Description

Technical Field

[0001] The utility model relates to the technical field of inner cavity forming, in particular to an inner cavity forming device for a superplastic deformation die. Background Art

[0002] At present, superplastic deformation die is a special die used in superplastic forming process. Superplastic forming is a process method that uses superplastic metal as mold cavity blank. Under the superplastic state, the process punch is pressed into the interior of the blank to realize mold cavity forming processing. This method utilizes the superplasticity of metal under specific conditions for forging and forming. Superplastic forming can realize the manufacture of complex shapes in a one-time forming process, which can not only reduce subsequent processing steps, but also improve the quality and performance of parts.

[0003] The prior art has an authorization announcement number of CN217801249U, which discloses a glass mold inner cavity processing fixing mechanism, including a base, an electric push rod, a lifting plate, a first vertical plate, a second vertical plate and a stage. Two electric push rods are fixedly installed on the base, and their output shafts are commonly connected to a lifting plate. The first vertical plate and the second vertical plate are installed on the top of the lifting plate. The two are connected to each other through a connecting shaft in a mounting hole, and the stage is allowed to be firmly clamped between the two. The height position of the stage (and the glass mold clamped thereon) can be conveniently adjusted by lifting and lowering the electric push rod, and the setting of the connecting shaft allows the stage (and the mold) to be adjusted to a certain tilt angle to meet different processing requirements. In addition, the mounting hole design on the first vertical plate and the second vertical plate enables the patent to firmly clamp glass molds of various shapes, greatly enhancing its practicality and scope of application.
