[0002] Metal extrusion molding die is a tool widely used in the metal processing industry. It is used to extrude metal blocks heated to a plastic state into profiles of specific shapes through a die. This technology is applicable to a variety of metals, including aluminum, copper, steel, etc. It is an important process for producing complex cross-sectional shapes such as pipes, rods, rails, etc. Metal extrusion molding can improve the mechanical strength of the material, improve the microstructure, and achieve continuous production of high-precision and complex shapes. It is widely used in construction, transportation, aerospace and other fields.

[0003] Traditional metal extrusion dies have several significant disadvantages. The first is the durability of the die. Since the die needs to withstand extremely high pressure and temperature during the extrusion process, the die wears relatively quickly, which directly affects the continuity of production and the quality of the product. Secondly, the cooling and heating process of the die is often not efficient enough, which will lead to unstable performance of metal materials and reduce the yield rate. In addition, the die replacement and adjustment process is complicated and time-consuming, which limits the flexibility and response speed of the production line. Especially when it is necessary to produce a variety of profiles, frequent die replacement significantly increases downtime and production costs. Utility Model Content
