Description

Technical Field

[0001] The utility model belongs to the technical field of blow molding, and particularly relates to a blow molding device for mineral water bottles. Background Technique

[0002] Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. The blow molding process began to be used for the production of small low-density polyethylene bottles during World War II. In the late 1950s, with the birth of high-density polyethylene and the development of blow molding machines, blow molding technology has been widely used. The volume of hollow containers can reach thousands of liters, and some productions have adopted computer control. Plastics suitable for blow molding include polyethylene, polyvinyl chloride, polypropylene, polyester, etc., and the resulting hollow containers are widely used as industrial packaging containers. According to the method of making the parison, blow molding can be divided into extrusion blow molding and injection blow molding. Newly developed ones include multi-layer blow molding and stretch blow molding.

[0003] Chinese Patent Application No. 2019223126591 discloses a blow molding forming device for chemical plastic bottles.

The output end of the electric push rod is fixed to the moving mold. The two sides of the right end surface of the clamping plate are fixedly connected with a limiting structure, and the output end of the limiting structure is fixed to the moving mold. By designing the traditional mold into a structure of a fixed mold and a moving mold, this design facilitates moving the moving mold to one side by the electric push rod after the plastic bottle is blow molded, thereby facilitating the removal of the plastic bottle. This design can improve the disassembly and assembly speed during the small-scale production of plastic bottles; the convex block on the moving mold is engaged with the groove on the fixed mold, which facilitates the engagement of the moving mold and the fixed mold, and this design greatly improves the accuracy after the fixed mold and the moving mold are fixed, preventing the raw material from overflowing through the gap between the fixed mold and the moving mold during the injection molding process.

[0004] When the above-mentioned disclosed patent water bottle is cooled and formed and the moving mold and the fixed mold are separated, the water bottle is easily adhered to the inner walls of the fixed mold and the moving mold. The formed water bottle has a relatively high temperature, and there is a risk of scalding when personnel directly hold and demold it by hand. At the same time, the original device does not have a cutting function and cannot cut off the useless parison at the upper ends of the moving mold and the fixed mold after blow molding.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1

[0022] Please refer toFigures 1-4 The utility model provides the following technical solutions: a mineral water bottle blow molding device, including a fixed mold 1, the fixed mold 1 is installed on one side of the upper end of a base 7, a card plate 6 is arranged on one side of the upper end of the base 7, an electric push rod 5 is arranged at one end of the card plate 6 at a position corresponding to the fixed mold 1, a movable mold 4 is arranged at the output end of the electric push rod 5, a plurality of protrusions 8 are arranged at one end of the movable mold 4, a groove 9 corresponding to the protrusions 8 is arranged at one end of the fixed mold 1, a cutting component 3 is arranged on one side of the upper end of the fixed mold 1, and a material ejection component 2 is arranged in both the fixed mold 1 and the movable mold 4.

[0023] Specifically, the ejection assembly 2 includes a push plate 21, an arc plate 22, a slide plate 23, a cavity 24, a spring 25, a slide bar 26 and a limit assembly 27, wherein the fixed mold 1 and the movable mold 4 are both provided with an arc plate 22, slide bars 26 are provided on both sides of one end of the arc plate 22, a push plate 21 is provided at the other end of the slide bar 26, a slide bar 23 is welded on the surface of the slide bar 26, a cavity 24 corresponding to the slide bar 23 is provided inside the fixed mold 1 and the movable mold 4, a spring 25 is provided on the outside of the slide bar 26 at one end of the slide bar 23, and a limit assembly 27 is provided at one end of the fixed mold 1 and the movable mold 4 at a position corresponding to the push plate 21.

[0024] By adopting the above technical scheme, after the water bottle is cooled and formed, the movable mold 4 and the fixed mold 1 are separated. When the water bottle sticks to the inner wall of the movable mold 4 and the fixed mold 1, the push plate 21 is pushed to push the slide plate 23 and the slide bar 26 to slide in the fixed mold 1 and the movable mold 4. The spring 25 is compressed, and the slide bar 26 pushes the arc plate 22 to eject the water bottle in the movable mold 4 or the fixed mold 1. When the push plate 21 is released, the spring 25 stretches and pushes the arc plate 22 to reset. By setting the ejecting component 2, when the water bottle sticks to the inner wall of the movable mold 4 or the fixed mold 1, there is no need for personnel to manually demold, thereby avoiding burns to personnel caused by the high temperature of the water bottle.

