Drawings
The utility model is further described below with reference to the accompanying drawings.
FIG. 1 is a schematic view of a countergravity sand casting mold;
FIG. 2 is a schematic view of the antigravity sand casting mold after the mold filling is complete;
the casting mold comprises a lower shell sand mold 21, an upper shell sand mold 22, an upper shell sand mold 3, a sprue 4, a cross runner 41, an inclined surface 5, a riser cavity 6, a casting cavity 7, a sand core 8 and a casting mold.
Detailed Description
The utility model will now be further described with reference to the accompanying drawings. These drawings are simplified schematic diagrams only illustrating the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
As shown in fig. 1, the antigravity sand casting mold comprises a sand mold, wherein a casting cavity 6, a riser cavity 5, a cross gate 4 and a sprue 3 are arranged in the sand mold; the sprue 3 is vertically arranged in the sand mold, the lower end port of the sprue 3 is a pouring gate, the upper end of the sprue 3 is communicated with the cross runner 4, the other end of the cross runner 4 is communicated with the upper end of a riser cavity 5, and the lower end of the riser cavity 5 is communicated with a casting cavity 6; the riser cavity 5 is lower than the cross gate 4, and the casting cavity 6 is lower than the upper port of the riser cavity 5 of the casting cavity 6.
Specifically, as an optional embodiment in this embodiment, the bottom surface of the runner 4 is an inclined surface 41, and the lower end of the inclined surface 41 is located on the side of the runner 4. The molten metal in the cross runner 4 can be completely flowed into the sprue 3 under the action of gravity by means of the inclined slope.
Specifically, as an optional implementation manner in this embodiment, a sand core 7 is arranged in the casting cavity 6.
Specifically, as an optional implementation manner in this embodiment, the sand mold includes a lower shell sand mold 21 and an upper shell sand mold 22; the lower shell sand mold 21 and the upper shell sand mold 22 respectively account for half of the casting cavity 6; the cross runners 4 are all positioned in the upper shell sand mould 22.
In this embodiment, the mold cavity 6, the feeder cavity 5, the runner 4, and the sprue 3 are provided in pairs.
The casting process of the die comprises the following steps: molten metal enters the sprue from a sprue gate at the lower end of the sprue 3, then enters the side cross runners 4, then respectively enters the riser cavities 5, and finally fills the casting cavities 6 or the casting molds 8.
As shown in fig. 2, after the mold filling is completed, through pressure release, the molten metal in the sprue 3 and the runner 4 flows back under the action of gravity for secondary use, so that the molten metal is only left in the mold cavity 6 and the riser cavity 5, and the molten metal in the riser cavity 5 independently supplements the mold in the mold cavity 6; because the antigravity casting needs to establish the pressure difference, the mold filling speed is controllable, the process stability is better, and compared with the traditional casting, the molten metal utilization rate of the sprue 3 and the cross runner 4 is saved, so that the maximum utilization rate of the molten metal is reached, the production cost is reduced, and the production efficiency is improved.
Meanwhile, the application range is wide, cast steel, cast iron and colored casting can be general, especially, the application under the high-temperature condition of heat-resistant cast steel sand casting effectively solves the problem of recycling antigravity materials.
In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations can be made by the worker in the light of the above teachings without departing from the spirit of the utility model. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
