By using first connecting molds 6 of different sizes, box girders of different sizes can be manufactured. When demolding is required, the two sets of first electric telescopic rods 8 are activated, pulling the first slider out of the second movable groove 10.

Secondly, four sets of second electric telescopic rods 14 are activated, pushing the second movable block left and right within the third movable groove 13 and advancing it into the fourth movable groove 16. By using second connecting molds 12 of different sizes, the size of the inner mold 11 can be adjusted. When demolding is required, the first electric telescopic rods 8 are activated... The second electric telescopic rod 14 pulls the second slider out of the fourth movable groove 16. At this time, the third electric telescopic rod 17 can be activated. The third telescopic rod forms a pulling force between the two sets of second connecting molds 12, thereby removing the two sets of second connecting molds 12, which facilitates the disassembly of the box girder inner mold 11. At the same time, the first fixed seat 18 and the second fixed seat 19 are fixedly connected to the bottom end of the second outer mold 4, and the third fixed seat 20 and the fourth fixed seat 21 are fixedly connected to the top end of the base 3.

When disassembling the mold, the two sets of second hydraulic telescopic rods 23 are activated first, and then the two sets of second hydraulic telescopic rods 23 are activated again, thereby realizing that the two sets of second outer molds 4 and the first outer mold 1 rotate at an angle, which facilitates the disassembly of both sides of the outer mold.
