This utility model relates to the field of blow molding and mold clamping equipment, in particular to an improved mold clamping mechanism for an extrusion blow molding machine, comprising a telescopic arm and a limiting member. The telescopic arm consists of a hinge joint, a driven rod, a driving rod, a rotating head and a screw arranged sequentially from right to left. The two ends of the driven rod are hinged to the hinge joint and the driving rod respectively, one end of the rotating head is hinged to the driving rod, and the other end of the rotating head is fixedly connected to the screw. The limiting member comprises a travel limiting plate, a pulling plate, a supporting plate and a guide rod arranged sequentially from right to left. The hinge joint is fixedly connected to the pulling plate, the screw penetrates the supporting plate and is slidably connected thereto, and the two ends of the guide rod penetrate the pulling plate and are fixedly connected to the travel limiting plate and the supporting plate respectively. The utility model facilitates the replacement and adjustment of molds and avoids the problem of easy oil leakage and pollution in hydraulic types.
