Description
Technical Field
The utility model relates to a technical field of mould structure, especially a collection tears and shaping in forming die of an organic whole.
Background
The finished cambered part structure is shown in fig. 1, and comprises a bottom plate 24 and an arc-shaped plate 25 integrally formed with the bottom plate 24, wherein a release film 26 is arranged on the bottom surface of the finished part, and the bonding surface of the release film 26 is bonded on the bottom surfaces of the bottom plate 24 and the arc-shaped plate 25. The finished product of the arc-shaped part is processed from a blank, the structure of the blank is shown in figure 2, the blank comprises a thin plate 27 and a release film 26 adhered to the bottom surface of the thin plate 27, the left end part of the release film 26 extends to the outside of the thin plate 27, the method for processing the finished product of the arc-shaped part by using the blank is to cut the release film 26 along the left end surface of the thin plate by adopting a cutter so as to cut off the left extending end part of the release film 26, at the moment, the release film 26 completely covers the thin plate 27, finally, the thin plate 27 is sent into a stamping die, an arc-shaped plate 25 is formed at the left end part of the thin plate 27 by the die, and the finished product of the arc-shaped part can be processed finally. However, although the finished product part with the cambered surface can be processed by the processing method, the finished product part with the cambered surface can be formed only by dividing the processing method into two steps, which undoubtedly increases the forming time of the single part, further reduces the production efficiency of the finished product part with the cambered surface, and is difficult to meet the market demand. In addition, the cutter can not cut off the left end portion of the release film at one time, so that the tearing efficiency of the release film is reduced. Therefore, a forming die for improving the production efficiency of finished parts with cambered surfaces is needed.
