Embodiment Construction

[0027] exist figure 1 In , a closing unit 4 is shown schematically in side view, which together with an injection unit (not shown) forms a molding machine 100 , in particular an injection molding machine. The closing unit 4 has a frame 11 , on which the fastening clip template 6 is fastened. The movable clamping template 5 can move along the frame 11 and be installed on the frame 11 so as to be linearly movable. A mold half 7a and 7b of the forming tool 7 is respectively mounted on the two clamping plates 5 and 6 . Clamping formwork 5 and 6 pass through by a plurality of beams 12, wherein in figure 1 Only one beam is shown in . The beam 12 can be detachably fastened on the movable clamping plate 5 through the locking device 13 .

[0028] In the region of the fixed clamping plate 6 , a piston 14 is arranged at the end of the cross member 12 , which is mounted displaceably in a cylinder 15 arranged on the fixed clamping plate 6 . The piston 14 and the cylinder 15 together f...

Abstract

The invention relates to a method for operating a molding machine, wherein the molding machine has a first electric drive unit, a second electrohydraulic drive unit and an intermediate circuit connecting the two drive units. Kinetic energy is released during the molding cycle when the first drive unit (1) brakes, the released kinetic energy is transmitted via the intermediate circuit (3) to the second drive unit (2) and this transmitted energy is at least temporarily directly The ground is used without temporary storage for pre-accelerating the second drive unit (2). Furthermore, the invention relates to a molding machine, in particular an injection molding or die-casting machine, comprising an electric first drive unit, an electrohydraulic second drive unit, an intermediate circuit connecting the two drive units and a control or Adjustment of the control or regulation unit of the molding machine.

Description

technical field [0001] The invention relates to a method for operating a molding machine, wherein the molding machine has a first electric drive unit, a second electrohydraulic drive unit and an intermediate circuit connecting the two drive units. Furthermore, the invention relates to a molding machine, in particular an injection molding or die-casting machine, comprising an electric first drive unit, an electrohydraulic second drive unit, an intermediate circuit connecting the two drive units and a control or Adjustment of the control or regulation unit of the forming machine. Background technique [0002] When operating a forming machine, a large amount of energy is generally required to perform the various movements and to provide high forces, for example when closing forces are applied. This usually also leads to excess energy, which has to be dissipated again. In order to be able to dissipate such excess energy during braking, for example in the case of electric servo...
