The switching rods 14 are movably arranged to penetrate through the cross plate 2. Two turning rods 13 are arranged on the switching seat 11 through a turning structure. Two lower dies 8 are fixedly installed at the ends of the turning rods 13 away from the switching seat 11. A first driving structure is arranged on the two switching rods 14. When the upper die 52 moves downwards and the aluminum alloy is die-cast in the lower die 8, the upper die 52 is removed from the lower die 8. At this time, the switching seat 11 can be moved in the cross plate 2 to move the lower die 8 filled with aluminum alloy out from below the upper die 52 for material taking. At the same time, another lower die 8 is driven to move and switch to below the upper die 52, so that die-casting work can continue in the other lower die 8, reasonably making use of the time of material taking to improve work efficiency;

[0033] The lifting structure includes two first fixing plates 3 installed on the processing table 1 at the front and rear sides of the cross plate 2. At both ends of each first fixing plate 3, vertical rods 4 are connected. At the tops of the vertical rods 4, a top plate 5 is installed.

When the hydraulic cylinder 6 is started to drive the lifting plate 7 to move up and down on the vertical rods 4, the upper die 52 can be driven to move up and down to carry out die-casting work.

[0034] See Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7, the flipping structure includes a first through groove 12 formed in the switching base 11. Two flipping rods 13 are rotatably inserted into the first through groove 12, and gears 53 are fixedly sleeved on one ends of the two flipping rods 13.

Teeth meshing with the gears 53 are arranged on the driving strip 16. One end of the driving strip 16 passing through the switching base 11 is connected with a driving block 17. First inserting rods 19 are connected to the lower ends of the mutually remote sides of the two driving blocks 17. A second fixing plate 18 is connected to the rear side of the cross plate 2 on the upper surface of the processing table 1. A first driving groove 20 is formed in the second fixing plate 18, and the left end of the first driving groove 20 is in a "Z" shape. A third fixing plate 21 is connected to the front side of the cross plate 2 on the upper surface of the processing table 1. A second driving groove 22 is formed in the third fixing plate 21, and the right end of the second driving groove 22 is in a "Z" shape. The two first inserting rods 19 are respectively inserted into the first driving groove 20 and the second driving groove 22. Collection frames 23 are installed on the left and right side surfaces of the processing table 1. When the switching base 11 moves rightward in the cross plate 2 and moves out the lower die 8 on the right side, the front first inserting rod 19 is driven to move to the right end of the second driving groove 22, so as to pull the corresponding driving strip 16 to move up and down in the switching base 11. The right flipping rod 13 is driven to rotate through the gear 53, and then the right lower die 8 is driven to flip, and the formed aluminum alloy in the lower die 8 is poured into the collection frame 23 for collection.

[0035] See Figures 1-8 , the first driving structure includes a connecting strip 24 connected to one end of the switching rod 14 passing through the cross plate 2.

[0036] The second driving structure includes a fixing strip 27 connected to the left side of the front surface of the lifting plate 7. A sixth fixing plate 30 is connected to the bottom end of the fixing strip 27. A second inserting rod 31 and a third inserting rod 32 are arranged on the sixth fixing plate 30 through a second switching structure. The second inserting rod 31 movably passes through the right end of the rear side surface of the sixth fixing plate 30. The third inserting rod 32 passes through the left end of the front side surface of the sixth fixing plate 30;

[0037] The second switching structure includes an inner groove 34 opened in the middle of the sixth fixing plate 30. A switching plate 35 is movably arranged in the inner groove 34. One ends of the second insertion rod 31 and the third insertion rod 32 are connected to the switching plate 35. A fifth driving groove 36 is opened in the middle of the switching plate 35. A first moving block 37 is tightly attached to the upper surface of the sixth fixing plate 30. A fourth insertion rod 38 is vertically fixed through the middle of the first moving block 37. The bottom end of the fourth insertion rod 38 is movably inserted into the fifth driving groove 36. A first electric telescopic rod 33 is installed on the right side of the upper surface of the sixth fixing plate 30. One end of the output shaft of the first electric telescopic rod 33 is connected to the first moving block 37. When the first electric telescopic rod 33 is started, it drives the fourth insertion rod 38 to move to the right end of the fifth driving groove 36, pushing the switching plate 35 to move towards the fourth fixing plate 25, so as to drive one end of the second insertion rod 31 to insert into the third driving groove 28 on the fourth fixing plate 25. At this time, when the lifting plate 7 drives the upper die 52 to move upward, by using the upward sliding of the second insertion rod 31 in the third driving groove 28, through the fourth fixing plate 25, the connecting strip 24 and the switching rod 14, the switching seat 11 is driven to move in the cross plate 2, so as to automatically switch between the two lower dies 8;

