摘　　要：电喷磁电机转子外壳凸包成型模具已于2011年2月注册为国家专利,专利号为ZL201020523519.5;该专利成功利用模具直接在飞轮壳体圆周上从内向外均匀或者不均匀单齿旋转冲多个凸齿(包),实现了多凸齿与壳体的冲压一体化制造,产品性价比高,同时也解决凸凹模强度差、寿命低、脱模、分度、变形等的技术难题。The design of convex hull molding die for EFI magneto rotor shell obtained China national prac- tical new-type patent in February 2011, and the number is ZL201020523519.5. The result shows that, several convex hulls can be punched successfully （homogeneous or non-homogeneous） from inside to out- side on flywheel housing by using convex hull molding die and realized the contemporary integration of the forming for convex hull and flywheel housing. The design of convex hull molding die has solved problems such as the poor strength, low life of concave-convex die, demolding and deformation, etc.
