<p>PURPOSE: A stopper for a coolant flow channel of a mold is provided to completely prevent coolant from leaking by obtaining an adhesive force the adhering to a flow path through expanding an expansion member when the expansion member is pressurized by coupling a base member with a coupling member. CONSTITUTION: A stopper for a coolant flow channel of a mold comprises a base member(100), a coupling member(300), and an elastic expansion member(200). A latching protrusion unit is positioned between the base member and the coupling member by inserting into the elastic expansion member in a cylindrical shape. The elastic expansion member is expanded to the outside by being pressurized between a settling stepped unit and a coupling inclined unit when the coupling member is coupled with the base member.</p> |
