    • PROBLEM TO BE SOLVED: To provide an injection nozzle constituted so as to prevent a stringing phenomenon at the time of ejection of a molded product easy to occur in the molding of an optical element such as a lens or the like.
      SOLUTION: A small diameter short projection 11a is provided to the leading end of the injection nozzle 1 and a first small diameter orifice 13a is formed to the projection. Further, a second small diameter orifice 13b, which is smaller than a nozzle main body orifice 13 and has a diameter larger than that of the first small diameter orifice 13a, is formed corresponding to the transition part 11b between the projection and a nozzle main body part 11. When the small diameter short projection is cooled by a mold 2, the resin material 4 in the vicinity of the leading ends of the first and second small diameter orifices 13a and 13b is cooled to the temperature of the mold to be solidified and, since the solidified resin 5 is cut at the boundary of the first and second small diameter orifices at the time of ejection of the molded product, stringing is prevented certainly.

    • PROBLEM TO BE SOLVED: To provide a molded article taking out machine the arm of which swings by a link mechanism, and which discharges the molded article taken out from a die and a spool or the like while sorting them into both sides of an injection-molding machine.
      SOLUTION: This molded article taking out machine is equipped with the arm 41 which swings on the top of a strut 1, an angle regulating plate 31 which swings together with the arm 41, and a fluid cylinder 21 which is attached to the proximal part of the strut 1. The molded article taking out machine constitutes a link by connecting a fitting 24 for fixation at the distal end of a piston rod 23 of the fluid cylinder 21 with the angle regulating plate 31. In addition, the fluid cylinder 21 is constituted into one which stretches to three locations of a longest location, an intermediate location and a shortest location. Then, the molded article taking out machine is constituted in such a manner that when the piston rod 23 is located at the intermediate location of the fluid cylinder 21, the angle regulating plate 31 and the fitting 24 for fixation are connected under a state wherein the arm 41 is located at the intermediate reference location while approximately vertically hanging downward.

      SOLUTION: The mold clamping device for the injection molding machine supports a fixed platen and a movable platen at substantially center height positions in the vertical direction symmetrically from both sides by the support members, then supports a back platen at a substantially center height position in the vertical direction symmetrically from both sides by the support member, and places the lower end faces of the support members slidably on the machine base. All the support members of the platens are formed of material with a low thermal expansion coefficient. The fixed platen, the movable platen and the back platen are fitted, at the bottoms thereof, to a reference member positioned at the center position in a transverse direction orthogonal to a mold opening/closing direction. In addition, it is preferable to attach heat insulating plates to the side faces of the fixed platen and movable platen, and it is also preferable to support a driving device elastically.
