Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.

The utility model is further described with reference to the following detailed description and accompanying drawings.

Referring to fig. 1 to 6, a die for area film plating comprises a first die box 1 and a second die box 2 which are made of stainless steel in a set, a first shielding strip 11 and a second shielding strip 12 are left in a hollow manner on a bottom plate of the first die box 1, the first shielding strip 11 is arranged in the middle of the first die box 1, the second shielding strip 12 is symmetrically and vertically connected to the middle of the first shielding strip 11, so that a film plating product 3 is shielded by the first shielding strip 11 and divided into two parts, a first film layer is plated through a large film plating hole surrounded by the second shielding strip 12, the first shielding strip 11 and a bottom plate side wall of the first die box 1, a film plating hole 21 corresponding to the second shielding strip 12 in an up-and-down overlapping manner is arranged in the middle of the bottom plate of the second die box 2, a second film layer is plated through the film plating hole 2, and the periphery of the bottom of the hollow portion of the bottom plate of the first die box 1 and the periphery of the bottom of the film plating hole 21 are chamfered at an angle of 45 degrees, namely, the side walls of the bottom plates of the barrier strip II 12, the barrier strip I11 and the die box I1 are surrounded to form a coating film large hole, the periphery of the bottom of the coating film large hole and the periphery of the bottom of the coating film hole 21 are respectively subjected to 45-degree chamfering treatment, so that the edge effect of a coating film layer is better, the coating film edge is not rough, the error is small, and the edge precision of the coating film layer can be accurately controlled. When the die box is used, the film coating product 3 is firstly placed into the die box 1, when a film coating layer is evaporated from the bottom of the die box 1 upwards, a film layer of a zoneB area can be coated, the zoneA area and a middle blank area are shielded by the shielding strips 11 and the shielding strips 12, so that the film coating layer cannot be coated, the film coating product 3 is taken out from the die box 1 and placed into the die box 2 for coating, only the zoneA area is coated at the moment, the coated film coating product after coating is obtained is shown in a figure 6, and finally the film coating film 4 is obtained by cutting along a dotted line, so that the transition area can be controlled below 0.5mm, in order to further reduce the transition area, the bottom of the bottom plate of the die box 2 is provided with the thinning groove 22, the thinning groove 22 surrounds the film coating hole 21, the thickness around the film coating hole 21 is further reduced through the thinning groove 22, and the edge of the film coating is further accurately reduced, this makes it possible to control the transition region to be less than 0.3mm, making the transition region narrower.

For the bottom plate of laminating diaphragm box 1 and diaphragm box two 2 that makes the diaphragm can be better to it is more accurate to make the coating film edge, the plane degree of the bottom plate of diaphragm box 1 and diaphragm box two 2 is according to the medium level management and control.

According to the utility model, the first die box and the second die box are adopted to separate the shielding coating, so that different coating layers can be conveniently coated on two areas on the same surface of the lens, the transition area can be controlled below 0.3mm, and meanwhile, the good smoothness of the product can be ensured, and the product quality is improved.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any minor modifications, equivalent changes and modifications made to the above embodiment according to the technical spirit of the present invention are within the technical scope of the present invention.
