Air bag demoulding and pulling device for forming cap-shaped stiffened wall plate and demoulding method

The invention discloses a cap type stiffened wallboard forming air bag demolding and pulling device and a demolding method. The cap type stiffened wallboard forming air bag demolding and pulling device comprises a base platform, a pulling and pulling executing mechanism arranged on the base platform and a driving mechanism for providing power for the pulling and pulling executing mechanism. A baffle is arranged at the front end of the base platform, and an air bag clamp is arranged at the front end of the pulling execution mechanism. A cured cap-shaped stiffened wallboard workpiece is placed at the front end of a baffle, an air bag exposed out of a cap-shaped wallboard cavity is clamped on an air bag clamp, and a pulling execution mechanism is driven by a driving mechanism to pull out the air bag at a constant speed, so that the problem that the air bag is broken due to uneven stress is effectively solved; and favorable conditions are provided for realizing mechanical and standardized production of cap-shaped
