DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] Example 1: Figures 1 to 12As shown, the present invention proposes a nickel-based alloy forging die-casting equipment, including a forging die-casting equipment body 1, the forging 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, a die-casting mechanism 34 is arranged in the support 31, the die-casting mechanism 34 includes a push rod 32, the push rod 32 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, a planetary gear drive mechanism, the outer plunger 341 The inner sleeve is provided with a middle plunger 342, and the inner sleeve of the middle plunger 342 is provided with an inner plunger 343. The planetary gear drive mechanism is used to drive the middle plunger 342 to rotate and extend from the outer plunger 341, and the inner plunger 343 to rotate and extend from the middle plunger 342. The planetary gear drive mechanism includes a planetary gear 347, which includes a planetary carrier 3471 and a sun gear. The sun gear is transmission-connected to the inner plunger 343, and the planetary carrier 3471 is transmission-connected to the middle plunger 342. The middle plunger 342 is provided with a middle plunger flow channel 3421, and the inner plunger 343 is provided with an inner plunger flow channel 3431. A connecting block 345 is provided on one side of the rotation drive mechanism 344. The connecting block 345 is fixedly connected to the outer plunger 341 and is used to be fixedly connected to the push rod 32.

[0036] Specifically, when the linear propulsion mechanism 4 is started, it drives the push rod 32 and the outer plunger 341 connected thereto to perform linear motion, pushing the molten metal toward the runner member 21. At the same time, the planetary gear drive mechanism begins to operate, and the sun gear is connected to the inner plunger 343, causing the inner plunger 343 to rotate and extend from the inside of the middle plunger 342; the planetary carrier 3471 is connected to the middle plunger 342, allowing the middle plunger 342 to rotate and extend from the inside of the middle plunger 342. This design allows the inner and outer plungers to inject molten metal into the runner member 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 by the planetary gear drive mechanism can flexibly adjust the pressure and shear rate of each stage without increasing the complexity of the system, greatly improving the uniformity and density of the melt microstructure, and reducing the occurrence of defects such as pores and cracks.

[0037] The middle plunger 342 is threadedly connected to the outer plunger 341, and a transmission rod 348 is provided inside the middle plunger 342. The transmission rod 348 is slidingly connected to the middle plunger 342, and one end of the transmission rod 348 is fixedly connected to the planetary frame 3471. The transmission rod 348 includes a one-way rotating block 3481, and the one-way rotating block 3481 is unidirectionally rotated with the transmission rod 348. A ratchet 3483 is provided on one side of the one-way rotating block 3481, and blocks 3482 are provided on both sides of the ratchet 3483. The block 3482 is provided at one end of the transmission rod 348, and the block 3482 is hinged to the transmission rod 348. A torsion spring is provided at the hinge of the block 3482. When the planetary gear drive mechanism is activated, planet carrier 3471 drives transmission rod 348 to rotate. Because one-way rotating block 3481 is connected to transmission rod 348 in a one-way rotational manner, and one-way rotating block 3481 is provided with a ratchet 3483 on one side and stops 3482 on both sides, one-way rotating block 3481 can rotate freely in only one direction, while the other direction is blocked by stops 3482. Stop 3482 is hinged to one end of transmission rod 348, and a torsion spring is provided at the hinge, ensuring that one-way rotating block 3481 can flexibly rotate or lock under specific conditions. Since the middle piston 342 is threadedly connected to the outer piston 341, when the transmission rod 348 drives the middle piston 342 to rotate, the middle piston 342 will extend or retract from the outer piston 341 along the thread. During this period, the transmission rod 348 will not move with the middle piston 342. When the middle piston 342 extends, one end of the middle piston 342 moves to the one-way rotating block 3481. Since the rotation direction of the transmission rod 348 is opposite to the engagement direction of the one-way rotating block 3481, the transmission rod 348 will not drive the one-way rotating block 3481 to rotate, thereby stopping the movement of the middle piston 342. When reverse operation is required, the transmission rod 348 is reversed. At this time, the one-way rotating block 3481 can follow the rotation of the transmission rod 348, allowing the middle piston 342 to perform corresponding telescopic movement according to the rotation direction of the transmission rod 348.

