Description

Technical Field

[0001] This utility model relates to the field of glass bottle production, and in particular to a bottom mold cooling structure for making glass bottles. Background Technology

[0002] Bottom molds are used to shape the bottom of glass bottles. With changing production needs, the glass bottle industry has put forward more and higher requirements for the shape of glass bottles, especially for the shape of the bottle bottom. For example, the bottom of a wine bottle needs to be made into a concave shape, and the concavity is relatively deep. This design not only helps the stability of the bottle, but also promotes the contact between the wine and air when pouring, enhances the oxidation process, and thus improves the flavor of the wine.

[0003] The bottom mold needs to be made with a matching molding protrusion for the concave design. However, because the molding protrusion of the bottom mold is relatively high, the contact area between the bottom mold and the concave glass of the glass bottle is large when molding the glass bottle. This large contact area leads to high heat transfer efficiency, causing the temperature of the molding protrusion to rise rapidly. The high temperature increases the adhesion between the molding protrusion of the bottom mold and the bottom of the glass bottle, making demolding difficult. This not only reduces production efficiency but may also cause product scrap and mold damage.

[0004] To address the issue of high temperatures at the forming convex part of the mold base, a cooling core is typically installed inside the mold base. The mold base and cooling core are mounted on a cooling plate, which has cooling air channels inside. A cooling port is located at the top of the cooling core, connecting the cooling air channels and the cooling port. This allows the cooling core to be inserted into the forming convex part, where the cooling port provides airflow to cool it. However, because the location of the cooling port and the forming convex part cannot be observed when the cooling core is inserted, if the core is inserted too shallowly, it cannot reach the interior of the forming convex part sufficiently, resulting in uneven cooling and the forming convex part remaining overheated. If the core is inserted too deeply, while it ensures cooling of the bottom of the forming convex part, excessive insertion can lead to over-cooling, causing uneven cooling of the entire mold and potentially stress cracks at the bottom of the glass bottle. Therefore, the insertion depth of the cooling core is crucial, but currently there is no structure that allows for intuitive adjustment of the cooling core depth, making adjustment inconvenient. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a bottom mold cooling structure for manufacturing glass bottles. The purpose is to solve the technical problem that there is currently no structure that allows for intuitive adjustment of the cooling core depth, which makes the adjustment of the cooling core inconvenient.

[0012] By setting a second positioning pin and socket structure between the mounting base and the adjusting shim, the connection between the adjusting shim and the mounting base can be made more secure, preventing the adjusting shim from shifting during operation; at the same time, this structure cooperates with the first positioning pin to ensure the precise positioning of the cooling core in the entire cooling system.

[0013] Furthermore, in this application, the bottom mold body has adjustment holes on both sides that communicate with the mounting cavity, and adjustment bolts are threaded into the adjustment holes. The adjustment bolts on both sides of the bottom mold body abut against the two sides of the cooling core, respectively.

[0015] Furthermore, in this application, the bottom mold body has a first air outlet on both sides, and the first air outlet is connected to the mounting cavity.

[0016] Furthermore, in this application, the cooling core has multiple second air outlets inside, and the second air outlets are connected to the mounting cavity.

[0017] Furthermore, in this application, the bottom of the cooling core is provided with a plurality of first air outlet channels, which are respectively connected to a plurality of second air outlet holes.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Reference Figures 1-5In some specific embodiments, a bottom mold cooling structure for manufacturing glass bottles includes a cooling plate 1, a bottom mold body 2 on the top of the cooling plate 1, a forming protrusion 4 on the top of the bottom mold body 2, a cooling cavity 8 inside the forming protrusion 4, an installation cavity 7 communicating with the cooling cavity 8 inside the bottom mold body 2, a cooling core 9 slidably connected inside the installation cavity 7, a cooling nozzle 11 on the top of the cooling core 9, the cooling nozzle 11 being located inside the cooling cavity 8, and a cooling port 22 on the top of the cooling nozzle 11 communicating with the cooling cavity 8. The bottom of the cooling core 9 is provided with an air inlet slot 10 that connects to the cooling port 22, and also includes an adjusting shim 15. The interior of the cooling plate 1 is provided with a mounting base 21, and the top of the mounting base 21 is provided with an air inlet pipe 18. The interior of the air inlet pipe 18 is provided with a cooling air duct 19. The interior of the adjusting shim 15 is provided with a sleeve groove 17. The air inlet pipe 18 passes through the sleeve groove 17 so that the air inlet pipe 18 is inserted into the air inlet slot 10. The cooling air duct 19 is connected to the air inlet slot 10. The adjusting shim 15 is located on the top of the mounting base 21, and the bottom of the cooling core 9 abuts against one side of the adjusting shim 15.

