CN203527626U - Semi-spherical soft magnetic ferrite core die - Google Patents

Abstract

The utility model discloses a semi-spherical soft magnetic ferrite core die. The semi-spherical soft magnetic ferrite core 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. The semi-spherical soft magnetic ferrite core die is characterized in that the second fixed lower male die is arranged on the lowermost layer of the semi-spherical soft magnetic ferrite core die, the movable lower male die is assembled on the second fixed lower male die, the first fixed lower male die is assembled on the movable lower male die, the female die is assembled on the first fixed lower male die, the upper male die is assembled on the uppermost layer, and the air hole is formed in the upper male die. By the adoption of the semi-spherical soft magnetic ferrite core die, a produced semi-spherical soft magnetic ferrite core is small in leakage inductance, lower in power dissipation, high in rate of finished products and low in investment cost.

Description

A kind of dome-type magnetic ferrite magnetic core mould

Technical field

The utility model belongs to soft magnet and manufactures field, particularly a kind of dome-type magnetic ferrite magnetic core mould.

Background technology

In prior art, the shape of current industry inner magnetic core, 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 carrying out mould and the Special forming machine of upper two times three.The defect existing is that product needs twice punch forming in forming process, and input cost is high.

Utility model content

For above-mentioned prior art, obtain not enoughly, the utility model provides the dome-type magnetic ferrite magnetic core that a kind of leakage inductance is little, power consumption is fallen, yield rate is high, input cost is low mould.

The utility model obtains technical scheme: a kind of dome-type magnetic ferrite magnetic core mould, comprise the fixedly fixing lower punch of lower punch, movable lower punch, second of upper male mould, pore, die, first, it is characterized in that: described dome-type magnetic ferrite magnetic core mould orlop position is provided with the second fixing lower punch, assembling activity lower punch makes progress, 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 utility model obtains beneficial effect: the design by double spherosome top circular platform, space can be utilized greatly, and leakage inductance has been accomplished infinitesimal, and power consumption drops to theoretic minimum of a value, and usefulness has reached in theory " perfect condition ".Each position consistent in density of product blank after this mould compacting, and do not change original operator scheme, save finished product.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model 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 the fixedly fixing lower punch 6 of lower punch 4, movable lower punch 5, second of upper male mould 1, die 3, first, it is characterized in that: described dome-type magnetic ferrite magnetic core mould orlop position is provided with the second fixing lower punch 6, assembling activity lower punch 5 upwards, 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 immersion die 3 in the driving of press, upper male mould 1 enters die 3 shaping areas and produces pressure, by the pore 2 assembling on upper cavity die 1, by exhaust release pressure, makes dome-type blank semicircle sphere and top circular platform consistent in density.

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 the fixedly fixing lower punch of lower punch, movable lower punch, second of upper male mould, pore, die, first, it is characterized in that: described dome-type magnetic ferrite magnetic core mould orlop position is provided with the second fixing lower punch, assembling activity lower punch makes progress, upwards assemble the first fixing lower punch, upwards assemble die, be assembled into upper male mould on, upper male mould is provided with pore.
