Description

Technical Field

[0001] The invention relates to the technical field of casting and molding, in particular to a pouring device for cylinder sleeve casting production. Background Art

[0002] Casting is an ancient manufacturing method. With the development of industrial technology, the quality of large castings directly affects the quality of products. Therefore, casting occupies an important position in the machinery manufacturing industry. The current casting process generally includes molding, pouring, cooling and sand dropping. The role of molding sand in casting production is extremely important. Ordinary molding sand is mainly composed of raw sand, binder, water and coal powder, etc. It often cannot meet the above-mentioned requirements for molding sand. The casting waste caused by the poor quality of molding sand accounts for about 30-50% of the total casting waste. The hardness of the finished casting is not enough. Not only are there more casting processes, which affects the production capacity, but also The precision of the casting cannot be effectively guaranteed, and the scrap rate is high. The engine is a commonly used mechanical component. At present, with the increasing scarcity of energy and raw materials, the demand for engines is developing towards high power and small size. The cylinder is the core part of the engine. It is the space for gas compression, combustion and expansion, and the trajectory for piston movement. Therefore, the mechanical properties of the cylinder liner are very high, and its quality directly affects the performance and life of the whole machine. The traditional cylinder liner casting method has unstable casting quality. The bubbles in the molten metal cannot be discharged well during pouring, which affects the quality of the subsequent molded cylinder liner. Therefore, it is urgently needed to be improved.

[0095] Reference Figures 1 to 9 , an intermediate mechanism, arranged on the annular plate 5, for conveying molten metal into the casting tank 4;

[0096] The intermediary institutions include:

[0097] There are multiple support columns 8, and the multiple support columns 8 are evenly arranged on the annular plate 5, and the support columns 8 are fixedly connected to the annular plate 5;

At the same time, the distance between the annular cone plate 13 and the arc-shaped cone 14 gradually increases from the direction close to the mold base 1 to the direction close to the liquid inlet hopper 11. Such an arrangement makes the amount of molten metal liquid in the tundish 10 close to the mold base 1 gradually increase from bottom to top, which is beneficial for the subsequent knocking mechanism to discharge the bubbles in the molten metal liquid in the tundish 10, thereby improving the quality of the subsequent formed cylinder liner to a certain extent.

[0130] Working principle: Refer to Figures 1 to 9 When in use, the control device 2 controls the first motor 28 to start, so that the first screw 29 fixedly connected to the output end of the first motor 28 rotates, and the threaded transmission between the first screw 29 and the vertical block 30 makes the connecting block 31 fixedly connected to the vertical block 30 move, so that the pouring part arranged on the connecting block 31 moves, thereby driving the storage part arranged on the pouring part to move, until the ladle 38 in the storage part moves to the pouring position of the adjacent casting slot 4;

[0132] The poured molten metal liquid then enters the tundish 10 through the liquid inlet hopper 11, and the molten metal liquid in the tundish 10 enters the casting tank 4 through the liquid delivery pipe 12. After the molten metal liquid in the casting tank 4 is cooled and formed, the hydraulic push rod 39 is started by the control device 2, so that the hydraulic push rod 39 is extended, and then the push column 40 fixedly connected to the hydraulic push rod 39 is moved toward the direction of the annular plate 5, so that the annular plate 5 is pushed away from the surface of the mold base 1, and then the core 6 fixedly connected to the annular plate 5 is moved out of the casting tank 4, so that the subsequent staff can move the cylinder sleeve formed in the casting tank 4 out of the casting tank 4;

[0133] It should be noted that after the molten metal in the liquid inlet hopper 11 enters the tundish 10, the control device 2 controls the drive motor 15 to start, so that the drive shaft 16 fixedly connected to the output end of the drive motor 15 rotates, and then the driving gear 17 fixedly connected to the drive shaft 16 rotates, and the engagement between the driving gear 17 and the driven gear 19 causes the driven gear 19 to rotate, and then the arc-shaped protrusion 23 fixedly connected to the driven gear 19 rotates around the axis of the driven gear 19, and then the multiple arc-shaped protrusions 23 squeeze the multiple knocking columns 25 in turn, so that the knocking columns 25 move toward the direction of the tundish 10, thereby realizing repeated knocking of the tundish 10, and then discharging the bubbles in the molten metal in the tundish 10, thereby preventing the molten metal containing bubbles from entering the casting tank 4, thereby affecting the quality of the subsequently formed cylinder liner.
