INJECTION MOLDING MACHINE, PLASTICIZING MOVEMENT DEVICE, AND NOZZLE TOUCH METHOD

摘要

In an injection molding machine, a hydraulic actuator and a hydraulic pump are arranged close to each other to make a hydraulic pipe as short as possible so as to improve maintenanceability and improve reliability of a hydraulic drive part. The injection molding machine has one movable part configured to be movable with respect to a body frame. The hydraulic actuator and the hydraulic pump unit are fixed to the movable part. The hydraulic pump unit supplies a generated fluid pressure to the hydraulic actuator. The hydraulic pump unit and the hydraulic actuator are connected by a hydraulic passage provided to the movable part. The hydraulic actuator, the hydraulic pump unit and the hydraulic passage are moved with a movement of the movable part.
