[0043] First, see Figure 1-Figure 3An embodiment of the present application provides a mold changing robot for a foam molding machine, comprising a mold trolley 1, a first conveying mechanism 2, a docking mechanism 3, and a second conveying mechanism 4. The mold trolley 1 is used to carry a mold 100. The first conveying mechanism 2 is arranged on the mold trolley 1, and the first conveying mechanism 2 can drive the mold trolley 1 to move to a docking position; the docking mechanism 3 is arranged on the mold trolley 1, and the docking mechanism 3 is used to dock the mold trolley 1 with a docking track 5; the second conveying mechanism 4 is arranged on the mold trolley 1, and the second conveying mechanism 4 can drive the mold 100 to move along the docking track 5, so that the mold 100 moves to the mold changing position.

[0044] The embodiment of the present application provides a mold changing robot for a foam molding machine, which moves a mold cart 1 to a docking position through a first conveying mechanism 2, and then docks the mold cart 1 with a docking track 5 through a docking mechanism 3, so that the mold cart 1 can enter the docking track 5, and finally drives the mold cart 1 to move to a mold changing position on the docking track 5 to replace the mold 100 through a second conveying mechanism 4, thereby greatly shortening the mold 100 replacement time, improving the mold changing efficiency of the foam molding machine, and further shortening the downtime of the foam molding machine, so that the production efficiency of the foam molding machine is greatly improved, and it can also improve the operation safety when replacing the mold and improve the working environment of the mold replacement.

[0045] The mold changing robot of the foam molding machine is a component of the foam molding machine. In the embodiment of the present application, the mold changing robot of the foam molding machine is used to replace the foam mold 100 of the foam molding machine, so that foams of different specifications can be produced by one foam molding machine. Of course, in addition to being applied to the field of foam molding technology, the mold changing robot in the embodiment of the present application can also be applied to other equipment or scenarios that require the mold 100 to be replaced. In the embodiment of the present application, this is not limited.

[0046] like Figure 1-Figure 3 As shown, in some embodiments, the mold vehicle 1 includes a mounting frame 11, a docking frame 12 and a mold mounting frame 13. The mounting frame 11 is slidably connected to the docking frame 12. The docking mechanism 3 can drive the docking frame 12 to move along the mounting frame 11 so that the docking frame 12 is docked with the docking track 5. The mold mounting frame 13 is used to carry the mold 100. The mold mounting frame 13 is slidably connected to the docking frame 12. The second conveying mechanism 4 can drive the mold mounting frame 13 to move along the docking frame 12 and the docking track 5 so that the mold mounting frame 13 moves to the mold changing position.

[0047] By setting the mounting frame 11 and the docking frame 12 as a sliding connection, the docking mechanism 3 and the first conveying mechanism 2 can be relatively independent, thereby avoiding interference with each other, and by setting the mounting frame 11 and the docking frame 12 as a sliding connection, the docking frame 12 can be easily docked with the docking rail 5, thereby greatly improving the docking efficiency.

[0048] In addition, by slidingly connecting the mold mounting frame 13 with the docking frame 12, the docking mechanism 3 and the second conveying mechanism 4 can be relatively independent, thereby avoiding interference with each other. Moreover, by slidingly connecting the mold mounting frame 13 with the docking frame 12, the mold 100 can be more easily brought into the mold changing position, thereby greatly improving the mold changing efficiency.

[0049] Specifically, in the embodiment of the present application, a first slide rail 111 is disposed on the top of the mounting frame 11, a first sliding seat 121 is disposed on the bottom of the docking frame 12, and the first slide rail 111 is slidably connected to the first sliding seat 121. In addition, a first docking rail 122 is also disposed on the top of the docking frame 12, and a second sliding seat 131 is disposed on the bottom of the mold mounting frame 13, and the second sliding seat 131 is slidably connected to the first docking rail 122.

