Description
Technical Field
[0001] This utility model belongs to the field of bottle preform production technology, and in particular relates to an injection molding device for producing beverage bottle preforms. Background Technology
[0002] When producing beverage bottles, the first step is to produce bottle preforms. The preforms are formed by injection molding, where raw materials are filled into the mold under specific temperature and pressure conditions. After injection molding, they become semi-finished products and are then blow molded into the final product.
[0003] Currently, during the injection molding production of bottle preforms, the preforms produced in the injection molding equipment are generally discharged directly into the collection box below the injection molding equipment. However, the freshly injection molded preforms are generally at a high temperature and are relatively soft. Therefore, dropping them directly from a height may cause the preforms to deform or even break when impacted, affecting the subsequent processing of the preforms and reducing the yield rate of the preforms during production.
[0004] Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an injection molding device for producing beverage bottle preforms, solving the problems mentioned in the background section. To solve the aforementioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to an injection molding device for producing beverage bottle preforms, comprising a fixed frame, a vertical injection device body fixedly mounted on the top of the fixed frame, a connecting base plate fixedly mounted on the lower end of the outer wall of the fixed frame, a rotating shaft rotatably connected to the upper end of the outer wall of the connecting base plate, a rotating base fixedly mounted on the upper end of the outer wall of the rotating shaft, and a placement frame circumferentially fixedly mounted on the upper end of the outer wall of the rotating base, wherein a buffer ring with elastic connection is provided inside the placement frame.
[0007] Furthermore, a gear one is fixedly connected to the side wall of the rotating shaft, a motor is fixedly installed on the upper end of the outer wall of the connecting base plate, and a gear two is fixedly connected to the output end of the motor, with the gear two meshing with the gear one.
[0008] Furthermore, connecting rods are fixedly installed circumferentially on the inner wall of the placement frame. All the connecting rods pass through the upper end of the outer wall of the buffer ring and are slidably connected to the buffer ring. Buffer springs are fixedly connected to the outer side of all the connecting rods and between the lower end of the outer wall of the buffer ring and the lower end of the inner wall of the placement frame.
[0009] Furthermore, a connecting frame is fixedly installed at the front end of the outer wall of the fixed frame, and a falling pipe is fixedly installed at the front end of the outer wall of the connecting frame. Air blowing pipes are symmetrically and linearly connected to the left and right sides of the outer wall of the falling pipe. Each air blowing pipe on the left and right sides is fixedly installed with a connecting pipe. An arc-shaped pipe is simultaneously connected to the rear end of the side wall of the two connecting pipes, and an air inlet pipe is connected to the middle of the rear end of the side wall of the arc-shaped pipe.
[0010] Furthermore, the middle of the upper end of the falling pipe is aligned with the middle of the discharge port of the vertical injection device body.
[0011] Furthermore, a photoelectric sensor is fixedly installed on the upper rear side of the side wall of the falling pipe, a mounting bracket is welded to the upper outer wall of the connecting base plate, the air inlet pipe passes through the mounting bracket and is fixedly connected to a solenoid valve, the input end of the solenoid valve is connected to an input pipe, and a microcontroller is fixedly installed on the upper outer wall of the mounting bracket.
[0012] Furthermore, the microcontroller is electrically connected to the photoelectric sensor and the solenoid valve.
[0013] This utility model has the following beneficial effects:
[0014] 1. When this utility model is in use, when a bottle preform falls into the falling pipe, compressed air is injected into the arc-shaped pipe, which causes the connecting pipe to blow air into the air blowing pipes on both sides. This creates an upward airflow inside the falling pipe, which slows down the bottle preform entering the falling pipe, thereby reducing the impact force on the bottle preform when it falls. At the same time, the flowing airflow can cool down the bottle preform, increasing the hardness of the freshly injection molded bottle preform.
