[0002] Currently, in domestic and foreign markets, the sealing rings still mainly adopt the structure directly bonded and vulcanized by rubber and a skeleton, and the structure with a spring is used in some more demanding places. The spring sheet needs to be produced by stamping through a stamping die during processing. A stamping die is a tool that makes a blank into a workpiece with a specific shape and size under the action of external force during cold stamping processing. The die generally includes a moving die and a fixed die, which can be separated and combined, and the workpiece is taken out when separated. There are certain drawbacks in the use of existing die equipment. After the processing is completed, it is relatively troublesome to take out the model, and the demoulding method of the die itself is not convenient enough. In addition, due to long-term processing, the waste chips generated are likely to cause jamming between components. Content of the Utility Model

[0024] When the present utility model is in use: First, place the top push plate 13 on the upper side of the base 1. Then, after passing the bottom section of the limit table 3 through the conduction groove 15, insert the insertion block 19 at the bottom of the limit table 3 into the insertion slot 21. Then, place the second spring 4 between the top push plate 13 and the base 1.
