Description

Technical Field

[0001] This invention relates to the field of die-casting equipment technology, specifically to a server base die-casting equipment that facilitates the ejection of die-cast parts without damage. Background Technology

[0002] In the die casting process, molten metal fills the mold cavity under high pressure, cools and solidifies, and adheres to the mold. The cavity is sealed, and the bottom of the casting is close to a vacuum with the bottom of the mold cavity, generating a negative pressure adsorption force. Traditional ejection mechanisms need to overcome the adhesion force between the workpiece and the mold sidewall and the negative pressure, making demolding difficult and easily causing the casting to deform, scratch, or be damaged.

[0003] Traditional die casting equipment typically employs a single ejection structure design. When the die casting is clamped to the mold, the single ejection force is transmitted to the surface of the die casting through a limited number of ejector rods, which can easily lead to stress concentration on the surface of the die casting, resulting in deformation and damage in localized areas of the die casting surface.

[0004] Patent CN117773064B discloses a die casting equipment that facilitates the non-destructive ejection of die castings. The patent achieves stable ejection of die castings. Multiple air outlets ensure uniform distribution of compressed air for uniform gas ejection and demolding of the die castings. When the compressed air is blown onto the die castings, it cools the die castings.

[0005] The aforementioned patent addresses the issues that during the ejection process, ejector rods cannot stably eject the die casting, and that a single ejector rod is only placed at key nodes and cannot cover the die casting. Furthermore, using multiple ejector rods can cause multiple impact damage to the die casting. However, there is still room for optimization in the ejection of die castings. This application achieves staged ejection, solving problems such as casting deformation and tearing caused by excessive ejection force at one time.

[0006] Therefore, this application proposes a server base die-casting device that enables staged ejection to facilitate the non-damaging ejection of die-cast parts. Summary of the Invention

[0035] Please see Figure 1 , Figure 2 and Figure 5 One embodiment of the present invention provides a server base die-casting device that facilitates the damage-free ejection of die-cast parts, comprising a die-casting body 1, a second telescopic device 5 fixedly connected to the bottom of the die-casting body 1, a lifting plate 6 fixedly connected to the top of the outer wall of the second telescopic device 5, the lifting plate 6 being movably fitted onto the outer wall of an ejector rod 9, a guide block 7 slidably connected to the outer wall of the ejector rod 9, a first abutting ring 11 and a second abutting ring 12 fixedly connected to the outer wall of the guide block 7, the first abutting ring 11 being located below the second abutting ring 12, and the ejector rod 9 being connected to a displacement frame 48 via a return spring 46. The inner wall of the displacement frame 48 is slidably connected to an abutment block 13, and the abutment block 13 is connected to the displacement frame 48 through a second spring 14. The inner wall of the ejector rod 9 is fixedly connected to an inclined block 47. The outer wall of the die-casting body 1 is fixedly connected to a lower mold 2, and the side wall of the ejector rod 9 is fixedly connected to an ejector plate 15. The top of the outer wall of the die-casting body 1 is fixedly connected to a first telescopic device 4, the bottom of the outer wall of the first telescopic device 4 is fixedly connected to an upper mold 3, and the side wall of the lower mold 2 is fixedly connected to a positioning ring block 43, which contacts the ejector plate 15. The outer wall of the ejector rod 9 is symmetrically provided with opening slots 45.

[0036] Furthermore, after the upper mold 3 and lower mold 2 are preheated and coated with a release agent, the first telescopic device 4 drives the upper mold 3 to move towards the lower mold 2 for mold closing. The aluminum alloy is heated to a molten state and injected into the upper mold 3 and lower mold 2. After the molten metal cools and solidifies within the upper mold 3 and lower mold 2, the first telescopic device 4 drives the upper mold 3 to separate from the lower mold 2. The second telescopic device 5 is then activated, causing the lifting plate 6 to move upwards. The lifting plate 6 moves along the guide block 7, gradually approaching and contacting the contact block 13. The contact block 13 then drives the displacement frame 48 and the second spring 14 to move upwards. The displacement frame 48 compresses the return spring 46, and at the same time, the displacement frame 48 drives the return spring 46 to apply an upward force to the ejector rod 9, causing the ejector rod 9 to tend to move upward. The ejector rod 9 applies an upward force to the ejector plate 15, causing the ejector plate 15 to tend to move upward. The ejector plate 15 applies an initial ejection force to the die casting in the lower mold 2, causing the die casting to initially loosen in the lower mold 2. If the ejection force applied by the ejector plate 15 at this time can make the die casting smoothly detach from the lower mold 2, the lifting plate 6 drives the contact block 13, the displacement frame 48, and the return spring 46 to cause the ejector rod 9 and the ejector plate 15 to separate the die casting from the lower mold 2.

