A cable sheath extrusion die relates to the field of extrusion dies and comprises a die sleeve and a reducing sleeve. One end of the die sleeve is provided with a limiting clamping table, and the other end is a first connecting end; the die sleeve is provided with a feeding cavity and a sizing cavity; the inner diameter of the feeding cavity is gradually reduced from the rear end of the feeding cavity to the front end of the feeding cavity; the sizing cavity is a cylindrical groove; one end of the reducing sleeve is a mounting end, and the other end is a second connecting end; the diameter-changing sleeve is provided with a first mounting groove, a transition cavity and a diameter-changing cavity; the inner diameter of the transition cavity is gradually reduced from the rear end of the transition cavity to the front end of the transition cavity; the diameter-changing cavity is a cylindrical groove, and the inner diameter of the diameter-changing cavity is smaller than that of the sizing cavity; the diameter-c
