Claims

[Scope of Claim for Utility Model Registration] An apparatus for molding a vanishing model by filling a mold with vanishing model beads, the mold comprising: a body molding mold for molding a body of the vanishing model; a thin-walled part molding mold that is continuous with the main body molding mold and molds a thin-walled part of the disappearing model, and the thin-walled part molding mold disappears into a thin-walled part molding space therein. 1. A molding device for a vanishing model for casting, comprising a movable member configured to narrow the thin-walled portion molding space after being filled with model beads.