[0033] Through the above technical solution, the adjusting shim 15 is installed between the cooling core 9 and the mounting base 21. When the cooling core 9 is placed on a thicker adjusting shim 15, the adjusting shim 15 will occupy most of the space in the mounting cavity 7. Therefore, the adjusting shim 15 will force the cooling core 9 to be inserted into the mounting cavity 7 to a deeper depth. When the cooling core 9 is placed on a thinner adjusting shim 15, the adjusting shim 15 will occupy a small portion of the space in the mounting cavity 7. Therefore, the adjusting shim 15 will force the cooling core 9 to be inserted into the mounting cavity 7 to a shallower depth. Thus, by replacing adjusting shims 15 of different thicknesses, the insertion depth of the cooling core 9 can be adjusted. Furthermore, by observing the thickness of the adjusting shim 15, the insertion depth of the cooling nozzle 11 can be intuitively understood, so as to test whether the insertion depth of the cooling nozzle 11 achieves the best cooling effect on the cooling cavity 8.

[0034] It should be noted that the length of the mounting cavity 7 needs to be longer than the length of the cooling core 9 so that the cooling core 9 can be adjusted up and down within the mounting cavity 7; the cooling air duct 19 is connected to an external air source.

[0035] In addition, the adjusting shim 15 can be made of metal, engineering plastic or composite material, and the appropriate material can be selected according to the temperature and strength requirements of the working environment; the adjusting shim 15 can be designed with standardized modules of different thicknesses, such as marked with 2mm, 4mm, 6mm, etc., to facilitate quick identification and replacement; the adjusting shim 15 can be designed as a telescopic structure or adjust the thickness by stacking washers to further improve the adjustment accuracy and flexibility; the adjusting shim 15 can also be designed as an electrically or pneumatically adjustable structure, and the insertion depth of the cooling core 9 can be adjusted in real time through the control system to adapt to different production needs.

[0036] Reference Figures 2-3 In some specific embodiments, the top of the adjusting shim 15 is provided with a plurality of first positioning pins 13, and the bottom of the cooling core 9 is provided with a plurality of first positioning holes 12, and the plurality of first positioning pins 13 are respectively inserted into the plurality of first positioning holes 12.

[0037] Through the above technical solution, by setting the insertion structure of the first positioning pin 13 and the first positioning hole 12, the position of the cooling core 9 in the installation cavity 7 can be accurately positioned, preventing the cooling core 9 from shifting due to vibration or airflow during operation. At the same time, the pin and hole structure facilitates quick installation and disassembly, improving the operating efficiency of the cooling structure.

[0038] In addition, the shape of the first positioning hole 12 can be adjusted to be circular, elliptical or square as needed to adapt to different production and processing requirements.

[0039] Reference Figures 2-3 In some specific embodiments, the top of the mounting base 21 is provided with a plurality of second positioning pins 16, and the bottom of the adjusting pad 15 is provided with a plurality of second positioning holes 14, and the plurality of second positioning pins 16 are respectively inserted into the plurality of second positioning holes 14.

[0040] By using the above technical solution, by setting a second positioning pin 16 and a socket structure between the mounting base 21 and the adjusting shim 15, the connection between the adjusting shim 15 and the mounting base 21 can be made more stable, preventing the adjusting shim 15 from shifting during operation; at the same time, this structure cooperates with the first positioning pin 13 to ensure the precise positioning of the cooling core 9 in the entire cooling system.

[0041] In addition, the second positioning pin 16 can be connected to the adjusting shim 15 by a threaded connection, providing stronger fixing force and suitable for high vibration conditions; the adjusting shim 15 can be designed as modular, and shims of different thicknesses can be replaced to meet various cooling depth adjustment needs.

[0042] Reference Figures 3-5 In some specific embodiments, adjustment holes 23 are provided on both sides of the bottom mold body 2 to connect the mounting cavity 7. Adjustment bolts 24 are threaded into the adjustment holes 23, and the adjustment bolts 24 on both sides of the bottom mold body 2 respectively abut against the two sides of the cooling core 9.

[0043] Through the above technical solution, by adjusting the contact between the adjusting bolt 24 and both sides of the cooling core 9, the cooling core 9 can be temporarily fixed by using the radial support force provided by the adjusting bolt 24 after it has been slidably adjusted to the target depth. This design prevents the cooling core 9 from shifting due to operational vibration or wind pressure during depth adjustment. The threaded connection structure of the adjusting bolt 24 ensures its stability and can be locked and released by a simple rotation action, which facilitates further fine-tuning of the position of the cooling core 9 before subsequent fixing.

[0044] In addition, the adjusting bolt 24 can be replaced with a quick-release clamp structure to more quickly complete the temporary fixation of the cooling core 9; the adjusting bolt 24 can adopt an anti-slip design, such as adding texture to the bolt head, or designing it as a knob with a handle for easy manual operation; it can be replaced with an electric or pneumatic structure to automatically adjust the position of the cooling core 9 and fix it through the control system, thereby improving operating efficiency and automation level.