[0025] Specifically, the limiting assembly 27 includes a rotating shaft 271, a rotating plate 272, a lever 273, a magnetic block 1 274 and a magnetic block 275, wherein a rotating shaft 271 is provided at a position corresponding to one end of the fixed mold 1 and the movable mold 4 and the push plate 21, a rotating plate 272 is provided at one end of the rotating shaft 271, a lever 273 is provided at one end of the rotating plate 272, a magnetic block 1 274 is provided at one end of the rotating shaft 271, and a magnetic block 275 is provided at a position corresponding to one end of the push plate 21 and the magnetic block 1 274.

[0026] By adopting the above technical solution, when there is no need to push the push plate 21, the rotating plate 272 is moved by the lever 273, and the rotating plate 272 rotates on the side of the fixed mold 1 or the movable mold 4 through the rotating shaft 271. After the rotating plate 272 rotates to one end of the push plate 21, the magnetic block 1 274 at one end of the rotating plate 272 is adsorbed with the magnetic block 2 275 at one end of the push plate 21, so as to achieve the effect of adsorbing and fixing the rotating plate 272. The rotating plate 272 can limit the push plate 21 to avoid the push plate 21 from being pushed by mistake.

[0027] Specifically, the rotating shaft 271 is rotatably connected to both the fixed mold 1 and the movable mold 4 through damping. Slide holes corresponding to the slide rods 26 are provided in both the fixed mold 1 and the movable mold 4. The side of the arc-shaped plate 22 is flush with the inner walls of both the fixed mold 1 and the movable mold 4.

[0028] By adopting the above technical solution, the rotating shaft 271 is not prone to self-rotation, and the slide rod 26 can slide in the fixed mold 1 and the movable mold 4.

[0029] When this embodiment is in use, when the mineral water bottle blow molding device is in use, the device is installed in a suitable position. The electric push rod 1 5 is activated to push the movable mold 4 to be joined with the fixed mold 1. The convex block 8 at one end of the movable mold 4 enters the groove 9 at one end of the fixed mold 1. Then, the mineral water bottle blow molding work is carried out in the fixed mold 1 and the movable mold 4 through an injection molding device. After the water bottle is formed, the electric push rod 1 5 contracts to drive the movable mold 4 to separate from the fixed mold 1. By setting the ejecting assembly 2, after the water bottle is cooled and formed, the movable mold 4 and the fixed mold 1 are separated. When the water bottle adheres to the inner walls of the movable mold 4 and the fixed mold 1, the push plate 21 is pushed to drive the slide plate 23 and the slide rod 26 to slide in the fixed mold 1 and the movable mold 4. The spring 25 is compressed, and the slide rod 26 pushes the arc-shaped plate 22 to eject the water bottle in the movable mold 4 or the fixed mold 1. When the push plate 21 is released, the spring 25 rebounds to push the arc-shaped plate 22 to reset. By setting the ejecting assembly 2, when the water bottle adheres to the inner wall of the movable mold 4 or the fixed mold 1, manual demolding by personnel is not required, avoiding scalding of personnel caused by the high temperature of the water bottle. By setting the limiting assembly 27, when the push plate 21 does not need to be pushed, the turning plate 272 is toggled by the lever 273. The turning plate 272 rotates on the side of the fixed mold 1 or the movable mold 4 through the rotating shaft 271. After the turning plate 272 rotates to one end of the push plate 21, the magnetic block 1 274 at one end of the turning plate 272 adsorbs to the magnetic block 2 275 at one end of the push plate 21, achieving the effect of adsorbing and fixing the turning plate 272. The turning plate 272 can limit the push plate 21 to avoid mis-pushing the push plate 21.

Threaded holes corresponding to the mounting bolts 33 are provided at the upper end of the fixed mold 1, and through holes corresponding to the mounting bolts 33 are provided in the mounting plate 34.

