Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone backplane forming, in particular to a mobile phone backplane forming device with adjustable size. Background Technique

[0002] A mobile phone, also known as a mobile telephone or wireless telephone, is usually called a mobile phone. It was originally just a communication tool and was commonly known as the "big brother" in the early days. It is a portable telephone terminal that can be used in a relatively wide range. It was originally developed from the battlefield mobile telephone manufactured by Bell Labs in 1940. With the development of technology, more and more smart phones have emerged. The mobile phone backplane is a small structural part covering the back of the smart phone and is usually made of materials such as plastic, metal or glass. Its main function is to protect the electronic components and components such as cameras inside the mobile phone, and at the same time, it can also play a role in beautifying the appearance of the mobile phone. For the backplane, stamping is usually used. The backplane is subjected to pressure in the mold and undergoes plastic deformation to obtain the required backplane shape. Stamping can process metal backplanes with higher precision.

[0003] For example, the Chinese patent "A Rapid Forming Device for a Mobile Phone Backplane" with the publication number CN214866451U includes a stamping seat body; the stamping seat body is in a U-shaped structure rotated 90 degrees as a whole. A stamping machine is installed on the top of the stamping seat body, and a punch is connected to the bottom of the stamping machine. And a threaded hole is opened at the bottom of the punch. The outer shell is fixedly arranged on the sliding seat through adjusting screws. A driving motor is installed inside the outer shell, and a heat dissipation fan is fixedly connected to the rotating shaft of the driving motor.

[0004] Although the above-mentioned prior art can realize adjustment according to the size of the mobile phone backplane, in actual use, on the one hand, the adjustment of the mobile phone backplane mold is not flexible enough. When it is necessary to replace the mobile phone backplane molds of different sizes, the overall fixing structure needs to be removed, resulting in inflexible mold adjustment, thus increasing the workload of personnel. On the other hand, the device is difficult to buffer the impact force generated during the stamping of the mobile phone backplane production, resulting in easy damage and deformation of the workbench, thus affecting the service life of the device. Therefore, it does not meet the existing requirements. For this reason, we propose a mobile phone backplane forming device with adjustable size. Content of the Utility Model

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model can adjust the position to adapt to mobile phone back panel manufacturing molds of different sizes through the clamping plate and the first rotating rod. When the distance between the clamping plates is adjusted according to the mobile phone back panel manufacturing molds of different sizes, the first rotating rod is rotated to make the first rotating rod drive the second limiting plate to move upward, and the sliding plate is pulled out at this time, and the clamping plate fixed under the sliding plate also moves with the sliding plate. At this time, the distance between the clamping plates changes. After adjusting to a certain distance, the mobile phone back panel manufacturing mold is placed between the clamping plates on both sides, and the first rotating rod is rotated again to make the first rotating rod drive the second limiting plate to move downward until the second rubber gasket on the second limiting plate contacts and squeezes the sliding plate, so that the sliding plate is fixed, which is convenient for disassembly and assembly of the mobile phone back panel manufacturing mold, so as to adapt to mobile phone back panel manufacturing molds of different sizes and improve the adaptability of the device to different mobile phone back panel manufacturing molds.

[0018] 2. The utility model can buffer the impact force generated when the mobile phone back panel is manufactured through the damper and the support spring. When the mobile phone back panel is manufactured, the telescopic end of the first hydraulic telescopic device moves downward, driving the mobile phone back panel manufacturing mold to squeeze the fixed plate. At this time, the fixed plate squeezes the buffer plate downward. When the buffer plate is impacted, it squeezes the damper and the support spring downward to shrink the damper and the support spring. During the shrinkage process, the impact force in the vertical direction is absorbed to avoid damage and deformation of the workbench, thereby extending the service life of the device.

[0019] 3. The utility model can fix a fixed mold that matches the mobile phone back panel mold of different sizes through the second pressure-expansion device and the L-shaped fixing rod. When the fixed mold is replaced, the telescopic end of the second pressure-expansion device contracts to expand the distance between the L-shaped fixing rods, and the fixed mold is taken out from between the L-shaped fixing rods. Then, the fixed mold that matches the mobile phone back panel mold is placed between the L-shaped fixing rods. At this time, the second pressure-expansion device is turned on to extend the telescopic end of the second pressure-expansion device until the L-shaped fixing rod squeezes the fixed mold, thereby improving the adaptability of the device to mobile phone back panel molds of different sizes.
