Description
Technical Field
[0001] The present application relates to the technical field of glass production, and in particular to a mold for manufacturing glass bottles. Background Art
[0002] In the process of producing glass bottle products by the row machine, the primary mold and the final mold (both are steel molds) are needed. The primary mold is used to form the bottle mouth and the initial blank of the product; then the initial blank of the product is transferred to the final mold for further blowing, and the final shape of the product is formed according to the shape of the final mold cavity.
[0003] Reference Figure 1 In order to ensure the continuous production of the machine with high efficiency, various cooling methods are usually applied to the mold 1 to shorten the time of each mold closing and pressure holding and improve production efficiency. One of the cooling methods is to drill a plurality of vertical cooling holes 32 on the mold 1 and blow cold air into the vertical cooling holes 32, thereby accelerating the cooling speed of the glass bottles in the chamber 11.
[0004] Reference Figure 1 and Figure 2 In the prior art, a convex pattern 21 (commonly a trademark or exclusive pattern of a product manufacturer) is often provided on the shoulder of the glass bottle 2, and a pattern groove 33 for accommodating the convex pattern 21 is provided on the inner wall of the mold 1. Since the thickness of the convex pattern 21 is relatively small, and compared with the main structure of the glass bottle 2, the convex pattern 21 is closer to the vertical cooling hole 32, so that the convex pattern 21 on the shoulder of the glass bottle 2 is cracked due to excessive cooling, thereby affecting the quality of the glass product before delivery.
[0005] In order to improve the cracking phenomenon of the raised pattern, we tried to block some of the vertical cooling holes outside the raised pattern. However, due to uneven cooling, the glass bottle was slightly deformed and there was a gap with the designed standard size. Utility Model Content

[0015] Optionally, the height of the pattern groove is 13.8 mm, and the height of the insulation tube is 45 mm.

[0022] By adopting the above technical solution, the limiting ring is used to limit the position of the insulation tube in the first vertical cooling hole, so that the insulation tube can be accurately installed at the specified position, thereby improving the protection effect of the insulation tube on the raised pattern.
[0023] Optionally, along the moving direction of the cold air in the first vertical cooling hole, the distance from the limiting ring to the inner side wall of the first vertical cooling hole increases gradually.
[0024] By adopting the above technical solution, the distance from the limiting ring to the inner wall of the first vertical cooling hole increases gradually, which is beneficial to the circulation of cold air in the first vertical cooling hole, so that the cold air can pass through the insulation pipe smoothly.
[0025] In summary, the present application includes at least one of the following beneficial technical effects:
[0026] An insulation tube is arranged in the first vertical cooling hole. The thermal conductivity of the insulation tube is smaller than that of the half mold, which is equivalent to setting an obstacle on the heat conduction path between the cold air and the raised pattern, thereby slowing down the cooling speed of the cold air on the raised pattern and reducing the occurrence of cracks in the raised pattern due to over-rapid cooling.
[0027] When the height ratio of the heat insulation tube to the pattern groove is in the range of 3-4, while ensuring the cooling protection effect of the heat insulation tube on the convex pattern, the influence of the heat insulation tube on the overall cooling effect of the glass bottle is reduced, so that the cold air in the vertical cooling tube can evenly cool the glass bottle;

