Background

The mold is an important device in the production of glass bottles, and the quality and the yield of the glass bottles are closely related to the quality of the mold. In the production process of the glass bottle, firstly, a primary mold is needed to be used for carrying out primary forming on high-temperature glass materials, then, the glass materials are transferred to a forming mold for carrying out final air blowing cooling forming, and the air blowing forming step is mainly used for enabling the outer surface of the glass bottle to be more attached to the inner cavity of the mold, so that the appearance of the bottle shape is smoother.

When the glass material is blown and formed in the forming mold, the bottle opening mold, the bottle body mold and the bottle bottom mold are required to be matched and formed. The existing bottle body mold is generally provided with a heat dissipation channel 01 which is parallel to the central axis of a mold cavity and extends axially on a mold body, and is used for introducing liquid or cold air to carry out liquid cooling or air cooling heat dissipation. However, for narrow-neck bottles (i.e. bottle shapes with gradually narrowing shoulder and neck and increasing wall thickness), the shoulder and neck are far from the heat dissipation channel 01, which makes heat dissipation difficult, as shown in fig. 1. Therefore, uneven heat dissipation can occur at the bottle shoulder, the bottle opening and the bottle body, which easily causes deformation of the finished bottle.

In addition, residual gas between the preliminarily molded glass bottle and the mold cavity needs to be exhausted during the blow molding process, and in the prior art, an exhaust passage (not shown) is generally vertically arranged on the side wall of the mold to communicate with the mold cavity, and the residual gas is exhausted from the exhaust passage. However, if the exhaust passage is too large, obvious round hole traces are easy to appear on the bottle body, and if the exhaust passage is too small, residual gas cannot be rapidly and timely exhausted, which easily causes defects of finished products.

Accordingly, the prior art is in need of improvement and development.
