Description

Technical Field

[0001] This invention belongs to the technical field of die casting equipment, and in particular relates to an extrusion casting equipment for aluminum-magnesium alloy filling. Background Technology

[0002] Aluminum-magnesium alloys are lightweight alloy materials formed by adding magnesium to aluminum as the base material. They have advantages such as low density, high specific strength, and good corrosion resistance. The addition of magnesium improves the strength and stiffness of the alloy while maintaining a low density, making it highly advantageous in weight-reduction applications. Aluminum-magnesium alloy filling and extrusion casting equipment is an integrated molding device that injects molten aluminum-magnesium alloy into a mold under high pressure and performs extrusion and shrinkage compensation. The equipment consists of a melting and holding furnace, an injection system, a mold closing mechanism, and a control system, enabling a production process with fast filling speed, sufficient shrinkage compensation, and a dense microstructure.

[0003] A Chinese patent application (or patent) with publication number CN223097970U discloses an extrusion casting device for aluminum-magnesium alloy filling, including a punch, an operating table, a die, a furnace, and an injection assembly. A support frame is provided on the operating table, and a first hydraulic cylinder is provided on the support frame. The punch is provided on the hydraulic rod of the first hydraulic cylinder. A feeding chamber is provided on the operating table, and the die is provided on the operating table with a feed hole at its lower end. The furnace is provided on the operating table with a discharge hole at its lower end. The injection assembly is provided inside the feeding chamber.

[0004] However, the above-mentioned device still has the following problems during implementation: In the die casting process of aluminum-magnesium alloys, molten metal is propelled by a hydraulic cylinder and injected at high speed into the mold cavity through the gating system. However, the mold temperature is relatively low. When the high-temperature melt comes into contact with the low-temperature mold wall, the surface layer cools rapidly or even solidifies, forming a hard shell. This not only hinders the smooth flow of molten metal but also easily leads to defects such as cold shuts, flow marks, and internal shrinkage cavities on the casting surface, seriously affecting the uniformity of molding and the quality of the finished product.

[0005] To address this issue, we provide an extrusion casting apparatus for aluminum-magnesium alloy filling, which solves the aforementioned problems. Summary of the Invention

[0033] Example 1 Please see Figures 1-10This invention relates to an extrusion casting device for aluminum-magnesium alloy filling, comprising a base 1, a support shell 2 mounted on top of the base 1, an adjusting shell 3 disposed inside the support shell 2, a bottom mold 4 connected to one side of the adjusting shell 3, and a top mold 5 disposed to one side of the bottom mold 4; an adjusting assembly 6 disposed on one side of the base 1, the adjusting assembly 6 including a feed pipe 601 connected to one side of the adjusting shell 3, a molten injection groove 602 opened inside the adjusting shell 3, a first hydraulic rod 603 mounted on the top of the adjusting shell 3, a second hydraulic rod 604 mounted on the bottom of the adjusting shell 3, and a first adjusting plug 605 and a second adjusting plug 606 slidably connected inside the molten injection groove 602, wherein a fixed amount of molten metal is injected into the bottom mold 4 through the adjusting assembly 6. A preheating assembly 7 is provided on one side of the adjusting shell 3. The preheating assembly 7 includes a drive motor 701 installed on one side of the adjusting shell 3, a square rod 702 installed on the output end of the drive motor 701, a preheating plate 703 installed on one side of the square rod 702, and a heater 704 installed inside the preheating plate 703.

The second hydraulic rod 604 is installed on the bottom of the regulating shell 3, driving the second regulating plug 606 to adjust the volume of the injection tank 602, achieving precise volume control. The first regulating plug 605 slides within the injection tank 602, pushing the molten metal into the mold. To prevent backflow, the second adjusting plug 606 slides within the injection tank 602, changing the effective volume to adjust the amount of melt per injection. The drive motor 701 is installed on one side of the adjusting shell 3, driving the square rod 702 to rotate, causing the preheating plate 703 to be automatically positioned. The square rod 702 transmits torque and allows the moving sleeve 11 to slide, ensuring the stable rotation and movement of the preheating plate 703. The preheating plate 703 rotates between the molds, and the mold is uniformly preheated by the internal heater 704, improving the fluidity of the melt. The heater 704 is installed inside the preheating plate 703, and after electric heating, it transfers heat to achieve rapid and uniform preheating. The ejector pin 801 slides within the bottom mold 4, directly pushing the casting to avoid surface damage. The adjusting plate 802 connects the ejector pin 801 and the adjusting shaft 803, transmitting the ejection force and distributing it evenly. The adjusting shaft 803 slides within the adjusting groove 804, converting the rotational motion into linear motion, driving the ejector pin 801 to move.