[0015] 2. When this utility model is in use, when the preform falls into the placement frame, the tail of the preform will contact the compression buffer ring, which will drive the buffer ring to move downward along the connecting rod, so that the buffer ring compresses the buffer spring, thereby buffering the impact force generated when the tail of the preform hits the buffer ring, preventing the preform from deforming or breaking due to direct impact, and improving the yield rate of preform production.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0025] Please see Figure 1 , Figure 2 and Figure 5As shown, this utility model is an injection molding device for producing beverage bottle preforms, including a fixed frame 100. A vertical injection device body 200 is fixedly installed on the top of the fixed frame 100. A connecting base plate 300 is fixedly installed on the lower end of the outer wall of the fixed frame 100. A rotating shaft 310 is rotatably connected to the upper end of the outer wall of the connecting base plate 300. A rotating base 400 is fixedly installed on the upper end of the outer wall of the rotating shaft 310. Placement frames 500 are circumferentially fixedly installed on the upper end of the outer wall of the rotating base 400. The internal structure of the vertical injection unit 200 is equipped with a flexible buffer ring 520. The vertical injection unit body 200 can injection mold a preform 1. The injection-molded preform 1 is discharged and falls down by the vertical injection unit body 200. Connecting rods 510 are fixedly installed circumferentially on the inner wall of the placement frame 500. All connecting rods 510 pass through the upper end of the outer wall of the buffer ring 520 and are slidably connected to the buffer ring 520. All connecting rods 510 are located on the outer side and at the lower end of the outer wall of the buffer ring 520 and the inner wall of the placement frame 500. A buffer spring 530 is fixedly connected between the lower ends. The preform 1 discharged from the outlet of the vertical injection device body 200 falls into the placement frame 500. When the preform 1 falls into the placement frame 500, the tail of the preform 1 contacts the compression buffer ring 520, causing the buffer ring 520 to move downwards along the connecting rod 510. This allows the buffer ring 520 to compress the buffer spring 530, buffering the impact force when the tail of the preform 1 hits the buffer ring 520. A rotating shaft 310 is fixedly connected to the side wall of the spring. Gear 320 is connected to a motor 330 fixedly installed on the upper part of the outer wall of the base plate 300. Gear 340 is fixedly connected to the output end of the motor 330. Gear 340 meshes with gear 320. The motor 330 drives gear 340 to rotate, thereby causing gear 320 and the rotating shaft 310 to rotate, causing the rotating base plate 400 to rotate. The rotation of the rotating base plate 400 collects the preforms 1 discharged from the vertical injection device body 200 in sequence.
[0026] Among them, such as Figure 1-4As shown, a connecting frame 600 is fixedly installed on the front end of the outer wall of the fixed frame 100. A falling pipe 610 is fixedly installed on the front end of the outer wall of the connecting frame 600. Air blowing pipes 620 are symmetrically and linearly connected to the left and right sides of the outer wall of the falling pipe 610. Each air blowing pipe 620 on the left and right sides is fixedly installed with a connecting pipe 630. An arc-shaped pipe 640 is simultaneously connected to the rear end of the side wall of the two connecting pipes 630. An air inlet pipe 650 is connected to the middle of the rear end of the side wall of the arc-shaped pipe 640. When the preform 1 is injected from the vertical injection device body 20... When discharged, the preform 1 enters the drop pipe 610. Compressed air is injected into the arc-shaped pipe 640, causing the two connecting pipes 630 to blow air into the air blowing pipes 620 on both sides. This creates an upward airflow inside the drop pipe 610, which slows down the preform 1 entering the drop pipe 610. At the same time, the flowing airflow cools the preform 1. The upper middle part of the drop pipe 610 is aligned with the middle of the outlet of the vertical injection device body 200, so that the preform 1 flows out from the vertical injection device body 200. The preform 1 discharged from body 200 can accurately fall into the top of the falling pipe 610. A photoelectric sensor 700 is fixedly installed on the upper rear side of the side wall of the falling pipe 610. A mounting bracket 660 is welded to the upper outer wall of the connecting base plate 300. An air inlet pipe 650 passes through the mounting bracket 660 and is fixedly connected to a solenoid valve 710. An input pipe 670 is connected to the input end of the solenoid valve 710. A microcontroller 720 is fixedly installed on the upper outer wall of the fixing bracket 100. The microcontroller 720 is connected to the photoelectric sensor 700 and... The solenoid valve 710 is electrically connected, and the input pipe 670 is used to connect to an external air source such as an air compressor. The photoelectric sensor 700 can detect the preform 1 falling into the falling pipe 610. When a preform 1 falls into the falling pipe 610, the photoelectric sensor 700 will feed back the signal to the microcontroller 720. At this time, the microcontroller 720 opens the solenoid valve 710 to allow the compressed air in the input pipe 670 to enter the intake pipe 650 and the arc pipe 640.
[0027] A specific application of this embodiment is as follows: During use, when the preform 1 produced by injection molding in the vertical injection unit body 200 is discharged and falls, it enters the falling pipe 610. The photoelectric sensor 700 can detect the preform 1 falling into the falling pipe 610. When a preform 1 falls into the falling pipe 610, the photoelectric sensor 700 will feed back the signal to the microcontroller 720. At this time, the microcontroller 720 opens the solenoid valve 710 to allow compressed air in the input pipe 670 to enter the air inlet pipe 650 and the arc pipe 640. By injecting compressed air into the arc pipe 640, the two connecting pipes 630 can blow air into the air blowing pipes 620 on both sides, thereby forming an upward airflow inside the falling pipe 610. The airflow slows down the preform 1 entering the falling pipe 610, and at the same time, the flowing airflow cools the preform 1. Then, when the preform 1 falls from the falling pipe 610 into the placement frame 500, the tail of the preform 1 contacts the compression buffer ring 520, causing the buffer ring 520 to move downward along the connecting rod 510, so that the buffer ring 520 compresses the buffer spring 530 to buffer the impact force when the tail of the preform 1 hits the buffer ring 520. The start of the motor 330 drives the gear 2 340 to rotate, so that the gear 1 320 and the rotating shaft 310 rotate, causing the rotating base 400 to rotate. The rotation of the rotating base 400 collects the preform 1 discharged from the vertical injection device body 200 in sequence.
