PRECISION CASTING METHOD AND DEWAXING AUXILIARY MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a method for suppressing damage of a casting mold by improving fluidity of a molten wax model on a runner forming part in a dewaxing process of a precision casting method.;SOLUTION: A method for suppressing damage of a casting mold includes: a wax model manufacturing process (A) for manufacturing a wax model 20 which includes a runner part 20b having a wax outlet part 20a filled with filler 22 and a product model 20c connected to the runner part 20b; a casting mold forming process (B) for forming a casting mold 40 so as to cover an outer surface of the wax model 20; a filler removing process (C) for removing the filler 22 from a wax outlet part 20a of the wax model 20; and a dewaxing process for heating and melting the wax model 20 from which the filler 22 is removed and discharging molten wax from the casting mold 40 to an external part.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