[0037] If the ejection force applied by the ejector plate 15 is insufficient to smoothly remove the die-casting part from the lower mold 2, the displacement frame 48 continues to move within the opening slot 45. The displacement frame 48 continues to compress the return spring 46. When the contact block 13 contacts the inclined block 47, during the upward movement of the contact block 13, the inclined block 47 drives the contact block 13 to compress the second spring 14, causing the contact block 13 to gradually move into the displacement frame 48. The contact area between the contact block 13 and the lifting plate 6 gradually decreases. When the contact block 13 no longer contacts the lifting plate 6, the lifting plate 6 no longer drives the contact block 13. The lifting plate 6 continues to move upward, and the contact block 13 moves downward relative to the lifting plate 6, allowing the contact block 13 to pass through the through slot 44 on the lifting plate 6. The lifting plate 6 gradually approaches and contacts the second contact ring 12. The lifting plate 6 applies an upward force to the second contact ring 12, and the second contact ring 12 applies an upward force to the ejector rod 9, ejecting the part. Rod 9 applies an upward force to ejector plate 15, causing ejector plate 15 to continuously eject the die casting a second time, ensuring the die casting is smoothly removed. Lifting plate 6 drives contact block 13 to apply a short-term ejection force to the die casting, causing it to loosen initially. Then, lifting plate 6 drives second contact ring 12 to apply a continuous ejection force to the die casting, causing it to completely detach from lower mold 2, avoiding deformation or local tearing caused by a single ejection. By decomposing the single ejection action into two stages, an intermittent force is applied during the first ejection, causing a slight relative displacement between the die casting and lower mold 2, achieving initial separation. When the initial force cannot eject, there is a short period without applying force, allowing the clamping force between the die casting and lower mold 2 to be released. During the second ejection, a continuous force is applied, causing the die casting to completely detach from the mold, avoiding problems such as casting deformation and tearing caused by excessive single ejection force.

[0038] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4One embodiment of the present invention provides a server base die-casting device that facilitates the non-damaging ejection of die-cast parts. A contact block 19 is movably mounted on the lower mold 2. A connecting plate 20 is fixedly connected to the bottom of the outer wall of the contact block 19. A connecting rod 24 is fixedly connected to the bottom of the outer wall of the connecting plate 20, penetrating a base plate 27. A cavity structure 17 is fixedly connected to the outer wall of the base plate 27. The lower mold 2 is fixedly connected to the top of the outer wall of the cavity structure 17. A movable plug 28 is slidably connected to the inner wall of the cavity structure 17. A movable body 22 is fixedly connected to the bottom of the outer wall of the movable plug 28. The cavity structure 17 is slidably connected to the outer wall of the movable body 22. A third spring 25 is fixedly connected to the side wall of the movable body 22. A bottom spring 25 is fixedly connected to the side wall of the third spring 25. A fourth spring 26 is fixedly connected to the side wall of the plate 27 and the connecting plate 20. A base plate 27 is fixedly connected to the side wall of the fourth spring 26. A touch plate 23 is fixedly connected to the bottom of the outer wall of the connecting rod 24. The touch plate 23 is in contact with the cam 18. The cam 18 is fixedly connected to the outer wall of the rotating shaft 29. A die-casting body 1 is rotatably connected to the side wall of the rotating shaft 29. A deflection block 49 is fixedly connected to the outer wall of the rotating shaft 29. A connecting groove 21 is provided in the lower mold 2. A coil spring structure 30 is provided on the outer wall of the rotating shaft 29. A die-casting body 1 is fixedly connected to the side wall of the coil spring structure 30. A first stop block 10 is fixedly connected to the side wall of the die-casting body 1. The first stop block 10 is in contact with the deflection block 49. A second stop block 31 is fixedly connected to the side wall of the die-casting body 1.

