Problems solved by technology
[0002] Aluminum profile extrusion dies generally include an upper mold and a lower mold. The upper mold is equipped with a fixed core, and the lower mold is equipped with a forming hole. When the hot-melt material is extruded through the mold, the inside of the core and the forming hole will be Continuous wear, as the production continues, this wear will continue to accumulate, and eventually the entire set of molds will be scrapped and must be replaced with new molds, which will greatly shorten the service life of the mold and increase the operating cost of the enterprise

Description
technical field [0001] The invention relates to the technical field of extrusion dies for aluminum profiles, in particular to an extrusion die for aluminum alloy door and window profiles. Background technique [0002] Aluminum profile extrusion dies generally include an upper mold and a lower mold. The upper mold is equipped with a fixed core, and the lower mold is equipped with a forming hole. When the hot-melt material is extruded through the mold, the inside of the core and the forming hole will be Continuous wear, as production continues, this wear will continue to accumulate, and eventually the entire set of molds will be scrapped and must be replaced with new molds, which will greatly shorten the service life of the mold and increase the operating cost of the enterprise. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems existing in the existing extrusion dies for aluminum alloy doors and windows, and to p...
