Description

Technical Field

[0001] The utility model belongs to the technical field of sealing ring processing devices, in particular to a double-acting lip sealing ring processing device. Background Art

[0002] The sealing of the lip seal ring is achieved by deforming its lip under the action of liquid pressure, so that the lip edge is close to the sealing surface, and it has good sealing performance.

[0003] Lip seals are generally processed by injection molding. Commonly used lip seals are divided into two structures: Y-type and V-type. Due to their special shape and structure, during injection molding, the structure of the injection mold also needs to be Y-type or V-type. This special structure of the injection mold is inconvenient when unloading, which will make the molded lip seal fit tightly with the injection mold and difficult to unload. If it is torn off manually, it will not only increase the labor intensity of the staff, but also easily cause damage to the lip seal due to the large force. Utility Model Content

[0022] When in use, first move the molding lower mold 14 to the position directly below the molding upper mold 12. At this time, the hydraulic rod 11 drives the molding upper mold 12 to move downward, so that the molding upper mold 12 fits with the molding lower mold 14. Then start the lifting cylinder 2, and drive the lifting support platform 4 to rise through the lifting cylinder 2.
