Beschreibung
Zusammenfassung:	The invention discloses a die-casting machining method for automobile parts, and belongs to the field of automobile part machining. Comprising the following steps that firstly, an aluminum alloy material is pretreated and then heated to be molten, and the temperature of the aluminum alloy material is kept at 650 DEG C; secondly, after a mold is preheated, the molten aluminum alloy material is injected from the bottom of the mold; wherein the pressure casting pressure is 70 Mpa, the pressure maintaining time is 15 s, the injection is divided into three stages, the injection speed of the first stage is 0.5 m/s, the injection time of the first stage is 0.2 s, the injection speed of the second stage is 3 m/s, the injection time of the second stage is 0.5 s, the injection speed of the third stage is 4 m/s, and the injection time of the third stage is 0.1 s; and thirdly, post-treatment is conducted on the parts obtained after die casting is completed. The method has the characteristics of improving the mechanical p
