Working principle: the mixed powder is placed in a charging box 13 and the apparatus is started. The powder flows out from the discharge pipe 131 and falls into the molding cavity 221 of the molding die 22 at the discharge level, and after the mass of the discharged powder reaches the prescribed requirement, the charging box 13 stops the outflow of the powder. The rotary table 21 rotates, the molding die 22 having the powder loaded therein rotates to a position corresponding to the compression transfer position, and the hydraulic cylinder 121 is pressed down to perform the compression molding process, whereby the powder is compressed into a magnet preform.
