: There is a mold clamping stroke generating device that further interposes a guide bar to make the movable surface plate slide back and forth toward the fixed plate.
The tie bar is slidably passed through the fixed plate, the other end is screwed to the movable end surface plate, and a hot runner manifold is provided between the fixed plate, the movable surface plate, and the movable end surface plate, respectively. In order to configure a stacked mold that slides, guide bars and tie bars are installed on both sides of the fixed platen and the supportable plate so that they can slide freely. A fixed plate is interposed at the center 62 so that when the mold is clamped, the other side is opened, and the left and right movable surface plates and the end movable surface plate are connected to guide bars as appropriate.
