Abstract
resumo patente de invenção: "processo para a produção de núcleos salinos para a produção de peças de trabalho por técnica de fundição". a presente invenção refere-se a um processo para a produção de núcleos para a produção de peças de trabalho por técnica de fundição, especialmente núcleos anelares para moldagem de canais de refrigeração em êmbolos ou partes de êmbolos, a serem produzidos por técnica de fundição, de motores de combustão, sendo que os núcleos são produzidos por técnica de fundição, na medida em que um sal fundido, empregado como material de fundição, com alta velocidade de fluxo e com pressão limitada é inserido em uma cavidade de uma disposição de ferramenta de moldagem, cavidade esta que corresponde ao núcleo a ser produzido, respectivamente aos núcleos a serem produzidos, sendo que a velocidade de fluxo e as temperaturas do sal fundido e das peças moldadas são ajustadas de tal modo que uma solidificação do sal fundido só ocorra após o enchimento total da cavidade, e a pressão é limitada a um valor máximo, no qual uma deformação das peças moldadas permanece abaixo de um valor de tolerância.Patent specification: "Process for the production of saline cores for the production of workpieces by casting technique". The present invention relates to a process for producing cores for the production of die casting workpieces, especially annular cores for molding cooling channels in pistons or piston parts to be produced by casting technique, The cores are produced by casting technique, as a molten salt employed as a casting material with high flow velocity and limited pressure is inserted into a cavity of a molding, which cavity corresponds to the core to be produced, respectively to the cores to be produced, and the flow rate and temperatures of the molten salt and molded parts are adjusted such that a solidification of the molten salt only occurs after cavity, and the pressure is limited to a maximum value at which a deformation of the molded parts remains below a tolerance value.
