Embodiment

[0009] The aluminum alloy extrusion molding die of this embodiment includes a mold 1, a die pad 2 and a deflector 3, and the deflector 3 is provided with a stepped diversion hole 4, and the stepped diversion hole 4 is released from the mold. The farther the pad 2 is, the larger the opening is, and a circulating cooling water channel is arranged around the extruding barrel.

[0010] Preferably, the number of steps of the stepped diversion holes 4 is 2-5.

Abstract

The invention relates to an aluminum alloy extrusion molding die which comprises a die body, a die cushion and a flow guide plate. The flow guide plate is provided with a stepped flow guide hole. The opening of the stepped flow guide hole is gradually increased in the direction away from the die cushion. A circulation cooling water channel is arranged on the periphery of an extrusion barrel. Coarse grains are prevented from appearing when aluminum alloy bars are extruded and manufactured by means of the die.

Description

technical field [0001] The invention relates to an aluminum alloy extrusion molding die, 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....
