The invention relates to the technical field of forming tools for metal drawing, and in particular relates to a wire-drawing die. The wire-drawing die comprises an outer die, and an inner core arranged in the center, wherein a wire hole consisting of an entering area and a working area is formed in the inner core; the diameter of the wire hole is gradually reduced from the entering area to the working area; an L-shaped convex edge is arranged on the inner core; a die hole, comprising an entering chamber, a core chamber and a discharging chamber, is formed in the outer die; the diameter of the entering chamber is not less than that of a wide-opening end of the entering area; the diameter of the discharging chamber is more than that of a narrow-opening end of the working area; an L-shaped groove is formed in the inner wall of the die hole; the outer die is divided into a first die and a second die; a conveying hole which communicates with the entering chamber is formed in the first die or the second die; a feeding hole is formed in one side of the conveying hole, and the upper part of the feeding hole communicates with a feeding hopper; a sliding conveying part is arranged in the feeding hole; an elastic component, which can be pressed by the convex edge to enable the sliding conveying part to convey materials (wire drawing powder), is arranged in the L-shaped groove; and a gap is formed in the convex edge. According to the technical scheme, the wire-drawing die is convenient to replace, and moreover, the frictional coefficients between a product and the wall of the wire hole can be effectively decreased.
