Technical Field

[0001] This utility model relates to the field of casting filter technology, specifically a quick-release filter for casting. Background Technology

[0002] Casting filters are an important tool used in the metal casting process. They are installed in the gating system to remove inclusions, slag, and other non-metallic particles from the molten metal, thereby improving the quality of the castings. Filters are usually made of refractory materials that need to have good high-temperature stability to ensure that they are not damaged or dissolved when the high-temperature molten metal flows through them.

[0003] Currently, in order to remove inclusions, slag, and other non-metallic particles from molten metal and improve casting quality, filters are usually installed in the gating of the casting mold to filter impurities. However, existing filters are usually placed directly in the gating or fixed with screws. One of these methods leads to unstable filter use, and the other affects the efficiency of filter installation and removal. Therefore, improvements are needed. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a quick-release filter for casting, including a casting mold 1, a gating channel 3, and an annular groove on the top of the casting mold 1 located outside the gating channel 3; this structure facilitates the insertion of a pressure sleeve 22; a mounting base 27 is fixedly connected to the inner wall of the annular groove of the casting mold 1; an electromagnet 26 is embedded in the top of the mounting base 27, and multiple electromagnets 26 are evenly distributed in a ring around the top of the mounting base 27; this structure allows multiple electromagnets 26 to be installed through the mounting base 27, thereby ensuring the adsorption effect between the electromagnets 26 and the adsorption block 25; the electromagnets 26 and the adsorption block 25 are magnetically adsorbed and connected, and the adsorption block 25 has an annular structure; this structure allows the pressure sleeve 22 to be tightly connected to the casting mold 1 through the adsorption between the electromagnets 26 and the adsorption block 25, thereby ensuring the limiting effect of the pressure sleeve 22 on the high-temperature resistant filter screen 23; a filter assembly 2 is provided inside the gating channel 3, and an annular groove is provided on the gating channel 3;

[0026] The filter assembly 2 includes a high-temperature resistant filter screen 23 inserted into the annular groove of the gating channel 3. A pressure sleeve 22 is provided on the top of the high-temperature resistant filter screen 23. The top of the pressure sleeve 22 has an outward-flaring structure. A centralized guide hood 21 with a funnel-shaped structure is fixedly connected to the inner wall of the pressure sleeve 22. This structure guides the casting material through the centralized guide hood 21, causing the casting material to flow towards the center of the high-temperature resistant filter screen 23 and preventing the casting material from flowing towards the edges of the high-temperature resistant filter screen 23, thus preventing leakage. An adjusting spring 24 is fixedly connected to the top side of the pressure sleeve 22. The adjusting spring 24 is positioned relative to the top side of the pressure sleeve 22. Multiple rings are evenly spaced in a circular pattern. This structure can support the connection between the adsorption block 25 and the electromagnet 26 by adjusting the spring 24. A ceramic sealing ring 28 is fixedly connected to the bottom of the pressure sleeve 22. A groove is opened on the top side of the high-temperature resistant filter screen 23, and one end of the ceramic sealing ring 28 is inserted into the groove of the high-temperature resistant filter screen 23. The outer wall of the ceramic sealing ring 28 is threaded, and the outer groove of the high-temperature resistant filter screen 23 and the ceramic sealing ring 28 can be matched and threadedly connected, thereby ensuring the stability of the connection between the pressure sleeve 22 and the high-temperature resistant filter screen 23. At the same time, the high-temperature resistant filter screen 23 can be removed when the pressure sleeve 22 is removed, which is convenient for disassembly.

[0027] Working principle: When using this quick-release filter for casting, first connect the high-temperature resistant filter screen 23 to the ceramic sealing ring 28 at the bottom of the pressure sleeve 22 via threads. After installing the high-temperature resistant filter screen 23, insert the pressure sleeve 22 into the annular groove on the outside of the gating channel 3. After the pressure sleeve 22 is inserted into place, the electromagnet 26 is activated. Under the magnetic attraction, the electromagnet 26 drives the adjusting spring 24 to extend, so that the adjusting spring 24 pushes the adsorption block 25 to be tightly attracted to the electromagnet 26, thereby ensuring the stability of the installation of the pressure sleeve 22. During the casting process, the casting material passes through the high-temperature resistant filter screen 23 under the guidance of the centralized guide cover 21 and enters the mold core inside the casting mold 1. If it is necessary to disassemble the pressure sleeve 22 and the high-temperature resistant filter screen 23, turn off the electromagnet 26 to separate the electromagnet 26 from the adsorption block 25, and then pull the pressure sleeve 22 out and rotate the high-temperature resistant filter screen 23 at the bottom of the pressure sleeve 22 to remove it.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
