Ring die with taper hole structure

The utility model relates to the technical field of ring dies, and discloses a ring die with a taper hole structure, which comprises a ring die main body, side flanges are fixedly connected to the upper side and the lower side of the ring die main body, the outer diameter of each side flange is larger than that of the ring die main body, and a die hole is formed in the surface of the ring die main body in a penetrating manner. The center line of the die hole is deviated from the central axis of the circular die main body, the die hole comprises a thin hole and a thick hole, and the diameter of the thin hole is smaller than that of the thick hole. According to the circular mold, the mold hole is obliquely formed, and the inclination direction of the mold hole faces the rotating direction of the pressing roller, when the pressing roller rotates, raw materials can be extruded, the raw materials can be directly extruded into the mold hole, and therefore the raw materials are more smooth when being extruded compar
