Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of high-chromium cast iron casting, in particular to a casting and molding device for producing high-chromium cast iron. Background Art
[0002] High chromium cast iron is a kind of cast iron containing a large amount of chromium. Its main characteristics are high wear resistance and corrosion resistance. Due to its excellent performance, high chromium cast iron is usually used to manufacture wear-resistant parts, such as mechanical parts with severe wear, mining machinery, water pumps, crusher parts, etc. It is also widely used in mining, cement, building materials and other industries where wear-resistant materials are required. High chromium cast iron can be improved by alloying to improve its wear resistance, and it can also be heat treated according to specific working conditions to further improve its performance.
[0003] If the casting head does not have an anti-blocking function during the casting of high chromium cast iron, some disadvantages will occur. First, it may cause poor flow of molten metal, resulting in reduced filling performance, causing defects such as holes and inclusions inside the casting, affecting the quality and mechanical properties of the casting. Secondly, it may cause reflux or vortex of the molten metal, which will further lead to uneven solidification and unstable organizational structure of the casting, reducing the strength and toughness of the casting. In addition, it is easy to cause unstable casting, reduce the dimensional accuracy of the casting, and increase the difficulty of subsequent processing. Finally, the casting head without an anti-blocking function may increase the loss of molten metal during the casting process, increase production costs and waste of resources.

A movable sleeve 10 is movably connected to the surface of the crankshaft 9. The bottom of the movable sleeve 10 is movably connected to a connecting rod 11 through a rotating shaft. The bottom of the connecting rod 11 is movably connected to a movable plate 12 through a rotating shaft. The left side of the bottom of the movable plate 12 is fixedly connected to a movable rod 13. The right side of the movable plate 12 is fixedly connected to a slider 15. A chute 14 is opened at the bottom of the right side of the inner wall of the storage box 3. The right side of the slider 15 is slidably connected to the inner cavity of the chute 14. A rotating motor 4 is fixedly connected to the top of the storage box 3. The output end of the rotating motor 4 is fixedly connected to a stirring rod 5. Clamps 6 are fixedly connected to the top of the left and right sides of the inner wall of the storage box 3. A filter screen 7 is clamped in the inner cavity of the clamp 6.
[0022] Through the above technical solution, the output end of the servo motor 8 drives the crankshaft 9 to rotate. During the rotation of the crankshaft 9, the movable plate 12 is driven to move up and down by using the principle of the crank mechanism through the movable sleeve 10 and the connecting rod 11. The movable plate 12 drives the movable rod 13 to move up and down in the inner cavity of the feeding pipe 16, avoiding the situation that the inner cavity of the feeding pipe 16 is blocked and causing difficulties in subsequent casting, improving the casting efficiency and accuracy. By setting the chute 14 and the slider 15, the stability of the movable plate 12 during the up and down movement can be effectively improved. By driving the stirring rod 5 to rotate through the output end of the rotating motor 4, the materials in the inner cavity of the storage box 3 can be fully stirred to avoid their adhesion. By setting the filter screen 7, the materials can be filtered, and the solids or impurities doped in the materials can be retained, further avoiding the blockage of the feeding pipe 16.
[0023] Specifically, a feeding pipe 16 is communicated with the bottom of the storage box 3. A pump 17 is fixedly connected to the top of the inner cavity of the casting box 2. The bottom of the feeding pipe 16 is communicated with the input end of the pump 17. The bottom of the movable rod 13 penetrates into the inner cavity of the feeding pipe 16. The output end of the pump 17 is communicated with a corrugated pipe 18. Electric push rods 19 are fixedly connected to the left and right sides of the top of the inner cavity of the casting box 2. The output end of the electric push rod 19 is fixedly connected to an upper template 20. The bottom of the corrugated pipe 18 penetrates through the inner surface of the upper template 20 and extends to the bottom of the upper template 20. A lower mold 21 is fixedly connected to the bottom of the inner cavity of the casting box 2. A cooling box 25 is fixedly connected to the bottom of the inner cavity of the casting box 2 and below the lower mold 21. A refrigerating rod 26 is fixedly connected to the middle end of the inner cavity of the cooling box 25. Flow guiding fans 27 are arranged on the left and right sides of the bottom of the inner cavity of the lower mold 21. A mold cavity 22 is opened at the middle end of the top of the lower mold 21. Electric telescopic rods 23 are fixedly connected to the left and right sides of the inner cavity of the lower mold 21. The output end of the electric telescopic rod 23 is fixedly connected to a blanking plate 24.
[0024] Through the above technical solutions, by providing the card seat 6, the filter screen 7 can be disassembled for cleaning or replacement. By providing the refrigerating rod 26, the inner cavity of the cooling box 25 can be refrigerated and cooled. By providing the diversion fan 27, cold air can be blown upward to cool the lower mold 21, improving the subsequent forming efficiency. By providing the electric telescopic rod 23 and the ejector plate 24, the formed material can be pushed upward, facilitating collection.
[0025] During use, first, the output end of the motor 4 rotates to drive the stirring rod 5 to rotate, fully stirring the material. At the same time, the material is filtered through the filter screen 7 to retain the impurities mixed in the material. During the casting process, the output end of the electric push rod 19 drives the upper template 20 to move downward, so that the bottom of the upper template 20 contacts the top of the lower mold 21. Then, the pump 17 generates suction to suck the material in the inner cavity of the storage tank 3 through the feeding pipe 16. After that, the output end of the pump 17 casts the material into the inner cavity of the mold groove 22 through the corrugated pipe 18 for forming. At the same time, the output end of the servo motor 8 drives the crankshaft 9 to rotate. During the rotation of the crankshaft 9, the movable sleeve 10 and the connecting rod 11 drive the movable plate 12 to move up and down using the principle of the crank mechanism. The movable plate 12 drives the movable rod 13 to move up and down in the inner cavity of the feeding pipe 16, preventing the situation that the inner cavity of the feeding pipe 16 is blocked, causing difficulties in subsequent casting.
[0026] After casting is completed, while the cooling device cools the lower mold 21, the refrigerating rod 26 refrigerates and cools the inner cavity of the cooling box 25. The fan blades of the diversion fan 27 rotate to blow cold air upward to continuously cool the lower mold 21, improving the forming efficiency. After cooling is completed, the output end of the electric telescopic rod 23 extends upward and drives the ejector plate 24 to move upward to push the workpiece out of the inner cavity of the mold groove 22 (the above is the working process of the entire device. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art).
