For the production of clay casting molds, aas molding sand or similar Porminaaae it takes special time to fill the gate Molding sand in the box set but fashion, or hemming that Gießtriehtermodell or * - to insert the Gießtrichtermodelle and them to be removed after making the mold. For molding and semolina flow systems, dl «work more or less automatically is also this often requires special staff, loose (x spout models can also go Terloren *.

To this deficiency zn. remove * you have seen that or those (pouring models are attached to the underside of the press plate of the Forsrmasehis *. The molding takes place as «at the same time with the texthtening of the sand previously poured into the molding box ·

Your hiring also makes it possible to close this doorway. make it easier that the haum for the tt & er <L ± m aießtricht models in the molding sand gate is cleared for the impression U.9T models. For this purpose, according to the innovation, the pouring funnel model or models are provided with an axial bore and connected via this to a compressed gas line. With the help of an appropriately designed control system, a jet of compressed gas, ζ · Β · compressed air can be blown directly against each point at which the molding sand is to be molded into the molding sand, and thus slats can be released for the casting model.

The drawing shows an exemplary embodiment for a door direction in accordance with the innovation, and the model plate is drawn in vertical section with the molding box 3 set by the user three models 2 , above which the press plate 4 is located.

The molding box 3 is already filled with the sand 5, which is now to be sealed. This is done by moving the model plate 1 vx & the press plate 4 against each other under appropriate pressure, the wooden pressed bodies 6 penetrating into the molding box 5.
