The invention discloses a die with a floating pressure compensation mechanism. The die comprises an upper die, a lower die and a female die, wherein the lower die is fixed below the female die; the upper die comprises an upper-die main body and a central upper-die rod; a third upper punch, a second upper punch and a first upper punch are arranged on two outer sides of the upper-die main body from top to bottom in sequence; the central upper-die rod penetrates the upper-die main body; the lower die comprises a lower-die main body and a central lower-die rod; the central lower-die rod penetrates the lower-die main body, and the central lower-die rod and the central upper-die rod are used cooperatively; the central lower-die rod as well as the central upper-die rod adopts a hollow structure; a first lower punch, a second lower punch and a third punch are arranged on two outer sides of the lower-die main body from top to bottom in sequence; and a floating cylinder is arranged at the bottom of the lower-die main body. Through a slight change in a die carrier, the die is simple to use and has high universality, the requirement and cost of the die are reduced, the stability of products is guaranteed, and the die has high applicability.
