An orifice gap offset adjusting device for a blow molding machine belongs to the technical field of blow molding machinery. It includes a pressure ring with an orifice insertion hole at the center, an orifice, a die sleeve and a support ring. The device is characterized by further comprising an outer sleeve, a vertical orifice gap adjusting mechanism and a horizontal orifice gap adjusting mechanism. The upper part of the orifice is provided with an orifice actuating rod support seat, which is drilled with mounting holes for vertical and horizontal adjusting 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 avoidance holes for vertical and horizontal adjusting rods. The vertical gap adjusting mechanism is mounted on the first support arm and connected to the orifice actuating rod support seat, while the horizontal gap adjusting mechanism is supported on the second support arm and also connected to the support seat. It meets the process requirement of adjusting the parison wall thickness of curved hollow plastic products.
