Abstract

The invention relates to a blowing head for forming glass products, the blowing head for forming glass products comprises a nozzle body and a blowing tube, the nozzle body is internally provided with an air inlet channel, the blowing tube is installed in an air inlet channel, the head end of the blowing tube is provided with a blowing head, the blowing closes a space between the blowing tube and the air inlet channel, the nozzle body is uniformly provided with a plurality of vertical balanced airways outside the air inlet channel, the lower part of the nozzle body is provided with a cavity, the cavity is internally provided with a ventilation groove, the ventilation groove and the vertical balanced airways are communicated, a current sharing ring is arranged inside the cavity, a plurality of balanced air holes are evenly arranged on the ring body of the current sharing ring, the balanced air holes and the cavity are communicated, the nozzle body is provided with a transverse air exhausting hole, an inlet of the transverse air exhausting hole is communicated with the air inlet channel, an outlet of the transverse air exhausting hole is provided with an air exhausting device, and the air exhausting device controls the air exhausting amount of the air exhausting hole; and in a glass product forming process, through controlling of the air exhausting amount of the air exhausting hole, internal and external air pressures of a bottle mouth can be controlled, the pressure at the bottle mouth can effectively be balanced, bottle mouth cracks and other problems can be prevented, and the quality of the glass products can be improved.

Description

technical field [0001] The invention relates to a mold for producing glass products, in particular to a glass product forming air blowing head for producing glass mold products. Background technique [0002] The blowing head for glass product molding is a common part in the production process of glass products. For example, the blowing head of a bottle making machine disclosed in the patent document of application publication number CN102583960A, the blowing head includes the blowing head body. There is an air intake pipe vertically at the center of the head body, and an air blowing pipe is arranged in the air intake pipe. The root of the air blowing pipe is closely matched with the entrance of the air intake pipe. In the gap, an exhaust pipe is arranged obliquely in the blowing head body, one end of the exhaust pipe is connected to the middle part of the air intake pipe, and the other end of the exhaust pipe leads to the outside of the blowing head body. The blowing head a...
