[0022] During specific implementation, in order to facilitate the operation of workers and save time and energy, after the concrete is injected into the template frame 3, it is left to stand for a period of time until the concrete is formed. When demoulding, the automatic demoulding mechanism 2 is used, and the bidirectional driving motor 21 is started to drive the active gear disc 22 to engage with the first driven gear disc 23 and the second driven gear disc 24 to drive them to rotate. When the first driven gear disc 23 and the second driven gear disc 24 rotate, the forward threaded rod 231 and the reverse threaded rod 241 in the middle thereof rotate accordingly, and respectively interact with the forward thread groove 251 and the reverse thread groove 252 to lift the template frame 3 to the top through the connecting frame 25, and the demoulding of the concrete template can be completed at this time.
