Abstract

The invention relates to an aluminum profile extrusion die for a frame and belongs to the technical field of dies. The aluminum profile extrusion die for the frame comprises an upper die and a lower die, wherein the upper die and the lower die are connected through a positioning pin and a fastening screw; a die core is arranged in the middle of the upper die; seven dividing holes are formed aroundthe die core; three dividing holes on the upper side and four dividing holes on the lower sides are arranged adaptive to an aluminum profile structure; dividing bridges are arranged among the dividing holes; the dividing bridges are designed as tips, the inlet sections of which form included angles of 40 degrees; a welding chamber, a cavity and a discharge port are formed in the lower die; a primary welding chamber and a secondary welding chamber are arranged in the welding chamber; and a primary empty cutter and a secondary empty cutter are arranged at the discharge port. The welding effectof a metal flowing through the dividing holes is good, the outlet speed of the profile is uniform, and particles adsorbed to the surface of the aluminum profile are reduced.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to an aluminum profile extrusion mold for a vehicle frame. Background technique [0002] During the extrusion process of aluminum profiles, adsorption particles are prone to appear on the surface of aluminum profiles, which are difficult to remove in the production process of electrophoresis and spraying profiles, which will affect the appearance of profiles. The design and manufacture of aluminum profile extrusion dies have a very important influence on the generation of adsorbed particles. Contents of the invention [0003] Aiming at the defects and deficiencies in the prior art, the present invention proposes an aluminum profile extrusion die for a vehicle frame. The welding effect is good after the metal flows through the diversion hole, and the exit speed of the profile is uniform, reducing the surface area of ​​the aluminum profile. of adsorbed particles. [0004] The techni...
