Problems solved by technology

[0007] The disadvantage of all these configurations is that, although the parallelism of the plates is partially improved, no correction is made for offsets due to the simultaneous tilting of the plates clamped by the movable and fixed dies

Embodiment Construction

[0027] figure 1 The closure unit 1 shown comprises a crank lever mechanism 9 and four beams 8 (only two beams 8 are visible since this is a side view). Both the end plate 10 and the movable mold clamping plate 3 are mounted slidingly, the linear guides 12 for the movable mold clamping plate 3 and the rollers 13 for the end plate 10 being shown here only by way of example.

[0028] The fixed mold clamping plate 2 is supported by a support element 4 , wherein the fastening between the support element and the fixed mold clamping plate is correspondingly provided by three fastening screws 11 . This bearing is arranged above the machine axis X, which is ideal for preventing tilting and thus offsetting between the mold halves during acceleration of the movable mold clamping plate. The fastening element 4 is fastened on the frame 5 by bolts.

[0029] The recess 7 between the fixed mold clamping plate 2 and the machine frame 5 ensures that the fixed mold clamping plate 2 is only sup...

Abstract

A closure unit of an injection molding machine has a fixed mold mounting plate, a moveable mold mounting plate, and at least one mounting element for mounting the fixed mold mounting plate to a machine frame. The at least one mounting element upon accelerations and decelerations of the moveable mold mounting plate to reach the closed position allows such movements of the fixed mold mounting plate relative to the machine frame that rotations and / or movements transversely relative to a machine axis of the fixed mold mounting plate relative to the moveable mold mounting plate are substantially prevented.

Description

technical field [0001] The invention relates to a closure unit of an injection molding machine having the features of the preamble of claim 1 . Background technique [0002] As a result of the acceleration or deceleration of the movable clamping plate, undesired movements, in particular tilting and vibrations, of the movable mold clamping plate, of the fixed mold clamping plate and possibly of the end plate are usually caused. Especially in the presence of transverse beams, the tilting and vibrations are also transmitted by the different plates to each other. This is particularly detrimental when the movable mold clamping plate is braked, since in the event of a collision of the two mold halves the non-parallelism would lead to wear and even damage. Another problem lies in the production of components requiring extremely high precision. The mentioned tilting of the plates produces, for example, an offset such that the two mold halves are no longer precisely positioned rela...
