Forming mold used in high-pressure rubber hose extrusion process

The utility model discloses a forming mold used in a high-pressure rubber hose extrusion process. The forming mold comprises a mold body, wherein the mold body is arranged at a tube core outlet which clads an inner rubber layer or an outer rubber layer on an extruder; a forming mouth (2) which is formed when the inner rubber layer or the outer rubber layer is cladded by the tube core is formed in the center of the mold body; and the diameter of the forming mouth is equal to the outer diameter of the tube core cladding the inner rubber layer or the outer rubber layer. By adoption of the forming mold, requirements for manufacturing high-pressure rubber hoses by using soft core molds can be met, a phenomenon of core shift caused when the tube core clads the inner rubber layer and the outer rubber layer and comes out of the outlet of the extruder can be avoided, and the inner rubber layer and the outer rubber layer can be uniformly cladded on the surface of the tube core; therefore, the performance of the high-pr
