The metal powder injection molding and sintering jig comprises a jig body, wherein the jig body comprises a base plate and a jig side wall which is in contact with the side wall of a workpiece to be sintered; two bulges are arranged on the inner surface of the side wall of the jig, and are respectively matched with two grooves formed in the side wall of the workpiece to be sintered. The sintering jig disclosed by the invention is provided with the jig side wall matched with the side wall of the workpiece to be sintered, to prevent breakage and bending deformation of the workpiece to be sintered; meanwhile, the bulges are arranged on the inner surface of the jig side wall, and are matched with the corresponding grooves of the workpiece to be sintered, so that effects of positioning and displacement prevention can be achieved; meanwhile, the matching between the bulges and the grooves make the owrkpiece to be sintered placed more accurately, and the workpiece sintering efficiency is improved.
Description
Technical field
The present invention relates to sintering technology 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 carries out compound pelletizing.Get rid of binding agent after molding, then defat base is sintered.But, product is before sintering, especially the most fragile after removing binding agent, especially to having erose blank, easily produces fracture, flexural deformation, displacement etc., thus causes scrapping of product.And blank quantity is more, sintering needs again fixing placing attitude, needs to expend a large amount of manpower and is the most correctly put by product, and production efficiency is relatively low.
Summary of the invention
It is an object of the invention to propose a kind of metal powder injection molding sintering tool, it is possible to prevent the fracture of workpiece to be sintered, flexural deformation, displacement, and production efficiency can be improved.
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 includes that the tool sidewall that chassis and the sidewall with workpiece to be sintered contact with each other, the inner surface of described tool sidewall are provided with two projections, respectively with two fit depressions on the sidewall of workpiece to be sintered.
As a kind of preferred version of above-mentioned metal powder injection molding sintering tool, described chassis is provided with location bar, and described location bar is located in the through hole on described workpiece to be sintered.
As a kind of preferred version of above-mentioned metal powder injection molding sintering tool, the center on chassis is provided with central recess, and the projection for the bottom with described workpiece to be sintered coordinates.
As a kind of preferred version of above-mentioned metal powder injection molding sintering tool, two projections are centrosymmetric relative to the center on chassis.
As a kind of preferred version of above-mentioned metal powder injection molding sintering tool, described projection is rectangular preiection.
As a kind of preferred version of above-mentioned metal powder injection molding sintering tool, described central recess is cylinder shape groove.
As a kind of preferred version of above-mentioned metal powder injection molding sintering tool, described sintering tool also includes that, between two vertical blocks that ceramic block, described ceramic block are located at workpiece to be sintered, the both sides of ceramic block fit with two vertical blocks respectively.
Beneficial effects of the present invention:
The metal powder injection molding sintering tool that the present invention proposes, the tool sidewall that sidewall with workpiece to be sintered cooperates is set, it is prevented from the fracture of workpiece to be sintered, flexural deformation, it is provided with projection in tool side wall inner surfaces simultaneously, the corresponding recesses making protruding and to be sintered workpiece coordinates, can play location and prevent the effect of displacement, projection can also make putting of workpiece to be sintered more accurate with coordinating of groove simultaneously, improves workpiece sintering efficiency.
