Abstract

The invention relates to a hot extrusion mold for a small-sized aluminum alloy round tube. The hot extrusion mold comprises an upper mold and a lower mold, wherein a lower mold core is arranged in an inner cavity of the lower mold. The hot extrusion mold is characterized in that a through hole is formed in the center of the upper mold, an upper mold core is inlaid in the through hole, a pressure relief ball is arranged at one end of the upper mold core, and a core head working tape is arranged at the other end of the upper mold core and is located in the inner cavity of the lower mold core; the outer end face of the pressure relief ball is a spherical surface, the inner end face of the pressure relief ball is a plane matched with the end face of the upper mold. According to the hot extrusion mold, the stable production aiming at the small-sized and high-precision round tube can be guaranteed, and particularly the abnormal problems that the core head working tape of the upper mold core is easy to wear, the utilization stability of the mold is poor due to pressure fluctuation, and the like are solved.

Description

technical field [0001] The invention relates to a hot extrusion die, in particular to a high-precision small-size (outer diameter less than 8mm) aluminum alloy round tube hot extrusion die. Background technique [0002] High-precision small-size aluminum alloy finished round tubes are currently widely used in industries such as automobiles, electric power, and home appliances. However, the mass production of this type of aluminum alloy tube by hot extrusion followed by cold drawing or direct extrusion is currently a method with high production efficiency and good quality stability. However, extrusion and cold drawing must increase the process, which increases the cost and process disturbance factors. It is the best choice for mass production to directly extrude the finished product on the basis of sufficiently stable mold design. Existing molds are solid mold steel materials (such as figure 1 , figure 2 As shown, 1a is the upper mold, 2a is the lower mold, 3a is the low...
