| 20120241117 | MOLDING MACHINE AND MOLDING PROCESS - Disclosed is a molding machine for simultaneously making upper and lower molds with cope and drag flasks, a matchplate, upper and lower squeezing boards, and a lower filling frame. This machine also includes a cylinder for raising and lowering the lower squeezing board, a driving mechanism that includes pneumatic and hydraulic piping systems for driving the cylinder using an air-on-oil system, and a controller for controlling the driving mechanism. The drag flask, the matchplate, the filling frame, and the lower board define a lower molding space, while the matchplate, the upper board, and the cope flask define an upper molding space such that the controller controls the driving mechanism to drive the cylinder at a low pressure. The lower squeezing board is raised to squeeze the molding sand for simultaneously making the two molds such that the controller controls the driving mechanism to drive the cylinder at a high pressure. | 09-27-2012 |

| 20130299115 | PROCESS FOR MANUFACTURING A SALT CORE BY ISOSTATIC COMPACTION FOR PARTS IMPLEMENTING SUCCESSIVE FOUNDRY AND FORGING OPERATIONS - A process for manufacturing a salt core to be introduced into a foundry mold by casting of parts made of aluminum, aluminum alloy, or light alloys obtained according to casting operations in order to form a foundry preform. The core is a salt powder and undergoes for its shaping an isostatic compression of the salt powder. The core obtained with the desired shapes is then introduced into the foundry mold to make the form to be obtained, and the shape resulting from the foundry operation is a preform including the salt powder core obtained by isostatic compression. The preform is then forged with its core at a pressure ranging between 600 and 700 MPa to obtain the final form of the product to be obtained, and the core subsequently removed. | 11-14-2013 |
| 20140110076 | METHOD FOR THE MANUFACTURE OF CASTING MOLDS AND A DEVICE FOR REALIZING THE SAME - A method of pulsed-air compacting of mold-sand in combination with compacting by compression supplements the pulsed-air compacting of the mold-sand by an operation of re-compacting the mold-sand by pressing which is performed with the pattern plate containing the patterns by the plate moving inside the cavity of the filling frame in the direction of the latticed pressing element which is subjected to a counter-pressure force corresponding in its value to the prescribed level of the half mold compaction. The method is realized with a device in which the pattern plate containing the patterns is mounted with the possibility of a reciprocal motion inside the cavity of the filling frame, and the pressing cylinder is mounted with the possibility to apply a force against the movable pattern plate. | 04-24-2014 |
