Description

Technical Field

[0001] This application relates to the field of glass bottle manufacturing technology, and in particular to a glass bottle mold. Background Technology

[0002] In the glass bottle production process, the high-temperature glass material is first initially shaped using a preliminary mold, and then transferred to a final mold to be shaped into its final form through a blowing cooling zone.

[0003] When glass is blown into shape in a mold, it requires a top mold, two half molds, and a bottom mold to work together. Cooling holes are typically made in the half molds to allow cooling media to pass through and cool the glass bottle during molding. After molding, the glass bottle needs to cool rapidly. The heat dissipation rate at the two parting lines differs from other areas, causing asynchronous thermal contraction during molding. This results in tensile stress at the parting lines, and when this stress exceeds the glass's tensile strength, it can lead to microcracks. Utility Model Content

[0004] To reduce the possibility of cracks forming in glass bottles at the parting line, this application provides a glass bottle making mold.

[0005] The glass bottle making mold provided in this application adopts the following technical solution: A glass bottle mold includes two half-molds and two cooling components; the two cooling components are connected to one of the half-molds, or the two cooling components are respectively connected to the two half-molds; when the two half-molds are closed, the two cooling components are respectively located at two parting lines.

[0006] By adopting the above technical solution, a cooling component is added to the half mold. When the mold is closed, the cooling component is used to cool the parting line, thereby improving the cooling uniformity and reducing the possibility of cracks occurring at the parting line after the glass bottle is formed.

[0007] Optionally, the cooling component includes horizontal pipes and vertical pipes. Multiple horizontal pipes are provided, and the multiple horizontal pipes are arranged at intervals along the length direction of the parting line. The vertical pipes extend along the length direction of the parting line. All the horizontal pipes are connected to the vertical pipes, and the inner cavities of the multiple horizontal pipes are all connected to the inner cavities of the vertical pipes.

[0008] By adopting the above technical solution, the vertical pipe is used to cover the parting line position to ensure the cooling effect at the parting line position; multiple horizontal pipes are used to ensure the uniformity of cooling at the parting line position.

[0009] Optionally, the number of the horizontal pipes is even, and the same end of adjacent horizontal pipes is interconnected; of the two interconnected horizontal pipes, one is used for the inlet of the cooling medium and the other is used for the outlet of the cooling medium.

[0010] By adopting the above technical solution, the cooling component has multiple spaced cooling medium inlets and outlets, reducing the time interval for the cooling medium to reach various positions in the vertical pipe and further increasing the cooling uniformity of the cooling component.

[0011] Optionally, the cooling element is detachably connected to the half-mold.

[0012] By adopting the above technical solutions, it is easy to improve existing glass bottle forming molds.

[0013] Optionally, the cooling component has a first connector at its upper end and a second connector at its lower end; the first connector has a first screw hole, and a first bolt is threaded into the first screw hole; the second connector has a second screw hole, and a second bolt is threaded into the second screw hole; the distance between the first connector and the second connector is greater than the height of the half mold.

[0014] By adopting the above technical solution, when installing the cooling component on the half mold, first move the cooling component until the first connecting component is above the half mold and the second connecting component is below the half mold. Then, tighten the first bolt and the second bolt so that the end of the first bolt abuts against the upper end face of the half mold and the end of the second bolt abuts against the lower end face of the half mold, thereby fixing the cooling component.

[0015] Using the above-mentioned fixed structure, the cooling components can be installed in the half mold without modifying the existing half mold structure. The structure is simple, easy to operate, and has low modification costs.

[0016] Optionally, multiple first bolts and multiple second bolts are provided, and multiple first screw holes and multiple second screw holes are provided correspondingly.

[0018] Optionally, the end of the first bolt is provided with an anti-loosening component, the diameter of which is larger than the diameter of the bolt shank.

[0019] By adopting the above technical solution, the first bolt is prevented from coming out of the first screw hole, reducing the risk of the first bolt being lost.

[0020] Optionally, the outer wall of the anti-detachment component is fitted with a flexible sleeve.

[0021] By adopting the above technical solution, the damage to the half mold caused by the first bolt abutting against the half mold is reduced.

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application mainly adopts a solution of setting a cooling component 2 at the parting line of the half mold 1, which achieves the effect of balancing the heat dissipation rate of the parting line area and other areas, and avoiding the occurrence of micro-cracks in the glass bottle. The following is a further detailed description of this application.

[0030] The glass bottle mold provided in this application includes two half molds 1 and two cooling components 2. The two cooling components 2 are connected to one of the half molds 1, or the two cooling components 2 are respectively connected to the two half molds 1. When the two half molds 1 are closed, the two cooling components 2 are respectively located at the two mold parting lines.

[0031] In this embodiment, both cooling components 2 are connected to the same half mold 1 to ensure the structural symmetry of the two half molds 1 and to facilitate the introduction of cooling medium.

[0032] This design utilizes cooling component 2 to specifically cool the parting line area, balancing the heat dissipation rate of this area with other areas, avoiding the formation of micro-cracks due to tensile stress caused by "asynchronous thermal contraction", and improving the quality of the glass bottle.

