FIG. 1 is a longitudinal sectional view showing an embodiment of the present invention;
Figure 2 is a partially enlarged vertical cross-sectional view of the head of the extrusion rod in Figure 1, with Figure A having a rounded head shape and Figure B having a concave pressure receiving surface on the head. Fig. 3 is a vertical sectional view showing the screw and extrusion rod in Fig. 1 when they have been moved back together; Fig. 4 is a longitudinal sectional view showing the extrusion rod in Fig. 1 when it has been pushed out to the runner section. It is a longitudinal cross-sectional view showing a state. FIG. 5 is an explanatory diagram schematically showing an injection molding machine and showing actually measured values of pressure loss during injection as a line diagram. Figures 6 and 7 are conventional examples;
FIG. 6 is a longitudinal sectional view of an injection molding machine provided with a separate injection cylinder, and FIG. 7 is a longitudinal sectional view of an injection molding machine using an inclined rod. 1...Injection cylinder, 2...Screw, 3...
