The utility model relates to a mold core for a rotating pipe and a forming mold. The mold core for the rotating pipe comprises a multi-stage core body, and the radial size of the multi-stage core body is increased step by step in the charging direction. According to the multi-stage core body, the formed rotating pipe can be provided with multiple stages of pipe cavities with different diameters, so that the corner position is formed, and the corner position can provide support for sintering or forging after the rotating pipe is pressed and formed. The radial size of the multi-stage core body is gradually increased in the loading direction, so that the multi-stage core body can form a forward step structure, extrusion of the core body on a blank pressed by a forming raw material is reduced, the overall uniformity of the blank is higher, the quality of a rotating pipe is improved, compression deformation of a corner position can be reduced, and the qualified rate of pressed green bodies is increased. 本申请涉及一种旋转管
