Specific embodiment

The utility model is further elaborated below by way of specific embodiment:

As shown in Figure 1, a kind of equipment for blowing, including the mold for fixing bottle base 300 and can be formed to bottle base 300 400, the mold 400 is cylindrical and is made of the half module that two panels can open and close, and the bottle body of bottle base 300 is placed on mold 400 It is interior, there is the semi-circular hole closure by being set on the half module of both sides to be formed by circular opening 401 at the top of mold 400, bottle base 300 Bottleneck is stretched out from aperture 401, and the surface of the aperture 401, which is equipped with, blows a bottle nozzle, and blowing a bottle nozzle and being mounted on can drive thereon On first cylinder of lower movement, blows bottle nozzle and can extend into the bottleneck of bottle base 300 and blow to it, so that after heating and softening The inner wall that can expand in the case where being blown into gas effect close to mold 400 of bottle base 300 formed.

The bottleneck structure of the bottle base 300 is as follows: it is from top to bottom successively arranged threaded portion and protrudes from threaded portion and is used for To the support ring 301 that bottle cap is limited, when bottle base 300 is in mold 400,400 aperture 401 of mold is stretched out in threaded portion Outside, support ring 301 is against on mold.

The structure for blowing bottle nozzle is as follows comprising inner nozzle 100 and outer nozzle 200,100 arranged concentric of inner nozzle is in outer In nozzle 200, it is connected with piston rod 102 at the top of inner nozzle 100, is equipped with spring chamber 105, piston rod 102 at the top of piston rod 102 It is moved by the elastic force of own wt and spring, piston rod 102 is equipped with multiple through-holes being connected with outer nozzle 200, air pump (not shown) is connected with the outer wall of spring chamber 105, and air is sent into piston rod 102 from spring chamber 105, is sent into and lives Air in stopper rod 102 can be connected to outer nozzle 200 by the through-hole on piston rod 102, and reaching makes inner nozzle 100 and outer nozzle The effect that 200 pressure are consistent.

100 bottom of inner nozzle is equipped with the sealing shroud 101 of adaptation bottleneck inner wall, on the outer wall of the sealing shroud 101 circumferentially It is disposed with annular flange 103, inner nozzle 100, which protrudes into bottleneck and with the close contact of bottleneck inner wall, when use prevents gas leakage, annular Flange 103, which withstands bottleneck top, prevents gas from flowing out from the gap in sealing shroud 101 and bottleneck inner wall.

The sealing shroud 101 is equipped with multiple through-holes being connected with inner wall at the outer wall being located at below annular flange 103, from And bottleneck external and internal pressure unanimously prevents it deformation occurs when can ensure inflation.

In addition, the sealing shroud 101 be located at annular flange 103 above outer wall at be additionally provided with it is multiple between outer nozzle 200 Connected through-hole, equally playing connection inner nozzle 100 and outer nozzle 200 makes it keep the consistent effect of pressure

200 bottom of outer nozzle is equipped with the sealing ring 201 that can withstand bottleneck support ring 301, gas can be prevented from bottle Mouthful with flowed out in the gap of 200 contact position of outer nozzle, pass through the fixed company of outer nut formula screw between sealing ring 201 and outer nozzle It connects.

Using the design, when in use, the sealing ring 201 of 200 bottom of outer nozzle is transported downwards under the driving of the first cylinder Row resists the support ring 301 of bottleneck, and the sealing shroud 101 of 100 bottom of inner nozzle is run down under the driving of the second cylinder to be resisted Bottleneck inner wall stretches bottle base in the bottle embryo that stretch rod 104 extends downwardly into heating and softening under the driving of the second cylinder, and stretching finishes Post-tensioning boom 104 is withdrawn, and air pump inflates into inner nozzle 100 simultaneously, by using the through-hole for being connected to inner nozzle and outer nozzle, The consistent of pressure between bottleneck inside and outside wall is maintained, prevents bottleneck from generating deformation, closes support ring by using sealing ring 201 301, compressed air is completely blocked will not leak in bottle base 300, and gas can be completely used in bottle base 300 Air blowing will not waste, and lead to bottle base in the gap that will not be penetrated between mold 400 and bottle base 300 because of leaked gas 300 outer surfaces generate bubble, crude and other issues.

But those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate this Utility model, and being not used as the restriction to the utility model, if in the spirit of the utility model, to Variation, the modification of the upper embodiment will all be fallen in the Claims scope of the utility model.
