PURPOSE:To provide the compactness, etc. of a device by providing an arm and cylinder device to a drawing car, pressing an oscillating claw by a cylinder device to the upper part of the inside surface of a casting and pressing a stationary claw to the lower part of the inside surface. CONSTITUTION:A frame 29 which oscillates to a rotary metallic flask 4 side is provided to the drawing car 2 and the arm 32 is disposed via a bearing 31 to the frame 29. The outside surface of a stationary claw 34 is curved and formed to conform to the inside surface of a pipe 6 and is attached to the top end of the arm 32. An open/shut claw 37 is freely oscillatably attached to one end of a link member 36 and the outside surface thereof is curved and formed to conform to the inside surface of the pipe 6. The detained arm 32 and the claw 37 are inserted horizontally into the rotary metallic mold 4 and an air cylinder 16 is actuated to open the claw 37. The claw 34 presses simultaneously the inside surface of the pipe 6 to grip the pipe 6 when the claw 37 is pressed to the inside surface of the pipe 6 by the reaction of said actuation. The drawing device is made compact by such method. |
