Description

Technical Field

[0001] This invention relates to the field of die-casting equipment technology, specifically to an aluminum alloy die-casting equipment for the production of automotive parts. Background Technology

[0002] Die casting technology, as a highly efficient and precise metal forming process, is widely used in the automotive industry for the large-scale manufacturing of aluminum alloy housing parts, such as engine hoods, gearbox housings, and various structural brackets. This process, by injecting molten metal at high pressure and high speed into a mold cavity, can achieve the forming of parts with complex geometries, high dimensional accuracy, and good surface quality.

[0003] Chinese Patent No. CN118699322A discloses a die-casting equipment and method for die-casting aluminum alloy shells, including a die-casting mechanism. The die-casting mechanism includes a base frame, and a feeding mechanism is installed inside the base frame. The feeding mechanism includes a limiting frame and a mounting frame. This device, through the arrangement of an L-shaped connecting plate and side plates, restricts the aluminum alloy shell during feeding. Furthermore, the airflow slows the falling speed of the aluminum alloy shell, reducing the impact of the falling shell and preventing collisions. Simultaneously, the airflow continues to cool the aluminum alloy shell, ensuring a high production yield. Through the cooperation of an inclined plate and a second hydraulic cylinder, the aluminum alloy shell is slowly moved along the inclined surface into a placing tray, facilitating the collection of the formed aluminum alloy shell. This method does not cause wear on the aluminum alloy shell, ensuring a high production yield.

[0004] To improve the output efficiency of a single die-casting cycle and reduce the cost per unit, modern die-casting production generally adopts a multi-cavity mold design. This design allows for the simultaneous forming of several identical parts in multiple cavities within the same die, significantly increasing production capacity. However, this efficient production method also brings inherent post-processing challenges: during die casting, the molten metal not only fills the part cavities but also the runner system connecting the cavities (including the main runner, branch runners, and gates), resulting in a finished product after demolding that is an integrated casting of multiple parts connected by solidification runners. The currently common post-processing method is as follows: after the die-casting equipment completes mold opening, a robot or operator removes the integral continuous casting and transfers it to a separate post-processing station. At this station, manual positioning of the casting onto equipment such as a punch press, hydraulic shears, or sawing machine is required. After manual alignment, a cutting operation is performed to separate the individual parts and obtain individual finished products. This process not only involves a large amount of manual intervention, which limits production efficiency, but also introduces quality fluctuations due to factors such as operator skill, focus, and fatigue. This can easily lead to uneven cutting edges, out-of-tolerance critical dimensions, or mechanical damage to the surface of parts, seriously affecting product quality consistency. In addition, the runners generated during cutting need to be collected, sorted, and transported to the smelting process for reuse, further increasing the complexity of material handling and production costs.

[0015] The advantages of this invention compared to the prior art are: 1.

[0016] 2. In the slitting process, the inclined guide surface at the bottom of the limiting slitting seat allows the waste generated during slitting to slide along the inclined guide surface towards the outlet of the diversion mounting frame under the action of gravity, achieving automatic classification and conveying of waste. After slitting, the waste is conveyed to the designated waste processing area via the limiting slitting seat and the diversion mounting frame, eliminating the need for manual collection, sorting, and transfer, significantly reducing the complexity of material handling. Simultaneously, this waste can be transferred to the smelting process for reuse, improving resource utilization, reducing raw material waste, further reducing production costs, and enhancing the economic efficiency of the entire production process.

[0028] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0029] See Figures 1 to 10 As shown, an aluminum alloy die-casting apparatus for automotive parts production includes a slitting and unloading device installed beside a metal die-casting machine 1. The slitting and unloading device includes a sorting conveyor 2, a mobile robot 3, and a slitting and picking device 4. The sorting conveyor 2 is located beside the metal die-casting machine 1. A diversion mounting frame 21 is fixedly installed on the metal die-casting machine 1. A detachable limiting slitting seat 23 is installed on the diversion mounting frame 21. The limiting slitting seat 23 cooperates with the diversion mounting frame 21 to sort and convey aluminum alloy die-cast parts 5 and slitting waste. The mobile robot 3 is located beside the sorting conveyor 2. The slitting and picking device 4 is fixedly installed on the movable end of the mobile robot 3. The slitting and picking device 4 has multiple slitting ends and multiple adsorption gripping heads 48 are also installed on the slitting and picking device 4. The adsorption gripping heads 48 are used to grip the aluminum alloy die-cast parts 5.

