[0047] With the rapid development of the automotive industry, in order to meet the needs of users, the model iteration speed is getting faster and faster, and the vehicle manufacturing cycle is rapidly shortened, thus driving the development of automotive parts towards the direction of high integration and lightweight. The die-casting aluminum alloy process in the automotive industry has the advantages of high dimensional accuracy, good surface finish, high dimensional stability, the ability to form complex shapes, and high production efficiency.

[0048] Among them, the integration and lightweight of the vehicle body have become the key research directions for new energy vehicles. Integral die-casting is an important means for vehicle body integration and lightweight. However, due to the complex and diverse body structures, multiple gates are required for the aluminum alloy casting process, which results in two or more slag pockets that need to be removed in a relatively small space. As Figure 1 and Figure 2 shown, it is a die-casting part 100 with a double-layer slag pocket structure. The die-casting part 100 includes a workpiece 11, and an upper edge part 12 and a lower edge part 13 that are connected to the same side of the workpiece 11 and are distributed vertically. An upper slag pocket 14 remains on the outer side of the upper edge part 12, and a lower slag pocket 15 remains on the outer side of the lower edge part 13. Among them, the connection between the upper edge part 12 and the upper slag pocket 14 is an upper cut 16, and the connection between the lower edge part 13 and the lower slag pocket 15 is a lower cut 17. For the removal of the slag pockets of the die-casting part 100, the prior art generally uses two sets of cutting devices to remove the upper slag pocket 14 and the lower slag pocket 15 separately in two steps. However, the existing step-by-step removal method results in complex equipment and increased die-casting time, affecting production efficiency and production costs.

[0049] To solve the above problems, this embodiment discloses a double-layer slag pocket removal device 200, which aims to quickly complete the removal of the upper slag pocket 14 and the lower slag pocket 15, thereby improving processing efficiency and quality.

[0050] Please refer to Figures 3 to 15 . In this embodiment, a double-layer slag pocket removal device 200 is proposed for removing the upper slag pocket 14 and the lower slag pocket 15 connected to the workpiece 11. It includes an upper slag pocket removal unit 21 and a lower slag pocket removal unit 22. The upper slag pocket removal unit 21 is used to remove the upper slag pocket 14, and the lower slag pocket removal unit 22 is used to remove the lower slag pocket 15. During the slag pocket removal process, the upper slag pocket 14 is located above the lower slag pocket 15, so it is also called a double-layer slag pocket.

[0051] Among them, the upper slag pocket removal unit 21 includes: a clamping assembly 212 and an upper cutter assembly 213. The clamping assembly 212 is used to clamp the workpiece 11, and the upper cutter assembly 213 is used to remove the upper slag pocket 14. Specifically, when removing the upper slag pocket 14, the clamping assembly 212 clamps on the top surface of the upper edge part 12 of the workpiece 11, so as to avoid damaging the workpiece 11 when removing the upper slag pocket 14. The bottom surface of the upper edge part 12 of the workpiece 11 is supported by the lower slag pocket removal unit 22.

[0052] The lower slag pocket removal unit 22 includes: a lower cutter assembly and a driving assembly 23 for driving the lower cutter assembly to move. The driving assembly 23 drives the lower cutter assembly to approach and remove the lower slag pocket 15.

[0053] Please refer to Figures 9 to 14 The lower cutting tool assembly includes: a lower cutting tool 224, a lower connecting plate 223, and a lower support plate 222 arranged parallel to the lower connecting plate 223. A guiding hole 2220 is provided on the lower support plate 222. The driving assembly 23 includes a driving block 225. The driving block 225 passes through the guiding hole 2220 and its rear end 2252 is connected to the lower connecting plate 223. The front end 2253 of the driving block 225 abuts against the lower cutting tool 224. The lower cutting tool 224 is connected to the lower support plate 222, and the lower support plate 222 and the lower cutting tool 224 are guidingly connected in a second direction. Guiding connection means that there is a fixed moving direction between the two. Wherein the lower connecting plate 223 is connected to the driving end of the driving assembly 23. The driving block 225 moves along a first direction following the lower connecting plate 223. When the driving block 225 moves in the first direction, it synchronously drives the lower cutting tool 224 to move in the second direction, where the first direction and the second direction are perpendicular to each other. In this embodiment, the first direction is the horizontal left-right direction, and the second direction is the vertical direction.

