After that, the hydraulic rod 17 is started. The hydraulic rod 17 pushes the third mounting plate 5 and the molding plate 12 along the optical axis 3 toward the first mounting plate 2 through the slider 8 and the spring 9. When the third mounting plate 5 contacts the mounting bracket 13 on the first mounting plate 2, the molding plate 12 is just at the front end of the screw extruder body 1.
