Abstract
A glass forming furnace includes a forming zone, a cleaning zone, a plurality of sealing doors, and a conveying channel. The forming zone includes a pressure device. The pressure device includes a servo motor, a push rod, and a mold pressurizing mechanism. The push rod is connected with the servo motor. The push rod includes an end notch and an embedded structure. The mold pressurizing mechanism includes an inlet notch. The inlet notch is connected with the embedded structure. Wherein, the end notch is in contact with the inlet notch. The cleaning zone includes an active brush mechanism. The sealing doors are disposed at an inlet and an outlet of the forming zone, respectively. The sealing doors each include a valve. The valve has a cross-sectional thickness that is gradually decreased from top to bottom. The conveying channel passes through the forming zone and the cleaning zone. The conveying channel is configured to convey a plurality of glass forming molds. The beneficial effect of the present invention is that the heating zone can be sealed and the molds can be cleaned more effectively.
