Description

Technical Field

[0001] This invention relates to the field of automotive metal die casting, specifically to a die casting forming apparatus for automotive aluminum alloy parts. Background Technology

[0002] The main focus of automotive aluminum alloy die-casting equipment is on the development of automotive lightweighting technologies, particularly integrated aluminum alloy die-casting technology. This technology injects molten aluminum alloy into a mold under high pressure, which then rapidly cools and solidifies to create parts with complex shapes, making it suitable for producing lightweight automotive components. Integrated aluminum alloy die-casting technology can reduce the number of parts and production processes, improve manufacturing efficiency and product quality, while integrating structural performance and lightweight advantages.

[0003] In the actual aluminum alloy die casting production process, various problems often arise in the demolding process. The demolding and ejection components on existing die casting machines require additional drive force units and automated control systems to control the demolding operation. The additional drive force units and automated control systems increase the overall cost and operation and maintenance costs of the die casting machine. Furthermore, due to the integrated die casting method, the clamping force is not uniform in various parts of the casting with complex structures. In the traditional mold ejection process, the instantaneous acceleration is extremely high, and the impact force will directly act on the weak parts of the workpiece (such as the roots of reinforcing ribs and thin-walled areas), causing stress concentration to exceed the material strength limit, resulting in cracks or deformation, making it difficult to guarantee the quality of the formed aluminum alloy parts. Summary of the Invention

[0004] The purpose of this invention is to provide a die-casting apparatus for automotive aluminum alloy parts to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides a die-casting molding apparatus for automotive aluminum alloy parts, comprising a die-casting machine body, wherein four guide rails are provided inside the die-casting machine body, a fixed mold is fixedly mounted on the outer wall of the guide rails, and a movable mold is slidably mounted on the outer wall of the guide rails, and an ejector hole is symmetrically opened through one side of the fixed mold, and an ejector shell is slidably installed on the inner wall of the ejector hole.

The pre-loosening vibration mold components include a connecting rod fixedly connected to one side of the moving mold, and a drive frame fixedly connected to the other side wall of the connecting rod. During the demolding process, the drive frame intermittently impacts and loosens the ejector shell through an intermittent vibration assembly.

[0007] The ejector shell is provided with an ejector lubrication component. The ejector lubrication component includes a liquid storage cavity opened inside the ejector shell. A pusher plate is slidably connected inside the liquid storage cavity. During the demolding process, the drive frame drives the pusher plate through the extrusion and pushing assembly to continuously send the demolding liquid in the liquid storage cavity into the space between the workpiece and the mold cavity for lubrication.

[0008] The ejector shell is equipped with a demolding separation component, which includes a demolding disc rotatably connected to the ejector end face of the ejector shell. A connecting cylinder is fixedly connected to the rear end face of the demolding disc, and a sliding column is slidably connected to the inner wall of the connecting cylinder. A spring is fixedly connected to the rear end face of the sliding column. After the workpiece leaves the mold cavity, the push plate drives the demolding disc to rotate through the pressing and rotating assembly, thereby separating the workpiece from the ejector shell.

[0009] Preferably, the intermittent vibration assembly includes:

[0010] A mounting cylinder is fixedly installed on one side of the mold. A rotating rod is slidably connected to the inner wall of the mounting cylinder, and a spiral groove is opened on the outer wall of the rotating rod. A rotating rod is rotatably connected to the rear end face of the ejector shell. A transmission belt is installed between the rotating rod and the rotating rod. A connecting plate is fixedly and rotatably installed at the same end of the rotating rod and the rotating rod. The drive frame is driven by the rotating rod through the spiral groove.

[0011] Preferably, a movable ring is slidably connected to the outer wall of the rotating rod two. A spring one is fixedly connected at equal intervals to the end face of the movable ring facing the ejector shell, and a vibration ring is fixedly connected to the other end of the spring one. A circulation groove is opened on the outer wall of the rotating rod two corresponding to the movable ring, and the movable ring is driven by the rotating rod two through the circulation groove. A limiting rod is fixedly connected at equal intervals to the end face of the ejector shell facing the movable ring. The inner walls of the movable ring and the vibration ring are slidably connected to the outer walls of the limiting rods, respectively.

