Abstract
The invention discloses a die for hemispherical soft magnetic ferrite cores. The die comprises an upper male die, an air hole, a female die, a first fixed lower male die, a movable lower male die and a second fixed lower male die, and is characterized in that the second fixed lower male die is arranged at the lowermost-layer position of the die for the hemispherical soft magnetic ferrite cores, the movable lower male die is upwardly assembled, the first fixed lower male die is upwardly assembled, the female die is upwardly assembled, the upper male die is assembled at the uppermost position of the die, and the air hole is formed in the upper male die. The die for the hemispherical soft magnetic ferrite cores has the advantages that the hemispherical soft magnetic ferrite cores manufactured by the aid of the die are low in leakage inductance, power consumption can be reduced, and the die is high in yield and low in input cost.
Description
Technical field
The invention belongs to soft magnet and manufacture field, particularly a kind of dome-type magnetic ferrite magnetic core mould.
Background technology
In prior art, the shape of industry inner magnetic core at present, for example EP type, EPC type, tank shape product due to the limitation of product structure, exist defect in leakage inductance and eddy-current loss.And dome-type magnetic ferrite magnetic core is made this product by the mould and the Special forming machine that carry out upper two times three.The defect existing is that product needs twice punch forming in forming process, and input cost is high.
Summary of the invention
Obtain not enoughly for above-mentioned prior art, the invention provides the dome-type magnetic ferrite magnetic core mould that a kind of leakage inductance is little, power consumption is fallen, yield rate is high, input cost is low.
Technical scheme of the present invention is: a kind of dome-type magnetic ferrite magnetic core mould, comprise upper male mould, pore, die, the first fixing lower punch, movable lower punch, the second fixing lower punch, it is characterized in that: described dome-type magnetic ferrite magnetic core mould orlop position is provided with the second fixing lower punch, upwards assembling activity lower punch, upwards assemble the first fixing lower punch, upwards assemble die, be assembled into upper male mould on, upper male mould is provided with pore.
The invention has the beneficial effects as follows: by the design of double spherosome top circular platform, space can be utilized greatly, leakage inductance has been accomplished infinitesimal, and power consumption drops to theoretic minimum of a value, and usefulness has reached in theory " perfect condition ".The each position of product blank consistent in density after this mould compacting, and do not change original operator scheme, save finished product.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of dome-type magnetic ferrite magnetic core mould, comprise upper male mould 1, die 3, the first fixing lower punch 4, movable lower punch 5, the second fixing lower punch 6, it is characterized in that: described dome-type magnetic ferrite magnetic core mould orlop position is provided with the second fixing lower punch 6, upwards assembling activity lower punch 5, upwards assembles the first fixing lower punch 4, upwards assembles die 3,, be assembled into upper male mould 1, upper male mould 1 is provided with pore 2.
Using method:
1) after die 3 chargings, upper male mould 1 moves down and immerses die 3 in the driving of press, upper male mould 1 enters die 3 shaping areas and produces pressure, by exhaust release pressure, makes dome-type blank semicircle sphere and top circular platform consistent in density by the pore 2 assembling on upper cavity die 1.
2) upper male mould 1 presses down with die 3 simultaneously, and dome-type blank semiglobe is formed.
3) on fixing movable lower punch 5, move, dome-type blank centre-pillar structure is formed;
4) die 3 stops, and upper male mould 1 presses down again, and dome-type blank low side ledge structure is formed.
Claims (1)
1. a dome-type magnetic ferrite magnetic core mould, comprise upper male mould, pore, die, the first fixing lower punch, movable lower punch, the second fixing lower punch, it is characterized in that: described dome-type magnetic ferrite magnetic core mould orlop position is provided with the second fixing lower punch, upwards assembling activity lower punch, upwards assemble the first fixing lower punch, upwards assemble die, be assembled into upper male mould on, upper male mould is provided with pore.
