Vibration demolding device

The utility model discloses a vibration demoulding device which comprises a device base, a device top plate and a movable mounting plate, a second threaded rod is arranged between fixing supports, and a movable limiting plate is arranged on the outer surface of the second threaded rod. The vibration demolding device is provided with the spring shock absorbers, the spring shock absorbers increase the amplitude of exciting force, meanwhile, the damage of the exciting force to weld joints between the base and the base foundation is buffered, the service life of the vibration device is prolonged, the exciting force of the vibration machine is transmitted to the steel mold, and the sleeper is separated from the steel mold and falls onto a conveying roller way through the action of the exciting force and the dead weight of the sleeper. Therefore, convenient and quick demolding is realized; a movable mounting plate in a mounting groove in a top plate of the device can move along a limiting sliding groove in the moun
