Several aspects that must be considered for industrial aluminum profile extrusion molds

　　From the perspective of theoretical knowledge of industrial aluminum profile extrusion molds, theoretical knowledge refers to: such as the extrusion ratio calculation formula and strength verification formula of aluminum profile extrusion diversion molds; Empirical knowledge refers to: for example, the bridge width value is 20-30, the welding chamber depth value is 15-45 (generally for small machines such as 800-1000T, the value is 15), for example, the welding chamber of a 10000T extrusion machine can reach 45 or even 50, and so on;

　　Normative knowledge refers to: such as the external diameter of the mold, the thickness of the upper and lower molds, etc; Inspirational knowledge refers to the selection of a set of empirical parameters for trial design, based on a previously designed, qualified mold mature design scheme similar to the current design, and gradually adjusting each parameter to obtain a reasonable design scheme.

　　The design of aluminum profile pressing molds is often based on experience accumulation. There is currently no complete and systematic feasible design theory available. The following application of inspirational knowledge will illustrate the importance of experience in the design process of industrial aluminum profile extrusion molds. For a parameter that needs to be determined during the design process, if there is no direct calculation formula and only a verification formula, it is only the main factor that affects the range of parameter values. People record the empirical values and conditions of this parameter in the previous design, and when similar situations are encountered again, the value of the parameter can serve as inspiration and guidance. For example, when determining process parameters, the number of die holes, extruder tonnage, extrusion diameter, extrusion ratio, and ingot size of a certain cross-section design are mutually influencing and interrelated parameters. In actual production, there is no independent calculation formula for a certain parameter, and often a group of parameters are selected based on experience and determined through exploratory methods.

　　When designing a new aluminum profile from the perspective of the industrial aluminum profile extrusion mold design scheme, similar profiles can be first searched for, and a set of parameters can be used as the initial parameters for trial design. Then, the parameters can be gradually adjusted until they are reasonable.

　　The design of aluminum profile extrusion molds is different from general mechanical design. It is a process design that lies between mechanical design and pressure processing. In addition to the principles that need to be followed in the design of ship machinery, it is also necessary to consider various process factors under hot extrusion conditions, which are determined by various factors, including factors considered by aluminum profile extrusion mold designers, mold manufacturers, and extrusion producers.
