Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a lightweight aluminum alloy extrusion mold. Background Technology

[0002] Aluminum alloy extrusion dies are key tools used to extrude aluminum alloy billets heated to a plastic state through a high-pressure extrusion forming cavity to obtain profiles with specific cross-sectional shapes.

[0003] Traditional extrusion dies have high density, which increases equipment energy consumption and makes them difficult to replace quickly. They also have poor heat dissipation, causing heat to accumulate during high-temperature extrusion, which can easily lead to die deformation or scratches on the inner wall. In addition, the surface smoothness is insufficient, which affects the ejection rate and delays the process. Long-term high-pressure friction causes the die to wear out quickly, resulting in high maintenance costs. Furthermore, existing extrusion dies do not have limit mechanisms, which cause vibration and insufficient stability. Utility Model Content
