Abstract
The invention discloses a sintering fixture for a size exhaust pipe baffle formed by injecting metal powder. The sintering fixture comprises sintering pans, wherein the sintering pans comprise a large sintering pan and a small sintering pan; steps are respectively arranged on the large sintering pan and the small sintering pan; the steps are attached and fixedly arranged above the large sintering pan and the small sintering pan; and square grooves are formed in two end parts at the middles of the large sintering pan and the small sintering pan respectively. Due to the adoption of the mode, according to the sintering fixture for the size exhaust pipe baffle formed by injecting the metal powder, the sintering deformation of size exhaust pipe baffle products formed by injecting the metal powder can be effectively prevented, so that the part placement work becomes simple and further the production efficiency is increased; and the more-orderly storage of the products is realized, and thus the field management is facilitated.
Description
Technical field
The present invention relates to the metal powder injection molding technical field, particularly relate to a kind of metal powder injection molding size blast pipe baffle plate and use the sintering tool.
Background technology
Metal powder injection molding is a new forming technique that develops rapidly in the world in recent years, it is advantageous that the small-sized parts that can form any complicated shape, and each position density of goods is even, excellent performance.
General technological process is for to be uniformly mixed into fine metal dust and organic binder bond for having the material of rheological characteristic; The die cavity that adopts advanced injector injection to have part shape forms blank; Through removing binding agent and, making its high compaction, become metallic article subsequently through sintering.
But product is before sintering, and especially the state after removing binding agent is very fragile.Particularly for blast pipe baffle plate product, volume is little and shape is special, use conventional corundum piece to assist to support to be easy to produce crooked, subside etc., thereby cause scrapping of product.And because blast pipe baffle plate product quantity is many, fixing placing attitude again during sintering needs the labor manpower that product is correctly put one by one, has reduced production efficiency.
In order to address the above problem, to have designed a kind of sintering tool of uniqueness and placed big or small blast pipe baffle plate product.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of metal powder injection molding size blast pipe baffle plate and uses the sintering tool; Can effectively prevent the sintering warpage of metal powder injection molding blast pipe baffle plate product; Make goods of furniture for display rather than for use work become simple; Improved production efficiency, depositing of product is also more in good order, helps field management more.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: provide a kind of metal powder injection molding size blast pipe baffle plate to use the sintering tool, and, comprising: sintering pan; Sintering pan comprises big sintering pan and little sintering pan; Be provided with step on big sintering pan and the little sintering pan, step is fitted and is fixedly installed on big sintering pan and little sintering pan top, and two ends of middle all offer square groove on big sintering pan and the little sintering pan.
In preferred embodiment of the present invention, said big or small sintering pan profile is all rounded.
In preferred embodiment of the present invention, the specification of said big sintering pan is R36.5mm*5mm, and the specification of little sintering pan is R33mm*5mm.
In preferred embodiment of the present invention, the height that said big or small sintering pan is topped bar is 8.3mm ~ 8.5mm.
The invention has the beneficial effects as follows: metal powder injection molding size blast pipe baffle plate of the present invention can effectively prevent the sintering warpage of metal powder injection molding blast pipe baffle plate product with the sintering tool; Make goods of furniture for display rather than for use work become simple; Improved production efficiency; Depositing of product is also more in good order, helps field management more.
Description of drawings
Fig. 1 is the structural representation of metal powder injection molding size blast pipe baffle plate of the present invention with one preferred embodiment of sintering tool;
The mark of each parts is following in the accompanying drawing: 1, big sintering pan, 2, step, 3, square groove.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the embodiment of the invention comprises:
A kind of metal powder injection molding size blast pipe baffle plate is used the sintering tool,, comprising: sintering pan 1, sintering pan comprise big sintering pan and little sintering pan, big or small sintering pan profile is all rounded.
Be provided with step 2 on said big sintering pan and the little sintering pan, the height of step 2 is 8.3mm ~ 8.5mm.Preferably, shoulder height is 8.5mm.
Said step 2 is fitted and is fixedly installed on big or small sintering pan top, and two ends of middle all offer square groove 3 on big sintering pan and the little sintering pan.
After using this kind to be used for sintering tool that big or small blast pipe baffle plate uses, can effectively prevent the sintering warpage of product, make goods of furniture for display rather than for use work become simply simultaneously, improve production efficiency, guarantee that depositing of product seems more in good order, help field management.
Particularly, the specification of said big sintering pan is R36.5mm*5mm, and the specification of little sintering pan is R33mm*5mm, all adopts aluminium oxide ceramics to process.
Among the present invention; Because manufacturing materials is an aluminium oxide ceramics; High temperature during can be anti-metal injection molded sintering, and because the face shaping and the product of tool are consistent, product shrinks according to reservation shape when high temperature sintering; Sintering finishedly can not deform during to metallic state, help the dimensional accuracy of metal injection molded blast pipe baffle plate.
The course of work of the present invention is:
The product that extraction is accomplished is placed on the sintering tool one by one, puts a product on each tool, puts the sintering tool of product and directly puts on the graphite cake, promptly can put into graphite vacuum drying oven sintering.
Metal powder injection molding size blast pipe baffle plate of the present invention with the beneficial effect of sintering tool is:
Can effectively prevent the sintering warpage of metal powder injection molding blast pipe baffle plate product, make goods of furniture for display rather than for use work become simply, improve production efficiency, depositing of product is also more in good order, helps field management more.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