[0054] In this embodiment, since the interval space between the upper slag pocket 14 and the lower slag pocket 15 in the vertical direction is small and cannot accommodate a larger-structured lower cutting tool assembly to extend into this space for operation, therefore, this lower cutting tool assembly adopts the perpendicular-direction movement of the driving block 225 and the lower cutting tool 224 to solve the above-mentioned small-space problem. It should be noted that the first direction and the second direction in this embodiment are not limited to the horizontal direction and the vertical direction in this embodiment. They are only used to illustrate their relative directions. In other embodiments, they can be other orientations according to the actual slag pocket position and process requirements of the die-cast part.

[0055] Wherein, a first elastic resetting member 2232 is further provided between the lower connecting plate 223 and the lower support plate 222. One end of the first elastic resetting member 2232 is connected to the lower connecting plate 223, and the other end is connected to the lower support plate 222. When the lower connecting plate 223 is controlled to approach the lower support plate 222, the first elastic resetting member 2232 is compressed.

[0056] Such as Figure 10 and Figure 12As shown, the lower edge portion 13 of the workpiece 11 is substantially perpendicular to the workpiece 11. When the driving assembly 23 drives the lower cutting tool assembly to move from right to left and approach the lower edge portion 13, the lower support plate 222 first approaches and abuts against the lower edge portion 13. Since there must be inertia when the driving assembly 23 performs the driving action, a first elastic reset member 2232 is provided between the lower support plate 222 and the lower connecting plate 223 to reduce the rigid impact on the lower edge portion 13 when the lower support plate 222 approaches it. When the driving assembly 23 drives the lower cutting tool assembly to approach the lower edge portion 13, the lower support plate 222 first contacts the lower edge portion 13, and the driving assembly 23 continues to drive the lower cutting tool assembly to move. Under the elastic buffering action of the first elastic reset member 2232, the lower connecting plate 223 is driven to continue approaching the lower edge portion 13. At the same time, the lower cutting tool 224 is driven to descend to complete the removal of the lower slag pocket 15.

[0057] Specifically, the first elastic reset member 2232 is a combined structure of a connecting rod and a spring sleeved on the connecting rod. One end of the connecting rod is movably inserted into the lower support plate 222, and the other end is fixedly connected to the lower connecting plate 223. Of course, the first elastic reset member 2232 can also be an elastic member structure inserted into the jacks on the opposite surfaces of the lower support plate 222 and the lower connecting plate 223. In order to improve the stability of the opening and closing movement between the lower connecting plate 223 and the lower support plate 222, a limiting mechanism in which a guiding cylinder cooperates with a guiding circular hole can also be provided between the two.

[0058] When the driving assembly 23 drives the lower connecting plate 223 in the reverse direction, the first elastic reset member 2232 synchronously drives the lower connecting plate 223 and the lower support plate 222 to move away from each other until the first elastic reset member 2232 is completely reset, so as to provide buffering for the next removal action.

[0059] Please refer to again Figure 9 , the lower slag pocket removing unit 22 further includes a lower support member 221. The lower support member 221 is located at the bottom of the workpiece 11, and its end abuts against the left side surface 131 of the lower edge portion 13, and is used to cooperate with the lower cutting tool 224 to cut off the lower slag pocket 15 from the lower cut 17. The lower support member 221 provides support for the part of the workpiece 11 near the lower edge portion 13 from the bottom and the left side surface 131 of the lower edge portion 13, preventing damage to the workpiece 11 when the lower slag pocket 15 is removed and improving its process quality.

[0060] As Figure 11 and Figure 14As shown, a guide rail 2222 extending in the second direction is provided on the lower support plate 222, and a guide groove 2243 corresponding to the guide rail 2222 is provided on the lower cutting knife 224. The guide rail 2222 extends vertically downward from the bottom of the main body of the lower support plate 222. The guide groove 2243 on the lower cutting knife 224 is a through groove extending vertically on both sides of the main body of the lower cutting knife 224. During assembly, the lower cutting knife 224 moves upward from the bottom of the lower support plate 222, and the guide rail 2222 is inserted into the guide groove 2243. The guide groove 2243 is used to guide and limit the vertical movement of the lower cutting knife 224 so that the cutting edge 2241 accurately acts on the lower cut 17 after descending.

[0061] It can be understood that in other embodiments, the guide groove 2243 can be provided on the lower support plate 222, and the corresponding guide rail 2222 is provided on the lower cutting knife 224.

