[0005]
The present invention has been made in view of the above circumstances, and an object of the present invention is to remove various casting materials having different shapes from upper and lower molding flasks after a plurality of pouring, respectively. It is an object of the present invention to provide a method and an apparatus capable of taking out various kinds of the casting materials from the lower casting flask by a single device after the casting flask is lifted and separated from the lower casting flask containing the mold and the casting material. is there.
[0006]
[Means for Solving the Problems]
In order to achieve the above objects, the method of removing a casting material from a mold with a casting flask in the present invention is to remove various casting materials having different shapes from the casting mold with upper and lower flasks after a plurality of pouring, respectively. In a method that allows each of the various casting materials to be taken out from the lower casting frame by a single device after the upper casting frame of the mold is lifted and separated from the lower casting frame of the casting mold and the casting material. If the casting material is a general one, the casting material is dropped from the lower casting frame by turning the lower casting frame of the mold and the casting material built-in about 180 degrees by rotating in a vertical plane. After the separation, the lower casting frame in the mold is returned to the original position, and when the casting material is a special one, the casting material is lifted and separated from the lower casting frame by a dedicated casting material lifting means. And it said that there was Unishi.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of an apparatus for removing a casting material from a mold with a casting frame to which the present invention is applied will be described in detail with reference to FIGS. As shown in FIG. 1, the apparatus comprises a reversing means 3 for reversing about 180 degrees by rotating a lower casting frame 2 in a mold 1 in a vertical plane. A casting material lifting means 5 which is provided so as to be capable of entering and exiting via a frame 8 and which lifts the casting material 4 from the inside of the lower casting frame 2; And a casting material holding means 6 for holding the casting material 4 in the casting frame 2 with the casting mold 1 in the lower casting frame 2 and inverting the casting material 4 together with the reversing means 3.
[0008]
As shown in FIG. 1, a shakeout machine 8 for removing a mold piece adhered to the casting material 4 is provided at a left position of the casting material holding means 6, and a casting material 4 is provided at a left position of the shakeout machine 8. Conveyors 9 for transporting the same are provided. Further, a casting material removing means 7 for removing the casting material 4 separated from the inside of the lower casting frame 2 to the outside of the lower casting frame 2 is moved above the reversing means 3 via the portal frame 8. It is arranged as possible.
[0009]
Next, the operation of the thus configured device will be described. In taking out various casting materials having different shapes from the casting molds with upper and lower casting frames after a plurality of pouring, respectively, when the casting material 4 is a general casting material, the upper casting frame inside the casting mold is raised and the casting mold is raised. After being separated from the lower casting frame 2 containing the casting material 1 and the casting material 4 (see FIG. 2A), various casting materials 4 are respectively taken out from the lower casting frame 2 by the present apparatus. The arm is rotated in the clockwise direction to clamp the casting material 4 between the casting mold 1 and the arm in the lower casting flask 2 (see FIG. 2B). The casting material 4 is rotated about 180 degrees by rotating the casting material 4 together with the lower casting frame 2 in the counterclockwise direction of the clock, and the casting material 4 is dropped and separated from the lower casting frame 2 onto the arm of the casting material holding means 6 (FIG. 2 c).
[0010]
Next, the lower casting frame contained in the casting mold 1 is returned to the original position (see FIG. 2D). Subsequently, the casting material 4 separated by the casting material removing means 7 is moved to the left, and (See FIG. 2E). Next, the casting material 4 is further moved to the left and put into the shake-out machine 8 (see FIG. 2) to shake off the mold pieces adhered to the casting material 4, and then cast by appropriate conventional means (not shown). The material 4 is extruded onto the hanger conveyor 9.
[0011]
When the casting material 4 is a special one, the upper casting frame in the mold is raised to separate it from the lower casting frame 2 in the casting mold 4 as in the case of a general casting material 4. (See FIG. 3A). Next, the casting material clamping mechanism of the casting material lifting means 5 is lowered to clamp the casting material 4 (see (b) and (c) in FIG. 3), and then the casting material 4 is lifted and separated from the lower casting frame 2 (FIG. 3)).
[0012]
Next, the lifted casting material is put into the shake-out machine 8 via the casting material lifting means 5, and the lower casting frame 2 is rotated by the reversing means 3 in the counterclockwise direction of the clock to remove the mold in the lower casting frame 2. Then, the mold pieces adhered to the casting material 4 are shaken off by the shake-out machine 8 and the reversing means 3 is returned to the original position (see FIG. 3G).
Next, the casting material 4 is extruded onto the hanger conveyor 9 and the casting material lifting means 5 is moved to a position directly above the lower casting flask 2 (see FIG. 3H).

【effect】
As is apparent from the above description, the present invention is to remove various casting materials having different shapes from the upper and lower casting flasks after pouring a plurality of castings, respectively, by raising the upper casting flask of the mold built-in. A method that allows each of the various casting materials to be taken out from the lower casting frame by a single device after being separated from the lower casting frame containing a mold and a casting material, wherein the casting material is a general one. In such a case, the lower casting frame of the mold and the casting material is turned around in a vertical plane so that the casting material is dropped and separated from the lower casting frame by about 180 degrees, and the casting material is special. In the case, since the casting material is lifted and separated from the inside of the lower casting frame by a dedicated casting material lifting means, various casting materials having different shapes from upper and lower casting frames with a plurality of molten metal after pouring. The In removing each, the upper casting flask with the built-in mold is raised and separated from the lower casting flask with the built-in mold and casting material, and then the various casting materials are respectively removed from the lower casting frame by a single device. It has excellent practical effects such as being able to perform.
