[0035] It needs to be explained that the front clamping block 10 is close to the mold changing vehicle 3, and the connecting piece 12 can also limit the movement of the lower sub-mold frame 14 on the lower mold frame 1, that is, the lower sub-mold frame 14 will not be offset from the lower mold frame 1, and the inclined part of the front clamping block 10 can enable the lower sub-mold frame 14 to move stably between the front clamping block 10 and the rear clamping block 13. In addition, the lower sub-mold frame 14 and the upper sub-mold frame 15 are provided with holes that match the front clamping block 10 and the rear clamping block 13 to improve the clamping effect of the lower sub-mold frame 14 and the upper sub-mold frame 15.

[0037] The mounting part and the positioning part of the positioning member 16 can be driven hydraulically, which is a conventional method in the prior art, so as to facilitate the replacement of the lower mold 17 and the upper mold 18. In addition, the shape of the side of the lower mold 17 and the upper mold 18 close to each other is not limited, and the staff can make adjustments according to the situation.

[0038] Reference Figure 1-Figure 2The reversing guide mechanism includes a guide rail 4 symmetrically fixedly connected to the mold changing vehicle 3, a fixing piece 23 matching the guide rail 4 is symmetrically fixedly connected to the lower mold frame 1, and a plurality of groups of running wheels 32 are symmetrically arranged on one side of the lower mold frame 14 close to the fixing piece 23, wherein the size between the two groups of guide rails 4 matches the size of the lower mold frame 14, a groove matching the running wheel 32 is opened on the lower mold frame 14, the bottom of the running wheel 32 is located outside the lower mold frame 14, and a guide assembly is arranged on the fixing piece 23.

[0039] A baffle is also provided at one end of the mold changing cart 3 away from the lower mold frame 1 to prevent the lower sub-mold frame 14 to be replaced from falling off the mold changing cart 3. When moving the lower sub-mold frame 14, the lower sub-mold frame 14 can be moved along the guide rail 4 to the side of the lower mold frame 1 through the walking wheels 32, thereby realizing the replacement of the lower sub-mold frame 14 and converting the traditional mold changing sliding operation into a rolling mode, thereby reducing the wear of the lower sub-mold frame 14, reducing the load of mold changing, and also reducing the work intensity during mold changing and improving the working environment of mold changing operations.

[0040] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 The guide assembly includes a roller 27, a plurality of grooves 24 and wheel grooves 25 are provided inside the fixing member 23, the grooves 24 are connected to the wheel grooves 25 in the corresponding direction, a rotating shaft 26 is rotatably connected inside the grooves 24, the roller 27 is fixedly connected to the rotating shaft 26, and the roller 27 matches the wheel groove 25, wherein the wheel grooves 25 on the fixing members 23 on both sides are close to each other and the top is open, the roller 27 extends from the inside of the wheel groove 25 to the outside of the fixing member 23, the size between the rollers 27 on both sides matches the size of the lower sub-mold frame 14, and also includes a limiting tooth ring 31 fixedly connected to the rotating shaft 26, a side of the fixing member 23 close to the limiting tooth ring 31 is symmetrically provided with a transverse groove 28, a limiting hydraulic rod 29 is fixedly connected inside the transverse groove 28, and a limiting block 30 matching the limiting block 30 is fixedly connected to the output end of the limiting hydraulic rod 29, wherein the limiting hydraulic rod 29 is connected to the clamping drive member 11 through a pipeline.

[0041] When the lower mold frame 14 moves to the lower mold frame 1, the outer wall of the lower mold frame 14 will contact the roller 27, which can not only pneumatically guide the movement of the lower mold frame 14 to ensure the position accuracy of the lower mold frame 14 when it is replaced, but also reduce the wear of the outer wall of the lower mold frame 14. In addition, during the replacement process, the distance between the front clamping block 10 and the rear clamping block 13 is at the maximum value (greater than the size of the lower mold frame 14). After the lower mold frame 14 is moved, when the lower mold frame 14 is clamped by the front clamping block 10 and the rear clamping block 13, the limit hydraulic rod will be driven at the same time. 29 extends to one side of the rotating shaft 26. After the front clamping block 10 and the rear clamping block 13 complete the clamping of the lower sub-die frame 14, the limiting hydraulic rod 29 drives the limiting block 30 to engage with the limiting tooth ring 31, thereby locking the roller 27 to prevent the roller 27 from rotating due to vibration and the like during the forging process of the aluminum alloy, thereby reducing the wear between the roller 27 and the lower sub-die frame 14. When the lower sub-die frame 14 is disassembled, the limiting hydraulic rod 29 drives the limiting block 30 to disengage from the limiting tooth ring 31, and the roller 27 is in a free rotation state, so as to facilitate the removal of the lower sub-die frame 14.

[0042] Reference Figure 4 A lower heating plate 19 is arranged between the lower sub-mold frame 14 and the lower mold 17, an upper heating plate 20 is arranged between the upper sub-mold frame 15 and the upper mold 18, grooves matching the lower heating plate 19 and the upper heating plate 20 are opened between the lower sub-mold frame 14 and the lower mold 17 as well as between the upper sub-mold frame 15 and the upper mold 18, the lower heating plate 19 and the upper heating plate 20 are tightly fitted with the lower mold 17 and the upper mold 18 respectively, and the lower mold frame 1 and the upper mold frame 2 are respectively connected with a lower circulation cooling pipeline 21 and an upper circulation cooling pipeline 22, and the lower circulation cooling pipeline 21 and the upper circulation cooling pipeline 22 are respectively evenly distributed inside the lower mold frame 1 and the upper mold frame 2.

[0043] The lower heating plate 19 and the upper heating plate 20 are connected to the lower sub-mold frame 14 and the upper sub-mold frame 15 in a detachable manner. This is a conventional method in the prior art and is not elaborated on herein. When the lower mold 17 and the upper mold 18 are heated by the lower heating plate 19 and the upper heating plate 20, the lower mold 17 and the upper mold 18 can be preheated to avoid cracks in the aluminum alloy during forging. In addition, by cooling the mold frame through a circulating cooling pipe, the heat transfer of the high-temperature mold to the jacking mechanism and the clamping mechanism can be reduced, thereby cooling the hydraulic components and reducing the influence of high temperature on the operation of the hydraulic components, so as to achieve the purpose of protection.