[0062] Please refer to again Figure 13 and Figure 14 As shown, a cutting edge 2241 is provided on the lower edge of the lower cutting knife 224, a second inclined surface 2242 is provided on its top, a first inclined surface 2251 is provided on the driving block 225, and the first inclined surface 2251 is attached to the second inclined surface 2242. When the driving block 225 moves toward the lower cutting knife 224, the first inclined surface 2251 acts on the second inclined surface 2242, causing the lower cutting knife 224 to move vertically downward. In this embodiment, by using the cooperation of the inclined surfaces of the driving block 225 and the lower cutting knife 224, the horizontal movement of the driving block 225 drives the vertical movement of the lower cutting knife 224, thus solving the problem of inconvenient removal of the slag pockets in the relatively small longitudinal space between the upper slag pocket 14 and the lower slag pocket 15. In other embodiments, other structures can also be used for the cooperation between the driving block 225 and the lower cutting knife 224, and the purpose is to realize the switching between the horizontal movement and the vertical movement.

[0063] Further, a limiting hole 2244 is also provided on the lower cutting knife 224, a limiting post 226 is arranged in the limiting hole 2244, one end of the limiting post 226 is fixedly connected to the lower connecting plate 223, and the limiting hole 2244 is a vertically extending waist-shaped hole, which is used to limit the vertical lifting stroke of the lower cutting knife 224.

[0064] As Figure 14 shown, a connecting hole 2245 is also provided at the bottom of the lower cutting knife 224, a second elastic resetting member (not shown in the figure) is arranged in the connecting hole 2245. When the driving block 225 is reset, the lower cutting knife 224 is reset in the second direction under the action of the second elastic resetting member, that is, the second elastic resetting member drives the lower cutting knife 224 to rise and reset. Here, the reset means the state of the lower cutting knife 224 before performing the action of removing the lower slag pocket. The second elastic resetting member can be an elastic member such as a spring.

[0065] As shown Figure 11 in the figure, a buffer plate 227 is further provided on the outer side surface 2245 of the lower cutting knife 224. At least part of the upper edge of the buffer plate 227 is higher than the second inclined surface 2242, and the side surface 2271 of the buffer plate 227 protrudes from the outer side surface 2245 of the lower cutting knife 224. When the lower cutting knife assembly approaches the lower edge portion 13 of the workpiece 11, the buffer plate 227 protrudes from the outer side surface 2245 of the lower cutting knife 224. Therefore, the buffer plate 227 contacts the lower edge portion 13 of the workpiece 11 first. The buffer plate 227 is made of a soft material and has certain elastic buffering characteristics, reducing the damage to the surface of the workpiece 11 caused by the rigid contact between the lower cutting knife assembly and the workpiece 11. At the same time, the upper edge of the buffer plate 227 is higher than the upper edge of the second inclined surface 2242, which prevents the driving block 225 from moving beyond the limit and avoids the rigid contact between the end of the driving block 225 and the workpiece 11.

[0066] Please refer to again Figure 11 , a butt joint surface 2231 for aligning with the upper cutting knife assembly 213 is further provided on the top of the lower connecting plate 223, and a clamping surface 2221 for aligning with the clamping assembly 212 is further provided on the top of the lower support plate 222. The shapes of the butt joint surface 2231 and the clamping surface 2221 are determined by the structure of the part of the workpiece 11 close to the edge of the slag pocket, so that the workpiece 11 can be closely attached to the butt joint surface 2231 and the clamping surface 2221 well. When the upper slag pocket 14 is cut off, stable support is provided for the workpiece 11 to avoid damage to the workpiece 11.

[0067] Please refer to again Figure 15 , the driving assembly 23 includes: a mounting plate 231, a driving module 232 connected to the rear side surface 2310 of the mounting plate 231, a plurality of guide rods 233 passing through the mounting plate 231, and a driving connecting plate 234 connected to the front end of the guide rod 233. The driving end 2321 of the driving module 232 is connected to the driving connecting plate 234, and the driving connecting plate 234 is connected to the lower connecting plate 223. When the driving end 2321 of the driving module 232 moves, it drives the driving connecting plate 234 to move in the first direction, so as to synchronously drive the driving block 225 to move.

