[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] Embodiment

[0025] As Figures 1-5As shown in the figure, a casting machine with a filtering function includes a lower die base 1. The upper surface of the lower die base 1 is movably connected to an upper die base 2. On both sides of the outer surface of the lower die base 1, first pouring pipes 3 are fixedly connected. On both sides of the outer surface of the upper die base 2, second pouring pipes 4 are fixedly connected. Placement grooves 5 are provided inside both the first pouring pipe 3 and the second pouring pipe 4. A pouring cup 6 is clamped inside the placement groove 5. A filter screen 7 is movably connected to the inner bottom wall of the pouring cup 6. Through holes 8 are provided on both the inner bottom wall and the inner side wall of the pouring cup 6.

[0026] During specific use, through the settings of the first pouring pipe 3, the second pouring pipe 4, the placement groove 5, the pouring cup 6, and the filter screen 7, when the lower die base 1 and the upper die base 2 are closed, the two groups of first pouring pipes 3 and second pouring pipes 4 are aligned with each other to form a pouring runner, facilitating the pouring of molten metal into the mold. The second pouring pipe 4 is shorter than the first pouring pipe 3, which is convenient for workers to view the amount of molten metal being poured from the outside and avoids the phenomenon of molten metal overflow during the casting process. The pouring cup 6 is clamped inside the placement groove 5, which is convenient for installation and disassembly and is easy to clean and replace after use. At the same time, both of them have a trumpet-shaped opening structure, which is more stable during use. The filter screen 7 is placed inside the pouring cup 6. During pouring, the molten metal can stay instantaneously, slowing down the torrent, reducing oxidation and slag inclusion, and improving the quality of the casting. It can cause the aluminum slag in the aluminum liquid and the inclusions with a small density mainly composed of alumina slag generated during the pouring process to float and separate from the molten metal. When these inclusions pass through the regular through holes 8 or irregular mesh holes, a deep adsorption effect can also be generated, and it can continuously purify the molten metal before the pouring cup 6 is full, reducing impurities to avoid slag holes and roughness inside the product, resulting in defects.

[0027] In this embodiment, clamping grooves 9 are provided on both sides of the upper surface of the first pouring pipe 3. Sealing strips 10 are fixedly connected to both sides of the lower surface of the second pouring pipe 4.

[0028] During specific use, through the settings of the clamping groove 9 and the sealing strip 10, when the first pouring pipe 3 and the second pouring pipe 4 are aligned, the sealing strip 10 is clamped inside the clamping groove 9, strengthening the sealing performance at the connection of the inner sides of the first pouring pipe 3 and the second pouring pipe 4 and avoiding the phenomenon of liquid leakage.

[0029] In this embodiment, brackets 11 are movably connected to both sides of the front surface of the lower die base 1 through bolts. An oil cylinder 12 is fixedly connected to the middle of the outer surface of the bracket 11.

[0030] During specific use, through the setting of the oil cylinder 12, the bracket 11 is connected to the lower die base 1 through bolts, making it more convenient to disassemble and assemble when the oil cylinder 12 is damaged. The oil cylinder 12 moves forward and backward in a reverse installation, keeping the oil seal of the oil cylinder 12 away from the mold, preventing the oil seal from burning out due to being too close to the mold and causing oil leakage.

[0031] In this embodiment, a connecting plate 13 is fixedly connected to the output end of the oil cylinder 12. On both sides of the inner surface of the connecting plate 13, connecting rods 14 are fixedly connected. One end of the connecting rod 14 is fixedly connected to a slider 15.

[0032] During specific use, through the setting of the slider 15, the slider 15 is slidably connected inside the lower die base 1 and is connected to the connecting rod 14. When the output end of the oil cylinder 12 expands and contracts, the connecting rod 14 is driven to move through the connecting plate 13, thereby causing the slider 15 to move and realizing the core-pulling operation.

[0033] In this embodiment, connecting columns 16 are movably connected to both sides of the lower surface of the lower die base 1 and both sides of the upper surface of the upper die base 2 through bolts. One end of the connecting column 16 is movably connected to a support plate 17 through a bolt.

[0034] During specific use, through the setting of the connecting column 16 and the support plate 17, the connecting column 16 is fixed to the lower surface of the lower die base 1 and the upper surface of the upper die base 2 through bolts, and the support plate 17 is connected to the connecting column 16 through bolts, playing a role in supporting the lower die base 1 and the upper die base 2, and the connection is more convenient and fast.

[0035] In this embodiment, a mounting plate 18 is slidably connected to one side of the outer surface of the connecting column 16. A mounting hole 19 is formed in the lower surface of the mounting plate 18, and a ejector pin 20 is inserted into the inside of the mounting hole 19.

[0036] During specific use, through the setting of the ejector pin 20, multiple ejector pins 20 are inserted into the inside of the mounting plate 18 through the mounting holes 19. Under the action of the ejector pins 20, the demolding function of the mold is realized, and the ejection action of the mold can be made smoother.

[0037] In this embodiment, a limiting plate 21 is movably connected to the lower surface of the mounting plate 18 through a bolt. Positioning grooves 22 are formed on both sides of the outer surfaces of the limiting plate 21 and the mounting plate 18.

[0038] During specific use, through the setting of the limiting plate 21 and the positioning grooves 22, the limiting plate 21 is connected to the mounting plate 18 through a bolt to limit the bottom of the ejector pin 20, making the installation and disassembly of the ejector pin 20 more convenient, facilitating replacement when damaged, without the need to replace the whole, saving costs. The positioning grooves 22 are slidably connected to the connecting column 16, making the movement of the mounting plate 18 and the limiting plate 21 more accurate and stable, preventing deviation during the movement process, and improving the displacement accuracy of the ejector pin 20.

[0039] Working principle: During use, when the lower die base 1 and the upper die base 2 are closed, the two groups of first pouring pipes 3 and second pouring pipes 4 are mutually aligned to form a pouring runner, facilitating the pouring of molten metal into the mold. At the same time, the sealing strip 10 is clamped inside the clamping groove 9 to strengthen the sealing performance at the connection between the inner sides of the first pouring pipe 3 and the second pouring pipe 4, preventing liquid leakage. The pouring cup 6 is clamped inside the placement groove 5, and the filter screen 7 is placed inside the pouring cup 6. During pouring, the molten metal can stay instantaneously, slowing down the turbulent flow, reducing oxidation and slag inclusion, enabling inclusions with low density to float and separate from the molten metal, playing a role in purifying the molten metal to avoid slag holes and roughness inside the product, which may cause defects. When the first pouring pipe 3 and the second pouring pipe 4 are aligned, when the output end of the oil cylinder 12 expands and contracts, it drives the connecting rod 14 to move through the connecting plate 13, causing the slider 15 to move, realizing the core-pulling operation. After pouring and cooling, the upper die base 2 and the lower die base 1 are separated. Under the action of multiple ejector pins 20, the mold is demolded, enabling the ejection action of the mold to be smooth.
