Abstract
The utility model discloses a molding mould of soft magnet ferrite cores. The molding mould comprises an upper mould, a concave mould and a lower mould. The concave mould comprises a suspension table on the periphery of a mould body and a blank molding area in the center of the mould body. Material spraying grooves are arranged at edges of the blank molding area, and openings are arranged in the inner sides of the material spraying groove. According to the molding mould of soft magnet ferrite cores, the material spraying grooves are arranged at edges of the blank molding area, powder materials on the high-density portion in the molding process can be sprayed out through the material spraying grooves, accordingly, all portions of the produced products are even in density, poor buckling deformation generated due to density differences is avoided or reduced to the largest extent.
Description
Technical field
The utility model relates to a kind of mould, particularly relates to a kind of mould of magnetic ferrite magnetic core.
Background technology
Soft magnetic ferrite be kind at most, use the widest, the maximum a kind of magnetic material of consumption, be the important foundation functional material of electronic information and household electric appliances etc.Through the research and production of over half a century various countries' ferrite company, world's soft magnetic ferrite performance is greatly improved and improves, and its output increases progressively at a high speed year by year, and the scope of application also constantly enlarges.Soft magnetic ferrite magnetic core forming technology is to adopt the powder compacting technology at present, and the mould of traditional design is when moulding, and powder is a flat-die tool master mold face after filling; When patrix was depressed, powder moved inhomogeneous, and the moulding article can cause density contrast; Goods can produce shrinkage when sintering poor; Because each position shrinkage factor is different, the goods behind the sintering have buckling deformation, thereby influence quality of item even can not use.
Summary of the invention
To the deficiency of prior art, the purpose of the utility model is, a kind of mould structure is provided, and goods make each position density even when moulding, avoids or reduces the buckling deformation that produces owing to density contrast to greatest extent.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of mould of magnetic ferrite magnetic core; Comprise patrix, die and counterdie; The former blank molding district that said die comprises the hanging platform that is positioned at the die body periphery and is positioned at the die body center is characterized in that: the edge in said former blank molding district is provided with the spray hopper, and the inboard of said spray hopper is provided with opening.
The mould of aforesaid a kind of magnetic ferrite magnetic core is characterized in that: said spray hopper is arranged on the top of hanging platform.
The beneficial effect of the utility model is: the edge in former blank molding district is provided with the spray hopper; The powder at high density position can be through the ejection of spray hopper relatively in forming process; Thereby the goods of producing a position density is even, avoids or to reduce the buckling deformation that produces owing to density contrast to greatest extent bad.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
For further disclosing the technical scheme of the utility model; Now be described with reference to the accompanying drawings the embodiment of the utility model: as shown in Figure 1, a kind of mould of magnetic ferrite magnetic core comprises patrix 1, die 2 and counterdie 3; The former blank molding district 5 that die 2 comprises the hanging platform 4 that is positioned at the die body periphery and is positioned at the die body center; The edge in former blank molding district 5 is provided with spray hopper 6, and it is positioned at the top of hanging platform 4, and the inboard of this spray hopper 6 is provided with opening.Relatively the powder at high density position can be through 6 ejections of spray hopper in forming process, thereby the goods of producing a position density is even, avoid or to greatest extent minimizing owing to the buckling deformation that density contrast produces is bad.
More than, the basic design and the basic principle of the utility model have been set forth through introduction to listed embodiment.But the utility model never is limited to above-mentioned listed embodiment, and every equivalent variations, improvement of doing based on the technical scheme of the utility model reaches and deliberately become of inferior quality behavior, all should belong to the protection domain of the utility model.
Claims (2)
