Since the raw material is a flat material and the shape of the final product is a three-dimensional shape, the material will undergo a series of changes such as extension, flow, elastic deformation, and plastic deformation during the forming process. In order to prevent the material from being unstable and wrinkling during the stretching process, At the same time, the shape of the product meets the tolerance requirements. The mold must first be supported by the lower ejector cylinder to complete the forming of the parting surface, and then the mold blank holder and the ejector have continuous and stable pressure at the same time.
