Description

Technical Field

[0002] Ferrite core is a high-frequency magnetic material, mainly used for high-frequency transformers, high-frequency magnetic rings, etc., to increase magnetic permeability and improve inductance quality factor. Since the annular ferrite core has no air gap and the cross-sectional area is consistent, the magnetic effect is very high. Powder molding technology is used in the production of ultra-thin soft ferrite cores. At present, most ultra-thin soft ferrite core molding molds include a plate with a groove on the surface. When in use, powder is put into the groove, and then a stamping tool is used to stamp it out. After the molding is completed, pliers and other tools are used to remove it. In the process of moving the plate containing powder to the lower end of the stamping device, since there is no protective cover on the upper end of the groove, the powder can easily fall off with the wind and float into the air, resulting in a decrease in the quality of the formed core.

[0003] Therefore, it is necessary to provide a new ultra-thin soft ferrite core forming die to solve the above technical problems. Utility Model Content

[0013] The utility model provides an ultra-thin soft ferrite core forming die, which, when implemented:

[0014] 1. When the device is in use, the motor drives the driving bevel gear to rotate, thereby driving the transmission bevel gear to rotate.
