Description
Technical field
It the utility model is related to a kind of die feeding mouth sealing device, and in particular to it is soft that one kind is used for isostatic pressing process
Property die feeding mouth instant sealing device.
Background technology
Isostatic pressing process is a kind of manufacturing process of near-net-shape, and its process is the flexibility using quality of rubber materials
Mould, load powdered or granular material to be formed, be put into isostatic pressing machine working cylinder internal liquid medium, adopt after sealing
With the mode for carrying liqs medium be pressurized to more than 100MPa, realize and the surface of flexible die is uniformly pressed, so as to reach
To the purpose of shaping.
After conventional flex mold charge, using manually oral area install rubbery stopper, then on the outside of charging aperture cylindrical section
Manually fastened using clip, so as to realize the sealing of flexible die, prevent thering is liquid to enter mould inside in pressurization.Should
Although mode can realize the sealing of flexible die charging aperture, due to being manual operation, it is unfavorable for automated production, production effect
Rate hardly results in raising.Meanwhile the material of general isostatic pressing process is powdered, a small amount of fly is had during sealing
The fine particles raised enter human body, and certain influence is produced to operator's health.Therefore, it is necessary to invent a kind of encapsulating method and
Device, realizes the fast sealing after flexible die charging, i.e., to ensure sealed reliable, is beneficial to realize automated production again.
Utility model content
One of the purpose of this utility model be to provide it is a kind of seal it is fast and reliable, be easy to automated production be used for etc. it is quiet
Molded craft flexibility die feeding mouth instant sealing device.
What the utility model was realized in：
One kind is used for isostatic pressing process flexible die charging aperture instant sealing device, including flexible die charging aperture circle
The round platform to stretch out arranged at the steel bushing outside shell of column, steel bushing top, at the top of steel bushing with the top of flexible die charging aperture cylindrical section
Highly maintain an equal level, inside flexible die charging aperture cylindrical section, be provided with sealing-plug and supporting expansible stopper, sealing-plug is outside cylinder
Inner circle wimble structure, expansible stopper generally circular cone structure, the cylindrical shell of column of sealing-plug and flexible die charging aperture cylindrical section inwall are small
Gap coordinates, and sealing-plug female cone is identical with the outer cone taper of expansible stopper.Sealing-plug sealed bottom, sealing-plug top have outwards
The round platform of extension.There is a centre bore run through among expansible stopper, the end face at the top of expansible stopper, be provided with centered on centre bore
One cross recess.
The instant sealing device also includes a support frame, is provided with U-type groove on support frame, U-type groove both sides away from
From the external diameter more than steel bushing, the diameter of the round platform to stretch out less than steel bushing top.
The instant sealing device also includes a pressure head, for by expansion sleeve indentation sealing plug.
Further scheme is：The sealing-plug is elastomeric material, and the expansible stopper is metal material, sealing-plug with it is swollen
Swollen plug is the assembled state with pretightning force.
Further scheme is：The round platform that sealing-plug top stretches out and flexible die charging aperture cylindrical section upper surface
And steel bushing upper surface.
In the utility model, steel bushing bottom roundlet shell of column is used to limit sealing-plug range of expansion, plays and bears expansible stopper and squeeze
Densification front cover produces the effect of radial load.Steel bushing top round platform, when contacting with support frame, it can bear to push to pressure head
Power, avoid because lower pressure causes flexible die to collapse.Sealing-plug top round platform and flexible die charging aperture upper surface and steel bushing
Upper surface, for preventing sealing-plug from moving down.Centre bore be used in expansible stopper folding process discharge expansible stopper with it is close
Blocking pre-assembled produces the air in space, prevents from producing gases at high pressure；Expansible stopper upper surface cross recess is exhaust passage, is prevented
Central exhaust port is blocked when only pressure head contacts with expansible stopper.
It is of the present utility model to be used for isostatic pressing process flexible die charging aperture instant sealing device, it is being embodied
When, step is as follows：
The flexible die oral area cylindrical section that steel bushing assembling is finished in charging, the U of support frame is integrally put into after assembling
In type groove, make steel bushing top round platform bottom surface and support frame upper surface.Control pressure head pushes, and expansible stopper indentation sealing plug is justified
Bore intracavitary.Expansible stopper, because diameter gradually increases, makes sealing-plug cylindrical section outwards expand in folding process, coordinates flexible die
Have the restriction effect of steel bushing outside charging aperture, the elastomeric material between expansible stopper and steel bushing is extruded, so as to reach sealing
Effect.
Flexible die after sealing is put into isostatic pressing machine working cylinder internal liquid medium and is pressurized, superhigh pressure liquid
The outside of whole flexible die is acted on, when superhigh pressure liquid acts on expansible stopper large end face, sealing structure is played and more pressed
Tighter effect, it can preferably play sealing function.
During the utility model utilizes the expansible stopper pressure such as sealing-plug with taper surface, expanding radial force is produced, is matched somebody with somebody
Close the restriction effect of outside steel bushing so that the elastomeric material between two metalworks produces extruding, reaches sealing effectiveness.Meanwhile
Under superhigh pressure liquid environment, superhigh pressure liquid forms external pressure to mould and seal assembly, due to expansible stopper large end face outside
It portion, the more can press the more tight under liquid pressure effect, advantageously in sealing.
During use, it is only necessary to by steel bushing, combination sealing plug and mould simply assemble, compress expansible stopper and move
Make mechanism or pneumatic power etc. can be used to complete, it is simple, convenient.If using automation equipment or mechanism, steel bushing is realized
With the assembling of combination sealing plug, then whole seal process can realize full-automation it is unattended, production efficiency is greatly improved.
