Abstract
The utility model discloses a die for manufacturing magnetic cores. The die comprises an upper die and a lower die. The upper die includes a first push segment and a first supporting segment both of which are cuboids. The first push segment and the first supporting segment have the same front, back, left and right symmetric planes. The side length of the first push segment is 0.08-0.3mm greater than that of the first supporting segment. The lower die includes a second push segment and a second supporting segment which are arranged in a coaxial manner. The second push segment is 0.08-0.3mm longer than the second supporting segment in diameter. Each of the upper die and the lower die is equipped with one push segment and one supporting segment, wherein the side length of the supporting segment of the upper die is smaller than that of the push segment of the upper die, and the diameter of the supporting segment of the lower die is smaller than that of the push segment of the lower die. When the upper die and the lower die are approaching each other, friction which only exists between the push segments and nearby auxiliary fixing parts is low and energy consumption during production is low. Matching areas between the upper and lower dies and the nearby auxiliary fixing parts are reduced, such that the centering precision between the upper die and the lower die is high to effectively minimize possibilities of geometric center displacement of magnetic cores and other quality problems.
