Abstract (en)
[origin: EP3456431A1] The present invention relates to a mold pin for manufacturing a tube yoke, capable of rapidly manufacturing a tube yoke provided with a spline on a tube part through a forging step while preventing distortion involving a twisted shape of the spline. To this end, the mold pin for manufacturing the tube yoke, according to the present invention, is provided with a spline part on the outer circumferential surface thereof to form the spline on the inside of the tube part of the tube yoke comprising the tube part and a yoke part, wherein a land part protruding along the outer circumferential direction is formed on the spline part corresponding to one side in the lengthwise direction of the mold pin.
