Ferrite cores are used in coils and transformers of various electronic devices. In the mold industry, various molds and tools are used to obtain the required products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, the mold is a tool used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. The magnetic core mold refers to the mold used to produce the magnetic core.

[0003] In the prior art, the patent number is: CN216099941U discloses a positioning mechanism for a mold of an automobile plastic accessory, including a base, a limit block, a fixed rod and a limit assembly. A slide groove is provided in the middle of the inner part of the base, and movable grooves are provided on both sides of the upper end of the slide groove. A telescopic rod is provided at the bottom of the slide groove, and a disc is fixed on the upper end of the telescopic rod. Two groups of fixed blocks are fixed on both sides of the upper surface of the disc, and a fixed rod is hinged between each group of fixed blocks. The outer end of the fixed rod is clamped in the ball groove provided on the inner side wall of the movable groove, and a plurality of clamping grooves are provided on the upper surface of the rod body of the fixed rod at equal distances.
