Abstract
Description
Technical Field
[0001] This application relates to the field of plastic bottle production technology, and in particular to a molding apparatus for plastic bottle production. Background Technology
[0002] Plastic bottles are essential containers for pharmaceutical packaging and daily life. In the past, plastic bottles were generally produced using blow molding, which uses gas pressure to inflate a hot-melt preform closed in a mold to form a hollow product. Plastic bottles are mainly made of materials such as polyethylene or polypropylene with the addition of various organic solvents. Plastic bottles widely use polyester (PET), polyethylene (PE), and polypropylene (PP) as raw materials. After adding the corresponding organic solvents, they are heated at high temperatures and then formed into plastic containers through blow molding, extrusion blow molding, or injection molding using plastic molds. Plastic bottles have the advantages of being not easily broken, low in cost, and highly transparent.
[0003] Existing plastic bottle production molding equipment generally uses molds and blow molding mechanisms to produce plastic bottles. However, after the plastic bottles are formed, users need to manually collect the finished plastic bottles, which is time-consuming and labor-intensive, reduces production efficiency, and is inconvenient for users. Utility Model Content
[0004] This application provides a molding apparatus for plastic bottle production to solve the problem that existing plastic bottle production molding apparatuses generally use molds and blow molding mechanisms to produce plastic bottles, but after the plastic bottles are molded, users need to manually collect the molded plastic bottles, which is time-consuming and labor-intensive, resulting in reduced production efficiency.
[0005] This application provides a molding apparatus for producing plastic bottles, including a mounting frame body. A first mold is provided at one end of the mounting frame body, and a second mold is slidably connected to one side of the first mold. The first mold and the second mold are slidably connected by a limiting rod. A driving hydraulic cylinder is installed on one side of the first mold, and a hydraulic cylinder drive shaft is installed at one end of the driving hydraulic cylinder. An injection groove is formed at one end of the first mold and the second mold, and a clamping groove is formed at the end of the first mold and the second mold away from the injection groove. A pushing hydraulic cylinder is installed at one end of the first mold, and a hydraulic push rod is installed at one end of the pushing hydraulic cylinder. A molded plastic bottle is clamped inside the clamping groove. A conveyor belt is provided at the right end of the first mold and the second mold, and a conveyor motor is installed at one end of the conveyor belt.
[0006] Preferably, a mounting plate is fixed to the top of the mounting frame body, a drive motor is provided on one side of the mounting plate, a motor drive shaft is installed at one end of the drive motor, and a conveying screw is installed on the outer wall of the motor drive shaft.
[0007] Preferably, a conveying pipe is installed at one end of the mounting plate, and a feed hopper is installed at the top end of the conveying pipe.
[0008] Preferably, a heating sleeve is fitted onto the outer wall of the conveying pipe.
[0009] Preferably, a nozzle is installed at the end of the delivery pipe away from the mounting plate.

[0012] Beneficial effects:
[0013] Considering the existing plastic bottle production molding equipment, plastic bottles are generally produced by molding and blow molding mechanisms. However, after the plastic bottles are formed, users need to manually collect the molded plastic bottles, which is time-consuming and labor-intensive, resulting in reduced production efficiency.
[0014] A preform is injected into the injection tank through a nozzle. Then, by opening the hydraulic cylinder, the hydraulic push rod moves the first and second molds to the right until the injection tank reaches the bottom of the air nozzle. Compressed air is injected into the injection tank through the air nozzle, causing the mold to fully expand, thus completing the molding of the plastic bottle. After the plastic bottle is molded inside the injection tank, opening the drive hydraulic cylinder causes the hydraulic cylinder drive shaft to move the second mold backward. At this point, the molded plastic bottle will be stationary at the top of the limiting base plate. Then, opening the drive hydraulic cylinder again causes the hydraulic push rod to move the first and second molds simultaneously to the left. When the injection tank at the top of the first and second molds moves back to the bottom of the nozzle, opening the drive hydraulic cylinder again causes the hydraulic cylinder drive shaft to move the second mold towards the first mold, thus clamping and fixing the molded plastic bottle through the clamping slot. When the plastic bottle molding operation is repeated, the clamping slot will move the molded plastic bottle to the top of the conveyor belt. By opening the conveyor motor, the molded plastic bottle can be automatically unloaded and collected.

[0032] This utility model provides, for example Figure 1-7 The molding apparatus for producing plastic bottles shown includes a mounting frame body 1. A first mold 10 is provided at one end of the mounting frame body 1. A second mold 11 is slidably connected to one side of the first mold 10. The first mold 10 and the second mold 11 are slidably connected by a limiting rod 12. A driving hydraulic cylinder 13 is installed on one side of the first mold 10. A hydraulic cylinder drive shaft 14 is installed at one end of the driving hydraulic cylinder 13. An injection groove 15 is opened at one end of the first mold 10 and the second mold 11. A clamping groove 16 is opened at the end of the first mold 10 and the second mold 11 away from the injection groove 15. A pushing hydraulic cylinder 17 is installed at one end of the first mold 10. A hydraulic push rod 18 is installed at one end of the pushing hydraulic cylinder 17. A molded plastic bottle 29 is clamped inside the clamping groove 16. A conveyor belt 30 is provided at the right end of the first mold 10 and the second mold 11. A conveyor motor 31 is installed at one end of the conveyor belt 30.
