[0001] This invention relates to the field of non-ferrous metal casting technology, and in particular to a die-casting equipment for nickel-based alloy forgings. Background Technology

[0002] With the rapid growth in demand for high-performance nickel-based alloy components from fields such as aerospace and new energy vehicles, traditional die-casting technology is facing unprecedented challenges. Currently, most die-casting equipment on the market relies on single-plunger linear die-casting, injecting molten metal into the mold cavity under high pressure of 100 to 200 MPa, and completing solidification through a conventional cooling system.

[0003] Existing technologies face the challenge of achieving both ultra-high pressure and ultra-high speed shearing simultaneously with a single plunger design, thus failing to effectively control the microstructure of the melt.

[0034] 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.

[0035] Example 1: As Figures 1 to 12As shown, this invention proposes a nickel-based alloy forging die-casting equipment, including a die-casting equipment body 1. The die-casting equipment body 1 includes a die-casting mold 2, a die-casting mechanism 3, and a linear propulsion mechanism 4. The die-casting mold 2 includes a flow channel component 21. The die-casting mechanism 3 includes a support 31, and a die-casting mechanism 34 is disposed within the support 31. The die-casting mechanism 34 includes a push rod 32, which is fixedly connected to the linear propulsion mechanism 4. The linear propulsion mechanism 4 drives the die-casting mechanism 34 to perform linear motion through the push rod 32. The die-casting mechanism 34 includes an outer plunger 341 and a planetary gear drive mechanism. An inner plunger 342 is provided, and an inner plunger 343 is provided inside the inner plunger 342. A planetary gear drive mechanism is used to drive the inner plunger 342 to rotate out from the outer plunger 341 and the inner plunger 343 to rotate out from the inner plunger 342. The planetary gear drive mechanism includes a planetary gear 347, which includes a planet carrier 3471 and a sun gear. The sun gear is driven by the inner plunger 343, and the planet carrier 3471 is driven by the inner plunger 342. The inner plunger 342 has a flow channel 3421, and the inner plunger 343 has a flow channel 3431. A connecting block 345 is provided on one side of the rotary drive mechanism 344. The connecting block 345 is fixedly connected to the outer plunger 341 and is used to fixally connect to the push rod 32.

[0036] Specifically, when the linear propulsion mechanism 4 is activated, it drives the push rod 32 and its connected outer plunger 341 to move linearly, pushing the molten metal towards the flow channel component 21. Simultaneously, the planetary gear drive mechanism begins operation. The sun gear is driven by the inner plunger 343, causing it to rotate and extend from within the middle plunger 342. The planetary carrier 3471 is driven by the middle plunger 342, allowing it to rotate and extend from within the middle plunger 342. This design allows the inner and outer plungers to inject molten metal into the flow channel component 21 at different speeds and pressures at different stages, achieving gradient pressurization and shear rate control, thereby optimizing the melt flow and solidification process. The multi-stage plunger structure achieved through the planetary gear drive mechanism allows for flexible adjustment of pressure and shear rate at each stage without increasing system complexity, greatly improving the uniformity and density of the melt microstructure and reducing defects such as porosity and cracks.

