Description
Technical field
The utility model relates to a kind of mould, specifically, is a kind of circular sample high-temperature vacuum protective atmosphere sintering mold that is used for moulding powder body material, high polymer and composite, belongs to the forming materials technical field.
Technical background
At present, the high-temperature vacuum protective atmosphere sintering mold of moulding powder body material, high polymer and composite is many, but does not have general mould.Because the model of high-temperature vacuum protective atmosphere sintering furnace is various, particularly the phenomenon of multi-use is quite general, for example: high temperature controlled atmosphere vacuum drying oven.And; there is the preparation of a very big batch sample part itself just to need through the different high temperature furnace heat processing technique of multiple tracks; usually like this, can expend a large amount of time and moneys and remove to make different moulds; because the mould process condition of producing can there are differences inevitably; so be difficult to guarantee the each uniformity of sample coupon under different process of producing, bring error for the result of the Experiment Preparation of sample.Therefore, need a kind ofly to be used for that moulding powder body material, high polymer and composite make, can satisfy that different technology conditions produces simultaneously next time, the mould of multiduty high-temperature vacuum protective atmosphere sintering.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of and can satisfy different type of furnace requirements, the circular sample high-temperature vacuum protective atmosphere sintering mold of production moulding powder body material, high polymer and composite that again can be in batches.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of circular sample high-temperature vacuum protective atmosphere sintering mold, comprise loam cake, middle part film body, base, it is characterized in that: mold integral is a cylinder, loam cake is oblate cylinder, inside, its underpart is processed with oblate cylindricality loam cake die cavity, the boss precision-fit of the die body top, middle part of loam cake die cavity and cylinder type; The boss inside of die body bottom, middle part is processed with the middle part die cavity of oblate cylindricality, the base convex platform precision-fit of middle part die cavity and base.After adopting technique scheme, at high temperature stable of the size that has guaranteed loam cake die cavity and middle part die cavity ensured the size quality of the sintered sample in the die cavity.Simultaneously, can easily product be taken out in die cavity, realize the demoulding.
In the technique scheme, the loam cake through hole UNICOM of numerous even cloth is arranged between described loam cake die cavity and the last capping; The middle part die body through hole UNICOM that numerous even cloth are arranged between the boss face of middle part die cavity and middle part die body.After adopting technique scheme; it is even to have guaranteed that loam cake die cavity and middle part die cavity are heated; the hot pressing condition unanimity; the inside cavity that enters that helps thermal current and protective atmosphere simultaneously; sample temperature in the balanced cavity has avoided die cavity directly to transmit heat to the mould material and the influence of the thermograde that produces from die wall.
In the technique scheme, the base of described cylinder type is processed with base convex platform and base lower convex platform, base lower convex platform and furnace chamber jig groove fit, and there is the base central through hole of perforation at the cylinder center of base.
As the preferred embodiment of technique scheme, the axial line of described loam cake, middle part film body, base overlaps.So size cooperates unification, and pressure is even, can guarantee the effect of product.
The beneficial effects of the utility model are: the exemplar of production all is the parallel sample for preparing in same technical process; Have comparativity, the testing result error is little; And, can adopt different protective gas to the sample in the die cavity as required, be used for high-temperature vacuum protective atmosphere sintering furnace, also can be used for vacuum cementation furnace, cvd furnace or high temperature controlled atmosphere generator multipurpose furnace, the making time and labour saving of sample spare, cost is low.

The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
Referring to Fig. 1～7, a kind of circular sample high-temperature vacuum protective atmosphere sintering mold, comprise loam cake 1, middle part film body 2, base 3, it is characterized in that: mold integral is a cylinder, loam cake 1 is oblate cylinder, inside, its underpart is processed with oblate cylindricality loam cake die cavity 4, boss 6 precision-fit of middle part die body 2 tops of loam cake die cavity 4 and cylinder type; The boss inside of die body 2 bottoms, middle part is processed with the middle part die cavity 7 of oblate cylindricality, base convex platform 10 precision-fit of middle part die cavity 7 and base 3.Loam cake through hole 5 UNICOMs that numerous even cloth are arranged between 1 of loam cake die cavity 4 and the loam cake; Middle part die body through hole 8 UNICOMs that numerous even cloth are arranged between 6 of the boss of middle part die cavity 7 and middle part die body 2.The base 3 of cylinder type is processed with base convex platform 10 and base lower convex platform 11, base lower convex platform 11 and furnace chamber jig groove fit, and there is the base central through hole 9 of perforation at base 3 cylinder centers.The axial line of described loam cake 1, middle part film body 2, base 3 overlaps.
Concrete operations are: at first put into the sample that suppresses in the middle part die cavity 7 with middle part film body 2, base convex platform 10 precision-fit with base 3 are good then; Put into the sample that suppresses again in the loam cake die cavity 4 of loam cake 1, boss 6 precision-fit with middle part die body 2 are good then; The mould that combines is put into furnace chamber, and base lower convex platform 11 is put well with furnace chamber jig groove fit.The hot-working of sample is finished in blow-on.
