Technical Field
[0001] This utility model relates to the field of glass bottle processing technology, and more specifically, to a demolding device for glass bottle processing. Background Technology
[0002] Glass bottles are traditional beverage packaging containers, and glass is also a packaging material with a long history. Despite the influx of many other packaging materials into the market, glass containers still hold an important position in beverage packaging, which is inseparable from their unique packaging characteristics that other materials cannot replace.
[0003] In glass bottle processing, demolding devices are typically used to remove the glass bottle from the mold during the molding process, reducing downtime during production. Currently, glass bottle processing mostly uses blow molding methods, with mechanical blowing being the most common, such as blow-to-blow, rotary blow, belt blow, and press blow. Regardless of the method, when demolding the glass bottle, the temperature difference between the inside and outside may cause problems such as difficulty in removing the bottle or incomplete demolding, ultimately leading to defective products. Utility Model Content
[0004] The purpose of this invention is to provide a demolding device for glass bottle processing. After the glass bottle is blown into shape, it cools the left and right mold cavities to prevent the glass bottle, especially the bottom of the glass bottle, from sticking to the bottom mold base, thereby improving the demolding quality of the glass bottle product.
[0005] The embodiments of this utility model are achieved through the following technical solutions:
[0006] A demolding device for glass bottle processing includes a bottom mold base and a left mold and a right mold disposed above the bottom mold base.

[0007] A sliding mechanism is provided between the left mold and the right mold, which can drive the left mold and the right mold to slide relative to each other or opposite to each other along the bottom mold base;
[0008] The inner wall of the left mold near the left mold cavity and the inner wall of the right mold near the right mold cavity are both provided with interlayer channels. A connecting seat is provided on the bottom mold base, and several connecting channels are provided in the connecting seat. The connecting channels are connected to the interlayer channels.
[0009] Furthermore, the sliding mechanism includes a pair of sliding blocks symmetrically arranged at the bottom of the left mold and the right mold, and a positive and negative lead screw arranged laterally on the bottom mold base; the pair of sliding blocks are respectively threaded to the two threaded sections of the positive and negative lead screw; one end of the positive and negative lead screw is connected to a drive motor.
[0010] Furthermore, the sliding mechanism also includes a positioning block disposed at the bottom of the sliding block, and a positioning rod is disposed laterally inside the bottom mold base. The positioning rod is located directly below the positive and negative lead screws, and the positioning block is movably sleeved on the positioning rod and can slide laterally along the positioning rod.
[0011] Furthermore, the sliding mechanism is provided in pairs and is symmetrically arranged along the center line of the bottom mold base.
[0012] Furthermore, the connecting channel includes a first channel arranged laterally, which is connected to the interlayer channels in the left mold cavity and the right mold cavity respectively.
[0013] Furthermore, the bottom of both the left and right mold cavities has an upwardly curved arc segment, and the top of the connecting seat is arc-shaped and fits into the bottom of the left and right mold cavities;

[0018] In use, the left and right molds are fastened to the bottom mold base, forming a molding cavity with the left and right mold cavities and the bottom mold base. A robotic arm places the glass preform into the molding cavity, and then an external blowing device (such as an air compressor) blows air into the glass preform to form it, thus shaping the glass preform into a deep-bottomed glass bottle. After the glass bottle is formed, an external air or water supply device supplies cooling water or cold air into the connecting channel. The cooling water or cold air is supplied into the interlayer channel through the connecting channel, thereby cooling the left and right mold cavities and preventing the glass bottle, especially the bottom, from sticking to the bottom mold base. Then, a sliding mechanism drives the left and right molds to slide back to back along the bottom mold base, thereby opening the left and right molds. At this point, the external robotic arm can be used to remove the glass bottle, thus completing the demolding of the glass bottle. Attached Figure Description

