摘要： The invention relates to an injection unit for an injection moulding machine for processing plastics, or other plastifiable materials, with a screw (1), provided with a rotating drive, by means of a rotating motor (2), comprising a stator (3) and a rotor (4) and which may be displaced in the axial direction in a screw cylinder to execute the injection function, by means of several electrical linear motors (6), each comprising a primary piece (7), functioning as stator and a linearly displaceable secondary piece (8a, b, c). The linear motors (6) are assembled to give a group (9) in the form of a housing with the secondary pieces (8a, b, c,) of the linear motors (6) arranged parallel to each other and the secondary pieces (8a, b, c) of the linear motors (6) connected to the screw (1) for drive purposes. According to the invention, the rotating motor (2), fixed to the screw (1) in the axial direction, is arranged within the housing-like group (9) and with the stator (3) thereof coupled to the secondary pieces (8a, b, c) of the linear motors (6) in the axial direction.

摘要： The invention relates to a linear drive device for opening and closing molding tools and for applying a closing force thereon, especially molding tool halves of a plastic molding machine. Said device is comprised of a spindle drive acting upon the molding tool, a first spindle nut for opening and closing the molding tools and a piston/cylinder unit for applying a closing force. In order to provide a linear drive device for opening and closing molding tools, especially molding tool halves of a plastic molding machine, which enables fast opening and closing of the molding tools and energy-optimized application of the closing force to the molding tools, the piston/cylinder unit (113) acts upon the molding tool by means of a second spindle nut (108).

摘要： The invention relates to an injection unit for an injection molding machine, especially for plastics, comprising a screw that is connected to a first actuator provided for turning and to a second actuator provided for effecting an axial movement. The first actuator (21) is an electric motor, and the second actuator (31) is a pressure bellows that can be filled with a gas by means of a filling device (51), whereby the volume of the pressure bellows (31) can be altered by adjusting elements (32).
