However, it is inconvenient to limit the front and rear directions of the die when the die is moved, which may easily cause the die to shift and fall, thereby affecting the upper die work. Moreover, due to the different electric screw presses used, the height of the upper die frame of the electric screw press is also different, which makes it inconvenient to move the die to a matching height, and thus has a small scope of application.
