Description
Technical field
This utility model relates to a kind of mould, is specifically related to a kind of layering sintering mold for vacuum hotpressing stove.
Background technology
Bulky powder that hot pressed sintering refers to be opposite to limit in the graphite jig of shape or same to powder compact heating
Time to its apply uniaxial tension sintering process.During due to hot pressing, powder is in hot plastic state, and deformation resistance is little, it is easy to mould
Property flowing and densification, therefore, its required briquetting pressure is only the 1/10 of cold-press method, may be used for the large-sized pottery of molding
Product.And, during hot pressed sintering, owing to heating, pressurizeing simultaneously, contribute to contact and diffusion, the flowing etc. of powder particle
Mass transport process, reduces sintering temperature and shortens sintering time, thus inhibiting growing up of crystal grain, and therefore, pressure sintering is readily obtained
Close to solid density, the porosity close to the sintered body of zero, be readily obtained compact grained tissue, it is achieved the orientation effect of crystal and
Control by the change that forms of high vapour pressure composition nanosystems, thus be readily obtained and there is good mechanical performance, electric property
Product, and be applicable to produce shape is complex, size is the finest product.But, by hot pressing furnace inner chamber size
Limiting, existing single heat batch is less, thus causes production efficiency can not meet the requirement of industrialized mass.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of layering for hot pressing furnace sinters mould
Tool, it can improve the batch of single heat, thus improve production efficiency.
For achieving the above object, this utility model is by the following technical solutions:
A kind of layering sintering mold for hot pressing furnace, including sintering mold, wherein: described sintering mold includes outer jacket
And it is located at the backing board bottom outer jacket, the inwall along described outer jacket is provided with an interior lining panel, and described interior lining panel is described
Form a cavity in outer jacket, in described cavity, be provided with at least one piece of dividing plate along the radial arrangement of this cavity from top to bottom,
And the top of described dividing plate is additionally provided with a briquetting.
Preferably: described cavity is truncated cone-shaped.
Preferably: the tapering of described cavity is 0.1%-1%.
Preferably: described cavity is square.
Preferably: described dividing plate is spaced set in described cavity.
Preferably: described dividing plate is graphite septum.
Preferably: described layering sintering mold also includes pre-pressing die, wherein, described pre-pressing die include prefabricating plate with
And it is positioned at the pre-depression bar of described prefabricating plate end face.
Preferably: the bottom surface of described prefabricating plate is concave surface.
Preferably: the concavity of described concave surface is 0.2%-0.8%.
The beneficial effects of the utility model are, sintering mold of the present utility model by arrange in sintering cavity every
Plate, becomes monolayer sintering into multi-layer sintering, improves the batch of single heat, thus correspondingly improves production efficiency.Pass through
The interior lining panel that thickness of slab from top to bottom is sequentially reduced is set, to form a truncated cone-shaped or square cavity in jacket outside, thus can drop
During low frit, frictional force between interior lining panel and dividing plate when dividing plate moves down.And by bottom surface, there is the pre-of certain concavity
Pressing plate, can make the shape through the ceramic powder formation of precompressed with convex surface, change the stress distribution of sintering process median septum, fall
The probability that low partition bends or crushes.And, pass through precompressed, it is also possible to reduce the height of every layer of powder, increase dress bisque
Number, thus improve single furnace output further.