[0030] Based on the specific shape of the aluminum alloy die-cast part 5, the staff installed the matching limiting and cutting seat 23 onto the diversion mounting frame 21, and installed the matching cutting and picking device 4 onto the moving end of the mobile robot 3.

[0031] In the production process of automotive aluminum alloy die-cast parts 5, a multi-cavity mold is used for production. The metal die-casting machine 1 simultaneously casts multiple aluminum alloy die-cast parts 5 through this mold. After casting is completed, there will be connecting scrap between the multiple aluminum alloy die-cast parts 5, forming an integral continuous casting structure.

[0032] The mobile robot 3 starts, driving the slitting and material handling device 4 to a designated position inside the metal die-casting machine 1. The adsorption gripping head 48 on the slitting and material handling device 4 performs limiting adsorption gripping on the multiple aluminum alloy die-casting parts 5 cast by the metal die-casting machine 1 to ensure the stability of the aluminum alloy die-casting parts 5 during the gripping process.

[0033] The mobile robot 3 continues its operation, moving the slitting and picking device 4 and the gripped aluminum alloy die-casting part 5 directly above the limiting slitting seat 23. At this point, the aluminum alloy die-casting part 5 is fixed in place by the combined action of the adsorption gripping head 48 and the limiting slitting seat 23, providing precise positioning for subsequent cutting operations.

[0034] The cutting end of the slitting and material handling device 4 is activated to cut the aluminum alloy die casting 5 which is in the limit state, cut off the connecting waste, and separate the individual aluminum alloy die castings 5 ​​from each other.

[0035] After the aluminum alloy die-casting part 5 is cut, the adsorption gripping head 48 cancels its adsorption function, and the cut aluminum alloy die-casting part 5 falls below the limiting and slitting seat 23 under the action of gravity. The sorting conveyor 2 starts working, transporting the cut aluminum alloy die-casting part 5 to the processing area. At the same time, the limiting and slitting seat 23, in conjunction with the diversion mounting frame 21, transports the cut connecting waste to the corresponding processing area.

[0036] This invention automates the process of aluminum alloy die casting 5 from casting to cutting, sorting and conveying, effectively improving the production efficiency of aluminum alloy die casting 5, while reducing manpower input and reducing the risk of quality fluctuations caused by manual operation.

[0037] See Figures 1 to 4 As shown, the side of the diversion mounting frame 21 is provided with a discharge port 211, and the inside of the diversion mounting frame 21 is provided with a limiting mounting groove for installing the limiting cutting seat 23. The two sides of the diversion mounting frame 21 are slidably mounted with snap-fit ​​brackets 213, and a first spring 212 is installed between the snap-fit ​​brackets 213 and the diversion mounting frame 21.

[0038] The shape and size of the limiting mounting groove are adapted to the limiting cutting seat 23, providing precise installation space for the limiting cutting seat 23. Snap-fit ​​brackets 213 are slidably mounted on both sides of the diversion mounting bracket 21, and a first spring 212 is installed between the snap-fit ​​brackets 213 and the diversion mounting bracket 21. When the first spring 212 is in its natural state, the snap-fit ​​brackets 213 have a certain initial position under the action of the spring force.

[0039] When the limiting cutter seat 23 needs to be installed on the diversion mounting bracket 21, the operator places the limiting cutter seat 23 into the limiting mounting slot. During the insertion process, the limiting cutter seat 23 will contact the snap-fit ​​bracket 213 and exert a squeezing effect on the snap-fit ​​bracket 213, causing the snap-fit ​​bracket 213 to slide to both sides against the elastic force of the first spring 212.

