20110036529 | CASTING DIE DEVICE - A casting die assembly which does not produce any burrs includes a stationary die and a movable die that are clamped in a condition in which a slide core is caused to move toward a center of a movable die, and a back surface of a protrusion of the slide core contacts a stopper section provided on a frame section. The stopper section is subjected to the pressure applied to the slide core during a casting operation. Since the stopper section is provided on part of the frame section, which is integrally formed on the periphery of the stationary die, the stopper section is not caused to retreat or deform by the casting pressure and as a result, the slide core is not moved and burrs are not produced. | 02-17-2011 |
20120118524 | CORE DIE WITH VARIABLE PINS AND PROCESS FOR PRODUCING A CORE - A core die is provided. The core die includes a first half and a second half where a cavity is formed between the two. Pins are arranged on the halves and the pins are replaceable. By virtue of the modular inner structure of a core die, the core die may be matched to the desired changes of the core, by small changes, more quickly and more easily than would be the case if the core die had only one part or if the pins were a fixed component of the core die halves. | 05-17-2012 |

20090308563 | CORE PIN UNIT FOR DIE CASTING - A core pin unit for die casting mounted inside a movable mold including a core die and a core holder for forming a hole at a mold is provided, which comprises a core pin body being inserted into both the core holder and the core die, a locking screw mounted at the rear end of the core pin body inserted into the core holder, a spring interposed between the core pin body and the locking screw in the core holder; and a cooler mounted at the rear end of the core pin body. The core pin unit prevents a core pin body from bending due to a load of a molten metal introduced and from being damaged by vibration thereof. | 12-17-2009 |
20110024073 | APPARATUS FOR MANUFACTURING ROTOR FOR ROTATING ELECTRIC MACHINE - An apparatus for manufacturing a rotor for a rotating electric machine. The apparatus includes a movable mold and a stationary mold, and a cavity is formed between those molds. The movable mold includes a rotor core holding portion holding a rotor core, and a core arranging portion arranging a core removably. The core includes a base core and a plurality of split cores. The base core is equipped on its outer circumference with a remedy face, which is positioned in the inner circumference of the open end portion of a boss portion and extends in a mold-release direction of a casting, thereby blocking the deformation of the open end portion at the parting time. | 02-03-2011 |
20110056648 | HOLLOW-CAST CASTING - A hollow-cast casting is provided, which includes at least one core opening that is caused by the production technique and which has a closure device that closes the core opening. The closure device can be inserted into the core opening axially in relation to the core opening and provides at least one surface region which, in axial projection in relation to the core opening, can be made to abut a surface region of the casting that is facing toward the casting. The surface region lies radially outside a cross-sectional area predetermined by the core opening. | 03-10-2011 |
20110132566 | CASTING TOOL AND METHOD FOR PRODUCING WORKPIECES CAST FROM LIGHT-METAL ALLOYS - The invention relates to a casting tool for producing workpieces from light metal alloys. The system includes a positioning element, a core part, a first mold part structured to carry the positioning element and be movable toward the core part, and a core part support structured to support the core part. The system also includes at least one stop structured to limit movement of the front mold part toward the core part and to allow the positioning element to be introduced into the core part, whereby the positioning element holds the core part in a predetermined position for casting. | 06-09-2011 |
20130068415 | MOLD FOR CASTING A WORKPIECE THAT INCLUDES ONE OR MORE CASTING PINS - A mold for casting a workpiece that includes a casting shell, a casting core and casting pin that supports the core within the shell. The casting shell includes an interior shell surface. The casting core is located within the shell, and includes a sidewall extending between a first core surface and a second core surface. The casting pin includes an intermediate segment connected between a first support segment and a second support segment. The intermediate segment contacts the sidewall. The first support segment extends from the first core surface to a first side of the interior shell surface. The second support segment extends from the second core surface to a second side of the interior shell surface that is opposite the first side. | 03-21-2013 |
164341000 | Having auxiliary means for locking assembled parts in place | 2 |
20150047800 | MOULD FOR PRODUCING CAST PARTS - A mold for production of cast parts, having two mold parts in the form of mold plates, which mold parts arc movable with respect to each other from an open position into a closed position, wherein the mold parts in their closed position define a mold cavity which may be filled with liquid casting compound and in their open position enable removal of a cast part which has solidified by at least partial cooling, and are lockable in their closed position by means of a locking device which joining the two mold parts so as to be releasable, and which mold parts may also be swung, wherewith in the closed position the locking device produces the locking of the mold plates with the stipulation that the locking pressure is maintained. The locking device has an energy storage means with a gas pressure spring for maintaining the closing pressure which presses the mold plates together after they have initially been pressed together. | 02-19-2015 |
20160184887 | CLAMPING DEVICE AND MOLDING APPARATUS - The clamping device has a fixed platen, a moving platen which is movable in an mold opening and closing direction relative to the fixed platen, a tie bar which bridges the fixed platen and the moving platen, a pullout drive device which give to the tie bar a driving force making the tie bar move to the back side of the fixed platen, and a support mechanism which is provided separately from the pullout drive device and support the load of the tie bar when moving the tie bar. | 06-30-2016 |
