The three patent schemes are all proposed around the heat dissipation of the mould.

The above-mentioned patented technical solutions are all proposed for bottles with bottlenecks such as beer bottles and red wine bottles. It should be said that each has unique technical advantages, but there are disadvantages, because after the glass products are formed in the glass mold, the formed glass products need to be clamped with bottle tongs. The glass bottle is taken out of the mold. The higher the quality of the wine bottle, the higher the quality requirements, which is specifically reflected in the strict requirements on the consistency of the shape of the neck and shoulder. As we all know, the thickness of the bottle mold used to form wine bottles near the neck and shoulders is thick, and the heat is difficult to dissipate quickly. Therefore, when the bottle is taken out with bottle tongs, the glass frit at the neck and shoulders of the bottle is not heated due to high temperature. Reach the degree of hardening like the bottle body, that is to say, the neck and shoulders of the bottle still have a certain degree of plasticity, so when the bottle tongs hold it, it is easy to cause the neck and shoulders of the bottle to elongate and deform due to the gravity of the bottle itself, affecting The quality of the bottle. However, in the above-mentioned many patent application schemes, no technical inspiration for solving the deformation of the neck and shoulders of the bottle has been given. For this reason, the applicant has made active and beneficial explorations and found a solution to the problem. The technical scheme to be introduced below It was against this background that it emerged.
