Technical Field

[0001] This utility model belongs to the technical field of hot bending machines for mobile phone back panels, specifically relating to hot bending machines for mobile phone back panels. Background Technology

[0002] A mobile phone back panel hot bending machine is a device used to heat and soften glass and then bend it into shape. This equipment is mainly used to manufacture mobile phone back panels with curved designs to improve the aesthetics and grip of the phone.

[0003] Existing mobile phone back panel hot bending machines make it inconvenient for workers to remove the molded mobile phone back panel from the mold. Furthermore, after multiple uses, the mobile phone back panel mold is prone to sticking to the glass material that formed the mold, which may increase the difficulty of demolding, thereby increasing the demolding time for workers and reducing production efficiency. At the same time, the sticky glass material may damage the surface of the mobile phone back panel mold, affecting product quality and even affecting the forming of the next mobile phone back panel mold. Therefore, a mobile phone back panel hot bending machine is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a hot bending machine for mobile phone back panels to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hot bending machine for mobile phone back panels, comprising a hot bending machine body, a fixed platform, and a mobile phone back panel mold. The mobile phone back panel mold has an internal spraying device, which includes an installation groove. An electric telescopic rod is fixedly connected to the inner wall of the installation groove. An L-shaped limiting groove is opened inside the fixed platform. A transverse connecting plate is fixedly connected to the inner wall of the L-shaped limiting groove. A longitudinal connecting column is fixedly connected to the top of the transverse connecting plate. A release solvent push plate is slidably connected inside the mobile phone back panel mold. A release solvent storage cavity is opened inside the release solvent push plate. A lower pressure plate is slidably connected to the inner wall of the release solvent storage cavity. Several solvent spray holes are opened on the surface of the release solvent push plate. A solvent addition sealing hole is opened inside the mobile phone back panel mold. A threaded sealing plug is threadedly connected to the inner wall of the solvent addition sealing hole.

[0006] By setting up the above structure, when it is necessary to remove the molded phone back panel from the mold and spray the release agent inside the mold, the electric telescopic rod is activated to drive the release solvent push plate to rise and push the molded phone back panel to the outside of the mold, making it easier for workers to pick up the molded phone back panel. This also avoids damage to the product that may be caused by improper handling by workers. The pressure plate descends in the release solvent storage cavity opened inside the release solvent push plate and sprays the release agent stored in the release solvent storage cavity onto the inner wall of the phone back panel mold through the solvent spray hole. The release agent in the phone back panel mold can minimize the adhesion between the glass material and the inner wall of the phone back panel mold, so that the molded phone back panel mold can be demolded more smoothly. It can also reduce the demolding difficulty of the phone back panel mold while ensuring the quality of the product after demolding, thereby reducing the demolding stoppage and processing time during the production process and helping to achieve continuous and efficient production.

[0007] As a preferred embodiment, the hot bending machine body has four support legs at the bottom and a control console at the top.

[0012] As a preferred embodiment, the bottom of the lower pressure plate is fixedly connected to the top of the longitudinal connecting column, the longitudinal connecting column is slidably connected to the demolding solvent push plate, and the solvent adding sealing hole is connected to the demolding solvent storage cavity.

[0013] By setting a solvent addition sealing hole and a threaded sealing plug, the release agent can be injected into the release solvent storage cavity through the solvent addition sealing hole. At the same time, when the mobile phone back panel mold has other application scenarios, such as needing to inject lubricant into the release solvent storage cavity, different solvents can also be injected through the solvent addition sealing hole. This enhances the functionality and flexibility of the solvent addition sealing hole, thus enabling a wider range of application scenarios for the solvent addition sealing hole.
