摘要：PURPOSE:To obtain a metallic mold with a simple stage and in a short period for
production by casting a muddy mixture of a self-curing binder and aggregate onto a
pattern, applying a mold coating material on a casting mold obtd. by rapping after curing
of said mixture and charging molten metal into such casting mold. CONSTITUTION:A
pattern made beforehand to the same shape as the shape of a metallic mold 1 for a shell
mold of, for example, a cylinder with air cooling fins which has an intricate shape and is
required to have good surface skin and dimensional accuracy by using wood or the like is
disposed in a casting flask in order to manufacture said mold 1. A phenolic resin soln., a
polyisocyanate resin soln. and a basic catalyst for curing are added and kneaded to and
with aggregate of silica sand or the like having >=80 mesh AFS grain size index, whereby a
muddy mixture is prepd. The mixture is immediately cast on the pattern and after curing,
the pattern is rapped to obtain a casting mold. A mold coating material of flake graphite
and alcohol is uniformly coated multiple times on the inside surface of such mold. The
melt of gray cast iron is cast into the casting mold, and the obtained metallic mold 1 is
removed from the casting mold and is finished.