[0040] Once the limiting slitting seat 23 is fully inserted into the limiting mounting groove and reaches the predetermined position, the snap-fit ​​bracket 213 moves towards the limiting slitting seat 23 under the elastic force of the first spring 212 until the snap-fit ​​bracket 213 engages with the snap-fit ​​part on the limiting slitting seat 23. At this time, the limiting slitting seat 23 is stably positioned and fixed in the limiting mounting groove under the limiting action of the limiting mounting groove and the snap-fit ​​action of the snap-fit ​​bracket 213, ensuring that it will not shake or shift during subsequent production, thereby guaranteeing the accuracy of the slitting operation.

[0041] The diversion mounting frame 21 has a discharge port 211 on its side, which cooperates with the structure of the limiting cutting seat 23. During the cutting process of the aluminum alloy die-casting part 5, after the connecting waste is cut off, it will move along the guide structure of the limiting cutting seat 23 to the discharge port 211 on the side of the diversion mounting frame 21. Since a smooth channel is formed between the discharge port 211 and the limiting cutting seat 23, the waste can be smoothly transported to the processing area through the discharge port 211, realizing automatic classification and transportation of waste, reducing manual intervention and improving production efficiency.

[0042] See Figures 2 to 4 As shown, an anti-blocking device 22 is also installed on the side of the diversion mounting frame 21. The anti-blocking device 22 includes a first mounting bracket 221, a rotating shaft 222, a rotary driver 223, and a conveyor bar 225. The first mounting bracket 221 is fixedly installed on the side of the diversion mounting frame 21. The rotating shaft 222 is rotatably installed on the first mounting bracket 221. The rotary driver 223 is fixedly installed on the first mounting bracket 221, and the output end of the rotary driver 223 is connected to the rotating shaft 222 for transmission. There are multiple conveyor bars 225. Each conveyor bar 225 has multiple rotating rollers inside. The rotating rollers are slidably connected to the rotating shaft 222. A conveyor belt 2252 is sleeved on the outside of the rotating rollers. A fixing buckle 2253 is also provided on the outside of the conveyor bar 225.

[0043] The first mounting bracket 221 is securely fixed to the side of the diversion mounting bracket 21, providing a stable support structure for the entire anti-clogging device 22. The rotating shaft 222 is rotatably mounted on the first mounting bracket 221 and can rotate around its own axis, providing a foundation for subsequent power transmission and the rotation of the conveyor strip 225. The rotary actuator 223 is fixedly mounted on the first mounting bracket 221, and its output end is connected to the rotating shaft 222, enabling accurate transmission of power from the rotary actuator 223 to the rotating shaft 222.

[0044] Each conveyor bar 225 has multiple rotating rollers inside, which are slidably connected to the rotating shaft 222, allowing the conveyor bar 225 to slide and adjust along the rotating shaft 222. After the limiting slitting seat 23 is installed on the diversion mounting frame 21, the operator slides the multiple conveyor bars 225 to the appropriate position along the rotating shaft 222 according to the actual production needs and the position of the limiting slitting seat 23. Then, using the fixing buckles 2253 provided on the outside of the conveyor bar 225, the end of the conveyor bar 225 away from the rotating shaft 222 is fixedly connected to the limiting slitting seat 23, ensuring that the conveyor bar 225 maintains a stable position and posture during operation.

[0045] During the process of slitting aluminum alloy die-casting parts 5 by the limiting slitting seat 23 and the slitting and unloading device 4, after the connecting waste separates from the aluminum alloy die-casting parts 5, some waste will fall above the limiting slitting seat 23, while the other part will directly contact the conveyor belt 2252 of the conveyor bar 225. At this time, without the anti-blocking device 22, the waste may accumulate above the limiting slitting seat 23 or block the conveying path, affecting the continuity and efficiency of production.

[0046] To ensure stable detachment and smooth conveying of waste, the rotary drive 223 is activated, driving the rotating shaft 222 to rotate around its own axis. Since the rotating roller is slidably connected to the rotating shaft 222 and can rotate relative to it, the rotation of the rotating shaft 222 will cause the rotating roller to rotate synchronously. A conveyor belt 2252 is fitted around the outside of the rotating roller, and the rotation of the rotating roller will further drive the conveyor belt 2252 to circulate.

