The present invention relates to an extrusion die for extruding a tread made of chimney rubber for preventing static electricity, and particularly, to a variable extrusion die for changing the position of chimney rubber for preventing static electricity of a tire, wherein the die can extrude the tread by adjusting the position of a final die when the position of chimney rubber is changed on a cap tread. The extrusion die for extruding chimney rubber for preventing static electricity of a tire has a final die (3) which is assembled to a preformer die (1) and is fixed by a stopper (2). The stopper (2) connected to an actuating rod (5) of a hydraulic cylinder (4) is installed to fix the final die (3) which is assembled into a guide channel groove (1a) of the preformer die (1). |
