Description

TECHNICAL FIELD

[0001] The utility model relates to plastic bottle manufacturing equipment technical field, specifically for a bottle body reinforcing press mould of PE bottle manufacturing equipment. BACKGROUND

[0002] Plastic bottles are mainly made of polyethylene or polypropylene and other materials and added with various organic solvents, and the main types of plastic bottles include polyester (PET), polyethylene (PE) and polypropylene (PP), etc. After high-temperature heating, the plastic material is blow molded, extrusion blow molded or injection molded through a plastic mold. In the manufacturing process, the strength and shape of the bottle body need to be stabilized, so a special reinforcing press mold is generally required.

[0003] In the manufacturing of existing PE bottles, especially when the plastic material is brought to the designated position by the blow molding mechanism, the reinforcing press mold needs to be closed to cool and shape the plastic material to be blow molded.

The overall operation is complex and inconvenient, and the operation cost is also high. In addition, the mold is generally cooled by water cooling, but some water vapor may accumulate inside the machine during cooling, which may affect the subsequent cooling process. A special air drying device is needed to circulate the air flow, and the use effect is poor.

It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0031] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0032] The following describes, with reference to the accompanying drawings, some embodiments of a bottle body reinforcing pressing mold provided by this utility model for PE bottle manufacturing equipment.

[0033] Example 1:

[0034] Combination Figures 1-3 As shown, this utility model provides a bottle body reinforcing pressing mold for PE bottle manufacturing equipment.

[0035] Specifically, the assembly includes a chassis 1, a blow molding mechanism 4, and two sets of mold main components 2. Two sets of electric lifting rods 3 are symmetrically installed at the top of the blow molding mechanism 4. A work platform 7 is mounted in the center of the chassis 1. Four sets of extended mounting plates 9 are installed on the upper and lower ends of the work platform 7 on the inner sides of the chassis 1. Two sets of push-pull gear rods 8 are symmetrically installed on the left and right sides of the blow molding mechanism 4. Two sets of first transmission gear columns 14 are symmetrically and rotatably mounted on the inner sides of the chassis 1 on both sides of the work platform 7. One end of each set of first transmission gear columns 14 is connected to a threaded drive near the outer side of the work platform 7. Rod 13, the outer threaded drive sleeve of the threaded rotating rod 13 is connected to a telescopic sleeve 15 that is connected to one end of the two sets of mold main parts 2. The two sets of push-pull toothed rods 8 are respectively slidably locked between the extension mounting plates 9. The inner top of the machine box 1 is slidably locked with a movable hoist 23. The movable hoist 23 is mainly for easy installation. The electric telescopic rod 3 hoists the blow molding mechanism 4 and moves it back and forth laterally through the external transmission mechanism, driving the movement of the blow molding mechanism 4. The top ends of the two sets of electric lifting rods 3 are connected to the bottom ends of the movable hoist 23. The output extension ends of the two sets of electric lifting rods 3 are connected to the blow molding mechanism. The top transmission connection of 4 is such that the rear end faces of the two sets of push-pull gears 8 mesh with the outer surfaces of the two sets of first transmission gears 14. Two sets of first sliding grooves 16 are symmetrically provided on both sides of the top of the housing 1. The first sliding grooves 16 mainly stabilize and limit the movement of the push-pull gears 8, preventing them from shifting position and affecting the meshing transmission of the first transmission gears 14 and the second transmission gears 19. The side extensions of the two sets of push-pull gears 8 are slidably engaged with the inner sides of the two sets of first sliding grooves 16. Second sliding grooves 21 are symmetrically and annularly provided in the middle of the left and right sides of the workbench 7. The second sliding grooves 21 mainly... The movement of the telescopic sleeve 15 is stabilized and limited. The outer extension end of the telescopic sleeve 15 is slidably engaged with the inner side of the second slide groove 21. Water injection pipe 10 and drain pipe 11 are symmetrically installed through the upper and lower outer sides of the two sets of mold main components 2. Cooling cavities 22 are opened inside the two sets of mold main components 2. The cooling cavities 22 are mainly for facilitating the injection of cooling water and cooling the mold main components 2. At the same time, they can also cool the blow-molded material. One end of the water injection pipe 10 and the drain pipe 11 both extend through the side of the machine box 1 to the outside, and the other end is connected to the inside of the cooling cavity 22.

[0036] Example 2:

[0037] Combination Figure 1 As shown, based on Example 1,

[0038] Specifically, two sets of second transmission gears 19 are symmetrically and rotatably mounted on the inner bottom side of the chassis 1. The two sets of second transmission gears 19 are meshed and driven by the up-and-down movement of the push-pull gear 8, which simultaneously causes the exhaust fan 17 and the exhaust fan 18 to rotate and draw in and out, facilitating the flow of gas. One end of the two sets of second transmission gears 19 is connected to the exhaust fan 17 and the exhaust fan 18, respectively. The rear side of the bottom extension end of the two sets of push-pull gears 8 meshes and drives the outer side of the two sets of second transmission gears 19. The other end of the two sets of second transmission gears 19 is provided with a ventilation mesh 20 that is embedded in the chassis 1 in a ring. The ventilation mesh 20 mainly facilitates the intake and exhaust of the exhaust fan 17 and the exhaust fan 18, while filtering dust.

[0039] Combination Figure 1 and Figure 2 As shown, in the above embodiments,

[0040] Specifically, a storage frame 12 is slidably provided at the bottom inner end of the housing 1. The storage frame 12 is mainly used to collect the processed PE bottles, so that they can be pulled out of the outside as a whole through the pull plate 6. The front end of the storage frame 12 is connected to the pull plate 6 on the outside of the housing 1. The front end of the blow molding mechanism 4 is provided with a through hole 5 on the outer side of the housing 1. The through hole 5 is mainly used to facilitate the movable crane 23 to move the material carried by the blow molding mechanism 4 to the top of the two sets of mold bodies 2.

[0041] The working principle and usage process of this utility model are as follows: In use, the external transmission mechanism first moves the movable crane 23 laterally back and forth within the housing 1, and moves the material below the blow molding mechanism 4 at the bottom of the electric lifting rod 3 through the through hole 5 to the top of the two sets of mold main components 2. Simultaneously, the operation of the electric lifting rod 3 causes the blow molding mechanism 4 to move downwards, driving the push-pull gear 8 to move up and down, and engaging the first transmission gear 14, causing the threaded rotating rod 13 to rotate and the threaded transmission telescopic sleeve 15 to move laterally, pushing the two sets of mold main components 2... The main mold components 2 are locked together to seal the material. When the blow molding mechanism 4 blow molds the material, the two sets of main mold components 2 cool and solidify the molded PE bottle. After the reverse operation, the two sets of main mold components 2 are released, allowing the PE bottle to fall into the storage box 12. At the same time, the up and down movement of the push-pull gear 8 also meshes with the two sets of second transmission gears 19, causing the exhaust fan 17 and exhaust fan 18 connected to each other to rotate, playing the role of exhaust and ventilation, making the airflow inside the machine box 1 faster and drying.

[0042] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
