<p>A locally pressurizing type injection molding machine includes a stationary die (12) and a movable die (14). An ejector pin (26) extends through the movable die (14), with its tip end facing a cavity and its trailing end fixed by an ejector plate (31,32). A vibrating/pressurizing pin (35) extends through the movable die (14) and the ejector plate (31,32), with its tip end advanceably and retreatably facing into a resin passage in correspondence to a molded product portion to be worked, and with its trailing end fixed by the vibrating/pressurizing plate (36,37). A vibrating/pressurizing actuator (41) is disposed in rear of the vibrating/pressurizing plate (36,37), so that the vibrating/pressurizing can be advanced through the vibrating/pressurizing plate (36,37), and the ejector pin (26) can be advanced through the vibrating/pressurizing plate (36,37) and the ejector plate (31,32), both by operating the vibrating/pressurizing actuator (41). <IMAGE></p> |
