The invention discloses a bidirectional pouring and sorting device for metal parts, and belongs to the technical field of the metal parts. The bidirectional pouring and sorting device for the metal parts comprises a base and a body frame. Two outer supporting frames and two inner supporting frames are arranged in the body frame. A control motor and a control box are arranged between the two inner supporting frames. A rotating shaft and two telescopic rods are arranged in the control box. The rotating shaft is provided with a rotary distribution plate, and the rotary distribution plate moves obliquely left and right under the action of the rotating shaft and the two telescopic rods. Connecting pieces are symmetrically arranged at the two sides of the body frame. The connecting pieces are provided with controllers. Control shafts are symmetrically arranged on the inner sides of the upper portions of the two outer supporting frames. The control shafts are provided with connecting shafts, and the connecting shafts are provided with rotating shafts. The rotating shafts are connected with guide plates. A plurality of buffer boards are arranged between the outer supporting frames and the inner supporting frames. A guide plate is arranged above the body frame. A rotary motor and a deflected discharging opening are arranged in the body frame. A distribution base plate is also arranged in the body frame. The bidirectional pouring and sorting device for the metal parts is reasonable in design, simple in structure and convenient to use. Different metal parts can be sorted, the buffer function can be achieved, automation is realized, and the device can be used conveniently.
