Abstract
Provided are a device and method for molding magnetic powder. The device includes a frame, a mold lifting mechanism, a plate pressing mechanism, a punch mechanism and a height locking mechanism. The mold lifting mechanism includes a mold and a first driving member for moving the mold up and down. The plate pressing mechanism includes a pressing plate and a second driving member for moving the pressing plate up and down. The punch mechanism includes a punch and a third driving member for moving the punch up and down. The height locking mechanism includes a first locking piece for locking the pressing plate and a second locking piece for locking the punch. The mold reciprocates upward and downward, such that a filling density of the magnetic powder is kept uniform, and the density distribution difference of the magnetic powder in a height direction is reduced.
