Abstract
The utility model discloses a kind of rotor sand mold of improvement, relate to casting field, solve in prior art rotor sand mold process, molten iron produces plug hole and washes away, cause technical problem foundry goods producing fine sand hole, the rotor sand mold that the utility model provides, is provided with the die cavity corresponding with rotor in sand mold, sand mold is provided with plug hole, and plug hole is provided with gate spool.The utility model is applied to the casting of rotor.
Description
[technical field]
The utility model relates to casting field.
[background technology]
By manufacturing the die cavity corresponding with foundry goods profile on sand mold, molten iron injects die cavity by plug hole and is processed to form foundry goods, but in cast injection process, molten iron produces plug hole and washes away, wash away the impurity brought to enter die cavity and cause in foundry goods, producing fine sand hole, affect the quality of finished product.
[summary of the invention]
The technical problem that the utility model solves is to provide a kind of rotor sand mold of improvement, improves the quality of processing.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A rotor sand mold for improvement, is provided with the die cavity corresponding with rotor in described sand mold, and 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 and be arranged on cross gate on described sand mold outer wall and some ingates being communicated with cross gate and die cavity, described cross gate arranges described gate spool.
The beneficial effects of the utility model:
The utility model is provided with gate spool in plug hole, and gate spool separates the inwall of molten iron and plug hole, prevents the sidewall of molten iron to plug hole from washing away and causing impurity to enter die cavity with molten iron, can improve the quality of foundry goods.
These features of the present utility model and advantage will detailed description of the invention below, exposure detailed in accompanying drawing.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model.
[detailed description of the invention]
The technical scheme of accompanying drawing to the utility model embodiment below in conjunction with the utility model embodiment is explained and illustrated, but following embodiment is only preferred embodiment of the present utility model, and not all.Based on the embodiment in embodiment, those skilled in the art under the prerequisite not making creative work obtain other embodiment, all belong to protection domain of the present utility model.
With reference to figure 1, the rotor sand mold of shown a kind of improvement, be provided with the die cavity corresponding with rotor casting 2 shape in sand mold 1, 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 and washes away plug hole 3 generation.
Preferably, gate spool 4 is earthenware.Ceramic material has superpower hardness and wearability, not easily by erosion, and the excellent heat resistance of pottery, the high temperature of molten iron can be born.
Plug hole 3 of the present utility model can be the running channel that drenches with rain, and the running channel that drenches with rain comprises and is arranged on cross gate 31 on sand mold 1 outer wall and some ingates 32 being communicated with cross gate 31 and die cavity, cross gate 31 is arranged gate spool 4.Traditional is cast for order cast gate, foundry goods corner thermal center place easily produces the defects such as shrinkage cavity shrinkage porosity, molten iron of the present utility model is entered ingate 32 by the earthenware 4 on cross gate 31 thus is entered die cavity and forms foundry goods 2, so not only reduce the impurity that molten iron mechanical erosion running channel brings, ensure molten steel quality, thermal center phenomenon can also be avoided.
By above-described embodiment, the purpose of this utility model is reached by fully effective.The personage being familiar with this technology should be understood that the content that the utility model includes but not limited to accompanying drawing and describes in detailed description of the invention above.Any amendment not departing from function and structure principle of the present utility model all will comprise within the scope of the appended claims.
Claims (1)
1. the rotor sand mold improved, the die cavity corresponding with rotor is provided with in described sand mold, described sand mold is provided with plug hole, it is characterized in that: described plug hole is provided with gate spool, described gate spool is earthenware, described plug hole is the running channel that drenches with rain, described in the running channel that drenches with rain comprise and be arranged on cross gate on described sand mold outer wall and some ingates being communicated with cross gate and die cavity, described cross gate arranges described gate spool.
