| PROBLEM TO BE SOLVED: To provide a device for molding a sand core which permits correspondingly adapting to a plurality of types of mold, enabling replacement of a mold to be facilitated to mold a sand mold efficiently.SOLUTION: A mold 2 is set up to a filling plate 14 of a sand tank 12 in which foamed sand S is stored. The foamed sand S is compressed by a compressing mechanism 13 to fill a cavity C of the mold 2 through filling ports of nozzles 15, and a sand core is molded. The filling ports of nozzles 15 are each formed of a straight hole, and viscosity of foamed sand S prevents gravity fall from the filling ports. In the filling plate 14, there is arranged a plurality of nozzles 15 beforehand corresponding to a plurality of types of mold 2 which have different arrangements of filling passages 5, and, when the mold 2 of one is set up, then the filling ports of any of the nozzles 15 are connected to the filling passages 5 of the mold 2, while unconnected filling ports are closed by a junction face 19 of the mold. In this way, it is enabled to replace a mold 2 without replacing the filling plate 14, thereby effecting efficient molding of a sand mold. | ||||||

| <P>PROBLEM TO BE SOLVED: To provide a die structure for molding a core and a method for positioning a vent plug with which the vent plug can surely be positioned and held to the normal position on the die for molding the core. <P>SOLUTION: The vent plug 8 is positioned in the height direction by abutting the opening hole part end surface 13a of the vent plug 8 on the criterion surface 15 of a height adjusting member 9 set to the vent plug fitting part 4 in an upper die 1 of the die for molding the core. At the same time of this positioning, the vent plug 8 is positioned on the criterion surface 15 by internally contacting the bottom part 12 in the based part 10 of the positioning member 5 with the opening hole part 13 of the vent plug 8. Therefore, to the upper die 1, the vent plug 8 can be positioned at high precision. <P>COPYRIGHT: (C)2010,JPO&INPIT | ||||||

| PROBLEM TO BE SOLVED: To manufacture optical element and parts of high accuracy. SOLUTION: A pre-shaped die is manufactured by machining and polishing a superalloy essentially consisting of tungsten carbide as a blank to a desired shape, then coating the surface thereof with silicon as a protective layer by a plasma enhanced CVD process, and further, coating the surface thereof with a chromium nitride of 1 μm in thickness. The shape of the manufactured pre- shaped die or the shape of a sample manufactured by the same is measured and the shape correction rate of the pre-shaped die 30 for a lower die is determined from the error of the manufacture. Further, the lower die forming surface 301 of the pre-shaped die 30 for the lower die is subjected to correction by etching in such a manner that a desired accuracy is obtained therein, by which the die is perfected. The optical elements and parts are manufactured by using such die. COPYRIGHT: (C)2003,JPO | ||||||

| PURPOSE: To easily execute takeout of a gypsum mold without embedding a pattern for forming mold in the kneaded gypsum by setting the pattern for forming the mold in a flask and making projection of the top part of the pattern for forming the mold from the flask top surface. CONSTITUTION: The pattern 6 for forming the mold is set in the flask 8 and the top part of the pattern 6 for forming the mold projects from the flask 8 top surface. The top part 72 of the pattern 6 for forming the mold is constituted of a pattern 7 for feeder head. By connecting the pattern 7 for feeder head as fittable/detachable to the pattern 6 for forming the mold, at the time of filling up the kneaded gypsum in the flask, the pattern for forming the mold does not be embedded in the kneaded gypsum. Further, by connecting the pattern 7 for feeder head as fittable/detachable to the pattern 6 for forming the mold, at the time of taking out the gypsum mold, at first only the pattern for feeder head can be taken out and the takeout of the gypsum mold can be easily executed.

| PURPOSE: To obtain a gypsum mold containing only a little blow hole by setting a pattern for forming disk wheel in a flask, connecting a guide member on top face of the pattern for forming the disk wheel and filling up kneaded gypsum through the guide member. CONSTITUTION: The pattern 6 for forming the disk wheel is set in the flask 8 and the guide member 7 is connected on the top face of the pattern 6 for forming the disk wheel and the kneaded gypsum P is filled up in the flask 8 through the guide member 7. The kneaded gypsum P is poured in almost center part of the guide member 7. As this top forms spherical projecting shape, the kneaded gypsum P flows down this top face as radial shape and goes along the side face of the guide member 7 and further, the surface of the pattern 6 for forming the disk wheel and fills up into space P in the flask 8 without containing blow hole under almost lamina flow.

| PURPOSE:To exactly and easily insert cores into holes of prescribed molds by the constitution in which the cores can be inserted into said holes while a drag flask of a swiveling receiving plate is raised and rotated on the outside of a molding section. CONSTITUTION:A base plate 14 is raised by a lifting cylinder 12 and the bottom surface of the drag flask 6' is received by a rotary receiving plate 17 at the top end of a revolving shaft 16 of a rotating machine 15 on the top surface. The bottom surface of the flask 6' is engaged and disengaged by the pins of receiving bars 10, 10'. The machine 15 operates in said position and the plate 17 rotates the flask 6' while rotating at a low speed or at every 90 deg.. An operator inserts the cores successively into the mold holes on the top surface of a casting mold 18 of the flask 6' under rotation. The machine 15 stops and the plate 14 descends when the insertion of the cores ends upon rotation of the flask 6' by one turn. The flask 6' is then received by the bars 10, 10'. The swiveling receiving plates 3 turns backward again at 180 deg. and starts mating of the mold 18 inserted with the cores. | ||||||

| PURPOSE:To form quickly a casting mold at a low cost and to reduce man-hour for molding by packing molding sand into a molding flask and curing the same, then machining the resulting sand block thereby forming the casting mold. CONSTITUTION:A sand block 12 formed by packing sand in a molding flask 11 and curing the same is machined with a cutting tool 24, then the removed sand is discharged instantaneously through a discharging hose 29 onto a sand discharging conveyor by the synergistic effect of the evacuation by a vacuum suction device 27 and the high speed rotation of a spiral conveyor 22. Since a pattern is not required, the need for storing the pattern is eliminated and a considerable reduction in space, maintenance and control expenses and cost is achieved. | ||||||
