The invention relates to a rubber ring mold with an anti-dislocation structure. When designing the existing rubber ring mold, excessive rubber must overflow at the parting plane to generate burr with certain thickness when the rubber ring mold is in use, thereby generating dislocation or ellipse of the product and influencing the quality of the product. The rubber ring mold with an anti-dislocation structure comprises an upper mold and a lower mold, wherein the thickness of a reserved burr (1) of the upper mold is 0.01-0.03mm, and is equal to that of a reserved burr (2) of the lower mold; the upper mold (3) and lower mold (4) are respectively semicircular; and the cross sections of the upper mold and lower mold are respectively provided with a spherical die cavity (5) and a spherical die cavity (6). The rubber ring mold solves the problem of dislocation, and enhances the roundness and quality of the product.
