<p>The invention relates to a new hydraulic press for low pressure casting provided with a press unit (6) assembled on a plane which shifts horizontally on a couple of guide rails or slides (5) integral with the vertical supporting frame in order to get the place over the die (3) accessible from above. In this way the movement of the dies is easier since it takes place by means of a crab or a crane (7). The guide rails or slides projecting beyond the vertical supporting frame of the press unit can rotate both horizontally and vertically in order to reduce the bulk of the press. The press unit shifts laterally carrying the whole die to be removed and lodging said die on a fastened plane (9), a shifting plane or a lift truck (10) arranged next to the press. It is possible to apply a new die both with the press unit which takes the die from the lateral plane or the lateral lift truck, and with a crab which can lay the die on the bedplate while the press unit is removing the previous die.</p> |
