Figure-8-shaped cable die and production method thereof

The invention discloses a figure-8-shaped cable die. The figure-8-shaped cable die comprises a die core, a die sleeve matched with the die core, and a material splitting cone connected with the die sleeve, wherein a channel between the die sleeve and the die core is a runner; a milling groove is formed in the discharge port end of the side sleeve; a circular discharge hole is formed in the discharge port end of the side sleeve; and an arc step is arranged between the outlet of the runner and the circular discharge hole. According to the figure-8-shaped cable die disclosed by the invention, a runner groove is milled in the outer surface of the die sleeve, after a circular hole is punched from the outlet of the runner to a straight section in the side sleeve, the outlet of the runner and thecircular discharge hole are transited through the arc step, and dead angles in the flowing channel are eliminated, so that the runner is streamline, and pigment extrusion is benefited; and an arc transition design is adopted