[0033] Specifically, the cooling component 2 includes horizontal pipes 21 and vertical pipes 22. Multiple horizontal pipes 21 are provided, and the vertical pipes 22 extend along the length of the parting line. All horizontal pipes 21 are connected to the vertical pipes 22, and the inner cavities of the multiple horizontal pipes 21 are all connected to the inner cavities of the vertical pipes 22. The horizontal pipes 21 are tubular structures, and their material can be copper or aluminum alloy. Copper has good thermal conductivity and can quickly transfer heat, while aluminum alloy has the advantages of being lightweight and corrosion-resistant. The vertical pipes 22 are also tubular, with a similar structure to the horizontal pipes 21, and their material can also be copper or aluminum alloy. The connection between the horizontal pipes 21 and the vertical pipes 22 can be welded. Welding ensures the sealing and connection strength between the two, allowing the cooling medium to flow smoothly within their respective cavities. Multiple horizontal pipes 21 are arranged at intervals along the length of the parting line, allowing the cooling medium to be evenly distributed in the parting line area for more effective cooling. For example, the horizontal pipes 21 can be arranged at equal intervals, or the spacing can be adjusted according to the heat dissipation requirements at different locations along the parting line.

[0034] The combination logic of horizontal pipes 21 and vertical pipes 22 is that the vertical pipes 22 deliver the cooling medium to each horizontal pipe 21, and then the horizontal pipes 21 distribute the cooling medium to different positions along the parting line, thereby improving the uniformity of cooling. Because multiple horizontal pipes 21 can simultaneously cool the parting line area, it avoids localized insufficient or excessive cooling. The combined effect is that the temperature in the parting line area decreases more uniformly, and the heat dissipation rate is closer to that of other areas, thereby reducing the generation of tensile stress.

[0035] Specifically, the number of horizontal pipes 21 is even, and adjacent horizontal pipes 21 are interconnected at the same end. Of the two interconnected horizontal pipes 21, one is used for the inflow of cooling medium, and the other is used for the outflow of cooling medium. This creates a cooling medium circulation loop using adjacent horizontal pipes 21, improving the utilization rate of the cooling medium. For example, the horizontal pipes 21 can be connected at the same end using elbows, and the elbows can be made of the same material as the horizontal pipes 21. When the cooling medium flows in from one horizontal pipe 21, passes through the connection point with the adjacent horizontal pipe 21, and then flows out from the other horizontal pipe 21, forming a loop that continuously removes heat from the parting line area.

[0036] The combination logic of an even number of adjacent and connected horizontal pipes 21 creates a circulating cooling path for the cooling medium in the parting line area through alternating inflow and outflow. This combination ensures smoother flow of the cooling medium within the horizontal pipes 21, improving the cooling effect. The combined effect is to make the cooling in the parting line area more stable and efficient, further balancing the heat dissipation rate with other areas.

[0037] Furthermore, the cooling component 2 is detachably connected to the mold half 1. This allows for the installation, removal, and replacement of the cooling component 2, improving mold maintenance efficiency and enabling direct improvements to the existing mold half 1.

[0038] Specifically, the cooling component 2 has a first connecting member 23 at its upper end and a second connecting member 24 at its lower end. The first connecting member 23 has a first threaded hole 231, to which a first bolt 25 is threadedly connected. The second connecting member 24 has a second threaded hole 241, to which a second bolt 26 is threadedly connected. The distance between the first connecting member 23 and the second connecting member 24 is greater than the height of the half-mold 1. The first connecting member 23 and the second connecting member 24 are typically block structures, made of steel, possessing a certain strength and hardness. The first bolt 25 and the second bolt 26 are used to fix the cooling component 2 to the half-mold 1; the threaded connection facilitates installation and disassembly. The first connecting member 23 and the second connecting member 24 are located at the upper and lower ends of the cooling component 2, respectively, and are connected to the half-mold 1 by bolts, ensuring the stability of the connection between the cooling component 2 and the half-mold 1.

[0039] The combination logic of the first connector 23, the second connector 24, the first bolt 25, and the second bolt 26 is to fix the cooling component 2 to the half-mold 1 through the engagement of the bolts and threaded holes. This combination method utilizes the detachability of the threaded connection, making it convenient to adjust or replace the cooling component 2 when needed. The combined effect is that the cooling component 2 can be firmly installed on the half-mold 1 without altering the existing structure of the half-mold 1.

[0040] In this embodiment, multiple first bolts 25 and multiple second bolts 26 are provided, and multiple first screw holes 231 and multiple second screw holes 241 are provided correspondingly. The provision of multiple bolts and screw holes can increase the stability of the connection and prevent the cooling component 2 from loosening during use.

[0041] Furthermore, an anti-loosening element 27 is provided at the end of the first bolt 25. The diameter of the anti-loosening element 27 is larger than the diameter of the bolt shank of the first bolt 25. The anti-loosening element 27 can be a circular washer, and the material can be rubber or plastic. The anti-loosening element 27 can prevent the first bolt 25 from coming out of the bolt hole during use, ensuring the reliability of the connection.

[0042] When the anti-detachment component 27 is made of rigid material, a flexible sleeve 28 is provided on the outer wall of the anti-detachment component 27. The flexible sleeve 28 can be a silicone sleeve, which can play a role in buffering and protection, and reduce the wear between the anti-detachment component 27 and other components.

[0043] The implementation principle of this embodiment is as follows: The glass bottle mold utilizes a cooling element 2 at the parting line for targeted cooling of the parting line area. By combining horizontal pipes 21 and vertical pipes 22, along with a circulating cooling medium, more uniform and efficient cooling of the parting line area is achieved. Simultaneously, the detachable connection between the cooling element 2 and the half-mold 1, along with related connection structure design, improves mold maintenance efficiency and connection stability. Compared to existing technologies, this effectively balances the heat dissipation rate between the parting line area and other areas, preventing the generation of micro-cracks and improving the quality and production efficiency of the glass bottles.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
