The airbag lock molding device belongs to the technical field of brick making machine equipment, including supporting seats and leverage in the central part with the support seat connection. There are pressure blocks at the bottom of the lever at the bottom of the leverage. There is an airbag with a lower connection board, which is fixed at the bottom of the leverage at the bottom of the leverage. The working principle is to fill the inert gas or oil and gas mixture in the closed pressure cylinder, so that the pressure in the cavity is higher than the atmospheric pressure than the atmospheric pressure. Several times or dozens of times, the cross -sectional area of the piston rod is smaller than the cross -sectional area of the piston to achieve the pressure difference between the piston rod.
The pneumatic molding device of the present invention has a simple structure, convenient and practical, safe and reliable, low production costs and maintenance. By controlling the airbags to load or remove the lock effect by controlling the airbags, it is convenient for the disassembly of the mold. At the same time The role of a certain buffer and shock absorption has improved the stability of the mold under vibration.
