[0036] In some embodiments, the mold transfer system further includes: a track assembly 7 , which is used to guide the transport vehicle 1 .

[0037] In this embodiment, the track assembly 7 guides the transport vehicle 1 so that the transport vehicle 1 can accurately reach the designated position in each functional area, and can prevent the transport vehicle 1 from colliding with the mold in the functional area. In a specific embodiment, a sensor is provided on the track assembly 7 to monitor the position of the transport vehicle 1 in real time to ensure that the transport vehicle 1 completes the transfer of the mold along its preset path.

[0038] In some embodiments, the transport vehicle 1 includes an RGV mother vehicle 101 and at least one RGV sub-vehicle 102, the RGV sub-vehicle 102 is arranged on the RGV mother vehicle 101, and the track assembly 7 includes a main track 701 for guiding the RGV mother vehicle 101 and multiple sub-tracks 702 for guiding the RGV sub-vehicle 102, one end of the multiple sub-tracks 702 is connected to the main track 701, and the other end is respectively connected to multiple functional areas, and at least one placement position 6 is arranged on the part of the sub-track 702 located in the functional area.

[0039] In this embodiment, the RGV sub-carriage 102 is arranged on the RGV mother car 101, and the RGV mother car 101 drives the RGV sub-carriage 102 to move on the main track 701. The RGV sub-carriage 102 can move along the sub-track 702 to transfer the casting mold to multiple functional areas. The sub-track 702 is provided with at least one placement position 6 on the part of the functional area, which is convenient for the RGV sub-carriage 102 to place the casting mold on the placement position 6. In a specific embodiment, the height of the main track 701 is lower than the height of the multiple functional areas, and the sub-track 702 is the same as the height of the multiple functional areas, which is convenient for the RGV sub-carriage 102 to move from the RGV mother car 101 to the sub-track 702, and the RGV sub-carriage 102 transfers the casting mold to the placement position 6 in the functional area along the sub-track 702. In a more specific embodiment, the main track 701 is arranged horizontally between the multiple functional areas, and the sub-track 702 extends longitudinally into the multiple functional areas, which is convenient for the RGV sub-carriage 102 to transfer the casting mold between the multiple functional areas.

[0040] Combination Figure 5-7 As shown, in a specific embodiment, a sub-carriage platform 1011 is provided on the RGV mother car 101, the RGV sub-carriage 102 is placed on the sub-carriage platform 1011, a platform track 1012 is provided on the sub-carriage platform 1011, and the RGV sub-carriage 102 is movably provided on the platform track 1012. When the RGV mother car 101 moves to the sub-track 702, the platform track 1012 and the sub-track 702 are docked.

[0041] In this embodiment, the platform track 1012 and the sub-track 702 are connected, so that the RGV sub-car 102 can be smoothly transferred from the platform track 1012 to the sub-track 702, and then the casting mold can be transported to each functional area.

[0042] In some embodiments, the molding area 2 is arranged on one side of the main track 701 , and the other ends of multiple sub-tracks 702 are connected to the molding area 2 . The molding area 2 is provided with at least one loading position 201 for placing the mold, and the loading position 201 is connected to the other end of a sub-track 702 .

[0043] In this embodiment, the molding area 2 is used to mold the mold, and the mold is placed on the placement position of the molding area 2 through the RGV sub-trolley 102, and the mold to be poured is placed on the loading position 201. The RGV sub-trolley 102 transfers the mold on the loading position 201 to the pouring area 3, thereby completing the transfer of the mold from the molding area 2 to the pouring area 3.

[0044] In some embodiments, the pouring area 3 is disposed on both sides of one end of the main track 701 , and at least one sub-track 702 is disposed on both sides of one end of the main track 701 , and the other end of the sub-track 702 is connected to the pouring area 3 .

[0045] In this embodiment, the pouring area 3 is arranged on both sides of one end of the main track 701. The pouring areas 3 on both sides can pour the casting molds that need to be poured at the same time, which helps to improve the pouring efficiency of the casting mold, thereby improving the casting production efficiency of large castings.

[0046] In some embodiments, the heat preservation zone 4 is arranged on the other side of the main track 701 , and the other ends of the plurality of sub-tracks 702 are connected to the heat preservation zone 4 .

[0047] In this embodiment, the insulation area 4 and the molding area 2 are respectively arranged on both sides of the main track 701, which helps to distinguish and manage the functional areas, facilitates the transport vehicle 1 to transfer the casting mold between multiple functional areas, and helps to improve the casting production efficiency.

[0048] In some embodiments, the demolding area 5 is arranged on both sides of the other end of the main track 701 , and at least one sub-track 702 is respectively arranged on both sides of one end of the main track 701 , and the other end of the sub-track 702 is connected to the heat preservation area 4 .

[0049] In this embodiment, the mold release area 5 is used as the last process of the casting production. The mold release area 5 is set at the end of the main track 701, which is helpful to transfer the casting mold after the mold release process, avoid interference between the completed casting mold and the unfinished casting mold, and improve the production efficiency of the entire production process.

