Hydraulic forming device of molybdenum grid for iron thruster

The invention relates to a hydraulic forming device of a molybdenum grid for an iron thruster and belongs to the technical field of drawing molding manufacturing of metal parts. The device mainly comprises an upper forming mold, a lower forming mold, a liquid medium thermal control box, a connector, a hydraulic unit, a hydraulic pipe, an exhaust pipe, a seal ring and a pressurizing lining plate. The lower forming mold is fixedly mounted in the bottom of the liquid medium thermal control box, and the molybdenum grid for compression moulding and the pressurizing lining plate are successively arranged on an annular positioning table of the lower forming mold; the seal ring is arranged between the pressurizing lining plate and the upper forming mold, the exhaust pipe is connected to an exhaust port of the upper mold, and the hydraulic unit is connected to a liquid inlet of the upper forming mold through the hydraulic pipe; one end of the connector is fixedly connected to the upper forming mold while the other end is fixedly connected to mold closing pressure equipment. The device provided by the invention can guarantee the uniformity of a pressing force at the edge of the molybdenum grid so as to avoid wrinkling of the molybdenum grid in the forming process due to local suffocation.
