Abstract
The utility model discloses a sintering fixture for metal powder injection molding. The sintering fixture is used for sintering sliding arms, and comprises fixture bodies and a saggar, wherein each fixture body is rectangular, and the upper side of each fixture body has a shape of an arch bridge; a plurality of sliding arms are arranged on one fixture body; and a plurality of fixture bodies are arranged in the saggar. The sintering fixture for the metal powder injection molding can prevent the deformation of the sliding arms which are subjected to the metal powder injection molding and sintered effectively, so that the production efficiency can be improved substantially.
Description
Technical field
The utility model relates to a kind of sintering tool, particularly relates to a kind of metal powder injection molding sintering tool that is used for travelling arm.
Background technology
Metal powder injection molding technology (Metal Powder Injection Molding is called for short MIM) is the metallurgical forming technique of a novel powder that modern plastics injection molding technology introducing field of powder metallurgy is formed.
MIM technology 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 that fine metal dust and organic binder bond are uniformly mixed into to 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 it highly dense, become metallic article subsequently through sintering.But product is before sintering, and especially the state after removing binding agent is very fragile.For the travelling arm product, volume is little and shape is special especially, use conventional corundum piece to assist to support to be easy to produce crooked, subside etc., thereby cause the scrappage of product very high.And because travelling arm 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.
The utility model content
The technical problem that the utility model mainly solves provides a kind of metal powder injection molding sintering tool, can prevent effectively that travelling arm is out of shape behind the metal powder injection molding sintering, and can significantly enhance productivity.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of metal powder injection molding sintering tool is provided, is used for the sintering of travelling arm, comprising: tool body and saggar; Said tool body is a rectangle; Said tool body top is arch-shaped, is placed with a plurality of travelling arms on the tool body, places a plurality of tool bodies in the said saggar.
In preferred embodiment of the utility model, said tool body is an aluminium oxide ceramics.
In preferred embodiment of the utility model, said a plurality of tool bodies are arranged side by side.
In preferred embodiment of the utility model, the arch-shaped structure of said tool body top is identical with the arm body structure of travelling arm.
In preferred embodiment of the utility model, the material of said saggar is a corundum-mullite.
The beneficial effect of the utility model is: the utility model metal powder injection molding sintering tool is owing to the special shape according to the travelling arm product designs; Can effectively prevent the product sintering warpage; It is very simple that goods of furniture for display rather than for use work becomes; Depositing of product seems more in good order, and favourable field management has improved production efficiency.
Description of drawings
Fig. 1 is the perspective view of the utility model metal powder injection molding sintering tool;
Fig. 2 is the decomposing schematic representation of the utility model metal powder injection molding sintering tool one preferred embodiment.
The mark of each parts is following in the accompanying drawing: 1, tool body; 2, saggar; 3, travelling arm.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1 and Fig. 2; The utility model embodiment comprises: a kind of metal powder injection molding sintering tool, be used for the sintering of travelling arm, and comprising: tool body 1 and saggar 2; Tool body 1 is a rectangle; Tool body 1 top is arch-shaped, and tool body 1 top is placed with a plurality of travelling arms 3, places a plurality of tool bodies 1 in the saggar 2.The material of saggar 2 is corundum-mullite in addition, and is high temperature resistant, has certain heat endurance, is the excellent protective container.
Further, said tool body 1 is an aluminium oxide ceramics, and a plurality of tool bodies 1 are arranged side by side, can be high temperature resistant when the metal injection moulding sintering.The arch-shaped structure of tool body 1 top is identical with the arm body structure of travelling arm 3; Because the curved surface radian of tool is consistent with product; Product shrinks according to the radian of subscribing when high temperature sintering; Sintering finishedly can not deform during to metallic state, be very beneficial for the dimensional accuracy of travelling arm behind the metal injection moulding.
The course of work of the utility model metal powder injection molding sintering tool; At first will extract the travelling arm of accomplishing 3 is positioned on the sintering tool body 1 one by one; Put two travelling arms 3 on each tool body 1; The sintering tool body 1 of the travelling arm of having put 3 totally four directly put into saggar 2 again, add upper cover plate for saggar 2, promptly can put into graphite vacuum drying oven sintering.
The utility model metal powder injection molding sintering tool is different from prior art: replace conventional sintering tool, design the sintering tool identical with product structure, specially tool is special-purpose, has reduced the scrappage of product.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification 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 utility model.
