[0001] The utility model relates to the technical field of sealing ring processing, in particular to an oil seal ring extrusion die. Background Art

[0002] As we all know, the oil seal ring extrusion die is a special equipment used to produce oil seal rings. Its main function is to form the seal ring material into the required shape and size through the extrusion process. The die is usually composed of an upper die, a lower die and an extrusion mechanism. The upper die and the lower die are the core parts of the die, and the gap between them determines the size and shape of the extruded seal ring.

When the mold needs to be replaced or maintained, the inconvenient upper and lower molds will significantly affect the production efficiency. The long disassembly and installation process will cause the production line to stop, increase production costs, and limit the flexibility of the mold, making it impossible for the mold to quickly adapt to the production needs of oil seals of different sizes and shapes.
