Description

Mobile phone shell forming device Technical Field The utility model relates to the technical field of electronic equipment accessory forming devices, in particular to a mobile phone shell forming device. Background The mobile phone cover plays a role in protecting the mobile phone, the designed and produced outer cover is diversified along with the increase of brands and functions of the mobile phone, the mobile phone cover is divided into leather, silica gel, cloth, hard plastic, soft plastic, wool, silk and other products according to the texture, and the mobile phone cover is divided into a straight plate, a flip and a folding difference according to the model. Taking a folding mobile phone case as an example, in the production process of a mobile phone shell, a layer of leather is generally adhered to the outer surface of a hard PC shell, and redundant leather is removed by cutting after molding, so that the core links of the product size precision and the edge flatness are determined; in the production process of the folding mobile phone cover, the mobile phone cover needs to be punched, the mobile phone cover to be processed needs to be sleeved on the profiling block, and the mobile phone cover sleeved on the profiling block is punched through a punching device; The current pre-compaction device often sets up on die-cut board of die-cut device, along with die-cut board removes, consequently can only carry out simple pre-compaction to the cell-phone shell that the cover was established on the profile modeling piece before die-cut, because the placing of cell-phone shell is mostly placed through the manipulator, places the deviation appears relatively easily, is difficult for once only placing in place, if just precompressing it before die-cut, easily leads to die-cut hole site to appear the deviation, reduces the product percent of pass.
