ABSTRACT:
A clamping unit for an injection molding machine includes a fixed platen, a support platen, and a moving platen which is arranged between the fixed platen and the support platen for back and forth movement. An opening and closing mechanism constructed as crank drive having at least one crank disk is provided to effect a back and forth movement of the moving platen in relation to the support platen, with the crank disk rotatable by a drive mechanism. A first connecting rod links the crank disk to the support platen, and a second connecting rod links the crank disk to the moving platen, wherein at least one of the first and second connecting rods is articulated in eccentric relationship to the crank disk. A pulling means extends between the support platen and the fixed platen to allow a buildup of a clamping force between the fixed platen and the moving platen.
