Abstract

"MECANISMO DE MOLDAGEM POR INJEçãO COM NúCLEO REFRIGERADO", compreendendo um mecânismo de rotor aquecido de moldagem por injeção possuindo um núcleo de molde refrigerado com uma porção alongada do corpo, com uma porção frontal ou cabeceira. Um tubo de resfriamento estendendo-se centralmente na porção do corpo do núcleo do molde. Um circuito de fluido de resfriamento que se estende a partir de uma extremidade frontal aberta, do tubo de resfriamento, externamente através de um número de perfurações radiais espaçadas. Cada perfuração se conecta a um ducto no formato em L, direcionando de volta a um espaço cilíndrico ao redor do tubo de resfriamento."INJECTION MOLDING MECHANISM WITH COOLED NUCLEUS", comprising a heated injection molding rotor mechanism having a cooled mold core with an elongated body portion, with a front or head portion. A cooling tube extending centrally in the body portion of the mold core. A cooling fluid circuit that extends from an open front end of the cooling tube, externally through a number of spaced radial perforations. Each perforation connects to an L-shaped duct, directing it back to a cylindrical space around the cooling tube.
