Abstract
1341499 Toggle-mechanism for closing moulds KRAUSS-MAFFEI AG 19 April 1971 [11 April 1970] 26299/71 Heading F2K [Also in Division B5] A closing device for an injection mould carrier plate 2 is connected to a stationary supporting plate 1 by a pair of toggle levers 8, 9 which, in the «open» position (as shown), occupy an angle of less than 90 degrees, the toggle-lever joint being engaged by a driving unit 28 supported from the two plates by a pair of straps 10, 11 which take the counter-force, the arrangement being such that when the carrier plate is in this position the line of force of the driving unit through toggle-lever joint 25 forms an angle not greater than 70 degrees with the direction of closure of the carrier plate, so that the force applied has a component in the closing direction. Preferably this angle is less than 45 degrees. The supporting straps 10, 11 may be of different lengths, one being bent the fluid pressure cylinder of the driving unit being supported by a pivot 27 at the angle of the bend and the piston 33 being connected to the toggle-lever joint 25. The toggle-lever and the straps are preferably formed from parallel pairs of elements which interleave (Fig. 3, not shown) to provide a compact assembly. Further embodiments (Figs. 5 to 8a), describe double-toggle arrangements, some utilizing straight support straps either of different lengths or the same length, and with the driving unit connected to the bottom pair of toggle levers, or the top pair. In one arrangement (Fig. 8, 8a, not shown) the fluid-pressure cylinder is connected by its lower end to the support strap for greater compactness. The stationary supporting plate 1 can be adjusted along the rods 12 by bearing bushings 17 operated by gearing 19, 20.
