[0016] The invention relates to a production method of an aluminum profile frame for a high-speed rail sound barrier. The aluminum bar is used as the main material, and the mold design, batching, smelting, extrusion, discharging, artificial aging, powder spraying and assembly molding are carried out. Aluminum profile frame, the frame is surrounded by aluminum alloy frame 3, sawed into a 45° angle, A is connected with angle code 6; B is connected with angle iron 5; the middle of the component is an acrylic plate 1, in the middle of the aluminum alloy frame 3. Element ethylene propylene rubber 4; The outer frame at C is connected with a spring sheet 8 to increase the strength.
[0017] The production method of the aluminum alloy frame includes the following steps:
[0018] 1. Mold design: the size of the mold is 280*185, such a large size can increase the strength of the mold and is not easy to collapse; the design adopts 7 shunt holes, 6 bridge positions, and a double hole in t...
