[0035] Specifically, the transfer mechanism 24 includes a transfer track 241, a transfer trolley 242 and a pushing assembly 243. There are two transfer track 241, which are respectively connected end to end with the casting conveying track 21 and the cooling conveying track 22; there are two transfer trolleys 242, which are synchronously moved on the transfer track 241 to respectively receive and output the mold 23. The transfer trolley 242 is provided with a transition track 244 which can be respectively docked with the casting conveying track 21 and the cooling conveying track 22 and has the same cross-sectional shape; the pushing assembly 243 is arranged on one side of the transfer track 241 and is located at the input end of the casting conveying track 21 or the cooling conveying track 22, and can push the mold 23 on the transfer trolley 242 into the casting conveying track 21 or the cooling conveying track 22. The transfer trolley 242 moves synchronously on the transfer track 241 and is connected to both ends of the casting conveyor track 21 or the cooling conveyor track 22. The transfer trolley 242 at one end pushes the mold 23 on the transfer track 241 forward into the casting conveyor track 21 or the cooling conveyor track 22 through a pushing component. At the same time, the mold 23 at the end of the casting conveyor track 21 or the cooling conveyor track 22 is pushed onto the transport trolley at the other end. When the molten metal poured from the smelting furnace has completely flowed out, the mold 23 on the transfer track 241 is pushed forward by the pushing component to complete the output and replenishment of the mold 23 at the end of the casting conveyor track 21 or the cooling conveyor track 22.

[0036] Preferably, the casting conveying track 21 and the cooling conveying track 22 have an I-shaped cross section, including an upper leg portion 2a and a lower leg portion 2b located at upper and lower ends and protruding outward, and a waist portion 2c connected between the upper and lower legs 2b.

The bracket 271 is located on both sides of the casting conveying track 21 and the cooling conveying track 22, and extends vertically downward from the bottom of the moving seat 26 to the top of the conveying track. A horizontally extending rotating shaft 275 is formed between the brackets 271, and the action wheel 272 is rotatably set on the rotating shaft 275. An extension portion 276 extends downward from the bottom of the bracket 271. The bottom surface of the extension portion 276 is lower than the bottom surface of the upper leg 2a of the track and higher than the top surface of the lower leg 2b of the track. An auxiliary shaft 277 is extended inwardly on the opposite surface of the extension portion 276. The auxiliary wheel 273 is rotatably set on the auxiliary shaft 277 to contact the bottom surface of the upper leg 2a of the track. The two sides of the bracket 271 extend inwardly horizontally to form There is a mounting platform 278, on which a limiting shaft 279 is vertically arranged, and a limiting wheel 274 is rotatably arranged on the limiting shaft 279 to contact the left and right sides of the leg 2a on the transfer track. The movable seat 26 moves on the casting conveying track, the cooling conveying track 22 and the transition track 244 through the action wheel 272; the auxiliary wheel 273 and the action wheel 272 clamp the leg on the track between the two to ensure the stability of the transport mold 23 and avoid impact, and the distance between the auxiliary wheel 273 and the action wheel 272 is greater than the height of the upper leg, leaving space for the weighing device 6 to lift the movable seat 26 and the mold 23 upward for weighing; the limiting wheel 274 can prevent the movable seat 26 from being worn with the track due to the load perpendicular to the conveying direction;

[0038] The action wheel 272 is arranged on the bracket 271 and the bottom surface is movably arranged on the track to contact the top surface of the upper leg 2a; a pair of auxiliary wheels 273 are arranged on the bracket 271 and distributed on both sides of the track, and the auxiliary wheels 273 extend inward from the bracket to the position where the top surface contacts the bottom surface of the upper leg 2a;

[0039] A pair of limiting wheels 274 are provided, which can be rotatably arranged on the bracket 271 and the rotation axis is perpendicular to the bottom surface. The two limiting wheels 274 can contact the left and right sides of the upper leg 2a of the transition track 244 or the casting conveying track 21 or the cooling conveying track 22 respectively.

[0040] The casting conveying track 21 and the cooling conveying track 22 are inclined downward along the conveying direction, preferably at an angle of 1° to the horizontal ground, and the transfer track is arranged to be inclined upward along the direction of conveying the mold 23 and connected between the casting conveying track and the cooling conveying track 22. This can prevent the mold 23 from automatically sliding on the track and can also make it easier for the pushing component to push the mold 23.

[0041] The drainage device 3 includes a drainage plate 31 and a telescopic mechanism 32. The drainage plate 31 is arranged below the chute 1 and extends to the top of the next mold 23 in the direction opposite to the conveying direction of the mold 23, and the drainage plate 31 is arranged to be tilted downward in the direction opposite to the conveying direction of the mold 23; the telescopic mechanism 32 is connected to the drainage plate 31, and drives the drainage plate 31 to move back and forth in the direction perpendicular to the conveying direction of the mold 23 to block the outlet of the chute 1, so that the molten metal flows into the next mold 23. Compared with the method of intercepting the molten metal, the residence time of the molten metal in the chute 1 is shortened and it will not solidify in the chute, the chute will not be blocked, and frequent cleaning is not required. In addition, there is no need to repeatedly intercept the molten metal, and a large amount of oxidized slag will not be generated, further improving the product quality.

