A die gap offset adjustment device for a blow molding machine belongs to the technical field of blow molding machinery, including a pressure ring with a die insertion hole at the center, a die orifice, a die sleeve and a support ring. The device further comprises an outer sleeve, a vertical die gap adjustment mechanism and a horizontal die gap adjustment mechanism. A die actuating rod support base is arranged on the upper part of the die orifice, provided with mounting holes for vertical and horizontal adjustment connecting rods. The support ring is equipped with a first support arm and a second support arm. The outer sleeve is sleeved on the outer wall of the lower section of the die sleeve and provided with avoiding holes for adjustment rods. The vertical gap adjustment mechanism is mounted on the first support arm, and the horizontal gap adjustment mechanism is supported on the second support arm. The device enables stepless adjustment of the gap between die orifice and core, meeting the process requirements for wall thickness control of curved hollow plastic parisons.
