Abstract
The utility model relates to a last two moulds once of ferrite core, including upper punch, well mould, outer down stroke, interior down stroke, its characterized in that upper punch sets up in well mould top to corresponding with the die cavity of well mould central authorities department, outer down stroke setting is in well mould below, and corresponding with the die cavity of well mould central authorities, and interior down stroke passes outer down stroke setting outside below the down stroke. Upper punch, well mould, outer down stroke, interior down stroke are coaxial. Be provided with the draught in the well mould die cavity. Well mould die cavity is " worker " font structure. The utility model discloses because the configuration mode who adopts outer down stroke, interior down stroke to combine together can effectively adjust the partial density of iron core center pillar, does benefit to ferrite core's one -step refining shaping, is favorable to the drawing of patterns of goods moreover. When being used for producing, only need to start the lathe with expecting the bad die cavity of putting into the mould, badly carry out the punching press through upper punch, outer down stroke, interior down stroke to expecting respectively, can accomplish the injection molding of part.
Description
Technical field
The utility model relates to mould applications, specifically once two molds in FERRITE CORE.
Background technology
Mould be in industrial production in order to injection moulding, blowing, extrude, various mould and instrument that the method such as die casting or forging forming, smelting, punching press, stretching obtains required product.In brief, mould is used to the instrument of formed article, and this instrument is made up of various part, and different moulds is made up of different parts.It realizes the processing of article profile mainly through the change of institute's moulding material physical state.Press the difference of shaping material, mould can be divided into metal die and nonmetal mould.Metal die is divided into again: casting mould (non-ferrous metal die casting, steel casting) and forging mold etc.
The processing technology classification of processing metal pressed by mould, and conventional has: stamping die, comprises blanking die, bending die, Drawing Die, flange die, reducing die, forcer, bulging die, sizing die etc.; Forging die, comprises die forging forging die, upsetting die etc.; And extrusion die and compression mod.
Produce a product in batches, design and manufacture a kind of suitable mould for enhancing productivity, saving production cost significant.Although mould is all kinds of various, for independent nonstandard product, or just start the product that adopts mould to produce, a design difficult problem often for mould.FERRITE CORE mainly applies in paster power inductance, and primary structure is " work " font, and namely on it, the bottom is square and is provided with spill coiling groove, and centre is square or circular center pillar.Current manufacture main technique is after horizontal lying-type powder pressing forming, then processes middle square or circular center pillar by mach mode.But along with inductance specification is more and more less, its processing is also more and more difficult.
Utility model content
The utility model is above technical problem just, there is provided a kind of and change the powder compacting mode of iron core into vertical forming by horizontal lying-type is shaping, and by the upper punch of an employing band boss and two undershoots, middle post shapes is moulded directly into directly formation of its position and puts in place, eliminate the technique of following process, thus once two molds in the FERRITE CORE that effectively can reduce iron core manufacturing cost.
The utility model is achieved through the following technical solutions:
Once two molds in FERRITE CORE, comprise upper punch, middle mould, outer undershoot, interior undershoot, it is characterized in that upper punch is arranged on above middle mould, and it is corresponding with the die cavity of middle mould centre, outer undershoot is arranged on below middle mould, and the die cavity individual with middle mould central authorities is corresponding, interior undershoot is arranged on the outside lower side of sweeping away through outer undershoot.Upper punch, middle mould, outer undershoot, interior undershoot are coaxial.Draw taper is provided with in middle mould die cavity.Middle mould die cavity is in " work " character form structure.
The utility model is due to the frame mode adopting outer undershoot, interior undershoot combines, and effectively can regulate the density of iron core middle column's part, the time processing being beneficial to FERRITE CORE is shaping, and is conducive to the demoulding of goods.When for the production of time, only needing will the bad die cavity putting into mould of material, starts lathe, carries out punching press, can complete the die cast of part respectively by upper punch, outer undershoot, interior undershoot to material is bad.
The utility model structure is simple, easy to process.
Accompanying drawing explanation
Fig. 1 is overall cutaway view of the present utility model, wherein:
1-upper punch, mould in 2-, the outer undershoot of 3-, undershoot in 4-.
Embodiment
Below in conjunction with specific embodiment, the utility model is described further.
Once two molds in FERRITE CORE, comprise upper punch 1, middle mould 2, outer undershoot 3, interior undershoot 4, it is characterized in that upper punch 1 is arranged on above middle mould 2, and it is corresponding with the die cavity of middle mould 2 centre, outer undershoot 3 is arranged on below middle mould 2, and the die cavity individual with middle mould 2 central authorities is corresponding, interior undershoot 4 is arranged on below outer undershoot 3 through outer undershoot 3.Upper punch 1, middle mould 2, outer undershoot 3, interior undershoot 4 are coaxial.Draw taper is provided with in middle mould 2 die cavity.Middle mould 2 die cavity is in " work " character form structure.
The utility model is due to the frame mode adopting outer undershoot 3, interior undershoot 4 combines, and effectively can regulate the density of iron core middle column's part, the time processing being beneficial to FERRITE CORE is shaping, and is conducive to the demoulding of goods.When for the production of time, only needing will the bad die cavity putting into mould 2 of material, starts lathe, carries out punching press, can complete the die cast of part respectively by upper punch 1, outer undershoot 3, interior undershoot 4 to material is bad.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection range of the present utility model.
Claims (4)
1. once two molds in FERRITE CORE, comprise upper punch, middle mould, outer undershoot, interior undershoot, it is characterized in that upper punch is arranged on above middle mould, and it is corresponding with the die cavity of middle mould centre, outer undershoot is arranged on below middle mould, and the die cavity individual with middle mould central authorities is corresponding, interior undershoot is arranged on the outside lower side of sweeping away through outer undershoot.
2. once two molds in FERRITE CORE according to claim 1, is characterized in that described upper punch, middle mould, outer undershoot, interior undershoot are coaxial.
