The slider 8 is closely fitted with the main body 1 of the device, and the sliding rod 9 is engaged with the limiting groove 7. The sliding rod 9 is symmetrically arranged with the central axis of the slider 8 as the center. After the ferrite core powder to be pressed is placed in the pressing groove 10 through the limiting groove 7, the slider 8 is moved along the limiting groove 7 by pulling the sliding rod 9, so as to flatten the surface of the ferrite core powder and avoid product quality defects due to uneven surface during pressing.

The telescopic rods 13 are evenly distributed around the central axis of the main body 1. Through the fixed frame 11, motor 12, telescopic rod 13 and return spring 14, after the ferrite core powder is pressed into shape, the motor 12 is started to drive the telescopic rod 13 to push upward and push out the pressed powder cake, realizing automatic material discharge without manual handling and improving work efficiency.
