Skylight guide rail forming die

Abstract

The invention discloses a skylight guide rail forming die. The skylight guide rail forming die comprises an extrusion device and a die assembly, wherein the die assembly is fixed to one end of the extrusion device, and the extrusion device is composed of an extrusion cylinder, an extrusion gasket and an extrusion shaft. The extrusion gasket is located in the extrusion cylinder, the extrusion gasket is slidably connected with the inner wall of the extrusion cylinder, and one end of the extrusion shaft is fixed to the extrusion gasket. A semi-solid aluminum alloy containing cavity is formed in the end, away from the extrusion shaft, of the extrusion cylinder and the extrusion gasket. According to the skylight guide rail forming die, a die seat is fixed to one end of the extrusion device, a track groove is formed in the die seat, and a die is movably mounted in the die seat through a die insertion plate; when another type of guide rail is machined, a pressing device is only required to bepressed downwards, a clamping block is pressed into a clamping groove by a pressing column, the die is rotated, so that the die is separated from the die seat; and different dies are replaced, fixingand disassembly are more convenient than a traditional bolt, the die changing time is shortened, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of skylight guide rails, in particular to a molding die for skylight guide rails. Background technique [0002] Skylight guide rails are generally formed by liquid die forging extrusion. Liquid die forging is also called squeeze casting, continuous casting and continuous forging. It is a new metal forming process that has casting characteristics and is similar to die forging. The molten metal to be cast is directly poured into the cavity coated with lubricant, and the mechanical static pressure is continuously applied, and the solidified hard shell is plastically deformed by using the metal casting solidification and forging technology to make the metal crystallize under pressure Solidify and forcibly eliminate the shrinkage cavity and shrinkage caused by solidification shrinkage to obtain liquid die forging parts without casting defects. [0003] At present, the sunroof guide rail is produced by the liquid...

AI Technical Summary

Problems solved by technology

[0003] At present, the sunroof guide rail is produced by the liquid die forging equipment on the market, but due to the complex shape of the sunroof guide rail, the mold on the equipment needs to be replaced when processing another type of guide rail, but the traditional mold is fixed by bolts, which is inconvenient to replace , the long replacement time leads to reduced production efficiency and affects the benefits of the enterprise. Therefore, we propose a sunroof guide rail forming mold
