This invention relates to the technical field of demolding devices, and more particularly to a high-efficiency demolding device applied to injection blow molding machines. It includes a mold body, which has multiple through holes. Splice rods are installed in the through holes, with the ends of the splice rods flush with the inner wall of the mold body. Process air holes are provided inside the mold body, and these process air holes are connected to the multiple through holes. The outer wall of the splice rods seals the openings of the process air holes within the through holes. An air inlet pipe is installed on the outer wall of the mold body and is connected to the process air holes. By providing through holes and process air holes in the mold body, pneumatic demolding of the injection molded product can be achieved, ensuring even force distribution on the product and preventing damage to the outer wall due to concentrated stress, thus protecting the product and improving the demolding effect.
