[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] like Figures 1 to 10 As shown, the present invention provides a regular aluminum single-panel casting mold, including a base plate 1, mold feet 2 symmetrically fixed to the top two sides of the base plate 1, a lower mold base 3 fixed to the top of the mold feet 2, an upper mold base 4 attached to the top of the lower mold base 3, a top plate 5 fixed to the top of the upper mold base 4, and an ejection mechanism provided on the base plate 1.

[0030] The ejection mechanism includes a servo motor 22, a lead screw 23, an ejector rod 11, and an ejector pin 12. The servo motor 22 is fixedly installed at the top center of the base plate 1. The output end of the servo motor 22 is fixedly connected to the lead screw 23. A support plate 24 is rotatably connected to the top of the lead screw 23. The support plate 24 is fixedly connected to the top of the base plate 1 via four support rods 25. A sliding sleeve 26 is connected to the lead screw 23 via a lead screw nut pair. Multiple connecting plates 27 are fixedly connected to the side wall of the sliding sleeve 26. The connecting plates 27 are connected to the ejector pin 12. The top of the ejector plate 7 is fixedly connected, the bottom of the ejector plate 7 is fixedly connected to the fixing plate 6, the top of the ejector plate 7 is provided with the fixing plate 8, the top of the fixing plate 8 is fixedly connected to the ejector plate 9, a plurality of push rods 11 are fixedly connected to both the ejector plate 7 and the ejector plate 9, the top of the push rod 11 is fixedly connected to the push pin 12, the push pin 12 is provided with a protective sleeve 13, the push rod 11 on the ejector plate 7 passes through the fixing plate 8 and the ejector plate 9, and a support assembly is provided between the ejector plate 7 and the fixing plate 8.

[0031] This application takes into account that the ejector pins 12 in the casting mold are prone to wear and tear after long-term use, which can lead to dimensional deviations. This not only makes it impossible to distribute the force evenly during the ejection action, causing local dimensional deviations in the aluminum panel and affecting the casting quality of the product, but also leaves ejector pin marks or scratches of varying depths on the surface of the aluminum panel. This requires workers to replace the worn ejector pins 12 in a timely manner. However, the disassembly process of the ejector pins 12 is relatively cumbersome, which affects the overall efficiency of the casting process. Therefore, this application provides a protective sleeve 13 on the ejector pins 12 to protect them. After a period of use, the protective sleeve 13 can be quickly replaced, which can achieve the goal of not affecting the ejection action and avoiding the cumbersome process of disassembling the ejector pins 12.

[0032] During operation, the servo motor 22 drives the lead screw 23 to rotate, causing the sliding sleeve 26 to drive the fixed plate 6, ejector plate 7, fixed plate 8 and ejector plate 9 to slide upward together. This allows the ejector pins 12 on ejector plate 7 and ejector plate 9 to complete a secondary ejection action with the cooperation of the support components. When the worn protective sleeve 13 needs to be replaced, the operator only needs to remove the protective sleeve 13 and install a new protective sleeve 13 on the ejector pin 12.

[0033] The top of the push rod 11 has two vertical grooves 14 and one annular groove 15. The annular groove 15 is connected to the bottom of the vertical groove 14. The top of the inner wall of the annular groove 15 has two symmetrical slots 16. The inner wall of the sheath 13 is in contact with the outer wall of the push pin 12. The bottom of the inner wall of the sheath 13 has two symmetrically fixed limit blocks 17. The inner cavity of the limit block 17 has a sliding block 18. A spring is fixed between the block 18 and the inner cavity wall of the limit block 17. The end of the block 18 away from the spring extends to the outside of the limit block 17 and is conical. The slots 16 are adapted to the block 18. The limit block 17 is adapted to both the vertical groove 14 and the annular groove 15.

[0034] During operation, when replacing the worn sheath 13, the operator first rotates the worn sheath 13, causing the locking block 18 on it to slide out of the slot 16 and compress the spring 1 until the limiting block 17 rotates and slides to the point where the vertical groove 14 and the annular groove 15 connect. The worn sheath 13 can then be directly slid up to complete the disassembly. After that, the limiting block 17 of the new sheath 13 is slid down from the vertical groove 14 until the limiting block 17 slides into the annular groove 15. Then, the sheath 13 is rotated again, causing the locking block 18 to retract into the limiting block 17 and compress the spring 1 until the limiting block 17 rotates to the slot 16. At this point, the locking block 18 is pushed into the slot 16 by the elastic force of the spring 1, thus locking the limiting block 17 and fixing the sheath 13 onto the ejector pin 12. This structure design ensures that the ejection action is not affected and also protects the ejector pin 12, making it convenient for the operator to quickly disassemble and replace the sheath 13.

[0035] The support assembly includes a fixed sleeve 31 and a telescopic rod 32. Multiple fixed sleeves 31 are uniformly fixed to the top of the ejector plate 7. The telescopic rod 32 is slidably connected inside the fixed sleeve 31. The top of the telescopic rod 32 is fixed to the bottom of the fixed plate 8. A spring 2 is fixed between the fixed sleeve 31 and the fixed plate 8. The spring 2 is sleeved on the telescopic rod 37.

