Description

TECHNICAL FIELD

[0001] The utility model relates to mobile phone battery cover appearance texture technical field, concretely relates to a 3D stereoscopic magnetic texture mould. BACKGROUND

[0002] The present mobile phone industry battery cover appearance texture has two kinds of implementation schemes:

[0003] 1. High-end machines adopt photoetching texture technology.

[0004] 2. Low-end machines adopt spraying color matching texture.

[0005] The shortcomings of the above two schemes are:

[0006] Photoetching texture: the photoetching mould is expensive, a set of mould is several hundreds of thousands or even a million, and the post-process flow is more and complex, and the yield is not particularly high, so that the whole process cost is relatively expensive. At present, only top flagship machines adopt this process texture.

This technology has no innovation ability and does not meet the continuous development direction of future appearance texture. INVENTION CONTENT

[0008] The utility model aims at overcoming the defects of the prior art, and provides a 3D stereoscopic magnetic texture mould, solves the defects of high cost of photoetching mould, low post-process yield and high cost, and fills the problems of too ordinary spraying texture effect and poor product competitiveness.

[0009] The technical scheme of the utility model is as follows:

[0010] A 3D stereoscopic magnetic texture mould, comprising an upper mould plate and a lower mould plate, the lower surface of the upper mould plate is embedded with a plurality of first rubber magnets arranged side by side, the upper surface of the lower mould plate is embedded with a plurality of second rubber magnets arranged side by side, the first rubber magnets and the second rubber magnets form a magnetic field based on the positive and negative repulsion principle, a diaphragm is placed on the upper mould plate, a magnetic ink is coated on the surface, a 3D stereoscopic magnetic texture is formed under the action of the magnetic field of the first rubber magnets and the second rubber magnets, and the surface of the diaphragm has a 3D stereoscopic dynamic effect after texture forming.

[0011] Further, the plurality of first rubber magnets can be cut into different shapes according to customer requirements.
