[0002] The existing middle tank is also integrally cast, but most of them are sand casting. The casting system of sand casting is completely different from that of lost foam casting. In addition, the middle tank in the original integral casting does not include the vertical plate and the rack seat. Due to its complex structure, the internal impurities are not easy to discharge, so it is cast separately and then welded with the middle tank. This method has low casting efficiency and a long production cycle. Summary of the invention

[0003] It is necessary to propose an integrally cast middle slot vertical casting mold.

[0004] The invention discloses an integrally cast middle groove vertical casting mold, comprising a middle groove white mold and a casting system white mold. The middle groove white mold comprises a shovel plate groove side white mold, a baffle plate groove side white mold, a middle plate white mold, a bottom plate white mold, a rack seat white mold and a vertical plate white mold. The casting system white mold comprises a straight runner white mold and a plurality of side ingates. The straight runner white mold is vertically arranged, and the plurality of side ingates are arranged on both sides of the straight runner white mold. One end of the side ingates is connected to the straight runner white mold, and the other end is connected to the baffle plate groove side wall or the shovel plate groove side wall. The other end of the side ingates is connected to the upper edge of the baffle plate groove side wall or the shovel plate groove side wall. The plurality of side ingates are symmetrically arranged on both sides of the straight runner white mold.

[0005] Preferably, the ingates on both sides include a single ingate white mold, a second ingate white mold, and a third ingate white mold, which are arranged in sequence from bottom to top, and the vertical height difference between the two ingate white molds and the three ingate white molds is greater than the vertical height difference between the single ingate white mold and the two ingate white molds.

DETAILED DESCRIPTION

[0016] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly introduces the drawings required for use in the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0017] See also Figure 1-6 The embodiment of the present invention provides an integrally cast middle groove vertical casting mold, including a middle groove white mold and a casting system white mold, the middle groove white mold includes a shovel plate groove side white mold 11, a baffle plate groove side white mold 12, a middle plate white mold 13, a bottom plate white mold 14, a rack seat white mold 15, and a vertical plate white mold 16, the casting system white mold includes a straight runner white mold 21 and a plurality of side ingates, the straight runner white mold 21 is vertically arranged, and the plurality of side ingates are arranged on both sides of the straight runner white mold 21, and one end of the side ingates is connected to the straight runner white mold 21, and the other end is connected to the baffle plate groove side wall or the shovel plate groove side wall, and the other end of the side ingates is connected to the upper edge of the baffle plate groove side wall or the upper edge of the shovel plate groove side wall, and the plurality of side ingates are symmetrically arranged on both sides of the straight runner white mold 21.

[0018] Since the integral middle groove of the casting of the present invention includes a vertical plate and a rack seat, the capacity of the molten metal on the side of the shovel plate groove during casting is more different from that on the side of the baffle plate groove, so that the liquid level of the molten metal entering along the left inner runner white mold 22 is higher than the liquid level of the molten metal entering from the right inner runner white mold 23, thereby forming a static internal circulation in which the molten metal flows slowly from one side of the baffle plate groove to the other side. The internal circulating liquid flow of the molten metal first forms a vortex flushing on the interior of the complex structure of the mold shell in the baffle plate groove and the shovel plate groove, which is beneficial to draw residual bubbles or moisture on the inner surface of the mold shell into the molten metal, and then float upward and be taken out to avoid staying inside the casting. Secondly, the effect It is even more important for the middle plate, because after the white mold is burned out to form the mold shell, there may be residual lost mold slag on the inner surface of the mold shell, or the mold shell is not dried thoroughly, and there is residual moisture. If these are not discharged, they will remain on the surface gradually, forming shrinkage or pores, pinhole defects, which have a very serious impact on the life of the middle plate. Therefore, the casting molds of the rack seat white mold 15 and the vertical plate white mold 16 are added to further widen the capacity gap between the baffle plate groove and the shovel plate groove, which is helpful to form an internal circulation inside the mold shell, especially in the process of the molten metal passing through the middle plate from the shovel plate groove to the baffle plate groove, a vortex is formed on the inner surface of the middle plate mold shell, and the remaining bubbles, slag, and moisture on the surface of the middle plate mold shell are drawn into the molten metal, and then floated up and taken out.

