Stable extrusion die for aluminum profile of automobile sunroof guide rail

Abstract

The invention relates to a stable extrusion die for an aluminum profile of an automobile sunroof guide rail. The stable extrusion die comprises a flow guiding die body, wherein a surface die body is connected with one end of the flow guiding die body; a plurality of first flow guiding holes are formed in the flow guiding die body; meanwhile, a plurality of fixing holes are formed in the flow guiding die body; a profiling-welding chamber is arranged at one end of the surface die body; a second flow guiding hole is formed in the surface die body; a notch is arranged at the feeding end of the surface die body; and a processing head is fixed in the profiling-welding chamber. By adoption of the stable extrusion die for the aluminum profile of the automobile sunroof guide rail, the size stability of sunroof profiles during the extrusion process can be effectively guaranteed; the elastic deformation of the stable extrusion die can be dramatically reduced; the finished product ratio of the sunroof profiles with strict requirements for the dimensional tolerance during the extrusion production can be improved by 20% or higher; the aluminum bar input as a raw material can be reduced; the waste of personnel working hours for reshaping after extrusion can be reduced; and the production time can be saved.

Description

technical field [0001] The invention relates to the technical field of automobile molds, in particular to a stable extrusion mold for aluminum profiles of automobile sunroof guide rails. Background technique [0002] Automobile sunroof guide rails are more and more widely used in automobiles. The aluminum profiles of the guide rails are required to ensure the smooth opening and closing of the sunroof, reduce the noise during the opening and closing process, and ensure the tightness when closing, so the tolerance requirements for dimensions are particularly strict. [0003] At present, the dimensional stability of the automotive sunroof profiles in the market is poor during the extrusion process. At the same time, the mold is prone to elastic changes, which makes the shape errors of the automotive sunroof profiles after being extruded. The automotive sunroof profiles with errors need to be manually processed later Trimming again will increase the production time and also incr...
