Description

Technical Field

[0001] The invention relates to the technical field of gate separation, and in particular to a gate separation device for an aluminum die casting. Background Art

[0002] Gate separation in aluminum die casting refers to the process of separating the gate, the connection between the injection port and the main body of the casting, after casting is completed. The gate's function is to guide the molten aluminum into the various cavities of the mold, ensuring the casting is formed properly.

[0003] Patent publication number CN103464715A, published on December 25, 2013, discloses a tooling structure for separating gates of die-cast parts. The tooling structure includes a frame on which an electrical box and a hydraulic station are arranged. A cylinder is connected to the hydraulic station via a cylinder oil pipe. An ejection unit is installed on the frame and connected to the output end of the cylinder.

[0004] In the prior art including the above-mentioned patent, the main method for separating the gates of aluminum die-castings is to fix the cast aluminum die-castings with a tool and then cut them with a cutting machine. This method of fixing the aluminum die-castings with a tool and cutting the gates with a cutting machine can well fix the aluminum die-castings to avoid the problem of cutting offset caused by the loosening of the aluminum die-castings during cutting. In the current casting process of aluminum die-castings, in order to improve production efficiency, two aluminum die-castings are generally produced and cast simultaneously on a single casting template. The two cast aluminum die-castings are connected to each other. Therefore, in addition to manually cutting and separating the cast gates, it is also necessary to cut the connection between the two aluminum die-castings again. The currently common aluminum die-casting tooling and cutting machines can only separate the gates of the aluminum die-castings. The connection between the two aluminum die-castings needs to be manually cut off through secondary processing, which is cumbersome to operate. Moreover, the secondary processing and cutting still requires the two aluminum die-castings to be fixed with a tool. Summary of the Invention

DETAILED DESCRIPTION

[0040] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] like Figure 1-14 As shown, a gate separation device for aluminum die castings includes a band saw machine 1 equipped with a main saw blade 11, a guide frame 2 fixedly mounted on the band saw machine 1, and a fixed frame plate group sliding on the guide frame 2, the fixed frame plate group including:

[0042] The base plate 4 slides on the top of the guide plate frame 2 along the direction of the guide plate frame 2;

[0043] The movable plate 5 is hingedly mounted on the top of the base plate 4 and is kept perpendicular to the base plate 4. The movable plate 5 is provided with a main aluminum die casting consisting of a main gate 31, a main casting 3, a connecting rod 32, and an auxiliary casting 33. The connecting rod 32 is used to securely connect the main gate 31 and the auxiliary casting 33.

[0044] Clamping plates 7 are symmetrically hingedly arranged on the outer wall of one side of the movable plate 5, and the first ends of the two clamping plates 7 are close to each other to clamp the main casting 3;

[0045] The movable plate 5 is equipped to switch between the following two stations:

[0046] At station 1, the surface of the movable plate 5 and the guide plate frame 2 remain parallel, and the main saw blade 11 is located on the moving path of the connection between the main gate 31 and the main casting 3;

[0047] At the second workstation, the surface of the movable plate 5 and the guide plate frame 2 remain perpendicular, and the main saw blade 11 is located on the moving path of the connecting rod 32 .

[0048] Specifically, a support frame 12 is fixedly mounted on the band saw machine 1, and a guide frame 2 is fixedly mounted on the support frame 12. A slide groove 26 is formed on one side of the guide frame 2, and a main screw rod 15 is rotatably mounted in the slide groove 26. A main motor 14 is fixedly mounted in a protective cover 13 fixedly mounted on the top of the guide frame 2, and a first end of the main screw rod 15 is fixedly mounted on the output end of the main motor 14. A nut block 44 fixedly mounted on the base plate 4 is threadedly rotatably mounted on the main screw rod 15.

[0049] Furthermore, the movable plate 5 is fixedly mounted with a U-shaped protrusion 53 on one side of the main saw blade 11. The first ends of the two clamping plates 7 are provided with a rib 72. A limit plate 73 is fixedly mounted on one side of the two clamping plates 7 facing the U-shaped protrusion 53. A fixed plate 41 is fixedly mounted on the top of the base plate 4, and shielding plates 42 are symmetrically arranged on the fixed plate 41. By placing the main casting 3 of the main aluminum die-casting between the U-shaped protrusions 53 and affixing the main casting 3 to the U-shaped protrusions 53, and then driving the first ends of the two clamping plates 7 toward each other to clamp the main casting 3, the rib 72 and movable plate 5 limit the main casting 3 in position, while the limit plate 73 and U-shaped protrusion 53 further limit the main casting 3. The auxiliary casting 33 is affixed to the fixed plate 41 and is located between the two shielding plates 42, thereby limiting and shielding the auxiliary casting 3.