[0019] The present invention adopts the lost foam casting technology, and the middle groove white mold is an integral component, including the rack seat white mold 15 and the vertical plate white mold 16, the structure is more complex, and it is cast in an integrated manner. In the prior art, sand core casting is used to form an integral middle groove, and the integral middle groove does not include the rack seat and the vertical plate. These two components are still cast separately and are formed by welding the baffle groove side of the middle groove.

[0020] Furthermore, the ingates on both sides include a first ingate white mold 24, a second ingate white mold 25, and a third ingate white mold 26 which are arranged in sequence from bottom to top, and the vertical height difference between the second ingate white mold 25 and the third ingate white mold 26 is greater than the vertical height difference between the first ingate white mold 24 and the second ingate white mold 25.

[0021] Since the bottom pouring method is adopted, the slag inside the shell floats up from the bottom. When the molten metal floats to the second ingrate white mold 25, the inside of the shell has been poured more than half, and there is more slag. At this time, there is more slag on the surface of the molten metal. In order to speed up the rapid floating and discharge of the slag, the vertical height difference between the second ingrate white mold 25 and the third ingrate white mold 26 is shortened, the floating height of the molten metal is shortened, the drop is reduced, and the slag is quickly floated and discharged.

[0022] Furthermore, the ingates on both sides are respectively a left ingate white mold 22 and a right ingate white mold 23. The left ingate white mold 22 is connected between the baffle plate groove side white mold 12 and the straight runner white mold 21. The right ingate white mold 23 is connected between the shovel plate groove side white mold 11 and the straight runner white mold 21. The length of the left ingate white mold 22 is greater than that of the right ingate white mold 23.

[0023] In order to increase the power of the internal circulation flow of the molten metal from the shovel plate groove to the baffle plate groove, the length of the left ingrown white mold 22 is set to be greater than the length of the right ingrown white mold 23, thereby lengthening the path from the straight runner into the baffle plate groove, and the molten metal entering the shovel plate groove flows through the middle plate bottom plate to the baffle plate groove, thereby accelerating the internal circulation.

[0024] Furthermore, the right inner runner white mold 23 is a downwardly inclined inclined runner, thereby further accelerating the speed at which the molten metal flows toward the shovel plate groove and accelerating the internal circulation.

[0025] It should be noted here that both solutions are designed to increase the internal circulation, but the illustrations are only for illustrating the technical effects, so the proportions are not the actual proportions. For example, the length difference between the left ingrow white mold 22 and the right ingrow white mold 23 can be adjusted according to the process, for example, between 5mm-10cm, and adapted due to the different volumes of the middle groove. Similarly, the downward tilt angle of the right ingrow white mold 23 also varies from 1° to 5°.

[0026] Furthermore, the casting system white mold also includes a plurality of slag collection bag white molds 31, which are respectively arranged on the convex end of the baffle plate groove, the convex end of the shovel plate groove, and the end surface of the vertical plate side wall.

[0027] Furthermore, the slag collecting package white mold 31 arranged on the vertical plate white mold 16 is inclined upward.

[0028] During casting, the molten metal floats the slag and impurities upwards and collects them at the highest point of the slag collecting mold 31. The slag collecting mold 31 is arranged obliquely upwards. When the slag enters the slag collecting mold 31, it moves upwards to the highest point. Since the slag has a lighter specific gravity, it will not flow back downwards to the vertical plate. The slag collecting effect is better than the slag collecting mold 31 in the basic solution.

[0029] The modules or units in the device of the embodiment of the present invention may be combined, divided or deleted according to actual needs.

[0030] What is disclosed above is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