[0012] Preferably, the outer wall of the rotating rod is provided with a linear guide groove, and the inner wall of the linear guide groove is connected and matched with the inner wall of the spiral groove. The inner wall of the mounting cylinder is fixedly connected with a spring, and the other end of the spring is fitted and assembled with one end face of the rotating rod.

[0013] Preferably, the squeezing and pushing component includes:

[0014] A slide rod is fixedly connected to the side of the push plate facing the drive frame. The other ends of the two slide rods extend through the inside of the ejector housing to the outside. A connecting ring is fixedly connected to the extended end of the slide rod. A spring three is fitted to the outer wall of the extended end of the slide rod. One end of the spring three is fixedly connected to the outer wall of one side of the ejector housing, and the other end of the spring three is fixedly connected to one end face of the connecting ring. Through holes are opened at equal intervals on the front outer wall of the ejector housing.

[0015] Preferably, the pressing and rotating assembly includes:

[0016] A clamping plate is fixedly connected to the end face of the sliding column facing the liquid pusher plate. One end of the spring is fixedly connected to the inner wall of the connecting cylinder. Fixed rods are symmetrically fixedly connected to the outer wall of the sliding column. Inclined grooves are symmetrically opened on the outer wall of the connecting cylinder corresponding to the fixed rods.

[0017] Preferably, the side of the ejector plate facing the demolding disc has a corresponding slot on the card plate, and the shape of the card plate matches and fits the inner wall of the slot. Positioning blocks are fixedly connected to both sides of the rear end of the ejector shell.

[0018] Preferably, a drive push rod is fixedly installed on one side of the moving mold, and an injection tube is fixedly installed on one side of the fixed mold.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. During the die casting demolding process of aluminum alloy parts, the movement of the moving mold as it separates from the fixed mold can be used as a driving force to move the intermittent vibration component set on the fixed mold. This intermittent vibration is applied to the ejector shell inside the fixed mold. This vibration acts on the bottom of the workpiece that has not yet been demolded, realizing a two-stage demolding method of loosening first and then ejecting. In the first half, the movement of the moving mold drives the intermittent vibration component, causing the ejector shell to vibrate and push the workpiece with small amplitude and intermittent vibration, which breaks the static friction and micro-adhesion points between the workpiece and the mold cavity, thereby avoiding local tearing of thin-walled or complex structural parts. In the second half, the ejection mechanism begins to eject the workpiece. At this time, the workpiece has been initially loosened and can be ejected smoothly with a smaller force, thus ensuring the die casting quality of this device.

[0021] 2. During the die casting demolding process of aluminum alloy parts, the gap between the mold and the mold cavity can be filled by the extrusion and pushing component during the latter half of the formal ejection process. Throughout the entire ejection stroke, the extrusion and pushing component will be continuously extruded, and fresh demolding fluid will be continuously replenished to the moving interface, always maintaining a state of simultaneous ejection and fluid addition. Thus, during the ejection process, the fluid acts as a lubricant to reduce friction and minimize sliding damage between the workpiece and the mold cavity during demolding. On the other hand, it acts as a flexible force transmission medium to evenly distribute the ejection force on the workpiece ejection contact surface, avoiding local stress concentration, thereby ensuring the die casting quality of this device.

