Abstract

The invention discloses a powder alloy pressing mold used for an output shaft. The powder alloy pressing mold comprises an upper mold body and a lower mold body, and further comprises a middle mold body arranged between the upper mold body and the lower mold body. A mold cavity of the middle mold body is filled with metal powder used for molding the output shaft. The upper mold body comprises an upper guide sleeve and a pressing rod, wherein a square end opening is formed in one end of the upper guide sleeve, the pressing rod is matched with a square through hole axially formed in the axis of the upper guide sleeve, and one end of the upper guide sleeve is matched with the upper end of the mold cavity of the middle mold body; the lower mold body comprises a lower guide sleeve and an ejector rod, wherein four long grooves are axially and evenly formed in the circumferential wall of an end opening in one end of the lower guide sleeve, the ejector rod is matched with a circular hole axially formed in the axis of the lower guide sleeve, and one end of the lower guide sleeve is matched with the lower end of the mold cavity of the middle mold body. As the upper mold body is matched with the lower mold body, complex structures at the two ends of the output shaft can be conveniently molded, the secondary machining trouble is saved, the powder alloy pressing mold brings convenience to one-time molding of the output shaft, and the machining accuracy and the production efficiency are high.

Description

technical field [0001] The invention relates to the technical field of powder metallurgy pressing molds, in particular to a powder metallurgy pressing mold used for output shafts. Background technique [0002] Due to the complex structure of the output shaft in the prior art, when the traditional processing method is used for processing, the processing is difficult and the parts are not processed accurately, thus greatly increasing the processing cost of the parts and the production efficiency is very low. Contents of the invention [0003] The object of the present invention is to provide a powder metallurgy pressing mold which is convenient for one-time molding of the output shaft and has high machining accuracy and production efficiency. [0004] For reaching this purpose, the present invention adopts following technical scheme: [0005] A powder metallurgy pressing mold for an output shaft, including an upper mold and a lower mold, and a middle mold arranged between t...
