Description

Technical Field

[0001] This utility model relates to the field of aluminum die casting technology, specifically a precision aluminum die casting demolding mechanism. Background Technology

[0002] In the aluminum die casting manufacturing industry, the demolding process plays a decisive role in product quality and production efficiency.

[0003] Traditional demolding mechanisms typically use multiple independent power sources to control the opening and closing of the mold and the ejection of the die casting. This not only leads to high costs but also increases the probability of failure and maintenance difficulty. At the same time, due to the difficulty in accurately controlling the coordination between the power sources, uneven stress on the die casting is likely to occur during the demolding process, resulting in defects such as deformation, surface scratches, or even cracks, which seriously affects the product yield.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on the existing aluminum die-casting demolding mechanisms. Utility Model Content

A circular plate is attached to the top of the second movable plate. A push rod is fixed at the center of the top of the circular plate. The upper end of the push rod is located inside the through groove. The through groove is opened at the bottom of the lower mold and inside the table. A spring is nested at the lower end of the push rod. The upper end of the spring is fixedly connected to the bottom of the table, and the lower end of the spring is fixedly connected to the top of the circular plate.

[0024] A pressing mechanism is provided on the outer side of the first rotating shaft 7 between the platform 3 and the top plate 5;

[0025] An ejection mechanism is provided on the outer side of the first rotating shaft 7 between the base 1 and the platform 3.

[0026] The pressing mechanism includes a first movable plate 8. The first movable plate 8 is located on the outer side of the first rotating shaft 7 between the platform 3 and the top plate 5. An upper mold 9 is fixed at the center of the bottom of the first movable plate 8. The upper mold 9 is located directly above the lower mold 6. There are two first rotating shafts 7 symmetrically distributed about the central axis of the first movable plate 8. The first movable plate 8 and the first rotating shaft 7 are threadedly connected, and the threads on the two first rotating shafts 7 are set in the same direction. By using the threaded connection between the first movable plate 8 and the first rotating shaft 7, the upper mold 9 is guaranteed to rise and fall smoothly, improve the mold closing accuracy, and help improve the forming quality of aluminum die castings.

[0027] The ejection mechanism includes a second movable plate 14. The second movable plate 14 is located on the outer side of the first rotating shaft 7 between the base 1 and the table 3. A circular plate 15 is attached to the top of the second movable plate 14. A push rod 16 is fixed at the center of the top of the circular plate 15. The upper end of the push rod 16 is located inside the through groove 17, which is opened at the bottom of the lower mold 6 and inside the table 3. A spring 18 is nested at the lower end of the push rod 16. The upper end of the spring 18 is fixedly connected to the bottom of the table 3, and the lower end of the spring 18 is fixedly connected to the top of the circular plate 15. The second movable plate 14 and the first rotating shaft 7 are threadedly connected, and the push rod 16 is slidably connected to the through groove 17.

[0030] Working principle: When using this precision aluminum die casting demolding mechanism, the aluminum die casting sheet is first placed in the lower mold 6. Then, the servo motor 13 is started by the controller 19. The servo motor 13 drives the first rotating shaft 7 to rotate forward. The first rotating shaft 7 drives another first rotating shaft 7 to rotate forward through the first gear 10, the second rotating shaft 11, and the second gear 12. This causes the first movable plate 8 to move downward under the action of the threaded transmission, which drives the upper mold 9 and the lower mold 6 to close the mold, thus completing the die casting process of the aluminum die casting sheet.

[0031] After die casting is completed, the servo motor 13 is reversed by the controller 19, the first rotating shaft 7 drives the second movable plate 14 to move upward, and the ejector rod 16 pushes the formed aluminum die casting out of the lower mold 6;

[0032] After ejection, the aluminum die-casting is manually removed from the ejector rod 16, and then the servo motor 13 is restarted to repeat the above molding and ejection process to achieve continuous production.
