Second legs each have: a proximal end joining the second end portion; a main body portion; and a free distal portion. | 12-10-2009 |
| 20110000635 | MASTER MOLD FOR DUPLICATING FINE STRUCTURE AND PRODUCTION METHOD THEREOF - A method and master mold comprising a metal support layer and a fine structure pattern comprised of a glass or ceramic material, wherein the pattern support layer is formed of a first material having a relatively low grinding speed, and the fine structure pattern is formed of a layer of a second material having a grinding speed higher than that of the material of the pattern support layer. | 01-06-2011 |
| 20120234512 | ONE-PIECE MANUFACTURING PROCESS - A method of making a turbomachine part, wherein the method can include machining a blank into a base having blades extending therefrom, the blades defining a channel therebetween. The method can also include forming a bridge constructed from refractory material in the channel between the blades, and forming a cover on the tops of the blades and over the channel, such that the base, the blades, and the cover form a single substantially homogenous turbomachine part once the bridge is removed. | 09-20-2012 |
| 20130264021 | Method and Apparatus for Machining Molding Elements for Foundry Casting Operations - A method for machining a sand molding element, comprising: inserting at least one hollow center body having an internal cavity in a predetermined position in a casting flask; filling the internal cavity of the hollow center body with unbonded sand; filling the casting flask with bonded sand to obtain a sand block; machining a mold cavity in the sand block; and emptying the internal cavity from the unbounded sand. There is also provided a method for machining a molding core from a sand block, comprising: providing a core base member having a concave upper surface; forming a sand block on the core base member with a lower surface of the sand block resting on the concave upper surface; and machining the molding core into the sand block, the molding core having a convex lower surface complementary to the concave upper surface of the core base member. | 10-10-2013 |
| 20140326425 | METHOD AND APPARATUS FOR MACHINING MOLDING ELEMENTS FOR FOUNDRY CASTING OPERATIONS - A method for machining a molding core from an aggregate material block, comprising: positioning the aggregate material block on a rotative base member; and rotating the base member and simultaneously machining the aggregate material block into the molding core. There is also provided a method for forming a casting mold including a molding core and a foundry casting core comprising: a core body having at least one convex shaped core print. The method comprises: providing at least one molding element having a mold cavity with at least one core-print pocket defined in a top side of the molding element; forming the molding core having at least one convex shaped core print; and inserting the molding core in the mold cavity with the at least one convex shaped core print engaged in a respective one of the at least one core-print pocket. | 11-06-2014 |
| 20150034265 | METHOD OF CATCHING OVERFLOW OF A LIQUID FLUID UTILIZED TO CAST A COMPONENT - A method of catching overflow of a liquid fluid utilized to cast a component is disclosed. Sand is compacted to form a mold. A cutter of a cutting device is in a disengaged position spaced from a top surface of the mold when the cutting device is in a first position and the cutter is in an engaged position engaging the top surface of the mold when the cutting device is in a second position. The cutter is actuated when the cutting device is in the second position and the cutter is in the engaged position to remove sand from the top surface to define a recess therein to catch overflow of the liquid fluid. The recess is spaced from an opening. At least one blocking mechanism, blowing mechanism and adjustment mechanism is utilized to assist the cutting device. | 02-05-2015 |
| 20150321246 | PATTERNLESS SAND MOLD AND CORE FORMATION FOR RAPID CASTING - A method of creating a sand mold for rapid casting, including the steps of determining a mold shape, providing a generally uniform thickness layer of sand, curing at least a portion of the layer of sand, machining the cured portions of the layer of sand based on the desired mold shape, and repeating the layer-forming, curing and machining steps until the sand mold is complete. Another aspect includes a machine for creating the sand mold having a build envelope defined by side walls, a movable build platform and at least one movable tool assembly, the movable tool assembly having a single or plurality of tools chosen from the group consisting of a sand dispenser, a sand leveling device, a curing device, and a machining device. | 11-12-2015 |
| 20160151830 | METHOD OF CATCHING OVERFLOW OF A LIQUID FLUID UTILIZED TO CAST A COMPONENT | 06-02-2016 |
