Abstract

"PROCESSO PARA MOLDAR ESCOVAS DE DENTES UTILIZANDO UM MOLDE COM PEçAS DE MOLDE RELATIVAMENTE MóVEIS, E, APARELHO DE MOLDAGEM PARA REALIZAR O MESMO" No processo proposto para moldagem de escovas de dentes é utilizado um molde com peças de moldagem relativamente móveis (14, 16) que definem no mínimo uma cavidade de moldagem (20), que corresponde em forma a um corpo de escova de dentes. Uma das peças de moldagem (16) tem uma cavidade que define uma porção cabeça de escova, com uma pluralidade de furos (24), para penetração parcial para o interior da porção cavidade de um número similar de tufos de fibra. Material de moldagem plastificado é injetado sob pressão para o interior da cavidade (20). A pressão dentro da cavidade é sensoriada durante a etapa de injeção. A injeção é interrompida quando a pressão dentro da cavidade excede um valor de pressão predeterminado, evitando com isto qualquer vazamento de material de moldagem através dos furos (24).