[0022] 3. During the die casting demolding process of aluminum alloy parts, when the ejector shell moves to its maximum stroke, the ejector shell itself is limited and cannot move forward. At this time, the extrusion and pushing component continues to move inside the ejector shell. This stroke drives a rotatable demolding disc located at the front end of the ejector shell, causing it to rotate. The rotation of the demolding disc causes the contact surface between the workpiece and the ejector shell to rotate relative to each other, thereby forcibly separating the workpiece from the ejector shell and allowing the workpiece to fall off, making it easy for workers or robotic arms to pick up, ensuring reliable part removal.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1, please refer to Figures 1-6 This invention provides a die-casting molding device for automotive aluminum alloy parts, including a die-casting machine body 1. The die-casting machine body 1 has four guide rails 2 inside. A fixed mold 3 is fixedly mounted on the outer wall of the guide rails 2, and a moving mold 4 is slidably mounted on the outer wall of the guide rails 2. An ejection hole 5 is symmetrically opened through one side of the fixed mold 3, and an ejection shell 6 is slidably installed on the inner wall of the ejection hole 5. A drive push rod 10 is fixedly mounted on one side of the moving mold 4, and an injection tube 11 is fixedly mounted on one side of the fixed mold 3.

[0032] In this embodiment, when the device is used, the moving mold 4 is first moved towards the fixed mold 3 by the drive push rod 10 to close the mold. After the mold is closed, molten aluminum is poured into the injection tube 11. Then, the molten aluminum is injected into the mold cavity inside the die-casting mold in a high-temperature, high-pressure and rapid manner by high-speed pushing. Then, the aluminum alloy solution in the mold cavity is allowed to cool and solidify. After solidification, the moving mold 4 is separated and demolded by the drive push rod 10.

[0033] Furthermore, pre-loosening vibration mold components 7 are provided on both sides of the moving mold 4. The pre-loosening vibration mold components 7 include a connecting rod 701 fixedly connected to one side of the moving mold 4, and a drive frame 702 fixedly connected to the other side wall of the connecting rod 701. During the demolding process, the drive frame 702 intermittently impacts and loosens the ejector shell 6 through the intermittent vibration component.

[0034] Specifically, when the moving mold 4 separates and moves, a connecting rod 701 is fixedly connected to one side of the moving mold 4, and a drive frame 702 is fixedly connected to the other side wall of the connecting rod 701. During the demolding process, the drive frame 702 intermittently impacts and loosens the ejector shell 6 through the intermittent vibration component. Thus, in the first half of the demolding, intermittent vibration is applied to the ejector shell 6 in the fixed mold 3. This vibration acts on the bottom of the workpiece that has not yet been demolded, realizing a two-stage demolding method of loosening first and then ejecting. In the first half, the movement of the moving mold 4 drives the intermittent vibration component, causing the ejector shell 6 to vibrate and push the workpiece with small amplitude and intermittent vibration, destroying the static friction and micro-adhesion points between the workpiece and the mold cavity, thereby avoiding local tearing of thin-walled or complex structural parts. In the second half, the ejection mechanism begins to eject formally. At this time, the workpiece has been initially loosened and can be ejected smoothly with a smaller force, thus ensuring the die-casting quality of this device.

[0035] Furthermore, the intermittent vibration component includes:

[0036] A mounting cylinder 703 is fixedly installed on one side of the fixed mold 3. A rotating rod 704 is slidably connected to the inner wall of the mounting cylinder 703, and a spiral groove 705 is opened on the outer wall of the rotating rod 704. A rotating rod 706 is rotatably connected to the rear end face of the ejector shell 6. A transmission belt assembly 707 is installed between the rotating rod 704 and the rotating rod 706. A connecting plate 708 is fixedly and rotatably installed at the same end of the rotating rod 704 and the rotating rod 706. The drive frame 702 is driven by the rotating rod 704 through the spiral groove 705.

[0037] Specifically, when the drive frame 702 moves, it slides along the outer wall of the first rotating rod 704. A spiral groove 705 is provided on the outer wall of the first rotating rod 704. The rear end face of the ejector shell 6 is rotatably connected to the second rotating rod 706. A transmission belt assembly 707 is installed between the first rotating rod 704 and the second rotating rod 706. A connecting plate 708 is fixedly and rotatably installed at the same end of the first rotating rod 704 and the second rotating rod 706. The drive frame 702 is driven by the spiral groove 705 and the first rotating rod 704. When the drive frame 702 moves, it can drive the first rotating rod 704 to rotate through the cooperation of the protrusions in the drive frame 702 and the spiral groove 705. Then, when the first rotating rod 704 rotates, it can synchronously drive the second rotating rod 706 to rotate through the transmission belt assembly 707.