[0050] Combination Figure 1-3 As shown, in some embodiments, the mold transfer system further includes: a bottom carriage 8 and a placement rack 9, the bottom carriage 8 is used to place the mold; and two placement racks 9 are relatively arranged on the placement position 6 to support the bottom carriage 8.

[0051] In this embodiment, two placement racks 9 are relatively arranged on the placement position 6, which helps to support the bottom carriage 8. The mold is placed on the bottom carriage 8, which is convenient for the RGV sub-carriage 102 to take the mold from the placement position 6 to the RGV sub-carriage 102 and the RGV sub-carriage 102 to place the mold from the RGV sub-carriage 102 to the placement position 6. In a specific embodiment, the two placement racks 9 are relatively arranged on both sides of the sub-track 702, and the RGV sub-carriage 102 is provided with a lifting device (not shown), which is used to lift the mold from the placement rack 9, which helps to improve the transportation efficiency of the mold. In a more specific embodiment, the lifting device is driven by a cylinder for easy control.

[0052] Combination Figure 1-4 As shown, in the actual application scenario, the casting mold that needs to be transported is a sand box 12 with an outer contour size of 5600×3500×2000mm. The sand box 12 is mainly composed of a bottom box with box ribs, a cover box and a ring box without box ribs. The overall weight of the casting including the sand box 12, molding sand and castings in the mold is about 100-120t. Because the bottom of the sand box 12 is composed of box ribs and molding sand, the overall compressive strength is low. It can withstand surface support force but cannot withstand local point support force. Therefore, the sand box 12 after pouring cannot be transported by traditional lifting.

[0053] In order to prevent the casting from having problems such as collapse or falling of the bottom box sand of the sand box 12, leakage of the unsolidified molten iron, and collapse or falling of the bottom box sand after pouring during the transportation process, the casting mold needs to be placed on the bottom carriage 8 during the transportation process. The size of the bottom carriage 8 should be larger than the size of the casting mold. The outline size of the bottom carriage 8 is 5800×3550×250mm, and the weight is 20t. During the transportation process, the casting mold can be placed entirely on the bottom carriage 8. The side of the bottom carriage 8 in contact with the casting mold is a plane structure, so that the casting mold can fully contact the bottom carriage 8, provide sufficient support for the molding sand at the bottom of the casting mold, and prevent the bottom mold from cracking, collapsing, and collapsing under the action of the molten iron pressure in the mold. The side of the bottom carriage 8 that is not in contact with the casting mold adopts a rib plate frame structure, which maintains the structural strength of the bottom carriage 8 while reducing the overall weight. The bottom carriage 8 is provided with six support parts 801, and the support parts 801 are used to provide support force points for the bottom carriage 8 and the RGV sub-carriage 102 during the transportation process.

[0054] The load-bearing capacity of each rack 9 in the pouring area 3 must be above 150t, and the load-bearing capacity of each rack 9 in other functional areas must be no less than 80t, to prevent the mold from being damaged due to insufficient load-bearing capacity of the rack 9.

[0055] In some embodiments, the mold transfer system further includes: a dust hood 10 and a guide rail 11 , wherein the guide rail 11 is disposed above the pouring area 3 , and the dust hood 10 is movably disposed on the guide rail 11 .

[0056] In this embodiment, the dust hood 10 is used to collect smoke and exhaust gas generated by the mold during the pouring process. Discharging the smoke and exhaust gas after harmless treatment can reduce the pollution of the pouring smoke and exhaust gas to the workshop and the environment, thereby achieving green pouring. The dust hood 10 can be movably set on the guide rail 11 so that the collection range of the dust hood 10 covers the entire pouring area 3.

[0057] In actual application scenarios, in order to achieve zoning management of each functional area and keep the environment of each functional area clean and tidy, each functional area is partitioned by a partition wall (not shown) to achieve relative independence between the functional areas. Door openings are opened on the partition wall for the transport vehicle 1 to pass between the functional areas.

[0058] Combination Figure 8 As shown, the present invention further provides a mold transfer method including the mold transfer system as described above, comprising steps S100 to S400:

[0059] S100, when the mold needs to be shaped, the control host sends a command to the molding area 2 to shape the mold;

[0060] S200, when the mold needs to be poured, the control host sends a command to the transport vehicle 1 to transfer the mold to the pouring area 3, and sends a command to the pouring area 3 to pour the mold;

[0061] S300, when the mold needs to be kept warm, the control host sends a command to the transport vehicle 1 to transfer the mold to the warming area 4, and sends a command to the warming area 4 to keep the mold warm;

[0062] S400, when the mold needs to be de-molded, the control host sends a command to the transport vehicle 1 to transport the mold to the de-molding area 5, and sends a command to the de-molding area 5 to de-mold the mold.

[0063] In the embodiment of the present invention, the control host controls the transport vehicle 1 to transfer the mold in multiple functional areas in a timely manner, which solves the problem that the mold of existing large castings cannot be transferred out of the pouring area 3 in a short time during the casting production process, and improves the production efficiency of the casting production.

[0064] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0065] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
