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 a device for removing injection moulded parts from the mould of an injection moulding machine, especially for plastics, provided with a moveable and a fixed tool mounting plate. The inventive device comprises a drive unit which enables an actuating unit connected to a spindle (21) to be moved both towards and away from the mould in a linear manner. An engaging element (40) is also provided to enable the spindle (21) to be displaced axially. The invention is characterized in that a toothed disk (22) is secured to one end of the spindle (21), whereby the diameter thereof (D) is greater than the outer diameter (d) of the spindle (21). The invention is further characterized in that the toothed disk (22)corresponds to a tubular component (31)which can be driven by the drive unit (61)and which surrounds the spindle (21) in a free moving manner. The invention is also characterized in that the engaging element (40) is connected to the moveable tool mounting plate (11).
