[0002] For the shell with curved surface structure, when designing the mold, it is necessary to set the male mold to the corresponding curved surface structure, so that the required curved surface shell can be made through the injection molding process. To form the corresponding texture on the curved surface shell, usually Process the corresponding texture structure on the curved surface of the male mold core, so that the corresponding texture can be formed on the curved surface of the curved shell after injection molding, but this method is difficult to process and requires high equipment (requires multi-axis linkage). The texture structure processed on the curved surface is prone to interference defects, which affects the texture quality of the shell after molding

Embodiment 1

[0032] figure 1 It is a schematic diagram of an embodiment of the mold core of the present invention, figure 2 is a schematic diagram of one embodiment of an insert, image 3 It is a schematic diagram of an embodiment of the first core, please also refer to Figures 1 to 3 , the mold of this embodiment includes a mold core 10, the mold core 10 is provided with a cavity 20 for forming a shell with a curved surface, the first molding surface 21 of the cavity 20 is a curved surface structure, and is used for forming the shell on the shell. surface. Moreover, an insert 30 is detachably arranged on the first molding surface 21. The insert 30 is flexible and can be attached on the first molding surface 21 according to the shape of the curved surface structure of the first molding surface 21. The insert 30 faces A textured structure 31 is provided on one side surface of the cavity 20, so that textures can be formed on the curved surface of the casing after molding.

Abstract

The invention relates to the technical field of electronic devices, and discloses a mold, a shell and a manufacturing method of a texture on a curve shell. The mold comprises a mold core, the mold core is provided with a cavity, a first forming face of the cavity is of a curve structure, and is used for forming a curve face on the shell, the first forming face is detachably provided with an embedded part, the embedded part is flexible and can be attached to the first forming face according to the shape of the curve structure of the first forming face, a texture structure is arranged on the surface of the side, facing the cavity, of the embedded part, the embedded part is attached to the curve forming face, mold assembly injection molding is carried out, the texture on the curve shell is formed after demolding of the position corresponding to the texture structure, through the mold, the texture on the curve shell and the shell body are subjected into injection molding into a whole, andthe curve shell with the texture can be formed. The procedure of machining the texture structure on the curve forming face of the mold core can be omitted, the texture machining difficulty on the curve shell can be reduced, and the texture forming quality is ensured.
