Description

Glass mould for one-step forming bottle

Technical Field

The utility model belongs to the technical field of the glass mold, concretely relates to glass mold for one shot forming bottle utensil.

Background

As is known in the art, a glass mold is divided into a blank mold and a molding mold, in which a glass melt in a molten state is introduced into the blank mold, a glass container preform (conventionally referred to as a "blank" in the art) is molded in the blank mold, and the blank is transferred to the molding mold by a robot of a line and row machine and blow molded. As can be seen from the foregoing description, two sets of molds, the above described blank mold and the molding mold, are required for each glass container to be molded. This form-molding, i.e., forming, has long been accepted by the bottling industry, and is especially accepted by convention as the requisite process. However, there are at least the following disadvantages objectively: firstly, two processes from the forming of an initial product to the forming of a finished product are required, so that the process is relatively long, and the forming efficiency is influenced; secondly, because two sets of moulds, namely a primary mould and a molding mould, need to be used, the using amount of the moulds is large, and the equipment cost for manufacturing the bottle is increased; thirdly, because of the staged forming, the energy consumption is large, and the method is not suitable for the energy-saving and economical spirit advocated by the whole society at present; fourthly, the efficiency of the line-row machine of the bottle-making manufacturer is obviously influenced; fifthly, for cosmetic bottles having four edges (the cross-sectional shape of the bottle body is rectangular) and a relatively thick bottom, it is difficult to form a bottle body having the ideal edge line portion profile and smooth and clean bottom surface.

Chinese patent CN209292200U recommends "a glass mold for one-step forming bottle making process", which can substantially eliminate the above-mentioned disadvantages of the applicant because it can form a glass container such as the cosmetic bottle mentioned above by using a set of molds, but the following disadvantages still exist: firstly, it can be seen from the structure shown in the figure of the patent that the choke plug is provided with an air passage which is communicated with the cavity, the function of the air passage is not mentioned in the specification, but the air passage is used for air-entrapping according to the common general knowledge, the so-called air-entrapping is to introduce compressed air into the mold, to force the glass frit to enter the cavity downwards and be embedded sufficiently, so as to make the bottle head, the air-entrapping is finished, and the air-entrapping head is used as the bottom of the primary mold to participate in the air-blowing work, however, for cosmetic bottles, the choke plug is not necessary to have the air-entrapping function, as long as the requirement of the bottom molding of the bottle body is met. Therefore, the arrangement of the air-breathing through hole on the choke plug can increase the complexity of the choke plug structure on one hand and increase the processing difficulty of the choke plug on the other hand; secondly, due to the structural design, when the punch is displaced upward during the forming process, the air generated in the mold cavity cannot be exhausted to the outside, so the bottle forming effect such as appearance and surface finish and the like are influenced to a certain extent. In view of the foregoing, there is a need for further improvement, and the technical solutions described below are made in this context.
