Description

Technical Field

[0001] The utility model relates to the field of molds, in particular to a mold for making a sealing ring. Background Art

[0002] Stamping dies are special process equipment used for cold stamping. The die installed on the press applies pressure to the material to separate or plastically deform it, thereby manufacturing the required parts. This processing method is often used for the processing of metal and non-metal materials and is an efficient and economical manufacturing method.

[0003] At present, after the production of the sealing ring of the automobile fuel tank cap, edge material is generated in the middle, which needs to be cut off by a stamping die. The existing die for cutting the sealing ring includes an upper base plate, a lower base plate, a discharge plate, a punching piece, a fixing piece, an elastic piece and a punching groove. The upper base plate pushes the punching piece to push the sealing ring sleeved on the bottom of the punching piece to the punching groove. When the edge material in the middle of the sealing ring enters the punching groove, the punching piece continues to move downward to cut off the edge material. After completion, the discharge plate is pushed by the elastic piece to push the sealing ring down from the punching piece. The bottom of the stamping piece will be worn after long-term punching. After wear, the bottom of the stamping piece is not in sufficient contact with the edge material when pushing the sealing ring into the punching groove for punching, which may easily lead to incomplete punching of part of the edge material and hang on the sealing ring. Therefore, it is necessary to further improve and optimize it. Utility Model Content
