ABSTRACT:
In an injection molding unit for use in an injection molding machine for processing synthetic materials a coupling device is applied for coupling the feed screw with a spindle by means of an axial locking device subject to the rotational movement. The locking elements of the axial locking device are received in a seat and are provided with several threaded bolts, which are connected to first bore holes of the spindle and are inclinedly arranged opposite to a plane laid through the axis. That way, in spite of its simple construction, a coupling device easy to maintain and reasonable with respect to the price is created.
