Description

Filter disc bracket for casting

Technical Field

The utility model belongs to the technical field of the casting molten metal filters, concretely relates to kinds of cassette holder.

Background

The filter plate can filter impurities in molten metal and adjust the flow state of the molten metal in casting production, so that the surface of a cast product is smooth, the impurities in the cast product are less, the mechanical property is excellent, the rejection rate is low, the loss of machining tools is reduced, the production cost and energy consumption are reduced, the labor productivity is improved, along with the continuous improvement of the quality requirement of the cast product, a higher requirement is provided for the purity of the molten metal poured into a cavity, therefore, the foamed ceramic filter plate (also called a foamed ceramic filter screen) is applied to .

Disclosure of Invention

The utility model aims to solve the technical problem that an kinds of casting are used filter plate bracket is provided, solve the easy broken problem of foamed ceramic filter plate when the metal liquid measure of pouring is big, improve the filter capacity of foamed ceramic filter plate by a wide margin.

In order to solve the technical problem, the utility model is realized by the following technical proposal that the kinds of filter disc brackets for casting comprise an outer frame and a cavity enclosed by the outer frame, the outer frame extends a plurality of supporting ribs towards the cavity, and the upper end surfaces of the supporting ribs are flush with the upper end surface of the outer frame.

, the support ribs are independent of each other.

, connecting multiple supporting ribs into integral bodies to divide the cavity into multiple cavities.

, at least two of the plurality of support bars are connected and at least support bars are not connected with other support bars.

And , four supporting ribs are distributed in a cross shape.

And , forming round corners at the joints of the support ribs and the outer frame.

, the bracket is made of refractory material.

And , the wall thickness of the outer frame and the support rib is not less than 6 mm.

And , making the outer frame square, and making the side length of the outer frame not less than 100 mm.

And , the height of the outer frame is not less than 8 mm.

The utility model discloses an useful part lies in, and the up end of frame and brace rod plays the effect of supporting the foamed ceramic filter jointly, has solved in the past jumbo size foamed ceramic filter when not having the brace rod to support, at the easy broken problem of pouring metal liquid in-process foamed ceramic filter to improve the filter capacity of foamed ceramic filter by a wide margin.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments:

the embodiment structure is as shown in fig. 1 and fig. 2, kinds of filter plate bracket for casting, the bracket includes frame 1 and the cavity of being enclosed by the frame, frame 1 stretches out a plurality of brace rods 2 to the cavity, 2 up end of brace rod flush with 1 up end of frame, the up end of frame 1 and brace rod 2 plays the effect of supporting the foamed ceramic filter plate jointly, solved in the past jumbo size foamed ceramic filter plate when not having the brace rod to support, at the easy broken problem of pouring metal liquid in-process foamed ceramic filter plate, thereby improve the filter capacity of foamed ceramic filter plate by a wide margin.

In the embodiment, the outer frame 1 is square, the four support ribs 2 are distributed in a cross shape, the four support ribs 2 are connected into whole bodies to divide the cavity into a plurality of cavities, and after the support ribs 2 are connected into a whole body, the strength of the support ribs 2 is better, the contact area with the filter sheet is larger, and the support effect on the filter sheet is better.

The second structure of the embodiment of the present invention is shown in fig. 3, the supporting rib 2 has four pieces, which is cross-shaped, but the supporting rib 2 is independent from each other, and the others are the same as the embodiment . when the supporting rib 2 is connected to be a whole, after contacting with the high temperature metal liquid, the stress of the joint of the supporting rib 2 and the outer frame 1 is larger, the supporting rib 2 is easy to break, and when the supporting rib 2 is independent from each other, the stress of the joint of the supporting rib 2 and the outer frame 1 can be greatly reduced, and the supporting rib 2 is not easy to break.

The three structures of the embodiment of the utility model are as shown in fig. 4, the brace 2 has four equally, be the cross distribution, nevertheless links to each other to brace 2 wherein and be whole, two other braces 2 are disconnected with other braces 2, other are the same with embodiment this kind of partial brace 2 links to each other, the disconnected structure of partial brace 2 is between embodiment and embodiment two, the brace 2 that links to each other can provide better supporting effect, independent brace 2 is difficult for the fracture when sharing supporting effect, can be at the supporting effect and prevent to obtain balance between the brace 2 fracture.

In the above embodiment, the fillet is arranged at the joint of the support rib 2 and the outer frame 1, so that the structural strength of the joint is higher, the stress concentration is small after heating, and the joint is less prone to fracture. The bracket is made of refractory materials, and the refractory materials have the advantages of high-temperature strength and good thermal shock resistance. The wall thickness of the outer frame 1 and the support ribs 2 is not less than 6mm, the side length of the outer frame 1 is not less than 100mm, and the height of the outer frame 1 is not less than 8 mm. This structure ensures that the bracket has sufficient strength to support the filter sheet when the molten metal is poured.

In the above embodiments, the outer frame 1 has a square shape, which is merely specific shapes listed for convenience of description, and the shape of the outer frame 1 can be determined according to the shape of the used filter sheet, such as rectangle, circle, ellipse, other polygons, and is not limited to the square shape.

In the above embodiment, four support ribs 2 are distributed in a cross shape, which is only for convenience of comparing the effects of three cases that the support ribs 2 are independent from each other, and are connected as a whole, and are partially connected, and are not partially connected, rather than limiting the number of the support ribs 2 or the distribution form thereof, the support ribs 2 may be two, three, five, or the like, or other distribution forms such as bilateral symmetry distribution, staggered distribution, central symmetry distribution, and the like may be selected according to the specific number.

It is to be emphasized that: the above embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form, and any simple modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
