摘要： In a method of operating an injection molding machine of a type having an injection plunger for pushing melt from an injection space anteriorly of an injection plunger into an injection mold, a plasticizing screw of an extruder is continuously operated to continuously feed melt through a melt channel into the injection space. A passage through the melt channel is closed to allow backup of melt backwards into the extruder, and the injection plunger is moved forward to inject a shot amount from the injection space into the injection mold.

摘要： An injection unit for an injection molding machine includes a plasticizing unit in the form of an extruder, a plunger-type injection device, which can be connected to the injection molding machine by an injection nozzle. The plunger-type injection device defines an injection space. The extruder has a forward portion which is connected to the injection space by a melt through channel in which a shutoff valve is disposed. The extruder is operated continuously and includes one or more plasticizing screws, wherein the extruder is configured in such a way that the backup length can expand backwards into the extruder, when the shutoff valve is closed.

摘要： In a compounder-type injection molding machine having an extruder for continuously producing a melt and at least one injection device is fluidly connected to the extruder to receive melt, a reservoir is provided which is in fluid communication with the extruder as well as with the injection device for temporary storage of melt. In order to maintain a pressure at a desired level at the outlet of the extruder, a pressure sensor is provided for ascertaining a melt pressure state downstream of an outlet of the extruder. The pressure sensor outputs a signal, commensurate with the melt pressure state, to a control unit for activating a drive in the reservoir or a drive in the injection device in response to the signal according a predetermined algorithm.

摘要： An injection unit for injection molding machines includes an extruder as plasticizing unit and a plunger-type injection molding device that can be coupled to the injection molding machine by an injection nozzle. The plunger-type injection molding machine has an injection plunger, wherein the area in front of the injection plunger forms an injection space which is connected to a forward end of the extruder by a melt channel, with a shutoff valve disposed in the melt channel. The extruder can be continuously operated and has one or more plasticizing screws for plastification, wherein the extruder is so configured that a backup length is able to increase backwards into the extruder, when the shutoff valve is closed.
