Abstract

"PROCESSO PARA A PRODUçãO DE PEçAS DE FUNDIçãO, AREIA DE MOLDAR E SUA UTILIZAçãO PARA A EXECUçãO DO PROCESSO". A presente invenção coloca à disposição um processo com cuja ajuda podem ser fabricadas peças de fundição de alta qualidade, com configuração complexa, e onde depois do término do processo de fundição as partes do molde de fundição podem ser removidas da peça de fundição de modo simples e sem risco. Para tal, as seguintes etapas são realizadas: Fabricação de um material de moldagem, misturando-se um material de moldagem básico capaz de escorrer, inerte em relação à massa fundida de metal, que durante o aquecimento tem uma dilatação menor do que a areia quartzífera, e um agente aglutinante que durante o aquecimento tem uma dilatação diferente da do material de moldagem básico; produção de uma parte de molde de fundição do matedal de moldagem; composição de um molde de fundição com a utilização da parte de molde de fundição; verter a massa fundida de metal para dentro do molde de fundição para a obtenção de uma peça de fundição; esfriamento da peça de fundição durante um tempo de solidificação e de esfriamento, durante o qual a parte de molde de fundição é desintegrada em fragmentos; remoção dos fragmentos da parte de molde de fundição da peça de fundição; preparação dos fragmentos do material de moldagem para a obtenção de um material de moldagem básico capaz de escorrer."PROCESS FOR THE PRODUCTION OF FOUNDRY PARTS, MOLDING SAND AND ITS USE FOR THE IMPLEMENTATION OF THE PROCESS". The present invention provides a process with the help of which complex high quality casting parts can be manufactured and where upon completion of the casting process the casting mold parts can be simply removed from the casting and without risk. For this, the following steps are performed: Fabrication of a molding material by mixing a basic molding material capable of dripping, inert to the molten mass of metal, which during heating has a less swelling than quartz sand. and a binder which upon heating has a different expansion than that of the basic impression material; production of a casting part of the molding matte; composition of a casting mold using the casting mold part; pouring the molten mass of metal into the casting mold to obtain a casting piece; cooling of the casting part during a solidification and cooling time during which the casting mold part is disintegrated into fragments; removing fragments from the casting mold part of the casting part; preparation of fragments of impression material to obtain a basic impression material capable of dripping.
