Novel rubber blank molding die

The utility model discloses a novel rubber blank molding die, and relates to the technical field of rubber blank molding. The novel rubber blank molding die comprises a supporting body (1), a star-shaped die (2), a tail part end surface (3) and a flowing surface (4), wherein the tail part end surface (3) is arranged on the lower side of the outer end of the supporting body (1); the star-shaped die (2) is arranged in the center of the supporting body (1); the flowing surface (4) is arranged on the inner side of the supporting body (1). According to the utility model, the novel rubber blank molding die is simple in structure and reasonable in design, through changing the structure of the original die, the flowing distance of rubber in a die cavity is reduced, the area of the die at the tail part of the star-shaped structure is enlarged, the weight of a molded rubber blank is increased, the molding of a product is guaranteed, the rubber utilization ratio of the product is much closer to the rubber utilization ra
