As shown in fig. 1 to 8, the square pile mold 01 of the preferred embodiment includes an upper mold plate 6 and two opposed mold plate units 1, and the mold plate units 1 and the upper mold plate 6 surround to form a mold cavity 13. The upper template 6 is detachably connected with the two side templates 12, in the embodiment, one side of the upper template 6 is connected to one template unit 1 in a clamped mode, the other side of the upper template 6 is connected with the other template unit 1 through a connecting piece (such as a bolt), one side of the upper template 6 can be connected with the corresponding template unit 1 in a clamped mode firstly during assembly, then the other side of the upper template 6 is connected with the other template unit 1 through the bolt, and the disassembly can be achieved otherwise.

Wherein each template unit 1 includes die block board 11 and the side form 12 that is connected with die block board 11, and has contained angle α between the shaping face of die block board 11 and the shaping face of side form 12, this contained angle α is greater than 90, in order to make things convenient for the drawing of patterns, in addition, be equipped with the passageway 122 that is used for letting in steam in the side form 12, so need not to set up specially and evaporate the foster pond, practice thrift the cost, and can remove the mould to interim construction site, do not receive the place restriction, reduce the limitation of construction.

The mould of this embodiment is used for the shaping variable cross section square pile, so set up a plurality of liner plate groups 5 along its length direction interval in each template unit 1, the square pile cross-section of liner plate group department shaping is compared with the cross-sectional area of square pile other positions and is little to make the square pile shaping become the variable cross section. Each lining plate group 5 comprises a bottom lining plate 51 arranged on the bottom template 11 and a side lining plate 52 arranged on the side template 12, and the bottom lining plate 51 is formed by sequentially splicing a plurality of bottom lining plate units. The bottom lining plate 51 and the bottom template 11, the side lining plate 52 and the side template 12 can be connected in a clamping way, a screw joint way and the like, and can also be of an integral structure.

In this embodiment, each of the die plate units 1 can move along the width direction of the bottom die plate 11 under the driving of a driving mechanism 3 to make the two bottom die plates 11 butt or separate, and of course, one of the die plate units 1 can also move to realize the adjustment of the size of the die cavity 13. As the size of the mold cavity 13 changes, the bottom gusset elements may be added or subtracted to accommodate the size of the mold cavity 13 and the appropriately sized upper mold plate 6 may be replaced.

Under the state that two template units 1 break away from, there will be great space between two die plates 11, for preventing that the concrete from leaking to in this space, be equipped with the connecting plate 4 that can cover the clearance between the two between two die plates 11. In order to prevent the pumping pressure from bending the connecting plate and causing the pile shape to deform, the connecting plate 4 is arranged on the bottom formworks 11 of one of the formwork units 1, the opposite end faces of the bottom formworks 51 on the two bottom formworks 11 are provided with a clamping block 111 and a clamping groove 112 which can be clamped with each other, namely, the clamping block 111 is arranged on one bottom formwork 51, the clamping groove 112 is arranged on the other bottom formwork 51, the connecting plate 4 covers the clamping block 111 and the clamping groove 112, and the clamping block 111 and the clamping groove 112 can play a role in supporting the connecting plate 4.

For other molds for forming straight piles with the same cross-sectional size at each position, the fixture block 111 and the clamping groove can be directly arranged on the opposite end surfaces of the two bottom formworks 11, namely, the fixture block 111 is arranged on one bottom formwork 11, and the clamping groove 112 is arranged on the other bottom formwork 11.

Actuating mechanism 3 locates the outside of template unit 1, this actuating mechanism 3 includes the motor and the lead screw 32 that links to each other with motor drive, lead screw 32 extends along the length direction of die block board 11, threaded connection has the sliding plate 33 that links to each other with corresponding side form 12 on the lead screw 32, because when adopting single lead screw 32, the load that lead screw 32 bore is great, make lead screw 32 fracture easily, can steadily rotate at work in order to guarantee lead screw 32, so lead screw 32 can be formed by the concatenation of many lead screw units, link to each other through shaft coupling 36 between two adjacent lead screw units.

The slide plate 33 is provided with a first slide block 34, and the corresponding side mold plate 12 is provided with a second slide block 35 slidably connected to the first slide block 34, but the second slide block 35 may be provided on the bottom mold plate 11.