[0047] Driven by the rotating rollers and conveyor belt 2252, the conveyor bar 225 begins to rotate. The rotation of the conveyor bar 225 generates a pushing force on the waste material in contact with it, towards the discharge port 211 on the side of the diversion mounting frame 21. Simultaneously, waste material falling above the limiting slitting seat 23 and close to the conveyor bar 225 will also gradually move towards the discharge port 211 under the influence of the rotating conveyor bar 225. Finally, under the continuous rotation of the conveyor bar 225, the waste material falls into the processing area through the discharge port 211 of the diversion mounting frame 21, achieving automatic and stable waste material conveying, effectively avoiding waste material blockage, and improving the efficiency and reliability of the entire aluminum alloy die-casting part production process 5.

[0048] See Figure 4 and Figure 5 As shown, the bottom of the limiting slitting seat 23 is an inclined material guiding surface 231. The limiting slitting seat 23 is provided with multiple limiting dropping tools 232. The limiting dropping tools 232 are provided with dropping holes inside. The bottom of the limiting slitting seat 23 is provided with two sets of buffer dropping mechanisms 234. The limiting slitting seat 23 is also provided with multiple positioning holes 233.

[0049] The limiting slitting seat 23 is equipped with multiple positioning holes 233. The size and position of the positioning holes 233 are precisely designed to match the positioning structure of the slitting and unloading device 4. When the mobile robot 3 moves the slitting and unloading device 4, the slitting and unloading device 4 is precisely positioned according to the positioning holes 233 on the limiting slitting seat 23, ensuring that it can accurately move to directly above the limiting unloading fixture 232. This process provides a precise positioning reference for the subsequent stable gripping and slitting operation of the aluminum alloy die-casting part 5, ensuring the accuracy and consistency of the entire production process.

[0050] The limiting slitting seat 23 is equipped with multiple limiting unloading tools 232. The shape of the limiting unloading tools 232 is customized according to the specific shape of the aluminum alloy die casting 5, so that it can fit tightly with the aluminum alloy die casting 5. When the mobile robot 3 moves the slitting and picking device 4 and the grasped aluminum alloy die casting 5 directly above the limiting unloading tools 232, the adsorption gripping head 48 continuously applies an adsorption force to the aluminum alloy die casting 5. At the same time, the aluminum alloy die casting 5 falls into the limiting unloading tool 232. Under the combined action of the adsorption gripping head 48 and the limiting unloading tool 232, the aluminum alloy die casting 5 is firmly limited and fixed. This dual limiting method effectively prevents the aluminum alloy die casting 5 from shaking and displacement during the slitting process, provides stable conditions for the slitting operation, and ensures slitting accuracy and quality.

[0051] After the aluminum alloy die-cast part 5 is fixed in place, the cutting end of the cutting and feeding device 4 is activated to cut the connecting waste on the aluminum alloy die-cast part 5. During the cutting process, the waste generated will slide along the inclined guide surface 231 at the bottom of the limiting cutting seat 23 towards the outlet 211 of the diversion mounting frame 21 under the action of gravity. This inclined guide surface 231 design effectively guides the flow direction of the waste, preventing it from accumulating on the limiting cutting seat 23 and ensuring that the waste can be smoothly transported to the designated processing area, thus achieving automatic classification and transportation of the waste.

[0052] The bottom of the limiting and cutting seat 23 is equipped with two sets of buffer unloading mechanisms 234. When the cut aluminum alloy die-cast parts 5 fall from the unloading holes of the limiting unloading tool 232, they enter the buffer unloading mechanisms 234. The buffer unloading mechanisms 234 buffer the falling aluminum alloy die-cast parts 5 through their internal structural design, slowing down the falling speed of the aluminum alloy die-cast parts 5 and preventing damage or excessive noise caused by direct impact with the sorting conveyor 2. After buffering, the aluminum alloy die-cast parts 5 can fall stably onto the sorting conveyor 2, and then be transported to the processing area by the sorting conveyor 2, further improving the stability and reliability of the production process.

