The core joint 29 pushes the inner core 36 upwards through the clamping ring 28, the inner core 36 further drives the outer core 37 to synchronously upwards until the upper surface of the outer core 37 contacts the bottom surface of the inner guide ring 38 of the neck ring die 17, at the moment, the top surface of the inner core guide rod at the upper end of the inner core 36 is aligned with the top surface of the outer core sleeve at the top surface of the outer core 37, and the inner core guide rod and the core sleeve simultaneously penetrate through the guide ring 38 and enter the neck ring die 17. The gob 26 delivered from the gob delivery mechanism is directed by the funnel 59 in the upper end of the blank mold 5 and drops into the blank mold 5 as shown in fig. 10.

And 2, performing gas blowing.

The top of the primary mould 5 is provided with a funnel structure, so that the air-entrapping process is directly carried out after the material dripping is finished, the reciprocating process of the funnel in the prior art is omitted, and the process flow is reduced. The gas-extinguishing head 15 moves to the top of the blank mould 5 under the drive of the gas-extinguishing arm 3, the gas-extinguishing head 15 descends under the drive of the gas-extinguishing arm 3, after the gas-extinguishing head 15 is in butt joint with the blank mould 5, a conical surface which is thick at the upper part and thin at the lower part of the gas-extinguishing head 15 is attached to a funnel opening 59 at the top of the blank mould 5, and meanwhile, a groove on the lower surface of a boss at the middle part of the blank mould 5 is clamped on the outer ring of the boss at the top of the blank mould 5, so that the split blank mould 5 is locked.

The gas enters the air-puffing air cylinder 24 through the air-puffing arm pipeline 23 to push the air-puffing piston 21, the air-puffing piston 21 overcomes the elastic force action of the air-puffing spring 22 to descend, and simultaneously drives the air-puffing rod 25 to descend. After descending, the air-entrapping rod 25 forms a gap with the bottom of the air-entrapping head 15, and air flow enters the blank mold 5 through the air-entrapping head to entrap the gob 26 in the blank mold 5. The gob 26 is forced into the die 17 to form the finish structure. As shown in fig. 11.

And step 3, reversely blowing.

After the air-puffing process is completed, the air-puffing rod 25 is reset under the action of the elastic force of the air-puffing spring 22, and at the same time, the opening at the bottom of the air-puffing head 15 is blocked. At this time, the piston rod of the pressure-blowing cylinder 35 is in a free state, the core spring 31 is reset, the piston rod of the pressure-blowing cylinder 35 is pushed to move downwards through the lower retainer ring 48, the core joint 29 is driven to move downwards when the piston rod of the pressure-blowing cylinder 35 moves downwards, the core joint 29 drives the inner core 36 to move downwards through the clamp ring 28, the inner core guide rod at the upper end of the inner core 36 is separated from the outer core sleeve at the top surface of the outer core 37 at this time, meanwhile, the top surface of the inner core 36 is separated from the outer core 37 to form a gap, and the upper port of the inner core channel 27 is opened. The air blown from the blowback pipe passes upward through the hollow screw 67 into the core sub-passage 27 and is blown out from the upper port of the core sub-passage 27. The air blown out from the inner core sub-channel 27 is further blown out from the opening at the top of the outer core sleeve into the mouth mold 17 through the gap between the inner core guide rod and the outer core sleeve to blow back the gob 26. After the completion of the back-blowing process, the gob 26 forms a parison body inside the parison mold 5. As shown in fig. 12.

Due to the structure that the inner core guide rod at the top of the inner core 36 and the outer core sleeve at the top of the outer core 37 are sleeved inside and outside, when the gob 26 in the blank mold 5 is not solidified, the outer core sleeve continues to cool the gob 26 at the neck mold 17 through heat conduction, and simultaneously blocks the neck opening which is not completely solidified, so that the gob 26 is prevented from being removed from the neck mold 17 integrally during reverse blowing.

And 4, turning over.

The piston rod of the pressure air blowing cylinder 35 descends to drive the base 33 to descend, the outer sleeve 32 is driven to descend through the base 33, and the outer core 37 is driven to descend through the outer sleeve 32; the piston rod of the pressure-blowing cylinder 35 simultaneously drives the core joint 29 downward, and the core joint drives the inner core 36 downward through the clamping ring 28. Eventually causing the outer core sleeve to be ejected from the die 17.

The blank mold clamping mechanism 2 drives the blank mold 5 to separate, and the forming mold clamping mechanism 7 drives the forming mold 10 to separate. The turnover mechanism 8 works to drive the mouth clamp fixture 6 to turn over, the mouth mold 17 synchronously turns over under the clamping action of the mouth clamp 16 in the mouth clamp fixture 6, the parison blank formed by the inverted blowing of the gob 26 turns over to the molding side along with the mouth mold 17 and enters the molding die 10, and the molding die fixture mechanism 7 controls the molding die 10 to fold.

And 5, blowing.

An air blowing piston rod 39 in the positive air blowing mechanism 12 drives the air blowing arm 13 to move to the upper port of the forming die 10, the air blowing arm 13 descends, so that an air blowing head 47 at the lower end of the air blowing arm 13 is in butt joint with the mouth die 17, and after the air blowing arm 13 is in butt joint with the forming die 10, the air blowing head 47 enters the mouth die 17 and is in contact with the upper surface of the guide ring 38.

An external air source positively blows air into the forming die 10 through an air blowing channel formed by the air blowing gland 43, the air blowing spring 44, the air blowing pressure ring 45, the air blowing lock ring 41 and the central hole of the air blowing head 47, so that the blank body is formed in the forming die 10. As shown in fig. 13. After the positive blowing is completed, the reversing mechanism 8 drives the mouth clamp 6 to rotate reversely, and the mouth clamp 6 and the mouth die 17 held by the mouth clamp 16 are simultaneously returned to the prototype side.

The turnover mechanism 8 can also drive the mouth-piece clamp 6 to rotate reversely before forward blowing, so as to bring the mouth-piece clamp 6 and the mouth-piece 17 clamped by the mouth-piece 16 back to the prototype side, at this time, a blowing piston rod 39 in the forward blowing mechanism 12 drives the blowing arm 13 to move to the upper port of the forming die 10, the blowing arm 13 descends to be directly butted with the upper port of the forming die 10, the blowing head 47 enters the forming die 10, an external air source blows air into the forming die 10 forward through a blowing channel formed by a blowing gland 43, a blowing spring 44, a blowing clamping ring 45, a blowing locking ring 41 and a central hole of the blowing head 47, so that the prototype blank is formed in the forming die 10.

And 6, transferring.

On the forming side, after the glass bottle is formed in the forming mold, the forming mold clamping mechanism 7 drives the forming mold 10 to separate, the bottle clamping mechanism 11 acts to transfer the formed bottle out of the forming mold 10, and the formed bottle is transferred to a stop plate (not shown in the figure), and then the formed bottle is conveyed to a net belt (not shown in the figure) of a bottle conveying machine through a subsequent bottle pulling mechanism (not shown in the figure) in a centralized way.
