Production method of divider component for liquid enclosure type vibration-proof device and divider component for its liquid enclosure type vibration-proof device

摘要

While guaranteeing the connecting strength of the orifice component and the elastic divider membrane, the divider component for the liquid enclosure type vibration-proof device which can achieve the substantial reduction of the production cost the adhesive as unnecessary, and thatProduction method of the divider component for the liquid enclosure type vibration-proof device is offered. At least, it inserts that elastic divider membrane, inside the die for resin ejection the elastic divider membrane which possesses the perforation hole of 1 it forms with vulcanization forming step, in order for the region which includes the perforation hole to be located inside the ejection space, in insertion process. And, in resin forming step, beginning shooting the resin material inside the ejection space of the die for resin ejection, the orifice component elastic divider membrane it forms as one unit. Because of this, it is possible to assure the substantial reduction of production cost, the adhesive as unnecessary. Furthermore, filling up the resin material of the orifice component in the penetration borehole of the elastic divider membrane, because it forms the coming out prevention expedient of the elastic divider membrane for the orifice component in the filling up section, it is possible to guarantee the connecting strength of both components securely.