[0039] Furthermore, during the ejection of the die-cast part, the second telescopic device 5 is activated. The second telescopic device 5 drives the lifting plate 6 to move upward. The lifting plate 6 drives the deflector block 49 to rotate around the rotating shaft 29. The deflector block 49 drives the rotating shaft 29 to rotate. The rotating shaft 29 drives the cam 18 to rotate. As a result, the contact position between the cam 18 and the moving body 22 and the contact plate 23 gradually moves from the outer contour surface of the cam 18 closest to the rotating shaft 29 to the outer contour surface of the cam 18 farthest from the rotating shaft 29. This causes the cam 18 to drive the moving body 22 to move upward and the contact plate 23 to move downward. The contact plate 23 then drives... The connecting rod 24 moves, causing the connecting plate 20 to move as well. The connecting plate 20 compresses the fourth spring 26, causing the contact block 19 to move downwards, thus removing the contact block 19 from close contact with the lower mold 2 and unblocking the connecting groove 21. Simultaneously, the movable body 22 compresses the third spring 25, causing the movable plug 28 to move within the cavity structure 17. The movable plug 28 moves upwards, compressing the gas within the cavity structure 17. When the connecting groove 21 is no longer blocked, the gas within the cavity structure 17 passes through the connecting groove 21, thereby blowing airflow onto the die-casting part, utilizing the uniformity of the gas to break the blockage. The static friction between the die-casting part and the lower mold cavity 2 causes the casting part to loosen. During the rotation of the deflector block 49 by 90°, the contact position between the lifting plate 6 and the deflector block 49 gradually moves from the top of the lifting plate 6 to the side of the lifting plate 6. When the side of the lifting plate 6 contacts the deflector block 49, the lifting plate 6 no longer drives the deflector block 49 to rotate. The lifting plate 6 slides along the side wall of the deflector block 49. The lifting plate 6 continues to move upward. The second stop block 31 and the lifting plate 6 abut against the deflector block 49, keeping the deflector block 49 in a continuously vertical state. The lifting plate 6 drives the abutment block 13 or the second abutment ring 12 to make the ejector rod 9 eject... Plate 15 pushes the loosened die-cast part away from the lower mold 2; when the lifting plate 6 returns to its original position, under the action of the coil spring structure 30, the coil spring structure 30 drives the rotating shaft 29 to rotate, and the rotating shaft 29 drives the deflection block 49 to rotate. The arc surface of the deflection block 49 contacts the first stop 10, so that while the deflection block 49 contacts the first stop 10, the deflection block 49 rotates around the rotating shaft 29. When the arc surface of the deflection block 49 moves to the plane at the position where it contacts the first stop 10, the first stop 10 abuts against the deflection block 49, so that the deflection block 49 remains in a horizontal state, so as to ensure that the subsequent lifting plate 6 can drive the deflection block 49.

[0040] By first breaking static friction with airflow, the force required for mechanical ejection is reduced, thus decreasing the load and wear on the ejector rod 9 and ejector plate 15. This allows the mechanical ejection to provide auxiliary force after the die-casting part loosens, reducing the risk of whitening or deformation of the die-casting part due to localized stress concentration. For server bases with large projected areas and strong clamping forces, airflow is used to loosen the die-casting part before mechanical ejection, avoiding the risk of insufficient ejection force in pure air ejection. This solves the problem that the total ejection force of pure air ejection is limited by the air source pressure and the effective pressure area of ​​the casting part. It also avoids the problem of ejection marks and deformation caused by high localized stress that are easily generated by pure mechanical ejection.