[0050] Then, the main motor 14 is started to drive the main screw 15 to rotate, thereby causing the nut block 44 to be threadedly rotated on the main screw 15 and drive the base plate 4 to slide on the top of the guide plate frame 2. At this time, the movable plate 5 on the base plate 4 is in the first station, and the plate surface of the movable plate 5 and the guide plate frame 2 remain parallel. Then, the movable plate 5 moves so that the connection between the main gate 31 and the main casting 3 is close to the main saw blade 11. By starting the main saw blade 11 to run, the connection between the main gate 31 and the main casting 3 is cut, and the main gate 31 is quickly separated from the main casting 3. Then, after the main casting 3 and the auxiliary casting 33 are a certain distance away from the main saw blade 11, the main motor 14 is stopped. Then, by driving the movable plate 5 to flip, the movable plate 5 is placed in the second station. At this time, the plate surface of the movable plate 5 and the guide plate frame 2 remain perpendicular, and the main saw blade 11 is located in the moving path of the connecting rod 32. Then the main motor 14 is started again to make the main motor 14 rotate in the opposite direction. At this time, the nut block 44 is threadedly rotated again on the main screw rod 15 and drives the base plate 4 to slide on the top of the guide plate frame 2 again to reset. At this time, as the base plate 4 moves, the connecting rod 32 on the movable plate 5 is close to the main saw blade 11, and then the main saw blade 11 is used to cut off the connecting rod 32. At this time, the main casting 3 and the auxiliary casting 33 are separated.

[0051] Therefore, by utilizing the movement of the base plate 4 to drive the movement of the main aluminum die casting on the movable plate 5, and cooperating with the clamping and fixing of the main casting 3 by the two clamping plates 7, the main gate 31 is separated from the main casting 3. Then, by flipping the movable plate 5 so that the main saw blade 11 is located in the moving path of the connecting rod 32, the main saw blade 11 is again used to cut the connecting rod 32, thereby separating the main casting 3 and the auxiliary casting 33. Therefore, compared with traditional cutting methods using clamps and cutting machines, by using the flipping of the movable plate 5 and the clamping of the clamping plates 7, in conjunction with the reciprocating movement of the movable plate 5, the cutting and separation of the main gate 31 and the separation of the two aluminum die castings, the main casting 3 and the auxiliary casting 33, can be achieved, thereby improving production efficiency.

[0052] Furthermore, the main saw blade 11 can be a double-sided toothed band saw blade. As the band saw machine 1 is an existing cutting device on the market, how it operates and how it is started and stopped is common knowledge among those skilled in the art and will not be described in detail here.

[0053] The movable plate 5 can be rotated by a motor; an electric push rod can be used in combination with a connecting rod; or any other method known to those skilled in the art can be used to drive the movable plate 5 to rotate.

[0054] The two splints 7 are synchronously flipped so that the first ends of the two splints 7 are brought close to each other to clamp the main casting 3. The driving method can be to use motors to drive them separately; or an electric push rod can be used in conjunction with a connecting rod to drive the two splints 7 to flip simultaneously; or any method known to those skilled in the art to drive the two splints 7 to flip synchronously can be used.

[0055] In the above technical solution, the base plate 4 is slid on the guide plate frame 2, and then after the two clamps 7 clamp the main casting 3 in the main aluminum die casting, the movable plate 5 moves with the base plate 4 to make the connection between the main gate 31 and the main casting 3 close to the main saw blade 11, and then the main saw blade 11 is used to separate the main gate 31 from the main casting 3, and at the same time, the movable plate 5 is driven to flip and the base plate 4 is moved again to make the connecting rod 32 on the movable plate 5 close to the main saw blade 11, and then the main saw blade 11 is used to cut the connecting rod 32 again, so that the main casting 3 and the auxiliary casting 33 are separated. Therefore, by the flipping of the movable plate 5, the clamping of the two clamps 7 and the reciprocating movement of the base plate 4, the main saw blade 11 is used to realize the separation of the main gate 31 and the separation of the main casting 3 and the auxiliary casting 33.

