Reshaping die

Abstract

The invention belongs to the technical field of dies, and particularly relates to a reshaping die. The reshaping die is used for reshaping two opposite side walls of parts with formed depths. The reshaping die comprises an upper die plate, a lower die plate and carrying inserts, wherein the upper die plate and the lower die plate are oppositely arranged up and down. An upper die insert is arrangedat the side, facing the lower die plate, of the upper die plate. A lower die insert is arranged at the side, facing the upper die plate, of the lower die plate. The carrying inserts are arranged between the upper die insert and the lower die insert and are further connected with the lower die plate through springs. The contact surfaces of the carrying inserts and the upper die insert serve as first molded surfaces. The contact surfaces of the carrying inserts and the lower die insert serve as second molded surfaces. When parts are placed on the carrying inserts, the two opposite side walls ofthe parts are arranged up and down. The first molded surfaces are tilted downwards, and the second molded surfaces are tilted upwards. By the aid of the reshaping die, reshaping can be conducted in the way that the included angles of the two opposite and parallel side walls of the parts with the formed depths and a top plate are smaller than 90 degrees.

Description

Technical field [0001] The invention belongs to the technical field of molds, in particular to a plastic mold. Background technique [0002] Many stamping parts in automobile body-in-white have complex shapes and deep forming depths. Due to the forming characteristics of the material itself, springback will occur after forming, and it needs to be reshaped to meet product requirements, such as figure 1 Shown is the left mounting bracket for the subframe of a certain vehicle model. Its parts have a depth of molding and a complex shape like a "several" shape. It has two relatively parallel side walls and is arranged on the same side of the two side walls and fixedly connected to both sides. The top plate of the wall, the left mounting bracket of the sub-frame has a deep molding depth. According to product performance requirements, both the first side wall 01 and the second side wall 02 of the part need to be completely perpendicular to the top plate 03 of the part at an angle of 90°....

AI Technical Summary

Problems solved by technology

[0004] In prior art shaping molds for the left mounting bracket of the sub-frame, when the upper mold base moves downward toward the lower mold base to shape the left mounting bracket of the sub-frame, since the opening of the left mounting bracket of the sub-frame is sleeved downward On the shaping insert, as the upper mold base goes down, it can only be realized that the included angles between the first side wall 01 and the second side wall 02 of the left mounting bracket of the sub-frame and the top plate 03 of the part are greater than The shaping equal to 90° cannot realize the shaping that the included angles between the first side wall 01 and the second side wall 02 and the top plate 03 of the part are less than or equal to 90°

If springback occurs after shaping, the product demand cannot be met, and a process must be added to perform side shaping on the first side wall 01 and the second side wall 02 through the wedge, which will lead to waste of cost
