Description
Technical field
The utility model belongs to technical field of mold, and in particular to a kind of breakdown pressure sintering graphite jig.
Background technology
As the continuous progress of powder metallurgical technique, the application of pressure sintering are more and more common.To ensure to have sintered
Final product quality, typically ensures profile and sintering pressure using graphite sintering mould, and mould is using extremely wide in industrial production
Underlying process equipment, mould industry is the basic industries of national economy.In modern industrial production, product parts are widely used
Punching press, excellent suitability for press forming, casting forming, extrusion molding, plastic injection or other forming and machining methods, match with shaping dies,
Make blank forming into the part for meeting product requirement.The various instruments arrived used in our daily production and lifes and production
Product, big base, the fuselage cover for arriving lathe, the shell of small to one embryo head screw, button and various household electrical appliance, invariably with
Mould has close relationship.The shape of mould decides the profile of these products, and the crudy of mould is also just determined with precision
Determine the quality of these products.In recent years die industry develops rapidly, and graphite material, new technology and ever-increasing Die ＆ Mould Manufacture are not
Disconnected to impact Die ＆ Mould Market, graphite is increasingly becoming the preferred material of Mold Making with its good physical and chemical properties.
Conventional sintering mould uses integral manner, according to shape of product, makes product design with overall graphite, is then placed in
Product is sintered, subsequent forced stripper mechanism, and the technique is low per furnace output, and product stripping is cumbersome, and graphite jig is easily damaged,
More, die cost height is taken in production process.
Utility model content
The purpose of this utility model is to provide a kind of breakdown pressure sintering graphite jig, to solve above-mentioned background skill
The problem of product stripping proposed in art is cumbersome, and graphite jig is easily damaged, time-consuming more in production process, and die cost is high.
To achieve the above object, the utility model provides following technical scheme：A kind of breakdown pressure sintering graphite mo(u)ld
Tool, including lower connection high-strength graphite bolt, mould inner sleeve, die head, upper connection high-strength graphite bolt, die coat, it is described
Die coat upper and lower ends are respectively symmetrically provided with lower connection high-strength graphite bolt and upper connection high-strength graphite bolt, and outside mould
The inner homogeneous of set is provided with mould inner sleeve, and the side of the mould inner sleeve is provided with die head.
Preferably, the number of the mould inner sleeve can be changed according to the actual requirements.
Preferably, the die coat is split-type structural.
Preferably, the mould inner sleeve is split-type structural.
Compared with prior art, the beneficial effects of the utility model are：The utility model is scientific and reasonable for structure, safe to use
Convenient, the mould inner sleeve and die coat of this graphite jig use split-type design, and die coat passes through the lower high-strength stone of connection
Black bolt and upper connection high-strength graphite are bolted together, and facilitate product stripping, this mould employs the multigroup design of a mould, had
Effect utilizes sintering space, increases per stove sintering output, and does not allow easy damaged graphite inwall in the demoulding, and mould inner wall is more prone to
Cleaning, production efficiency is improved, reduces die cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：Connected under 1- high-strength graphite bolt, 2- moulds inner sleeve, 3- die heads, connect on 4- high-strength graphite bolt,
5- die coats.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, the utility model provides a kind of technical scheme：A kind of breakdown pressure sintering graphite jig, bag
Include lower connection high-strength graphite bolt 1, mould inner sleeve 2, die head 3, upper connection high-strength graphite bolt 4, die coat 5, mould
The upper and lower ends of overcoat 5 are respectively symmetrically provided with lower connection high-strength graphite bolt 1 and upper connection high-strength graphite bolt 4, and outside mould
The inner homogeneous of set 5 is provided with mould inner sleeve 2, and the side of mould inner sleeve 2 is provided with die head 3.
In order that this mould scope of application is wider, in the present embodiment, it is preferred that the number of mould inner sleeve 2 can be according to reality
Border demand is changed.
In order to save the die-filling and striking time of this mould, in the present embodiment, it is preferred that die coat 5 is split type knot
Structure.
In order to save the die-filling and striking time of this mould, in the present embodiment, it is preferred that mould inner sleeve 2 is split type knot
Structure.
Operation principle and process for using of the present utility model：After the breakdown pressure sintering is installed with graphite jig,
Die coat 5 is fixed by lower connection high-strength graphite bolt 1 and upper connection high-strength graphite bolt 4, material is injected into mould
In cavity in inner sleeve 2, compressed by die head 3, after shaping, by lower connection high-strength graphite bolt 1 and the upper high-strength stone of connection
Black bolt 4 is pulled down, and separates die coat 5, then mould inner sleeve 2 is separated, and takes out die head 3, so that it may directly take product
Go out, this mould employs the multigroup design of a mould, effectively using sintering space, increases per stove sintering output, and does not allow in the demoulding
The inwall of easy damaged mould inner sleeve 2, the inwall of mould inner sleeve 2 are more prone to clear up, improve production efficiency, reduce mould into
This.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
