Abstract

"PROCESSO E DISPOSITIVO DE SOBREMOLDAGEM DE UM RECIPIENTE CAVADO". A presente invenção refere-se a um processo de sobremoldagem de um recipiente cavado (7) dotado de um gargalo (70) e de um corpo axial (71) que compreende tipicamente um rebordo (72), uma parede lateral (73) e um fundo (74), esse recipiente cavado (7) de altura axial H e de maior seção transversal S sendo, por exemplo, um frasco em vidro: a) coloca-se em um molde (2) aberto esse recipiente cavado (7), depois, após ter fechado esse molde, b) injeta-se nessa cavidade axial (21) formada um fluxo de matéria termoplástica fundida (6), de maneira a formar uma camada externa (80) dessa matéria plástica e assim obter um recipiente dito 'sobremoldado' (8); c) depois, abre-se esse molde (2) e ejeta-se desse molde (2) esse recipiente sobremoldado (8). Esse processo é caracterizado pelo fato de: 1. esse molde (2) estando aberto, esse gargalo (70) vai contra uma peça de apoio axial (4), de maneira a ocultar esse gargalo (70) durante essa sobremoldagem; 2. essa parede lateral (73) desse recipiente (7) ser colocada, tipicamente antes do fechamento desse molde, em um meio de posicionamento lateral (3) apto a ser deslocado axialmente, segundo uma direção axial (22) do molde (2); 3. após fechamento desse molde (2), se deslocar axialmente esse meio de posicionamento lateral (3) à medida que esse fluxo de matéria (6) injetado nessa cavidade axial (21) e formando um fluxo anular (6<39>), avança axialmente nesse molde, envolvendo essa parede lateral (73). Vantagens: sobremoldagem reproduzível e de forma predeterminada. Moldagem à elevada cadência e de elevada produtividade.
