A blow pin mechanism for a hollow blow molding machine relates to the technical field of hollow blow molding machines. A connecting seat is installed between a blow pin seat plate and a blow pin support, a blow pin oil cylinder is mounted on the blow pin support, an electronic ruler transition plate is mounted on the blow pin seat plate, and an electronic ruler is fixedly connected to the blow pin support via an electronic ruler seat plate and vertically connected to the electronic ruler transition plate. A blow pin mounting seat is fixed at the bottom of the blow pin seat plate, the upper end of a blow pin is mounted on the blow pin mounting seat, and the lower end is inserted into a guide rod mounting seat. A guide rod is installed between the guide rod mounting seat and the blow pin support, and the blow pin seat plate is slidably connected to the guide rod. The blow pin mechanism uses an electronic ruler to accurately monitor the stroke of the blow pin oil cylinder, providing dual protection with an induction switch, reducing oil cylinder wear, prolonging service life and lowering maintenance costs.
