[0095] When the fixed device needs to be driven to move vertically, the second electric push rod 21 is adjusted, the output end of the second electric push rod 21 can push the rack 20 to move vertically upward, the rack 20 can drive the first gear 19 to rotate; the first gear 19 drives the rotating rod 18 to rotate at the same time, the rotating rod 18 can drive the moving piece 17 to move vertically downward through the sliding between the sliding groove and the cylindrical pin, the moving piece 17 drives the sliding piece 15 to move synchronously, the sliding piece 15 moves under the limitation of the sliding block 16 and drives the connecting plate 14 to move, the connecting plate 14 drives the fixed device to move downward, after the fixed device fixes the casting, the second electric push rod 21 is adjusted reversely, so as to drive the fixed device and the casting to move vertically upward, which prevents the casting from touching the mold during the process of demolding and carrying, and avoids scratches on the surface of the casting.

[0096] As shown in Figure 6 and Figure 7 , the fixed device comprises a hollow cylinder 10, a plurality of suction cups 11, a piston piece 12 and a first electric push rod 13.

[0097] Specifically, the hollow cylinder 10 is arranged below the connecting plate 14 and is fixedly connected with the connecting plate 14; the plurality of suction cups 11 are arranged below the hollow cylinder 10 and are in communication with the hollow cylinder 10.

[0099] The piston piece 12 is arranged in the interior of the hollow cylinder 10, and the edge of the piston piece 12 is in close contact with the inner wall of the hollow cylinder 10.

[0100] In this embodiment, when the piston piece 12 moves vertically upward, the air in the suction cup 11 is sucked out, so as to fix the casting, and when the piston piece 12 moves vertically downward, air is blown into the suction cup 11, so as to release the fixing of the casting.

[0104] As shown in Figure 8 andFigure 9 As shown in the drawings, the spraying assembly comprises a liquid storage tank 22, a connecting pipe 23 and a spray head 24.

[0105] The liquid storage tank 22 is arranged above the connecting plate 14 and away from the hollow cylinder 10.

[0106] In this embodiment, the solution contained in the liquid storage tank 22 is a specific solution in the art, which can be a release agent or other solution, as long as it can satisfy the functions of cooling the castings and improving the release efficiency of the castings.

[0107] One end of the connecting pipe 23 is in communication with the liquid storage tank 22; the spray head 24 is arranged at the other end of the connecting pipe 23 and is in communication with the connecting pipe 23.

[0108] In this embodiment, the spray head 24 is an atomizing spray head, and its structure is consistent with that of the atomizing spray head commonly seen on the market; the solution in the liquid storage tank 22 is sent to the spray head 24 through the connecting pipe 23 and is sprayed out in the form of atomization.

[0109] The connecting pipe 23 is composed of a hose and two groups of hard pipes, and the two ends of the hose are in communication with one end of each group of hard pipes.

[0110] In this embodiment, the hard pipes located below can be bent along the position of the hose.

[0111] During spraying, the solution sprayed out of the spray head 24 spreads outward in a circular shape, resulting in less solution at the positions and more solution in the middle, and uneven spraying.

[0112] To solve the above problems, an embodiment is provided, and the die-casting industrial robot further comprises an auxiliary spraying device; the auxiliary spraying device is connected with the connecting pipe 23 and is used for rotating the spray head 24 horizontally.

[0113] As shown in the drawings, Figure 8 and Figure 9 The auxiliary spraying device comprises a second gear 25, a support 26, a third gear 27 and a stepping motor 28.

[0114] Specifically, the second gear 25 is internally provided with a notch, the connecting pipe 23 is arranged in the notch, and the second gear 25 is slidably connected with the connecting pipe 23 through the notch.

[0115] In this embodiment, when the second gear 25 rotates, an external force is applied to the hard pipes below, so that the connecting pipe 23 deflects along the position of the hose; since the second gear 25 and the connecting pipe 23 are not in a fixed relationship, the connecting pipe 23 will not rotate, thereby avoiding the connecting pipe 23 from being wound together.

[0116] The upper and lower end faces of the second gear 25 are provided with annular slides; the support 26 is internally provided with two groups of support blocks, which are arranged in the annular slides and are in sliding connection with the second gear 25 through the annular slides.

[0119] In the embodiment, the model of the stepping motor 28 is selected according to actual requirements, and the working conditions are met; the output end of the stepping motor 28 drives the third gear 27 to rotate; the third gear 27 simultaneously drives the second gear 25 to rotate.

[0120] Before spraying, the stepping motor 28 is started, the output end of the stepping motor 28 drives the third gear 27 to rotate, and the third gear 27 simultaneously drives the second gear 25 to rotate; the second gear 25 will make the connecting pipe 23 bend along the position of the hose through the sliding between the connecting pipe 23 and the hose, so that the spray head 24 revolves around the central axis of the upper hard pipe, improves the spraying range of the spray head 24, and makes the spraying more uniform.

[0121] As shown in Figure 1 the die-casting assembly comprises a die-casting lower die 2, a die-casting upper die 3 and a hydraulic cylinder 4.

[0123] In the embodiment, the model of the hydraulic cylinder 4 is selected according to actual requirements, and the working conditions are met.

[0124] The inner diameter of the die-casting lower die 2 is the same as the outer diameter of the die-casting upper die 3.

[0125] Working principle:

[0126] When the die-casting industrial robot is used, after the die-casting is completed, the die-casting upper die 3 and the die-casting lower die 2 are separated by adjusting the hydraulic cylinder 4, and the fixing device is moved to between the die-casting upper die 3 and the die-casting lower die 2 by the three-axis driving assembly and is horizontal to the casting.

[0127] Subsequently, by rotating the driving assembly 9, the position of the fixing device and the spraying assembly can be changed, and the stepping motor 28 is started, and the output end of the stepping motor 28 drives the third gear 27 to rotate, and the third gear 27 drives the second gear 25 to rotate at the same time; the second gear 25 will make the connecting pipe 23 bend along the position of the hose through the sliding between the connecting pipe 23 and the hose, so that the spray head 24 revolves around the central axis of the upper hard pipe, improves the spraying range of the spray head 24, and makes the spraying more uniform.

[0128] Then, the second electric push rod 21 is adjusted, the output end of the second electric push rod 21 can push the rack 20 to move vertically upwards, and the rack 20 drives the first gear 19 to rotate; the first gear 19 drives the rotating rod 18 to rotate at the same time, and the rotating rod 18 drives the moving piece 17 to move vertically downwards through the sliding between the sliding groove and the cylindrical pin; the moving piece 17 drives the sliding piece 15 to move synchronously, the sliding piece 15 moves under the limitation of the sliding block 16, and drives the connecting plate 14 to move, and the connecting plate 14 drives the fixing device to move downwards.

[0129] After the suction cup 11 contacts the casting, the first electric push rod 13 is adjusted, so that the output end of the first electric push rod 13 retracts, and drives the piston piece 12 to move vertically upwards at the same time; the piston piece 12 will suck the air in the suction cup 11 into the hollow cylinder 10, so that the suction cup 11 holds the casting, and the fixing of the casting is completed, and it is not necessary to rely on the ejection equipment to eject the casting from the mold first, so that the cost is saved.

[0130] After the casting is fixed by the fixing device, the second electric push rod 21 is adjusted in reverse, so as to drive the fixing device and the casting to move vertically upwards, prevent the casting from touching the mold in the demolding and carrying process, avoid scratches on the surface of the casting, and complete the use of the device this time.
