The utility model relates to a novel 160 double-layer extruder mold core. The problem that the work difficulty is high, the work efficiency is reduced and the mold core structure can cause sheath thickness to be eccentric in the cable manufacturing process in the prior art can be well solved. The key points of the technical scheme are as follows: the novel 160 double-layer extruder mold core comprises a mold core cone and a mold core bottom, the mold core cone is integrally frustum-shaped, the diameter of the top opening of the mold core cone is smaller than that of the bottom opening of the mold core cone, the lower end of the mold core cone and the upper end of the mold core bottom are fixedly connected, the outer side face of the mold core bottom is provided with threads of which the height is smaller than that of the mold core bottom, the diameter of the upper surface of the mold core bottom is larger than the outer diameter of the bottom of the mold core cone, the bottom of the outer side wall of the mold core cone is uniformly provided with a plurality of assembly and disassembly planes which are integrally rectangular, the upper sides of the assembly and disassembly planes are upwardly convex arc sides, and any two adjacent assembly and disassembly planes are connected. By adopting the novel 160 double-layer extruder mold core, the work efficiency can be improved.
