Abstract

The invention discloses a butterfly-shaped extrusion mold for producing flat-width thin-wall multi-cavity aluminum profiles. A butterfly-shaped upper mold is arranged as a multi-stage arch-shaped arcsurface divergent bridge, the radius of the arch-shaped divergent bridge is 150-200 mm, the arch-shaped divergent bridge sinks by 10-20mm along the butterfly-shaped upper mold end surface, and a maindivergent bridge at the center position continues to sink by 10-15mm so as to reduce stress of the mold in the extrusion process; and a butterfly-shaped lower mold is designed to be provided with two-stage welding chambers with a butterfly-shaped contour, the height of a first-stage welding chamber and the height of a second-stage welding chamber are 15-25 mm and 5-10mm. According to the butterfly-shaped extrusion mold, a stop block can be additionally arranged in the second-stage welding chamber, so that the flow rate of a material can be adjusted, the welding quality can be improved, the flat-width thin-wall multi-cavity aluminum profiles with geometric shape and good welding quality can be produced, so that the service life of the extrusion mold is effectively prolonged, and the extrusion production energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of aluminum profile production, in particular to a butterfly extrusion die used for the production of flat, wide, thin-walled and multi-cavity aluminum profiles. Background technique [0002] As the application fields of extruded aluminum profiles become wider and wider, aluminum profiles are developing in the direction of large, flat and wide, thin-walled, multi-cavity, and high-precision. For the flat, wide and thin-walled multi-cavity aluminum profiles, traditional split molds are currently used for production. However, due to the large difference in extrusion width-to-expansion ratio, profile width-to-thickness ratio, and wall thickness, it is difficult to control the volume distribution of the material during the pre-forming process in the mold cavity during the extrusion process, and the unevenness of extrusion deformation is very serious, which can easily lead to twisting , waves, poor welding, exces...