[0033] In this process, a preform is injected into the injection tank 15 through the nozzle 9. Then, by opening the push hydraulic cylinder 17, the hydraulic push rod 18 moves the first mold 10 and the second mold 11 to the right until the injection tank 15 reaches the bottom of the air nozzle 24. Compressed air is injected into the injection tank 15 through the air nozzle 24, causing the mold to fully expand and thus completing the molding of the plastic bottle. After the plastic bottle inside the injection tank 15 is molded, the drive hydraulic cylinder 13 is opened, causing the hydraulic cylinder drive shaft 14 to move the second mold 11 backward. At this point, the molded plastic bottle 29 will be stationary at the top of the limiting base plate 19. Then, the push hydraulic cylinder 17 is opened again... 7. The hydraulic push rod 18 drives the first mold 10 and the second mold 11 to move to the left simultaneously. When the injection groove 15 at the top of the first mold 10 and the second mold 11 moves to the bottom of the nozzle 9 again, the hydraulic cylinder 13 is opened again, causing the hydraulic cylinder drive shaft 14 to drive the second mold 11 to close towards the first mold 10. The molded plastic bottle 29 is then clamped and fixed by the clamping groove 16. When the plastic bottle molding operation is repeated, the clamping groove 16 will drive the molded plastic bottle 29 to the top of the conveyor belt 30. By turning on the conveyor motor 31, the automatic unloading and collection of the molded plastic bottle 29 can be completed.
[0034] The top of the mounting frame body 1 is fixed with a mounting plate 2. A drive motor 3 is provided on one side of the mounting plate 2. A motor drive shaft 4 is installed at one end of the drive motor 3. A conveying screw 7 is installed on the outer wall of the motor drive shaft 4.
[0035] Specifically, by turning on the drive motor 3, the motor drive shaft 4 drives the conveying screw 7 to rotate inside the conveying pipe 5, and the material is conveyed to the nozzle 9 for spraying through the conveying screw 7.
[0036] A conveying pipe 5 is installed at one end of the mounting plate 2, and a feed hopper 6 is installed at the top of the conveying pipe 5.
[0037] Specifically, plastic granules produced from plastic bottles are introduced into the feed hopper 6, and then the plastic granules are introduced into the inside of the conveying pipe 5 through the feed hopper 6.
[0038] A heating jacket 8 is fitted onto the outer wall of the delivery pipe 5.
[0039] During the material conveying process in the conveying pipe 5, the material inside the conveying pipe 5 is heated and melted by the heating sleeve 8 on the outer wall of the conveying pipe 5.
[0040] A nozzle 9 is installed at the end of the delivery pipe 5 away from the mounting plate 2.
[0041] In this process, the preform is injected into the injection tank 15 through the nozzle 9 for molding.
[0042] The bottom ends of the first mold 10 and the second mold 11 are connected to a limiting base plate 19, and the bottom ends of the first mold 10 and the second mold 11 are provided with limiting grooves 28.
[0043] The limiting base plate 19 and the limiting slide 28 can limit the movement of the first mold 10 and the second mold 11, thereby increasing the stability of their movement.
[0044] A fixed frame 20 is installed at the top of the mounting frame body 1. A lifting hydraulic cylinder 21 is installed at the top of the fixed frame 20. A lifting rod 22 is installed at the bottom of the lifting hydraulic cylinder 21. A mounting block 23 is connected to the bottom of the lifting rod 22. An air nozzle 24 is installed at the bottom of the mounting block 23. An air pump 25 is installed at one end of the fixed frame 20. An air extraction pipe 26 is installed on one side of the air pump 25. An exhaust pipe 27 is installed at the end of the air pump 25 away from the air extraction pipe 26.
[0045] When the injection tank 15 moves the preform to the bottom of the air nozzle 24, the lifting hydraulic cylinder 21 is opened, causing the lifting rod 22 to move the mounting block 23 and the air nozzle 24 downward to the appropriate air blowing location. Then, the air pump 25 is turned on, and the gas is drawn out to the exhaust pipe 27 through the air extraction pipe 26. Finally, the gas is discharged by the air nozzle 24, so that the mold fully expands, thereby completing the molding of the plastic bottle.
[0046] Working principle: When using this molding device for producing plastic bottles, the plastic granules produced for the plastic bottles are introduced into the feed hopper 6, and then the plastic granules are introduced into the inside of the conveying pipe 5 through the feed hopper 6. By turning on the drive motor 3, the motor drive shaft 4 drives the conveying screw 7 to rotate inside the conveying pipe 5. The conveying screw 7 conveys the material. When conveying the material in the conveying pipe 5, the heating jacket 8 on the outer wall of the conveying pipe 5 heats and melts the material, and then sprays it out through the nozzle 9.
[0047] The preform is injected into the injection tank 15 through the nozzle 9. Then, by opening the hydraulic cylinder 17, the hydraulic push rod 18 drives the first mold 10 and the second mold 11 to move to the right until the injection tank 15 moves to the bottom of the air nozzle 24. Compressed air is injected into the injection tank 15 through the air nozzle 24, so that the mold fully expands, thereby completing the molding of the plastic bottle.
[0048] After the plastic bottle inside the injection tank 15 is formed, the hydraulic cylinder 13 is opened, causing the hydraulic cylinder drive shaft 14 to move the second mold 11 backward. At this time, the formed plastic bottle 29 will be stationary at the top of the limiting base plate 19. Then, the hydraulic cylinder 17 is opened again, causing the hydraulic push rod 18 to move the first mold 10 and the second mold 11 to the left at the same time. When the injection tank 15 at the top of the first mold 10 and the second mold 11 moves to the bottom of the nozzle 9 again, the hydraulic cylinder 13 is opened again, causing the hydraulic cylinder drive shaft 14 to move the second mold 11 toward the first mold 10 to close, thereby clamping and fixing the formed plastic bottle 29 through the clamping groove 16.
[0049] When the plastic bottle molding operation is repeated, the clamping groove 16 will move the molded plastic bottle 29 to the top of the conveyor belt 30. By turning on the conveyor motor 31, the automatic unloading and collection of the molded plastic bottle 29 can be completed.
[0050] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
