Abstract
The utility model discloses a multilevel graphite mould for a vacuum hotpressing furnace, which comprises a lower pressing head and at least one group of layering mould, wherein the layering mould comprises a mould sleeve and a spacer layer which is pressed on the mould sleeve and has raised upper and lower surfaces; the mould sleeve at the bottommost layer is sheathed on the lower pressing head; and the spacer layer is connected with the vertical adjacent mould sleeves. As for the mould provided by the utility model, the product density and thickness are uniform, the graphite mould can be detached and can be replaced independently, the height of the mould can be adjusted according to the size of a furnace body, and a plurality of products can be pressed simultaneously, so that the hot pressing efficiency is improved.
Description
Technical field
The utility model relates to a kind of hot pressed sintering graphite jig, relates in particular to the multi-level graphite jig of a kind of vacuum hotpressing stove.
Background technology
Hot pressed sintering be meant in being opposite to the graphite jig that limits shape bulky powder or in the powder compact heating to its sintering process that applies uniaxial tension, be important a kind of in the material sintering process such as pottery and Wimet.
Hot pressed sintering carries out simultaneously owing to heating and pressurizing, powder is in the thermoplasticity state, the carrying out that helps particulate contact diffusion, the mass transfer process that flows, reduce sintering temperature and shorten sintering time, thereby resistance grain growth, obtain that crystal grain is tiny, density is high and mechanics, the high good product of electric property, but because this method is with the powder die cavity of directly packing into, thereby exist goods and be easy to disadvantages such as mould intracavity wall adhesion, mold damage, product amount owing to the each production of existing single mode mould is few in addition, thereby its production efficiency is low, cost is high.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model purpose is to provide a kind of separate, the high efficiency, low cost hot pressed sintering graphite jig that can be recycled.
The technical solution of the utility model is: the multi-level graphite jig of a kind of vacuum hotpressing stove, comprise push-down head, also comprise at least one group of layering mould that constitutes by die sleeve and the pressure separate layer of two-sided projection up and down thereon, wherein undermost die sleeve is placed on the push-down head, and separate layer is accepted neighbouring die sleeve.
As preferably, the void pitch between separate layer and its adjacent die sleeve in below is greater than the stroke of individual layer pressure head in the hot pressing.
The beneficial effects of the utility model are: in hot-pressed sintering furnace, can multi-level layering mould be set according to the body of heater height, enhance productivity; Powder in each die sleeve is separate in addition, and the product specification of compacting influences invariably; When disadvantage such as the adhesion of die sleeve mould intracavity wall, mold damage occurring, can according to circumstances change die sleeve separately, save cost, and continuing and circulation of realizing producing.

Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1 push-down head, 2 die sleeves, 3 separate layers, 4 loading areas
Embodiment
As a kind of embodiment of the present utility model, as shown in Figure 1, the multi-level graphite jig of a kind of vacuum hotpressing stove, comprise push-down head 1, also comprise at least one group of layering mould that constitutes by die sleeve 2 and the pressure separate layer 3 of two-sided projection up and down thereon, wherein undermost die sleeve 2 is placed on the push-down head 1, and separate layer 3 is accepted neighbouring die sleeve 2.The separate layer 3 of two-sided projection serves as the upper and lower pressure head and the junctor of adjacent die sleeve 2, thereby forms relatively independent layering mould.As shown in this embodiment, the utility model adopts three high graphite to make, and totally is two-layer layering mould, by push-down head 1, and die sleeve 2, separate layer 3 is formed, 2 of push-down head 1 and die sleeves, and die sleeve 2 and 3 formation of separate layer loading area 4.Mould is according to the charging of from top to bottom order, and in the die cavity with the die sleeve 2 for the treatment of to pack into after the press-powder material isostatic cool pressing, separate layer 3 convex parts are put into the die cavity of die sleeve 2, then put another die sleeve 2 on separate layer 3 again, so circulate.According to body of heater and mold height, the multi-level powder of packing into.In addition, the void pitch between separate layer 3 and its adjacent die sleeve 2 in below is avoided hot pressing die sleeve 2 and separate layer 3 both sides pressings greater than the stroke of individual layer pressure head in the hot pressing, influences pressure transmission.
Claims (2)
1. multi-level graphite jig of vacuum hotpressing stove, comprise push-down head, it is characterized in that: also comprise at least one group of layering mould that is made of die sleeve and the pressure separate layer of two-sided projection up and down thereon, wherein undermost die sleeve is placed on the push-down head, and separate layer is accepted neighbouring die sleeve.
2. the multi-level graphite jig of a kind of vacuum hotpressing stove according to claim 1 is characterized in that: the void pitch between separate layer and its adjacent die sleeve in below is greater than the stroke of individual layer pressure head in the hot pressing.
