The invention discloses an aluminum profile small circular pipe hot squeezing die capable of producing four products simultaneously. The aluminum profile small circular pipe hot squeezing die comprises an upper die body and a lower die body. Four flow distribution bridges are arranged on the upper die body, flow distribution holes are formed between the flow distribution bridges, and small work heads are arranged on the flow distribution bridges. A weld joint chamber is formed in the lower die body, die holes are formed in the weld joint chamber and correspond to the small work heads in one-to-one mode, and outlet cutters and discharging outlets are arranged/formed on/in the bottoms of the die holes in sequence. According to the aluminum profile small circular pipe hot squeezing die, the structure is stable, through the four-outlet-in-one-die mode, the squeezing ratio of the die is within a reasonable range, squeezing force is reduced, the service life of the die is prolonged, the production efficiency is improved, and thus the cost is reduced.
