Abstract
"MáQUINA PARA MOLDAR A INJEçãO COM BUCHAS TRANSFERêNCIAS INTER-COLETORES", compreedendo uma máquina para moldar a injenção em multi-camadas, moldando dois materiais com diferentes temperaturas de injeção, tendo um espaço de ar de isolamento estendendo-se entre coletores de distribuição aquecidos frontal e traseiro. Bicos injetores aquecidos estendendo-se desde o coletor frontal, cada um tendo um canal central e um ou mais canais anulares estendendo-se ao seu redor. Buchas de transferência, cada uma tendo um furo longitudinal central que se estende através do espaço de ar, para conduzir o material derretido desde o coletor traseiro até um dos canais em cada bico injetor aquecido. Em outra configuração, cada bucha de transferência tem uma porção de cabeça que proporciona um espaçador entre os dois coletores e uma porção de tubo que estende-se através de um furo longitudinal, através do coletor frontal, até um dos bicos injetores aquecidos. Um espaço de ar ao redor da porção de tubo proporciona separação térmica entre o material derretido do coletor traseiro e do coletor frontal, o qual tem uma temperatura mais alta"MACHINE FOR MOLDING INJECTION WITH INTER-COLLECTING TRANSFER BUSHINGS", comprising a machine for molding multi-layered injection molding two materials with different injection temperatures, having an insulating air space extending between heated distribution manifolds front and rear. Heated injection nozzles extending from the frontal collector, each having a central channel and one or more annular channels extending around it. Transfer bushings, each having a central longitudinal hole that extends through the air space, to conduct the molten material from the rear manifold to one of the channels in each heated injection nozzle. In another configuration, each transfer bushing has a head portion that provides a spacer between the two collectors and a tube portion that extends through a longitudinal hole, through the frontal collector, to one of the heated injection nozzles. An air gap around the tube portion provides thermal separation between the melted material of the rear collector and the front collector, which has a higher temperature
