor cover. The whole design process has certain guiding significance for the actual design of complex mold.
