Abstract

MéTODO DE VAZAMENTO, DISPOSITIVO E PRODUTO FUNDIDO EM UM PROCESSO DE MOLDAGEM A VáCUO. Um método de vazamento e um dispositivo em um processo selado a vácuo para a produção de um fundido de parede fina pelo uso de uma armação de molde para o processo selado a vácuo, e um produto bruto fundido usando o método de vazamento são providos. O método de vazamento compreende as etapas de: cobertura de forma selante da superfície de uma placa de modelo por um membro de blindagem; posicionamento de uma armação de molde no membro de blindagem e, então, a colocação de um enchimento que não inclui qualquer aglutinante na armação de molde; cobertura de forma selante da superfície superior do enchimento e, então, a colocação sob vácuo do interior da armação de molde para a sucção do membro de blindagem para enchimento do espaço do membro de blindagem; remoção da placa de modelo do membro de blindagem, desse modo se formando uma metade de molde que tem uma superfície de moldagem; formação de uma outra metade de molde de uma forma similar, e a combinação das metades de molde para a definição de uma cavidade de moldagem; vazamento do metal fundido na cavidade de moldagem; e liberação da pressão negativa na rmação de molde para a remoção como um produto bruto fundido, e ainda compreende a etapa de descompressão da cavidade de moldagem, antes do z do metal fundido no molde combinado. Desenho Selecionado: Figura 1.
