[0002] Forging dies are essential tools in forging production, used to process metal billets into forgings of specific shapes and sizes. Precision plate forging dies are molds used to manufacture precision plate-shaped parts, and are widely used in many fields such as machinery manufacturing, automobiles, and aerospace. The workflow of precision plate forging dies generally includes steps such as material preparation, heating the billet, die closing and forging, demolding, subsequent processing, and inspection.

[0003] In the existing technology, during the use of precision sheet metal forging dies, the forging surface of sheet metal parts is relatively precise and complex, making it difficult to demold after subsequent die-forming. It is necessary to add a demolding structure inside the die to assist in demolding. However, the demolding structure cannot respond quickly when the die is opened to push out the formed sheet metal parts, which will affect the processing efficiency. Furthermore, the temperature drop of the sheet metal parts will increase the demolding difficulty. Summary of the Invention