[0038] Furthermore, a movable ring 709 is slidably connected to the outer wall of the rotating rod 706. A spring 710 is fixedly connected at equal intervals to one end face of the movable ring 709 facing the ejector shell 6, and a vibrating ring 711 is fixedly connected to the other end face of the spring 710. A circulation groove 712 is opened on the outer wall of the rotating rod 706 corresponding to the movable ring 709, and the movable ring 709 is driven by the rotating rod 706 through the circulation groove 712. A limiting rod 713 is fixedly connected at equal intervals to one end face of the ejector shell 6 facing the movable ring 709. The inner walls of the movable ring 709 and the vibrating ring 711 are slidably connected to the outer wall of the limiting rod 713, respectively.

[0039] Specifically, when the rotating rod 706 rotates, the moving ring 709 is driven by the rotating rod 706 through the circulation groove 712. The ejector shell 6 is fixedly connected to the end face of the moving ring 709 at equal distances. The inner walls of the moving ring 709 and the vibration ring 711 are slidably connected to the outer wall of the limiting rod 713, so that the moving ring 709 can move back and forth through the cooperation of the protrusion in the moving ring 709 and the circulation groove 712. The spring 710 is fixedly connected to the end face of the moving ring 709 at equal distances, and the vibration ring 711 is fixedly connected to the other end of the spring 710, so that the ejector shell 6 in the fixed mold 3 is subjected to intermittent vibration.

[0040] In embodiment two, based on the above embodiment, the ejector shell 6 is provided with an ejector lubrication component 8. The ejector lubrication component 8 includes a liquid storage cavity 801 opened inside the ejector shell 6. A pusher plate 802 is slidably connected inside the liquid storage cavity 801. During the demolding process, the drive frame 702 drives the pusher plate 802 through the extrusion and pushing component to continuously send the demolding liquid in the liquid storage cavity 801 into the space between the workpiece and the mold cavity for lubrication.

[0041] Furthermore, the squeeze push component includes:

[0042] A slide rod 803 is fixedly connected to the side of the push plate 802 facing the drive frame 702. The other ends of the two slide rods 803 extend through the inside of the ejector shell 6 to the outside. A connecting ring 804 is fixedly connected to the extended end of the slide rod 803. A spring 805 is fitted to the outer wall of the extended end of the slide rod 803. One end of the spring 805 is fixedly connected to the outer wall of one side of the ejector shell 6, and the other end of the spring 805 is fixedly connected to one end face of the connecting ring 804. Through holes 806 are opened at equal intervals on the front outer wall of the ejector shell 6.

[0043] The outer wall of the rotating rod 704 is provided with a linear guide groove 714, and the inner wall of the linear guide groove 714 is connected and matched with the inner wall of the spiral groove 705. The inner wall of the mounting cylinder 703 is fixedly connected with a spring 715, and the other end of the spring 715 is fitted and assembled with one end face of the rotating rod 704.

[0044] In this embodiment, during the first half of demolding, the storage cavity 801 is filled with demolding fluid. At the end of the first half, when the drive frame 702 contacts the connecting ring 804, the demolding fluid in the storage cavity 801 is squeezed by the push plate 802. At this time, the through hole 806 of the ejector shell 6 has not yet entered the mold cavity; that is, the through hole 806 of the ejector shell 6 is still covered by the ejector hole 5. This allows the push plate 802 to push the ejector shell 6, causing it to demold the workpiece within the mold cavity. When the workpiece has moved a certain distance, i.e., when the through hole 806 is exposed within the mold cavity, the push plate 802 will first... The release fluid in the storage chamber 801 is squeezed out through the through hole 806 to fill the gap between the workpiece and the mold cavity. During the entire ejection stroke, the extrusion and pushing component will be continuously extruded, and fresh release fluid will be continuously replenished to the moving interface. The state of ejection and fluid addition will always be maintained. Thus, during the ejection process, the liquid acts as a lubricant to reduce friction and reduce sliding damage between the workpiece and the mold cavity during the demolding process. On the other hand, it acts as a flexible force transmission medium to evenly distribute the ejection force on the ejection contact surface of the workpiece, avoiding local stress concentration, thereby ensuring the die casting quality of this device.

