Description
Technical field
The utility model is related to magnetic powder field shaping technique, specifically a kind of aluminium-nickel-cobalt magnetic comminuted steel shot press-moulding die.
Background technology
Powder product can be widely applied to communication, the energy, auto industry, household appliances, automatic door control and inductor,
In the production of the various electronic components such as filter, mutual inductor, inverter, especially in last century the nineties, Switching Power Supply
This new product is used by large-scale popularization.As a kind of excellent inductance core, on various switch power modules, largely used
It filters, current stabilization, the various inductance elements such as energy storage.
Country's industry all carries out alnico magnet powder compacting, foundation using the method for block mold single compacting at present
The operating pressure of the size setting press of magnet steel press face, it is that the 2.5-4 tons/side cm2 can generally to require working unit pressure
The green density of powder compacting is set to meet product technology requirement.Since mold fills the vacancy of dispersed-powder determination techniques, at
The problem of magnet steel powder is not easy to ensure the uniformity of magnetic powder density in pattern tool, and crackle, fracture easily occur for product after die casting, influences
The raising of yields.
Invention content
The purpose of this utility model is to provide a kind of aluminium-nickel-cobalt magnetic comminuted steel shot press-moulding dies, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the utility model provides the following technical solutions：
A kind of aluminium-nickel-cobalt magnetic comminuted steel shot press-moulding die, including：Cope plate, lower template, top sealing plate and vibrating head, under described
Template is located at immediately below cope plate；Cope plate uses concave structure, the top sealing plate to be fixedly welded in the groove of cope plate,
It is respectively arranged with trough rim and lower trough rim in several groups on cope plate and top sealing plate, upper trough rim is corresponding with lower trough rim position, upper trough rim
Cavity is formed between lower trough rim, fills jolt-packing in cavity, the vibrating head is wrapped in jolt-packing.
As further program of the utility model：The side of cope plate also sets up side seal board, is arranged on side seal board and is used for
The mounting hole of vibrating head is installed.
As further program of the utility model：It is connected and fixed using connector between cope plate and side seal board.
As further program of the utility model：Rubber pad interlayer is also set up between side seal board and cope plate.
As further program of the utility model：The jolt-packing uses non-metal powder.
Compared with prior art, the utility model has the beneficial effects that：The molding die of the utility model is to alnico
Before magnet steel powder compression moulding, vibration dispersion is carried out to powder using vibrating head, makes its even density, can effectively reduced close because suppressing
Crackle, breakage problem caused by degree is uneven improve yields.

Fig. 2 is a kind of overlooking structure diagram of aluminium-nickel-cobalt magnetic comminuted steel shot press-moulding die.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Please refer to Fig.1~2, in the utility model embodiment, a kind of aluminium-nickel-cobalt magnetic comminuted steel shot press-moulding die, including：On
Template 1, lower template 5, top sealing plate 2 and vibrating head 4, the lower template 5 are located at immediately below cope plate 1, and alnico magnet can be filled
Powder；Cope plate 1 uses concave structure, the top sealing plate 2 to be fixedly welded in the groove of cope plate 1, cope plate 1 and closedtop
Trough rim 21 and lower trough rim 11 in several groups are respectively arranged on plate 2, upper trough rim 21 is corresponding with lower 11 position of trough rim, upper trough rim 21 with
Cavity is formed between lower trough rim 11, fills jolt-packing 3 in cavity, the vibrating head 4 is wrapped in jolt-packing 3, and vibration is filled out
Material 3 is non-metal powder, if fineness is less than the talcum powder that 100 mesh sieve, can play the effect of conduct vibrations；The side of cope plate 1
Side seal board 7 is also set up, the mounting hole being arranged for installing vibrating head 4 on side seal board 7 will shake after being welded and fixed top sealing plate 2
Dynamic stick 4 is sent into cavity, and fills the compacting of jolt-packing 3, and side seal board 7 is fixed, and during die cast, cope plate 1 is transported
It moving to the cavity of lower template 5, Vibration on Start-up stick 4 conducts the vibration for making cope plate 1 generate frequency low-amplitude by jolt-packing 3,
Make the magnet steel powder in cavity is vibrated to be uniformly dispersed, ensures that magnet steel powder density is uniform in cavity, to product after compacting
