Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a manganese-zinc ferrite core mold. Background Art

[0002] Ferrite core is a kind of high-frequency magnetic material (the principle is the same as silicon steel sheet, but it is used in high-frequency environment). It is mainly used for high-frequency transformers (such as switching power supplies, line output transformers, etc.), high-frequency magnetic rings (for anti-interference), etc., to increase magnetic permeability and improve inductance quality factors. It is used in transformers. When processing manganese-zinc ferrite cores, molds are required to press and form them. At present, the molds are mostly removed by the bottom punch of the stamping machine to eject the finished product. This has high restrictions on the use of the mold and is not suitable for most stamping machines. In addition, it is very inconvenient to disassemble and assemble the mold for different processing categories. For this reason, we propose a manganese-zinc ferrite core mold. Utility Model Content