[0053] See Figure 5 and Figure 6 As shown, the buffer unloading mechanism 234 includes a clamping plate 2341, a telescopic rod 2342, a second spring 2343, and a connecting rod 2344. Two clamping plates 2341 are provided, and the clamping plates 2341 are slidably connected to the limiting slitting seat 23. Multiple limiting buffer grooves are provided on the clamping plates 2341, and multiple flexible strips are provided inside each limiting buffer groove. The telescopic rod 2342 is slidably mounted on the limiting slitting seat 23. The second spring 2343 is located between the telescopic rod 2342 and the limiting slitting seat 23. Multiple connecting rods 2344 are provided and distributed on the two clamping plates 2341. One end of the connecting rod 2344 is rotatably connected to the clamping plate 2341, and the end of the connecting rod 2344 away from the clamping plate 2341 is rotatably connected to the telescopic rod 2342.

[0054] As the mobile robot 3 moves the slitting and picking device 4 and the gripped aluminum alloy die-casting part 5 directly above the limiting and unloading fixture 232, the slitting and picking device 4 exerts a pressing force on the telescopic rod 2342. After being pressed, the telescopic rod 2342 begins to move. Since one end of the connecting rod 2344 is rotatably connected to the telescopic rod 2342 and the other end is rotatably connected to the clamping plate 2341, the movement of the telescopic rod 2342 will cause the connecting rod 2344 to move synchronously, thereby bringing the two clamping plates 2341 closer together. During this process, the second spring 2343 is compressed due to the movement of the telescopic rod 2342, storing elastic potential energy.

[0055] After the slitting and feeding device 4 completes the slitting operation on the waste material on the aluminum alloy die casting 5, the aluminum alloy die casting 5 passes through the limiting discharge tool 232, enters the limiting buffer groove, and begins to fall. The flexible strip in the limiting buffer groove contacts the aluminum alloy die casting 5. Through the elastic deformation and friction of the flexible strip, the falling speed of the aluminum alloy die casting 5 is effectively reduced, avoiding damage or excessive noise caused by direct impact with the sorting conveyor 2, until the aluminum alloy die casting 5 falls smoothly onto the sorting conveyor 2.

[0056] When the cutting and feeding device 4 resets, its resistance to the telescopic rod 2342 disappears, and the second spring 2343 releases its stored elastic potential energy, pushing the telescopic rod 2342 to move in the opposite direction. The reverse movement of the telescopic rod 2342 drives the connecting rod 2344 to move, thereby causing the two clamping plates 2341 to expand and reset, preventing the unfallen aluminum alloy die-casting part 5 from remaining in the limiting buffer groove. This ensures that the buffer feeding mechanism 234 can work continuously and stably, providing reliable buffer feeding support for the production process of the aluminum alloy die-casting part 5, and further improving the stability and reliability of the production process.

[0057] See Figures 1 to 10 As shown, the slitting and material handling device 4 includes a fixed mounting plate 41, a synchronous pressing plate 42, a third spring 43, a segmented mounting fixture 44, a trimming mounting fixture 45, a slitting blade 46, and an auxiliary pressing device 47. One side of the fixed mounting plate 41 is fixedly connected to the movable end of the mobile robot 3. The fixed mounting plate 41 has multiple sliding mounting holes, and multiple positioning shafts 411 are installed below the fixed mounting plate 41. The synchronous pressing plate 42 is slidably mounted on the fixed mounting plate 41. The third spring 43 is installed between the fixed mounting plate 41 and the synchronous pressing plate 42. Multiple segmented mounting fixtures 44 are provided and distributed on the synchronous pressing plate 41. On plate 42, segmented mounting fixture 44 is fixedly connected to synchronous pressing plate 42; multiple trimming mounting fixtures 45 are provided and evenly distributed on synchronous pressing plate 42, the outer side of trimming mounting fixture 45 is slidably connected to fixed mounting plate 41, the top of trimming mounting fixture 45 is fixedly connected to synchronous pressing plate 42, and trimming mounting fixture 45 is slidably connected to adsorption gripping head 48; multiple slitting blades 46 are provided and evenly distributed on segmented mounting fixture 44 and trimming mounting fixture 45, and slidably connected to segmented mounting fixture 44 and trimming mounting fixture 45; auxiliary pressing device 47 is fixedly installed above diversion mounting frame 21.

