Forming technology and mold of automobile aluminum alloy pedal

The invention discloses a forming technology and mold of an automobile aluminum alloy pedal. The technology comprises the following technological steps of (1) melting preparation, wherein an aluminum alloy ingot is placed in a melting furnace to be molten, alloy liquid is subjected to modification and refining treatment after melting, and alloy liquid degassing is carried out; (2) die-casting forming, wherein the mold is preheated for preparation, then mold assembly, pouring mold filling, casting solidification and mold opening for piece taking are carried out, a cinder ladle and a sprue are removed finally, and a pedal casting blank is obtained; (3) natural cooling, wherein after die-casting forming, the pedal casting blank is placed in the room temperature environment to be naturally cooled for 12 h-15 h; and (4) aging treatment, wherein a casting is placed in a heat treatment furnace for aging treatment, the work temperature ranges from 165 DEG C to 195 DEG C, and the heat preservation time ranges from 3 h
