| 261 | Method for measuring strength of mold and marking in mold and device therefor | JP10715397 | 1997-04-24 | JPH10296391A | 1998-11-10 | YORITSUNE MANABU; HAYASHI ETSUJI; YAMAMOTO SHIGEAKI |
| PROBLEM TO BE SOLVED: To efficiently measure the strength of a mold and at the same time, to attach a mark for casting necessary information of a casting on the cavity surface in the mold. SOLUTION: A load cell 15 as a pressure sensor is fitted to a pressing member 14 attaching the mark corresponding to the necessary information on the cavity surface 2a in the mold 2. Reaction force loaded on the pressing member 14 at the time of attaching the mark on the cavity surface 2a with the pressing member 14, is detected with the load cell 15. In an arithmetic means 16, the strength of the cavity surface 2a in the mold 2 is obtd. with a calculation based on the detected value of the load cell 15. The mark for casting the necessary information on the casting is efficiently attached to the cavity surface 2a in the mold 2 and at the same time, since the strength of the casting 2 can efficiently and accurately be measured with the load cell 15 fitted to the pressure member 14, this method can remarkably contribute on the improvements of the productivity of the molds 2 and the quality of the casting.

| 262 | Method and device for attaching individual marking on green sand mold | JP8332493 | 1993-04-09 | JPH0639489A | 1994-02-15 | BUENDERIN BUAIMAN |
| PURPOSE: To enable marking on a heterogeneous roughened surface by attaching an identificating individual mark on a sand surface in the cavity part of a mold. CONSTITUTION: A mark is attached on a green sand mold. At this time, the mold is compacted at the cavity part of the mold so as to transfer the mark to a casting from the sand surface with casting operation. The mark is attached without contacting, or with contacting in some case. In an apparatus, mold pressing device is arranged and a type wheel printer for attaching the mark is arranged, and one or more of marking needles for attaching the mark, are used. The attachment of the mark on the sand surface is executed by using an ultrasonic wave or a laser beam without contacting. In this way, the marking can be changed at the speed of a computer. | ||||||

| 265 | Preventing method for explosion of water drop under mold weight | JP4557281 | 1981-03-30 | JPS57160550A | 1982-10-02 | SATOU SADAO; OOTANI MASASHI |
| PURPOSE:To prevent the damaging of a mold and a core and to eliminate the cause for defective castings by coating oil on the bottom surface of a weight placed on the mold thereby reducing the evaporating and explosive force of the water drops stuck on the bottom surface of the weight. CONSTITUTION:During transporting of a weight 1, the oil 3 in a pressure vessel 4 is coated on the bottom surface of the weight 1 by operating an oil coating gun 6. The oil supply part of the gun 6 communicates with the inside of the oil 3 in the vessel 4 through a pipe 7 and the injection pressure supply part of the gun 6 communicates with a compressed air source through a piping 8. Since the oil 3 is coated on the bottom surface of the weight 1 placed on the mold during charging of molten metal to the mold in this way, the evaporating and explosive force of the water drops stuck on the bottom surface of the weight is reduced. | ||||||

| Provided is a core grasping method of grasping a core using a core grasping apparatus. The core grasping apparatus includes grasping devices respectively having expandable and contractible grasping parts. The core includes holes, and at least one of the holes has an inside diameter that decreases in the opposite direction from a direction of a turning moment occurring on the core. The core grasping method involves, when grasping the core, expanding the grasping parts inserted in the holes so as to bring the grasping parts into contact with inner walls of the holes of the core, and grasping the core and applying a force that suppresses the turning moment to the core. | ||||||

| A method for the production of castings which are permanently provided with readable information. An identification element, which has an information surface, provided with information, and a casting surface which is assigned to the casting and also provided with information, is arranged on a casting mould surface assigned to a mould cavity of a casting mould so that the information surface is covered, while the casting surface is exposed in the mould cavity. A metal melt is poured into the mould, so that, during casting or solidification of the metal melt, a firmly bonded, form-fit or force-fit connection of the identification element to the casting is produced. The information on the casting surface is reproduced in the manner of a stamp on surface of the casting. The casting is then removed from the mould and fettled. | ||||||

| The present invention is a multipart system and method for using cloth filters in automated vertical molding. The system includes a filter setter, a filter print plate and a filter back shelf. The filter setter removably mounts to a mechanical arm and releasably carries at least one cloth filter between upper and lower jaws. The filter print plate mounts to a ram plate while the filter back shelf mounts to a swing plate. During vertical molding, the ram plate and swing plate compress sand to create a mold. The mounted filter print plate creates at least part of a print aperture into which the filter setter inserts the cloth filter. The apertures created by the filter print plate and the filter back shelf support the cloth filter during the founding process. | ||||||

| 277 | METHOD OF FORMING A CASTING MOLD PATTERN | US15201698 | 2016-07-05 | US20180009025A1 | 2018-01-11 | Scott Minadeo |
| A method of forming a casting mold pattern that includes a core comprises mounting the core in a fixture such that the core is free of flexing imposed by the fixture. Material is removed from and/or added to a first and/or second mounting surface of the core. The core is then positioned in a die, and wax is conducted into the die to form the pattern. The amount of material removed from the first and/or second mounting surface is such that the core will be within a predetermined range of acceptable positions when the core is in the die with the first mounting surface engaging a first core locating surface of the die end with the second mounting surface engaging a second core locating surface of the die. The range of acceptable positions is determined relative to an ideal position of an ideal core. | ||||||
| 278 | Furnace assembly | US14834584 | 2015-08-25 | US09808859B2 | 2017-11-07 | Donald Joseph Selmi |
| A furnace assembly for dewaxing investment casting molds includes a housing having a top and a bottom and sides and extends along an axis to define a cavity. A plurality of tiles are supported in a spaced relationship with the bottom of the housing and define a pair of lower chambers for directing the wax vapors out of the cavity. A plurality of trays having apertures are supported by the tiles for moving molds through the housing. Chimneys connect to the lower chambers and a passageway is defined by the tiles for evacuating the wax and wax vapors from the cavity to the lower chambers and out through the chimneys. A pair of lower burners extends into the lower chambers for igniting wax vapors in said lower chambers. The heat from the lower chambers radiantly heats up portions of the furnace assembly that are disposed above the lower chambers. | ||||||
