Background

Because of the appearance characteristics of the I-shaped pile, the H-shaped pile comprises two flanges and a web plate for connecting the two flanges, the left side and the right side of the pile body are provided with groove parts, in order to enable the H-shaped concrete pile to be demolded smoothly, the existing mould has two demolding modes, one is a side template overturning demolding mode, and the other is a side template lateral moving demolding mode. The I-shaped piles are combined by a rib and groove matching structure between flanges. The width of the flange is narrow, so that the transverse sizes of the ribs and the slots on the flange are smaller, the requirement on the accuracy of the die is high, and the ribs and the slots are easy to damage in the demolding process. Moreover, when piling, the convex ribs and the slots with small cross sections are very difficult to match, in practice, the convex ribs and the slots are often not very matched together, so that the tightness of splicing between piles is poor, and the convex ribs and the slots are very high in production precision requirement and construction requirement of the piles. The utility model of China patent with the publication number of CN201310673526.1 (with the publication number of CN 103707413A) discloses a side template turnover demoulding structure, which comprises at least one (more than one are connected in series), mould units (one mould unit completes the preparation of a support pile), each mould unit comprises a lower template, a left template and a right template hinged with the lower template to form an H-shaped support pile cavity, an oil cylinder connected with the left template and the right template, one end of the oil cylinder is hinged on a base, and the left template, the right template and the lower template jointly enclose a cavity matched with the appearance of the H-shaped concrete pile.

The utility model also discloses a side template lateral movement demoulding structure as disclosed in Chinese patent application No. CN201410211081.X (publication No. CN 103950094A), wherein the side template lateral movement demoulding structure comprises a mould underframe, a left template seat, a right template seat and a lower template, and a plurality of convex edges are arranged on the left template seat; the right template seat is provided with a plurality of grooves; the lower template is provided with a plurality of protruding blocks; the left template seat and the right template seat are respectively connected to the left side and the right side of the die underframe through a left moving device and a right moving device; the lower template is connected to the die underframe through a lifting device and is positioned between the left template seat and the right template seat; the bottoms of the left template seat and the right template seat are respectively connected to the die underframe through sliding grooves; the left end and the right end of the lower template are respectively connected with the bottom end of the left template seat and the bottom end of the right template seat.

The mould demoulding mode of the two I-shaped piles is lateral demoulding, and the side templates of the mould demoulding mode need to be overturned laterally or move laterally, so that corresponding abdication spaces are needed on the left side and the right side of the mould, the whole width dimension of the mould is larger, the number of moulds which can be placed in the space with the same width is small, and the utilization rate of a factory building is greatly reduced. In addition, the existing mould can only produce I-shaped piles with one width size model, which indirectly leads to the increase of the mould cost.
