The present invention relates to an oil-free slide unit for a mold. More specifically, as a slope pin slides back and forth in a straight line, a busing in contact and rubbed with the slope pin is formed into a cylinder shape, and in order to wholly and stably supports the cylinder and to facilitate the sliding operation of the slope pin, the oil-free slide unit for a mold can slide in one pair of slide blocks with guide rails (11) formed on each of the inner sides facing each other. The oil-free slide unit comprises a pair of slider (31) having a protruding part (31') which protrudes toward the guide rail; a housing block (400) having a circular bussing hole (410) formed in a lateral direction and a rectangular second slope pin hole (420) formed up and down; and a bussing (300) which is cylindrical in shape to be able to rotate by being inserted into the bussing hole (410) and has a first slope pin hole (310) penetrated by a slope pin (500) up and down. |
