An airbag inflator device

Abstract

This invention provides an airbag inflator device, characterized in that it comprises: a main body having a high-pressure air inlet, a cooling water inlet, a cooling water outlet, a cylinder extension air inlet, a cylinder return air inlet, an inner cavity of the main body, and a water-cooled heat insulation plate; it also has a hot pressing mechanism, a cooling mechanism, and a demolding mechanism. On one hand, the high-pressure air inlet is connected to the upper air chamber. When high-pressure gas is input into the upper air chamber through the high-pressure air inlet, the deformation of the fluororubber sheet in the gap space drives the pressure rod to apply pressure to the inflator. The deformation of the fluororubber sheet is a flexible change process, which can reduce the impact on the product; moreover, it is in full contact with the pressure rod, the pressure is uniform, and the pressure control accuracy is high. The water-cooled heat insulation plate is located between the fluororubber sheet (and sealing rings and other sealing components) and the heating block. When the heat generated by the heating block is transferred to the fluororubber sheet, it can be quickly blocked and dissipated by the water-cooled heat insulation plate.
