The invention discloses a shaping device for wood door machining in the technical field of wood door machining equipment. The shaping device comprises a base, a first fixing plate, a second fixing plate and movable plates. A plurality of wood doors are placed between the two movable plates, all movable lead screws rotate at the same time through a motor and a gear, the positions of the movable plates are adjusted according to the thickness of the wood doors, accordingly, the wood doors are extruded and shaped through side pressing plates, operation is simple, and shaping is convenient. The screw pitches of the movable lead screws are sequentially increased, and when the movable plates move to any position, the distances between the adjacent movable plates are the same, accordingly, the same-batch multiple wood doors the same in thickness are conveniently shaped at the same time, time and labor are saved, and the shaping efficiency is high. Upper pressing plates move along with the movable plates through movable grooves, sliding blocks and limiting plates, then, a guide rod drives connecting rods and the upper pressing plates to move downwards through lifting lead screws, accordingly, the side edges of the wood doors are shaped, and shaping is comprehensive. The shaping device is simple in operation and convenient to use, wood frames and nails are not needed, materials are saved, and the shaping effect is good.
