Discuss the relevant knowledge points of aluminum extrusion molds

　　Aluminum extrusion molds are key tools used for aluminum profile extrusion forming, and their design and manufacturing directly affect product quality and production efficiency. The following are the main contents and related knowledge points of aluminum extrusion molds:

　　1. Mold structure

　　Aluminum extrusion molds typically consist of the following parts:

　　Die: The core part that determines the cross-sectional shape of a profile.

　　Housing: Fixing the mold core and providing support.

　　Port Hole: Guide the flow of aluminum material.

　　Welding Chamber: Ensure that the aluminum material is re bonded after diversion.

　　Bearing: Control the size and surface quality of profiles.

　　2. Mold materials

　　Mold materials need to have high strength, heat resistance, and wear resistance. Common materials include:

　　H13 steel: widely used, with good heat resistance and wear resistance.

　　SKD61: Japanese standard, performance similar to H13.

　　Other alloy steels: such as 2344, 1.2344, etc.

　　3. Design points

　　Diversion hole design: Ensure uniform flow of aluminum material.

　　Work belt length: affects profile size and surface quality.

　　Mold strength: It needs to withstand high pressure and high temperature.

　　Cooling system: Some molds are equipped with cooling channels to extend their lifespan.

　　4. Manufacturing process

　　Processing: CNC machining, electrical discharge machining (EDM), etc.

　　Heat treatment: Improve hardness and wear resistance.

　　Surface treatment: such as nitriding treatment to enhance surface properties.

　　5. Common problems

　　Mold cracking: caused by design or material issues.

　　Dimensional deviation of profiles: caused by working belt design or wear.

　　Surface defects: caused by rough mold surface or insufficient lubrication.

　　6. Maintenance and upkeep

　　Regular inspection: promptly repair wear or damage.

　　Cleaning: prevent the accumulation of aluminum shavings from affecting quality.

　　Lubrication: Reduce friction and extend mold life.

　　7. Application Fields

　　Aluminum extrusion molds are widely used in industries such as construction, transportation, and electronics to produce profiles for doors, windows, tracks, radiators, and more.

　　8. Development Trends

　　Intelligent design: optimize design with the help of CAD/CAE technology.

　　Application of new materials: Improve mold performance.

　　Additive Manufacturing: 3D printing technology is used for complex mold manufacturing.

　　summary

　　The design and manufacturing of aluminum extrusion molds are crucial for the production of aluminum profiles. Reasonable structural design, material selection, and manufacturing processes can significantly improve product quality and production efficiency.