[0058] During the production of automotive aluminum alloy die-cast parts 5, the mobile robot 3 starts and moves the fixed mounting plate 41, thereby moving the entire slitting and material handling device 4. When the fixed mounting plate 41 moves above the limiting slitting seat 23, the positioning shaft 411 below it aligns with the corresponding positioning hole 233 on the limiting slitting seat 23, ensuring that the fixed mounting plate 41 can stably stay in the designated position. At this time, the adsorption gripping head 48 has gripped the aluminum alloy die-cast part 5 and brought it to stay on the limiting slitting seat 23.

[0059] Subsequently, the auxiliary pressing device 47 starts working, applying pressure to the synchronous pressing plate 42. Under the action of pressure, the synchronous pressing plate 42 moves downward against the elastic force of the third spring 43, pushing the segmented mounting fixture 44 and the trimming mounting fixture 45, which are fixedly connected to it, to press down synchronously.

[0060] During the pressing process, the slitting blades 46 mounted on the segmented mounting fixture 44 and the trimming mounting fixture 45 perform a slitting operation on the aluminum alloy die casting 5. Specifically, the slitting blades 46 on the trimming mounting fixture 45 slit along the edge of the aluminum alloy die casting 5 to remove excess waste material at the edge and ensure the dimensional accuracy of the edge of the aluminum alloy die casting 5; the slitting blades 46 on the segmented mounting fixture 44 slit the connecting waste material between the aluminum alloy die castings 5, dividing the overall continuous casting structure into independent aluminum alloy die castings 5. At the same time, this segmented slitting method facilitates the subsequent unloading and disposal of waste material.

[0061] After the cutting is completed, the adsorption gripping head 48 cancels its adsorption function, and the cut aluminum alloy die castings 5 ​​fall under gravity. They are then transported to the corresponding processing area via the limiting cutting seat 23 and the sorting conveyor 2. The cut waste is also transported to the designated waste processing area via the limiting cutting seat 23 and the diversion mounting frame 21, completing the entire cutting and material handling process of the aluminum alloy die castings 5. This cutting and material handling device 4, through the coordinated work of its components, achieves precise cutting and efficient material handling of the aluminum alloy die castings 5, improving production efficiency and product quality.

[0062] See Figures 8 to 10 As shown, the trimming and mounting fixture 45 has a mounting hole on its shaft. The shaft mounting hole 451 is used to install the adsorption gripper head 48. The bottom of the trimming and mounting fixture 45 has multiple tool mounting slots 452. The tool mounting slots 452 match the shape of the aluminum alloy die casting part 5. The tool mounting slots 452 are used to fix and install the slitting blade 46.

[0063] During the production of automotive aluminum alloy die-cast parts 5, when the mobile robot 3 moves the slitting and picking device 4 to the designated position, and the fixed mounting plate 41 is stably positioned above the limiting slitting seat 23 via the positioning shaft 411, the adsorption gripping head 48 picks up the aluminum alloy die-cast part 5 and places it on the limiting slitting seat 23. Then, the auxiliary pushing device 47 begins to apply pressure to the synchronous pushing plate 42. The synchronous pushing plate 42 moves downward against the elastic force of the third spring 43. Since the top of the trimming mounting fixture 45 is fixedly connected to the synchronous pushing plate 42 and the outer side is slidably connected to the fixed mounting plate 41, the trimming mounting fixture 45 will press down synchronously with the synchronous pushing plate 42. During the pressing process, the slitting blade 46 installed in the tool mounting groove 452 at the bottom of the trimming mounting fixture 45 will contact the edge of the aluminum alloy die-cast part 5. Since the tool mounting groove 452 matches the shape of the aluminum alloy die-cast part 5, the slitting blade 46 can perform precise slitting operations along the edge of the aluminum alloy die-cast part 5, removing excess waste material from the edge. This precise cutting method can effectively ensure the edge dimensional accuracy of the aluminum alloy die casting 5, making it meet design requirements and improving product quality.

[0064] After the slitting is completed, the adsorption gripping head 48 cancels the adsorption function, and the aluminum alloy die casting 5 falls under the action of gravity and is transported to the corresponding processing area through the limiting slitting seat 23 and the sorting conveyor 2.

