Abstract

"UNIDADE DE INJEçãO PARA O PROCESSAMENTO DE MATERIAIS FUNDìVEIS". A presente invenção refere-se a uma unidade de injeção para o processamento de materiais fundíveis, por exemplo termoplásticos, composições cerâmicas ou metálicas ou similar, em que pelo menos dois fluxos de material fundido são alimentados por meio de um sistema de canal para uma ou mais cavidades de molde em uma seqüência que muda com o tempo. De acordo com a invenção, somente um elemento de válvula rotativa é fornecido para cada sistema de canais que leva à cavidade (cavidades) de molde e consiste em pelo menos dois canais de alimentação (6;7). O elemento de válvula consiste em uma haste oca (11), que é conectada ao canal de pressão (20) do material fundido e tem, no plano dos canais de alimentação (6;7) levando à cavidade (cavidades) de molde, pelo menos um canal de distribuição (21) que se desloca radialmente para fora e é igualmente conectado ao canal de pressão (20).
