Abstract

dispositivo para o suporte de núcleos em componentes metálicos, que são empregados na construção de máquinas especialmente em motores, bombas, compressores ou instalações de usina de força, e são produzidos com os 5 conhecidos processos de fundição e injeção, frequentemente é necessário prever na parte de fundição ou injeção compartimentos ocos, por exemplo, canais, para meios de refrigeração ou lubrificação. além disso, uma desenformação de uma peça fundida ou injetada pode ser dificultada por contradesmoldes. em ambos os casos, são apropriados como espaços de correspondentes espaços ocos especialmente núcleos solúveis. como dispositivo para a disposição de suporte livre de um núcleo solúvel por solventes líquidos no molde de um dispositivo de fundição é proposto, segundo a invenção, que o dispositivo é ao menos um tubinho de suporte (3), o tubinho de suporte (3) tem uma parte (5) cilíndrica reduzida e essa parte (5) cilíndrica reduzida encaixa no núcleo (1) a ser suportado e suporta o núcleo.device for the support of cores in metal components, which are employed in the construction of machines especially in motors, pumps, compressors or power plant installations, and are produced with the known 5 casting and injection processes, it is often necessary to provide in part casting or injection hollow compartments, eg channels, for cooling or lubricating means. furthermore, unmolding of a cast or injected part may be hampered by counter molds. In both cases, they are suitable as spaces of corresponding hollow spaces, especially soluble nuclei. As a device for the free support arrangement of a liquid solvent soluble core in the mold of a foundry device it is proposed according to the invention that the device is at least one support tube (3), the support tube (3) has a reduced cylindrical part (5) and that reduced cylindrical part (5) fits the core (1) to be supported and supports the core.
