Abstract

"PRODUçãO DE ARTIGOS MOLDADOS E APARATO PARAPRODUZIR ARTIGOS MOLDADOS". é descrito um aparato demodelagem que compreende uma placa (12) que possui umacavidade de retenção (14) que recebe uma carga de materialmoldável. O material moldável na forma particulada ou fundida éalimentado em uma passagem aquecida através de um espiral dealimentação (40) em um tubo (36). Um êmbolo (42) desloca omaterial moldável fundido ao longo da passagem (30) e para dentroda cavidade de retenção (14). A placa (12) é, então, deslocadapara uma posição na qual a cavidade de retenção (14) é alinhadacom uma abertura (18) em uma placa (16). A abertura (18) está emcomunicação com uma cavidade (20) que possui o formato doartigo a ser produzido. Um segundo êmbolo (46) desloca a cargade material moldável fundido da cavidade de retenção (14) atravésda abertura (18) para a cavidade do molde.
