Judging from the current production of aluminum profiles, the application of aluminum extrusion dies is becoming more and more extensive and the role of supporting aluminum profile production is becoming more and more obvious. Based on the important role of aluminum extrusion dies, in the process of designing aluminum extrusion dies, improving its scientificity and rationality is of great significance to the design of aluminum extrusion dies.

Aluminum extrusion die design should reasonably set extrusion parameters

In the design of aluminum extrusion die, the setting of extrusion parameters is not only a key factor related to the design effect of aluminum extrusion die, but also the key to determine the overall quality of aluminum extrusion die design. Judging from the current aluminum extrusion die design, the extrusion parameters mainly include the diameter of the extrusion barrel, the extrusion coefficient and the split ratio. In the setting of these parameters, ensuring the accuracy of extrusion parameters is the key to improving the scientific and reasonable design of aluminum extrusion die. 

Aluminum extrusion mold design should make good choice of mold material

Considering the importance of aluminum extrusion dies, and the need for aluminum extrusion dies to withstand greater pressure during processing, the choice of mold materials is critical in the design of aluminum extrusion dies. If the hardness of the mold material is large, the extrusion difficulty will increase during the processing of the aluminum extrusion mold, and the internal cracks of the mold will easily occur. If the material hardness of the aluminum extrusion mold is too low, problems such as excessive deformation will occur during the extrusion of the mold. 

Aluminum extrusion mold design should reasonably determine the specifications of the mold

In the design process of aluminum extrusion molds, reasonable determination of the mold specifications is an important part of mold design. In combination with the design experience of aluminum extrusion molds, in the determination of the mold specifications, it is necessary to carefully analyze the outer circle size of the profile, and at the same time, carefully analyze the distribution of the orifices and the strength requirements of the mold. The calculation process and calculation basis must be determined according to the design needs of the aluminum extrusion die. Therefore, the design of aluminum extrusion dies can only ensure that the design of the aluminum extrusion dies scientifically and reasonably meets the actual needs in order to improve the design effect of the aluminum extrusion dies only if the specifications of the dies are reasonably determined.

The design of aluminum extrusion die should be well arranged

The arrangement, size, and shape of the mold shunt holes are directly related to the balance of metal supply flow and the shape of the product. Because the shape of the profile has better symmetry, the shunt holes are arranged in a ten-hole structure arranged under the holes; the middle shunt holes are close to the center of the extrusion barrel, and the shunt holes at both ends are far from the extrusion center and are subject to the extrusion barrel the influence of wall friction force, therefore, the size of the feed area of each split hole needs to be adjusted.
