Structure improved glass mould

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.
