Description

Technical Field

[0001] This utility model relates to the field of metal casting manufacturing technology, specifically a metal casting system with anti-oxidation and impurity filtration functions. Background Technology

[0002] During the casting process of metal castings, molten metal is prone to oxidation reaction with oxygen in the air, generating oxide impurities. This not only affects the quality and performance of the castings but may also lead to defects such as porosity and sand holes. Simultaneously, the molten metal itself may carry some impurity particles. If not effectively filtered, these impurities will enter the casting, reducing its strength and precision. Existing casting systems often struggle to simultaneously and effectively address both molten metal oxidation and impurity filtration. Therefore, there is an urgent need for a casting system that can achieve both anti-oxidation and impurity filtration functions to improve the quality and production efficiency of metal castings. Utility Model Content

The casting mold is provided with a casting port. The anti-oxidation filter casting connector includes a filter box. One end of the filter box is connected to a discharge pipe, which is connected to the casting port. A filter plate is provided inside the filter box, and the filter plate is provided with several through holes. The other end of the filter box is connected to a feed pipe. A funnel-shaped connector is provided at the feed inlet of the feed pipe. An outer cover is provided outside the connector. The lower end of the outer cover is sealed to the outer wall of the connector. An air outlet is provided between the upper end of the outer cover and the connector.

[0026] like Figure 1-6As shown, in this embodiment, a metal casting system with anti-oxidation and impurity filtration functions includes a casting mold 1 and an anti-oxidation and filtration casting connector 2. The casting mold 1 is provided with a casting port 11; the anti-oxidation and filtration casting connector 2 includes a filter box 21, one end of which is connected to a discharge pipe 22, which is connected to the casting port 11. A filter plate 23 is provided inside the filter box 21, and the filter plate 23 is provided with several through holes 231. The other end of the filter box 21 is connected to a feed pipe 24, and a funnel-shaped connector 25 is provided at the feed inlet of the feed pipe 24. An outer cover 26 is provided on the outside of the connector 25. The lower end of the outer cover 26 is closed and connected to the outer wall of the connector 25. An air outlet 27 is provided between the upper end of the outer cover 26 and the connector 25. An air inlet 28 is provided on the outer cover 26, and the air inlet 28 is connected to an inert gas supply device 3 through an air pipe. In this embodiment, a sedimentation chamber 30 is provided at the bottom of the filter box below the feed pipe 24.

[0027] Furthermore, the filter plate 23 is made of ceramic. The ceramic filter plate 23 has the characteristics of high temperature resistance and good chemical stability, and can maintain good filtration performance under the flushing of high temperature molten metal, and is not prone to chemical reaction with molten metal.

[0028] Furthermore, the top surface of the casting mold 1 is provided with an air inlet 12, which is connected to the inert gas supply device 3 via an air pipe. By providing the air inlet 12 on the top surface of the casting mold 1, inert gas can be introduced into the casting mold 1, further preventing the molten metal from oxidizing inside the casting mold 1.

[0029] Furthermore, the outer casing 26 has several air inlets 28 evenly distributed on its sidewalls, and each air inlet 28 is connected to the inert gas supply device 3 via an air pipe. The arrangement of multiple air inlets 28 allows the inert gas to fill the interior space of the outer casing 26 more evenly, ensuring the anti-oxidation effect on the molten metal at the feed inlet.

[0030] Furthermore, a horizontal baffle 211 is provided inside the filter box 21 and at one end near the discharge pipe 22, with the discharge pipe 22 located at the lower end of the horizontal baffle 211. The horizontal baffle 211 allows the molten metal filtered by the filter plate 23 to form a certain liquid level in the filter box 21, which buffers and stabilizes the flow rate of the molten metal, allowing the molten metal to flow more smoothly into the casting mold 1.

[0031] Furthermore, a number of connecting arms 29 are provided between the outer cover 26 and the docking device 25. The connecting arms 29 are used to support the outer cover 26, ensuring the relative position between the outer cover 26 and the docking device 25 is stable, while not affecting the flow of inert gas.

[0032] Furthermore, several filter plates 23 are arranged horizontally inside the filter box 21. Several slots 212 are provided on the top of the filter box 21. Below each slot 212, several protrusions 213 are arranged in a straight line and spaced apart on the bottom surface of the filter box 21. Slots 232 are provided on the bottom surface of the filter plates 23, and the corresponding slots 232 engage with the protrusions 213 for connection. The arrangement of multiple filter plates 23 improves the filtration effect, and the connection between the filter plates 23 and the filter box 21 using slots 232 and protrusions 213 facilitates the installation and removal of the filter plates 23, and makes cleaning and replacement of the filter plates 23 convenient.

[0033] Furthermore, the protrusions 213 below two adjacent inlets 212 are staggered. The staggered protrusions 213 allow the installation positions of adjacent filter plates 23 to be offset from each other, preventing molten metal from flowing directly through the gaps between the filter plates 23, thereby further improving the filtration effect.

[0034] The working principle of the above technical solution is as follows:

[0035] In practical use, the inert gas supply device 3 is connected via gas pipes to the air inlet 28 on the outer cover 26 and the air inlet 12 on the top surface of the casting mold 1. Activating the inert gas supply device 3 introduces inert gas, such as argon, into the outer cover 26 outside the docking device 25 and into the casting mold 1, creating an inert gas protective atmosphere at the inlet and inside the casting mold 1.

[0036] The molten metal enters the filter box 21 through the inlet of the feed pipe 24 and the funnel-shaped connector 25. Inside the filter box 21, the molten metal passes sequentially through several horizontally arranged filter plates 23. The through holes 231 on the filter plates 23 filter impurities in the molten metal. Because the protrusions 213 below adjacent inlets 212 are staggered, the installation positions of adjacent filter plates 23 are offset from each other, and the molten metal can only be filtered through the through holes 231 on the filter plates 23, ensuring the effectiveness of impurity filtration.

[0037] After filtration, the molten metal is buffered by the baffle plate 211 in the filter box 21 and flows smoothly from the discharge pipe 22 into the casting port 11 of the casting mold 1 to complete the casting process.

[0038] When it is necessary to clean or replace the filter plate 23, it can be directly removed from the slot 212 at the top of the filter box 21. Since the slot 232 on the bottom of the filter plate 23 engages with the protrusion 213 on the bottom of the filter box 21, the disassembly process is simple and convenient. After cleaning or replacement, the filter plate 23 can be reinstalled into the filter box 21 through the slot 232 and the protrusion 213 for continued use.

[0039] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