[0037] The middle plunger 342 is threadedly connected to the outer plunger 341. A transmission rod 348 is fitted inside the middle plunger 342 and is slidably connected to the middle plunger 342. One end of the transmission rod 348 is fixedly connected to the planetary carrier 3471. The transmission rod 348 includes a one-way rotating block 3481, which is unidirectionally rotatably connected to the transmission rod 348. A ratchet 3483 is provided on one side of the one-way rotating block 3481, and stop blocks 3482 are provided on both sides of the ratchet 3483. The stop blocks 3482 are located at one end of the transmission rod 348 and are hinged to the transmission rod 348. A torsion spring is provided at the hinge of the stop blocks 3482. When the planetary gear drive mechanism is activated, the planet carrier 3471 drives the transmission rod 348 to rotate. Since the one-way rotating block 3481 and the transmission rod 348 are connected in one direction, and the one-way rotating block 3481 has a ratchet 3483 on one side and stops 3482 on both sides, the one-way rotating block 3481 can only rotate freely in one direction, while the other direction is blocked by the stops 3482. The stops 3482 are hinged to one end of the transmission rod 348, and a torsion spring is provided at the hinge point, ensuring that the one-way rotating block 3481 can rotate flexibly or lock under specific conditions. Since the middle plunger 342 is threadedly connected to the outer plunger 341, when the transmission rod 348 drives the middle plunger 342 to rotate, the middle plunger 342 will extend or retract from the outer plunger 341 along the thread. During this period, the transmission rod 348 will not move with the middle plunger 342. When the middle plunger 342 extends, when one end of the middle plunger 342 moves to the one-way rotating block 3481, since the rotation direction of the transmission rod 348 is opposite to the meshing direction of the one-way rotating block 3481, the transmission rod 348 will not drive the one-way rotating block 3481 to rotate, thus stopping the movement of the middle plunger 342. When reverse operation is required, the transmission rod 348 reverses, and at this time the one-way rotating block 3481 can follow the rotation of the transmission rod 348, allowing the middle plunger 342 to perform corresponding extension and retraction according to the rotation direction of the transmission rod 348.

[0038] An inner rod 349 is fitted inside the transmission rod 348, and the inner rod 349 is rotatably connected to the transmission rod 348. One end of the inner rod 349 is fixedly connected to the sun gear of the planetary gear 347. An end-face ratchet shaft 3491 is provided at one end of the inner rod 349. A connecting rod 3432 is fitted outside the inner rod 349, and the connecting rod 3432 is slidably connected to the inner rod 349. A second end-face ratchet 34323 is installed at one end of the inner cavity of the connecting rod 3432, and a first end-face ratchet 34322 is installed at the other end of the inner cavity of the connecting rod 3432. The tooth direction of the first end-face ratchet 34322 is opposite to the tooth direction of the second end-face ratchet 34323. The end-face ratchet shaft 3491 encloses... The device includes a third end face ratchet 34911, which is located between the first end face ratchet 34322 and the second end face ratchet 34323. The teeth of the first end face ratchet 34322 and the second end face ratchet 34323 both mesh with the teeth of the third end face ratchet 34911. The connecting rod 3432 is provided with a retaining ring 34321, which engages with the middle plunger 342. The inner plunger 343 is sleeved on the outside of the connecting rod 3432. The side wall of the connecting rod 3432 is provided with a retaining strip 34324. The inner wall of the inner plunger 343 is provided with a groove 3433 that engages with the retaining strip 34324. The inner plunger 343 is threadedly connected to the middle plunger 342. In the specific implementation process, the movement of the middle plunger 342 will drive the movement of the inner plunger 343 and the connecting rod 3432. When the middle plunger 342 extends, the connecting rod 3432 moves, and finally the second end face ratchet 34323 of the connecting rod 3432 contacts the end face ratchet shaft 3491. The rotation of the inner rod 349 will be transmitted to the connecting rod 3432 through the end face ratchet shaft 3491 and the second end face ratchet 34323. The connecting rod 3432 drives the inner plunger 343 to rotate. Since the inner plunger 343 is threadedly connected to the middle plunger 342, the inner plunger 343 will extend out of the middle plunger 342 along the thread when rotating. When the middle plunger 342 retracts to the outer plunger 341, the connecting rod 3432 moves, and finally the second end face ratchet 34323 of the connecting rod 3432 contacts and engages with the end face ratchet shaft 3491. The rotation of the inner rod 349 is transmitted to the connecting rod 3432 through the end face ratchet shaft 3491 and the second end face ratchet 34323. The connecting rod 3432 drives the inner plunger 343 to rotate, and the inner plunger 343 retracts to the middle plunger 342 along the thread when rotating. The rotational speed of the planetary carrier 3471 is different from that of the sun gear; the middle plunger 342 rotates slowly, while the inner plunger 343 rotates quickly. This not only enhances the flexibility and controllability of equipment operation, but also effectively improves the matching degree of pressure and shear rate during melt injection, thereby optimizing the microstructure of nickel-based alloys and reducing defects such as porosity and cracks. Furthermore, by using different speed ratios between the planetary carrier 3471 and the sun gear, the rotational speeds of the middle plunger 342 and the inner plunger 343 can be achieved, thereby further improving the efficiency and quality of material processing.

