Abstract

"MéTODO E PRENSA PARA GRAMPEAMENTO DE MOLDE PARA MáQUINAS DE MOLDAGEM POR INJEçãO". Referente a uma prensa de fechamento de molde compreendendo uma placa de base estacionária (10) e uma placa de base móvel (12) conectadas operativamente a meios de controle (25, 25', 30) que podem ser operados para mover as placas (10, 12) em direção, e em afastamento, uma em relação à outra ; hastes-de-fecho deslizantes (16), cada uma delas conectada a um respectivo cilindro de controle (17), que se estendem axialmente entre as placas (10, 12) passando através de buchas de trava (1 8) suportadas, rotativamente, por uma das placas (10, 12) da prensa ; cada bucha de trava, e a correspondente haste-de-fecho (16), sendo providas com roscas de parafuso opostas (23, 24) que se encaixam tendo uma folga axial ; as buchas (18) sendo feitas para rotacionar em sincronismo e de um modo correlacionado com o deslocamento da placa de base móvel (12), evitando qualquer contato com atrito entre as roscas de parafuso (23, 24) durante o fechamento e abertura do molde ; as hastes-de-fecho (16) sendo então feitas para deslizar com relação às buchas de trava (18) e as placas de base (10, 12) da prensa, provocando um contato entre as roscas de parafuso (23, 24) das buchas e hastes-de-fecho (16), e uma tração das buchas (18) contra a placa de base móvel (12), da prensa, para gerar a tonelagem requerida para grampear o molde (11, 13) rigidamente.