[0056] As an embodiment further provided by the present invention, the movable plate 5 is hingedly provided on the base plate 4 by a hinge shaft 51 provided thereon, and the hinge shaft 51 is provided with a torsion spring member 52 for switching the movable plate 5 from station one to station two. When the movable plate 5 is at station one, it maintains the same horizontal plane with the fixed plate 41 fixedly installed on the top of the base plate 4, and a locking unit for locking the movable plate 5 is provided on the fixed plate 41.

[0057] Specifically, the two ends of the torsion spring 52 are fixedly mounted on the movable plate 5 and the base plate 4 respectively. A blocking plate 43 is fixedly mounted on the top of the base plate 4. The locking unit is used to lock the movable plate 5 on the fixed plate 41. At this time, the movable plate 5 is in the working position, and the movable plate 5 and the fixed plate 41 maintain the same horizontal plane, and the torsion spring 52 deforms to store force.

[0058] Furthermore, when the movable plate 5 and the fixed plate 41 are maintained at the same horizontal plane, the main casting 3 of the main aluminum die casting is placed between the U-shaped protrusions 53 and fits against the U-shaped protrusions 53. Then, the first ends of the two clamping plates 7 are driven toward each other to clamp the main casting 3. Then, the main motor 14 is started to drive the main screw rod 15 to rotate, thereby causing the nut block 44 to be threadedly rotated on the main screw rod 15 and drive the base plate 4 to slide on the top of the guide plate frame 2. At this time, the movable plate 5 on the base plate 4 and the guide plate frame 2 remain parallel. Then, the movable plate 5 moves so that the connection between the main gate 31 and the main casting 3 is close to the main saw blade 11. By starting the main saw blade 11 to run, the connection between the main gate 31 and the main casting 3 is cut, thereby quickly separating the main gate 31 from the main casting 3. Then, after the main casting 3 and the auxiliary casting 33 are a certain distance away from the main saw blade 11, the main motor 14 is stopped. At this time, the locking unit is used to release the lock of the movable plate 5 on the fixed plate 41, and then the elastic stored force of the torsion spring 52 is released to allow the movable plate 5 to flip over, and the movable plate 5 flips over and fits on the blocking plate 43 and remains perpendicular to the fixed plate 41. The locking and releasing of the locking unit is then used to control the movable plate 5 and the fixed plate 41 to maintain the same horizontal plane and to control the flipping of the movable plate 5, so that when the movable plate 5 flips over, the connecting rod 32 can be cut close to the main saw blade 11 when the base plate 4 is restored.

[0059] The locking unit can be an electromagnet on the fixed plate 41 cooperating with the iron plate on the movable plate 5, which controls the magnetic attraction of the electromagnet to lock the movable plate 5 on the fixed plate 41, and releases the magnetic attraction to lock the movable plate 5, so that the torsion spring member 52 flips the movable plate 5; it can also be a locking rod flipped on the fixed plate 41, which is connected to the movable plate 5 to lock the movable plate 5 on the fixed plate 41, and then manually or motor-controlled to flip the locking rod to unlock the movable plate 5 from the fixed plate 41; or it can be any locking method known to those skilled in the art for locking and unlocking the movable plate 5 and the fixed plate 41.

[0060] As another embodiment provided by the present invention, the locking unit includes a buckle 45 fixedly mounted on the fixed plate 41 and a latch rod 56 slidingly arranged in the movable plate 5, and the buckle 45 is engaged with a latch hole 57 on the latch rod 56, and an extrusion rod 54 that moves synchronously with the latch rod 56 is slidingly provided on the outer wall of one side of the movable plate 5, and the extrusion rod 54 and the positioning plate 24 fixedly mounted on the top of the guide plate frame 2 are blocked and cooperated to slide.

[0061] Specifically, a hinged rod 55 is hinged on the card rod 56, and the first end of the hinged rod 55 is hinged to the first end of the extrusion rod 54. The outer wall of the positioning plate 24 on one side of the movable plate 5 is provided with an inclined surface 25. When the buckle 45 is engaged with the clamping hole 57 on the card rod 56, the movable plate 5 is locked on the fixed plate 41, and the movable plate 5 and the fixed plate 41 maintain the same horizontal plane. Then, by driving the movable plate 5 close to the positioning plate 24, the second end of the extrusion rod 54 begins to gradually squeeze on the inclined surface 25. At this time, the extrusion rod 54 and the positioning plate 24 are matched to each other, so that the extrusion rod 54 is squeezed and slides, and cooperates with the hinged rod 55 to drive the card rod 56 to slide. Then the card rod 56 slides and cooperates with the torsion spring member 52 to release the elastic force, so that the buckle 45 is unlocked and disengaged from the card rod 56. At this time, the movable plate 5 flips to drive the connecting rod 32 to swing.