[0039] The end-face ratchet shaft 3491 includes a connecting shaft 34912, which is fixedly connected to the third end-face ratchet 34911. One end of the connecting shaft 34912 passes through the first end-face ratchet 34322 and is located inside the inner rod 349. A spring 34913 is fixedly connected to one end of the connecting shaft 34912, and one end of the spring 34913 is fixedly connected to the inner rod 349. The inner wall of the inner rod 349 has a groove 3492, and the connecting shaft 34912 has a protrusion that engages with the groove 3492. Through the cooperation of the protrusion and the groove 3492, the rotation of the inner rod 349 can drive the end-face ratchet shaft 3491 to rotate. When the connecting rod 3432 moves, the elasticity of the spring 34913 allows the third end-face ratchet 34911 to dynamically adjust its position to meet the meshing requirements of the first end-face ratchet 34322 or the second end-face ratchet 34323. In addition, the presence of spring 34913 can also buffer the impact caused by changes in motion, extending the service life of the equipment.

[0040] A slide rod 346 is fixedly connected to the side wall of the outer plunger 341. The slide rod 346 is provided with a mating part 3461. A slide rail 33 is fixedly connected to the support 31. The slide rail 33 is provided with a docking part 331, which engages with the mating part 3461. The mating part 3461 is a locking block, and the docking part 331 is a locking groove, which engages with the locking block. When the outer plunger 341 moves linearly during the die-casting process, the slide rod 346 engages with the locking block on it and the locking groove on the slide rail 33, forming a stable sliding guide structure. This design ensures that the outer plunger 341 always maintains a precise linear trajectory during movement, avoiding problems such as uneven pressure distribution or unstable melt injection caused by deviation or shaking.

[0041] A rotary drive mechanism 344 is mounted on one end of the outer plunger 341. The rotary drive mechanism 344 provides power to drive the sun gear of the planetary gear 347. The rotary drive mechanism 344 is a hydraulic motor. When the equipment is running, the hydraulic system drives the hydraulic motor to rotate by supplying high-pressure hydraulic oil. The output shaft of the hydraulic motor is directly connected to the sun gear of the planetary gear system. With the start of the hydraulic motor, it drives the sun gear to rotate, thereby driving the entire planetary gear system. This design allows the inner rod 349, the middle plunger 342, and the inner plunger 343 to rotate precisely at a predetermined speed ratio, thereby achieving fine control of the pressure and shear rate during the melt injection process.

[0042] The flow channel component 21 includes an outer plunger sleeve 211, a middle plunger sleeve 212, and an inner plunger sleeve 213. The inner diameter of the outer plunger sleeve 211 is the same as the diameter of the outer plunger 341, the inner diameter of the middle plunger sleeve 212 is the same as the diameter of the middle plunger flow channel 3421, and the inner diameter of the inner plunger sleeve 213 is the same as the diameter of the inner plunger 343. The inner diameter of the outer plunger sleeve 211 matches that of the outer plunger 341, ensuring that the outer plunger can move smoothly and accurately during linear advancement, avoiding any deviation or shaking. When the middle plunger 342 extends from the middle plunger flow channel 3421, the inner diameter of the middle plunger sleeve 212 matches that of the middle plunger flow channel 3421, ensuring that the molten metal can pass smoothly and enter the mold cavity, while providing necessary guiding and sealing functions. Similarly, the inner diameter of the inner plunger sleeve 213 matches that of the inner plunger 343, ensuring that the inner plunger maintains a high-precision movement trajectory during the final injection stage, preventing leakage or overflow.

