Description

Technical Field

[0001] This utility model belongs to the field of casting equipment, and in particular relates to a cover plate device that is not prone to sand accumulation. Background Technology

[0002] In the field of casting equipment, sand easily falls onto the mold plate during the molding process. Workers need to clean it after each mold is made, which is quite troublesome and time-consuming. In order to ensure that the mold plate is clean and free of other debris for a long time, the mold plate needs to be covered during the molding process, i.e., a cover plate device.

[0003] Currently, the cover plate device of the molding machine is of the linear guide rail or linear bearing type. Scattered sand can easily fall onto the linear guide rail or linear bearing, causing sand accumulation, which can lead to damage to the linear guide rail or linear bearing. Therefore, how to make the cover plate device have a long service life, run smoothly, and save operating costs is a problem that needs to be solved. Summary of the Invention

[0004] To solve the above-mentioned technical problems, a cover plate device with long service life, space saving, stable and reliable performance and not prone to sand accumulation is provided.

[0005] The technical solution adopted by this utility model is a cover plate device that is not prone to sand accumulation, including a bracket, a cylinder, a long end cover, a shaft support, a cover plate fixing connecting plate, a cover plate, a cover plate fixing plate, a cover plate shaft, a cylinder connecting block, a round end cover, a rotating wheel, a shaft end retaining ring, an oil seal, a deep groove ball bearing, and a pin. The cylinder is installed at the lower part of the bracket and is connected to the cover plate fixing connecting plate through the cylinder connecting block. The shaft support is installed on the side of the bracket, and the cover plate shaft is fixed by two shaft supports. The long end cover is installed on the side of one of the shaft supports and is connected to the cover plate shaft by screws. The cover plate is installed on the cover plate fixing connecting plate, and the cover plate fixing plate is installed on the cover plate. The pin is installed inside the cover plate fixing connecting plate and is connected by a shaft end retaining ring and screws. The rotating wheel is between the two cover plate shafts. The deep groove ball bearing is installed between the pin and the rotating wheel. The round end cover is installed on the side of the rotating wheel, and the oil seal is installed on the other side of the rotating wheel.

[0006] Furthermore, the cover plate is made of plexiglass.

[0007] Furthermore, the cover plate fixing plate is made of carbon fiber.

[0008] Furthermore, the cover plate shaft surface is chrome plated.

[0009] This utility model has significant advantages and beneficial effects compared with the prior art: This utility model's cover plate device, which is not prone to sand accumulation, uses a cylinder to drive the cover plate to move back and forth, achieving the effect of blocking sand during the molding process. Since the cover plate shaft is round, when scattered sand falls onto the cover plate shaft, it will not accumulate on the cover plate shaft, but will automatically fall onto the sand return belt at the bottom of the molding machine, eliminating the need for manual cleaning. At the same time, the structure is not easily damaged, saving costs, and is safe and reliable. Moreover, the structure is simple, saves space, has a scientific and reasonable design, and is easy to install and disassemble. Attached Figure Description

[0011] The components are: 1. Bracket; 2. Cylinder; 3. Long end cover; 4. Shaft support; 5. Cover plate fixing connecting plate; 6. Cover plate; 7. Cover plate fixing plate; 8. Cover plate shaft; 9. Cylinder connecting block; 10. Round end cover; 11. Rotating wheel; 12. Shaft end retaining ring; 13. Oil seal; 14. Deep groove ball bearing; 15. Pin. Detailed Implementation

[0012] The following detailed description, in conjunction with the accompanying drawings and preferred embodiments, describes the specific implementation methods, structures, features, and effects provided by this utility model.

[0013] The technical solution adopted by this utility model is a cover plate device that is not prone to sand accumulation, including a bracket 1, a cylinder 2, a long end cover 3, a shaft support 4, a cover plate fixing connecting plate 5, a cover plate 6, a cover plate fixing plate 7, a cover plate shaft 8, a cylinder connecting block 9, a round end cover 10, a rotating wheel 11, a shaft end retaining ring 12, an oil seal 13, a deep groove ball bearing 14, and a pin 15; the cylinder 2 is installed at the lower part of the bracket 1, and the cylinder 2 is connected to the cover plate fixing connecting plate 2 through the cylinder connecting block 9; the shaft support 4 is installed on the side of the bracket 1, and the cover plate shaft 5 is connected to two cylinders... Shaft support 4 is fixed, long end cover 3 is installed on the side of one of the shaft support 4 and connected to cover plate shaft 5 by screws, cover plate 6 is installed on cover plate fixing connecting plate 2, cover plate fixing plate 7 is installed on cover plate 6, pin shaft 15 is installed inside cover plate fixing connecting plate 2 and connected by shaft end retaining ring 12 and screws, rotating wheel 11 is between two cover plate shafts 8, deep groove ball bearing 14 is installed between pin shaft 15 and rotating wheel 11, round end cover 10 is installed on the side of rotating wheel 11, and oil seal 13 is installed on the other side of rotating wheel 11.

[0014] Furthermore, the cover plate 6 is made of plexiglass.

[0015] Furthermore, the material of the cover plate fixing plate 2 is carbon fiber.

[0016] Furthermore, the surface of the cover plate shaft 8 is chrome plated.

[0017] The working principle of this utility model is as follows: Normally, cylinder 2 is in the extended state, and cover plate 6 covers the mold plate. When the mold plate needs to work, it moves upward to connect the mold, and cylinder 2 retracts. Through cylinder connecting block 9, it drives cover plate 6 to move so that it no longer covers the mold plate and does not affect the upward movement of the mold plate. When the mold plate finishes working, it returns to its original position, and cylinder 2 extends to the initial position. Cylinder connecting block 9 drives cover plate 6 back to its original position to continue covering the mold plate.

[0018] This utility model has significant advantages and beneficial effects compared with the prior art: This utility model's cover plate device, which is not prone to sand accumulation, uses a cylinder to drive the cover plate to move back and forth, achieving the effect of blocking sand during the molding process. Since the cover plate shaft is round, when scattered sand falls onto the cover plate shaft, it will not accumulate on the cover plate shaft, but will automatically fall onto the sand return belt at the bottom of the molding machine, eliminating the need for manual cleaning. At the same time, the structure is not easily damaged, saving costs, and is safe and reliable. Moreover, the structure is simple, saves space, has a scientific and reasonable design, and is easy to install and disassemble.