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0024] Example 1
[0025] A demolding device for glass bottle processing includes a bottom mold base 7 and a left mold 1 and a right mold 6 disposed above the bottom mold base 7. The left mold 1 has a left mold cavity 4 on its inner sidewall, and the right mold 6 has a right mold cavity 5 on its inner sidewall. The left mold cavity 4 and the right mold cavity 5 can be tightly fastened to form the shape of a glass bottle. The left mold 1 and the right mold 6 can be fastened to the bottom mold base 7.
[0026] A sliding mechanism is provided between the left mold 1 and the right mold 6, which can drive the left mold 1 and the right mold 6 to slide relative to or opposite to each other along the bottom mold base 7.
[0027] The inner wall of the left mold 1 near the left mold cavity 4 and the inner wall of the right mold 6 near the right mold cavity 5 are both provided with interlayer channels 3. The bottom mold base 7 is provided with a connecting seat 13, and the connecting seat 13 is provided with several connecting channels, which are connected to the interlayer channels 3.
[0028] Working Principle: In use, the left mold 1 and right mold 6 are fastened to the bottom mold base 7. The left mold cavity 4, right mold cavity 5, and bottom mold base 7 are fastened together to form a molding cavity. A robotic arm places the glass blank into the molding cavity, and then an external blowing device (such as an air compressor) blows air into the glass blank in the molding cavity to form it, thereby shaping the glass blank into a glass bottle with a deep concave bottom. After the glass bottle is formed, an external air or water supply device is used to introduce cooling water or cold air into the connecting channel. The cooling water or cold air is supplied into the interlayer channel 3 through the connecting channel, thereby cooling the left mold cavity 4 and right mold cavity 5 and preventing the glass bottle, especially the bottom of the glass bottle, from sticking to the bottom mold base 7. Then, a sliding mechanism drives the left mold 1 and right mold 6 to slide back and forth along the bottom mold base 7, thereby opening the left mold 1 and right mold 6. At this time, the external robotic arm can be used to clamp out the glass bottle, thus completing the demolding of the glass bottle. Additionally, it should be noted that the cooling water or cold air blown into the interlayer channel 3 is discharged through the top of the interlayer channel 3 after heat exchange.
[0029] In this embodiment, the sliding mechanism includes a pair of sliding blocks 10 symmetrically arranged at the bottom of the left mold 1 and the right mold 6, and a positive and negative lead screw 9 arranged laterally on the bottom mold base 7; the pair of sliding blocks 10 are respectively threaded to the two threaded sections of the positive and negative lead screw 9; one end of the positive and negative lead screw 9 is connected to a drive motor 8; the sliding mechanism also includes a positioning block 12 arranged at the bottom of the sliding block 10, and a positioning rod 11 is arranged laterally inside the bottom mold base 7. The positioning rod 11 is located directly below the positive and negative lead screw 9, and the positioning block 12 is movably sleeved on the positioning rod 11 and can slide laterally along the positioning rod 11.
[0030] By starting the drive motor 8, the positive and negative lead screws 9 can be rotated, which in turn drives a pair of sliding blocks 10 to move along the positive and negative lead screws 9. Since the bottom of the sliding block 10 is provided with a positioning block 12, and the positioning block 12 is sleeved on the positioning rod 11 at the bottom, the positive and negative lead screws 9 can rotate at the same time, causing the sliding block 10 to slide relative to or away from the positive and negative lead screws 9. At the same time, the positioning block 12 slides relative to or away from the positioning rod 11, thereby separating the left mold 1 and the right mold 6, which facilitates the demolding of the glass bottle.
[0031] In this embodiment, a pair of sliding mechanisms are provided and symmetrically arranged along the center line of the bottom mold base 7; this allows for more stable control of the movement of the left mold 1 and the right mold 6, and provides better support.
[0032] In this embodiment, the connecting channel includes a first channel 14 arranged laterally, which is connected to the interlayer channel 3 in the left mold cavity 4 and the right mold cavity 5 respectively; this allows cooling water or cold air to be better introduced into the interlayer channel 3, thereby cooling the left mold 1 and the right mold 6 and facilitating the demolding of the glass bottle.
[0033] In this embodiment, the bottom center of both the left mold cavity 4 and the right mold cavity 5 has an upwardly curved arc segment, and the two arc segments form the deep concave bottom of the glass bottle; and the top of the connecting seat 13 is arc-shaped and fits with the bottom of the left mold cavity 4 and the right mold cavity 5; the connecting channel also includes a pair of second channels 15 arranged obliquely; one end of the pair of second channels 15 is connected to the interlayer channel 3 in the arc segment of the left mold cavity 4 and the right mold cavity 5 respectively, and the other end is connected to the first channel 14; it should also be noted that only a pair of second channels 15 arranged obliquely can be provided, and the second channels 15 are connected to an external air supply or water supply device; the main purpose is that by the pair of second channels 15 arranged obliquely, cooling water or cold air can be ensured to flow from the bottom to both sides first, ensuring the cooling effect, especially the cooling effect on the deep concave bottom of the glass bottle, and ensuring the demolding quality of the glass bottle.
[0034] In this embodiment, a baffle plate 2 is provided in the interlayer channel 3, which can extend the flow path and flow time of cooling water or cold air, and improve the flow to the left mold cavity 4 and the right mold cavity 5. In addition, the structure and arrangement of the baffle plate 2 are mature technologies in the prior art, and will not be described in detail here.
[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
