Preparation method of high-performance die-casting aluminum alloy material for automobile structural part

Abstract

The invention relates to the technical field of die-casting aluminum alloy materials, and discloses a preparation method of a high-performance die-casting aluminum alloy material for an automobile structural part, and a die-casting main body is included. According to the preparation method of the high-performance die-casting aluminum alloy material for the automobile structural part, the die-casting main body, an auxiliary plate, a supplementing opening, a water inlet, a baffle, a groove, a shell, a non-slip mat, an extension column, a die groove and a butt-joint hole are matched and connected for use, so that the problems that when the die-casting aluminum alloy material of equipment is used for production, the strength and the ductility are relatively low, the performance requirement of the automobile structural part cannot be met, the performance of an automobile die after injection molding is not stable enough are solved, during operation, alloy liquid is injected through internal die casting, an internal valve needle conducts strong extrusion, an external heating valve is matched, so that the internal liquid is more stable, and the mechanical performance of die-casting alloy is improved; and therefore, the vacuum degree in a pressure chamber and a die cavity is reduced, the lightness and extensibility of the die are improved, and the practicability is higher.

Description

technical field [0001] The invention relates to the technical field of die-casting aluminum alloy materials, in particular to a method for preparing high-performance die-casting aluminum alloy materials for automotive structural parts. Background technique [0002] Die-casting mold is a tool for casting metal parts. It is a tool that completes the die-casting process on a special die-casting die forging machine. The basic process of die-casting is that the molten metal is first filled into the cavity of the mold by low-speed or high-speed casting. The mold has a movable cavity surface, which is forged under pressure during the cooling process of the molten metal, which not only eliminates the shrinkage cavity and porosity defects of the blank, but also makes the internal structure of the blank reach the broken grains of the forged state, and the comprehensive mechanical properties of the blank are improved. Significant improvement. Die-casting materials, die-casting machines...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a method for preparing a high-performance die-casting aluminum alloy material for automotive structural parts, which can increase the internal compressive strength of the aluminum alloy material, increase the tensile strength of the surface and simultaneously improve the material strength. Extending, making the automobile mold made of aluminum alloy material more stable and other advantages, solves the problem that the strength and elongation of aluminum alloy material are relatively low during the production of die-casting aluminum alloy material, which cannot meet the performance requirements of automobile structural parts, resulting in the failure after injection molding The performance of the automobile mold is not stable enough, and the internal structure is not compact enough
