This invention discloses a contouring deflashing device for a gallon barrel injection blow molding machine, comprising: an upper and lower adjusting plate, a left and right adjusting plate, and a cutting plate. The upper and lower adjusting plate is connected to the moving arm of the injection blow molding machine, and the left and right adjusting plate is connected to the upper and lower adjusting plate. A fixed plate is provided at each of the left and right ends of the left and right adjusting plates. A rotating shaft is rotatably mounted between the two fixed plates and connected to a drive mechanism. The cutting plate is fixed to the rotating shaft. A contouring blade is provided on one side wall of the cutting plate, and an arc-shaped plate extending towards the contouring blade is provided on the cutting plate.
