(3) heating the forging die to 600 ℃ and preheating for 1-2 hours;
(4) smearing a high-temperature-resistant lubricant into the die;
(5) Forging and pressing by using a hydraulic transmission machine until the die is completely closed;
(6) Putting the forged and pressed aluminum-copper alloy obtained in the step (5) into a leaching chamber for leaching and cooling;
(7) And (4) polishing the aluminum-copper alloy leached in the step (6) by using a polishing machine, and finishing die forging after polishing.