[0062] By using the extrusion rod 54 and the positioning plate 24 to squeeze, combined with the elasticity of the torsion spring 52, the movable plate 5 can drive the main aluminum die-casting to move, allowing the main saw blade 11 to cut and separate the main gate 31. After that, the movable plate 5 is unlocked from the fixed plate 41 and flipped. Compared to using a motor or an electric push rod in conjunction with a connecting rod to control the flipping of the movable plate 5, the use of the extrusion rod 54 and the positioning plate 24 to block and release can save tedious steps such as the drive source and debugging.

[0063] As another embodiment provided by the present invention, a locking spring 58 is fixedly installed on the card rod 56. When the movable plate 5 is flipped and fitted onto the fixed plate 41, the buckle 45 is inserted into the card hole 57, and the locking spring 58 pushes the card rod 56 to lock the buckle 45 on the card rod 56.

[0064] Specifically, the two ends of the locking spring 58 are fixedly mounted on the card rod 56 and the movable plate 5 respectively. In the default state, the locking spring 58 pushes the card rod 56. Then, when the buckle 45 is inserted into the card hole 57, the locking spring 58 is used to push the card rod 56, so that the buckle 45 is locked on the card rod 56, thereby locking the movable plate 5 on the fixed plate 41.

[0065] Furthermore, when the movable plate 5 and the fixed plate 41 maintain the same horizontal plane, and the main casting 3 is clamped on the movable plate 5 by the two clamps 7, the movable plate 5 is driven close to the positioning plate 24, so that the second end of the extrusion rod 54 begins to gradually squeeze on the inclined surface 25. At this time, the extrusion rod 54 and the positioning plate 24 are matched to each other, so that the extrusion rod 54 is squeezed and slides, and cooperates with the hinge rod 55 to drive the card rod 56 to slide. At this time, the locking spring 58 is squeezed and deformed to accumulate force, and then the card rod 56 slides to cooperate with the torsion spring part 52 to release the elastic force, so that the buckle 45 is unlocked and disengaged from the card rod 56. At this time, the movable plate 5 flips to drive the connecting rod 32 to swing.

[0066] Furthermore, when the second end of the extrusion rod 54 is disengaged from the positioning plate 24, the locking spring 58 releases its accumulated force, thereby pushing the locking rod 56 back to its original position. After the base plate 4 is restored and the connecting rod 32 is cut close to the main saw blade 11, the movable plate 5 is manually flipped over. At this time, the buckle 45 is inserted into the locking hole 57 again, and then the elastic force of the locking spring 58 is combined to lock the movable plate 5 on the fixed plate 41 again and maintain the same horizontal plane with the fixed plate 41.

[0067] Therefore, by using the locking rod 56 in conjunction with the locking spring 58 to lock the buckle 45 and the sliding of the locking rod 56 in conjunction with the torsion spring 52 to release the stored force, it is possible to quickly switch between the two workstations of the movable plate 5 without using a driving source, thereby facilitating the cutting of the connecting rod 32 between the main gate 31 and the main casting 3 and the main casting 3 and the auxiliary casting 33, without the need for tedious processes such as changing tooling and electric control, thereby improving production efficiency.

[0068] As another embodiment provided by the present invention, it also includes a side plate 21 fixedly installed on the guide plate frame 2, and a reset plate 22 fixedly installed on one side of the side plate 21 is located on the path when the movable plate 5 is in the second working position.

