CA 2082977
An injection molding machine comprises a carrier block, which contains a plasticizing cylinder and to which hydraulic advance-retract cylinders and hydraulic injecting cylinders are axially coupled. The cylinder barrel of each advance-retract cylinder carries an injecting piston for cooperating with an injecting cylinder barrel which surrounds the advance-retract cylinder barrel. Because each advance-retract cylinder barrel is integrally formed with a radial flange, which constitutes the injecting piston for cooperating with the associated injecting cylinder barrel, the injecting unit will be able to withstand high pressures and its parts can yet economically be made in series.
