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