[0038] The feeding structure includes a mounting plate 40 welded to the rear side of the processing table 1 near one of the lower dies 8. A feeding plate 39 is installed on the mounting plate 40. A second through groove 42 is opened near the middle of the feeding plate 39. Shielding edges 41 are arranged at the upper and lower positions on the left and right side surfaces of the feeding plate 39. Second grooves 44 are opened on both left and right side surfaces of the second through groove 42. Second moving blocks 45 are slidably arranged in the second grooves 44. Two vertical grooves 46 are opened on one side surface of each second moving block 45. Lifting blocks are slidably arranged in the vertical grooves 46. Clamping blocks 47 are installed on the lifting blocks. Springs 48 are connected between the lifting blocks and the groove walls at one ends of the vertical grooves 46. Second electric telescopic rods 43 are installed at both ends of the rear side surface of the feeding plate 39. One ends of the output shafts of the second electric telescopic rods 43 are connected to the second moving blocks 45. L-shaped rods 49 are connected to the mutually remote side surfaces of each group of two clamping blocks 47. Rollers 50 are installed at one ends of the L-shaped rods 49. Guide plates 51 are arranged at the upper and lower positions on one side surface of the shielding edge 41. The guide plates 51 are in the shape of a parallelogram. After a feeding plate is placed on the feeding plate 39, the second electric telescopic rods 43 can be started to drive the second moving blocks 45 to move back and forth. With the elastic force of the springs 48, the rollers 50 can be driven to roll tightly along the side surfaces of the guide plates 51. When the second moving blocks 45 move towards the lower die 8, the two clamping blocks 47 can move towards each other. The two clamping blocks 47 are clamped to the feeding plate, and the feeding plate can be pushed towards the lower die 8, so as to convey the container filled with aluminum alloy liquid placed on the feeding plate towards the lower die 8. In this way, it is convenient for the staff to pour the aluminum alloy liquid into the lower die 8 for die-casting work.

[0039] The implementation principle of a die-casting forming device for aluminum alloy processing in an embodiment of the present invention is as follows: First, start the hydraulic cylinder 6 to drive the lifting plate 7 and the upper die 52 to move downward on the vertical rod 4 in the direction of the lower die 8. At this time, the second insertion rod 31 and the third insertion rod 32 are both in a state of disengaging from the third driving groove 28 and the fourth driving groove 29. As the upper die 52 continues to move, in the lower die 8, the die-casting work of aluminum alloy is carried out. During the die-casting process, start the first electric telescopic rod 33 to drive the fourth insertion rod 38 on the first moving block 37 to move leftward in the fifth driving groove 36 of the switching plate 35. By the extrusion of the fourth insertion rod 38 against the groove wall of the fifth driving groove 36, the switching plate 35 is pushed to move toward the side close to the fifth fixing plate 26 in the sixth fixing plate 30, thereby driving the third insertion rod 32 to insert into the bottom end in the fourth driving groove 29. Then, the hydraulic cylinder 6 drives the lifting plate 7 and the upper die 52 to move upward as a whole, driving the third insertion rod 32 to move upward in the fourth driving groove 29. By the extrusion of the third insertion rod 32 against the groove wall of the fourth driving groove 29, the fifth fixing plate 26 is pushed to move leftward, thereby driving the switching seat 11 to move leftward in the cross plate 2, moving the lower die 8 with the formed part out of the processing table 1. At the same time, another lower die 8 is driven to move and switch to directly below the upper die 52, so that the die-casting work can continue in another lower die 8. Moreover, the movement of the switching seat 11 drives the two first insertion rods 19 to move. When one of the first insertion rods 19 slides in the second driving groove 22, it drives the corresponding driving strip 16 to move upward, driving the corresponding flipping rod 13 to rotate through the corresponding gear 53, so that the lower die 8 switched to directly below the upper die 52 can be automatically turned upward. At the same time, the other first insertion rod 19 slides in the first driving groove 20, pulling the corresponding driving strip 16 to move downward, pulling the corresponding flipping rod 13 to rotate through the corresponding gear 53, thereby flipping the lower die 8 with the formed aluminum alloy to automatically pour the formed aluminum alloy into the collection box 23 for collection, realizing the automatic blanking work, which is time-saving and labor-saving, and greatly improves the work efficiency.

[0040] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
