Description

Technical Field

[0001] The utility model relates to the technical field of aerospace material production, in particular to a forming die for an aerospace bracket. Background Art

[0002] Aerospace materials are a general term for various materials used to manufacture aircraft, aircraft engines, and airborne equipment. Brackets are also one of the manufactured accessories. The molding of brackets usually requires a molding mold, and is obtained by injection molding, blow molding, die casting, and other methods.

[0003] When optimizing the existing forming molds for aerospace brackets, most of them are reflected in correcting the docking between the movable mold frame and the fixed mold frame. For example, the Chinese utility model patent with application number CN201810082131.7 discloses "A forming mold for an aerospace bracket". In this device, guide rods are installed at the four corners of the top of the fixed mold frame, and pillars are installed on the front and rear ends of the fixed mold frame. The hydraulic press controls the hydraulic pump to drive the push rod to move, and the guide rod drives the movable mold frame to move. An open conduit is provided at the bottom end of the guide hole to facilitate the entry of the guide rod, and the guide rod is introduced into the depth of the guide hole through the open conduit, thereby effectively correcting the deviation when the movable mold frame and the fixed mold frame are docked, making the docking operation of the movable mold frame and the fixed mold frame convenient and quick, saving time and effort, and effectively improving work efficiency.

[0004] Although the above-mentioned aerospace bracket molding mold has certain advantages in the convenient and quick docking operation between the movable mold frame and the fixed mold frame, it still has certain disadvantages: after the injection liquid is injected into the mold, it will generate expansion force on the upper mold plate and the lower mold plate due to the factor of thermal expansion. The expansion force is large, causing the upper mold plate and the lower mold plate to pull apart, affecting the molding effect of the bracket. Utility Model Content
