Magnetic core forming mold and magnetic core production method

Abstract

The application belongs to the technical field of magnetic core manufacturing, and discloses a magnetic core forming die and a magnetic core production method. The magnetic core forming die comprises a female die, a floating die, a lower die, a core rod and an upper die. The female die, the floating die, the lower die and the core rod are sequentially sleeved and form an open cavity. The end of the core rod protrudes from the open cavity or is flush with the edge of the open cavity. The floating die, the lower die and the core rod form a first groove. The floating die is slidably connected with the groove and the core rod. The upper die is provided with a second groove. The upper die can be pressed into the open cavity to compact the magnetic powder in the open cavity and the first groove. When the upper die is pressed into the open cavity, the end of the core rod extends into the second groove, thereby realizing the effects of adjusting the density of the winding part and forming the weight-reducing holes on the winding part.
