Abstract

para fornecer um método de moldagem pelo qual a densidade de areia de um molde é quase uniforme. o método compreende uma passo de formação de um espaço de moldagem usando um frasco, usando um frasco auxiliar que tem uma abertura inferior que é conectável a uma abertura superior do frasco, usando uma cabeça de aperto que tem uma placa de aperto e tem uma pluralidade de pés de aperto que passam através da placa de aperto e movem verticalmente, e usando uma placa de padrão, um passo de preencher a areia de moldagem para o espaço de moldagem, e um passo de apertar a areia de moldagem por baixar a cabeça de aperto, em que os pés de aperto que enfrentam uma concavidade de um padrão são baixados ao mesmo tempo que o passo de aperto começa ou durante o passo de aperto.to provide a molding method whereby the sand density of a mold is almost uniform. The method comprises a step of forming a molding space using a vial, using an auxiliary vial having a lower opening that is connectable to an upper vial opening, using a clamping head that has a clamping plate and has a plurality. of clamping feet passing through the clamping plate and moving vertically, and using a pattern plate, a step of filling the molding sand into the molding space, and a step of tightening the molding sand by lowering the molding head. clamping, wherein the clamping feet facing a concavity of a pattern are lowered at the same time as the clamping step begins or during the clamping step.
