Abstract
本实用新型提供一种大口径橡胶软管成型模具，属于橡橡胶软管制造技术领域，将胎芯设置为两端密封的中空管状结构，使压缩空气不必进入胎芯中，可直接作用于胎芯壁和橡胶软管之间，节省了压缩空气，节省能源及材料；胎芯的一端设置外螺纹，并固定连接有具有内螺纹的连接头，胎芯与连接头通过螺纹紧固连接，形成管胎，胶片硫化形成橡胶软管后，橡胶软管与管胎之间没有空隙，由于胎芯端部设置为外螺纹，连接头为内螺纹，除去连接头后，胎芯端部与橡胶软管之间出现空隙，预留空间，使得压缩空气更容易冲入胎芯与橡胶软管之间，使其相互脱离。
This utility model provides a large-diameter rubber hose forming mold, belonging to the field of rubber hose manufacturing technology. The tire core is designed as a hollow tubular structure sealed at both ends, allowing compressed air to act directly between the tire core wall and the rubber hose without needing to enter the tire core, thus saving compressed air, energy, and materials. One end of the tire core is provided with an external thread and is fixedly connected to a connector with an internal thread. The tire core and the connector are fastened together by the threads to form a tubular tire. After the rubber sheet is vulcanized to form the rubber hose, there is no gap between the rubber hose and the tubular tire. Because the end of the tire core is set with an external thread and the connector with an internal thread, a gap appears between the end of the tire core and the rubber hose after the connector is removed. This reserved space allows compressed air to more easily enter between the tire core and the rubber hose, causing them to separate.
