Description

[0002] A magnetic core is a sintered magnetic metal oxide composed of a mixture of various iron oxides. Among them, manganese-zinc ferrite and nickel-zinc ferrite are typical magnetic core materials. Magnetic cores are mainly used to store and transmit information, and are also used for signal amplification and filtering in communication equipment. Magnetic cores are also used in power supply systems. For example, in power systems, the magnetic core of a transformer is a very important component, which can effectively convert current and maintain the stability and safety of the system. In addition, magnetic cores are also widely used in power supply equipment such as inductors, inverters, and DC power supplies.

[0003] Compression molding is one of the key steps in the core manufacturing process. The commonly used process is wet pressing. In addition, the inductor core powder can be directly pressed after being mixed evenly, and then the inductor core is finally prepared after mold repair, sintering and spraying.

[0004] The shapes of magnetic cores are diverse, and different shapes of magnetic cores have their own advantages and disadvantages in applications. The selection of the appropriate magnetic core shape needs to be determined based on the specific application requirements.

[0113] S5: Component reset

[0114] After the molding is completed, the disc-shaped carrier 21 is lifted to a certain height by the cylinder 1 26, and the disc-shaped carrier 21 is rotated 180° and then stopped according to the steps in step S3, so that the conical molding block 234 on the conical molding assembly 23 is facing the inverted conical mold groove 121, so as to carry out the next pressing and molding of the conical inductor core filler.

[0115] The present embodiment provides a conical inductor core filler pressing and forming process, by dividing the inductor core filler into two parts with different masses, and adopting a two-step method to press and form the inductor core filler. During the pressing and forming process, filler A is first pressed to form a conical shell, and then filler B is filled into the conical shell to press and form a conical inductor core.
