More Information
Summary:A two-platen injection molding machine with a stationary mold carrier plate and a movable mold carrier plate which are connected via tiebars having piston-cylinder units which build up and cancel the clamping force. At least one driving cylinder is arranged at the carrier plates for quick driving movement thereof. The tiebars are constructed as loose clamping pins forming the piston rod of the piston-cylinder units. The tiebars are guided through the movable mold carrier plate and the stationary mold carrier plate, and have a hydraulic high-pressure closing unit and a quick-locking mechanism mounted thereon external to the mold carrier plates. Elements are provided which detect the position of the movable mold carrier plate in a defined manner and control the quick-locking mechanism the closing unit, and the driving cylinder.