[0041] Please see Figure 2 , Figure 3 , Figure 4 and Figure 7 The present invention provides an embodiment of a server base die-casting device that facilitates the undamaged ejection of die-cast parts. A contact plate 37 is slidably connected to the inner wall of the contact block 19, and a guide post 38 is slidably connected to the inner wall of the contact plate 37. A guide groove 40 is formed on the side wall of the contact plate 37, and the guide groove 40 is movably fitted onto the outer wall of the guide post 38. A contact block 19 is fixedly connected to the side wall of the guide post 38, and a compression spring 42 is fixedly connected to the side wall of the contact block 19. The contact plate 37 is fixedly connected to the side wall of the compression spring 42, and the compression spring 42 is movably fitted onto the outer wall of the guide post 38. A first locking block 39 is fixedly connected to the side wall of the contact plate 37, and a second locking block 41 is fixedly connected to the top of the outer wall of the connecting plate 20. The first locking block 39 contacts the second locking block 41, and the contact block 19 is slidably connected to the side wall of the second locking block 41.

[0042] Furthermore, during the ejection of the die-cast part, the second telescopic device 5 drives the lifting plate 6 to move, the lifting plate 6 drives the deflection block 49 to rotate, the deflection block 49 drives the rotating shaft 29 to rotate, the rotating shaft 29 drives the cam 18 to rotate, the cam 18 drives the movable body 22 to move upward and the contact plate 23 to move downward, so that the movable body 22 and the contact plate 23 move away from each other. The movable body 22 drives the movable plug 28 to compress the gas in the cavity structure 17, the contact plate 23 drives the connecting rod 24 and the connecting plate 20 to move, the connecting plate 20 drives the second locking block 41 to move downward, the second locking block 41 drives the first locking block 39 to move, the first locking block 39 drives the contact plate 37, so that the contact plate 37 moves downward along the guide post 38, the contact plate 37 compresses the compression spring 42, and the contact plate 37 drives the guide post 38 and the contact block 19 to move downward; when there is a relative vacuum environment between the bottom of the die-cast part and the mold cavity of the lower mold 2. If the contact block 19 may not be able to move down under negative pressure, then under the action of the contact plate 37, the first locking block 39, and the second locking block 41, the connecting plate 20 will drive the second locking block 41, the first locking block 39, and the contact plate 37 to open the gap between the contact block 19 and the lower mold 2. Since the top area of ​​the contact plate 37, which is flush with the lower mold 2, is small, and under the squeezing action of the compressed gas in the connecting groove 21, the suction effect of the negative pressure on the contact plate 37 can be offset, so that the contact plate 37 can move along the guide post 38, thereby opening the gap. This allows the compressed gas in the connecting groove 21 to blow some gas into the die casting, eliminating the negative pressure on the contact block 19, allowing the contact block 19 to move down, and further allowing the compressed gas in the connecting groove 21 to blow into the die casting, thereby eliminating the negative pressure between the die casting and the mold cavity, and breaking the static friction between the die casting and the mold cavity of the lower mold 2.

[0043] Please see Figure 2 , Figure 3 and Figure 6 One embodiment of the present invention provides a server base die-casting device that facilitates the undamaged ejection of die-cast parts. The die-casting body 1 has mounting blocks 16 symmetrically fixedly connected to its bottom. A fifth spring 50 is fixedly connected to the inner wall of the mounting blocks 16. A second translation plate 35 is fixedly connected to the top of the outer wall of the fifth spring 50. The mounting blocks 16 are slidably connected to the side wall of the second translation plate 35. A first translation plate 34 is slidably connected to the side wall of the mounting blocks 16. A first toothed plate 33 is fixedly connected to the side wall of the first translation plate 34. A transmission gear 32 is meshed with the side wall of the first toothed plate 33. The transmission gear 32 is connected to the mounting blocks 16 via a rotating shaft. A second toothed plate 36 is meshed with the side wall of the transmission gear 32. A second translation plate 35 is fixedly connected to the side wall of the second toothed plate 36. The second translation plate 35 is located directly below the lifting plate 6, and the first translation plate 34 is located directly below the touch plate 23.

