The utility model discloses a mold clamping structure of an injection blow molding machine for processing plastic bottles, comprising a base. A fixed mold is arranged on the top side of the base, a movable mold is arranged above the fixed mold, two fixed blocks are fixedly installed on the top side of the base, the same installation plate is fixedly installed between the two fixed blocks, a rotating seat is fixedly installed on the top side of one fixed block, and a rotating pressure rod is rotatably installed on the rotating seat. The utility model has the beneficial effects that: in the utility model, during the blow molding processing of plastic bottles, the movable mold and the fixed mold need to be clamped first. A worker presses the rotating pressure rod downward, can drive a lower pressure rod to move downward under the action of an adjusting sliding hole and a sliding connecting block, the lower pressure rod moves downward to drive the movable mold to move downward, and the movable mold moves downward to drive an L-shaped sliding block to slide in a sliding groove, so as to drive the movable mold and the fixed mold to be clamped. Only the rotating pressure rod needs to be pressed downward, and the mold clamping is relatively simple.
