Forging die for aluminum alloy central wing rear beam frame

The utility model discloses a forging die for an aluminum alloy central wing rear beam frame. The die comprises an upper die and a lower die, a forging impression is formed between the upper die and the lower die, the lower end face of the upper die is of a plane structure, a forming boss is arranged in the middle of the lower die, a decompression groove is formed in one end of the forming boss, and a structural recess and a structural protrusion which are matched with a rear beam frame structure are arranged in the forming boss. The structural recesses and the structural protrusions are staggered to form rear beam frame weight reduction grooves, overflow grooves are distributed all over the periphery of the forming boss, and overflow channels are formed in the peripheries of the overflow grooves. Compared with a traditional forging die for the central wing rear beam frame, the forging die for the central wing rear beam frame is convenient to operate and small in subsequent machining amount, improves assembly
