[0027] The specific implementation methods of the present utility model will be further explained in detail below by describing the optimal embodiments with reference to the accompanying drawings.

[0028] A static pressure line valve body casting pouring system comprises a casting cavity 1, the casting cavity 1 is connected to a runner mechanism; the casting cavity 1 comprises a main pipe cavity 11; a branch pipe cavity 13 and a flange cavity 12 are arranged on the main pipe cavity 11; the branch pipe cavity 13 is arranged on one side of the main pipe cavity 11 close to the runner mechanism; the runner mechanism is connected to the branch pipe cavity 13; the utility model controls the arrangement direction of the branch pipe cavity 13, so that the molten iron that subsequently enters through the runner mechanism can be filled in the casting cavity 1 through the branch pipe cavity 13, thereby avoiding the shrinkage defect that is easy to form at the connection between the branch pipe and the main pipe during traditional pouring.

[0029] The pouring system disclosed in the utility model is mainly used for pouring and molding a DN80-300 valve body. Specifically, the pouring system disclosed in the utility model mainly includes a casting cavity 1; the setting of the casting cavity 1 is mainly used for pouring and molding parts. In addition, in the utility model, the casting cavity 1 is connected with a runner mechanism; the setting of the runner mechanism facilitates the pouring of metal into the casting cavity 1, thereby realizing the molding operation of the valve body.

[0030] In addition, in the utility model, the casting cavity 1 includes a main pipe cavity 11; the main pipe cavity 11 is provided with a branch pipe cavity 13 and a flange cavity 12; the main pipe cavity 11, the branch pipe cavity 13 and the flange cavity 12 disclosed in the utility model are mainly designed based on the shape of the casting, so the number and position are also designed according to the actual shape of the casting.

[0031] In addition, in the present invention, the branch pipe cavity 13 is arranged on the side of the main pipe cavity 11 close to the runner mechanism; the runner mechanism is connected to the branch pipe cavity 13; such an arrangement allows the molten metal or molten iron to first enter the branch pipe cavity 13 and then enter the main pipe cavity 11, thereby avoiding the traditional method of entering iron from the flange and then merging at the branch pipe, because the branch pipe is far away from the inner runner, resulting in cold shut waste after pouring.

[0032] Furthermore, in the utility model, the runner mechanism includes a straight runner 2 and an endogate; the straight runner 2 is connected to the branch pipe cavity 13 and / or the flange cavity 12 through the endogate; during actual pouring, the straight runner 2 is the main runner, and the straight runner 2 is connected to the branch pipe cavity 13 and the flange cavity 12 through the endogate. During the specific connection, the endogate can be connected to the branch pipe cavity 13 alone, or to the flange cavity 12 alone, and of course, it can also be connected to the branch pipe cavity 13 and the flange cavity 12 at the same time; ensuring the filling speed of the casting cavity 1.

[0033] Furthermore, in the utility model, the ingrowth includes a branch ingrowth 5 and a flange ingrowth 4; the straight runner 2 is connected to the branch cavity 13 through the branch ingrowth 5; the straight runner 2 is connected to the flange cavity 12 through the flange ingrowth 4; based on such a setting, the branch ingrowth 5 and the flange ingrowth 4 are set to facilitate the connection between the straight runner 2 and the branch cavity 13 and the flange cavity 12, and subsequently cooperate with the cross runner mechanism 3 to realize the connection between the straight runner 2 and the corresponding ingrowth; it is convenient for the castable to enter the corresponding cavity during subsequent pouring.

[0034] Furthermore, in the utility model, the straight runner 2 is connected to the inner runner through a cross runner mechanism 3; the cross runner mechanism 3 includes a main cross runner 31; the main cross runner 31 is connected to the inner runner through a branch cross runner 32; the main cross runner 31 is a main transition conduit, which facilitates the pouring liquid entering the straight runner 2 to flow in the main cross runner 31, facilitating subsequent diversion operations, and in actual use, the main cross runner 31 is required to be connected to the corresponding cavity through each branch cross runner 32, so as to facilitate the pouring material to enter the corresponding cavity.

[0035] Furthermore, in the utility model, each branch cavity 13 is connected to two branch endogates 5, and the two branch endogates 5 on each branch cavity 13 are relatively symmetrically distributed; such an arrangement enables casting material to be injected on both sides of each branch cavity 13, thereby ensuring the filling speed of the cavity.

[0036] Furthermore, in the present invention, each branch pipe inner runner 5 connected to the branch pipe cavity 13 is connected to the main cross runner 31 through a branch cross runner 32; such an arrangement allows the castable in the same main cross runner 31 to be diverted and injected into the same branch pipe cavity 13 at the same time.

[0037] In actual design, the cross-sectional area of ​​the main runner 31 is larger than that of the branch runner 32 .

[0038] Furthermore, in the utility model, risers are provided on the branch pipe cavity 13 and the flange cavity 12 in the casting cavity 1; the function of the risers is mainly to realize the functions of exhaust and slag collection, and to allow the pipeline casting to solidify sequentially to reduce defects such as shrinkage cavities, shrinkage, and deformation.

[0039] specific:

[0040] The utility model discloses a static pressure line valve body casting pouring system, comprising a casting cavity 1, the casting cavity 1 is connected with a runner mechanism; the casting cavity 1 comprises a main pipe cavity 11; a branch pipe cavity 13 and a flange cavity 12 are arranged on the main pipe cavity 11; the branch pipe cavity 13 is arranged on one side of the main pipe cavity 11 close to the runner mechanism; the runner mechanism is connected with the branch pipe cavity 13; the runner mechanism comprises a straight runner 2 and an ingode; the straight runner 2 is connected with the branch pipe cavity 13 and / or the flange cavity 12 through the ingode. The ingode includes a branch ingode 5 and a flange ingode 4; the straight runner 2 is connected to the branch cavity 13 through the branch ingode 5; the straight runner 2 is connected to the flange cavity 12 through the flange ingode 4; the straight runner 2 is connected to the ingode through a cross runner mechanism 3; the cross runner mechanism 3 includes a main cross runner 31; the main cross runner 31 is connected to the ingode through a branch cross runner 32; each branch cavity 13 is connected to two branch ingodes 5, and the two branch ingodes 5 on each branch cavity 13 are relatively symmetrically distributed.

[0041] Based on the above design, the casting to be poured disclosed in the utility model is fed with iron from the branch pipe, and the orientation of the branch pipe cavity 13 is controlled so that shrinkage compensation can be performed on the casting through the pouring system; at the same time, the utility model requires that the branch pipe cavity 13 be provided with a riser, and the riser is used to strengthen shrinkage compensation; at the same time, each branch pipe cavity 13 is connected to two branch pipe endogates 5, that is, iron is fed on both sides of the branch pipe cavity 13, so that the filling speed is fully guaranteed.

[0042] During molding and pouring, the molten iron flows through the sprue 2, the main runner 31, the branch runner 32 and the corresponding ingates, and finally flows into the casting cavity 1.

[0043] In summary, it should be noted that the casting to be poured in the present invention is a DN80-300 valve body; of course, it can also be other pipe structures.

[0044] The castable can be molten iron or some other molten metal, and the specific choice can be made according to needs.

[0045] The utility model can greatly reduce the inherent defects of the DN80-300 valve body according to the pouring system design, and the iron is fed from the branch pipe so that the iron feeding speed of the branch pipe is fast, the branch pipe is compensated for shrinkage, and the cold shut waste is reduced from 40% to less than 2%, thereby saving production costs.

[0046] Obviously, the specific implementation of the present invention is not limited by the above-mentioned methods.