[0065] See Figures 2 to 3 As shown, the auxiliary pushing device 47 includes a second mounting bracket 471, a pressure plate 472, and a linear driver 473; the second mounting bracket 471 is fixedly mounted on the diverter mounting bracket 21; the linear driver 473 is fixedly mounted on the second mounting bracket 471; and the pressure plate 472 is fixedly mounted on the output end of the linear driver 473.

[0066] During the production of automotive aluminum alloy die-cast parts 5, when the fixed mounting plate 41 moves to the limit cutting seat 23 and is stably positioned under the drive of the mobile robot 3, and the adsorption gripping head 48 has gripped the aluminum alloy die-cast part 5 and placed it on the limit cutting seat 23, the linear actuator 473 starts to work. The linear actuator 473 pushes the pressure plate 472 towards the synchronous push plate 42. After the pressure plate 472 contacts the synchronous push plate 42, it applies a stable downward pressure to it.

[0067] After being pressed by the pressure plate 472, the synchronous push plate 42 overcomes the elastic force of the third spring 43 between the fixed mounting plate 41 and the synchronous push plate 42, and begins to move downward. Since the segmented mounting fixture 44 and the trimming mounting fixture 45 are both fixedly connected to the synchronous push plate 42, they will press down synchronously with the synchronous push plate 42. The slitting blades 46 installed on the segmented mounting fixtures 44 and the trimming mounting fixtures 45 also move downward, performing a slitting operation on the aluminum alloy die casting 5. Among them, the slitting blades 46 on the trimming mounting fixture 45 slit along the edge of the aluminum alloy die casting 5, removing excess waste material from the edge and ensuring the edge dimensional accuracy of the aluminum alloy die casting 5; the slitting blades 46 on the segmented mounting fixture 44 slit the connecting waste between the aluminum alloy die castings 5, dividing the overall continuous casting structure into independent aluminum alloy die castings 5, while facilitating the subsequent unloading of waste material.

[0068] After the slitting is completed, the linear actuator 473 drives the pressure plate 472 to move in the opposite direction, releasing the pressure on the synchronous push plate 42. The synchronous push plate 42 returns to its initial position under the action of the third spring 43, preparing for the next slitting operation. Through this precise push control, the auxiliary push device 47 ensures that the slitting and material handling device 4 can stably and efficiently complete the slitting task of the aluminum alloy die casting 5, improving production efficiency and product quality.

[0069] See Figures 8 to 10 As shown, the adsorption gripping head 48 is slidably installed in the mounting hole of the trimming mounting fixture 45. The bottom of the adsorption gripping head 48 is provided with a mating contact head 481 that abuts against the inner wall of the aluminum alloy die-cast part 5. The mating contact head 481 is provided with a plurality of adsorption holes 482. A fourth spring 483 is also installed on the adsorption gripping head 48. The end of the fourth spring 483 away from the adsorption gripping head 48 abuts against the trimming mounting fixture 45.

[0070] During the adsorption and material handling stage, the mobile robot 3 moves the slitting and material handling device 4 to the location of the aluminum alloy die-casting part 5, and the adsorption gripping head 48 moves along with the device. When the bottom contact head 481 of the adsorption gripping head 48 contacts the inner wall of the aluminum alloy die-casting part 5, the adsorption function is activated, and the adsorption hole 482 generates a negative pressure suction force. This suction force acts on the inner wall of the aluminum alloy die-casting part 5, making the aluminum alloy die-casting part 5 fit tightly against the adsorption gripping head 48, thereby positioning and fixing the aluminum alloy die-casting part 5, facilitating subsequent movement and processing operations.

[0071] During the slitting stage of aluminum alloy die casting 5 and scrap, the slitting and unloading device 4 moves directly above the limiting slitting seat 23. At this time, the aluminum alloy die casting 5, which is adsorbed and fixed, stays on the limiting unloading tool 232. Subsequently, the auxiliary pushing device 47 starts to work, applying pressure to the synchronous pushing plate 42. The synchronous pushing plate 42 overcomes the elastic force of the third spring 43 and moves downward, thereby pushing the segmented mounting tool 44 and the trimming mounting tool 45, which are fixedly connected to it, to press down synchronously.

