This invention relates to the technical field of clamping structures, and more particularly to an automatic clamping and mold locking structure applied to injection blow molding machines. It includes an outer frame, with a lower mold and an upper mold positioned within the outer frame. The lower mold is fixed to the outer frame, and the lower and upper molds together form a complete mold. It also includes multiple first mounting plates, which are installed side-by-side on the side wall of the upper mold. A U-shaped outer plate is provided on the outside of the first mounting plates, and a guide column is fixed inside the U-shaped outer plate. The guide column passes through the first mounting plate and is slidably connected. A spring is fitted onto the outer wall of the guide column. By using a clamping and locking method to secure the lower and upper molds, the relative position of the lower and upper molds can be easily fixed while ensuring they remain in contact. This prevents separation of the lower and upper molds during operation, ensuring product processing under relatively low contact pressure and preventing deformation or damage due to excessive mutual pressure between the lower and upper molds.
