The utility model provides a pressing die capable of rapidly replacing inserts, and belongs to the technical field of die manufacturing. The pressing die comprises an upper mounting plate, an upper die body, a lower die body, a lower mounting plate, a top plate and vertical plates, the upper die body is fixed to the upper mounting plate, the lower die body is fixed to the lower mounting plate through the vertical plates on the two sides, the top plate is located between the two vertical plates, a die cavity is formed in the lower die body, an embedding groove is formed in the bottom in the die cavity, the insert is embedded in the embedding groove, and a first vertical through hole is formed in the die cavity. A vertical second through hole is formed in the caulking groove, a first ejector rod is arranged in the first through hole in a penetrating mode, the lower end of the first ejector rod is fixed to the ejector plate, a second ejector rod is arranged in the second through hole in a penetrating mode, the upper end of the second ejector rod is fixed to the insert, and the lower end of the second ejector rod is suspended. The insert replacement speed is high, after the insert is ejected out through the second ejector rod, the insert and the second ejector rod are directly pulled out of the mold cavity, the insert and the second ejector rod are separated, the second ejector rod is connected with the insert needing to be used, then the insert is inserted into the caulking groove to be pressed, and rapid replacement is completed.
