The fixing frame is arranged in the inner die, the vibrator is fixedly arranged on the fixing frame, and the vibrator has the function of providing a vibration effect for the inner die, so that concrete is poured while being vibrated and compacted, and the concrete is better formed.

Preferably, an exhaust gap is reserved between the inner die and the forming cavity, an exhaust hole communicated with the exhaust gap is formed in the bottom of the inner die, and an exhaust pipe is arranged at the top of the inner die. The exhaust gap, the exhaust hole and the exhaust pipe form an exhaust device, so that the inner die can be smoothly lifted out during demolding, the difficulty during demolding is reduced, and the damage to a concrete inspection well during demolding is reduced.

Preferably, the locking structure comprises a plurality of locking spanners connected between the outer mold and the inspection well base. The locking spanner has the function of fixing the outer mold on the inspection well base, ensuring the stability of the outer mold in the molding process of the concrete inspection well, and releasing the locking spanner after molding so as to facilitate the hanging out of the outer mold.

Therefore, the concrete inspection well forming device convenient for demoulding has the following advantages: the concrete inspection well can be formed quickly, the inner die and the outer die can be removed quickly, the turnover demoulding is not needed, and the damage to the formed concrete inspection well is effectively avoided.
