に構威している。(Port) Conventional technology Conventionally, cast products have a protruding sprue, and the sprue is cut by a crusher. Such a crusher has left and right expanding blades attached to the bottom of a cylindrical machine frame so as to be able to expand in the left-right direction, a hydraulic cylinder attached to the top of the machine frame, and a hydraulic cylinder arranged between the expanding blades by the cylinder. It is arranged to activate the core rod.
さらに、かかる破砕機は、芯棒の全体をテーパー状に形
成すると共に、左右の拡開刃の芯棒が接触する面をもテ
ーパー状に形或している。Further, in such a crusher, the entire core rod is formed into a tapered shape, and the surfaces of the left and right expanding blades with which the core rods come into contact are also tapered.

ーパー面が左右の拡開刃を外方に押し拡げることにより
、同湯口を破砕切断するようにしている。Then, when the core rod is lowered by the same hydraulic cylinder with the expansion blade applied to the sprue of the cast product, the tapered surface of the concentric rod pushes the left and right expansion blades outward, The sprue is cut by crushing.
（ハ） 発明が解決しようとする課題
ところが、かかる破砕機は、以下のような欠点を有して
いた。(c) Problems to be Solved by the Invention However, such a crusher had the following drawbacks.
すなイっち、破砕機は、芯棒と左右の拡開刃とをそれぞ

口の破砕作業を容易に行うことができなかった。The Sunaichi crusher has a core rod and left and right expansion blades each tapered, and the expansion blades are expanded by the lifting and lowering movement of the core rod. When the expanding blade is pushed apart by all sides of the rod, the movement of the core rod is not smooth due to friction between the surfaces of the concentric rod and the expanding blade, and therefore, the work of crushing the sprue is facilitated. I couldn't do it.
