Description

Technical Field

[0001] The utility model relates to a mounting node for a ceramic filter screen and belongs to the technical field of casting. Background Art

[0002] When pouring molten metal into the sand mold shell, a ceramic filter needs to be installed on the runner to filter the molten metal. When the existing ceramic filter is installed with the sand mold shell, both ends of the ceramic filter are directly connected to the wax mold and sandblasted, and the wax liquid is discharged after heating. The ceramic filter is in the runner in the sand mold shell, see the Chinese patent announcement number CN205056950U.

[0003] Although the ceramic filter screen is located in the runner of the sand mold shell and plays a filtering role, there is no limit between the ceramic filter screen and the sand mold shell, which causes the ceramic filter screen to be easily displaced at the runner of the sand mold shell. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a node for installing a ceramic filter screen.

[0005] The utility model is realized through the following technical solutions.

[0006] The utility model provides a ceramic filter installation node, comprising:

[0007] Ceramic filter that can be confined within the shell runner.

[0008] The ceramic filter screen is provided with a card plate at the periphery thereof, wherein the card plates are multiple and spaced apart from each other;

[0009] It also includes a mold shell, which covers the ceramic filter and the outside of the card plate. The mold shell has a spacing part between two spacing card plates. The mold shell has a space inside to present a runner, and the ceramic filter is in the runner inside the mold shell.

[0010] A U-shaped card slot is arranged on the inner side of the card plate.

[0011] The clamping plate is clamped tightly on the outer periphery of the ceramic filter screen through interference fit in the clamping groove.

[0012] There are four card plates.

[0013] A plurality of the clamping plates are evenly distributed at equal angles and clamped on the outer periphery of the ceramic filter screen.

[0014] The beneficial effect of the utility model is that the spacing part of the mold shell is between two spacing clamping plates, so that the ceramic filter net is restricted in the mold shell by the clamping plates, avoiding the ceramic filter net from being easily displaced at the runner in the sand mold shell, thus solving the problem that the ceramic filter net is easily displaced at the runner in the sand mold shell.

[0019] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0020] like Figures 1 to 3 shown.

[0021] A ceramic filter installation section of the present application includes:

[0022] The ceramic filter screen 1 is in the pouring channel and plays a filtering role when in use. A clamping plate 2 is mounted on the outer periphery of the ceramic filter screen 1 . A U-shaped clamping groove 21 is arranged inside the clamping plate 2 . The clamping plate 2 is clamped tightly on the outer periphery of the ceramic filter screen 1 through the clamping groove 21 .

[0023] There are multiple, for example, four, clamping plates 2. Multiple clamping plates 2 are evenly spaced and equiangularly distributed and clamped on the outer periphery of the ceramic filter screen 1. There is a gap between two clamping plates 2.

[0024] The mold shell 3 is also included. Wax molds are connected to both ends of the ceramic filter screen 1 with the clamping plate 2, and then the mold shell 3 is fixedly formed by sandblasting. The mold shell 3 covers the ceramic filter screen 1 and the outside of the clamping plate 2, so that the spacing part 31 of the mold shell 3 is located between the two spacing clamping plates 2. There is space inside the mold shell 3 to present a runner, and the ceramic filter screen 1 is located in the runner inside the mold shell 3.

[0025] When the mold shell 3 is formed, the spacing part 31 of the mold shell 3 is located between the two spacing clamps 2, so that the ceramic filter screen 1 is restricted in the mold shell 3 by the clamps 2, avoiding the ceramic filter screen from being easily displaced at the runner in the sand mold shell, thus solving the problem of the ceramic filter screen being easily displaced at the runner in the sand mold shell.
