Abstract
The utility model belongs to powder hot-pressing novel die, including pressure head, former, may move die sleeve, Graphite pad, base；With die sleeve for gap coordinates, die sleeve coordinates former with pressure head, base gap;Maximal clearance is no more than+0.04mm, and minimum clearance is not less than+0.007mm；Former and base close contacting fit；Pressure head compression face is circular big loading end, improves pressure head bearing capacity；Die sleeve is constituted for two and half round platform close contacting fits；The operating pressure of mould can not only be improved using this mould, moreover it is possible to solve the problems, such as that exemplar is difficult to the demoulding.
Description
Technical field
The utility model is related to powder hot forming technical field.
Background technology
In new material R＆D process, PM technique has very important effect, wherein, mould structure design
Forming quality to powder metallurgy component has a major impact, and the mould of highly effective can not only improve the property of powder metallurgy component
Can, production cost can also be reduced；And in actual production, there are problems in powder forming mould；The present inventor is new for research
Type alloy material performance is, it is necessary to first obtain alloy compressing tablet, and be to realize this purpose, it is following that inventor has found that existing mold has
Shortcoming:(1) pressure that die head can bear is smaller, alloy powder is still within relaxed state after compressing, consistency compared with
It is low；（2）Punch-pin designs unreasonable with cavity plate gap, is easily extruded in alloyed powder compression process；(3) sample after hot forming is not
Easily take out, sample is easily destroyed during taking-up.
The content of the invention
The hot pressing die that the utility model is provided, the present mold work pressure of solution is small, and exemplar is difficult to the demoulding after shaping
Problem.
The novel powder heat pressing and molding mold that the utility model is provided includes:Pressure head 1, removable die sleeve 2, former 3, graphite
Pad 4, base 6.The compression working face of the pressure head 1 is circular big loading end, can improve its bearing capacity, is matched somebody with somebody with the gap of die sleeve 2
Close.
The operating distance of the pressure head 1 is more than the height of former 3, and the height of die sleeve 2 is contour with former 3 or lower slightly.
The die sleeve 2 is that two and half round platforms contact composition, is coordinated with the gap of pressure head 1, is easy to the demoulding after shaping.
The die sleeve 2 is coordinated with former 3 with tilt angle theta gap, and wherein θ is 3 °, facilitates being put into and taking-up for die sleeve 2.
It is graphite that the die sleeve 2 and pad 5 use material.
The former 3 is hollow cylinder, and the hollow die sleeve 2 that is put into constitutes gap cooperation with it.
The thickness of the pad 5 is 5mm.
The base 6 is circle, and there is cylindrical boss at center, and boss is not higher than 1cm, is coordinated with the gap of die sleeve 2.
The base 6 is in close contact with the bottom surface of former 3, while carrying pressure, material is hard alloy.
The pressure head 1, die sleeve 2, former 3, base 6 are coaxial.
The pressure head 1, die sleeve 2, former 3, the diameter of base 6, the design of thickness are both needed to be carried out according to actual working pressure
The check of mechanical property.
The utility model with the addition of removable graphite die sleeve 2 on the basis of conventional powder heat pressing and molding mold；Avoid heat
Exemplar is difficult to release problems after pressure, and thermally equivalent when making metal dust hot pressing；There are 3 ° to incline between die sleeve 2 and former 3 simultaneously
Oblique angle, die sleeve 2 is easier to be put into former 3；Compress simultaneously after, the contact between die sleeve 2 and pressure head 1, base 6 is more tight；Avoid
Occurs the situation that molten metal bath overflows from gap when operating pressure is larger, so as to improve the operating pressure of mould；Base 6
It is designed as preventing molten metal bath from once overflowing etch machine from gap.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Specific embodiment
Specific embodiment one：Present embodiment is illustrated referring to Fig. 1；The utility model, including:It is pressure head 1, former 3, removable
Dynamic model set 2, Graphite pad 4, base 6.Wherein:
Specific embodiment two：Former 3 and the interference fits of die sleeve 2, die sleeve 2 and pressure head 1, the interference fits of base 6, other with
Specific embodiment one is identical.
Specific embodiment three：Die sleeve 2 is put into former 3 with 3 ° of inclinations angle, is compressed；So that die sleeve 2 closely connects with base 6
Touch, prevent sample 5 from overflowing, other are identical with specific embodiment one.
Specific embodiment four：Sample puts Graphite pad about 5, prevents molten metal etch mould, other and specific reality
Apply mode one identical.
The course of work：
Pressure head 1 can adjust die sleeve 2 after being put into, and die sleeve 2 is compressed downwards, so that pressure head 1, base 6 and die sleeve 2 are in hot pressing
It is fitted close in journey, had both avoided sample 5 and overflowed from gap, mold work pressure is improve again.After hot pressing, die sleeve need to only be pushed away
Go out former 3, sample 5 can stripping forming.
In sum, the utility model realizes the easy mold release of sample using packaged type graphite die sleeve, improves mould
Operating pressure.
Obviously, the structure of novel powder hot pressing die described in the utility model is not limited in above-mentioned implementation method
Concrete structure；Can also be the reasonable combination similar to the technical characteristic described in above-mentioned implementation method.
