Abstract
The invention relates to a barless mold closing device for injection molding machines, which absorbs the mold closing and opening forces via a C-shaped machine frame, in which plate bending is minimized by asymmetrical internal die forces and eccentric opening forces and the load on the die guides and in which it is possible to automatically compensate for non-parallelisms at the die parting line. The solution calls for the fixed die mounting plate 2 and/or the end plate 4 to be supported in two horizontal bearing axes 9, 10 and 11, 12 above and below the axis of injection 7. The lower bearing axes 10, 12 are connected to the fixed die mounting plate 2 and/or to the end plate 4 via elastically deformable components 13 in such a way that these components are connected to the elastic deformation of the machine frame 1, so that there is no angular deviation from the vertical position of the mounting surfaces 2.1, 3.1. In each case, the end plate 4 or the die mounting plate 2 can also be mounted in a uniaxial fashion in the machine frame 1 and thus be disconnected from the deformation of the machine frame 1.