[0069] Specifically, the buckle 45 is locked onto the latch rod 56, thereby locking the movable plate 5 onto the fixed plate 41. The movable plate 5 is now positioned at the workstation and maintained at the same level as the fixed plate 41. The main casting 3 of the main aluminum die casting is then placed between the U-shaped protrusions 53, affixing the main casting 3 to the U-shaped protrusions 53. The first ends of the two clamping plates 7 are then driven toward each other to clamp the main casting 3. The main motor 14 is then activated to rotate the main screw 15, thereby causing the nut block 44, which is threadedly mounted on the main screw 15, to rotate and drive the base plate 4 to slide on top of the guide plate frame 2. At this point, the movable plate 5 on the base plate 4 remains parallel to the guide plate frame 2. The movable plate 5 then moves so that the connection between the main gate 31 and the main casting 3 approaches the main saw blade 11. The main saw blade 11 is activated to cut the connection between the main gate 31 and the main casting 3, thereby quickly separating the main gate 31 from the main casting 3. Then, the base plate 4 is slid further so that the second end of the extrusion rod 54 on one side of the movable plate 5 begins to gradually press against the inclined surface 25. At this time, the extrusion rod 54 and the positioning plate 24 engage in a blocking manner, thereby causing the extrusion rod 54 to slide under compression, cooperating with the hinge rod 55 to drive the clamping rod 56 to slide. At this time, the locking spring 58 is squeezed and deformed to accumulate force, and then the clamping rod 56 slides and cooperates with the torsion spring 52 to release the elastic force, thereby unlocking the buckle 45 from the clamping rod 56. At this time, the movable plate 5 flips over to drive the connecting rod 32 to swing. The movable plate 5 then flips over and fits onto the blocking plate 43 and remains perpendicular to the fixed plate 41. At this time, the movable plate 5 is located at the second station and the main motor 14 stops rotating forward.

[0070] Furthermore, by restarting the main motor 14 to make the main motor 14 rotate in the opposite direction, the nut block 44 is again threadedly rotated on the main screw rod 15 and drives the base plate 4 to slide on the top of the guide plate frame 2 again to reset. At this time, as the base plate 4 moves, the connecting rod 32 on the movable plate 5 is close to the main saw blade 11, and then the main saw blade 11 is used to cut off the connecting rod 32. At this time, the main casting 3 and the auxiliary casting 33 are separated.

[0071] Furthermore, after the connecting rod 32 is cut by the main saw blade 11, as the base plate 4 continues to move, Figure 7 and Figure 8 and Figure 10 As shown, by using the end of the reset plate 22 to push the outer wall of the movable plate 5, the movable plate 5 is flipped again to approach the fixed plate 41. At the same time, the torsion spring 52 is deformed again to store force, and then the buckle 45 on the fixed plate 41 is inserted into the locking hole 57 again. Then, the elastic force of the locking spring 58 is cooperated to lock the movable plate 5 on the fixed plate 41 again and maintain the same horizontal plane with the fixed plate 41. In this way, the movable plate 5 is reset and switched from station 2 to station 1.

[0072] Therefore, the reciprocating movement of the substrate 4 is adopted, and the blocking and disassembly of the extrusion rod 54 and the positioning plate 24 and the blocking and disassembly of the reset plate 22 and the movable plate 5 are coordinated, so as to coordinate the elastic deformation and release process of the torsion spring 52 to realize the control of the flipping of the movable plate 5, and coordinate the locking and unlocking between the locking spring 58 and the buckle 45 and the clamping rod 56, so as to ensure the stability of the main aluminum die-casting during cutting. Compared with manual adjustment of cutting and switching of tooling or circuit control, the reciprocating movement of the substrate 4 and the flipping adjustment of the movable plate 5 are adopted, so that the main gate 31 on the main aluminum die-casting to be cut can be cut accurately and quickly.

[0073] As the optimal embodiment provided by the present invention, a pressure rod 6 and a symmetrically slidable shift rod 63 are slidably arranged in the movable plate 5, and the shift rod 63 and the pressure rod 6 are movably connected, and the pins 64 fixedly installed on the two shift rods 63 are respectively slidably arranged in the waist groove 71 opened at the second end of the splint 7.

[0074] Specifically, such as Figure 12 and Figure 13As shown, an auxiliary rod 62 is symmetrically hingedly provided on the pressure rod 6, and the first end of the auxiliary rod 62 is hingedly provided on the first end of the lever 63, and a latch 64 is fixedly mounted on the second end of the lever 63. Therefore, when the main casting 3 of the main aluminum die casting is placed between the U-shaped protrusions 53 and the main casting 3 is affixed to the U-shaped protrusions 53, the pressure rod 6 is driven to slide, and the auxiliary rod 62 cooperates to drive the lever 63 to slide. Then, the latch 64 slides in the waist groove 71 to flip the clamping plate 7. At this time, the first ends of the two clamping plates 7 are brought together to clamp the main casting 3. Then, the retaining edge 72 and the movable plate 5 are used to limit the main casting 3. At the same time, the limiting plate 73 and the U-shaped protrusion 53 further limit the main casting 3.

