The two irregular cylinders match two symmetric long holes in a cavity respectively. An included angle between the wall of the upper end of each long hole and the top surface of a middle die is less than or equal to 88 degrees and greater than or equal to 80 degrees. A middle rod is arranged between the irregular cylinders, one end of the middle rod matches a step hole of the pedestal, and the other end of the middle rod matches a round hole in the cavity. A liftout plate is arranged under the pedestal in a close-fitting manner and is connected with a cylinder disposed on a fixed die base plate. Through cooperation among a lower type assembly, the cavity and an upper type punch, a molded cavity needed by a magnetic core is formed. Magnetic powder is put to fill the molded cavity and is extruded and molded through stamping of the upper type punch, and then a molded magnetic core is conveniently pushed out by the cylinder disposed on the fixed die base plate. The RM type magnetic core die convent to operate is simple in structure and high in molding efficiency.
