Abstract
The utility model discloses a kind of cutting plate of wet pressing magnetic field forming mold of permanent-magnet ferrite magnetic shoe, it is characterised in that：Include the cutting plate with multiple die cavities, the cutting plate is provided with two or more one-to-one horizontal material holes and vertical material hole, and mutual conduction between corresponding horizontal material hole and vertical material hole, the vertical material hole is equidistantly fed by material road to each die cavity of correspondence position respectively, and each material road is not connected, check valve is separately installed with the vertical material hole.The utility model is reasonable in design, it can meet that wet pressing magnetic field forming mold of permanent-magnet ferrite magnetic shoe makes green compact arc prevent mutual string chamber between multiple material roads in shaping, cause the bad crackle such as soft angle, bad mechanical strength, while can also meet slurry not feed back in pressing process.
Description
Technical field：
Wet pressing magnetic field forming mold of permanent-magnet ferrite magnetic shoe field is the utility model is related to, relates generally to a kind of permanent magnet oxygen
The cutting plate of body magnetic shoe wet pressing pressing under magnetic field mould.
Background technology：
1. the main composition of permanent-magnet ferrite is iron oxide, the iron oxide of certain water and steel ball will be mixed with wet ball mill
Granularity 0.75-1.2um slurry is ground to, its water content control is then passed through in 37 ℅ slurry after precipitator tower precipitates
Material feeding infusion enters concave die cavity, green compact is formed in the presence of hydraulic press and magnetic field, then through high temperature sintering maturation base, finally grind
Into magnetic shoe product.
2. permanent magnetic ferrite magnetic shoe mould is mainly made up of water sucting plate, cavity plate, cutting plate, punch-pin etc..Slurry has material feeding pump
High pressure injects cutting plate material road, into concave die cavity.Die cavity is mainly made up of water sucting plate, cavity plate, punch-pin.Slurry is in shaping dope
Under press high-pressure pressure, water is discharged outside die cavity by water suction, forms green compact.
3. permanent ferrite magnetic tile product crackle is bad mainly have shaping bad caused by, currently known cutting plate passes through
Drilled on cutting plate, form material road.And each material road is mutually conducted, and does not have check valve in cutting plate, such slurry exists
In press pressing process, due to being flexible pipe between mould and feeding machine, easily expansion, causes feed back.Produce green compact crackle.
Utility model content：
A kind of the defects of the utility model purpose is exactly to make up prior art, there is provided permanent ferrite magnetic tile wet pressing magnetic
The cutting plate of field mould, it is more can to meet that wet pressing magnetic field forming mold of permanent-magnet ferrite magnetic shoe prevents green compact arc in shaping
String chamber, while can also meet slurry not feed back in pressing process mutually between individual material road.
The utility model is achieved through the following technical solutions：
A kind of cutting plate of wet pressing magnetic field forming mold of permanent-magnet ferrite magnetic shoe, it is characterised in that：Include with multiple
The cutting plate of die cavity, the cutting plate are provided with two or more one-to-one horizontal material holes and vertical material hole,
And mutual conduction between corresponding horizontal material hole and vertical material hole, the vertical material hole is respectively by material road to corresponding position
The each die cavity put equidistantly is fed, and each material road is not connected, and check valve is separately installed with the vertical material hole.
The surrounding of described material road is respectively equipped with the seal groove coordinated with it, and sealing ring is installed with the seal groove.
Spring is installed, the spring is fixed on cavity plate in the vertical direction of described check valve.
The utility model has the advantages that：
The utility model is reasonable in design, can meet that wet pressing magnetic field forming mold of permanent-magnet ferrite magnetic shoe makes in shaping
Green compact arc prevents mutual string chamber between multiple material roads, causes the bad crackle such as soft angle, bad mechanical strength, while can also meet slurry
The not feed back in pressing process.
Brief description of the drawings：
Fig. 1 is top view of the present utility model；
Fig. 2 is the fragmentary sectional view in Fig. 1；
Embodiment：
Referring to accompanying drawing.
A kind of cutting plate of wet pressing magnetic field forming mold of permanent-magnet ferrite magnetic shoe, includes the cutting plate with multiple die cavities
1, the cutting plate 1 is provided with two one-to-one horizontal material holes 2 and vertical material hole 3, and corresponding horizontal material hole 2
The mutual conduction between vertical material hole 3, the vertical material hole 3 is respectively by material road 4 to each die cavity of correspondence position etc.
Away from feed, and each material road 4 is not connected, and check valve 5 is separately installed with the vertical material hole 3.
The surrounding of described material road 4 is respectively equipped with the seal groove 6 coordinated with it, and sealing ring is installed with the seal groove 6.
Spring 7 is installed, the spring 7 is fixed on cavity plate in the vertical direction of described check valve 5.
, there is diameter 12 a diameter of the 18 of two described horizontal charge holes between the check valve of horizontal charge hole and diameter 20
Vertical material hole.Slurry, into wide 18 deep 22 material roads, enters back into die cavity by wide 12 deep 22 material roads.Material road surrounding is opened wide by 4 respectively
Deep 2.9 seal grooves, sealing ring is between cutting plate and cavity plate.Unit is mm.
Its principle is：
1. the slurry of magnetic shoe mould enters material road by entering horizontal material hole, then by vertical material hole, because material road
It is not turned on mutually effectively preventing material road from altering chamber, material road, which alters chamber, can produce die cavity slurry unsaturation, cause soft angle, bad mechanical strength etc.
Bad crackle.And material feeding check valve is housed in material road, check valve effectively prevents material road feed back, prevents product from batch turning occur and showing
As.
2. processing material road on the cutting plate of magnetic shoe mould, material road surrounding has seal groove, and material road import has check valve respectively.
Material road import is equidistant to each die cavity respectively.And two material roads independently structure, chamber is not altered mutually.Cavity can be prevented
Each die cavity green density of mould it is inconsistent, while can also prevent single die cavity slurry fills out unreal phenomenon.Ensure each die cavity base
The uniformity of volume density, effectively prevent that magnetic shoe green density is uneven, improve the mechanical strength of magnetic shoe finished product.
