The port of said sealing ring is provided with the floamed ceramics filtrating piece that is used for aluminum filtration liquid.
Between the said person in charge and the neck bush, also be provided with expansion minuteness seal between the said person in charge and the external bushing.
The said person in charge's end face also is welded with wall thickness greater than the installing ring of being responsible for wall thickness, and said sealing ring is screwed onto on the installing ring.
Said ring assembly is made up of basic ring that is spirally connected and pressure ring; Said basic ring is set in to be responsible for and goes up and end face and external bushing end face welding formation sealing; Said basic ring and neck bush are provided with the annular radial groove, said pressure ring place in this annular radial groove and end face be responsible for end face and be close to form and seal.
After adopting above structure; The utility model compared with prior art; Have the following advantages: the person in charge of steel or irony is arranged with by aluminium carbonate or alumina silicate or carborundum or silicon nitride or corundum or quartzy neck bush and the external bushing that is made; And neck bush and external bushing are made by the aluminium carbonate that is difficult for reacting with aluminium liquid or alumina silicate or carborundum or silicon nitride or corundum or quartz; An end that adds the person in charge is provided with to be close to neck bush and external bushing end face and forms sealing and then prevent the sealing ring that aluminium liquid contacts with the person in charge; And the other end of being responsible for is provided with to be close to neck bush and external bushing end face and forms sealing and then prevent aluminium liquid and ring assembly that the person in charge contacts; Be responsible for directly coming in contact like this, effectively prolonged the person in charge's service life with aluminium liquid, and the earthenware of the relative prior art of combination stalk that is used for the aluminium alloy wheel hub low pressure casting die that assembles through the person in charge, neck bush, external bushing, sealing ring and ring assembly; Production cost is much lower relatively, effectively reduces the production cost of aluminium alloy wheel hub.
As improvement, the port of said sealing ring is provided with the floamed ceramics filtrating piece that is used for aluminum filtration liquid, and the setting of floamed ceramics filtrating piece has been avoided at each cast gate place of mould screen pack being set and come aluminum filtration liquid.
As further improvement, between the said person in charge and the neck bush, also be provided with expansion minuteness seal between the said person in charge and the external bushing, prevented that further the person in charge and aluminium liquid from coming in contact.
As further improvement, the said person in charge's end face also is welded with wall thickness greater than the installing ring of being responsible for wall thickness, and said sealing ring is screwed onto on the installing ring, installing ring the installation that has made things convenient for sealing ring is set.
As further improvement; Said ring assembly is made up of basic ring that is spirally connected and pressure ring; Said basic ring is set in be responsible for to be gone up and end face forms sealing with the welding of external bushing end face, and said basic ring and neck bush are provided with the annular radial groove, and said pressure ring places in this annular radial groove and end face is close to formation with person in charge's end face and is sealed; Ring assembly adopts basic ring and pressure ring to constitute, and sealing is reliable.
