technical field

The utility model belongs to the technical field of glass moulds, in particular to a mold for making glass containers .

Background technique

Glass containers such as glasses, cosmetic bottles, all kinds of pickle bottles, vases, wine bottles, beverage bottles, etc., the production of such glass bottle containers needs to rely on corresponding bottle molds. Regarding the bottle molds used for manufacturing glass containers, there are many examples in the patent literature. Among them, the glass molds surrounding the production of beer bottles and wine bottles are in the majority, and the mold used for making glass containers is typically recommended by the publication number CN101298355A. This patented technical solution is in The upper part of a pair of bottle half-molds and corresponding to the surrounding of the bottle neck cavity are provided with insulation holes to increase the temperature around the bottle neck cavity so that the liquid material, that is, the glass melt, can be evenly distributed when blowing twice during the molding process, ensuring the bottle neck. The wall thickness is the same; Publication No. CN101298356A provides a mold for making glass containers. This solution has the same effect as the aforementioned CN101298355A. For details, please refer to the 12th line on page 1 to the 10th line on page 2 of the specification for this patent application CN101298357A discloses a kind of mold that processing glass container is used, and this patent application scheme is in the height direction of a pair of mold halves and around the surrounding interval of half molds to offer upper and lower ventilating holes, reduce the temperature of bottle by ventilating hole, Avoid the deformation of the bottle due to high temperature; CN101298358A discloses a mold for glass container processing, which is to open cooling holes on the outer walls of a pair of bottle half molds, so that the heat dissipation is accelerated, the temperature of the mold cavity is quickly reduced, and the molding speed of the bottle is increased. Improve the production capacity per unit time; CN101298360A discloses a mold for processing glass containers, the program is to provide a vacuum hole on both sides of the height direction of the bottle mold cavity, and on the side of the bottom mold core of the bottom mold There are ventilation holes that are equal in number to the vacuum holes and connected to each other, and a center hole is opened in the center of the bottom mold core to connect with the vacuum device pipeline and communicate with the ventilation holes. This scheme can improve the quality of a pair of half bottles. The clamping effect of the mold can control the deformation of the pair of half molds, so that the processed glass container is smooth and ribless to ensure the quality.

In addition to the above-mentioned Chinese patent applications, JP 2004-31237A discloses a small-caliber glass bottle forming mold design-column machine blowing-bottle making method, W02006/098984A2 reports a glass forming mold, and US2006/0213632A1 recommends a glass forming mold. 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.

In order to avoid the deformation of the neck and shoulders in the process of forming a pair of bottles, the following two structural forms are generally adopted in the prior art; one is to set heat transfer holes on the half-mould of the bottle and around the side of the bottle neck cavity at intervals, and A heat transfer column with good heat transfer effect is placed in each heat transfer hole, such as a copper column. For details, please refer to the "mold for making a glass container" recommended by the utility model patent CN201746442U; On and around the side of the bottle neck cavity, a plurality of rows (that is, multiple rows) are provided at intervals, and each row (that is, each row) has a plurality of vent holes, and all the vent holes are communicated with the longitudinal vent holes provided on the bottle half mold.

The former in the above two structural forms has the following shortcomings: one is troublesome to manufacture, because in addition to opening the heat transfer column hole, the heat transfer column needs to be inserted; Rapid prototyping, because the heat transfer by the heat transfer column not only has a self-heating process, but also the speed of heat transfer is much slower than that of heat convection; the third is not conducive to saving expensive copper resources. And the latter in the above-mentioned two ways has the following disadvantages: the one, processing is troublesome, because the operation process of setting up many rows around the bottle neck cavity and usually having 3-4 air holes in each row is tedious; the other is that the air holes are easy to appear clogging, and once clogged it is often difficult or impossible to remove.

In view of the above prior art, it is necessary to improve it, for which the applicant has made a beneficial design, and the technical solution to be introduced below is based on this premise .