[0075] The flipping control and adjustment of the two clamping plates 7 are achieved by utilizing the sliding of the pressure rod 6 .

[0076] The compression rod 6 can be slid by a motor in conjunction with a gear and a rack; it can also be pushed by an electric push rod; or any other method known to those skilled in the art to drive the compression rod 6 to slide.

[0077] As another embodiment provided by the present invention, a collection box 8 and a blast block 81 located on both sides of the main saw blade 11 are provided on one side of the guide frame 2, and the main saw blade 11 is located on the blast path of the blast block 81 blowing air toward the collection box 8.

[0078] Specifically, the collection box 8 and the blast block 81 are respectively fixedly mounted on the support plate frame 12. The blast block 81 is provided with an air outlet 82 on the side facing the main saw blade 11. When the main saw blade 11 cuts the main gate 31 and the connecting rod 32, a large amount of metal waste will be generated. At this time, the cut waste will fall to the side of the blast block 81, and then the waste generated by the cutting will be blown into the collection box 8 by using the blast from the air outlet 82. In order to facilitate air circulation, a window is provided on the top of the collection box 8 that is connected to the collection chamber in the collection box 8. A filter is provided on the window, and when the blast block 81 blows air on the waste generated by the cutting of the main saw blade 11, the metal waste will be blown into the collection box 8, and the wind blown into the collection box 8 will be discharged along the filter, while the waste impurities will remain in the collection box 8.

[0079] The air outlet 82 on the blast block 81 may be blown by a blower and a ventilation pipe connected to the air outlet 82; or by a piston in conjunction with an electric push rod, etc., connected to the air outlet 82 through a piston cavity, thereby generating air blowing when the piston moves; or any method known to those skilled in the art to drive the air outlet 82 on the blast block 81 to blow air.

[0080] As another embodiment provided by the present invention, it also includes a sliding cavity connected to the air outlet 82 set on one side of the blast block 81 and a piston block 9 slidably set in the sliding cavity, and the piston block 9 and the base plate 4 move synchronously.

[0081] Specifically, such as Figure 4 As shown, a first piston chamber 17 and a second piston chamber 16 are provided on opposite sides of the sliding chamber, and the piston blocks 9 slide in the first piston chamber 17 and the second piston chamber 16 respectively. The first piston chamber 17 and the second piston chamber 16 are connected to the air outlet 82 respectively, and a first single air valve 91 is fixedly installed on the inner wall of one side of the first piston chamber 17, and a second single air valve 92 is fixedly installed on the inner wall of one side of the second piston chamber 16. The piston block 9 is fixedly mounted on the nut block 44. In the default state, the piston block 9 is located in the first piston chamber 17. Then, when the main motor 14 drives the main screw rod 15 to rotate, the nut block 44 is threadedly rotated on the main screw rod 15 and drives the base plate 4 to slide on the top of the guide plate frame 2. At this time, the two clamping plates 7 on the movable plate 5 clamp the main casting 3 and fix it. Then, the movable plate 5 approaches the main saw blade 11. At this time, the piston block 9 and the movable plate 5 keep moving synchronously, so that the piston block 9 moves from the first piston chamber 17 to the second piston chamber 16. At this time, the first single-vent valve 91 is opened to allow external air to enter the first piston chamber 17. At the same time, when the piston block 9 enters the second piston chamber 16 and compresses the second piston chamber 16, the second single-vent valve 92 is closed. At this time, the compressed gas in the second piston chamber 16 is discharged along the air outlet 82, thereby using the blast generated by compressing the second piston chamber 16 to blow away the waste chips generated by cutting the main gate 31. When the substrate 4 is reset, the piston block 9 moves from the second piston chamber 16 into the first piston chamber 17, and the second one-way air valve 92 opens to allow external air to enter the second piston chamber 16. Then, when the piston block 9 enters the first piston chamber 17 and compresses the first piston chamber 17, the first one-way air valve 91 closes. At this time, the compressed gas in the first piston chamber 17 is discharged again through the air outlet 82, thereby using the blast generated by compressing the first piston chamber 17 to blow away the waste chips generated by cutting the connecting rod 32. By using the piston block 9 to compress the second piston chamber 16 and the first piston chamber 17 as the substrate 4 moves, a portion of the waste chips generated by cutting are blown away and collected.

