Abstract

The utility model relates to a forming mold for an aerospace bracket, comprising an upper cover plate, a lower cover plate, a connecting rod, a sleeve connecting rod, an upper template, a lower template, a liquid injection port and a supporting leg. A movable body is provided to drive a hydraulic cylinder so that the lifting plate generates an upward thrust on the bottom, and the side ends of the hinged connecting rods change their positions, thereby driving the hinged connecting frames to generate swinging activities and gradually tend to be vertically arranged. At the same time, the changing frame is also driven by the lifting plate to move. Therefore, the swing folding block can assist in driving the displacement of the buckling block while also driving it to swing, so that the buckling block changes from a vertical direction to a horizontal arrangement, and its front end is buckled on the lateral upper end surface of the upper cover plate, thereby the two movable bodies provided generate a downward pressing effect on both sides of the upper cover plate at the same time, so as to prevent the injection molding liquid from pulling the distance between the upper template and the lower template apart due to thermal expansion, so that the upper cover plate will automatically move upward, thereby affecting the forming effect of the bracket.
