In the case of the emergence of a large variety of packaging materials, glass containers still occupy an important position in the packaging of beverages. Glass bottles are typically manufactured through four steps of compounding, melting, forming and annealing. In the forming process, the molten glass stock solution is required to be injected into a forming die with a water cooling system, and the forming die is rapidly cooled and formed, so that most of energy is stored in the glass bottle body to form internal stress, and if the internal stress is too large, the bottle body is easy to crack. In order to eliminate the internal stress, the glass bottle needs to be annealed to release the internal stress in the bottle body of the glass bottle.
Some technical solutions related to injection molds also appear in the prior art, for example, a chinese patent with application number 2018100971901 discloses a production process of a high-transparency glass bottle, which includes the following steps: (1) weighing the following raw materials: weighing 75-88 parts of quartz sand, 1.5-2.8 parts of lithium porcelain stone, 0.5-2.4 parts of mullite, 2.5-3.8 parts of dolomite, 0.5-3 parts of diopside, 2.8-5.5 parts of potassium feldspar, 1.5-3.5 parts of borax, 1.2-2.6 parts of calcined soda, 0.05-0.2 part of cerium oxide and 0.01-0.12 part of yttrium oxide; (2) mixing: ball milling; (3) high-temperature melting: feeding the mixed powder into a melting furnace, melting at 1450-1480 ℃, and keeping for 14-20h to obtain glass stock solution; (4) molding and processing: cooling to 1380-1400 ℃, and then blowing and forming; (5) annealing: transferring the glass bottle into an annealing furnace with the temperature of 535-555 ℃, preserving heat for 16-20min, then cooling to 350-375 ℃, preserving heat for 150min, and air-cooling to room temperature; the raw materials are reasonable in proportion, the melting temperature is lower than 1500 ℃, the process steps are matched with each other, the prepared glass bottle has high transparency, almost no internal stress exists in the glass bottle, the glass bottle has excellent strength, and the glass bottle can resist shock cooling and shock heating. But among the prior art accomplish the blowing in-process of glass bottle through the mould, need carry out rapid cooling to the mould for rapid solidification shaping after the bottle base inflation, nevertheless because the distribution inhomogeneity of cooling water course makes body cooling rate inhomogeneous, and the needs longer time that reduces the body just can make each position of body cool off to predetermined temperature, influences the production efficiency of glass bottle, and glass bottle intensity is lower simultaneously, and fragility is big, makes and meets local quench suddenly hot burst easily and splits and injure people after the shaping
