The utility model relates to the technical field of blow molding machine heads, in particular to a head lifting mechanism of an automatic hollow blow molding machine, comprising a lifting cylinder and a blow molding machine body. The lifting cylinder is fixed to the blow molding machine body, a fixing frame is fixedly mounted on one side of the top of the lifting cylinder, a mounting plate is fixedly mounted in the middle of the fixing frame, and a discharge rod is fixedly mounted at the bottom end of the mounting plate. In the utility model, by providing a lifting cylinder, discharge rods and a mounting plate, the lifting cylinder is controlled to move the blow molding head body upward, and the blow molding head body drives the clamped plastic upward. When the plastic reaches the ends of the two discharge rods, the plastic is blocked by the two discharge rods, while the blow molding head body continues to move upward, so that the two discharge rods strip the plastic stuck on the blow molding head body, and the plastic falls off to realize separation, facilitating the removal of the plastic. The utility model solves the problems in the prior art that plastic is not easy to be removed from the head and needs manual removal, which is still inconvenient for blow molding.