[0068] To improve the stability of the movement of the driving component 23, several of the guiding rods 233 are also passed through a guiding support plate 239. The guiding support plate 239 is located between the driving connection plate 234 and the mounting plate 231, and the three are arranged in parallel to ensure that the several guiding rods 233 are kept parallel to each other. Among them, a guiding block 235 is fixedly connected to the guiding rod 233 located below. A guide rail 236 is provided below the guiding block 235. The guiding block 235 is fixedly connected to the driving connection plate 234. The driving module 232 drives the driving connection plate 234 to linearly reciprocate in the first direction along the guide rail 236. Among them, preferably two sets of the guiding block 235 and the corresponding guide rail 236 are provided. In this embodiment, the guide rail 236 is connected to the bottom of the mounting plate 231. A connecting member 237 is further provided on the rear side surface of the mounting plate 231. Two travel sensors 238 are provided on the connecting member 237. The two travel sensors 238 are used to detect the position of the rear end of one of the guiding rods 233, so as to control the driving stroke of the driving module 232 and provide a control trigger signal for the driving module 232. In this embodiment, the driving module 232 can be an optional linear driving unit such as a cylinder, an electric cylinder or a servo mechanism, etc.

[0069] Please refer to again Figures 5 to 8 , the upper slag bag removing unit 21 includes an upper connection plate 211. Both the clamping assembly 212 and the upper cutter assembly 213 are connected to the upper connection plate 211. The clamping assembly 212 includes an upper clamping block 2121 and a third elastic reset member 2123 connected to the upper clamping block 2121. The top of the third elastic reset member 2123 is connected to the upper connection plate 211. A guiding column 2122 is further provided between the upper connection plate 211 and the upper clamping block 2121 to keep the upper clamping block 2121 capable of only lifting and lowering in the vertical direction.

[0070] The upper cutter assembly 213 includes: a cutter connection block 2131, and a first upper cutter 2132 and a second upper cutter 214 fixedly connected to the cutter connection block 2131. In another embodiment, the first upper cutter 2132 and the second upper cutter 214 can be directly fixedly connected to the upper connection plate 211.

[0071] Among them, a driving unit (such as a machine tool or a lifting power module) for driving the upper slag bag removing unit 21 to lift and lower in the vertical direction is further connected to the upper connection plate 211. The driving end of the driving unit is connected to the upper connection plate 211.

[0072] When the driving unit drives the upper slag package removing unit 21 to descend, the upper clamping block 2121 contacts the workpiece 11 first, and then the driving unit continues to drive the upper slag package removing unit 21 to descend until the first upper cutting knife 2132 cuts off the upper slag package 14 from the upper notch 16. A third elastic resetting member 2123 is arranged between the upper connecting plate 211 and the upper clamping block 2121, which can reduce the rigid damage when the upper clamping block 2121 contacts the workpiece 11 during descent and provide a buffering effect for the upper clamping block 2121.

[0073] Please refer to again Figure 2 and Figure 5 , the lower slag package 15 includes: a lower slag package block 151 and an upper slag package block 152, and there is a height difference between the upper slag package block 152 and the lower slag package block 151. The upper slag package block 152 is in an upturned state compared with the lower slag package block 151. Therefore, another upper cutting knife 214 is also provided on the cutter connecting block 2131. This upper cutting knife 214 is used to follow the upper slag package removing unit 21 to cut off the upper slag package block 152 of the lower slag package 15, while the lower slag package removing unit 22 is only used to cut off the lower slag package block 151 of the lower slag package 15. In this embodiment, according to the special structures of the upper slag package 14 and the lower slag package 15 on the die-casting part 100, the upper slag package block 152 on the lower slag package 15 is ingeniously cut off by the upper slag package removing unit 21, which simplifies the structure and does not affect the removal process of the double-layer slag package.

[0074] In another embodiment, the first upper cutting knife 2132 and the second upper cutting knife 214 can also be directly connected to the upper connecting plate 211. The first upper cutting knife 2132 is used to cut off the upper slag package 14, and the second upper cutting knife 214 is used to cut off the upper slag package block 152 of the lower slag package 15.

[0075] It can be understood that the first upper cutting knife 2132 and the second upper cutting knife 214 can be two independent cutting knives, or two discontinuous spaced cutting edges on the same cutting knife.

[0076] In a second aspect, please refer to again Figures 1 to 15 , an embodiment of the present invention provides a method for removing a double-layer slag package. This removal method is executed by the double-layer slag package removing device 200 described in any one of the above, and it includes the following steps:

[0077] The first step: Feed the workpiece 11 with the upper slag package 14 and the lower slag package 15 into the cutting station of the double-layer slag package removing device 200; In this embodiment, the workpiece 11 can be on a die that has just completed die-casting. The double-layer slag package removing device 200 moves to the corresponding position of the die-casting die to prepare for cutting the slag package.