[0035] Example 2 Please see Figures 1-10 Based on Embodiment 1, the ejection assembly 8 further includes a support shaft 805 installed on both sides of the adjusting shell 3, a first gear 806 installed on the surface of the support shaft 805, a servo motor 807 installed on one side of the supporting shell 2, and a second gear 808 installed at the output end of the servo motor 807. The first gear 806 meshes with the second gear 808 on one side. The surface of the support shaft 805 is movably connected to the inner wall of the supporting shell 2 through a bearing. The adjusting shaft 803 is slidably connected to the inner wall of the adjusting groove 804. A support frame 9 is fixedly connected to one side of the adjusting shell 3. A third hydraulic rod 10 is fixedly connected to one side of the support frame 9. The output end of the third hydraulic rod 10 is fixedly connected to the top mold 5. A movable sleeve 11 is slidably connected to the surface of the square rod 702. A rotating plate 12 is fixedly connected to one side of the movable sleeve 11. The other side of the rotating plate 12 is fixedly connected to the preheating plate 703.

[0036] Specifically: An adjustment groove 804 is formed inside the support shell 2, guiding the trajectory of the adjustment shaft 803 to ensure smooth and reliable demolding. The support shaft 805 is installed on both sides of the adjustment shell 3, serving as a fulcrum for rotation, facilitating the rotation of the adjustment shell 3 to achieve ejection. The first gear 806 is installed on the surface of the support shaft 805, meshing with the second gear 808 to transmit power and drive the adjustment shell 3 to rotate. The servo motor 807 is installed on one side of the support shell 2, precisely controlling the rotation angle and driving the ejection assembly 8 to complete demolding. The second gear 808 is installed at the output end of the servo motor 807, smoothly transmitting power. The first gear 806 is fixed to one side of the adjusting shell 3, and the third hydraulic rod 10 is installed to ensure the stable movement of the top mold 5. The third hydraulic rod 10 is fixed on the support frame 9 to drive the top mold 5 to open and close, realizing the filling and demolding actions. The moving sleeve 11 slides on the surface of the square rod 702, connects to the rotating plate 12 and transmits the rotational torque. The rotating plate 12 connects the moving sleeve 11 and the preheating plate 703 to ensure the smooth rotation and movement of the preheating plate 703. The spring 13 is sleeved on the square rod 702 to provide pre-tightening force, so that the preheating plate 703 elastically fits the mold and avoids hard collision.

[0037] Example 3 Please see Figures 1-10 Based on Embodiments 1 and 2, a spring 13 is sleeved on the surface of the square rod 702. One end of the spring 13 is fixedly connected to the movable sleeve 11. A guide shell 14 is connected to one side of the feed pipe 601. An electric push rod 15 is movably connected to the top of the guide shell 14. An adjusting frame 16 is movably connected to the output end of the electric push rod 15. A sealing plate 17 is fixedly connected to the other end of the adjusting frame 16. The bottom of the sealing plate 17 is movably connected to the guide shell 14. The output end of the first hydraulic rod 603 is fixedly connected to the first adjusting plug 605. The output end of the second hydraulic rod 604 is fixedly connected to the second adjusting plug 606. A slider 18 is fixedly connected to the bottom of the adjusting plate 802. A horizontal plate 19 is slidably connected to the surface of the slider 18. One side of the horizontal plate 19 is fixedly connected to the adjusting shell 3. A sliding rod 20 is fixedly connected to one side of the top mold 5. A support plate 21 is slidably connected to the surface of the sliding rod 20. One side of the support plate 21 is fixedly connected to the support frame 9.

