Abstract
A system of injection-moulding machine closing units is provided. In addition to two closing units of a first kind and third kind in a standard program, the closing units having closing forces F1 and F2, a further closing unit of a second kind having a closing force F1 is provided. The closing unit of the second kind forms an intermediate variable and is formed from components of the closing units of the first and third kind provided. The platens and the support plate with the dimensions of the closing unit of the third kind (closing force F2) and the toggle lever mechanism of the closing unit of the first kind (closing force F1) and the drive thereof are combined with one another. The articulated levers of the toggle lever mechanism of the closing unit of the second kind are hinged to the support plate and movable platen at a greater distance from the axis of symmetry than the articulated levers of the toggle lever mechanism of the closing unit of the first kind. The articulated levers themselves are identical. At the same time, the crosshead of the closing unit of the second kind is larger in the direction of the articulated levers of the toggle lever mechanism than the crosshead of the closing unit of the first kind such that the toggle lever mechanisms of the two closing units have the same kinematics.
