Abstract

The invention discloses a metal powder injection-molding sintering jig, and relates to the technical field of sintering jigs. The metal powder injection-molding sintering jig comprises a jig body. The jig body comprises a supporting platform used for supporting a to-be-sintered workpiece. A positioning groove is formed in the jig body and used for fixing the to-be-sintered workpiece. The metal powder injection-molding sintering jig is simple in structure and capable of effectively preventing sintering deformation of a metal powder injection-molded product, the workpiece placement work can be easy, the production efficiency is improved, product storage can be neater, and field management is better facilitated.

Description

technical field [0001] The invention relates to the technical field of sintering fixtures, in particular to a metal powder injection molding sintering fixture. Background technique [0002] Metal powder injection molding technology is a new manufacturing process technology that combines powder metallurgy and plastic molding technology. It is required to first mix the selected powder with a binder, and then granulate the mixture before injection molding. shape. After molding, remove the binder, and then sinter the degreased body. However, the product is very fragile before sintering, especially after the binder is removed, especially for irregularly shaped blanks, which are prone to fracture, bending, displacement and other deformations, resulting in scrapping of the product; and when the blank When the quantity is large, the sintering needs to be placed in a fixed posture, which requires a lot of manpower to correctly place the products one by one, and the production effic...
