Abstract
PURPOSE: To improve the heat resisting property of casting molds so that the dimensional accuracy of a low-melting alloy cating and the disintegratability of molds may be improved, by filling to a model with refractory solid particles coated with a thermoplastic resin under a heated state, and by covering them with water-glass after the particles are solidified.
CONSTITUTION: A binding agent which contains ≥ kind of usual thermoplastic resins, such as methacryl resin, polyethylene resin, polypropylene resin, etc., is used for this purpose. Moreover, silica sand is used as a refractory solid particles. The silica sand is mixed to the above mentioned binding agent after it is heated to a temperature higher than the melting point of the above mentioned resins. After molds or cores are formed, water-glass is penetrated or coated.
