Novel automatic manganese-zinc soft magnetic ferrite core mold

Abstract

The novel automatic manganese-zinc soft magnetic ferrite core mold comprises a lower mold base, an upper mold base is arranged on the upper surface of the lower mold base, a shaping mold core is arranged in a mold opening of the lower mold base, and a limiting mechanism is fixedly connected to the lower surface of the inner wall of the lower mold base; the upper surface of the limiting mechanism is in lap joint with the lower surface of the shaping mold core; according to the device, the shaping mold core is arranged in the lower mold base, and the bottom of the shaping mold core is supported by the limiting mechanism, so that after raw materials are added, the vibration mechanism is driven by the air cylinder to ascend to be in soft contact with the shaping mold core, uniform and low-frequency stable vibration is carried out on the shaping mold core, the raw materials are uniformly distributed, and the raw materials are uniformly stressed during mold closing; and after the vibration mechanism descends and resets, the limiting rod is automatically reset through the spring and is inserted into the groove hole in the lower surface of the shaping mold core to limit the shaping mold core, through the design, the mold can ensure that raw materials are uniformly distributed when the raw materials are added, the stability of the mold is ensured when the mold is closed, and the quality of a magnetic core finished product is better.

Description

technical field [0001] The invention belongs to the technical field of molds, in particular to a new type of automatic manganese-zinc soft ferrite core mold. Background technique [0002] Magnetic core: Magnetic core refers to a sintered magnetic metal oxide composed of various iron oxide mixtures. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical magnetic core materials. Manganese-zinc ferrites are characterized by high magnetic permeability and high magnetic flux density with low loss characteristics. Nickel-zinc ferrite has the characteristics of extremely high resistivity and low magnetic permeability of less than a few hundred, and the mold industry is used for injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. Get a variety of molds and tools for the desired product. In a nutshell, a mold is a tool used to make a shaped item, this tool is made up of various parts, and different molds are ma...

Problems solved by technology

[0004] In order to overcome the deficiencies in the prior art, the present invention provides a new type of automatic manganese-zinc soft ferrite core mold, which avoids the fact that the existing mold is used in the actual use of the production of the magnetic core, due to the addition of raw materials to the mould, the raw material It is granular, and its accumulation in the inner cavity of the mold is not uniform enough, resulting in uneven force on the raw materials after the mold is closed, which makes the inside of the manufactured magnetic core not stable enough, which affects the quality of the magnetic core.
