PURPOSE: A press dies of trimming equipment is provided in which the punch is positioned at center of the die as suppressing abrasion between die and punch as much as possible. CONSTITUTION: In a press dies of trimming equipment comprising a die(100) on which a plurality of die blades(110) are formed with being spaced apart from each other in an equal distance, and a punch on which a plurality of punching bars(210) inserted into die grooves (H1,H2) between the die blades(110) are formed with being spaced apart from each other in an equal distance, wherein the punching bars(210) comprise cutting part(211) for cutting dambar (D) and guide part(212) projected from the cutting part(211) to free end of the cutting part(211), the press dies of trimming equipment is characterized in that a distance (h2) between the die blades(110) and guide part(212) is shorter than a distance (h3) between the die blades(110) and cutting part(211), and the punching bars(210) are arranged at the middle of the die grooves (H1,H2) between the die blades(110), wherein the cutting part(211) and guide part(212) of the punching bars(210) have an equal width, and width of the die groove (H1) corresponding to the guide part(212) is narrower than width of the die groove (H2) corresponding to the cutting part(211), and wherein width of the guide part(212) is wider than that of the cutting part(211), and die grooves corresponding to the guide part(212) and cutting part(211) have an equal width.
