Pipe, is provided with return-air gap between airway outer wall and inducing QI through hole hole wall, and core head is provided with at least one even at gas outlet
Logical return-air gap and the return-air hole of gas outlet, be provided with air inlet radially and the axle being connected with air inlet in air valve mold insert
To gas transmission through hole, gas transmission through hole is connected with airway.
As the preferred scheme of one, described mandrel body is provided with spring at stop nut near the side of core head and installs
Chamber, described back-moving spring is arranged in spring installation cavity and one end pushes against on stop nut.
As the preferred scheme of one, described plug push rod is provided with insulating lid away from the end sleeve of core head.
The invention has the beneficial effects as follows: this plug inputs compressed air from mandrel body one end, and portion gas is in mandrel body
Gap of supplying gas between plug push rod, air valve mold insert and core head and installation through hole hole wall enters the air inlet of air valve mold insert, then
It is introduced into core head inner loop through airway, through airway outer wall and inducing QI by the axial gas transmission through hole of air valve mold insert
Return-air gap, then the return-air through the core head connection return-air gap at gas outlet with gas outlet it is provided with between through hole hole wall
Hole, is blow molded pipe finally by the gas outlet between core head and mandrel body, so can be in first cooling core caput
Portion, carries out internal temperature control to note blowpipe embryo, so that the temperature of core head controls a constant scope, pipe embryo temperature obtains
Preferably control so that blow molding's product body uniform wall thickness.

Detailed description of the invention
Below in conjunction with the accompanying drawings, specific embodiments of the present invention are described in detail.
As shown in Figure 1-2, a kind of note blows with plug, and including being provided with the mandrel body 1 of axially mounted through hole, mandrel body 1 is in peace
It is provided with, in dress through hole, plug push rod 2, air valve mold insert 3 and the core head 4 being sequentially connected with.Core head 4 one end be positioned at mandrel body 1 outer and
And it is provided with gas outlet 5 between mandrel body 1.
Plug push rod 2 is arranged with stop nut 6 away from one end of core head 4, is provided with and stop nut 6 phase in mandrel body 1
The limited step coordinated.Mandrel body 1 is provided with use between plug push rod 2, air valve mold insert 3 and core head 4 and installation through hole hole wall
To input compressed-air actuated gap 7 of supplying gas.It is provided with in mandrel body 1 and makes answering of plug push rod 2, air valve mold insert 3 and core head 4 reset
Position spring 8.Being provided with spring installation cavity at stop nut 6 near the side of core head 4 in mandrel body 1, described back-moving spring 8 is arranged
In spring installation cavity and one end push against on stop nut 6.Plug push rod 2 is provided with insulating lid away from the end sleeve of core head 4
9。
Core head 4 is provided with inducing QI through hole 41, inducing QI through hole 41 is equipped with airway 10, airway 10 outer wall and inducing QI
It is provided with return-air gap 11 between through hole 41 hole wall.Be provided with at gas outlet 5 on core head 4 at least one connection return-air gap 11 with
The return-air hole 42 of gas outlet 5.Air valve mold insert 3 is provided with air inlet 31 radially and the most defeated with what air inlet 31 was connected
Vent hole 32, gas transmission through hole 32 is connected with airway 10.
During work, the liftout attachment in injection blow molding machine withstands insulating lid 9 so that gas outlet 5 between mandrel body 1 and core head 4
Opening, high pressure gas has two trends altogether, A: input compressed air from mandrel body 1 one end, at plug push rod 2, gas in mandrel body 1
Valve mold insert 3 and core head 4 and the gap 7 of supplying gas installed between through hole hole wall, directly pass through the gas between core head 4 and mandrel body 1
Pipe is blow molded by body outlet 5；B: input compressed air from mandrel body 1 one end, at plug push rod 2, air valve in mandrel body 1
Mold insert 3 and core head 4 and the gap 7 of supplying gas installed between through hole hole wall enter the air inlet 31 of air valve mold insert 3, then by air valve mold insert
The axial gas transmission through hole 32 of 3 is introduced into core head 4 inner loop through airway 10, leads to inducing QI through airway 10 outer wall
Return-air gap 11 it is provided with between the hole wall of hole 41, then through the core head 4 connection return-air gap 11 at gas outlet 5 and gas outlet 5
Return-air hole 42, finally by the gas outlet 5 between core head 4 and mandrel body 1, pipe is blow molded, so can be the coldest
But core head 4 is internal, note blowpipe embryo is carried out internal temperature control, to improve product quality.
