Abstract

SISTIDOS POR FLUIDO". Aparelhos e processos para sdo ou sistemas de moldagem por co-injeção. Um par ionados em uma tubeira de entrada de molde (12) e ir a passagem de material plástico líquido e de um fluido para o interior da cavidade de molde. Um membro de pino interno (54) é posicionado no interior de um membro de pino oco (52) e ambos os membros de pino (52, 54) são controlados por membros de êmbolo (60, 62) que são seletivamente deslocados em um membro de bloco (16) por pressurização seletiva de uma fonte hidráulica ou pneumática. Os deslonte controla a operação dos membros de pino (52, 54) e assim a operação do sistema de moldagem por injeção assistido por fluido.