[0072] During the downward pressing process of the trimming fixture 45, the aluminum alloy die-cast part 5, which is already fixed to the adsorption gripping head 48, obstructs the adsorption gripping head 48, preventing it from descending with the trimming fixture 45. At this time, the fourth spring 483 is compressed by the downward pressure of the trimming fixture 45, generating elastic potential energy. As the trimming fixture 45 continues to press down, the slitting blade 46 mounted on it gradually approaches the edge of the aluminum alloy die-cast part 5 and performs a slitting operation on the edge waste. When the slitting blade 46 on the trimming fixture 45 has completely removed the waste from the edge of the aluminum alloy die-cast part 5, the obstruction effect of the aluminum alloy die-cast part 5 on the adsorption gripping head 48 disappears.

[0073] At this point, the elastic potential energy stored in the fourth spring 483 is released, generating a rebound force that pushes the adsorption gripper head 48. Subsequently, the adsorption gripper head 48 cancels its adsorption effect on the aluminum alloy die-casting part 5. The slit aluminum alloy die-casting part 5 is pushed down and moved, allowing it to pass smoothly through the limiting slitting seat 23 and finally fall onto the sorting conveyor 2 for transport to the corresponding processing area.

[0074] Specific working principle: In the production of automotive aluminum alloy die casting parts 5, a multi-cavity mold is used to simultaneously cast multiple aluminum alloy die casting parts 5 in a metal die casting machine 1. After casting, an integral continuous casting structure is formed, and there is connecting waste between each die casting part.

[0075] According to the specific shape of the aluminum alloy die-cast part 5, the staff installed the appropriate limiting and cutting seat 23 onto the diversion mounting frame 21, and at the same time fixed the appropriate cutting and picking device 4 to the moving end of the mobile robot 3.

[0076] The mobile robot 3 starts, driving the slitting and material handling device 4 to a designated position inside the metal die-casting machine 1. The adsorption gripping head 48 of the slitting and material handling device 4 performs limiting adsorption gripping on multiple aluminum alloy die-cast parts 5 to ensure the stability of the gripping process.

[0077] Subsequently, the mobile robot 3 continues its operation, moving the slitting and material handling device 4 and the gripped die-cast part directly above the limiting slitting seat 23. At this time, the positioning shaft 411 below the fixed mounting plate 41 aligns with the positioning hole 233 on the limiting slitting seat 23, achieving precise positioning. The adsorption gripping head 48 continues to adsorb, while the aluminum alloy die-cast part 5 falls into the limiting unloading tool 232, which is customized to its own shape and fits tightly. Under the combined action of the adsorption gripping head 48 and the limiting unloading tool 232, the aluminum alloy die-cast part 5 is firmly limited and fixed, preventing shaking and displacement during slitting and providing stable conditions for the slitting operation.

[0078] The auxiliary pressing device 47 starts working, applying pressure to the synchronous pressing plate 42. The synchronous pressing plate 42 moves downward against the elastic force of the third spring 43, pushing the segmented mounting fixture 44 and the trimming mounting fixture 45, which are fixedly connected to it, to press down synchronously. The cutting blade 46 on the trimming mounting fixture 45 cuts along the edge of the aluminum alloy die casting 5 to remove excess waste and ensure the edge dimensional accuracy; the cutting blade 46 on the segmented mounting fixture 44 cuts the connecting waste into segments, dividing the integral continuous casting into independent die castings, which facilitates subsequent waste unloading and processing.

[0079] The waste generated during the slitting process is automatically sorted and transported by sliding along the inclined guide surface 231 at the bottom of the limiting slitting seat 23 towards the discharge port 211 of the diversion mounting frame 21 under the action of gravity due to the design of the inclined guide surface 231 at the bottom of the limiting slitting seat 23.

[0080] After the cutting is completed, the adsorption gripper 48 cancels the adsorption, and the cut aluminum alloy die casting 5 enters the buffer feeding mechanism 234 through the feeding hole of the limiting feeding tool 232. After buffering, it falls stably to the classification conveyor 2, which transports it to the processing area. The cut waste is transported to the designated waste processing area through the limiting cutting seat 23 and the diversion mounting frame 21, completing the entire cutting and material handling process. This realizes the automation of the aluminum alloy die casting 5 from casting to cutting, classification and conveying, improving production efficiency and product quality.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