[0036] During operation, when the servo motor 22 starts and drives the ejector plate 7 to slide upward, the ejector plate 9 slides upward under the action of the fixed sleeve 31, the telescopic rod 32 and the spring 2, completing one ejection action. When the ejector plate 9 is in contact with the bottom of the lower mold base 3, the ejector plate 7 continues to slide upward, the telescopic rod 32 retracts into the fixed sleeve 31, and the spring 2 is compressed, completing the second ejection action. Through two ejection actions, the aluminum plate can be separated from the cavity or the gate can be cut off before complete demolding. This avoids deformation or tearing caused by a single ejection and realizes the phased release of demolding resistance.

[0037] Guide plates 10 are fixedly connected to both sides of the base plate 1. Guide groove 19 and guide groove 21 are provided on the guide plates 10. Guide blocks 28 are fixedly connected to both sides of the fixed plate 6. Guide blocks 28 are slidably connected to guide groove 19. Guide blocks 30 are fixedly connected to both sides of the ejector plate 9. Guide blocks 30 are slidably connected to guide groove 21.

[0038] During operation, the sliding engagement between guide block 28 and guide groove 19 facilitates the auxiliary guidance of the ejection action of ejector plate 7, and the sliding engagement between guide block 30 and guide groove 21 facilitates the auxiliary guidance of the ejection action of ejector plate 9.

[0039] The guide plate 10 has a limiting groove 20, the top of the inner wall of the limiting groove 20 is inclined, and the two sides of the fixing plate are provided with a storage groove 33. A wedge block 29 is slidably connected in the storage groove 33. The bottom end of the wedge block 29 extends to the bottom of the fixing plate 8 and is fixedly connected to the mounting frame 34. Multiple top support blocks 35 are evenly fixed to both sides of the inner wall of the mounting frame 34. The outer wall of the fixing sleeve 31 is symmetrically provided with protrusions. The top support blocks 35 fit with the protrusions. A telescopic rod 37 is fixedly connected to the side of the mounting frame 34 away from the wedge block 29. The telescopic rod 37 is slidably connected to the inner cavity of the fixing sleeve 36. The fixing sleeve 36 is fixedly connected to the bottom of the fixing plate 8. A spring 3 is fixed between the telescopic rod 37 and the inner cavity wall of the fixing sleeve 36.

[0040] During operation, when the servo motor 22 starts and drives the ejector plate 7 to slide upward, the ejector plate 9 slides upward accordingly. At this time, the wedge block 29 slides within the limiting groove 20, and the spring 3 inside the fixing sleeve 36 is in its natural state, causing the top support block 35 on the mounting frame 34 to be engaged between the protrusion of the fixing sleeve 31 and the fixing plate 8. When the wedge block 29 slides upward to the inclined surface within the limiting groove 20, the wedge block 29 is compressed and slides into the receiving groove 33, driving the mounting frame 34 to slide together towards the fixing sleeve 36. The top support block 35 then disengages from the protrusion on the fixing sleeve 31. When the spring is compressed, and the top support block 35 is completely disengaged from the protrusion on the fixed sleeve 31 and the guide block 30 slides to the top of the guide groove 21, the ejector plate 7 continues to slide upward. At this time, the telescopic rod 32 retracts into the fixed sleeve 31, and the ejector pin 12 on the ejector plate 7 achieves a second ejection. By setting the fixed frame and the top support block 35, it is convenient to limit the ejector plate 9 during one ejection action, ensuring the synchronization of the ejector plate 7 and the ejector plate 9 during one ejection action, and preventing the ejector pin 12 on the ejector plate 9 from failing to complete one ejection action due to demolding resistance.

[0041] Both sides of the bottom of the vertical groove 14 are chamfered;

[0042] During operation, chamfers are provided on both sides of the bottom of the vertical groove 14 to facilitate the smooth rotation of the limiting block 17 into the annular groove 15 when replacing the new sheath 13.

[0043] Working principle: When replacing the worn sheath 13, the operator first rotates the worn sheath 13, causing the locking block 18 on it to slide out of the slot 16 and compress the spring 1 until the limiting block 17 rotates and slides to the point where the vertical groove 14 and the annular groove 15 connect. The worn sheath 13 can then be directly slid upwards to complete the disassembly. Next, the limiting block 17 of the new sheath 13 is slid down from the vertical groove 14 until it slides into the annular groove 15. The sheath 13 is then rotated again, causing the locking block 18 to retract into the limiting block 17 and compress the spring 1 until the limiting block 17 rotates to the slot 16. At this point, the locking block 18, under the elastic force of the spring 1, slides into the slot 16, locking the limiting block 17. This fixes the sheath 13 onto the ejector pin 12. When the servo motor 22 starts and drives the ejector plate 7 to slide upwards, the ejector plate 9 follows... As the wedge 29 slides upward, it completes one ejection action. At this time, the wedge block 29 slides in the limiting groove 20, the spring 3 in the fixed sleeve 2 36 is in its natural state, and the top support block 35 on the mounting frame 34 is stuck between the protrusion of the fixed sleeve 1 31 and the fixed plate 2 8. When the wedge block 29 slides upward to the inclined surface in the limiting groove 20, the wedge block 29 is squeezed and slides into the receiving groove 33, and drives the mounting frame 34 to slide together to the side of the fixed sleeve 2 36. The top support block 35 then disengages from the protrusion on the fixed sleeve 1 31, and the spring 3 is compressed. When the top support block 35 completely disengages from the protrusion on the fixed sleeve 1 31 and the guide block 2 30 slides to the top of the guide groove 2 21, the ejector plate 1 7 continues to slide upward. At this time, the telescopic rod 1 32 retracts into the fixed sleeve 1 31, and the ejector pin 12 on the ejector plate 1 7 achieves a second ejection.
