Abstract

The invention relates to an aluminum alloy rod mold which comprises a mold body, a cushion and a guide plate. The aluminum alloy rod mold is characterized in that a stepped guide hole is formed in the guide plate, and an opening of the stepped guide hole is larger when the stepped guide hole is farther away from the cushion. Coarse-grains can be avoided when aluminum alloy rods are extruded and manufactured.

Description

technical field [0001] The invention relates to an aluminum alloy bar mold, which belongs to the technical field of mechanical manufacturing and processing. Background technique [0002] The traditional production method of aluminum alloy rods adopts the central extrusion method of positive extrusion, that is, the hole is in the center of the die and coincides with the center of the extrusion barrel. In this way, the mold is easy to manufacture, the degree of extrusion deformation is small, and the extrusion force is low. The disadvantage is that the grain size of the profile is large, and coarse grains are prone to occur, and the obtained mechanical properties and electrical conductivity are low. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the disadvantages of the above-mentioned technologies, and to provide a mold that avoids coarse grains when extruding and manufacturing aluminum alloy rods. [0004] In...
