Description
Technical field
The utility model is related to a kind of hot pressing graphite jig, more particularly to a kind of hot pressing graphite mo(u)ld for powder metallurgy
Tool.
Background technology
The small graphite mould for being presently used for powder metallurgy is made up of outer sleeve, base, pressured column mostly, single
The sintered specimen shape of mould is single, once mould local damage, whole mould is scrapped immediately, these cause to cause money
The waste in source, the increase of cost.
The content of the invention
The purpose of this utility model be directed to currently used for powder metallurgy hot pressing graphite jig exist defect there is provided one
Plant many components composition, sinterable different shape sample hot pressing graphite jigs.
To achieve the above object, the utility model uses following technical scheme：
A kind of hot pressing graphite jig for powder metallurgy, including upper pressured column, mould sleeve and mold base, its feature
It is：Outer tessera and interior tessera are additionally provided with, outer tessera is located in mould sleeve, is close to mould sleeve inwall, inside inlays
Piece is located in outer tessera and is close to outer tessera inwall, and interior tessera bottom is highly more than outer tessera bottom height, mould
Base top is in step-like, and top bump sizes coordinate with outer tessera inner wall size and extend into outer tessera inwall, interior
Tessera bottom is placed in the projection of top, and the bottom of the bottom of mould sleeve and outer tessera is located at mold base top step
On.
Described outer tessera and interior tessera are all made up of two halfround bar slices.
Described upper pressurization top end has the same shape and dimensions with mold base bottom, with hot pressed sintering furnace interior
Pressurization column dimension matches.
The lower section of described upper pressured column is circular, square, triangle or other desired specimen shape；Upper pressurization
Post is stretched into interior tessera, and the shape, size with the die cavity of interior tessera are matched.
Described mold exterior sleeve is cylinder, and is matched with the size of hot pressing furnace internal cavity.
The utility model has the following advantages compared with prior art：
The size of each component of the utility model is mutually matched, and mould release is convenient, and different shape can be sintered out according to demand
Sample.Local damage need to only change primary structural component, save resource, reduce cost, extend service life, sinter out
Specimen shape rule, accurate size.