[0050] In some embodiments, a second docking rail 51 is provided on the docking rail 5, and the docking mechanism 3 can drive the docking frame 12 to dock with the docking rail 5, so that the first docking rail 122 and the second docking rail 51 are docked, and the second sliding seat 131 can slide along the first docking rail 122 to the second docking rail 51, and then slide along the second docking rail 51 until the mold frame 13 reaches the mold changing position for mold changing.

[0051] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the docking mechanism 3 includes a first driving member 31, a docking gear 32 and a docking rack 33. The first driving member 31 is fixed on the mounting frame 11, the docking gear 32 is arranged on the output end of the first driving member 31, the docking rack 33 is fixed on the docking frame 12, the docking gear 32 is meshed with the docking rack 33, and the first driving member 31 can drive the docking gear 32 to drive the docking frame 12 to move relative to the mounting frame 11.

[0052] By fixing the docking rack 33 on the docking frame 12, and then driving the docking gear 32 through the first driving member 31 to drive the docking rack 33 to move, the docking frame 12 fixedly connected to the docking rack 33 moves to the docking position until the docking frame 12 docks with the docking track 5, so that the mold 100 can be accurately moved to the docking track 5, and then moved along the docking track 5 to the mold changing position for mold changing, thereby greatly improving the working accuracy of the mold changing robot of the entire foam molding machine.

[0053] like Figure 1-Figure 3 As shown, in some embodiments, the first conveying mechanism 2 includes a second driving member 21 and a moving component 22. The second driving member 21 is fixed on the mold cart 1, and the moving component 22 is arranged at the bottom of the mold cart 1. The second driving member 21 can drive the moving component 22 to move the mold cart 1 to the docking position.

[0054] Specifically, the moving component 22 includes a first chain 221, a first rotating shaft, a wheel 223, a second chain 224 and a second rotating shaft. A first gear is provided at the output end of the second driving member 21, and a second gear is also provided on the first wheel shaft 222. One end of the first chain 221 is meshed with the first gear, and the other end is meshed with the second gear. A third gear is also provided on the first wheel shaft 222, and a fourth gear is provided on the second wheel shaft 225. One end of the second chain 224 is meshed with the third gear, and the other end is meshed with the fourth gear. Wheels 223 are provided at both ends of the first wheel shaft 222 and the second wheel shaft 225.

[0055] like Figure 1 , Figure 3 and Figure 5 As shown, in some embodiments, the second conveying mechanism 4 includes a third driving member 41 and a docking assembly 42, the third driving member 41 is fixed on the docking frame 12, the docking assembly 42 is arranged on the docking frame 12, and the mold frame 13 is arranged on the docking assembly 42, and the third driving member 41 can drive the docking assembly 42 to drive the mold frame 13 to move along the docking frame 12 and the docking track 5, so that the mold frame 13 moves to the mold changing position.

[0056] Specifically, the docking assembly 42 includes a first push plate 421, a second push plate 422 and a mounting plate 423. The mold frame 13 is fixedly connected to the mounting plate 423. The third driving member 41 can drive the first push plate 421 to move to the mold changing position. The first push plate 421 is slidably connected to the second push plate 422. The second push plate 422 is slidably connected to the mounting plate 423. By arranging the first push plate 421, the second push plate 422 and the mounting plate 423, the moving range of the mold frame 13 can be greatly extended, thereby adapting to docking frames 12 of different lengths.

[0057] like Figure 1 , Figure 3 and Figure 6 As shown, in some embodiments, the mold changing robot of the foam molding machine further includes a first locking assembly 7 , which is disposed on the docking frame 12 , and is used to fix the relative position of the docking frame 12 and the mounting frame 11 .

[0058] By setting the first locking assembly 7, after the docking frame 12 is docked with the docking track 5, the relative positions of the docking frame 12 and the mounting frame 11 can be fixed, thereby preventing the docking frame 12 and the docking track 5 from loosening during the process of replacing the mold 100, or even causing the docking frame 12 to be disconnected from the docking track 5, thereby affecting the mold change.

