A reciprocating blowing mechanism for a plastic extrusion blow molding machine consists of a plastic extruder and a bottle blowing system. The barrel of the extruder is connected to a die head, and the bottle blowing system comprises a mold, a mold clamping mechanism, and a blowing mechanism. The bottle blowing system is installed on a rotating workbench equipped with a support frame; the mold and the mold clamping mechanism are mounted in the support frame, and the blowing mechanism is installed on the support frame or directly on the workbench. The blow pin cylinder of the blowing mechanism reciprocates along a straight line between the center and the periphery of the rotating workbench. Thus, when the mold is fed from the die head, the blow pin cylinder retracts toward the center of the workbench to avoid collision between the blow pin cylinder and the die head, enabling the entire machine to automatically complete extrusion and blow molding production.
