This invention features a second-stage clamping mechanism, avoiding the impact of air leakage and pressure loss on the clamping force. This utility model invention relates to the technical field of injection blow molding hollow forming machines, specifically a mold opening and closing device for a fully electric injection blow molding machine. It includes a fixed mold mounting base, a main pull rod, a movable mold mounting base, and a support base. The left and right ends of the fixed mold mounting base are slidably connected to the main pull rod, and the upper and lower ends of the two main pull rods are respectively fixedly connected to the movable mold mounting base and the support base. The lower surface of the fixed mold mounting base is equipped with a mold opening and closing mechanism, which consists of a driving component and a mold opening and closing push-pull component. The mold opening and closing push-pull component includes a mold opening and closing component, and both sides of the mold opening and closing component are equipped with auxiliary arm pull rods for guiding and limiting. This utility model invention uses a novel mold opening and closing mechanism to control mold opening and closing, completely solving the oil leakage problem of cylinder-driven systems.
