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

[0002] In the field of injection mold technology, the production quality and efficiency of mobile phone cases have always been key concerns for the industry. With the widespread adoption of smartphones and the rapid pace of upgrades, the market demand for mobile phone cases has not only increased significantly in quantity, but also in terms of quality and functionality.

[0003] Traditional injection molds for mobile phone cases present numerous problems in practical use. Firstly, some mold structures have poor sealing performance, making them prone to material leakage during injection molding. This affects the molding precision of the phone case, resulting in larger dimensional deviations, appearance defects, increased scrap rates, and higher production costs. Secondly, demolding methods are not convenient or efficient, mostly relying on manual demolding. This is not only labor-intensive, but inconsistencies in manual operation can also damage the phone case, affecting product quality and limiting production efficiency.

[0004] Therefore, a mobile phone protective case injection mold is proposed. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a mobile phone protective case injection mold to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mobile phone protective case injection mold, including a bottom template, a first module installed on the bottom template, a second module vertically arranged at one end of the first module, a third module vertically arranged at one end of the second module, a fourth module vertically arranged at one end of the third module, an upper module arranged above the bottom template, and an injection port arranged at the middle of the top of the upper module.

[0007] Preferably, the third module includes a first electric actuator, a first template, a first guide rod, a first edge banding strip, and a first sealing strip. The telescopic end of the first electric actuator is connected to the first template. Two first guide rods are symmetrically connected to one side of the first template. The two first guide rods are slidably connected to a first fixing block. A first edge banding strip is provided at the top of the other side of the first template, and a first sealing strip is provided at the bottom of one side of the first edge banding strip.

[0008] Preferably, the first module and the third module have the same structure, wherein a first insert block is provided on one side of the first template in the third module.

[0009] Preferably, a first slot is provided on one side of the upper module, the first plug is inserted into the first slot, and two protrusions are provided on one side of the first slot.

[0010] Preferably, the fourth module includes a second electric actuator, a second template, a second guide rod, a second edge banding strip, and a second sealing strip. The telescopic end of the second electric actuator is connected to the second template. Two second guide rods are symmetrically arranged on one side of the second template. The two second guide rods are slidably connected to a second fixing block. A second edge banding strip is provided at the top of the other side of the second template. A second sealing strip is connected to the bottom of one side of the second edge banding strip.

[0011] Preferably, the second module and the fourth module have the same structure, wherein a plurality of second insert blocks are provided on one side of the second template in the fourth module.

[0012] Preferably, the upper module has a plurality of second slots on one side, and each second plug is inserted into the corresponding second slot.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. The sealed fit between the various modules of the mold can effectively prevent material leakage during the injection molding process, ensure the molding accuracy of the mobile phone case, make its dimensions more precise and its appearance smoother, and reduce defects and scrap rate.

[0015] 2. Through the telescopic movement of the first electric push rod and the second electric push rod, the first template, the second template, and the edge strip and sealing strip on them are driven to automatically pull them off the upper module after the mobile phone protective case is formed.

[0023] 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.

[0024] As shown in Figures 1-4, a mobile phone protective case injection mold includes a bottom template 1, a first module 2 installed on the bottom template 1, a second module 3 vertically arranged at one end of the first module 2, a third module 4 vertically arranged at one end of the second module 3, a fourth module 5 vertically arranged at one end of the third module 4, an upper module 6 arranged above the bottom template 1, and an injection port 7 arranged at the middle of the top of the upper module 6.

[0025] In practice, the upper module 6 descends to the processing position, and the first module 2, the second module 3, the third module 4, and the fourth module 5 move closer to the upper module 6 and connect with each other. Together with the bottom template 1, they form a cavity with the injection port 7 as the opening. The structure of the cavity is the same as that of the mobile phone case. After the raw material is injected through the injection port 7 and cooled and solidified, the first module 2, the second module 3, the third module 4, and the fourth module 5 move towards the upper module 6, simultaneously pulling the formed mobile phone case down from the upper module 6. The upper module 6 then rises and resets, achieving automatic demolding. This allows the formed mobile phone case to be removed. The entire structure is sealed and fitted, improving the processing accuracy of the mobile phone case and the ease of demolding, thereby increasing processing efficiency.

