Description

Technical Field

[0001] The utility model relates to the field of extrusion dies, in particular to a water-cooled and heat-dissipating extrusion die for aluminum profiles. Background Art

[0002] An extrusion die is a tool used to extrude materials such as plastic, rubber, metal, or ceramic into a specific shape under high pressure. During the extrusion process, the material is heated to a softened state and then extruded through the die's aperture to form a continuous, long product such as a pipe, profile, or wire. The design and manufacture of extrusion dies are crucial to product quality and production efficiency.

[0003] Aluminum extrusion dies are key tools used in the production of aluminum profiles. They extrude aluminum into specific cross-sectional shapes at high temperatures. When designing and manufacturing aluminum extrusion dies, factors such as the flow characteristics of the aluminum, cooling rate, and the strength and durability of the die must be considered. The die is typically made of carbide or special steel and precision-machined to ensure the profile's dimensional accuracy and surface quality. During the aluminum profile production process, die maintenance and replacement cycles are also significant factors affecting production efficiency and costs.

[0004] In the existing technology, many ordinary aluminum profile extrusion dies do not have heat dissipation function. When working for a long time, the high temperature generated by the extrusion die may cause workers to be burned due to improper operation, and may also cause damage to the materials to be processed.