[0078] In the second step, the driving assembly 23 drives the lower cutter assembly of the lower slag bag removal unit 22 to move along the first direction, so that the driving block 225 drives the lower cutter 224 to move along the second direction to cut off the lower slag bag 15. Specifically, the specific execution actions of this step are as follows: the driving module 232 is controlled to start, and the driving connecting plate 234 is pushed to move in the direction close to the lower slag bag 15 under the common guidance of the guide rod 233, the guide block 235 and the guide rail 236. The driving connecting plate 234 synchronously drives the lower connecting plate 223 to move toward the side close to the lower slag bag 15, and the lower connecting plate 223 first compresses the first elastic reset member 2232, and the first elastic reset member 2232 pushes the lower support plate 222 to move close to the lower slag bag 15. The slag bag 15 moves to one side until the buffer plate 227 abuts against the lower edge 13 of the workpiece 11, and the driving module 232 continues to move. At this time, the first elastic reset member 2232 is further compressed. At the same time, the lower connecting plate 223 drives the driving block 225 to move along the guide hole toward the side close to the lower slag bag 15, and the driving block 225 synchronously drives the lower cutting knife 224 to move vertically downward until the blade 2241 acts on the lower incision 17 and cuts off the lower slag bag 15 from the lower edge 13.

[0079] The third step is to control the upper slag bag removal unit 21 to descend, the clamping assembly 212 first clamps the workpiece 11, specifically the top surface of the upper edge portion 12 of the workpiece 11, and the upper cutter assembly 213 then cuts off the upper slag bag 14 from the workpiece 11. Specifically, the driving end of the driving unit is connected to the upper connecting plate 211. When the driving unit drives the upper connecting plate 211 to descend, the bottom of the upper clamping block 2121 is slightly lower than the cutting edge of the upper cutter assembly 213 in the initial state. Therefore, when descending, the bottom of the upper clamping block 2121 first contacts the upper edge portion 12 of the workpiece 11. When it continues to descend, the third elastic reset member 2123 is compressed. At this time, the upper clamping block 2121 is tightly attached to the upper edge portion 12 of the workpiece 11. When it continues to descend, the cutting edge of the upper cutter assembly 213 acts on the upper incision 16, and the upper slag bag 14 is cut off from the workpiece 11. The lower slag bag 15 is directly dropped and output from the bottom. When there is a part on the lower slag bag 15 that cannot be removed by the lower slag bag removal unit 22, the upper cutter assembly 213 can be synchronously driven to synchronously remove it. In the second step, when the lower slag bag removal unit 22 extends into the interval between the upper slag bag 14 and the lower slag bag 15, the abutting surface 2231 and the clamping surface 2221 on the top of the lower connecting plate 223 and the lower supporting plate 222 are respectively aligned with the bottom surface of the clamping assembly 212, and the top surface and the bottom surface of the upper edge portion 12 are respectively fitted and clamped, so as to avoid the workpiece 11 from being pulled when the upper slag bag 14 is removed.

[0080] Step 4: The driving component 23 drives the lower cutting tool component to reset in the reverse direction to form a clearance space, and the removed upper slag pocket 14 drops and outputs from the clearance space. Thereafter, the upper slag pocket removing unit 21 rises and resets to wait for the next slag pocket removing instruction.

[0081] The double-layer slag pocket removing device and its removing method in this embodiment integrate an upper slag pocket removing unit and a lower slag pocket removing unit, and adopt a matching structure of a driving block and an inclined surface of a lower cutting tool for the transmission structure inside the lower slag pocket removing unit, so as to realize the slag pocket cutting action in a small space between the upper slag pocket and the lower slag pocket. The upper slag pocket and the lower slag pocket are almost simultaneously and quickly removed, which not only simplifies the device structure, reduces the occupied space, but also improves the slag pocket removing process efficiency and the workpiece forming quality.

[0082] The above only further illustrates the technical content of the present invention with embodiments to make it easier for readers to understand, but it does not mean that the implementation manners of the present invention are limited to this. Any technical extension or re-creation made according to the present invention is protected by the present invention. The protection scope of the present invention is subject to the claims.
