The utility model discloses a plastic blow molding machine, comprising a mold body. A mold groove is formed in the middle of the surface of the mold body, and a cooling mechanism is arranged inside the mold body. The cooling mechanism comprises a cooling chamber, connecting pipes, heat dissipation plates and through grooves. A cooling chamber is arranged inside the mold body on one side of the mold groove. A plurality of connecting pipes are uniformly and fixedly arranged at the upper end of the cooling chamber, and a plurality of hollow heat dissipation plates are uniformly and fixedly arranged at the upper ends of the connecting pipes. A plurality of through grooves are uniformly formed in the outer surfaces of the connecting pipes at the heat dissipation plates. The utility model has a good use effect. The cooling mechanism enables automatic circulation of cooling fluid through phase change without complex circulating pipelines and installed pumps, greatly simplifying the device structure.
