Abstract
The utility model discloses an EP type magnetic core die. A lower type punch has a U-shaped cross section, and the U-shaped part matches a long hole arranged in a cavity. The middle of the U-shaped part is provided with a middle rod one end of which matches a pedestal of the lower type punch, and the other end of the middle rod matches a round hole disposed in the cavity. The upper transverse plane of the round hole is lower than the top plane of a middle die. A liftout plate which is arranged under the pedestal in a close-fitting manner is connected with a cylinder disposed on a fixed die base plate. Through cooperation among cavities of the lower type punch, the middle rod and the middle die, a magnetic powder filling chamber is formed and a groove in an upper type punch is adopted to match the chamber, so a magnetic core is molded quite conveniently. Meanwhile, the cylinder arranged on the fixed die base plate enables the height of molding of the magnetic core to be adjusted flexibly. Moreover, it is convenient and fast to push out the molded magnetic core. The EP type magnetic core die convenient to operate is simple in structure and high in molding efficiency.
