ッドのスムーズな昇降が出来ない等の問題がある。In the above-described molding apparatus in the prior art, the crank press has a problem that the positional accuracy of the bottom dead center of the slide is not stable due to thermal displacement or the like, and the hydraulic press uses oil. Therefore, there is a problem that it is not possible to cope with a clean working environment including installation space of the hydraulic unit and noise. Further, a molding apparatus using an AC servomotor as a drive source has problems in high-speed positioning accuracy, ensuring safety during a power failure, and the like. Furthermore, in a molding device using a linear motor, a force acts on a guide device that guides the ascent / descent of the molding head by the magnetic attraction force of the linear motor due to the relationship between the mounting position of the linear motor and the guide device.
The gap between the movable slider and the magnet plate that constitutes the linear motor changes, and the thrust of the linear motor is not stabilized, or the guide device is deformed and the frictional resistance increases, so that the forming head can move up and down smoothly. There are problems such as being unable to do so.
