Abstract

La presente invención se refiere a un molde de banda de rodadura para moldeo por inyección de una banda de rodadura sobre una superficie radialmente externa de un cuerpo anular flexible, inflado, colocado en el molde, con la superficie radialmente externa separada de una superficie de moldeo de banda de rodadura del molde para formar una cavidad de banda de rodadura de llanta, una pluralidad de compuertas circunferencialmente espaciadas en el molde, en comunicación con la cavidad de banda de rodadura de llanta que proporcionan porciones de compuerta alrededor de la cavidad, elementos para inyectar un material de moldeo fluído, viscoelástico hacia las porciones de compuerta de la cavidad de banda de rodadura, a través de las compuertas y hacia porciones remotas de la cavidad de banda de rodadura de llanta espaciada axialmente del cuerpo anular flexible a partir de las compuertas, caracterizado por elementos para regular el flujo del material de moldeo fluído a las porciones de compuerta y las porciones remotas de la cavidad de banda de rodadura de llanta, elementos para inflar el cuerpo anular flexible a una presión relativamente baja durante la inyección del material de moldeo fluído, para permitir la distribución de cantidades predeterminadas del material de moldeo fluído alrededor de la cavidad y elementos para aumentar la presión en el cuerpo anular flexible a una presión elevada durante el curado del material de moldeo fluído sobre la superficie radialmente externa del cuerpo anular flexible en la cavidad de banda de rodadura de llanta.
