Detailed Implementation

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] This utility model provides an embodiment of a mobile phone protective case mold, such as... Figures 1 to 3 As shown, the system includes: a first inner mold 1, a second inner mold 2, and an outer mold 3; the first inner mold 1 has a groove 12, and the second inner mold 2 has a boss 25; the first inner mold 1 and the second inner mold 2 are detachable, and when combined, the boss 25 is located in the groove 12; the outer mold 3 has an injection hole 32; wherein, the edges of the groove 12 and the boss 25 form a seal, and a gap is formed in the middle; the first inner mold 1 has a heat dissipation hole 13, which communicates with the gap; in use, the lower end of the first inner mold 1 is embedded in the outer mold 3, so that the lower side of the first inner mold 1 corresponds to the side of the outer mold 3; the bottom surface of the second inner mold 2 corresponds to the bottom surface of the outer mold 3. In use, the first inner mold 1 and the second inner mold 2 are combined, and then combined with the outer mold 3, and injection molding is performed through the injection hole 32.

[0027] In this embodiment, the first inner mold 1 and the second inner mold 2 are detachable and are sealed and form gaps through the cooperation of the boss 25 and the groove 12. Heat can be easily dissipated through the heat dissipation holes 13. Multiple heat dissipation holes 13 can be provided to allow for external liquid cooling equipment to be connected, thereby accelerating heat dissipation. During the injection molding process, heat can be transferred to the heat dissipation holes 13 through the gaps and then dissipated. This ensures uniform cooling of the plastic within the mold, avoiding quality problems in the phone case caused by heat accumulation, such as reducing deformation and surface unevenness, thus improving product quality and production efficiency. Since the first inner mold 1 and the second inner mold 2 are detachable, if one of the inner molds is damaged or worn, only the corresponding part needs to be replaced, unlike traditional molds which may require replacing the entire inner mold or both upper and lower molds. This further reduces maintenance costs and improves equipment availability.

[0028] In one embodiment of this application, the surface of the second inner mold 2 is provided with a lens protrusion 21 and a lamp hole 22; the outer mold 3 is provided with a corresponding lens groove 31.

[0029] A lens protrusion 21 and a lamp hole 22 are provided on the surface of the second inner mold 2, while the outer mold 3 is provided with a corresponding lens groove 31. This can precisely reserve the position of the corresponding mobile phone lens and flash and other components for the mobile phone case, ensuring that the mobile phone's photography, fill light and other functions will not be blocked or affected when using the case, thus improving the practicality and adaptability of the mobile phone case.

[0030] When producing protective cases for mobile phones with complex rear camera modules such as multi-camera configurations and ring flash, such as a flagship phone of a certain brand, whose rear camera module protrudes and is uniquely arranged, and whose flash shape is also quite special, the lens protrusion 21, the lamp hole 22 and the lens slot 31 precisely designed in this solution can create a protective case that perfectly fits this phone, without affecting the phone's original photography and fill light functions, and also making the phone look exquisite after the protective case is put on.

[0031] In one embodiment of this application, a logo mark 11 is provided on the side of the lower end of the first inner mold 1.

[0032] By setting the logo mark 11 on the side of the lower end of the first inner mold 1, the phone case will have the corresponding brand logo after injection molding, which can enhance brand recognition and awareness, allowing users to naturally display the brand during use. In addition, different brands or different series of products of the same brand can be differentiated by setting unique logo marks 11, meeting users' needs for personalized and branded protective cases.

[0033] In one embodiment of this application, the first inner mold 1 is provided with a first mounting hole 14, and the second inner mold 2 is provided with a corresponding second mounting hole 24.

[0034] By providing a first mounting hole 14 in the first inner mold 1 and a corresponding second mounting hole 24 in the second inner mold 2, it is convenient to accurately and securely connect the two inner molds using appropriate connectors such as bolts during mold production, assembly, and subsequent possible maintenance. This ensures accurate relative positioning between the inner molds, maintains the stability of the overall mold structure, and improves the cost-effectiveness of the mold.

[0035] In the long-term, large-scale production of a popular mobile phone case, the mold needs to be opened and closed frequently for injection molding. Since the first inner mold 1 and the second inner mold 2 are securely connected through the first mounting hole 14 and the second mounting hole 24, even after multiple cycles of use, the two inner molds can still maintain a good fit, reducing mold damage caused by loosening and other problems, and ensuring smooth production.

[0036] In one embodiment of this application, a button protrusion 15 is provided on the side of the lower end of the first inner mold 1. Providing the button protrusion 15 on the side of the lower end of the first inner mold 1 allows for adequate space to be reserved for the physical buttons of the mobile phone on the protective case. Furthermore, the shape and height of the button protrusion 15 can be designed to allow users to press the physical buttons more accurately and comfortably when using a mobile phone with a protective case, without affecting the original button functions and tactile feedback of the mobile phone.

[0037] For some gaming phones, the physical buttons on the side are crucial for game operation. When producing protective cases for these phones, the button protrusions 15 are used to precisely reserve the appropriate space and tactile feedback for the shoulder buttons and other buttons on the gaming phone. This allows players to continue playing games smoothly even after putting on the protective case, which will undoubtedly increase the popularity of the protective case among gamers.

[0038] In one embodiment of this application, the second inner mold 2 is further provided with a hollow groove 23 at the position facing the groove 12; the position opposite to the groove 12 and the hollow groove 23 is hollow.

[0039] The second inner mold 2 is provided with a hollow groove 23 facing the groove 12, and the opposite position of the groove 12 is hollow. The reasonable hollow design can reduce the weight of the mold while ensuring the strength and function of the protective shell, thereby reducing production costs and improving production efficiency.
