Abstract

"PORTA PARA MOLDAGEM POR INJEçãO DE COMPOSTOS DE BORRACHA" é descrita uma combinação de sistema de porta de injeção de borracha (24) e método de moldagem por injeção de borracha, para produzir modelos de escoamento desejados na borracha. A porta de combinação (24) direciona a borracha por uma primeira região (26), para escoar em ângulos transversais (38, 40) pela porta de injeção (24), relativos à direção de escoamento da borracha (22), pela porta de injeção (24). A borracha (22) é depois direcionada por uma região adjacente (28) para escoar pela porta de injeção (24) em uma direção paralela à direção de escoamento da borracha (22), por toda a porta de injeção (24). A porta de combinação (24) produz um fluxo altamente misturado e uniforme de borracha (2), que é particularmente útil quando da moldagem por injeção da borracha com carga de fibra, em que se deseja orientar as fibras em uma direção particular.