[0043] The lead angle of the middle plunger channel 3421 is 15 degrees, and the lead angle of the inner plunger channel 3431 is 45 degrees. The smaller lead angle of the middle plunger channel 3421 (15 degrees) means that the molten metal experiences a gentler spiral path as it passes through the channel. This helps achieve stable fluid delivery and pressure accumulation at relatively low speeds, making it suitable for initial filling of the mold cavity, ensuring uniform melt distribution, and reducing the risk of porosity. The larger lead angle of the inner plunger channel 3431 (45 degrees) causes the molten metal to pass through the channel at a faster speed and higher shear rate. This is suitable for stages requiring rapid and high-pressure injection, providing stronger filling force and finer microstructure control, helping to eliminate cold shuts and improve the density of the final product. By rationally setting the lead angles of the middle plunger channel 3421 and the inner plunger channel 3431, the flow rate and pressure distribution of the molten metal at different stages can be effectively controlled, ensuring uniform material filling of the mold cavity and reducing defects such as porosity and cold shuts. A smaller lead angle facilitates the smooth introduction of the melt and avoids oxide inclusions caused by turbulence; a larger lead angle provides a high shear rate, promotes grain refinement, improves the microstructure of the material, and enhances the mechanical properties of the final product.

[0044] Specifically, the working principle of this invention is as follows:

[0045] When the linear propulsion mechanism 4 is activated, it drives the outer plunger 341 to move linearly via the push rod 32, pushing the molten metal towards the flow channel component 21. Simultaneously, the rotary drive mechanism 344 (hydraulic motor) is activated, driving the sun gear in the planetary gear system to rotate. This, in turn, drives the middle plunger 342 and the inner plunger 343 to rotate at a predetermined speed ratio via the planet carrier 3471. Specifically, the sun gear is fixedly connected to the inner rod 349, which transmits power to the connecting rod 3432 via the end face ratchet shaft 3491 and the first and second end face ratchet wheels 34322 and 34323, ultimately causing the inner plunger 343 to extend or retract from inside the middle plunger 342. This multi-stage plunger design allows for the injection of molten metal into the flow channel component 21 at different speeds and pressures at different stages, achieving gradient pressurization and shear rate control, and optimizing the melt flow and solidification process.

[0046] The transmission rod 348 is connected to the planetary gear system via the planetary carrier 3471. The one-way rotating block 3481 and the ratchet 3483 ensure that the transmission rod 348 can rotate freely in one direction and be blocked in the other, thereby controlling the extension and retraction of the middle plunger 342. When the middle plunger 342 is threadedly connected to the outer plunger 341 and rotates, the transmission rod 348 will not move accordingly, allowing the middle plunger 342 to extend or retract from the outer plunger 341 along the thread. In addition, the spring 34913 in the inner rod 349 provides preload to ensure that the third end face ratchet 34911 is always engaged with the first end face ratchet 34322 and the second end face ratchet 34323.

[0047] The central plunger channel 3421 and the inner plunger channel 3431 are designed with lead angles of 15 degrees and 45 degrees, respectively. This design allows the molten metal to follow different spiral paths as it passes through the channels. The central plunger channel 3421, with its smaller lead angle, helps achieve stable fluid delivery and pressure accumulation at lower speeds, making it suitable for initial filling of the mold cavity and reducing the risk of porosity. The inner plunger channel 3431, with its larger lead angle, is suitable for rapid and high-pressure injection stages, providing stronger filling force and higher shear rate, promoting grain refinement, improving the material's microstructure, and increasing the density and mechanical properties of the final product. This segmented channel design effectively controls the flow characteristics and pressure distribution of the melt at different stages, ensuring uniform material filling of the mold cavity and reducing defects.

[0048] In summary, this invention solves the problem that traditional nickel-based alloy forging die-casting equipment is insufficient in achieving ultra-high pressure and ultra-high speed shearing, thus failing to effectively control the microstructure of the melt.
