All-steel giant engineering radial tire mouth-shaped plate

The utility model relates to an all-steel giant engineering radial tire mouth-shaped plate, the main body of which is a mouth-shaped plate, the mouth-shaped plate is provided with a front-back through rubber runner, the rubber runner is divided into a front runner section and a rear runner section from back to front, the aperture of the rear runner section is gradually reduced from back to front, and the aperture of the rear runner section is gradually reduced from back to front. The structure is characterized in that the included angle between the left side and the bottom side of the front runner section is 75 degrees, and the included angle between the right side and the upper side is 60 degrees. Compared with the prior art, the large all-steel radial tire mouth-shaped plate has the beneficial effects that part of parameters of the large all-steel radial tire mouth-shaped plate are redesigned, so that the produced tire body and belted layer semi-finished product surface sizing material coated steel wires ar
