Structure improved glass mould

Abstract

The invention relates to a structure improved glass mould. The glass mould includes a pair of bottle half-dies, each bottle half-die has a bottle half-die cavity and a bottle bottom die cooperating cavity under the bottle half-die cavity, first axial exhaust holes are arranged in the semi-arc direction of the bottle half-die, and extend downward from the top of the bottle half-die to an air outletring groove, which is arranged on the outer wall of the bottle half-die, second axial exhaust holes are arranged in the semi-arc direction of the bottle half-die and on the inner sides of the first axial exhaust holes, the second axial exhaust holes correspond to the neck and shoulder area of the bottle half-die, and the bottle half-die cavity and the second axial exhaust holes are communicated by radial exhaust holes. The glass mould is characterized in that: an edge accelerated cooling mechanism is formed around the semi-arc direction of the bottle half-die corresponding to a position abovethe air outlet ring groove on the outer wall of the bottle half-die, switches off the lower ends of the first axial exhaust holes, and enables communication of the lower ends of the first axial exhaust holes with itself. The structure improved glass mould can improve the manufacturing efficiency of glass containers with rectangular cross-sections and guarantee the quality of glass containers.

Description

technical field [0001] The invention belongs to the technical field of glass molds, in particular to a glass mold with improved structure. Background technique [0002] Since the glass mold can be divided into the initial mold and the molding, the glass mold mentioned above refers to the molding of the glass mold. There is no lack of technical information about glass molds in the published Chinese patent documents, such as CN101298355A (mold for making glass containers), CN101298356A (mold for making glass containers), CN101298357A (mold for processing glass containers), CN101298358A (a mold for making glass containers) glass container processing), CN101298359A (mold for glass container processing), CN101941791B (mold for making bottle glass containers), CN102515471B (mold for making bottle glass containers) and CN102320718A (for making molds for glass containers), etc. In foreign patent documents, technical information related to glass moulds, such as US2006 / 0212632A, can...

Problems solved by technology

However, due to the fact that the wall thickness of the four corners (also known as "edges") of some bottles such as pickle bottles, braised product bottles, etc., which are rectangular (usually square) in cross section, is significantly thicker than that of other parts. Such as the four walls, so in the process of manufacturing such bottles, the cooling rate of the glass melt at the four corners, that is, the four edges, will be significantly slower than other parts

In particular, due to the significant difference in the cooling rate between the edge and the wall, it will affect the efficiency of bottle making on the one hand, and the quality of the bottle on the other hand. Specifically, because the industry still lacks effective and positive countermeasures However, the quality of bottle making can only be guaranteed by sacrificing the negative way of reducing the speed of bottle making. However, this negative way not only increases the cost of bottle making, but also is not conducive to saving energy
