MOLD FOR PRECISION CASTING, AND METHOD FOR PRODUCING SAME

摘要

A mold for precision casting which is used to produce a casting, the mold having a core which has a shape corresponding to the hollow section in the interior of the casting, and an outer mold which has a shape corresponding to the outer circumferential surface of the casting, wherein the outer mold comprises: a prime layer (101A) which is formed on the inner circumferential surface from a slurry film obtained by drying a mold slurry for precision casting comprising monodispersed aluminum superfine particles having a diameter of 1.0 μm or less; and a multi-layered back-up layer (105A) which is formed on the outside of the prime layer (101A) by forming multiple back-up layers (104) obtained by forming and drying slurry layers (102) formed from the mold slurry for precision casting, and stucco layers (103) obtained by attaching a stucco material on the slurry layers (102).
