Abstract

Dispositivo para la fundición o inyección de neumáticos de vehículos, especialmente de neumáticos de vehículos automóviles, con un molde de varias partes, cuya oquedad, determinante de la configuración del neumático a fabricar, se limita a partir del interior, por un núcleo dividido y, a partir del exterior, por una parte superior y una parte inferior, cuyas partes son por lo menos parcialmente móviles en sentido axil y se establecen conjuntamente la zona del rodete y de la pared lateral del neumático, así como por una parte, subdividida en segmentos, que desmolde la zona de la superficie de rodadura del neumático, en lo que los segmentos están sujetos a soportes de segmentos que pueden moverse acercándose y alejándose respecto al núcleo, caracterizado porque los soportes de segmentos son corredizos tanto radialmente respecto al núcleo, así como también son oscilables acercándose, respectivamente alejándose, respecto al núcleo.
