During the production and processing of cemented carbide stamping dies, an isostatic pressing device is required. The isostatic pressing device is a molding device that works under ultra-high pressure and is widely used in industries such as magnetic materials, ceramics, cemented carbide, high-temperature refractory materials, rare earth permanent magnets, carbon materials, and rare metal powders. However, the current isostatic pressing device still has the following shortcomings:

[0003] For example, the patent document with application number 202221292823.2 discloses an isostatic pressing device with an adjustable bottom plate.
