Abstract

"BOCAL PARA A INJEçãO DE SUBSTâNCIA PLáSTICA FUNDIDA EM UM MOLDE". Bocal para a injeção de plástico fundido, compreendendo uma porção central traseira (1) terminando com uma superfície plana (6) em sua zona central, um elemento anular externo (5) terminando com uma correspondente superfície plana (7) em seu lado traseiro, sendo que a superfície plana terminal (6) da dita zona central é situada em uma posição mais recuada com respeito à superfície plana terminal (7) do dito elemento anular, o qual é provido por trás com uma primeira fenda anular (12) na forma de um ângulo agudo entre a aresta externa da porção traseira e a aresta externa do elemento anular. O último é também provido, na frente, com uma fenda anular (8), disposta em um ângulo agudo dentro da aresta frontal externa da dita porção traseira. As ditas duas fendas anulares (12, 8) são opostas uma à outra e se expandindo afastando-se uma da outra, e os ângulos respectivos vão substancialmente até o lado de cada outra, na mesma altura do bocal.
