Electric motor drive unit for an injection molding machine for processing plastics

An injection molding unit for an injection molding machine for processing of plastics materials and other plasticizable materials, such as powdery or ceramic masses, comprising

• a plasticizing unit that can be accommodated in the injection molding unit and in which there is provided a feed screw for conveying the plasticizable material into a mold cavity of an injection mold,
• an electromechanical dosing motor for rotating the feed screw when dosing the plasticizable material comprising a rotor and a stator,
• an electromechanical injection motor for axial movement of the feed screw relative to the plasticizing unit,
• wherein the injection motor comprises a spindle drive having a spindle and a nut cooperating therewith,
• wherein axes of the dosing motor and the injection motor are aligned with one another,
• wherein the spindle of the injection motor is axially and radially rigidly connected to the rotor of the dosing motor and the dosing motor is blockable in one direction of rotation by a free-wheel device mounted in a housing of the dosing motor.
