A closure unit for an injection molding machine, comprises a movable tool tensioning plate (2), which can be moved using a spindle (6) to close the tool, and a unit that holds the tool in the closed position. The closure holding tool has a nut (12) which is in contact with the spindle, and a tipping element (26) is supported on the nut. A closure unit for an injection molding machine, comprises a movable tool tensioning plate (2), which can be moved using a spindle (6) to close the tool, and a unit that holds the tool in the closed position. The closure holding tool has a nut (12) which is in contact with the spindle, and a tipping element (26) is supported on the nut. When the nut moves in the closure direction, the tipping element moves into a clamping position, where the tensioning plate is supported on the spindle or on a frame of the closure unit (1). A number of tipping elements are located at a distance from the spindle axis. The clamping nut is moved into position using an electromagnet. Clamping members are located between the clamping sleeve and the nut, and are moved into a clamping position by rotation of the nut. The unit has a clamping sleeve and a clamping housing, which are pretensioned against a stop on the side of the nut.
