Automatic safe blow molding device for glass

Abstract

The invention provides an automatic safe blow molding device for glass, and relates to the technical field of blow molding of glass. The automatic safe blow molding device for the glass comprises a blowing mold, a glass bottle is inserted into the blowing mold, a blow molding mechanism is inserted into the glass bottle and comprises a blowing rod, a clamping block is slidably connected into an inner wheel, a crank rod is hinged to the outer side of a swing plate, and a friction block is hinged to the side, away from the swing plate, of the crank rod. According to the automatic safe blow molding device for the glass, when the air pressure in a pressure stabilizing cavity is large, a pressure relief pipe is opened through the air pressure, and the air pressure in the pressure stabilizing cavity returns to normal through the pressure relief pipe, when the air pressure in the pressure stabilizing cavity is small, the electromagnet drives an air pressure plate to ascend, the air pressure plate drives an air valve to slide through a transmission rope, the air valve opens the pressurizing pipe, and through cooperative use of the pressurizing pipe and a standby gas cylinder, the effects that the blow molding pressure can be automatically stabilized, and the blow molding quality is high are achieved.

Description

technical field [0001] The invention relates to the technical field of glass blow molding, in particular to an automatic safety blow molding device for glass. Background technique [0002] Glass is a non-crystalline, amorphous solid, of which glass bottles are the most common. Glass bottles need to be blown during processing. During the blow molding process of existing glass bottles, due to the wind coming out of the blowing tube It has been acting on the bottom of the glass bottle, and the blowing pressure is not uniform enough, which will cause the thickness of the bottom of the glass bottle to be different after forming. At the same time, the existing automatic blow molding device will have unstable air pressure during the blow molding process. The function of automatic voltage stabilization leads to different levels of quality of glass bottles. [0003] Aiming at the deficiencies of the prior art, the present invention provides an automatic safety blow molding device fo...

[0003] Aiming at the deficiencies of the prior art, the present invention provides an automatic safety blow molding device for glass, which has the advantages of ensuring uniform blow molding pressure, consistent blow molding thickness, automatically stabilizing blow molding pressure, and high blow molding quality. In the process of blow molding some glass bottles, because the wind has been acting on the bottom of the glass bottle after it comes out of the blow molding tube, the blow molding air pressure is not uniform enough, which will cause the thickness of the bottom of the glass bottle to be different after forming, and at the same time Some automatic blow molding devices may have unstable air pressure during the blow molding process, and do not have the function of automatic pressure stabilization, resulting in different levels of glass bottle quality
