[0019] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1~Figure 3 , the utility model embodiment includes:

[0021] like Figure 1 and Figure 2 The cooling-enhanced bottle bottom forming mold shown includes: a first sealing member 3, a base 1 and a mold core 2, and the mold core 2 is arranged on the base 1. In this embodiment, the base 1 and the mold core 2 adopt an integrated structure and can be processed with copper alloy, which has good thermal conductivity.

[0022] The bottom of the base 1 is concavely provided with a blind hole 4 extending upward into the mold core 2, and the first blocking member 3 is arranged in the blind hole 4. Figure 3 As shown, a first cavity 8 located above the first plugging member 3 and a second cavity 5 located below the first plugging member 3 are formed in the blind hole 4, which do not interfere with each other. In this embodiment, the first plugging member 3 adopts a tapered threaded plug, and a tapered threaded hole 6 corresponding to the tapered threaded plug is provided in the blind hole 4, which is convenient for assembly and has a stable structure.

[0023] A first cooling hole 7 extending obliquely upward to the first cavity 8 is provided at the bottom of the base 1, and a first air outlet 12 extending obliquely downward to the bottom of the base 1 is provided in the first cavity 8. Cold air can enter the first cavity 8 through the first cooling hole 7, penetrate into the mold core 2 to enhance the cooling effect, and be discharged through the first air outlet 12 to take away the heat of the base 1 and the mold core 2.

[0024] like Figure 2 As shown, the first air outlet holes 12 and the first cooling holes 7 are symmetrically distributed along the axis of the base 1 , and a combination of three groups of first air outlet holes 12 and first cooling holes 7 can be used to improve the heat dissipation effect and temperature distribution uniformity of the mold core 2 .

[0025] A second air outlet 13 connected to the first air outlet 12 is provided on the side of the base 1, and a second blocking member 14 is provided at the bottom of the first air outlet 12. In this embodiment, the second blocking member 14 is screwed, which is easy to assemble and seals the bottom of the first air outlet 12. The cold air in the first cavity 8 is delivered to the second air outlet 13 through the first air outlet 12, thereby extending the path of the cold air, which is beneficial to taking away more heat in the base 1 and the core 2.

[0026] like Figure 3 As shown, second cooling holes 11 extending into the second cavity 5 are arranged at intervals on the edge of the mold core 2, so that cold air can also enter the second cavity 5 through the second cooling holes 11 and be discharged through the bottom of the second cavity 5, thereby enhancing the heat dissipation of the base 1 and the mold core 2. The first cooling holes 7 and the second cooling holes 11 form a three-dimensional cooling air path, which can not only reduce the dead weight of the base 1 and the mold core 2, but also improve the heat dissipation and cooling effect.

[0027] like Figure 2As shown, a bottom forming cavity 9 is concavely disposed on the mold core 2 to form the bottom of the glass bottle. An exhaust hole 10 extending downward to the second cooling hole 11 is disposed in the bottom forming cavity 9, so that excess gas in the bottom forming cavity 9 can be introduced into the second cooling hole 11 for rapid exhaust, which is beneficial to the bottom forming of the glass bottle. In this embodiment, the diameter of the exhaust hole 10 is not greater than 1 mm, and the small diameter of the exhaust hole 10 prevents molten glass material from entering the exhaust hole 10.

[0028] In summary, the cooling-enhanced bottle bottom forming mold pointed out in the utility model reduces the dead weight of the mold, enhances the ventilation and heat dissipation effects of the base and the mold core, improves the structural stability during use, and is conducive to extending the service life of the mold.

[0029] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
