With reference to Figure of description 1-4, illustrate the dependency structure of the present invention in block diagram form.In Fig. 1, for cutting somebody's hair 2,
According to conventional understanding, with this of head end and tail end routine reference system, and side where the head end in cephlad-caudal is logical
Frequently referred to front side, and side where tail end is then rear side.
Meanwhile for assembly of cutting somebody's hair, since the pipe 13 of interior high pressure forming device is all pipe fitting, although being not necessarily circle
Pipe, but have nominal axis.
The end face of pipe 13 is pressure-bearing surface, realizes that feed supplement, part to be formed are then based on internal relatively high by 2 propulsions of cutting somebody's hair
Shaping medium be molded by fluid power.
In view of this, a kind of interior high-pressure molding pressing device, refers to the start part at 13 both ends of pipe, that is, passes through interior high pressure
It is molded 13 pipe end of pressing device pushing tow pipe, is used for feed supplement, meanwhile, high-pressure molding pressing device is set in one or both of which
Just like hydraulic tube 8 shown in Fig. 1 and 2（Essence is hydraulic pressure runner, the referred to as hydraulic tube for summary）, imported to the tube chamber of pipe 13
The shaping medium of given pressure.
It is typically simple integral piece that traditional interior high-pressure molding, which pushes away pressing device, and often simple depend on is cut somebody's hair for sealing
With the positive of pipe nozzle, it is easy to cause shaping medium decompression.In the present invention using including cutting somebody's hair assembly and driving pushes away
The driving device that moves along its axis of head assembly, generally speaking, blocking are cut somebody's hair assembly, so as to by adjusting it is therein certain
A little structures promote its performance.
Specifically, about the assembly of cutting somebody's hair, referring to Figure of description 1 and 2, including：
Cut somebody's hair 2, for externally threaded external member, generally speaking, cutting somebody's hair 2 is equivalent to a threaded sleeve structure, therein

As it can be seen that second part is also an assembly structure in Fig. 2, second of the axis body of matrix, that is, multi-diameter shaft above-mentioned
Point, the internal diameter than pipe 13 is small., it should be understood that constrained by mold self structure, the axis of pipe 13 and 2 axis of cutting somebody's hair are bases
This is consistent, therefore, does not consider whether second part contacts with the inner wall of pipe 13 in the present invention, and preferably with not connecing
Tactile structure, is conducive to loading and unloading.
In turn, it is arranged the sealing ring 4 with blister cavities 12 on the second portion；As previously mentioned, under normal condition, sealing ring 4
Be deformed by mechanical presses between sealing surface, to form relatively good sealing, as shown in Fig. 2, blister cavities 12 not
Under inflated condition, the centrifugation side of sealing ring 4 still retains a certain distance with pipe 13, to be conducive to cut somebody's hair 2 work into
It exits, and therefore sealing ring 4 will not generate abrasion.
In turn, sealing ring 4 herein is different under conditions of conventional 4 anatomic structures of sealing ring filling sealing cavity portion still
There is surplus, but need the gas for being filled with given pressure, makes its expansion.
Specifically, it as shown in Fig. 2, in the axial in addition to setting is used as the hydraulic tube 8 in shaping medium channel of plug 5, also sets
It is equipped with for being connected to the blister cavities 12 to provide the tracheae 3 of compressed gas.
Before being filled with shaping medium, tracheae 3 is first opened, blister cavities 12 is made to expand, formation plug 5 is close with 13 nozzle of pipe
Envelope.
In some embodiments, as shown in figure 3, the centripetal side of the blister cavities 12 is open architecture, the tracheae 3 includes position
In the radial component of the axial component and connection blister cavities 12 and axial component of plug axial direction.
About open architecture, be conducive to the assembly of sealing ring 4, i.e., it need not be in the pipe of the circumferential alignment tracheae 3 of plug 5
Mouthful.
About open architecture, sealability is based on crimp, the side of the sealing ring 4 of open architecture there is no declining
Wall can be formed between the interface of sealing and effectively be contacted.
About the positioning of sealing ring 4, the trailing flank of sealing ring 4 is resisted against the leading flank of collar, and the leading flank of sealing ring 4 is
One baffle ring or end cap 6 are constrained.
And in further embodiments, the blister cavities 12 is in the annular using sealing ring axis as axis of sealing ring 4
Chamber, and centripetal side is equipped with the air admission hole 14 for connectivity trachea 3；This kind of structure is in contrast than the structure in a kind of upper embodiment
Sealability it is slightly higher.
The tracheae 3 includes the radial component of the axial component and connection blister cavities 12 and axial component positioned at plug axial direction.
Similarly, the trailing flank of sealing ring 4 is resisted against the leading flank of collar, and the leading flank of sealing ring 4 is a baffle ring or end
Lid 6 is constrained.
In order to obtain better seal and form effective positioning to sealing ring 4, in the second part institute of setting sealing ring 4
The position at place is arranged using the axis of plug 5 as the annular groove of axis, and the diameter of the circle of sealing ring 4 is roughly the same with the internal diameter of annular groove.
About the end cap 6, it is mainly used for the axis location of sealing ring 4, the outer diameter of end cap 6 can refer to existing cut somebody's hair
It is insinuated into the outer diameter of pipe 13, is slightly less than the internal diameter of pipe.In Fig. 2 for clarity represent end cap 6, make the inner wall of pipe 13
Larger gap is kept with end cap, the signal only summarized, the gap can be very small, can reach in some embodiments
The rank of tolerance fit.
In addition, about the sealing ring 4, hermetic seal ability can use following means to improve sealability, specifically join
See Figure of description 3（Partial shows sealing ring 16）, side be equipped with it is multiple using 4 axis of sealing ring as the annular ridge of axis, i.e.,
The height of sealing ring 16 shown in figure, sealing ring can refer to infiltration of the surface tension of shaping medium to 4 material of sealing ring,
Make the shaping medium being permeated, not across adjacent sealing ring 16.
It is found in practical application, and the annular ridge of nonuniform noise can play better seal effect, by reasonable
Layout annular ridge perhaps can play better effect, specifically, can be more using a kind of annular ridge of uneven distribution
It is effective to improve sealing effect.
In addition, the quantity about annular ridge, is advisable with being no less than 3, but it is also unsuitable excessive, no more than 8, preferably
5, optional 4 or 6, when being very few, actual liquid infiltration path is too small, and there is no significantly carry sealing effect
It rises, infiltration span can not at most be avoided by crossing.
About the driving device, traditionally, often use hydraulic cylinder realize the bigger work of power density into, if
It is inaccurate when the axial push-in stroke of offer and axial thrust, it cuts somebody's hair and will appear prodigious collision when contact with pipe fitting