[0044] Furthermore, during the ejection of the die-casting part, the second telescopic device 5 drives the lifting plate 6 to move upward. The lifting plate 6 drives the deflection block 49, the rotating shaft 29, and the cam 18. The cam 18 drives the movable body 22 and the contact plate 23. The movable body 22 and the contact plate 23 gradually move away from each other. The contact plate 23 drives the connecting rod 24, the connecting plate 20, the second locking block 41, the first locking block 39, the contact plate 37, and the contact block 19 to move downward. The connecting plate 20 compresses the fourth spring 26; the movable body 22 compresses the third spring 25. The movable body 22 drives the movable plug 28 to compress the gas in the cavity structure 17. The gas in the cavity structure 17 is blown out through the connecting groove 21, thereby blowing gas onto the die-casting part. The lifting plate 6 no longer drives the deflection block 49 to rotate and continues to move upward. The lifting plate 6 drives the abutment block 13 or the second abutment ring 12, causing the ejector rod 9 and the ejector plate 15 to push the loosened die-casting part away from the lower mold 2. When the second telescopic device 5 drives the lifting plate 6 to reset downward, when the lifting plate 6 is not in contact with the deflection block 49, the coil spring structure 30 drives the rotating shaft 29, cam 18, and deflection block 49 to reset. The third spring 25 and the fourth spring 26 release elastic potential energy. The third spring 25 drives the movable body 22 to move downward, so that the movable body 22 contacts the cam 18. By setting a one-way valve body structure in the cavity structure 17, the movable body 22 can drive the movable plug 2. 8. The fourth spring 26 moves the connecting plate 20 upward, and the connecting plate 20 moves the contact block 19 upward. The compression spring 42 releases its elastic potential energy and moves the contact plate 37 back to its original position, so that the contact plate 37 and the contact block 19 contact the lower mold 2. When the lifting plate 6 moves to the position of the second translation plate 35, the lifting plate 6 moves the second translation plate 35 downward. The second translation plate 35 moves the second toothed plate 36 within the mounting block 16. The second translation plate 35 compresses the fifth spring 50. The second toothed plate 36 drives the transmission gear 32 to rotate. The transmission gear 32 drives the first toothed plate 33 to move. The first toothed plate 33 drives the first translation plate 34. The first translation plate 34 moves closer to and touches the contact plate 23, causing the first translation plate 34 to drive the contact plate 23 to move upward. The contact plate 23 drives the connecting rod 24, connecting plate 20, second locking block 41, first locking block 39, contact plate 37, and contact block 19 to move upward, ensuring that the contact plate 23 is in close contact with the cam 18, thereby ensuring that the contact plate 37 and contact block 19 are in close contact with the lower mold 2, so that the top surface of the contact block 19 is flush with the bottom surface of the inner wall of the lower mold 2. This avoids gaps between the contact plate 37, contact block 19 and the lower mold 2 due to the weight of the components or the failure of the fourth spring 26, which would cause molten metal to enter the gaps, resulting in a decrease in the quality of the die casting and failure of the airflow purging.

[0045] Please see Figure 2 , Figure 3 and Figure 4This invention provides an embodiment of a server base die-casting device that facilitates the damage-free ejection of die-cast parts. A second telescopic device 5 is fixedly connected to the bottom of the die-casting body 1. A lifting plate 6 is fixedly connected to the top of the outer wall of the second telescopic device 5. The lifting plate 6 is movably fitted onto the outer wall of the ejector rod 9. A guide block 7 is slidably connected to the outer wall of the ejector rod 9. A first abutment ring 11 and a second abutment ring 12 are fixedly connected to the outer wall of the guide block 7. A first telescopic device 4 is fixedly connected to the top of the outer wall of the die-casting body 1. An upper mold 3 is fixedly connected to the bottom of the outer wall of the first telescopic device 4. A positioning ring block 43 is fixedly connected to the side wall of the lower mold 2, and the positioning ring block 43 contacts the ejector plate 15. A first spring 8 is fixedly connected to the inner wall of the guide block 7, and the ejector rod 9 is fixedly connected to the side wall of the first spring 8.

[0046] Furthermore, when the second telescopic device 5 drives the lifting plate 6 to reset downwards, the lifting plate 6 drives the first abutment ring 11 to move downwards, the first abutment ring 11 drives the ejector rod 9 to move downwards, the ejector rod 9 compresses the first spring 8, and the ejector rod 9 drives the ejector plate 15 to move downwards, so that the ejector plate 15 contacts the positioning ring block 43. When the ejector plate 15 contacts the positioning ring block 43, the top surface of the ejector plate 15 is flush with the bottom of the inner wall of the lower mold 2. The lifting plate 6 drives the first abutment ring 11, the ejector rod 9, and the ejector plate 15. When the ejector plate 15 contacts the positioning ring block 43, the lifting plate 6 drives the second translation plate 35, the second toothed plate 36, the transmission gear 32, the first toothed plate 33, the first translation plate 34, and the contact plate 23. The contact plate 23 is in contact with the cam 18.

