Abstract
The invention discloses an improved rotor sand mold, relates to the casting field, and solves the technical problem in the prior art that fine sand holes are generated on a casting because molten iron scours a pouring hole in a rotor sand mold processing process. The rotor sand mold is provided by the invention, the sand mold is internally provided with a rotor-corresponding mold cavity, the sand mold is provide with a pouring hole, and the pouring hole is provided with a pouring tube. The improved rotor sand mold is applied to rotor casting.
Description
[technical field]
The present invention relates to casting field.
[background technology]
Die cavity by manufacture on sand mold with foundry goods contour correspondence, molten iron injects die cavity by plug hole and is processed to form foundry goods, but pours into a mould in injection process, and molten iron produces and washes away plug hole, wash away the impurity bringing and enter die cavity and cause producing fine sand hole in foundry goods, affect the quality of finished product.
[summary of the invention]
The technical problem that the present invention solves is to provide a kind of improved rotor sand mold, improves the quality of processing.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
An improved rotor sand mold, is provided with the die cavity corresponding with rotor in described sand mold, described sand mold is provided with plug hole, and described plug hole is provided with gate spool.
Further, described gate spool is earthenware.
Further, described plug hole is the running channel that drenches with rain, described in the running channel that drenches with rain comprise the cross gate that is arranged on described sand mold outer wall and the ingate of some connection cross gates and die cavity, described gate spool is set on described cross gate.
Beneficial effect of the present invention:
The present invention is provided with gate spool in plug hole, and gate spool is separated the inwall of molten iron and plug hole, prevents that molten iron from washing away and causing impurity to enter die cavity with molten iron the sidewall of plug hole, can improve the quality of foundry goods.
These features of the present invention and advantage will be below the specific embodiment, accompanying drawing in detailed exposure.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the present invention is described further:
Fig. 1 is structural representation of the present invention.
[specific embodiment]
Accompanying drawing below in conjunction with the embodiment of the present invention is explained and illustrated the technical scheme of the embodiment of the present invention, but following embodiment is only the preferred embodiments of the present invention, not all.Embodiment based in embodiment, those skilled in the art are other embodiment that obtains under the prerequisite of not making creative work, all belongs to protection scope of the present invention.
With reference to figure 1, shown a kind of improved rotor sand mold, is provided with the die cavity corresponding with rotor casting 2 shapes in sand mold 1, and sand mold 1 is provided with plug hole 3, and is provided with gate spool 4 on plug hole 3.Gate spool 4 plays a protective role, and reduces molten iron plug hole 3 is produced and washed away.
Preferably, gate spool 4 is earthenware.Ceramic material has superpower hardness and wearability, difficult by erosion, and the excellent heat resistance of pottery, can bear the high temperature of molten iron.
Plug hole 3 of the present invention can be the running channel that drenches with rain, and the running channel that drenches with rain comprises the cross gate 31 that is arranged on sand mold 1 outer wall and the ingate 32 of some connection cross gates 31 and die cavity, and gate spool 4 is set on cross gate 31.Traditional order cast gate that is cast for, foundry goods corner thermal center place easily produces the defects such as shrinkage cavity shrinkage porosity, thereby molten iron of the present invention enters ingate 32 by the earthenware 4 on cross gate 31 and enters die cavity and form foundry goods 2, so not only reduce the impurity that molten iron mechanical erosion running channel brings, guarantee molten steel quality, can also avoid thermal center phenomenon.
By above-described embodiment, object of the present invention is by fully effective having reached.The personage who is familiar with this technology should be understood that the content that the present invention includes but be not limited to accompanying drawing and describe in the specific embodiment above.Any modification that does not depart from function and structure principle of the present invention all will be included in the scope of claims.
