[0023] <Embodiment One>
[0024] As Figure 1As shown, the dovetail side mold of the hollow web sheet pile provided by the embodiment comprises a lower mold 31, a middle mold 32 and an upper mold 33 arranged from bottom to top, and the materials of the molds are hard material such as stainless steel, high manganese steel and the like. The lower mold 31 and the middle mold 32 have a first contact surface 10, and the middle mold 32 and the upper mold 33 have a second contact surface 20. The first and second contact surfaces are arranged obliquely relative to the horizontal plane. The lower mold 31 comprises a first extension part 311 and a first main body 312, and a first forming groove 313 is formed between the first extension part 311 and the first main body 312. The upper mold 33 comprises a second extension part 331 and a second main body 332, and a second forming groove 333 is formed between the second extension part 331 and the second main body 332. The first extension part 311, the second extension part 331 and the middle mold 32 form a tenon structure 30 corresponding to the dovetail. In the above technical solution, the lower mold 31, the middle mold 32 and the upper mold 33 of the side mold are assembled from bottom to top in sequence. After assembly, the size and shape of the dovetail structure part of the produced sheet pile are controllable, and unevenness does not occur. Due to the oblique arrangement of the first and second contact surfaces, the middle mold 32 can be easily pulled out from left to right during demolding. After the middle mold is pulled out from left to right, the upper mold 33 will slowly descend from top to bottom under the action of its own gravity, and it is very easy to demold. Moreover, it will not cause damage to the upper dovetail groove structure from left demolding in the prior art. After the upper mold 33 falls down, it is completely separated from the sheet pile by lifting equipment from left to right for a distance, and then it is lifted to the mold storage area again. For the lower mold, it is lifted upward by lifting equipment to separate it from the dovetail, and then it is moved to the mold plate storage area from left to right, so that the demolding is completed. The dovetail produced in this way has a complete structure, a smooth surface, a standard size and can fully meet the high-precision construction. In the embodiment, a plurality of lifting rings for lifting are arranged at the positions close to the upper edges of the lower mold 31, the middle mold 32 and the upper mold 33, so that the mold can be easily disassembled.
[0025] In the embodiment, the lower surface of the first extension part is inclined downward from the right side to the left side at an angle of 10°-45°, and the upper surface of the second extension part is inclined downward from left to right at an angle of 10°-45°, so that the formed dovetail is in the shape of a dovetail groove. The first contact surface 10 is inclined downward from the inside to the outside of the side mold, the second contact surface 20 is inclined upward from the inside to the outside of the side mold, and the width of the middle mold 32 gradually increases from the inside to the outside of the side mold, so that when the middle mold is pulled out to the right side, the resistance of the upper and lower molds to it is reduced. Specifically, the upper mold 31 and the lower mold 33 are both in the shape of "7" and are symmetrically arranged, and the middle mold 32 is in the shape of a trapezoid, so that the mold is more convenient to process and assemble.
[0026] In the embodiment, the lower mold 33, the middle mold 32 and the upper mold 31 are provided with corresponding through holes 40, and locking members 41 are arranged in the through holes 40 to connect the molds in series into a whole. The lower mold 33 is vertically arranged on the bottom plate 1.

[0030] In this embodiment, the middle die 32 is provided with a bearing part 37, and the middle die 32 slides into the bearing part 37 when it is demoulded, thereby facilitating support.
[0031] In this embodiment, the bearing part 37 has a downwardly inclined guide surface 371, and the end of the guide surface 371 away from the middle die is provided with a stopper 372, thereby facilitating support and placement of the middle part of the mortise structure when it is pulled out to the right side.
[0032] Further, the bearing part 37 is arranged on the sliding part 36, and the bearing part 37 is away from or close to the side die along the sliding part 36. The sliding part 36 can be a sliding rail or a sliding groove or other existing sliding structure.
