Abstract

La presente invención se refiere a mejoras en un molde de neumático ventilado, de un tipo que tiene un cuerpo de molde provisto con una cavidad receptora de neumático y con montajes para producir un patrón de piso preseleccionado, con un anillo de piso que tiene salientes o costillas laterales y transversales, provistas con ventilaciones de arco, cada costilla lateral tiene una ventilación de raco que dispone zonas de formación de bloque de piso individual, en comunicación abierta entre sí, cuyas mejoras se caracterizan porque la ventilación de arco tiene una forma de doble cuña y comprende pasajes en forma de cuña opuestos, conectados en sus vértices formados por superficies superior e inferior, inclinadas hacia abajo e inclinadas hacia arriba respectivamente, cada superficie inferior de cada pasaje en forma de cuña, se inclina hacia arriba de 30 a 50 grados, para formar, con las superficies superiores inclinadas hacia abajo, una garganta que tiene un área en sección transversal suficiente para ventilar aire atrapado entre la superficie superior de el piso del neumático y la superficie interior del anillo de piso, en un período de tiempo preseleccionado, suficiente para asentar la superficie exterior del piso contra la superficie interior del anillo de piso, cuya ventilación de arco está en una comunicación abierta con la línea divisoria horizontal del molde, que se ventea a la atmósfera.
