Abstract

METODO PARA DESMOLDAR MATERIAL POLIMÉRICO A PARTIR DE UM MOLDE, E, MOLDE DE PNEUMÁTICO COM UMA FERRAMENTA DE DESMOLDAGEM. São revelados métodos e aparelho para desmoldar um material polimérico de um molde, os métodos compreendendo as etapas de colocar um material em um molde, fechar o molde, moldar o material localizado no molde, e abrir o molde. O molde inclui uma ferramenta de desmoldagem com uma porção de encaixe de material que fica em comunicação fluida com a porção do molde, a ferramenta de desmoldagem sendo reversivelmente desencaixável do primeiro elemento do molde. A ferramenta de desmoldagem é desencaixável de uma posição de repouso dentro do primeiro elemento do molde para transladar do primeiro elemento do molde o material polimérico moldado associado com a porção de encaixe de material, separando assim uma porção do material polimérico moldado da cavidade do molde. Em modalidades particulares, a porção de encaixe de material é uma cavidade. Em outras modalidades, a porção de encaixe de material é associada com um ou mais elementos longitudinais que estendem-se através de uma porção do primeiro elemento do molde.
