An injection molding unit for processing synthetic materials has a changing unit provided with several connecting bores, transversally lockable separately controllable stoppers, for optional connection to supply lines. The stationary connecting bores are arranged at a basic body radially around a central feed opening, which is at least partially bordered by the stoppers when they are out of operation. Consequently the necessary space requirement as well as the effort for running in the stoppers can be reduced.
