Abstract
The utility model is related to a kind of permanent-magnet ferrite tile-type products to suppress chamfer mould, it is characterised in that：It is to be made of punching, female die of die and mold undershoot on mold, waits for that the chamfering of die pressing product is planform shape at the chamfer site at mold undershoot edge, be made of line segment a and line segment b, the length of a, b line segment is：a≈2/3b.The utility model permanent-magnet ferrite tile-type product suppresses chamfer mould, solves the crackle that product is generated by compacting chamfering, technical guarantee is provided for the yield rate of permanent-magnet ferrite shoe-shaped product.Also support is provided for energy conservation, solves the defect problem that permanent-magnet ferrite product is generated by compacting chamfering, improves production efficiency, reduce production cost.
Description
Technical field
The utility model is related to a kind of permanent-magnet ferrite tile-type products to suppress chamfer mould.
Background technology
Currently, domestic permanent-magnet ferrite production enterprise, in the prior art, the permanent-magnet ferrite tile-type of production produce
Product, outer arc has chamfering in axial length edge, since product needs the compression moulding under magnetic field, the alignment magnetic field at chamfering because
Chamfering produces variation, i.e., alignment magnetic field produces non-continuous event, thus results in product and produce tiny split at chamfering
Line, the crack defect can only show in product after high temperature sintering, therefore the rejection rate that product occurs is more, improves life
Cost is produced, the market competition of product is unfavorable for.To solve this problem, the chamfering form of product need to be improved, can be reduced
Because of the rejection rate that product chamfering occurs, production efficiency and finished product rate are improved, it is energy saving.
Invention content
The utility model overcomes above-mentioned defect, it is therefore an objective to for improve permanent-magnet ferrite shoe-shaped product yield rate and
Production efficiency reduces production cost, is energy saving, provides a kind of permanent-magnet ferrite tile-type product compacting chamfer mould.
The utility model permanent-magnet ferrite tile-type product suppresses chamfer mould content Description：
The utility model permanent-magnet ferrite tile-type product suppresses chamfer mould, it is characterised in that：It is by punching, mold on mold
Cavity plate and mold undershoot are constituted, and wait for that the chamfering of die pressing product is planform shape at the chamfer site at mold undershoot edge, by line segment a
It is constituted with line segment b, the length of a, b line segment is：a≈2/3b.
The utility model permanent-magnet ferrite tile-type product suppresses chamfer mould, solves product because what compacting chamfering generated splits
Line provides technical guarantee for the yield rate of permanent-magnet ferrite shoe-shaped product.Also support is provided for energy conservation, solved
The defect problem that permanent-magnet ferrite product is generated by compacting chamfering, improves production efficiency, reduces production cost.
Description of the drawings
Fig. 1 is permanent-magnet ferrite tile-type product compacting chamfer mould structural schematic diagram；
Fig. 2 is permanent-magnet ferrite tile-type product compacting chamfer mould chamfer site close-up schematic view；
In figure：1 it is punching on mold, 2 be female die of die, 3 be mold undershoot, 4 is to wait for that die pressing product, 5 are chamfer sites.
Specific implementation mode
The utility model permanent-magnet ferrite tile-type product compacting chamfer mould is achieved in that do have below in conjunction with the accompanying drawings
Body explanation.
See that Fig. 1, Fig. 2, the utility model permanent-magnet ferrite tile-type product suppress chamfer mould, is by rushing 1, mould on mold
Have cavity plate 2 and mold undershoot 3 is constituted, waits for that die pressing product 4 is planform shape at the chamfer site 5 at 3 edge of mold undershoot, by line segment
A and line segment b are constituted, and the length of a, b line segment is：a≈2/3b.
The utility model permanent-magnet ferrite tile-type product suppresses the change of chamfer mould low punch chamfer shape, can improve and take
The non-continuous event generated at chamfering to magnetic field solves the crackle that product is generated by compacting chamfering, is permanent-magnet ferrite shoe
The yield rate of shape product provides technical guarantee.Also support is provided for energy conservation, solves permanent magnetic ferrite
The defect that product is generated by compacting chamfering, improves production efficiency, reduces production cost.
