Description
Technical Field
The utility model relates to an investment casting technical field, in particular to the gating system of complicated thin wall foundry goods.
Background
The investment casting is also called lost wax casting, and comprises the procedures of wax pressing, wax trimming, tree forming, slurry dipping, wax melting, molten metal casting, post-treatment and the like. The carbon steel part of the existing stop valve for the precision casting product has the advantages that the inner cavity is circular, the uneven appearance is complex, the wall thickness is thin, the hot junctions are dispersed, a dead head is placed at the hot junctions at the seat ring, feeding cannot be sequentially solidified, the product leaks during pressure testing, for solving the problem of shrinkage porosity of the machined seat ring, the dead head is placed at the side edge to sequentially solidify the dead head, so that the problem of shrinkage porosity of the seat ring is solved, the defect is that the casting process yield is extremely low, and the production cost is improved. Therefore, there is a need to design a better gating system to solve the above problems.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a main aim at provides a gating system of complicated thin wall foundry goods, goes out the combination of air shell through runner stick and toper and forms the blind riser that has the exhaust hole and be connected with the runner of foundry goods shell, is convenient for realize that the order solidifies, prevents the pouring shrinkage porosity, has solved the seat circle shrinkage porosity, and the processing pressure testing seepage has improved the technology product yield, can effectively solve the problem in the background art.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a gating system of complicated thin wall foundry goods, includes foundry goods shell and waters the shell, it communicates through the cross gate with the foundry goods shell to water the shell, water the pouring cup to water the upper end connection of shell, the runner stick is connected to the side of foundry goods shell, the port department of runner stick is equipped with the toper and goes out the gas shell, the runner stick goes out the gas shell combination with the toper and forms the blind riser.
Preferably, the gate pin has a semicircular structure.
Preferably, the gate bar is sized to match the gate dimension of the casting shell.
Preferably, the gate pin is mounted at a hot node of the casting shell.
Preferably, the conical air outlet shell is embedded and installed at the port of the gate stick.

Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
As shown in fig. 1, a pouring system for a complex thin-wall casting comprises a casting shell 1 and a pouring shell 2, wherein the pouring shell 2 is communicated with the casting shell 1 through a horizontal runner 3, the upper end of the pouring shell 2 is connected with a sprue cup 4, the side edge of the casting shell 1 is connected with a sprue bar 5, a tapered gas outlet shell 6 is arranged at the port of the sprue bar 5, the sprue bar 5 and the tapered gas outlet shell 6 are combined to form a blind riser, the tapered gas outlet shell 6 and the sprue bar 5 are separately prepared in a mold, the sprue bar 5 is directly welded on a sprue of a casting wax mold during wax mold welding and is perfectly combined with the wax mold, the blind riser formed by the sprue bar 5 and the tapered gas outlet shell 6 during pouring can be sequentially solidified to solve shrinkage porosity, and the blind riser and the open riser are removed together at the later stage.
In this embodiment, the gate pin 5 has a semicircular structure.
In this embodiment, the size of the gate bar 5 is matched with the size of the gate of the casting shell 1.
In this embodiment the gate pin 5 is mounted at a hot node of the casting shell 1.
In this embodiment, the conical outlet housing 6 is embedded in the port of the gate stick 5.
In this embodiment, the tapered end of the tapered air outlet shell 6 is provided with an air outlet hole.
While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
