no. 1 approach

[0023] The method for manufacturing a frame structure for portable terminal equipment according to the first embodiment of the present invention includes: a frame manufacturing step, a metal frame forming step, and a plastic frame forming step.

[0024] In the frame manufacturing step, a metal material is processed to manufacture the metal frame 100 . Further, in the frame manufacturing step, the metal frame 100 is manufactured by performing molding processing such as forging and extrusion and machining such as CNC processing on the metal material. Such as figure 1 and figure 2 As shown, in the frame manufacturing step, the first coupling protrusion 110 and the first coupling groove 120 are respectively formed on the inner side of the metal frame 100 forming the metal bracket 200 . The first coupling protrusion 110 is inserted into the metal bracket 200 during the forming step of the metal bracket, and the first coupling groove 120 is immersed in molten metal during the mol...

no. 2 approach

[0038] A method for manufacturing a frame structure for portable terminal equipment according to a second embodiment of the present invention includes: a frame manufacturing step, a metal frame forming step, and a plastic frame forming step.

[0039] In the frame manufacturing step, on the inner side of the metal frame 100 where the metal bracket 200 is formed, the first coupling protrusion 110 is formed. The first coupling protrusion 110 is composed of a coupling part 110a for improving the coupling force between the metal frame 100 and the metal bracket 200 and a guide part 110b for guiding the coupling position of the metal frame 100 inside the first mold. That is to say, the coupling part 110a protrudes from the inner side of the metal frame 100 and is inserted into the metal bracket 200; the guide part 110b protrudes from the lower part of the coupling part 110a to guide the position where the metal frame 100 is coupled to the first mold.

no. 3 approach

[0043] A method for manufacturing a frame structure for portable terminal equipment according to a third embodiment of the present invention includes: a frame manufacturing step, a metal frame forming step, and a plastic frame forming step.

[0044] In the frame manufacturing step, on the inner side of the metal frame 100 where the metal bracket 200 is formed, the first coupling protrusion 110 or the first coupling groove 120 is formed. That is, on the inner side of the metal frame 100, any one of the first combining protrusion 110 and the first combining groove 120 may be formed.

[0045] Further, in addition to the usual protruding formation of the first coupling protrusion 110, such as Figure 4 As shown, various shapes such as T-shape and ㄴ-shape can be formed. another example Figure 5 As shown, a through hole 111 may be formed on the first coupling protrusion 110 for immersion in molten metal. That is to say, in the forming step of the metal bracket, molten metal is i...

Abstract

The invention relates to a framework structure manufacture method of a portable terminal apparatus, by which a metal framework structure can be produced; the mechanical processing part can be separated from the casting manufacturing part; the mechanical processing is reduced in maximum degree; and the productivity and quality can be raised. The framework structure manufacture method of a portable terminal apparatus is characterized in that the method comprises the steps of injecting molten metal in the step of manufacturing metal framework and after inserting the metal framework into a first die; and forming a metal support as a whole as the inner side of the metal framework.

Description

technical field [0001] The invention relates to a method for manufacturing a frame structure for portable terminal equipment. The metal frame structure can be manufactured, the machining part can be separated from the casting part, the machining can be minimized, and the productivity and quality can be improved. Background technique [0002] Portable terminal devices such as smart phones, with the requirements for large screens and thin screens, in order to enhance their structural strength, more and more internal and external metal materials are used. In particular, external parts, as the parts that consumers are in direct contact with visually and tactilely, have higher and higher requirements for their aesthetics, quality and differentiation. Currently, various materials and manufacturing methods are used to express their appearance and texture. According to different materials and manufacturing methods, the manufacturing cost has increased, and there are also problems s...