[0026] The third module 4 includes a first electric actuator 401, a first template 402, a first guide rod 403, a first edge banding strip 404, and a first sealing strip 405. The telescopic end of the first electric actuator 401 is connected to the first template 402. Two first guide rods 403 are symmetrically connected to one side of the first template 402. The two first guide rods 403 are slidably connected to a first fixing block 8. The top of the other side of the first template 402 is provided with a first edge banding strip 404, and the bottom of one side of the first edge banding strip 404 is provided with a first sealing strip 405.

[0027] The first module 2 and the third module 4 have the same structure. The first template 402 in the third module 4 is provided with a first insert block 9 on one side.

[0028] The upper module 6 has a first slot 12 on one side, and the first plug 9 is inserted into the first slot 12. Two protrusions 13 are provided on one side of the first slot 12.

[0029] The fourth module 5 includes a second electric push rod 501, a second template 502, a second guide rod 503, a second edge banding strip 504, and a second sealing strip 505. The telescopic end of the second electric push rod 501 is connected to the second template 502. Two second guide rods 503 are symmetrically arranged on one side of the second template 502. The two second guide rods 503 are slidably connected to a second fixing block 10. The top of the other side of the second template 502 is provided with a second edge banding strip 504. The bottom of one side of the second edge banding strip 504 is connected to a second sealing strip 505.

[0030] The second module 3 and the fourth module 5 have the same structure, wherein the second template 502 in the fourth module 5 is provided with a plurality of second insert blocks 11 on one side.

[0031] The upper module 6 has a plurality of second slots 14 on one side, and each second plug 11 is respectively plugged into the corresponding second slot 14.

[0032] In specific implementation, during the processing of the mobile phone protective case, the upper module 6 is lowered to the processing position, and each of the first electric push rods 401 and the second electric push rod 501 is extended, so that each of the first templates 402 and the second templates 502 moves closer to the upper module 6, so that each of the first edge strips 404 and the second edge strips 504 moves to the upper edge of the upper module 6 and is connected end to end. Similarly, the first sealing strip 405 and the second sealing strip 505 at the bottom slide to the top surface of the upper module 6. At the same time, the first insert 9 is inserted into the first slot 12, and each of the second inserts 11 is inserted into the corresponding second slot 14, thereby forming a cavity with the injection port 7 as the opening. Then, the raw material is injected from the injection port 7, and after cooling and solidification, the mobile phone protective case is formed, completing the molding process of the mobile phone protective case.

[0033] Then, each of the first electric push rods 401 and the second electric push rod 501 retracts, causing the first sealing strip 405 at the bottom of the first edge banding strip 404 and the second sealing strip 505 at the bottom of the second edge banding strip 504 to pull the edge of the formed mobile phone protective case outward, thereby automatically detaching it from the upper module 6, completing the automatic demolding of the mobile phone protective case. The processed mobile phone protective case, through the setting of various plugs and sockets, has various openings on the mobile phone protective case. Each opening is aligned with the charging port, speaker port, and toggle button of the corresponding mobile phone model. The setting of the protrusion 13 can form a groove inside the mobile phone protective case to facilitate the connection with the mobile phone. Similarly, multiple protrusions can be set at the bottom of the bottom template 1 to form multiple camera through holes at the bottom of the molded phone case. During demolding, due to the positioning of the bottom of the phone case by the protrusions, the edge is subjected to a certain tension and deforms, separating from the upper module 6. After the upper module 6 is reset, the first electric push rod 401 and the second electric push rod 501 continue to pull outward and reset. The edge of the phone case automatically separates from the gap between the edge strip and the sealing strip and returns to the bottom template 1. This achieves demolding and facilitates the removal of the demolded phone case, improving material handling convenience and thus improving processing efficiency.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
