Claims (16)

1. The method for casting the top and bottom cavities without casting holes and this formwork is paired with each other, which includes the process for insertion and support for inserting the double-sided pattern plate (5) between the top (2) and bottom (3) casting holes, which have inlets for casting sand and are horizontal and support the double-sided pattern plate (5); the process for setting for setting the top and bottom casting holes by inserting the upper and lower squeezing trajectories into the openings of the top (2) and bottom (3) casting holes without the double-sided pattern plate (5); the process for rotation and movement for rotating the top (2) and bottom (3) casting holes and the double-sided pattern plate (5) in such a way that these parts are perpendicular and moving them so that the inlets of the top (2) and bottom (3) casting holes move upwards; the process for filling for filling the top and bottom casting holes with casting sand through the inlets of the top (2) and bottom (3) casting holes; and the process for squeezing for squeezing the casting sand of the top and bottom casting holes by bringing the upper and lower squeezing trajectories closer together. The rotation process involves rotating the upper (2) and lower (3) mold pairs and the double-sided pattern plate (5) in such a way that these parts are in a horizontal position, and the removal process involves removing the double-sided pattern plate (5), which is placed between the upper (2) and lower (3) mold pairs, after separating the upper (2) and lower (3) mold pairs, which contain the molds, from the double-sided pattern plate (5). While the previous process was in progress, if necessary, a filler was installed between the upper and lower molds. The upper (2) and lower (3) mold pairs, which contain the molds, are then aligned with each other, and the molds are removed from the aligned upper (2) and lower (3) mold pairs. It is notable that the setting process involves determining the positions for the upper and lower molds by inserting the upper and lower compression trajectories into the openings of the upper (2) and lower (3) mold pairs, which do not contain the double-sided pattern plate (5), and the rotation and movement process. For rotating the upper (2) and lower (3) pairs of chests and the double-sided pattern plate (5) in such a way that these parts are in a perpendicular position and moving them in such a way that the entrances of the upper (2) and lower (3) chests move upward to that side, the upper part is operated simultaneously. 2. The method under claim 1, in which the pressing process for pressing the sand of the top and bottom castings by bringing the top and bottom pressing paths closer together, and the rotation process for rotating the top (2) and bottom (3) pairs of molds and the double-sided pattern plate (5) in such a way that these parts are in a horizontal position, shall be performed simultaneously. 3. The method according to claim 1 in which the top (6) and bottom (7) compression plates are provided as the top and bottom compression methods. 4. The method under claim 1 in which the upper and lower segmented-squeeze feet are provided as the upper and lower compression pathways. 5. The procedure under claim 3, which, after completion of the packing process for packing the upper and lower casting cavities with casting sand through the inlets of the upper (2) and lower (3) molds, shall be further comprised of: a) a process to move the upper clamping plate (6) further apart from the lower clamping plate (7) to a predetermined distance; and b) a packing process for packing the upper and lower casting cavities with casting sand through the inlets of the upper (2) and lower (3) molds. 6. The procedure under claim 5, in which a) the process to move the upper clamping plate (6) further away from the lower clamping plate (7) to a predetermined distance, and b) the process to fill the upper and lower casting spaces with additional casting sand through the inlets of the upper (2) and lower (3) molds, are carried out simultaneously. 7. The procedure under claim 4, in which the process for determining the spacing between the top and bottom molds by inserting the top and bottom compression trajectories into the openings of the top (2) and bottom (3) double-faced pattern plates (5), is further included in the setting process to determine the spacing between the double-faced pattern plates (5) and each number of top and bottom compression plates in such a way that each ratio of the post-compression spacing and the pre-compression spacing are equal. 8. The method under claim 4, in which the process for determining the casting spaces of the top and bottom by inserting the top and bottom compression lanes into the openings of the top (2) and bottom (3) double-sided pattern plates (5), further includes the process for forming the casting spaces determined by the double-sided pattern plates (5) and a number of top and bottom compression plates each in such a way that the sand can easily flow into the casting spaces. 9. The method under claim 8, in which the process to form the casting sand into the casting chamber is determined by the form of a double-sided pattern plate (5) and a number of upper and lower segmented compression plates, each in such a way that the casting sand can easily flow into the casting chamber, shall include a process to reduce the friction between the casting sand and the walls of the air tank (27) by spraying a jet of air into the nozzles of the air tank (27) and the difficult areas for the casting sand to flow. 10. The procedure under claim 4, in which the packing process for packing the upper and lower casting cavities with casting sand through the inlets of the upper (2) and lower (3) molds, and the compression process for compressing the casting sand of the upper and lower casting cavities by bringing the upper and lower compression trajectories closer together, includes: a) the first packing process for packing the upper and lower casting cavities as defined by the upper (2) and lower (3) molds, the upper and lower compression trajectories, and the double-sided pattern plate (5) which is perpendicular to the casting sand through the inlets of the upper (2) and lower (3) molds; b) the first compression process for compressing the casting sand of the upper and lower casting cavities by bringing a certain number of upper and lower segmented compression plates of the upper and lower compression trajectories closer together; c) the second packing process for packing the upper and lower casting cavities with additional casting sand through the inlets of the upper (2) and lower (3) molds after the retraction process for the upper and lower segmented compression plates to retraction; and d) the second compression process. For sand compression in casting, the top and bottom sections of the mold are compressed by using segmented pressing plates, where the surfaces are aligned in a plane, to bring them closer together. 11.
