The utility model relates to the field of glass bottle manufacture, and discloses a glass bottle mould comprising a finish mold, an original mold and a choke plug component, wherein a glass bottle-shaped cavity is arranged in the original mold; the finish mold is embedded in the original mold and is connected with the cavity; the choke plug component is arranged at the top of the original mold, and comprises a base and a mold insert; the mold insert is embedded in the bottom of the base and can slide freely in the vertical direction. During the formation stage of a primary blank, frit to be formed is pre-placed in the cavity; and when air is led in from the finish mold to blow the frit in the original mold slowly, the fluid frit can flow to edges from the middle due to the extruding force of air during the primary formation stage and the downward extruding force generated due to the dead weight of the mold insert, so that frit in the middle and frit on the edges are the same in thickness.