DETAILED DESCRIPTION
[0037] The following is combined with Figure 2-7 This application is described in further detail.
[0038] Example 1
[0039] The present application embodiment discloses a mold for manufacturing a glass bottle. Figure 2 The shoulder of the glass bottle 2 is often provided with a raised pattern 21 (commonly a trademark, exclusive pattern, etc. of the product manufacturer).
[0040] Reference Figure 3 and Figure 4 The mold for manufacturing a glass bottle includes a symmetrically arranged half mold 3 and a hollow insulation tube 4.
[0041] Reference Figure 3 and Figure 4 , the two half molds 3 are combined to form a cavity 31, and the cavity 31 is used to accommodate the glass bottle 2. A plurality of vertical cooling holes 32 are vertically penetrated through the half mold 3, and the plurality of vertical cooling holes 32 are arranged around the cavity 31. The vertical cooling holes 32 are externally connected to a cooling air device, and the vertical cooling holes 32 are used to supply cooling air. In this embodiment, the vertical cooling holes 32 are surrounded into an inner circle and an outer circle, and the inner circle is arranged on one side of the outer circle close to the cavity 31; the vertical cooling holes 32 are surrounded into an inner circle and an outer circle, thereby increasing the cooling speed of the vertical cooling holes 32 on the glass bottle 2. In other embodiments, the vertical cooling holes 32 can be surrounded in one circle, three circles, etc.
[0042] Reference Figure 4 and Figure 5 The inner side wall of the half mold 3 is provided with a pattern groove 33 for accommodating the raised pattern 21.
[0043] Reference Figure 3 and Figure 4 The vertical cooling holes 32 include a first vertical cooling hole 321 and a second vertical cooling hole 322. The first vertical cooling hole 321 is arranged on the inner circle of the outer periphery of the pattern groove 33, and the second vertical cooling hole 322 is arranged in other areas of the half mold 3. Cold air flows through the first vertical cooling hole 321 and the second vertical cooling hole 322 of the half mold 3, thereby accelerating the cooling speed of the glass bottle 2 in the cavity 31 by utilizing the heat conduction principle. In this embodiment, the cold air is arranged in the vertical cooling pipe from top to bottom.
[0044] Reference Figure 4 and Figure 5 , the insulation tube 4 is inserted into the first vertical cooling hole 321, and the outer periphery of the insulation tube 4 is fixedly abutted against the inner wall of the first vertical cooling hole 321. The thermal conductivity of the insulation tube 4 is less than that of the half mold 3, and the insulation tube 4 is used to prevent the cold air from cooling the raised pattern 21. The insulation tube 4 is equivalent to setting an obstacle on the heat conduction path between the cold air and the raised pattern 21, thereby slowing down the cooling speed of the cold air on the raised pattern 21, and reducing the occurrence of cracks in the raised pattern 21 due to excessive cooling. At the same time, it can ensure that the cold air in the first vertical cooling hole 32 and the second vertical cooling hole 322 evenly cools other parts of the glass bottle 2, reduces the structural deformation of the glass bottle 2 caused by uneven cooling, maintains the roundness of the glass bottle 2, and improves the factory quality of the glass bottle 2.
[0045] In this embodiment, the insulation tube 4 is a hollow copper tube. The thermal conductivity of the copper tube is less than that of the half mold 3, which can achieve the protective effect of the embossed pattern. At the same time, the copper tube is easy to process and has a certain rigidity, so it is convenient for the staff to plug and fix it in the geothermal vertical cooling hole 32.
[0046] Reference Figure 5, the pattern groove 33 is arranged between the two ends of the heat insulation tube 4, and the height difference from the end of the heat insulation tube 4 to the pattern groove 33 is the same; and the height ratio of the heat insulation tube 4 to the pattern groove 33 is 3-4. When the height ratio of the heat insulation tube 4 to the pattern groove 33 is in the range of 3-4, while ensuring the cooling protection effect of the heat insulation tube 4 on the convex pattern; the influence of the heat insulation tube 4 on the overall cooling effect of the glass bottle 2 can be reduced, so that the cold air in the vertical cooling tube can evenly cool the glass bottle 2 to maintain the roundness of the glass bottle 2.
[0047] In this embodiment, the height of the pattern groove 33 is 13.8 mm, and the height of the insulation tube 4 is 45 mm. Example 2
[0048] The difference between this embodiment 2 and embodiment 1 is that:
[0049] The mold further includes a limit ring 5, which is arranged in the first vertical cooling hole 321 and is fixedly connected to the half mold 3; the limit ring 5 is arranged on the insertion path of the insulation tube 4, and the limit ring 5 is used to limit the displacement of the insulation tube 4. In this embodiment, the limit ring is integrally formed with the half mold 3. At the same time, along the moving direction of the cold air in the first vertical cooling hole 321, the distance from the limit ring 5 to the inner side wall of the first vertical cooling hole 321 increases. The limit ring 5 is used to limit the position of the insulation tube 4 in the first vertical cooling hole 321, so that the insulation tube 4 is accurately installed at the specified position, and the protection effect of the insulation tube 4 on the raised pattern 21 is improved. The distance from the limit ring 5 to the inner side wall of the first vertical cooling hole 321 increases, which is conducive to the circulation of cold air in the first vertical cooling hole 321, so that the cold air passes through the insulation tube 4 smoothly.
[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
