Description

Technical Field

[0001] This utility model relates to the field of injection molding mold technology, specifically to an injection molding mold for a mobile phone protective case. Background Technology

[0002] With the widespread use of mobile phones, phone cases, as accessories that protect and decorate phones, have a huge market demand. In existing injection molding molds for phone cases, side core-pulling mechanisms are typically used to mold phone cases with side grooves and other structures.

[0003] There are numerous mobile phone models on the market, but even within the same brand, some different models have similar overall dimensions and shapes, with differences mainly in the placement of the camera port, buttons, and interfaces. This necessitates the production of phone cases in various sizes. However, most molds with side-pulling core structures can only produce phone cases of a single size. When different sizes of phone cases need to be produced, the entire mold often needs to be replaced, resulting in high costs and low production efficiency. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 This utility model provides a technical solution for injection molding of mobile phone protective cases: including a fixed mold base 1, a moving mold base 2, and a side core pulling mechanism. A fixed template 3 is fixedly installed on the fixed mold base 1, and a moving template 5 is fixedly installed on the moving mold base 2. A cavity 4 is formed between the fixed template 3 and the moving template 5. The cavity 4 is used to mold the mobile phone case. The side core pulling mechanism includes a side slider 6, an inclined guide post 7, and a limiting block 19. The inclined guide post 7 is fixed on the fixed mold base 1. The side slider 6 is provided with an inclined guide hole 8 that slides and cooperates with the inclined guide post 7. The inclined guide post 7 passes through the fixed template 3 and is fixedly connected to the fixed mold base 1. An ejection mechanism is also provided below the moving mold base 2.

[0027] Combination Figure 4 , Figure 5 as well as Figure 6 As shown, a core unit block is provided in the cavity 4. The core unit block includes an upper unit block 9 that can be detachably installed on one side of the fixed template 3 and a lower unit block 10 that can be detachably installed on one side of the moving template 5. The core unit block is used to form the camera hole of the mobile phone case.

[0028] Specifically, a screw can be used to pass through the side of the fixed template 3 opposite to the upper unit block 9 and be fixedly connected to the upper unit block 9, without penetrating the upper unit block 9. Similarly, a screw can be used to pass through the side of the moving template 5 opposite to the lower unit block 10 and be fixedly connected to the lower unit block 10, without penetrating the lower unit block 10. The upper unit block 9 and the lower unit block 10 cooperate to form a complete core structure.

[0029] Optionally, the upper unit block 9 and the lower unit block 10 can be rounded rectangles or chamfered quadrilaterals. The upper unit block 9 and the lower unit block 10, through precise fitting, ensure the accuracy and consistency of the camera hole position on the phone case. Because the core unit blocks are detachable and installable, when it is necessary to replace them with different specifications to adapt to the production of different phone case models, operators only need to simply remove the original core unit block and install the corresponding specification core unit block, greatly saving mold changeover time and improving production efficiency.

[0030] Combination Figure 3 As shown, a molding insert is provided on the side of the side slider 6 near the cavity 4. The molding insert can be detachably installed on the side slider 6, and the shape of the molding insert matches the structure of the side of the phone case that needs to be core-pulled. By replacing molding inserts of different shapes, the molding requirements of the side structure of phone cases of different specifications can be adapted.

[0031] Combination Figure 2 As shown, a guiding mechanism is provided between the fixed template 3 and the moving template 5. The guiding mechanism includes a guide post 12 and a guide sleeve 13. The guide post 12 is fixedly installed on the fixed template 3, and the guide sleeve 13 is fixedly installed on the moving template 5. The guide sleeve 13 and the guide post 12 slide together to ensure accurate alignment of the fixed template and the moving template during the mold closing and opening process.

[0032] Combination Figure 4As shown, the ejection mechanism includes an ejector plate 14, an ejector pin 15, and a return spring 16. The ejector plate 14 is slidably mounted on the moving mold base 2. One end of the ejector pin 15 is fixed to the ejector plate 14, and the other end extends through the moving mold plate 5 into the cavity 4. The two ends of the return spring 16 abut against the ejector plate 14 and the moving mold base 2, respectively. After injection molding is completed, the ejection mechanism starts to work. The ejector plate 14 slides on the moving mold base 2, driving the ejector pin 15 to move, so that the other end of the ejector pin 15 ejects the molded mobile phone shell from the cavity 4, realizing automatic demolding of the product. At the same time, the return spring 16 plays a role in buffering during the ejection process and in the sliding return of the ejector pin 15, ensuring that the ejector plate 14 and the ejector pin 15 can return smoothly, preparing for the next injection molding.

[0033] Combination Figure 5 As shown, the fixed template 3 is also equipped with a phone case back molding component, which includes a fixed frame 17 and several component blocks 18. The molding blocks 18 are detachably connected to the fixed frame 17. The fixed template 3 is provided with a mounting groove 20 for mounting the fixed frame 17, and the fixed frame 17 is embedded in the mounting groove 20. The phone case back molding component allows phone cases with different patterns to be produced on the same mold, simply by replacing different molding blocks 18, greatly improving the mold's compatibility and applicability. The detachable connection between the molding blocks 18 and the fixed frame 17 makes replacing the molding blocks 18 simple and quick, reducing production costs and operational difficulty.

[0034] Combination Figure 5 As shown, a limiting block 19 is fixedly installed on one side of the fixed frame 17, and a limiting groove 21 matching the limiting block 19 is provided on one side of the mounting groove 20. The molding block 18 has a T-shaped structure, and a slot 22 for installing the molding block 18 is provided inside the fixed frame 17. The top two sides of the slot 22 are provided with support grooves 11. The T-shaped head of the molding block 18 is engaged in the slot 22, while the T-shaped rod rests on the support groove 11. This not only facilitates the quick installation and removal of the molding block 18, but also ensures the stability of the molding block 18 after installation, avoiding displacement during injection molding and affecting the molding quality of the phone case.

[0035] Working Principle: During use, first assemble all parts of the mold, ensuring that the cavity 4 between the fixed mold plate 3 and the moving mold plate 5 accurately corresponds to the shape of the phone case. Through the cooperation of the inclined guide post 7 and the side slider 6 of the side core-pulling mechanism, the side structure of the phone case is formed by core pulling. After injection molding, the ejection mechanism ejects the formed phone case from the cavity 4 for easy removal. Since the core unit block includes detachable upper unit block 9 and lower unit block 10, and the molding block 18 is also detachably connected to the fixed frame 17, the corresponding core unit block and molding block 18 can be quickly replaced according to different specifications of phone cases without replacing the entire mold. This allows for the production of various phone cases with only minor local differences, greatly improving production efficiency and reducing production costs.
