Description
Technical Field
[0001] The present application relates to the technical field of alloy casting, and in particular to a precision casting device for ultra-high chromium casting balls. Background Art
[0002] In the field of casting technology, ultra-high chromium cast balls are widely used in mining, cement, power and other industries due to their excellent wear resistance and corrosion resistance. However, traditional casting processes often face problems such as waste of raw materials and low production efficiency when manufacturing ultra-high chromium cast balls. Therefore, the development of a device that can accurately cast ultra-high chromium cast balls is of great significance to improving the quality and production efficiency of cast balls.
[0003] The existing technology still has the following problems:
[0004] 1. In the casting process of ultra-high chromium casting balls with existing precision casting equipment, the smelted alloy metal liquid is manually poured into the mold. The temperature of the metal liquid is high, and manual casting is easy to scald the workers. In addition, the amount of casting cannot be adjusted according to the size of the ultra-high chromium casting balls during the casting process, resulting in uneven material feeding, which causes the quality of the cast ultra-high chromium casting balls to be low. In addition, the metal liquid is easy to splash when pouring, which causes damage to the equipment and even injures the workers, thus causing safety problems.
[0005] 2. In the process of placing molten metal into the inner cavity of the mold in the existing precision casting equipment, the molten metal is injected from an inlet, and the process of the molten metal flowing into the entire inner cavity of the mold is relatively slow. When the flow speed of the molten metal is too slow, the molten metal that flows in first may have begun to cool and solidify, and the molten metal that flows in later cannot be well integrated with it, thereby forming a cold shut defect on the surface of the casting, reducing the durability of the ultra-high chromium cast ball, thereby reducing the production efficiency and production efficiency of the ultra-high chromium cast ball.

The outer surface of the processing table 1 is fixedly connected to the second fixed block 633, and the inner cavity of the second fixed block 633 is rotatably connected to the gear 634. The outer surface of the second fixed block 633 is fixedly connected to the limiting sleeve 635, and the inner cavity of the second fixed block 633 is slidably connected to the gear rack 636. The upper surface of the gear rack 636 is fixedly installed with a support block 637.

The top of the support block 637 is tightly fitted with the lower surface of the lower mold 3, and at this time there is a gap between the shaking plate 628 and the lower surface of the lower mold 3, which is convenient for exchanging flexible support and rigid support. When the support transformation of the shaking mechanism 62 and the support mechanism 63 is performed, the sliding seat 613 is driven to slide on the fixed seat 612 by rotating the first threaded rod 616, and the sliding of the sliding seat 613 drives the first connecting strip 614 to rotate, and the rotation of the first connecting strip 614 drives the second connecting strip 615 to rotate on the bottom frame 611, and the rotation of the second connecting strip 615 drives the height of the adjusting block 617 to change, and the height change of the adjusting block 617 drives the height of the support plate 618 to change.The support plate 618 rises, driving the height of the smoothing mechanism 62 to rise. At this time, the support plate 618 drives the second connecting plate 631 to rise. The second connecting plate 631 moves up, driving the rack 632 to move up. The rack 632 moves up, driving the gear 634 to rotate in the inner cavity of the second fixed block 633. The rotation of the gear 634 drives the rack 636 to move down in the inner cavity of the rack 636. At this time, the rack 636 drives the support block 637 to move down, so that the support block 637 is out of contact with the ground of the lower mold 3, thereby losing the support effect of the support block 637 on the lower mold 3. At the same time, the support The rise of plate 618 drives the second connecting frame 621 to move upward. At this time, the shaking plate 628 contacts the ground of the lower mold 3. At the same time, the first spring 2 flexibly supports the lower mold 3. During the upward movement of the support plate 618, the button 64 contacts the slider 67, so that the slider 67 presses the button 64, thereby driving the motor 623 to work. The work of the motor 623 drives the motor 623 to rotate. The rotation of the motor 623 drives the connecting sleeve 624 to rotate. The rotation of the connecting sleeve 624 drives the shaking frame 625 to rotate. The long rod of the connecting sleeve 624 is tilted, thereby driving The shaking frame 625 shakes, causing the floating seat 626 and the bent rod 627 to shake as a whole, thereby causing the shaking plate 628 to have a shaking effect. At this time, the shaking plate 628 has a supporting effect on the bottom end of the lower mold 3, and the first spring 2 flexibly supports the lower mold 3, thereby driving the lower mold 3 and the upper mold 4 to shake under the shaking of the shaking plate 628, so that the molten metal quickly enters the inner cavity of the mold, which is convenient for rapid molding of the mold and prevents the molten metal from flowing too slowly and the molten metal that flows in first has begun to cool and solidify, while the molten metal that flows in later cannot It is well integrated with the mold to avoid the formation of cold shut defects on the surface of the casting. Shaking the mold can promote the flow of molten metal in the mold, which helps to reduce internal defects caused by uneven metal solidification, such as cracks, inclusions, etc., and helps to improve production efficiency. After the casting metal liquid is shaken, the first threaded rod 616 is rotated again to make the shaking plate 628 separate from the contact with the lower mold 3. At this time, the support block 637 contacts the lower mold 3 again and supports the lower mold 3, ensuring that it is not easy to deform during the cooling and molding process, thereby ensuring the dimensional accuracy of the casting.
[0044] In summary, when casting ultra-high chromium cast balls, the casting component 5 is used to evenly load the material so that the molten metal enters the inner cavity of the lower mold 3 and the upper mold 4. The molten metal in the inner cavity of the lower mold 3 and the upper mold 4 is shaken by the shaking component 6 so that the molten metal is quickly dispersed to various parts of the inner cavity of the lower mold 3 and the upper mold 4. The first spring 2 is used for flexible support, so that the lower mold 3 can shake on the first spring 2 when the shaking component 6 is shaken. At the same time, the shaking component 6 can rigidly support the lower mold 3, so that it is convenient to cool after shaking. The molten metal is placed in the inner cavity of the storage barrel 51, and the top cover 52 is used for heat insulation to maintain the temperature of the molten metal in the inner cavity of the storage barrel 51. The operation of the cylinder 53 drives the piston rod 54 to expand and contract in the inner cavity of the cylinder 53, and the molten metal is quantitatively discharged through the discharge mechanism 55. The buffer mechanism 56 is used for buffering the raw materials to prevent the molten metal from being discharged during the discharge process. The high-temperature molten metal splashes everywhere, and the adjusting mechanism 57 is used to adjust the quantitative size. The shaking mechanism 58 is used to generate shaking during the feeding process so that the raw materials can fall completely, thereby improving the material precision and accuracy. The height of the shaking mechanism 62 and the supporting mechanism 63 is adjusted by the adjusting mechanism 61. The shaking mechanism 62 is used to shake the lower mold 3 and the upper mold 4 so that the molten metal is quickly mixed into the mold cavity. The upper mold 4 is used for rigid support, which is convenient for standing still after shaking to prevent shaking during the cooling process. The adjustment of the adjusting mechanism 61 drives the button 64 to contact the slider 67, which is convenient for driving the shaking mechanism 62 to shake. The second threaded rod 66 is used to adjust the distance of the slider 67 in the inner cavity of the adjusting frame 65, so that the button 64 of the adjusting mechanism 61 can contact the slider 67 when the adjusting mechanism 61 is raised and lowered, driving the shaking mechanism 62 to shake the lower mold 3, thereby improving production efficiency.
