轮胎硫化模具的弹簧气孔套技术

介绍轮胎硫化模具的弹簧气孔套技术。弹簧气孔套由外壳、弹簧和阀杆组成，在弹簧的作用下，装胎硫化模具型腔中存留的气体从轴套与轴芯间间隙排出，通过阀杆移动，阻止胶料流入轴套内，避免硫化轮胎表面胶须产生。弹簧气孔套安装在硫化模具的排气孔内，安装孔经3次钻孔完成，钻孔的尺寸和公差由弹簧气孔套外径决定。安装弹簧气孔套的轮胎硫化模具清洗与常规方法相同，干冰清洗效果最佳。;The technology of spring blowhole sleeve for tire vulcanizing mould was introduced.The spring blowhole sleeve was composed of shell，spring and valve stem. Under the action of spring，the gas remaining in cavity of the vulcanizing mould with the tire was discharged from the gap between the sleeve and the core of the shaft，and the compound was prevented from flowing into the sleeve through the valve stem movement，thus avoiding the production of the rubber whiskers on the surface of vulcanized tires.The spring blowhole sleeve was installed in the exhausting hole of the vulcanizing mould.The installation hole was drilled three times，the size and tolerance of the drilling hole were determined by the outer diameter of the spring blowhole sleeve.The cleaning method of tire vulcanizing mould with spring blowhole sleeve was the same as that of the traditional tire vulcanizing mould，and the dry ice cleaning effect was the best
