摘要： An extruder includes a cylinder, a screw built in the cylinder, a dehydration cylinder block provided in the middle of the cylinder and discharging moisture that is separated from a resin material supplied into the cylinder. The dehydration cylinder block has a structure in which plate-shaped members each having an opening are arranged in a long-axis direction of the cylinder, a screw passing through the opening. Surface roughness of mutually opposing surfaces of the plurality of plate-shaped members is rougher than surface roughness of an inner wall of the cylinder.

摘要： An injection piston drives a screw. An injection hydraulic cylinder drives the injection piston and is partitioned into first and second chambers. A first oil discharge port is disposed in the injection hydraulic cylinder to be blocked by a piston part when the piston part of the injection piston advances to a pressure-holding switching position, and discharges hydraulic oil from the second chamber. A second oil discharge port is disposed in the injection hydraulic cylinder to be capable of discharging hydraulic oil from the second chamber regardless of the position of the injection piston. The injection piston has first and second members. The joint of the first and second members is disposed at a position separated from an end of the piston part on a side of the second chamber by a predetermined distance.