[0038] An inner rod 349 is sleeved 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. The inner rod 349 has an end ratchet shaft 3491 provided at one end of the inner rod 349. A connecting rod 3432 is sleeved outside the inner rod 349, and the connecting rod 3432 is slidably connected to the inner rod 349. A second end ratchet 34323 is installed at one end of the inner cavity of the connecting rod 3432, and a first end ratchet 34322 is installed at the other end of the inner cavity of the connecting rod 3432. The gear teeth direction of the first end ratchet 34322 is opposite to the gear teeth direction of the second end ratchet 34323. The end ratchet shaft 3491 includes The third end face ratchet 34911 is arranged 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 teeth of the second end face ratchet 34323 are engaged with the teeth of the third end face ratchet 34911. The connecting rod 3432 is provided with a snap ring 34321, and the snap ring 34321 is engaged 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 clamping strip 34324. The inner wall of the inner plunger 343 is provided with a groove 3433 engaged with the clamping strip 34324. The inner plunger 343 is threadedly connected to the middle plunger 342. During 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 from the middle plunger 342 along the thread when rotating. When the middle plunger 342 retracts the outer plunger 341, the connecting rod 3432 moves, and eventually 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 the middle plunger 342 along the thread when rotating. The rotation speed of the planet carrier 3471 is different from that of the sun gear. The middle plunger 342 rotates slowly, and 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 the melt injection process, thereby optimizing the microstructure of the nickel-based alloy and reducing defects such as pores and cracks. In addition, by using different speed ratios between the planet carrier 3471 and the sun gear, the middle plunger 342 can rotate slower and the inner plunger 343 can rotate faster, further improving the efficiency and quality of material processing.

[0039] The end ratchet shaft 3491 includes a connecting shaft 34912, which is fixedly connected to the third end ratchet 34911. One end of the connecting shaft 34912 passes through the first end ratchet 34322 and is disposed within 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. A slot 3492 is provided on the inner wall of the inner rod 349, and a protrusion is provided on the connecting shaft 34912 that engages with the slot 3492. The engagement of the protrusion with the slot 3492 allows the rotation of the inner rod 3491 to drive the end ratchet shaft 3491. When the connecting rod 3432 moves, the elastic action of the spring 34913 enables the third end ratchet 34911 to dynamically adjust its position to accommodate the engagement requirements of the first end ratchet 34322 or the second end ratchet 34323. In addition, the presence of spring 34913 can also buffer the impact caused by movement changes and extend the service life of the equipment.

[0040] The side wall of the outer plunger 341 is fixedly connected to a slide rod 346, which is provided with a mating portion 3461. The support 31 is fixedly connected to the slide rail 33, which is provided with a docking portion 331. The docking portion 331 is engaged with the mating portion 3461. The mating portion 3461 is a clamping block, and the docking portion 331 is a clamping slot. The clamping slot is engaged with the clamping block. When the outer plunger 341 performs linear motion during the die-casting process, the slide rod 346 is engaged with the clamping slot on the slide rail 33 through the clamping block on it, forming a stable sliding guide structure. This design ensures that the outer plunger 341 always maintains a precise straight line trajectory during movement, avoiding problems such as uneven pressure distribution or unstable melt injection caused by offset or shaking.

[0041] One end of the outer plunger 341 is equipped with a rotary drive mechanism 344, which is used to provide power for the sun gear drive of the planetary gear 347. Rotary drive mechanism 344 is a hydraulic motor. When the equipment is in operation, 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. As the hydraulic motor starts, 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 according to a predetermined speed ratio, thereby achieving fine control of the pressure and shear rate during the melt injection process.

