[0002] In the manufacturing process of mobile phone mid-frames, fixtures play a crucial role. For example, they are needed for positioning and fixing during filing, drilling, and polishing, as well as for the transfer between different processes. Traditionally, blister packs were used for transferring plastic mobile phone mid-frames because the processes used were relatively simple and the subsequent process requirements were not high; blister packs could meet production needs. However, with the rapid development of consumer electronics, consumers have increasingly higher demands for mobile phone mid-frames. A beautiful and stylish high-mirror plastic mobile phone mid-frame has been developed. However, using blister packs for the transfer of high-mirror plastic mobile phone mid-frames between different processes can lead to scratches, dents, and dirt on the mirror surface, seriously affecting the appearance and process yield. Therefore, developing a reliable and practical transfer fixture is of great significance. Utility Model Content

Detailed Implementation

[0019] To further illustrate the technical means and effects of this utility model in order to achieve its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0020] Please see Figures 1 to 3 As shown, this utility model discloses a universal fixture for manufacturing high-gloss mobile phone frames, including a protective component. The protective component has a first housing 1 and a second housing 2 detachably connected to the first housing 1. The first housing 1 and the second housing 2 are closed to form a receiving cavity, in which the external mobile phone frame is located. The side of the first housing 1 facing the external mobile phone frame is provided with a first support post 31, and the side of the second housing 2 facing the external mobile phone frame is provided with a second support post 32. The first support post 31 and the second support post 32 respectively abut against the two sides of the external mobile phone frame that are far apart from each other. The first support post 31 and the second support post 32 cooperate to fix the external mobile phone frame in the receiving cavity.

[0021] In actual use, the first housing 1 and the second housing 2 of the protective component are separate units, formed by injection molding. The external mobile phone frame is located inside the receiving cavity of the protective component. The first support column 31 and the second support column 32 are located on the inner wall of the receiving cavity, respectively abutting against the two sides of the external mobile phone frame. The first support column 31 and the second support column 32 are staggered. The external mobile phone frame is fixed in the protective component by the extrusion force generated by the first support column 31 and the second support column 32 on both sides, preventing the external mobile phone frame from sliding inside the protective component and causing damage during turnover.

[0022] Furthermore, there are multiple first support columns 31, and the surface of the first support column 31 that contacts the external mobile phone frame is a smooth arc surface; there are multiple second support columns 32, and the surface of the second support column 32 that contacts the external mobile phone frame is a smooth arc surface.

[0023] In actual use, there are four first support pillars 31 and four second support pillars 32, which respectively abut against the four corners of the outer mobile phone frame. The first support pillar 31 is cylindrical, and the connecting post between the first support pillar 31 and the protective component is thickened. The second support pillar 32 is cylindrical, and the connection point between the second support pillar 32 and the protective component is thickened. The free ends of the first support pillar 31 and the second support pillar 32 are both smooth arc surfaces to prevent scratches on the surface of the outer mobile phone frame when they come into contact with it.

[0024] Furthermore, the second housing 2 has a first positioning post 4 on the side facing the external mobile phone frame. The external mobile phone frame has a positioning hole that cooperates with the first positioning post 4. When the first positioning post 4 is inserted into the positioning hole, the first positioning post 4 protrudes out of the external mobile phone frame. At this time, the first support post 31 abuts against one side of the external mobile phone frame.

[0025] In actual use, a first positioning post 4 is provided at the upper center of the second housing 2 to facilitate identification of the beginning and end of the second housing 2. At the same time, the positioning hole of the external mobile phone frame can be quickly installed by aligning it with the first positioning post 4. The length of the first positioning post 4 is longer than the length of the first support post 31. When the first positioning post 4 passes through the positioning hole of the external mobile phone frame, the first support post 31 abuts against the external mobile phone frame, supporting the external mobile phone frame.

[0026] Furthermore, the diameter of the end of the first positioning post 4 closest to the external mobile phone frame is reduced, which facilitates quick installation of the external mobile phone frame.

[0027] In actual use, the part connecting the first positioning post 4 and the second housing 2 is cylindrical, the free end of the first positioning post 4 is conical, and the tip of the cone is a smooth arc surface. The reduced tip facilitates the installation of the positioning hole of the external mobile phone frame and the first positioning post 4, and the smooth arc surface will not scratch the external mobile phone frame.

[0028] Furthermore, the protective component is also provided with a positioning part, which has a second positioning post 51 and a third positioning post 52. The second positioning post 51 and the third positioning post 52 are respectively disposed on the first housing 1 and the second housing 2. The end of the second positioning post 51 is provided with a limiting protrusion, and the end of the third positioning post 52 is provided with a limiting recess that cooperates with the limiting protrusion. When the first housing 1 and the second housing 2 are closed, the limiting protrusion is inserted into the limiting recess.

