Pressing die for neodymium iron boron material

The utility model discloses a pressing die for a neodymium iron boron material. The pressing die for the neodymium iron boron material comprises an upper pressing core, a lower pressing core, cylindrical column cores and a die frame. The lower pressing core is placed inside the die frame, and half-round grooves are formed in the upper end surface of the lower pressing core. The upper pressing core comprises a convex pressing core body and a groove pressing core body, and the convex pressing core body and the groove pressing core body are successively matched with the lower pressing core for pressing raw material powder. The lower end surface of the convex pressing core body protrudes outwards for forming half-cylindrical structures, protrusions are embedded in the grooves of the lower pressing core, and therefore half-ring grooves are formed. Half-round grooves corresponding to the lower pressing core are formed in the lower end surface of the groove pressing core body, the column cores are arranged between the upper grooves and the lower grooves, and therefore annular grooves are formed. The pressing die for the neodymium iron boron material solves the problems that raw materials are wasted in a traditional neodymium iron boron ring pressing mode and the punching efficiency is low.
