The invention discloses a flaring mold for two ends of a pipe. The flaring mold comprises an upper mold plate and a lower mold plate. A guide rod, a tapered wedge and an upper convex mold are fixedly connected to the lower surface of the upper mold plate in sequence from left to right. A lower convex mold is symmetrically arranged at the position, corresponding to the upper convex mold, of the lower mold plate. A left movable clamp plate and a right movable clamp plate are arranged on the two sides of the lower convex mold correspondingly. The bottom of the left movable clamp plate and the bottom of the right movable clamp plate are both fixedly connected to the upper surface of the lower mold plate. The lower side of the side face, far away from the lower convex mold, of the left movable clamp plate is fixedly connected with one end of a first spring. According to the flaring mold, through the arrangement of the tapered wedge, when the tapered wedge is pressed, the left movable clamp plate moves rightwards, and the pipe is clamped; through the arrangement of a guide pipe and the guide rod, position shift cannot happen when the upper mold plate is pressed; through the arrangement of the upper convex mold, the lower convex mold, the left movable clamp plate and the right movable clamp plate, the effect of flaring the two ends of the pipe is achieved; and the two ends of the pipe are flared by the upper convex mold and the lower convex mold at the same time, and during use, greater convenience is achieved, and more time is saved.