[0047] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 The present invention provides an embodiment of a server base die-casting device that facilitates the undamaged ejection of die-cast parts. The bottom of the die-casting body 1 is fixedly connected to a second telescopic device 5, and the top of the outer wall of the second telescopic device 5 is fixedly connected to a lifting plate 6. The lifting plate 6 is movably fitted onto the outer wall of the ejection rod 9. The outer wall of the ejection rod 9 is slidably connected to a guide block 7. The outer wall of the guide block 7 is fixedly connected to a first abutment ring 11 and a second abutment ring 12. The ejection rod 9 is provided with a reset spring 46, a displacement frame 48, an abutment block 13, a second spring 14, and an inclined block 47. The die-casting body 1 is provided with a contact block 19, a connecting plate 20, a connecting rod 24, a bottom plate 27, a cavity structure 17, a movable plug 28, a touch plate 23, a cam 18, a rotating shaft 29, and a deflection block 49.

[0048] Furthermore, by setting the abutment block 13 and the second abutment ring 12 at the position of the ejector rod 9, the airflow blown by the cavity structure 17 and the movable plug 28 can be before or after the initial ejection process of the abutment block 13, the ejector rod 9, and the ejector plate 15. When the blowing airflow is set before the initial ejection process, the airflow forms an air film between the die casting and the lower mold 2. The airflow generates a certain pressure in the mold cavity of the lower mold 2, which offsets part of the clamping force, reduces the adhesion force between the die casting and the wall of the lower mold 2, reduces the demolding resistance, makes the subsequent mechanical ejection process more gentle, and improves the success rate of the initial ejection of the abutment block 13, the ejector rod 9, and the ejector plate 15.

[0049] When the blowing airflow is set after the initial ejection process, after the initial ejection process of the contact block 13, ejection rod 9, and ejection plate 15, even if the initial force fails to eject the die casting, it will still create a small gap at the interface between the die casting and the lower mold 2. The airflow penetrates and fills the gap, using gas pressure to pry and widen the gap, thereby strengthening and expanding the breaking adhesion effect of the initial force. Alternatively, after the initial ejection, if there is local adhesion between the die casting and the lower mold 2, the airflow can further destroy the remaining adhesion force, providing auxiliary demolding force for the second ejection, ensuring that the die casting completely detaches from the mold.

[0050] Working principle: After the upper mold 3 and lower mold 2 are closed, molten metal is injected into the upper mold 3 and lower mold 2, cooled and solidified, and the upper mold 3 and lower mold 2 are separated. The second telescopic device 5 drives the lifting plate 6 to move upward. The lifting plate 6 drives the contact block 13, the displacement frame 48, the return spring 46, the ejector rod 9, and the ejector plate 15 to initially eject the die-cast part, causing it to move slightly.

[0051] The displacement frame 48 continuously compresses the return spring 46. After the contact block 13 contacts the inclined block 47, the inclined block 47 drives the contact block 13 to compress the second spring 14. The contact block 13 no longer contacts the lifting plate 6. The lifting plate 6 moves up to approach and contact the second contact ring 12. The second contact ring 12, the ejector rod 9, and the ejector plate 15 are ejected for a second time, causing the die-casting part to separate from the lower mold 2.

[0052] Before the second continuous ejection, during the upward movement of the lifting plate 6, the lifting plate 6 drives the deflection block 49, the rotating shaft 29, and the cam 18 to rotate. The cam 18 drives the moving body 22 and the contact plate 23 to gradually move away. The contact plate 23 drives the connecting rod 24, the connecting plate 20, and the contact block 19, so that the connecting groove 21 is no longer blocked. The moving body 22 drives the moving plug 28 to blow airflow onto the die casting.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