[0082] As another embodiment further provided by the present invention, a clamping spring 61 is provided on one side of the pressure rod 6 , and the clamping spring 61 pushes the pressure rod 6 so that the two shifting rods 63 respectively shift the clamping plates 7 to clamp the main casting 3 .

[0083] Specifically, the two ends of the clamping spring 61 are fixedly mounted on the pressure rod 6 and the movable plate 5 respectively. In the default state, the clamping spring 61 pushes the pressure rod 6. At this time, it cooperates with the auxiliary rod 62 to drive the lever 63 to slide, and then the pin 64 slides in the waist groove 71 to drive the splint 7 to flip. At this time, the first ends of the two splints 7 are close to each other to clamp the main casting 3.

[0084] Therefore, in order to quickly clamp the main casting 3 between the two clamps 7, the pressure rod 6 can be manually pushed to slide, and then the pressure rod 6 is used to squeeze the clamping spring 61. At this time, the pressure rod 6 slides to pull the two auxiliary rods 62, and then the auxiliary rod 62 drives the lever 63 to slide. At the same time, the pin 64 slides again in the waist groove 71 to push the clamp 7 to flip again. At this time, the first ends of the two clamps 7 move away from each other to release the clamping of the main casting 3.

[0085] Therefore, by manually pushing the pressure rod 6 and placing the main casting 3 on the movable plate 5, and then releasing the pressure rod 6, the first ends of the two clamping plates 7 are driven to move closer to each other to clamp the main casting 3 under the elastic reset action of the clamping spring 61, thereby achieving the effect of quickly clamping and fixing the main casting 3.

[0086] As an optimal embodiment further provided by the present invention, an insertion rod 23 is fixedly installed on the outer wall of one side of the side panel 21. When the reset plate 22 pushes the movable plate 5 to switch from station 2 to station 1, the insertion rod 23 is located on the moving path of the pressure rod 6.

[0087] Specifically, in the default state, the end of the reset plate 22 pushes against the outer wall of the movable plate 5, causing the torsion spring 52 to deform and store force, and the buckle 45 on the fixed plate 41 is inserted into the clamping hole 57, cooperating with the elastic force of the locking spring 58 to lock the movable plate 5 on the fixed plate 41 and maintain the same horizontal plane with the fixed plate 41. At this time, the movable plate 5 is in the first working position. At the same time, the end of the insertion rod 23 pushes and squeezes the pressure rod 6, and the pressure rod 6 squeezes the clamping spring 61 to deform and store force, and the pressure rod 6 pulls the two auxiliary rods 62 and slides the two levers 63 respectively. At the same time, the latch 64 slides again in the waist groove 71 to flip the splint 7 again. At this time, the first ends of the two splints 7 are away from each other.

[0088] Furthermore, by keeping the first ends of the two clamps 7 away from each other in the default state and locking the movable plate 5 on the fixed plate 41 , the main casting 3 in the main aluminum die casting can be placed between the U-shaped protrusions 53 and made to fit on the U-shaped protrusions 53 . Then, the main motor 14 is started to drive the main screw 15 to rotate, and the nut block 44 is threadedly rotated on the main screw 15 and drives the base plate 4 to slide on the top of the guide plate frame 2. At this time, the movable plate 5 on the base plate 4 and the guide plate frame 2 remain parallel, and then the movable plate 5 moves to make the connection between the main gate 31 and the main casting 3 close to the main saw blade 11. At the same time, because the base plate 4 slides close to the main saw blade 11, the insertion rod 23 gradually moves away from the pressure rod 6 and the extrusion on the pressure rod 6 is released. At this time, the pressure rod 6 is pushed again to slide and reset under the elastic reset of the clamping spring 61, and then the auxiliary rod 62 is cooperated to drive the lever 63 to slide, and the pin 64 slides in the waist groove 71 to flip the splint 7. At this time, the first ends of the two splints 7 are close to each other to clamp the main casting 3.

[0089] Furthermore, by starting the main saw blade 11, when the main casting 3 approaches the main saw blade 11, the main saw blade 11 is used to cut the connection between the main gate 31 and the main casting 3, thereby quickly separating the main gate 31 from the main casting 3. At the same time, the piston block 9 and the movable plate 5 move synchronously from the first piston chamber 17 to the second piston chamber 16. When the piston block 9 compresses the second piston chamber 16, the second single-vent valve 92 closes. At this time, the compressed gas in the second piston chamber 16 is discharged through the air outlet 82, so that the blast generated by the compression of the second piston chamber 16 is used to blow away the waste chips generated by cutting the main gate 31.

