Abstract

VEDAçãO DE VIROLA DE VáLVULA DE RETENçãO PARA UMA MáQUINA DE MOLDAGEM à INJEçãO. Uma válvula de retenção para uma máquina de moldagem. A válvula de retenção tem uma parte de haste e uma parte de anel movível ao longo da dita parte de haste entre uma posição aberta do canal de material fundido e uma posição fechada do canal de material fundido. Um sulco é formado em uma face dianteira da parte de anel. O sulco, em operação, recebe material fundido para forçar uma parte circunferencial externa do anel em uma direção radial para fornecer uma vedação entre a parte de anel e uma parede na máquina.
