Abstract

núcleo à base de sal e método para sua produção a invenção refere-se a núcleos que são inseridos nas peças de trabalho feitas de metal no processo de fundição sob pressão, para deixar livres as cavidades previstas nas peças de trabalho quando os moldes são preenchidos com a massa fundida, devem atender elevadas exigências com relação à sua estabilidade dimensional e facilidade com a qual elas podem ser removidas das cavidades. por essa razão, é proposto de acordo com a invenção que o material de núcleo seja completamente solúvel em água e possa ser removido das peças de trabalho com água sem deixar qualquer resíduo e que os núcleos sejam feitos de sais em um molde não-líquido e os materiais adicionais possam ser fabricados através do processo de disparo automático de núcleo utilizando pressões adequadamente ajustadas para a composição do material de núcleo para atuar sobre o respectivo material com o qual os ditos núcleos são circundados.Salt-based core and method for its production The invention relates to cores that are inserted into metal-made workpieces in the die casting process, to clear the cavities provided in the workpieces when the molds are filled with the melt must meet high demands regarding its dimensional stability and the ease with which they can be removed from the cavities. For this reason, it is proposed according to the invention that the core material is completely water soluble and can be removed from water workpieces without leaving any residue and that the cores are made of salts in a non-liquid mold and the additional materials may be manufactured by the automatic core firing process using pressures suitably adjusted for the composition of the core material to act upon the respective material with which said cores are encircled.
