[0032] Embodiment 2, which is mainly different from Embodiment 1 in that: a powder screening device for high-performance injection-molded samarium-cobalt magnets, a material discharge assembly 3 comprises a base plate 31 fixedly connected to the top of a support frame 2, an extension plate 32 fixedly connected to one side of the base plate 31, a vibration elastic pad 33 fixedly connected to the top of the base plate 31 and the extension plate 32, a synchronization plate 34 fixedly connected to the top of the vibration elastic pad 33, a vibration material frame 35 fixedly connected to one side of the synchronization plate 34, a stability frame 36 fixedly connected to one side of the stability frame 36, an eccentric wheel 38 fixedly connected to one end of the output shaft of the power motor 37, the top of the surface of the eccentric wheel 38 is tightly attached to one side of the bottom of the vibration material frame 35, and the eccentric wheel 38 rotates every time One circle can push the vibrating material frame 35 to vibrate once.
