Example 1

Referring to fig. 1, the present embodiment provides a polygonal pile forming mold 100, and the polygonal pile forming mold 100 includes an open mold body 3 and two or more modular mold plates 1. As shown in fig. 2, the open-type mold body 3 is provided with at least two notches 32 on at least one side mold plate 31 at intervals along the longitudinal direction, and the side mold plate 31 is provided with a combined type molding plate 1 at each notch 32; at least part of the split mold plate 1 is adjustable in position in the widthwise direction of the open mold body 3 with respect to the side mold plates 31.

In a use state, the combined type modeling plate 1 and the open type mould body 3 jointly form a mould inner cavity of a polygonal straight pile or a polygonal special-shaped pile, and the mould solves the problem that the polygonal straight pile mould and the polygonal special-shaped pile mould do not have universality on different pile types.

As shown in fig. 3, a polygonal pile forming mold is shown which comprises a section of a modular mold plate 1, wherein the modular mold plate 1 comprises more than two mold plates hinged in sequence in the longitudinal direction of a side mold plate 31, and the hinge can be achieved by rotating a latch 14. In the longitudinal direction, the modeling plates at the two ends of the combined modeling plate 1 are respectively jointed with the edges of the corresponding notches 32. In addition, a positioning stopper is provided on the outside of the open type mold body 3 in the cavity to fix the adjusted split type mold plate 1. Therefore, in the use process of the polygonal pile forming die as the polygonal straight pile die and the polygonal special-shaped pile die, the combined type modeling plate 1 can be connected to the edges of the corresponding notches 32 without gaps, so that the combined type modeling plate 1 and the open type die body 3 can provide a complete die cavity, slurry leakage caused by the existence of gaps in the connection part is avoided, and the polygonal straight pile and the polygonal special-shaped pile can be manufactured in the same die on the premise of ensuring the quality.

Further, referring to fig. 4 and 5, in two adjacent mold plates, a vertically through groove 120 is formed on one longitudinal end surface of each mold plate, the groove 120 is a first arc surface 121 with a hinge point as an origin near a groove wall of the molding cavity, a vertically continuous protrusion 110 is formed on one longitudinal end surface of the other mold plate, and the protrusion 110 has a second arc surface 111 matched with the first arc surface 121. Preferably, the cross-sectional shape of the groove 120 including the first arc surface 121 and the protrusion 110 including the second arc surface 111 is an olecranon shape, the olecranon shape is embodied as two arcs and the two arcs intersect at a point, and the olecranon-shaped protrusion 110 and the groove 120 enable the olecranon tip of the protrusion 110 to always abut against the groove wall of the groove 120 during the hinging and rotating process of the two adjacent molding plates, and no interference is generated during the rotating process. In the process of adjusting the state of the combined type modeling plate 1 from a non-linear state to a linear state, the olecranon tip of the protrusion 110 gradually rotates from the first arc surface 121 abutting against the groove 120 along the hinge point between the protrusion 110 and the groove 120 until the first arc surface 121 and the second arc surface 111 overlap, at this time, the protrusion 110 is completely accommodated in the groove 120, and at this time, the plate surfaces of the combined type modeling plate 1 forming the molding cavity are coplanar and have no gap. Under the arrangement, the slurry leakage problem of the combined type molding plate 1 in the polygonal special-shaped pile mold cavity composition can be effectively improved. In addition, when the olecranon tip of the protrusion 110 abuts against the first arc surface 121 of the groove 120 to form and the molding surfaces of the adjacent molding plates form a certain angle, the molding surfaces of the adjacent molding plates form smooth transition, and compared with the original right-angle transition surface, the second arc surface 111 reduces the contact area between the polygonal special-shaped pile and the mold cavity, thereby effectively reducing the mold drawing resistance.
