Description

[0001] The present invention relates to a jig device for removing a burr of a mobile phone,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a jig device for removing a cellular phone case burr, and more particularly, to a jig device for removing a cellular phone case burr at the same time to remove burrs formed inside and outside of the cellular phone case.

BACKGROUND ART [0002] Generally, a cellular phone which has become a necessity of modern people includes an electronic case and an inner case for supporting and assembling the respective parts, and the inner case is manufactured by molding after injection molding or the like.

Injection molding as described above is performed by injecting a molten solution heated by a molding material into a cavity of a mold through a gate, filling and curing the material by cooling, separating the mold from the mold, Burrs are inevitably generated inside and outside the injection-molded article.

Such inner and outer burrs must be removed for the purpose of post-processing in small electronic products such as mobile phones requiring precision. In the past, they have been manually removed or the inner and outer burrs have been separately processed, In addition, not only the productivity is decreased but also the labor cost is increased due to overproduction of the workforce, resulting in a rise in the product unit price in the end.

In addition, there is a problem that a separate process is further added or a workforce is further required to clean and polish the surface of the mobile phone case.

The jig device for removing the cellular phone case burr of the present invention will be described in more detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a jig device for removing a cellular phone case burr according to the present invention, FIG. 2 is an illustration of a strap-like state in which an outer cutter is passed through a support of the present invention, FIG. 5 is a perspective view showing a state of a combined strap according to the present invention, and FIG. 6 is a perspective view showing a state in which the cutting insert of the present invention Fig. 8 is an illustration of a cellular phone case molding state through a jig device.

As shown in the drawings, the jig device for removing the cellular phone case burr of the present invention comprises a lower frame 10, an outer cutting member 20, an inner cutting member 30, and an upper frame 40.

The lower frame 10 used in the present invention is provided with a plurality of supporting members 14 having a seating groove 12 so that the cellular phone case 5 formed in the upper part is seated on the upper part as shown in Figs. The support 14 protrudes from the lower frame 10 and a plurality of spacers 17 protrude from the upper surface of the lower frame 10 to prevent friction with the outer cutter 20.

The outer cutting member 20 provided at the upper portion of the lower frame 10 penetrates through the outer frame of each support member 14 as shown in FIG. 2 to penetrate the outer shape burr 3 formed on the outer shape of the mobile phone case 5 A cutting hole 22 is formed. The outer cutting member 20 passes through the outer edge of the support body 14 and stops on the gap retaining hole 17 to maintain the gap therebetween, thereby preventing breakage due to friction. In addition, mounting grooves 26 are formed on both sides of the upper surface of the outer cutting member 20.

The inner cutter member 30 provided on the upper portion of the outer cutter 20 is inserted into the through cut hole 22 as shown in Figure 3 and inserted into the seating groove 12 of the supporter 14, (32) is formed so as to cut the inner mold (4) formed in the inner mold of the mold. 4 (a), the cutter assembly 32 is formed in a protruding form on the lower surface of the inner cutter 30, and the cutter base 32 is formed on the lower end surface of the cutout surface of the cellular phone case 5, (34) is formed. The cutting tool 32 can be formed independently and can be formed integrally with the finish surface 34.

A bar-shaped stopper 37 protrudes laterally from both sides of the inner cutter 30. 3, the stopper 37 is seated and supported in the mounting grooves 26 formed on both sides of the upper surface of the outer cutting member 20 and the outer cutting member 20 is held at a moment when the stopper 37 comes into contact with the mounting groove 26. [ The movement of the inner cutter member 30 is stopped.

The upper mold 40 provided at the upper portion of the outer mold cutting member 20 and the inner mold cutting member 30 is provided to face the lower mold 10 and has a rod 42 formed on the outer mold cutting member 20, And is moved up and down in the facing direction. The upward and downward movements are resiliently actuated by the multiple elastic springs 51 in Fig. 1, and the gap between the upper frame 40 and the lower frame 10 is maintained by the plurality of gap retaining openings 52 do.

As shown in FIG. 6, when the mobile phone case 5 is primarily formed, the outer shape burr 3 and the inner shape bar 4 are formed due to the nature of the injection molding. To solve this problem, the outer shape cutting member 20 and the inner shape cutting member 30 So that the outer burr 3 and the inner bottom 4 can be removed at one time and the surface of the cellular phone case 5 can be cleaned at the same time.
