This utility model relates to the field of auxiliary devices for blow molding machines, in particular to a mold clamping mechanism for an extrusion blow molding machine platform, comprising a bottom mold frame, a hydraulic drive cylinder, a front cylinder base, a rear cylinder base, a front mold, a rear mold, a front push rod, a rear push rod, a mounting base, a synchronization mechanism, a front connecting assembly and a rear connecting assembly. The front push rod and the rear push rod are rotatably fixed on the bottom mold frame. The hydraulic drive cylinder is rotatably connected to the front push rod through the front cylinder base, and rotatably connected to the rear push rod through the rear cylinder base. A sliding rail is arranged on the bottom mold frame, the front mold and the rear mold are both fixed on the mounting base, and the mounting base is slidably mounted on the sliding rail. By adopting the utility model, the overall structure is simple, the multi-stage structure disperses kinetic energy, and the optimized support assembly and connecting assembly are used for stress elimination, prolonging the service life of the mold plates, preventing the deformation of the front and rear mold plates, and improving production efficiency.
