Description
Technical field
The present invention relates to sintering tool technical field, particularly relate to a kind of metal powder injection molding sintering tool.
Background technology
Metal Injection Molding is a kind of novel manufacturing process technology combined with plastics forming technique by powder metallurgy, and it is first to be mixed with binding agent by selected powder, the shape required for the injection moulding again that then undertaken compound granulating.Get rid of binding agent after molding, then defat base is sintered.But, product is before sintering, especially very fragile after elimination binding agent, especially to having erose blank, it is easy to produce the deformation such as fracture, bending, displacement, thus causing scrapping of product；And when blank quantity is more, sintering needs again fixing placing attitude, it is necessary to expending a large amount of manpower and correctly put one by one by product, production efficiency is relatively low.
Summary of the invention
The purpose of the present invention is to propose to a kind of metal powder injection molding sintering tool, to solve, blank SINTERING PRODUCTION efficiency is low is susceptible to deformation, the problem that scrappage is high with product.
For reaching this purpose, the present invention by the following technical solutions:
A kind of metal powder injection molding sintering tool, including jig body, described jig body has the support platform for supporting workpiece to be sintered, and described jig body is provided with locating slot, is used for fixing workpiece to be sintered.
Sinter the preferred version of tool as a kind of metal powder injection molding, described jig body is sintering pan, and the profile of the profile of described sintering pan and workpiece to be sintered matches.
Sinter the preferred version of tool as a kind of metal powder injection molding, the profile of described sintering pan is rounded.
Sinter the preferred version of tool as a kind of metal powder injection molding, the external diameter of described sintering pan is be more than or equal to the external diameter of workpiece to be sintered.
Sinter the preferred version of tool as a kind of metal powder injection molding, described locating slot is at least one open slot being opened in sintering pan outer rim, and described workpiece to be sintered is provided with at least one boss matched with open slot.
Sinter the preferred version of tool as a kind of metal powder injection molding, described open slot has two, and two open slots are symmetricly set on sintering pan.
Sinter the preferred version of tool as a kind of metal powder injection molding, described sintering pan is hollow structure.
Sinter the preferred version of tool as a kind of metal powder injection molding, the material of described jig body is aluminium oxide or zirconium oxide.
The invention have the benefit that
The present invention proposes a kind of metal powder injection molding sintering tool, workpiece to be sintered can be fixed on the support platform of jig body by locating slot, the workpiece to be sintered extracted is placed on one by one on sintering tool, each tool is put a workpiece to be sintered, puts into vacuum drying oven afterwards and sinter.Present configuration is simple, it is possible to effectively prevent the sintering warpage of metal powder injection molding product so that goods of furniture for display rather than for use work becomes simple, improves production efficiency, and depositing of product is also more in good order, advantageously in field management.

Detailed description of the invention
For the technical scheme making to present invention solves the technical problem that, adopting and the technique effect reached clearly, below in conjunction with accompanying drawing, the technical scheme of the embodiment of the present invention is described in further detail, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those skilled in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
As depicted in figs. 1 and 2, present embodiment proposes a kind of preferred metal powder injection molding sintering tool, and it includes jig body, and described jig body has the support platform for supporting workpiece 1 to be sintered, described jig body is provided with locating slot 2, is used for fixing workpiece 1 to be sintered.
In the present embodiment, above-mentioned jig body is preferably the profile of sintering pan 3, the profile of sintering pan 3 and workpiece 1 to be sintered and matches, and further, the profile of sintering pan 3 is rounded.Owing to the face shaping of sintering pan 3 is consistent with the profile of workpiece 1 to be sintered, workpiece 1 to be sintered shrinks according to reservation shape when high temperature sintering, sintering finished to metallic state time will not deform, be conducive to the dimensional accuracy of metal injection molded workpiece.
In order to facilitate stable support workpiece 1 to be sintered, the external diameter of sintering pan 3 is be more than or equal to the external diameter of workpiece 1 to be sintered, it is ensured that workpiece 1 to be sintered is integrally placed on the support platform of sintering pan 3.
The locating slot 2 of present embodiment is preferably the open slot being opened in sintering pan 3 outer rim, and workpiece 1 to be sintered is provided with the boss (not shown in Fig. 2) matched with open slot.In the present embodiment, sintering pan 3 is provided with an open slot, by this open slot with bottom workpiece 1 to be sintered arrange coordinating of boss realize fixedlying positioning of workpiece 1 to be sintered.Certainly, open slot is not limited to one, and open slot can also have two, and two open slots are symmetricly set on sintering pan 3, makes the fixing more solid and reliable of workpiece 1 to be sintered.In like manner, when open slot more than two, multiple open slots can be distributed on the outer rim of sintering pan 3, the stability that same enhancing workpiece to be sintered 1 is fixing.
In order to save rapidoprint, reducing processing cost, above-mentioned sintering pan 3 is designed as hollow structure, say, that sintering pan 3 is the closing shell structure of inner hollow.
In the present embodiment, the material of jig body is aluminium oxide or zirconium oxide.Owing to aluminium oxide or zirconia material have intensity height, hardness is big, and the advantage such as high tenacity, high-wearing feature, high temperature resistant and corrosion resistance, therefore, the sintering tool adopting them to make has resistance to elevated temperatures when metal injection molded sintering.
The detailed process that workpiece 1 to be sintered is sintered by sintering tool is as follows: be placed on by the workpiece to be sintered 1 extracted on sintering tool one by one, each tool is put a workpiece 1 to be sintered, the sintering tool putting workpiece 1 to be sintered is placed directly on graphite cake, namely can put into graphite vacuum furnace and complete sintering.
Present configuration is simple, it is possible to effectively prevent the sintering warpage of metal powder injection molding product so that goods of furniture for display rather than for use work becomes simple, improves production efficiency, and depositing of product is also more in good order, advantageously in field management.
To describe the know-why of the present invention in conjunction with specific embodiments.These descriptions are intended merely to explanation principles of the invention, and can not be construed to limiting the scope of the invention by any way.Based on explanation herein, those skilled in the art need not pay performing creative labour can associate other detailed description of the invention of the present invention, and these modes fall within protection scope of the present invention.