[0042] The runner assembly 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 matches the diameter of the outer plunger 341, the inner diameter of the middle plunger sleeve 212 matches the diameter of the middle plunger runner 3421, and the inner diameter of the inner plunger sleeve 213 matches the diameter of the inner plunger 343. The inner diameter of the outer plunger sleeve 211 matches the inner diameter 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 runner 3421, the inner diameter of the middle plunger sleeve 212 matches the inner diameter of the middle plunger runner 3421, ensuring that the molten metal can pass smoothly and enter the mold cavity, while also providing the necessary guiding and sealing functions. Likewise, the inner diameter of the inner plunger sleeve 213 matches that of the inner plunger 343, ensuring that the inner plunger can maintain a high-precision motion trajectory even in the final injection stage, thereby preventing leakage or overflow.

[0043] The lead angle of the middle plunger runner 3421 is fifteen degrees, and the lead angle of the inner plunger runner 3431 is forty-five degrees. The smaller lead angle of the middle plunger runner 3421 (lead angle of 15 degrees) means that the molten metal will experience a relatively gentle spiral path when passing through the runner, which helps to achieve stable fluid delivery and pressure accumulation at relatively low speeds, suitable for initial filling of the mold cavity, ensuring uniform distribution of the melt and reducing the risk of pore formation. The larger lead angle of the inner plunger runner 3431 (lead angle of 45 degrees) causes the molten metal to pass through the runner at a faster speed and higher shear rate, which is suitable for stages requiring rapid and high-pressure injection. It can provide stronger filling force and more refined microstructure control capabilities, help eliminate cold shut phenomena and improve the density of the final product. By reasonably setting the lead angles of the middle plunger runner 3421 and the inner plunger runner 3431, the flow velocity and pressure distribution of the molten metal at different stages can be effectively controlled, ensuring that the material evenly fills the mold cavity and reducing the occurrence of defects such as pores and cold shuts. A smaller lead angle is conducive to the smooth introduction of the melt and avoids oxidation inclusions caused by turbulence; a larger lead angle can provide a high shear rate, promote grain refinement, improve the microstructure of the material, and enhance the mechanical properties of the final product.

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

[0045] When the linear propulsion mechanism 4 is started, it drives the outer plunger 341 to move linearly through the push rod 32, pushing the molten metal toward the runner component 21. At the same time, the rotary drive mechanism 344 (hydraulic motor) is started, driving the sun gear in the planetary gear system to rotate, and then driving the middle plunger 342 and the inner plunger 343 to rotate according to a predetermined speed ratio through the planetary carrier 3471. Specifically, the sun gear is fixedly connected to the inner rod 349, and the inner rod 349 transmits power to the connecting rod 3432 through the end face ratchet shaft 3491 and the first end face ratchet 34322 and the second end face ratchet 34323, ultimately causing the inner plunger 343 to extend or retract from the inside of the middle plunger 342. This multi-stage plunger design can inject molten metal into the runner 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 planet carrier 3471. A one-way rotating block 3481 and ratchet 3483 ensure that the transmission rod 348 can rotate freely in one direction while being 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 does not move with it, allowing the middle plunger 342 to extend or retract along the threads within the outer plunger 341. Furthermore, a spring 34913 within the inner rod 349 provides a preload, ensuring that the third end ratchet 34911 remains engaged with the first end ratchet 34322 and the second end ratchet 34323.

[0047] The middle plunger runner 3421 and the inner plunger runner 3431 are set with lead angles of 15 degrees and 45 degrees respectively. This design causes the molten metal to experience different spiral paths when passing through the runners. The middle plunger runner 3421 with a smaller lead angle helps to achieve stable fluid delivery and pressure accumulation at lower speeds, which is suitable for initial filling of the mold cavity and reduces the risk of pore formation; the inner plunger runner 3431 with a larger lead angle is suitable for the rapid and high-pressure injection stage, providing stronger filling force and higher shear rate, promoting grain refinement, improving the material microstructure, and enhancing the density and mechanical properties of the final product. Through this segmented runner design, the flow characteristics and pressure distribution of the melt at different stages can be effectively controlled, ensuring that the material evenly fills the mold cavity and reducing the occurrence of defects.

[0048] In summary, the present invention solves the problem that conventional nickel-based alloy forging die-casting equipment is insufficient in achieving ultra-high pressure and ultra-high speed shearing, and thus cannot effectively control the melt microstructure.
