Description
Technical Field
The utility model belongs to the technical field of support protection film production facility and specifically relates to a mould on blanking for blanking support protection film is related to.
Background
It is known that miniature cameras are an important component of mobile phones and, because of their high integration and optical-grade production and operational requirements, there is an important die-cut component-support protection film during their production testing and transportation. The main function of the support protective film is to protect the miniature camera from being impacted and placed dust to enter in the testing and transportation process, and in addition, the support protective film also needs high light transmittance so as to facilitate the testing. Fig. 1 shows a conventional stent protective film, which includes a high-transmittance auxiliary material 91, an annular thick foam 92 adhered to the lower side of the high-transmittance auxiliary material 91, and a base adhesive auxiliary material 93 adhered to the lower side of the thick foam 92.
As shown in fig. 2, a conventional cutting die for a protective film of a bracket comprises an upper die plate 1 and a lower cutting die 103, wherein a blanking blind hole 101 is formed in the lower side of the upper die plate 1, a foam block 102 is filled in the blanking blind hole 101, and an outer convex cutting edge 4 is integrally formed along the lower edge of the blanking blind hole 101 in the lower side of the upper die plate 1.
When the die is used for cutting the material belt to form the support protective film, the material belt penetrates through the space between the upper die plate 1 and the lower cutting die 103, the upper die plate 1 is pressed on the lower cutting die 103 by virtue of a punching machine, so that the material belt is cut by the cutting edge 4 to form the support protective film, and meanwhile, the foam block 102 is pressed to blank the blind hole 101 to be sunken; when the upper die plate 1 leaves the lower cutting die 103, the foam block 102 is deformed again to eject the support protective film from the punched blind hole 101. Because thick bubble cotton 92 can be stressed and its self has the ability of resumeing deformation again at the in-process of blanking, so it can expand tightly in blanking blind hole 101 after the support protection film cuts the shaping, and the border of primer auxiliary material 93 has the glue in addition, leads to the support protection film to rely on bubble cotton piece 102 with it ejecting from the support protection film, and its self is difficult for following blanking blind hole 101 and automatic the deviating from. However, the foam block 102 has a limited ability to recover deformation, and the foam block 102 cannot eject the punched stent protection film out of the punched blind hole 101 after being used for a period of time. And because the foam block 102 is soft, the high-permeability auxiliary material 91 on the protective film of the bracket can be easily crushed in the blanking and forming process of the protective film of the bracket.
