Vertical air flue.
Background technology
The air passage structure of double-wall corrugated pipe extrusion die is used at present：Including being used to form double-wall corrugated inner tube layer
The interior die body of wall and the outer die body to form double-wall corrugated pipe outer wall, the interior die body include intermediate internal layer core model, with
And the internal layer die sleeve outside internal layer core model is coaxially disposed, it is formed between internal layer die sleeve and internal layer core model for the interior of inner wall material flowing
Wall stream road, the outer die body include outer layer core model and coaxial arrangement of the coaxial arrangement outside internal layer die sleeve in outer layer
Outer layer die sleeve outside core model forms the external wall material runner for external wall material flowing between outer layer die sleeve and internal layer die sleeve, described
Air flue is formed between internal layer die sleeve and outer layer core model, if the side shaft end of the internal layer die sleeve passes through the outer of bolt stem and conveyor screw
Conveyor screw is connected to a fixed, and the opposite side shaft end screw thread of internal layer die sleeve has screwed outer wall expansion and put cone, and outer wall expansion puts cone by outer layer core
Mold shaft is provided in outer conveyor screw axially through external spiral body and connects the air admission hole of air flue to holding out against on outer conveyor screw,
The venthole that cone and connection air flue are put axially through outer wall expansion is provided in cone is put in outer wall expansion.The shortcomings that above-mentioned air passage structure
It is：Internal layer die sleeve easily shakes due to bolt looseness in use, and outer wall expansion is made to put cone can not be by outer layer core model axis
To holding out against on outer conveyor screw, and then cause between external spiral body and outer layer core model and outer layer core model puts cone with outer wall expansion
Between can generate gap, so as to cause the external wall material flowed through in external wall material runner easily between external spiral body and outer layer core model gap,
And outer layer core model and outer wall expansion put gap between boring and block air flue into air entering flue, fail so as to cause tubulation, not only seriously
Working efficiency is influenced, and installation and maintenance are cumbersome.

External spiral body phase screwing hermetic and axial when pushing against together, just forms closed and connects simultaneously between middle die sleeve and external spiral body
The first annular inlet plenum of logical air admission hole and separated air flue.
Further, the aforementioned closed separated air flue of double-wall corrugated pipe extrusion die interbedded gas, wherein：In the middle die sleeve with
Together, the shaft end axially pushed against with middle die sleeve phase on air flue seal is in for air flue seal phase screwing hermetic and axially abutting
The second annular inlet chamber room that is closed and connecting separated air flue and venthole simultaneously is just formed between die sleeve, on air flue seal
The annular outlet passageway being connected with venthole is formed between the opposite side shaft end not pushed against axially mutually with middle die sleeve and middle die sleeve.
Through the implementation of the above technical solution, the beneficial effects of the invention are as follows：Air flue good airproof performance effectively prevent flowing through outer
External wall material in wall stream road is into air entering flue and the occurrence of block air flue, and service life is long, and structure is simpler, dismounting repair
It is more convenient, effectively increase working efficiency.
Description of the drawings
Fig. 1 is the structure diagram of the closed separated air flue of double-wall corrugated pipe extrusion die interbedded gas of the present invention.
Fig. 2 is the enlarged diagram of the H parts shown in Fig. 1.
Fig. 3 is the enlarged diagram of the F parts shown in Fig. 1.
Specific embodiment
The invention will be further described in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, Figure 2, Figure 3 shows, the closed separated air flue of double-wall corrugated pipe extrusion die interbedded gas, including by
It is interior to the interior die sleeve 1 being arranged, middle die sleeve 2 and outer die casing 3 is spaced successively outside, formed between interior die sleeve 1 and middle die sleeve 2 for inner wall material
The inner wall material runner 4 of flowing forms the external wall material runner 5 for external wall material flowing between middle die sleeve 2 and outer die casing 3, middle die sleeve 2
Side shaft end is with 6 phase screwing hermetic of external spiral body and axially pushes against together, opposite side shaft end and the air flue seal of middle die sleeve 2
7 phase screwing hermetics and axially abutting together, are provided with the separated air flue 8 axially through middle die sleeve 2, outside in middle die sleeve 2
The air admission hole 9 of separated air flue 8 is provided with axially through external spiral body 6 and connected in conveyor screw 6, is set in air flue seal 7
There is axially through air flue seal 7 and connects the venthole 10 of separated air flue 8；In the present embodiment, middle die sleeve 2 and external spiral body
The circumferential weld that 6 connections are formed can be further improved the leakproofness of separated air flue 8, be effectively prevent in this way by welded seal
Flowing through the external wall material of external wall material runner 5, therefrom the junction of die sleeve 2 and external spiral body 6 penetrates into separated air flue 8 and blocks air flue and show
The generation of elephant；In the present embodiment, the circumferential weld that middle die sleeve 2 and 7 connection of air flue seal are formed is by welded seal, in this way
The leakproofness of separated air flue 8 can be further improved, further effectively prevent flowing through the external wall material of external wall material runner 5 therefrom die sleeve
2 generation with blocking air flue phenomenon in the junction infiltration separated air flue 8 of air flue seal 7；In the present embodiment, mould in the middle
Set 2 and 6 phase screwing hermetic of external spiral body and when axial abutting is together, just form closed between middle die sleeve 2 and external spiral body 6
And the first annular inlet plenum 11 of air admission hole 9 and separated air flue 8 is connected simultaneously, middle die sleeve and external spiral are greatly reduced in this way
Installation accuracy between body, improves efficiency of assembling；In this example, in the middle die sleeve 2 and 7 phase screwing hermetic of air flue seal and
It is axial to push against together, it is just formed between the shaft end axially pushed against with middle 2 phase of die sleeve on air flue seal 7 and middle die sleeve 2 close
Close and connect simultaneously the second annular inlet chamber room 12 of separated air flue 8 and venthole 10, on air flue seal 7 not with middle die sleeve 2
The annular outlet passageway 13 being connected with venthole 10 is formed between the opposite side shaft end mutually axially pushed against and middle die sleeve 2, in this way
The installation accuracy between middle die sleeve and air flue seal is not only greatly reduced, improves efficiency of assembling, and ensure that uniformly
Outlet；
In use, for can be successively through air admission hole 9, first annular inlet plenum by the compressed gas of external wall material blow molding
11st, it is exported after separated air flue 8, the second annular inlet chamber room 12, venthole 10 and annular outlet passageway 13；On the one hand, pass through by
The both sides shaft end of external spiral body 6 screws respectively with middle die sleeve 2 and 7 phase thread seal of air flue seal, then by middle die sleeve 2 and outer spiral shell
Revolve the circumferential weld of circumferential weld that body 6 junction formed and the formation of the shaft end corresponding with air flue seal 7 of middle die sleeve 2 connection into
The connection fixed form of row welded seal not only substantially increases the leakproofness of air flue, effectively prevent flowing through in external wall material runner
External wall material the generation of air flue phenomenon is blocked into air entering flue, and also avoid middle die sleeve and shake in use,
Substantially increase the operation stability of equipment；On the other hand, separated air flue 8 is opened in middle die sleeve, enormously simplifies structure,
Service life is long, and installation and maintenance are more convenient.
