<p>The present invention relates to an apparatus for producing plastic parts interspersed with reinforcing fibers, with a mixing chamber (20) for producing a mixture of chemically reactive polymer components, with an outlet chamber (38), which is arranged downstream of the mixing chamber and in which a cleaning ram (28) in which a fiber conveying channel (32) is formed is guided in a reciprocatingly movable manner. The invention is characterized in that the end face of the cleaning ram is provided with a die (34), through which the fiber conveying channel (32) extends and arranged on the outer circumference of which there is an annular groove (40), which is at a distance from the end of the die (34) and can be positioned in such a way that, in a first working position, a flow connection between the mixing chamber (20) and the annular groove (40) is formed and, in another working position of the cleaning ram (28), the flow connection between the mixing chamber (20) and the annular groove (40) is interrupted and in that at least one die channel (42), preferably a plurality of die channels (42), is/are formed between the annular groove (40) and the outlet-side end of the die (34), said channel(s) opening at the end face into the outlet chamber (38).</p> |