[0029] In actual use, the positioning part is used to quickly align and install the first housing 1 and the second housing 2. There are four positioning parts, located at the four corners of the protective component. Two second positioning posts 51 and two third positioning posts 52 are located at the four corners of the second housing 2. The first housing 1 is provided with two third positioning posts 52 that cooperate with the two second positioning posts 51, and two second positioning posts 51 that cooperate with the two third positioning posts 52. A limiting protrusion is provided in the middle of the side of the second positioning post 51 facing the third positioning post 52, and a limiting recess is provided in the middle of the side of the third positioning post 52 facing the second positioning post 51. The free end of the third positioning post 52 is also provided with a groove that penetrates one end of the recess, dividing one end of the limiting recess into two semi-circular edges to increase the elasticity and adjustability of the limiting groove.

[0030] Furthermore, the protective component also has a locking part, which includes a buckle 62 and a groove 61. The buckle 62 protrudes from the body of the second housing 2 and extends toward the first housing 1. The first housing 1 is provided with a groove 61 that cooperates with the buckle 62. The free end of the buckle 62 is provided with a locking block. When the first housing 1 and the second housing 2 are closed, the buckle 62 extends into the groove 61, and the locking block protrudes out of the groove 61 and engages with the edge of the groove 61.

[0031] In actual use, there are four locking parts, located at the four corners of the protective component. Each of the four corners of the second housing 2 has a latch 62, with reinforcing ribs at the connection between the latch 62 and the second housing 2 to prevent repeated opening and closing of the upper and lower housings from causing the latch 62 to break off, thus extending the service life of the protective component. The four slots 61 are four through holes located at the four corners of the first housing 1. The latches 62 extend from these through holes and are engaged with the edge of the through hole by a locking block at the end of the latch 62, thereby locking the first housing 1 and the second housing 2 together.

[0032] In actual use, the buckle can also be set on the first housing, and the slot can be set in the corresponding position on the second housing.

[0033] Furthermore, the end of the card block near the second housing 2 is provided with a boss, and the end of the card block away from the second housing 2 is provided with a guide slope. After the card block slides out of the card slot 61 via the guide slope, the boss is engaged at the edge of the card slot 61.

[0034] In actual use, the card block protrudes from one side of the buckle 62 and has an inclined surface. When the first housing 1 is close to the second housing 2, the inclined surface contacts the card groove 61 first. The buckle 62 is slightly deformed, causing the card block to slide out of the card groove 61 through the guide inclined surface and be engaged at the edge of the card groove 61.

[0035] Furthermore, the slot 61 is a through hole formed by bending the edge of the first housing 1 toward the second housing 2, and when the buckle 62 is inserted into the slot 61, the buckle 62 does not protrude out of the protective member.

[0036] In actual use, the four slots 61 are located at the four corners of the first housing 1, and the four corners of the first housing 1 are bent toward the second housing 2, so that the position of the slots 61 is closer to the second housing 2 than the first housing 1. At this time, when the buckle 62 protrudes out of the slot 61 and the buckle is engaged with the edge of the slot 61, the length of the buckle 62 will not exceed the thickness of the first housing 1, keeping the two sides of the protective part flat, facilitating transportation, and preventing the buckle 62 from breaking under force during turnover.

[0037] Furthermore, the protective component is hollow and has a reinforcing support column 7. One end of the reinforcing support column 7 protrudes from the first housing 1, and the other end of the reinforcing support column 7 forms a free end for contacting the second housing 2.

[0038] In actual use, the protective component is hollow overall. The first shell 1 and the second shell 2 each have four horizontal ribs and four vertical ribs. The first positioning post 4, the second positioning post 51, the third positioning post 52, the buckle 62, the first support post 31, and the second support post 32 are distributed on these four horizontal ribs and four vertical ribs, respectively. There are two vertical ribs on each side of the first shell 1, and a reinforcing support post 7 is provided on it. When the first shell 1 and the second shell 2 are closed, the reinforcing support post 7 abuts against the second shell 2. When the protective component is subjected to external pressure, the reinforcing support post 7 can give the protective component a certain rigidity.

[0039] In actual use, the reinforcing support column 7 can also have one end protruding onto the second shell, while the free end formed at the other end abuts against the first shell 1.

[0040] Furthermore, the first housing 1 is provided with an identification part 8. When the first housing 1 covers the second housing 2, the identification part 8 is used to distinguish the head and tail of the first housing 1.

[0041] In actual use, the first housing 1 is provided with an identification part 8 at the position corresponding to the first positioning post 4. That is, the identification part 8 is located at the upper part of the first housing 1. During installation, the head and tail of the first housing 1 can be distinguished in sequence through the identification part 8, so that the first housing 1 and the second housing 2 can be quickly matched and installed.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
