[0002] The flexible graphite packing ring, usually simply referred to as a graphite ring or a graphite gasket, is also known as a self-tightening sealing graphite packing ring. It is made of pure flexible graphite paper, which is cut and then spirally wound and pressed in a mold to form a ring-shaped graphite packing with a 45-degree angled opening. This material is particularly suitable for sealing high-temperature and high-pressure parts, such as the 45-degree angled self-tightening potential commonly used in the power system. The flexible graphite packing ring has good compression and resilience characteristics, or can be said to have an expansion feature.

[0003] During the process of personnel using a pressing mechanism to process a flexible graphite packing ring, affected by the different sizes of the flexible graphite packing rings in production requirements, personnel need to replace the adapter mold according to the actual production requirements to match the flexible graphite packing ring. If the operation of installing or disassembling the adapter mold is relatively complex for personnel, it will lead to an increase in the work burden of personnel, thus reducing the convenience provided by the pressing mechanism to personnel. Therefore, a pressing structure for a flexible graphite packing ring is hereby proposed. Content of the Utility Model