[0045] Specifically, during the latter half of demolding, the inner wall of the linear guide groove 714 is connected and matched with the inner wall of the spiral groove 705. The inner wall of the mounting cylinder 703 is fixedly connected with a second spring 715. The other end of the second spring 715 is fitted and assembled with one end face of the first rotating rod 704, so that the protrusion of the drive frame 702 will slide into the linear guide groove 714 to avoid continued vibration and change in ejection force. At the same time, the first rotating rod 704 can be retracted through the mounting cylinder 703 to match the movement of the second rotating rod 706. In addition, during subsequent mold closing, the third spring 805 can drive the push plate 802 to reset.

[0046] In embodiment three, based on the above embodiments, a demolding separation component 9 is provided inside the ejector shell 6. The demolding separation component 9 includes a demolding disc 901 rotatably connected to the ejector end face of the ejector shell 6. A connecting cylinder 902 is fixedly connected to the rear end face of the demolding disc 901, and a sliding column 903 is slidably connected to the inner wall of the connecting cylinder 902. A spring 904 is fixedly connected to the rear end face of the sliding column 903. After leaving the mold cavity, the push plate 802 drives the demolding disc 901 to rotate through the pressing and rotating assembly, so that the workpiece is separated from the ejector shell 6.

[0047] Furthermore, the crimping rotary assembly includes:

[0048] A clamping plate 905 is fixedly connected to one end of the sliding column 903 facing the liquid pusher plate 802. One end of the spring 904 is fixedly connected to the inner wall of the connecting cylinder 902. A fixing rod 906 is symmetrically fixedly connected to the outer wall of the sliding column 903. An inclined groove 907 is symmetrically opened on the outer wall of the connecting cylinder 902 corresponding to the fixing rod 906.

[0049] The side of the ejector plate 802 facing the demolding disc 901 has a slot 908 corresponding to the card plate 905, and the shape of the card plate 905 matches and fits the inner wall of the slot 908. Positioning blocks 909 are fixedly connected to both sides of the rear end of the ejector shell 6.

[0050] In this embodiment, when the ejector shell 6 moves to its maximum stroke, positioning blocks 909 are fixedly connected to both sides of the rear end of the ejector shell 6, thereby limiting the movement distance of the ejector shell 6. At this time, the push plate 802 can continue to move. A slot 908 is provided on the side of the push plate 802 facing the demolding disc 901 corresponding to the card plate 905, and the shape of the card plate 905 matches and fits the inner wall of the slot 908, so that the card plate 905 will be locked into the slot 908 to restrict its rotation, so that the push plate 802 drives the card plate 905 to move linearly. At this time, a connecting cylinder 902 is fixedly connected to the rear end face of the demolding disc 901, and the inner wall of the connecting cylinder 902 is... A sliding column 903 is slidably connected to the wall, and a spring 904 is fixedly connected to the rear end face of the sliding column 903. A fixing rod 906 is symmetrically fixedly connected to the outer wall of the sliding column 903. An inclined groove 907 is symmetrically opened on the outer wall of the connecting cylinder 902 corresponding to the fixing rod 906, so that the clamping plate 905 can be pulled forward and moved towards the demolding plate 901. Then, through the cooperation of the protrusion of the fixing rod 906 and the inclined groove 907, the demolding plate 901 is rotated. The rotation of the demolding plate 901 causes the contact surface between the workpiece and the ejector shell 6 to rotate relative to each other, thereby forcibly separating the workpiece from the ejector shell 6, so that the workpiece is separated and falls, making it easy for workers or robots to pick up, and ensuring reliable part removal.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
