Abstract
PURPOSE: The captioned pouring method of providing firm contact free from component segregation and casting defects by performing freezing while exerting static pressure at the time of pouring bearing alloy to the preheated bearing base metal and freezing the same.
CONSTITUTION: A core die 2 for pouring, e.g., white metal and a support base 3 are integrally combined on the inner side of bearing base metal 1 and, if necessary, they are fixed by way of a packing 4 or the like. Molten white metal 6 is poured into this assembled mold and pressure is exerted thereto from above by a pressing die 7 by using a hydraulic apparatus or the like until the molten metal lowers to below the temperature at which the molten metal perfects freezing. After the freezing, the core die is separated by a core descending drive mechanism 8.
