Embodiment Construction

[0027] The deformations shown in the figures are calculated and exaggerated by means of numerical simulations, since they would not otherwise be recognizable. Typical deformations are on the order of hundredths of a millimeter at mechanical parameters of 500KN to 1000KN maximum closing force. In addition to image 3 All linear guides are hidden in the middle and outside. This helps at a glance.

[0028] exist Figure 1a The frame 2 , the movable mold clamping plate 3 and the fixed mold clamping plate 5 can be seen first. The mold halves 11 of the injection molding mold are arranged between the mold clamping plates 3 , 5 .

[0029] The frame 2 has two side panels 4 on which guide supports 6 are arranged. In this exemplary embodiment, the side plates 4 together with the guide supports 6 are formed as deformation elements 10 .

[0030] as by Figure 1a As can be seen in , the resulting symmetrical deformation of the deformation elements 10 is no problem for positioning the m...

Abstract

A closing unit for molding machine comprises a rack (2) and a movable mold clamping plate (3) having at least one bearing support (9). The frame has at least one side plate (4), on which at least one guide support (6) is fixed. The at least one bearing support (9) can be linearly movably supported on the guide support (6) along a machine axis (X). The at least one the guide support (6) constitutes a deformable element (10). The deformable element is configured to be more flexible than the at least one bearing support (9) in a horizontal deforming direction (Z) transverse to the machine axis (X), and the force led into the force leading rack (2) under a closing force through the deformation of the movable mold clamping plate (3) and / or a fixed mold clamping plate (5) is compensated at least partially through deformation.

Description

technical field [0001] The invention relates to a closing unit of a molding machine according to the features of the preamble of claim 1 and to a molding machine with such a closing unit. [0002] A molding machine is to be understood here to mean an injection molding machine, an injection molding machine, a press or the like. For the sake of simplicity, reference is often made below to injection molding machines, wherein the statements made in the description of the prior art also apply to molding machines in general. Background technique [0003] In the development of the closing unit of an injection molding machine, major attention has been paid to the guiding accuracy of the movable mold clamping plate, since this particularly significantly affects the plate parallelism and thus the product quality. In this process, precise linear guides, for example linear guides with roller chains, are used for the guidance of the movable mold clamping plate. [0004] However, this h...