[0059] Specifically, the first locking assembly includes a first mounting seat 71, a first connector 72 and a first handle 73. The first mounting seat 71 is fixed to the docking frame 12, and the first handle 73 is rotatably connected to the first mounting seat 71. By rotating the first handle 73, the first connector 72 can be inserted into the first plug hole opened on the mounting frame 11, thereby fixing the relative position of the docking frame 12 and the mounting frame 11.

[0060] like Figure 1 , Figure 3 and Figure 6 As shown, in some embodiments, the mold changing robot of the foam molding machine further includes a second locking assembly 8, which is disposed on the docking frame 12, and is used to fix the relative position of the mold mounting frame 13 and the docking frame 12.

[0061] By setting the second locking assembly 8 to fix the relative position of the mold frame 13 and the docking frame 12, it is possible to prevent the mold frame 13 and the docking frame 12 from sliding relative to each other during the process of the second conveying mechanism 4 conveying the mold frame 13, thereby causing the mold frame 13 to slide off the docking frame 12, thereby causing damage to the mold 100 and the mold frame 13.

[0062] Specifically, the second locking assembly includes a second mounting seat 81, a second connector 82 and a second handle 83. The second mounting seat 81 is fixed to the docking frame 12, and the second handle 83 is rotatably connected to the second mounting seat 81. By rotating the second handle 83, the second connector 82 can be inserted into the second connector hole opened on the mold frame 13, thereby fixing the relative position of the docking frame 12 and the mold frame 13.

[0063] like Figure 1-Figure 3 As shown, in some embodiments, the mold changing robot of the foam molding machine further includes a conveying track 6, and the first conveying mechanism 2 is slidably connected to the conveying track 6, and the first conveying mechanism 2 can drive the mold vehicle 1 to move to the docking position along the conveying track 6. One end of the conveying track 6 is a loading position for the mold 100, and the other end is a disassembly position for the mold 100.

[0064] By providing the conveying track 6 , the mold vehicle 1 can carry different molds 100 to the docking position, and then the mold 100 is conveyed to the mold changing position by the second conveying mechanism 4 , thereby greatly improving the mold changing efficiency.

[0065] In addition, in the embodiment of the present application, in order to save production costs, only one mold cart 1 is provided. Of course, in other embodiments, multiple mold carts 1 may be provided on the conveying track 6, and different mold carts 1 may be loaded with different molds 100.

[0066] like Figure 1-Figure 3As shown, in some embodiments, the conveying track 6 is arranged along a first direction, and the docking track 5 is arranged along a second direction, and the first direction and the second direction are perpendicular to each other.

[0067] By setting the conveying track 6 along the first direction and the docking track 5 along the second direction, the conveying process on the conveying track 6 will not interfere with the docking process on the docking track 5. For example, multiple docking tracks 5 and docking positions are set along the length direction of the conveying track 6, and multiple mold carts 1 can successively reach different docking positions along the conveying track 6 and dock with different docking tracks 5, and replace the mold 100, so as to avoid the conveying track 6 and the docking track 5 being set in the same direction, and the mold cart 1 needs to return to the starting position after replacing the mold 100. In addition, only one mold cart 1 can be set, otherwise the mold cart 1 will interfere with other mold carts 1 during the return process.

[0068] In the embodiment of the present application, the first direction is the direction of conveying the mold 100 , and the second direction is the docking direction.

[0069] In a second aspect, an embodiment of the present application provides a foam molding machine, including the mold changing robot of the above-mentioned foam molding machine.

[0070] In some embodiments, the foam molding machine further includes a frame, and the mold carrier 13 carrying the mold 100 to be replaced is transported to the frame by the mold vehicle 1, and the mold 100 is quickly locked on the frame, thereby greatly improving the efficiency of mold change.

[0071] In some embodiments, the foam molding machine further comprises a frame, and a mold carrier carrying the mold to be replaced is transported to the frame by a mold vehicle, and the mold is quickly locked on the frame, thereby greatly improving the efficiency of mold changing.

[0072] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
