Abstract

Improvements in devices for the molding of helical toothed wheels by means of powder compression, of the type that comprise at least one fixed die that has the profile equal to that of the wheel to be molded, at least one movable punch that has a suitable end to join with said matrix to compress the powder, and guide means that serve to move said end with a helical movement of the same step as said profile, characterized in that said guide means are made up of a tap directly connected to the end of said punch.
