Referring to fig. 1 to 4, a glass bottle molding die comprises a bottom die 1 and two half dies 2 clamping the bottom die 1, wherein the bottom die 1 and the half dies 2 jointly enclose a cavity 3, a vertical cooling hole 21 is vertically arranged on the half dies 2 in a penetrating manner, a heat preservation hole 22 is arranged at the bottom of the half dies 2, the heat preservation hole 22 is positioned between the vertical cooling hole 21 and the cavity 3, and the opening of the heat preservation hole 22 is blocked.

According to the utility model, the heat-insulating hole 22 is arranged between the vertical cooling hole 21 and the cavity 3 at the bottom of the glass bottle mold, the solid heat transfer path at the root of the mold is blocked, the heat-insulating hole 22 is blocked, the convection heat transfer of the gas in the heat-insulating hole 22 is reduced, the heat resistance of the external heat dissipation at the root of the glass bottle is increased, the too fast heat dissipation at the root of the mold is avoided, the unclear trademark and the cracks of the patterns caused by the too fast cooling of the bottle bottom are avoided, and the product percent of pass is improved. The heat-insulating holes 22 can be sealed by screws 221 or copper particles 222, or a part of the heat-insulating holes 22 can be sealed by screws 221 and a part of the heat-insulating holes 22 can be sealed by copper particles 222. Preferably, as shown in fig. 3 and 4, the bottom mold 1 is partially sunk into the heat-insulating holes 22, and convection of gas in the heat-insulating holes 22 can be further reduced.

The utility model aims to give consideration to high-efficiency continuous production and high-quality continuous production as far as possible, and the method is sequenced according to the heat dissipation speed, wherein the vertical cooling holes 21 are arranged, and the vertical cooling holes 21 and the heat preservation holes 22 are arranged, so that the vertical cooling holes 21 are not arranged. Specifically, the horizontal distance between the heat preservation hole 22 and the cavity 3 is 12-15mm, the heat preservation hole 22 is close to the cavity enough, and meanwhile, the half mold 2 is guaranteed to have enough strength to maintain the pressure of the molten glass.

Three ways of heat transfer are convective heat transfer, thermal radiation and molecular vibrational heat transfer. Since the density of the solid substance is generally larger, the molecular vibration heat conduction capacity of the solid substance is generally larger than that of liquid and gaseous substances with the same components, generally speaking, the gas heat resistance is larger than that of metal, after the heat preservation hole 22 is arranged, the path of the heat dissipation of the molding die 2 radially outwards is partially blocked, and only the solid part between the heat preservation hole 22 and the heat preservation hole 22 can transfer heat through molecular vibration. Convection heat transfer is the main mode for realizing heat exchange between liquid and gas, and after the heat preservation hole 22 is plugged, the convection strength of the gas in the heat preservation hole 22 is weakened, and the thermal resistance is further increased. After the vertical cold air is blown in from bottom to top, the bottom of the molding die 2 is cooled slowly due to the fact that the bottom of the molding die is cooled slowly, the cooling air is heated slowly, and the whole glass bottle is cooled more uniformly.

Referring to fig. 4, the insulation hole 22 may be a vertical through hole, and both the upper and lower openings are sealed. Preferably, as shown in fig. 3, the heat-insulating hole 22 is a vertical blind hole, the lower end opening is blocked, and only the bottom of the glass bottle needs to be insulated. Furthermore, the depth of the heat-preserving hole 22 accounts for 20% -27% of the height of the half mold 2, usually 60mm, as shown in fig. 3, and is extended to the position of the half mold 2 for molding the lower part of the glass bottle body, so as to avoid the over-fast cooling near the bottle bottom and reduce the heating speed of the vertical cooling wind.

From the bottom view, the vertical cooling holes 21 and the heat preservation holes 22 are distributed around the circumference of the cavity 3, and the vertical cooling holes 21 are arranged on the periphery of the heat preservation holes 22. In some embodiments, the cooling holes 21 surround the cavity 3 twice, the insulation holes 22 surround the cavity 3 once, and the insulation holes 22 are preferably sealed by screws 221 for easy assembly and disassembly, but in order to ensure that there are enough dense insulation holes 22 to increase thermal resistance, the distance between adjacent insulation holes 22 is only 2-3mm, if all the insulation holes are sealed by screws 221, the half mold 2 is easily damaged, and therefore the insulation holes 22 need to be used at intervals, specifically, one insulation hole 22 is sealed by a screw 221 every 6-8 insulation holes 22 sealed by copper particles 222.
