The inner side of the lower end of the clamping plate 602 is provided with a slot as a clamping part; or, the lower end of the clamping plate 602 is C-shaped bent to serve as a clamping part.

[0033] This forms a limiting groove at the end of the pressure plate 7, thereby ensuring that the pressure plate 7 can be lifted when the displacement is upward.

[0034] In an optional embodiment, the dismantling station is located on the ground rail of the sleeper mold 3 (the ground rail is not shown in the figure). The sleeper mold 3 is equipped with rollers corresponding to the ground rail and is rotated by a traction device. Here, the power structure of the sleeper mold 3 is not subject to too many restrictions.

[0035] The dismantling station includes at least two portal-shaped support frames 4. The support frames 4 are set in the assembly slot in the middle of the ground rail. The columns at both ends are lifting cylinders. The lifting cylinders extend and retract to drive the support frames 4 to lift upward or retract below the ground rail. The dismantling station is equipped with a position sensor for the corresponding sleeper mold 3 to locate the position of the sleeper mold 3.
