METHOD FOR DIVIDING CHANNEL CORE

摘要

PURPOSE: A method for dividing a channel core is provided to cause no deviation and make easier to coat a bonding agent since a core is unevenly coupled by forming a projection and a concave part on a parting plane of the core and dividing the same. CONSTITUTION: The method for dividing a channel core where a bar and a plate meet is characterized in that the core is divided in a manner that a parting plane of the plate becomes a concentric arc of the rod while maintaining the shape of the bar. A projection(200) and a concave part(100) are formed on their respective concentric arcs of the parting plane and then divided.
