Adjustable Bracket Aluminum Profile Hot Extrusion Die

Abstract

The invention relates to a hot extrusion die, particularly to an aluminum profile hot extrusion die for an adjustable bracket, and belongs to the technical field of hot extrusion dies. The aluminum profile hot extrusion die comprises an upper die and a lower die which are connected in an overlapping manner in the up-down direction; an inner sunken bridge is arranged between every two adjacent inner flow guide holes in the up-down direction; an outer sunken bridge is arranged between every two adjacent outer flow guide holes; a welding chamber, a mold cavity and multistage discharge holes are arranged at the center of the lower die from the feed end face to the discharge end face; a plurality of convex stop bosses are arranged on the inner surface of the welding chamber along the edge of the mold cavity; and the central die core, the first side die core and the second side die core of the upper die extend into the mold cavity of the lower die. The aluminum profile hot extrusion die forthe adjustable bracket has the advantages as follows: the cantilever at the opening is prevented from deviation and collapse after extrusion, the dimensions can meet the use requirements, the extrusion production is stable, and the service life is long; besides, the direct pressure of the aluminum flow on the upper die is reduced through the inner and outer flow guide holes by adopting a hole enlarging method, and the material feeding at screw holes is ensured through the stop bosses reserved in the welding chamber of the lower die.

Description

technical field [0001] The invention relates to a hot extrusion die, in particular to an adjustable bracket aluminum profile hot extrusion die, which belongs to the technical field of hot extrusion dies. Background technique [0002] With the continuous development of society, the constant change of market demand, and the increasingly fierce market competition, a high-quality, high-standard adjustable bracket is particularly scarce in the market, which brings huge business opportunities to mold manufacturers. Many Manufacturers are taking action, but the products they make are difficult to meet the requirements of customers, and their own costs remain high, and molds are easily scrapped. [0003] As we all know, it is difficult to ensure the opening of the hot extrusion die of the adjustable bracket during extrusion, and the flatness requirements are also very high, especially its dimensional tolerance requirements are particularly strict. The key reason why the mold is scra...
