Abstract
The utility model relates to a filter used for a casting, which comprises a body, wherein a concave groove is arranged in the body, a blanking passage is arranged at the bottom of the concave groove, and a feed inlet is arranged at the top of the concave groove. The filter used for the casting is characterized in that a pre-filter screen is arranged on the feed inlet, the filter holes on the pre-filter screen are S-shaped filter holes, a foamed ceramics filter screen is arranged below the pre-filter screen, and a fixed support is arranged below the foamed ceramics filter screen. The filter used for the casting has advantages of being simple in structure, low in manufacturing cost and good in filter effect.
Description
Technical field
The utility model relates to a kind of foundry goods and uses filter.
Background technology
In the casting process, owing to often contain impurity in the metallic solution, these impurity very easily cause the casting pouring failure in casting process, therefore, before cast, need many metallic solutions to filter.For the common filter that adopts of the metal liquid of high temperature is the foam ceramic filter net; But foam ceramic filter net easy quilt under high temperature and impact is watered to be worn, fragmentation, and then produces secondary impurities, thereby reduces the quality of foundry goods; Cause foundry goods to scrap, influence productivity effect.Therefore, need a kind of new technical scheme to solve above-mentioned technical problem.
The utility model content
The purpose of the utility model provides a kind of foundry goods and uses filter, the good filtration effect of this filter, and can prevent situation such as ceramic foam filter generation fragmentation effectively, guarantee the quality of cast.
The technical scheme that the utility model adopts is:
A kind of foundry goods is used filter, comprises body, is provided with Baltimore groove in the said body; The bottom of said Baltimore groove is provided with blanking channel; The top of said recessed capable groove is provided with charging aperture, and said charging aperture is provided with prefiltering net, and the filtering holes of said prefiltering net is the serpentine filtering holes; The below of said prefiltering net is provided with the foam ceramic filter net, and the below of said foam ceramic filter net is provided with hold-down support.
The top edge of said prefiltering net extends outward fixture, and said prefiltering net is fixed on the body through this fixture.
The filtering holes top of said prefiltering net is the turbination structure.
The filtering accuracy of said prefiltering net is less than the filtering accuracy of foam ceramic filter net.
The utility model adopts the serpentine filtering holes, when cast, not only can carry out pre-filtering to metal liquid, and can slow down the direct impact of metal liquid to ceramic foam filter, and ceramic foam filter is played the certain protection effect.
The utility model has the advantages that: simple in structure, cheap for manufacturing cost, good filtration effect.

Fig. 1 is the overall structure sketch map of the utility model.
Wherein: 1, body, 2, Baltimore groove, 3, blanking channel, 4, charging aperture, 5, prefiltering net, 6, the serpentine filtering holes, 7, the foam ceramic filter net, 8, hold-down support, 9, fixture.
The specific embodiment
As shown in Figure 1, a kind of foundry goods is used filter, comprises body 1; In body 1, be provided with Baltimore groove 2, be provided with the blanking channel 3 that is connected with the sprue gate in the bottom of Baltimore groove 2, be provided with charging aperture 4 at the top of recessed capable groove 2; Charging aperture 4 is provided with prefiltering net 5; The filtering holes of this prefiltering net 5 is a serpentine filtering holes 6, below prefiltering net 5, is provided with foam ceramic filter net 7, below foam ceramic filter net 7, is provided with hold-down support 8.
For the ease of dismounting prefiltering net 5; Top edge at prefiltering net 5 extends outward fixture 9; Prefiltering net 5 is fixed on the body 1 through this fixture 9; In order to guarantee that metal liquid promptly flows into serpentine filtering holes 6 smoothly, the filtering holes top of prefiltering net 5 is adopted as the turbination structure.For the filtering holes that prevents prefiltering net 5 is blocked, the filtering accuracy of prefiltering net 5 is less than the filtering accuracy of foam ceramic filter net 7.
