AI Technical Summary
In existing technologies, the demolding efficiency of concrete-lined pipe segments is low, and the residual concrete on the inner wall of the mold needs to be cleaned manually, which affects work efficiency.
The system employs a striking mechanism and a lifting mechanism. A motor drives a double-headed threaded rod to engage a slider and gears. The striking ball strikes the side wall of the mold to remove residual concrete, while the lifting plate ejects the pipe segments, thus achieving automated demolding.
It improves demolding efficiency, reduces manual cleaning work, and realizes a fast and automated segment demolding process.