[0042] The demoulding device 4 is arranged on the cooling conveying track 22 to demould the cooled metal ingot. The end of the cooling conveying track 22 is connected to the transfer mechanism 24 to transport the demoulded empty mold 23 back to the casting conveying track. The demoulding device 4 includes a mold core 41, a gripping mechanism 42 and a pressing mechanism 43. Two mold cores 41 are provided, which are symmetrically placed in the mold 23; the gripping mechanism 42 is arranged at the end of the cooling conveying track 22 to separate the metal ingot from the mold 23; the pressing mechanism 43 is arranged behind the gripping mechanism 42 to press and discharge the mold core 41 from top to bottom. Specifically, the mold core 41 is a truncated cone with a diameter that gradually increases from top to bottom. Furthermore, it also includes an installation robot 44 that is arranged on one side of the transfer mechanism 24 to place the mold core 41 in the empty mold 23.

[0043] The trimming device 5 is connected to the demoulding device 4 to perform trimming and marking on the demoulding metal ingot. The trimming device includes two stations arranged in sequence along the conveying direction to trim the mold core hole and the periphery of the metal ingot respectively.

[0044] The waste ingot return conveying line 7 is arranged between the demoulding device 4 and the trimming device 5, and an image recognition mechanism is arranged at the front end to screen out unqualified metal ingots and convey them outward.

[0045] The finished product off-line conveyor line 8 is arranged at the rear end of the trimming device to convey the trimmed and marked metal ingots out of the assembly line.

[0046] The control system includes a weighing device 6 and a controller. The weighing device 6 is arranged under the casting conveying track at the casting station to measure the weight of the mold 23 at the casting station; the controller is respectively connected to the mold circulation conveying device 2 and the telescopic mechanism 32, and controls the operation of each component according to the signal feedback from the weighing device 6. The smelting furnace discharges the molten metal once, and the molten metal enters the mold 23 through the chute 1. The weight of the mold 23 is weighed by the weighing device 6 under the casting station. After the weight of the molten metal in the mold 23 meets the requirements, the mold circulation conveying device 2 is controlled to drive the mold 23 to move forward and the telescopic mechanism 32 is controlled to drive the guide plate 31 to extend to cover the outlet of the chute 1. At this time, the molten metal flows into the next mold 23 through the guide plate 31. After the residual molten metal is discharged, the guide plate 31 is controlled to be retracted, and the next mold 23 is driven to enter the casting station for the next dumping of the smelting furnace. The weight of the molten metal entering each mold 23 can be accurately controlled while the excess molten metal flows to the next mold 23 through the guide plate 31, so as to avoid the molten metal staying in the chute 1 for too long and to avoid the overflow of the molten metal, thereby saving materials and improving production efficiency.

[0047] When the assembly line is working, the mold 23 circulates in the assembly line, and the empty mold 23 is moved toward the casting conveying track 21 on the transfer track 241 by the transfer trolley 242, and the core 41 is placed in the mold 23 by the installation robot 44. When the transfer trolley 242 moves to the transition track 244 and is opposite to the casting conveying track 21, the push assembly 243 pushes the mold into the casting conveying track 21, and the above steps are repeated to sequentially convey the mold 23 to the casting conveying track 21. When the mold 23 on the casting conveying track 21 moves below the outlet of the chute 1 and is located above the weighing device 6, the smelting furnace pours the molten metal into the mold 23 through the chute 1, and the mass of the molten metal in the mold 23 is measured by the weighing device. When the requirement is met, the telescopic mechanism 32 is controlled to drive the guide plate 31 to extend to cover the through hole 12 of the chute 1, so that the excess molten metal flows backward into the next mold 23 through the guide plate. The mold 23 filled with molten metal is pushed by the rear mold 23 in sequence, and moves from the casting conveying track 21 to the transfer trolley 242, and is transferred to the front end of the cooling conveying track 22 by the transfer trolley 242, and is pushed into the cooling conveying track 22 by the push assembly 243. The mold 23 moves on the cooling conveying track 22 and is cooled by the spray pipe 28 arranged above. The cooled metal ingot moves to the end of the cooling conveying pipeline 22 with the mold 23, and passes through the demoulding device 4 so that the demoulding device 4 grabs the metal ingot through the mold core 41 and separates it from the mold 23 and then discharges the mold core 41. The metal ingot is demoulded and conveyed backward. The front end of the waste ingot recovery conveying line 7 is provided with an image recognition device to screen the metal ingots. The qualified metal ingots continue to be conveyed backward, and the unqualified metal ingots are sent back to the smelting furnace by the waste ingot recovery conveying line. The qualified metal ingots enter the trimming device 5, and the two stations trim the mold core hole and the surrounding of the metal ingot respectively and then mark them. Finally, the finished metal ingot is transported out of the production line by the finished product off-line conveyor line 8.

[0048] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of implementation of the present utility model. That is, equivalent changes and modifications made according to the scope of the patent application of the present utility model and the contents of the specification should still fall within the scope covered by the patent of the present utility model.
