Description

Technical Field

[0002] In the production process of aluminum profiles, the extrusion die is one of the core tools, and the die pad, as an important component of the die, has a direct impact on product quality and production efficiency. Aluminum profile extrusion die pads with demoulding structures are widely used in the production of architectural aluminum, industrial aluminum, and high-end medical equipment. With the increasing demand for aluminum profiles in these fields, the performance requirements for die pads are also getting higher and higher. Therefore, this new type of die pad has broad market prospects and application potential.

[0003] Current aluminum extrusion die pads with a demolding mechanism first heat the aluminum extrusion die to an appropriate temperature (e.g., around 480 degrees Celsius). Then, an aluminum ingot is placed in the die's working zone for extrusion. During the extrusion process, an inert gas (e.g., nitrogen) is introduced into the die hole through air guide grooves on the die pad, creating a stable inert gas environment that isolates the high-temperature profile from oxygen. As the extrusion process progresses, the profile gradually emerges from the die. At this point, the demolding mechanism pushes or pulls the die pad, separating the aluminum profile from the die. During the demolding process, mechanical or hydraulic devices can cause stress concentration between the aluminum extrusion die and the extrusion die pad, leading to surface defects such as scratches or deformation.