[0034] By adopting the above technical solution, the mounting bolts 33 can pass through the mounting plate 34 and be screwed into the threaded holes at the upper end of the fixed mold 1.

[0035] When this embodiment is in use, by setting the cutting assembly 3, the fixed cover 31 is installed and fixed to the upper end of the fixed mold 1 through the mounting plate 34 and the mounting bolts 33. After the blowing of the water bottle is completed, the electric push rod two 32 is activated to push the moving plate 35 to move. The cutting knife 36 at one end of the moving plate 35 can cut off the useless blank at the upper ends of the moving mold 4 and the fixed mold 1 after blowing. By setting the cutting assembly 3, the device can automatically cut off the useless blank at the upper ends of the moving mold 4 and the fixed mold 1 after blowing, improving the practicability of the device.

[0036] The electric push rod two 32 in the present utility model is an existing publicly disclosed technology, and the selected model is FTG50.

[0037] In the present utility model, the structures and working principles of the fixed mold 1, the moving mold 4, the electric push rod one 5, the clamping plate 6, the base 7, the convex block 8 and the groove 9 have been disclosed in a chemical plastic bottle blow molding device with the Chinese patent application number 2019223126591. Its working principle is to activate the electric push rod one 5 to push the moving mold 4 to be joined with the fixed mold 1. The convex block 8 at one end of the moving mold 4 enters the groove 9 at one end of the fixed mold 1. Then, the mineral water bottle is blow molded into the fixed mold 1 and the moving mold 4 through an injection molding device. After the water bottle is formed, the electric push rod one 5 contracts to drive the moving mold 4 to separate from the fixed mold 1.

[0038] Working principle and usage process of the present utility model: When the mineral water bottle blow molding device is in use, the device is installed at a suitable position, and the electric push rod 1 is activated to push the moving mold 4 to be joined with the fixed mold 1. The convex block 8 at one end of the moving mold 4 enters the groove 9 at one end of the fixed mold 1. Then, the mineral water bottle blow molding work is carried out in the fixed mold 1 and the moving mold 4 through an injection molding device. After the water bottle is formed, the electric push rod 1 contracts to drive the separation of the moving mold 4 and the fixed mold 1. By setting the ejection assembly 2, after the water bottle is cooled and formed, the moving mold 4 and the fixed mold 1 are separated. When the water bottle adheres to the inner walls of the moving mold 4 and the fixed mold 1, the push plate 21 is pushed to drive the sliding plate 23 and the sliding rod 26 to slide in the fixed mold 1 and the moving mold 4. The spring 25 is compressed, and the sliding rod 26 pushes the arc-shaped plate 22 to eject the water bottle in the moving mold 4 or the fixed mold 1. When the push plate 21 is released, the spring 25 rebounds to push the arc-shaped plate 22 to reset. By setting the ejection assembly 2, when the water bottle adheres to the inner wall of the moving mold 4 or the fixed mold 1, manual demolding by personnel is not required, avoiding scalding of personnel caused by the relatively high temperature of the water bottle. By setting the limiting assembly 27, when the push plate 21 does not need to be pushed, the turning plate 272 is toggled by the lever 273. The turning plate 272 rotates on the side of the fixed mold 1 or the moving mold 4 through the rotating shaft 271. After the turning plate 272 rotates to one end of the push plate 21, the magnet 1 274 at one end of the turning plate 272 adsorbs to the magnet 2 275 at one end of the push plate 21, achieving the effect of adsorbing and fixing the turning plate 272. The turning plate 272 can limit the push plate 21 to avoid accidental pushing of the push plate 21. By setting the cutting assembly 3, the fixed cover 31 is installed and fixed to the upper end of the fixed mold 1 through the mounting plate 34 and the mounting bolts 33. After the blow molding of the water bottle is completed, the electric push rod 2 32 is activated to push the moving plate 35 to move. The cutter 36 at one end of the moving plate 35 can cut off the useless blank at the upper ends of the moving mold 4 and the fixed mold 1 after blow molding. By setting the cutting assembly 3, the device can automatically cut off the useless blank at the upper ends of the moving mold 4 and the fixed mold 1 after blow molding, improving the practicability of the device.