[0045] Reference Figure 3 In some specific embodiments, a first fixing hole 26 is provided inside the mounting cavity 7, and a second fixing hole 27 is provided at the bottom of the cooling core 9. A fixing bolt 28 is inserted into the second fixing hole 27, and the fixing bolt 28 is threadedly engaged with the first fixing hole 26.

[0046] Through the above technical solution, by setting the first fixing hole 26 and the second fixing hole 27 at the bottom of the mounting cavity 7 and the cooling core 9 respectively, and using fixing bolts 28 to connect the two with threaded engagement, the cooling core 9 can be reliably fixed in the formal production stage. This design ensures that the cooling core 9 will not shift its position due to factors such as vibration, airflow or thermal expansion and contraction during operation, thereby maintaining the stability of the insertion depth and jet effect of the cooling core 9.

[0047] Reference Figures 3-5 In some specific embodiments, the bottom mold body 2 has a first air outlet 25 on both sides, and the first air outlet 25 is connected to the mounting cavity 7.

[0048] Through the above technical solution, the first air outlet 25 is connected to the mounting cavity 7, so that after the cooling gas cools the cooling cavity 8, it provides an outlet for the cooling gas, ensuring smooth airflow circulation in the cooling cavity 8 and the mounting cavity 7, thereby maintaining the efficient operation of the cooling system.

[0049] Reference Figures 2-5 In some specific embodiments, the cooling core 9 has multiple second air outlets 29 inside, and the second air outlets 29 are connected to the mounting cavity 7.

[0050] Through the above technical solution, the second air outlet 29 is distributed inside the cooling core 9, so that the cooling gas can cover all areas of the cooling core 9, ensuring that the overall temperature of the cooling core 9 is uniform. At the same time, the setting of the second air outlet 29 enhances the flow of cooling air in the cooling core 9 and improves the heat dissipation efficiency of the cooling system.

[0051] Reference Figures 3-5 In some specific embodiments, the bottom of the cooling core 9 is provided with a plurality of first air outlet channels 30, and the plurality of first air outlet channels 30 are respectively connected to a plurality of second air outlet holes 29. The bottom of the bottom mold body 2 is provided with a plurality of second air outlet channels 31, one end of the plurality of second air outlet channels 31 is respectively connected to a plurality of first air outlet channels 30, and the other end of the second air outlet channels 31 is connected to the outside.

[0052] With the above technical solution, when the cooling gas is discharged from the second air outlet 29, the cooling gas enters the second air outlet 31 of the bottom mold body 2 through the first air outlet 30, and then is discharged from the outlet of the second air outlet 31. Even if the bottom mold body 2 is placed on the cooling plate 1 or the cooling core 9 is inserted into the mounting base 21, the connectivity of the channel ensures the smooth flow of air, thereby avoiding the stagnation of cooling gas due to structural obstruction, ensuring smooth exhaust and stable cooling effect.

[0053] Reference Figures 1-5 In some specific embodiments, the bottom mold body 2 has multiple sets of vertical cooling holes 32 inside, which are connected to the external mold. The cooling plate 1 has multiple air inlet slots 20 inside, which are connected to multiple sets of vertical cooling holes 32 respectively.

[0054] Through the above technical solution, by setting a vertical cooling hole 32 inside the bottom mold body 2 and setting a corresponding air inlet groove 20 inside the cooling plate 1, when the external cooling device sprays air onto the air inlet groove 20, the cooling gas can flow vertically and enter the interior of the external mold from the vertical cooling hole 32. This design allows the cooling airflow to cover the longitudinal area of ​​the mold, effectively enhancing the vertical cooling effect.

[0055] Reference Figures 1-4 In some specific embodiments, the top of the bottom mold body 2 is provided with a molding seat 3, the top of the molding seat 3 is provided with a molding cavity 5, the molding protrusion 4 is located inside the molding cavity 5, the cooling cavity 8 passes through the bottom of the molding seat 3, so that the cooling cavity 8 is connected to the mounting cavity 7, and the interior of the molding cavity 5 is provided with multiple anti-slip molding recesses 6.

[0056] Through the above technical solution, the forming cavity 5 and the forming convex 4 are designed to form a specific shape at the bottom of the glass bottle. The anti-slip forming concave part 6 inside the forming cavity 5 provides a certain adhesion and support for the glass during the bottom forming process, effectively preventing forming deviation caused by the fluidity of the glass. At the same time, the anti-slip forming concave part 6 can increase the friction between the forming convex 4 and the glass, ensuring the accuracy and consistency of the bottom shape of the glass bottle.