[0090] Then continue to slide the base plate 4 so that the second end of the extrusion rod 54 on one side of the movable plate 5 begins to gradually squeeze on the inclined surface 25. At this time, the extrusion rod 54 and the positioning plate 24 are matched to each other, so that the extrusion rod 54 is squeezed and slides, and cooperates with the hinge rod 55 to drive the card rod 56 to slide. At this time, the locking spring 58 is squeezed and deformed to store force, and then the card rod 56 slides and cooperates with the torsion spring part 52 to release the elastic force, so that the buckle 45 is unlocked and disengaged from the card rod 56. At this time, the movable plate 5 flips to drive the connecting rod 32 to swing, and the auxiliary casting 33 is disengaged from the fixed plate 41. Then the movable plate 5 flips and fits on the blocking plate 43 and remains perpendicular to the fixed plate 41. At this time, the movable plate 5 is located at station 2 and the main motor 14 stops rotating forward.

[0091] Furthermore, by restarting the main motor 14 to cause it to rotate in the reverse direction, the nut block 44 is again threadedly rotated on the main screw rod 15 and drives the base plate 4 to slide again on the top of the guide plate frame 2 to reset. At this time, as the base plate 4 moves, the connecting rod 32 on the movable plate 5 approaches the main saw blade 11, and then the main saw blade 11 is used to cut the connecting rod 32. At this time, the main casting 3 and the auxiliary casting 33 are separated. At the same time, during the reset of the base plate 4, the piston block 9 moves from the second piston chamber 16 to the first piston chamber 17. When the piston block 9 compresses the first piston chamber 17, the first single-vent valve 91 is closed. At this time, the compressed gas in the first piston chamber 17 is discharged again along the air outlet 82, so that the blast generated by the compression of the first piston chamber 17 is used to blow away the waste chips generated by cutting the connecting rod 32.

[0092] Furthermore, after the connecting rod 32 is cut by the main saw blade 11, as the base plate 4 continues to reset, Figure 7 and Figure 8 and Figure 10 As shown, by using the end of the reset plate 22 to push against the outer wall of the movable plate 5, the movable plate 5 is flipped again to approach the fixed plate 41. At the same time, the torsion spring 52 is deformed again to accumulate force, and then the buckle 45 on the fixed plate 41 is inserted into the latch hole 57 again. Then, the elastic force of the locking spring 58 is cooperated to lock the movable plate 5 on the fixed plate 41 again and maintain the same horizontal plane with the fixed plate 41. In this way, the movable plate 5 is reset and switched from station 2 to station 1. At the same time, the base plate 4 continues to slide closer to the side plate 21. At this time, because the reset plate 22 pushes the movable plate 5 to switch from station 2 to station 1, the insertion rod 23 is once again located in the moving path of the pressure rod 6. As the pressure rod 6 approaches and is squeezed by the insertion rod 23, the pressure rod 6 squeezes the clamping spring 61 again. At this time, the pressure rod 6 slides to pull the two auxiliary rods 62, and then the auxiliary rod 62 drives the lever 63 to slide. At the same time, the pin 64 slides again in the waist groove 71 to push the splint 7 to flip over again. At this time, the first ends of the two splints 7 move away from each other to release the clamping of the main casting 3. After the base plate 4 returns to the default state, the main motor 14 stops.

[0093] By sliding the base plate 4 back and forth on the guide plate frame 2, the movable plate 5 is locked, unlocked and flipped, and the clamping and releasing of the main casting 3 by the clamping plate 7, the main aluminum die-casting to be cut can be flipped along with the movable plate 5, and then the main gate 31 and the connecting rod 32 are cut to achieve the separation of the main gate 31 and the main casting 3, and the separation of the main casting 3 and the auxiliary casting 33. At the same time, it is convenient to quickly remove the main casting 3 from the movable plate 5. Compared with the traditional operation of using a cutting machine and tooling to clamp aluminum die-castings, the work of manually fixing and disassembling tooling during cutting is reduced, and the tediousness of manually adjusting the position of the aluminum die-casting for cutting at different positions is reduced. At the same time, a series of operations such as fast fixing and unlocking are achieved. These operations are achieved without the need for excessive programs and electrical controls, reducing tedious operations such as program debugging in electrical controls, thereby speeding up the production of aluminum die-castings.
