Abstract

The application provides an auxiliary forming frame for an ultra-thin frame, which comprises a frame body and a support block. The frame body comprises a connecting support arm and two side support arms. The two side support arms are arranged, and the two ends of the connecting support arm are connected with one end of the corresponding side support arm. The outer contour of the frame body is matched with the contour of the ultra-thin support piece. The frame body is used for abutting against the ejector pin of the ejection mechanism when the ultra-thin support piece is demolded. A plurality of support blocks are arranged at intervals along the frame body. The two ends of each support block are connected with the frame body and the ultra-thin support piece. The frame body, the support block and the ultra-thin support piece are integrally formed. The auxiliary forming frame for the ultra-thin frame uniformly supports the ultra-thin support piece through the interval arrangement of the support blocks, avoids the deformation of the ultra-thin support piece, and improves the quality of the ultra-thin support piece. In the demolding process, the ejector pin acts on the frame body of the auxiliary forming frame for the ultra-thin frame, avoids leaving the ejection marks on the surface of the ultra-thin support piece, and improves the surface quality of the ultra-thin support piece.
