摘要： A transport device includes a moving mechanism and a plate. The moving mechanism includes a pinion, a conversion mechanism, which converts vertical motion of an upper die assembly into rotational motion of the pinion, and a rack, which is moved as the pinion rotates. The moving mechanism is configured to move, when the rack moves from the top dead center position to a bottom dead center position, the plate to a position that is away from a die apparatus in a conveying direction and is below a conveying surface. The pinion includes a toothless portion that does not mesh with the rack when the rack moves between the bottom dead center position and a middle position that is between the top dead center position and the bottom dead center position.
