When the left side mold and the right side mold are in a mold closing state, the demolding grooves formed in the bottoms of the left side mold and the right side mold directly face the demolding holes formed in the top of the lower mold platform; the extrusion forming device is provided with the demolding structure and the water cooling structure, the demolding and cooling effects are good, and the forming quality of an aluminum alloy workpiece can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of production and processing of aluminum alloy parts, in particular to an extrusion molding device for aluminum alloy workpieces. Background technique [0002] Aluminum alloy is an alloy with aluminum as the base material and a certain amount of other alloying chemical elements added. It is one of the light metal materials. In addition to the general characteristics of aluminum, aluminum alloys also have specific characteristics of some alloys due to the different types and quantities of alloying chemical elements added. Aluminum alloys can be used as structural materials and are widely used in aerospace, aviation, transportation, construction, electromechanical and other fields. [0003] During the production and processing of aluminum alloy workpieces, aluminum alloy raw materials are usually hot-extruded, so that workpieces of different shapes and structures can be obtained according to the shape and str...

AI Technical Summary

Problems solved by technology

[0003] During the production and processing of aluminum alloy workpieces, aluminum alloy raw materials are usually hot-extruded, so that workpieces of different shapes and structures can be obtained according to the shape and structure of the mold. However, in the prior art, the extrusion of aluminum alloy workpieces The molding process has the following problems: First, it is difficult to demould the finished product, and the demoulding structure of the existing aluminum alloy extrusion molding device is generally arranged inside the bottom mold, and the setting of the demoulding structure makes the bottom mold non-integral. During the extrusion process of the mold, the demoulding structure will be displaced under pressure, which will affect the quality of the lower surface of the finished aluminum alloy workpiece; secondly, after the aluminum alloy is extruded, the extrusion stress between the finished product and the side of the mold is relatively large. The mold structure is difficult to achieve demoulding, and forced demoulding will affect the quality of the side surface of the finished workpiece; in addition, the uneven cooling of the finished workpiece after extrusion molding of aluminum alloy will easily lead to stress deformation and other problems, which will affect the quality of the finished aluminum alloy workpiece
