The existing sealing plugs of the high-voltage connectors of the charging gun, as Figure 8 shown, include a sealing plug main body 50. Two sealing plug wire-passing holes 51 are arranged in the sealing plug main body 50. Outer compression convex edges 52 are arranged at intervals on the outer wall of the sealing plug main body 50. Inner compression convex edges 53 are arranged at intervals on the inner wall of the sealing plug wire-passing hole 51. A sealing plug mark 54 is arranged protruding on the upper surface of the sealing plug main body 50. The sealing plug of the high-voltage connector of the charging gun is made of silica gel material and is formed by extrusion on a forming die. It is found in actual production that the height and size of the sealing plug mark 54 cannot be stably controlled, and the consistency of the sealing plug mark 54 after the product is formed is poor. The main reason is that the traditional hand-pressing method for mold closing leads to more flash at the sealing plug mark 54 and large dimensional errors, resulting in a low yield of the product; moreover, since the same sealing plug main body 50 of the existing forming die can only make the same sealing plug mark 54 and cannot be flexibly replaced, the adaptability is poor. Therefore, the existing forming die for the sealing plug of the high-voltage connector of the charging gun is improved and optimized. Content of the Utility Model
