徴とする鋳型造型機における湯口棒。[Scope of Claim for Utility Model Registration] A pair of casting flasks are stacked on both sides of a pattern plate on which a model is integrally formed, and a compression plate is fitted into the outer opening of each flask. A mold making machine that forms a predetermined molding space in the flask by covering the flask, and molds a predetermined mold by compacting the molding sand filled in the molding space using the compression plate. , one of the compression plates is provided upright and its tip is brought into contact with the pattern plate to form a sprue in the mold, and is expandable and expandable with a predetermined biasing force. The sprue rod is a sprue rod that has a hollow structure with an internal space, consisting of a plurality of cylindrical bodies fitted together in a telescoping manner so that they can expand and contract, and the leading edge of the cylindrical bodies. By forming an ejection hole in the protruding end surface of the cylindrical body located at the cylindrical body and providing an air supply means for supplying compressed air to the internal space, the compressed air can flow from the internal space to each of the cylindrical bodies. What is claimed is: 1. A sprue rod for a mold making machine, characterized in that the sprue rod is made to flow out between the fitting surfaces of the sprue, and to be ejected through the spout hole.