[0038] Specifically: The guide shell 14 is connected to the feed pipe 601, serving as a feeding port to guide the molten metal into the equipment. The electric push rod 15 is movably connected to the top of the guide shell 14, driving the adjusting frame 16 to control the opening and closing of the sealing plate 17. The adjusting frame 16 connects the electric push rod 15 and the sealing plate 17, causing the sealing plate 17 to rotate and open or close. The sealing plate 17 is movably connected to the bottom of the guide shell 14, preventing air from entering and molten metal from oxidizing when closed, ensuring pressure sealing. The slider 18 is fixed to the bottom of the adjusting plate 802 and slides on the horizontal plate 19, guiding the adjusting plate 802. The horizontal plate 19 is fixed to one side of the adjusting shell 3, serving as a guide rail for the slider 18 to improve ejection accuracy. The slide rod 20 is fixed to one side of the top mold 5 and slides inside the support plate 21 to prevent the top mold 5 from tilting. The support plate 21 is fixed on the support frame 9, guiding the slide rod 20 and enhancing the rigidity and repeatability of the top mold 5.

[0039] The working principle of this invention is as follows: The operator starts the servo motor 807 via an external controller. The servo motor 807 drives the second gear 808 to rotate. The second gear 808, in conjunction with the first gear 806, drives the support shaft 805 to rotate. The support shaft 805, in conjunction with the adjusting housing 3, drives the adjusting plate 802 to rotate 90 degrees. The adjusting plate 802 then drives the adjusting shaft 803 to slide within the adjusting groove 804. Figure 10 As shown, while the adjusting shaft 803 rotates, it drives the adjusting plate 802 and the ejector pin 801 to move, causing the ejector pin 801 to reset. Then, the drive motor 701 is started. The drive motor 701, together with the square rod 702, drives the preheating plate 703 to rotate, so that the rotating plate rotates between the bottom mold 4 and the top mold 5. Then, the third hydraulic rod 10 is started. The third hydraulic rod 10 drives the top mold 5 to move. The top mold 5 pushes the preheating plate 703 to fit into the bottom mold 4. Then, the heater 704 is started. The heater 704 preheats the bottom mold 4 and the top mold 5. After the preheating is completed, the third hydraulic rod 10 is controlled to drive the top mold 5 to reset. The drive motor 701 is controlled to drive the preheating plate 703 to reset. After the preheating plate 703 is reset, the top mold 5 and the bottom mold 4 are closed again.

[0040] The molten aluminum-magnesium alloy is then poured into the guide shell 14 and injected into the injection tank 602 through the feed pipe 601. The second hydraulic rod 604 is activated, which pushes the second adjusting plug 606 upward, thereby adjusting the amount of molten liquid injected into the injection tank 602. Then, the first hydraulic rod 603 is activated, which drives the first adjusting plug 605 downward. The amount of molten liquid between the first adjusting plug 605 and the second adjusting plug 606 is the amount of molten liquid required for a single casting.

[0041] Then, the first hydraulic rod 603 and the second hydraulic rod 604 are activated simultaneously, driving the first adjusting plug 605 and the second adjusting plug 606 to move downwards in sync. After the second adjusting plug 606 moves, the injection pipe between the adjusting shell 3 and the bottom mold 4 is exposed. The liquid is injected into the bottom mold 4 and the top mold 5 through the injection pipe. The first hydraulic rod 603 and the second hydraulic rod 604 are continuously controlled to pressurize the molten liquid and improve the tightness of the casting.

[0042] After the model cools down, the third hydraulic rod 10 is controlled to reset the top mold 5. Then, the servo motor 807 is started to rotate the adjusting shell 3 counterclockwise by 90 degrees. While the adjusting shell 3 is rotating, the adjusting shaft 803 slides inside the adjusting groove 804. The adjusting shaft 803 drives the adjusting plate 802 and the ejector pin 801 to move. When the ejector pin 801 moves, it pushes out the cooled mold, realizing automatic demolding and effectively improving the casting efficiency.

[0043] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
