Abstract

''COMPONENTE DE PLáSTICO OCO MOLDADO POR INJEçãO A GáS E PROCESSO E DISPOSITIVO PARA SUA PRODUçãO''. Artigo de plástico oco moldado por injeção a gás, por exemplo, uma grelha de radiador para um veículo a motor, compreendendo um suporte retangular (2, 3, 4) com elementos de suporte oco superior e inferior (2, 3) e moldagens ocas intermediárias (6, 7, 8), todas as quais são moldadas por injeção de gás em uma peça única uma com a outra. Os elementos de suporte (2, 3) e as moldagens (6, 7, 8) têm partes de extremidade unidas nos elementos de suporte lateral (4), e têm cavidades com área de corte transversal diminuindo na direção das extremidades.'' HOLE PLASTIC COMPONENT MOLDED BY GAS INJECTION AND PROCESS AND DEVICE FOR ITS PRODUCTION ''. Hollow plastic article molded by gas injection, for example, a radiator grille for a motor vehicle, comprising a rectangular support (2, 3, 4) with upper and lower hollow support elements (2, 3) and hollow moldings intermediate (6, 7, 8), all of which are molded by gas injection in one piece with each other. The support elements (2, 3) and the moldings (6, 7, 8) have end parts joined to the side support elements (4), and have cavities with a cross-sectional area decreasing towards the ends.
