Abstract

<B>"MOLDE SEGMENTADO COM CENTRO FENDILHADO PARA CURA DE PNEUS"<D>. Um molde segmentado com centro fendilhado (10) para cura de um pneu completo compreende um topo de recipiente de molde (16) contendo uma chapa de parede lateral de molde superior (20) e uma pluralidade de segmentos superiores de banda de rodagem (18), dispostos equidistantes de um eixo central e encostamento adjacentemente entre si quando o molde é fechado; e um fundo de recipiente de molde (22) contendo uma chapa de parede lateral de molde inferior (26) e uma pluralidade de segmentos de banda de rodagem inferior (24) dispostos equidistantes do eixo e encostando adjacentemente entre si quando o molde é fechado. Cada um dos segmentos de banda de rodagem é elasticamente propendido em direção à linha central de molde (CL) por mecanismos de mola (38), e são deslizavelmente acoplados a superfícies troncónicas respectivas (76, 78) do recipiente de molde, de tal modo que o movimento vertical do topo do recipiente de molde ao longo do eixo de uma posição fechada até uma posição aberta é traduzido em movimento radial para fora dos segmentos superior e inferior de banda de rodagem no sentido oposto ao eixo. O plano correspondente (84) para os segmentos superior e inferior de banda de rodagem pode ser descentrado da linha central (CL) de molde. Cada chapa de parede lateral de molde corresponde aos segmentos de banda de rodagem em juntas de assentamento respectivas (72, 74) que limitam movimento radial para dentro dos segmentos de banda de rodagem. Conjuntos de pino (36) para cada segmento de banda de rodagem limitam movimento radial para fora dos segmentos de banda de rodagem.
