A method for molding a flame-retardant bending beam integrated with a three-dimensional (3D) nylon air duct and a production mould thereof are provided. The method includes steps of: (1), producing the 3D nylon air duct; (2), selecting a flame-retardant carbon fiber pre-impregnated material: (3), laminating the pre-impregnated material and pre-molding; and (4), curing and molding composite material. The production mould includes an upper mould, a lower mould, sliding blocks and an air nozzle port. Compared with a traditional bending beam of metal molding, the flame-retardant bending beam integrated with the 3D nylon air duct achieves a same flame-retardant effect, and meanwhile has simple operation, flexible product shape, higher strength, lighter weight and corrosion resistance.
