き防止機構。 In an injection molding machine, there are two plates 7 between the sprue bush 3 and the nozzle 5, each of which has a blade-like tip and is bent into a shape that fits the tip of the nozzle 5, and which meet at the sprue bush. As a result, the curved part 10 at the tip of the nozzle 5 comes into contact with the inclined surface 9 of the bent part of the plate 7, and the two plates 7 are pushed open by the incoming pressure, and the nozzle 5 joins to the sprue bush 3, causing the resin to flow out. When the injection is completed and the nozzle 5 retreats, the two plates 7 slide along the curved part 10 of the nozzle 5 under the pressure of the spring 8 and meet, cutting the stringy part of the resin. A threading prevention mechanism for an injection molding machine.
