2. Description of the Related Art Generally, a terminal such as a personal computer, a notebook computer, a cellular phone, or the like has a variety of functions, and a multimedia device having a complex function of shooting a picture or a moving picture, playing music or a moving picture file, (Multimedia Player).

The mobile terminal can be divided into a mobile terminal and a stationary terminal according to whether the mobile terminal can be moved or not. The mobile terminal can be divided into a handheld terminal and a stationary terminal Vehicle Mount Terminal).

Further, in order to support and increase the function of the mobile terminal, it is considered to improve a structural part or software part of the terminal, and since a thin case is fastened and assembled, the case of the mobile terminal is made thinner There is a need for an efficient method to be implemented.

The case of the mobile communication terminal is mainly manufactured by resin injection molding. A plurality of insert nuts for fastening and fixing other parts to the case of the mobile communication terminal, Respectively.

The injection mold apparatus of the mobile communication terminal case in which the fastening nut is insert-molded according to the prior art includes a fastening nut insertion pin which is inserted into the fastening nut N1 for fastening and fixing the components and prevents the fastening nut from flowing, And a plurality of gates serving as passages for injecting the molding resin into the cavities are formed in the cavities by molding the cavities in the resin molding space by the combination of the fixed mold and the mold And a movable mold.

The operation of the injection mold apparatus of the case of the mobile communication terminal having the above-described conventional structure in which the coupling nut is insert-molded according to the related art will be described. In the state where the coupling nut is inserted into the cavity by the coupling nut insert device, The case of the mobile communication terminal in which the fastening nut is integrally formed is completed.

Recently, resin molded products tend to prefer terminals or cases using an aluminum material to make use of metal-specific color and properties. Therefore, it is necessary to perform molding using aluminum metal, but unlike ordinary resin injection, there is a problem that it is difficult to form an internal shape.

1 is a perspective view showing a case manufactured by a method of forming an aluminum case using a press according to the prior art of the present invention.

Referring to FIG. 1, a case manufacturing method according to the related art includes a die casting process for molding a liquid metal by injection at a high pressure, a bending process for molding the panel member by a press die, Process.

The terminal case formed by any one of the manufacturing methods described above is bent in one direction to form an inner space so that various parts can be installed. In the inner wall forming the inner space, parts are installed, And a protrusion constituting a rib for reinforcement are formed.

A method of manufacturing a terminal case using a bending process in the above-described molding method includes a step of molding a case of a primary shape by press processing a thin sheet, an insert injection or bonding process of a case of a primary shape, . ≪ / RTI >

BACKGROUND ART [0002] The background art of the present invention is disclosed in Korean Patent Laid-Open Publication No. 10-2013-0066854 (published on Jun. 21, 2013, entitled "Case Manufacturing Method and Mobile Terminal).

When aluminum is used as a material, the die casting is formed by injecting a liquid metal at a high pressure. In the die casting case, an inner boss or a rib is well formed, but an anodizing treatment is not performed.

In the case of bending, the material is bent and formed, and the hole is punched to form a basic shape. In this case, there is no inner shape of the case, so that it is difficult to assemble the parts, additional molding and machining such as injection and the like are required and the outer working is required.

In the case of molding by press, in the case of a conventional bending mold, the upper mold with the engraved shape is lowered while the material is inserted, and bending is performed. That is, the bending is performed while bending the material along the grooves of the upper mold and the lower mold.

In the case of forging, the boss and the ribs on the inner side of the case are irregularly formed, the dimensional accuracy is poor, and the flatness is not produced. This also requires external machining, which complicates the process.

In the case of machining, it takes 40 minutes to 1 hour per piece to realize a precise case product of a mobile terminal, resulting in a very low productivity, which causes a huge cost increase. The raw material consumption is also unreasonable from the point of view that the byproduct to be disposed of irrespective of the product has increased from 80% to 95%, which is not only costly but also waste of raw materials.

Due to these problems, there was a need for a method that can realize the precision boss or ribs inside by pressing the aluminum material.

Among the case manufacturing methods according to the prior art, there is a problem in that bosses and ribs are well formed in the inner space formed by die casting, but the anodizing treatment is not performed and the appearance is not beautiful.

Since the base is formed by bending a material and punching holes to form a basic shape, the protruding portion constituting the rib or the boss is not provided on the inner wall forming the inner space of the case, And there is a problem that an additional process such as an injection process for molding the protrusion is required.

In addition, the case manufacturing method by the forging process according to the prior art has the problem that the formability of the boss or the protrusion forming the ribs inside the case is irregular, the dimensional accuracy is low, and the flatness is also poor .

Therefore, there is a need for improvement.
