[0039] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0040] like Figures 1 to 4 As shown, an embodiment of the utility model provides a charger shell injection mold, including an upper template 1, a lower template 2, a base plate 3 and a sliding mechanism 4, the base plate 3 is arranged at the bottom of the lower template 2, the upper template 1 is arranged above the lower template 2, the bottom of the upper template 1 is provided with an upper mold core, the top of the lower template 2 is provided with a lower mold core 20, an injection cavity for molding a charger shell is formed between the upper mold core and the lower mold core 20, and the two sliding mechanisms 4 are respectively arranged on the lower template 2 on both sides of the lower mold core 20; when the plastic raw material is heated and melted in the injection molding machine, it can enter the injection cavity by high-pressure injection, thereby filling the entire space, and solidify and mold after cooling, and finally obtain the shape and structure of the charger shell; the sliding mechanism 4 can assist in demolding the charger shell with a charging slot to avoid product damage or defects.

[0041] like Figures 5 to 8 As shown, the sliding mechanism 4 includes a fixed seat 41, a sliding seat 42, a sliding shovel base 43, a limit block 44 and a hook assembly 45, the fixed seat 41 is arranged on the lower template 2, the sliding seat 42 is arranged on the fixed seat 41, and the sliding seat 42 is provided with a clamping groove 421 on the side close to the lower mold core 20, the top of the sliding seat 42 is provided with an inclined hole 422, and an inclined guide column (not shown) is provided in the inclined hole 422, the top of the inclined guide column is connected to the upper template 1, and the sliding seat 42 can move along with the inclined guide column The lifting and lowering drive the clamping groove 421 away from or close to the lower mold core 20; the shape of the clamping groove 421 is adapted to the shape of the charger shell, and the clamping grooves 421 of the sliding seats 42 on both sides of the lower mold core 20 are closed to surround the lower mold core 20. When the charger shell product is completed and the mold needs to be opened, the upper mold plate 1 moves upward and drives the sliding seat 42 to move away from the lower mold core 20 through the inclined guide column, so that the clamping groove 421 is away from the lower mold core 20, so that the ejector mechanism under the mold can eject the charger shell upward to demold the product.

[0042] A slide groove 423 is provided on the side of the sliding seat 42 away from the lower mold core 20, and the slide groove 423 is connected to the sliding seat 46 and the sliding seat 43 is provided with a travel limit groove 431 at the bottom, and a stopper 411 for abutting against the travel limit groove 431 is provided on the fixed seat 41; the sliding seat 43 can limit the movement process of the sliding seat 42 away from the lower mold core 20. Specifically, when the sliding seat 42 moves, the sliding seat 43 can be driven to move together by the connecting slider 46 until the travel limit groove 431 abuts against the stopper 411, so as to avoid the sliding seat 42 moving away from the lower mold core 20 too large and causing the mold structure to be unstable.

[0043] The bottom of the slider seat 42 is provided with a first accommodating cavity 424, the hook assembly 45 is provided in the first accommodating cavity 424, the first accommodating cavity 424 extends with a second accommodating cavity 425 in the direction of the lower mold core 20, the top of the limit block 44 is located in the second accommodating cavity 425, and is used to limit and abut with the hook assembly 45, and the bottom of the limit block 44 passes through the lower mold plate 2 and is connected to the bottom plate 3.

[0048] like Figure 6 and Figure 7 As shown, further, an anti-slip limit groove 4230 is further provided in the slide groove 423, and an anti-slip protrusion 462 is provided on the connecting slider 46 for being adapted and engaged with the anti-slip limit groove 4230. The provision of the anti-slip protrusion 462 and the anti-slip limit groove 4230 can prevent the connecting slider 46 from slipping out of the slide groove 423, and the structural stability is high.

[0049] like Figure 4 and Figure 6 As shown, further, a second positioning protrusion 412 is provided at the bottom of the fixing seat 41, and a second positioning groove 21 for adapting and connecting with the second positioning protrusion 412 is provided on the lower template 2. Such a configuration can improve the assembly convenience between the fixing seat 41 and the lower template 2.

[0050] like Figure 5As shown, further, the side wall of the slider seat 42 located on one side of the lower mold core 20 is provided with a third positioning protrusion 426, and the side wall of the slider seat 42 located on the other side of the lower mold core 20 is provided with a third positioning groove 427, and the third positioning groove 427 is used to position and snap-fit ​​with the third positioning protrusion 426 when the mold is in a closed state, so as to avoid displacement or misalignment of the mold when the mold is closed, thereby improving the molding accuracy of the injection molded part of the charger shell.
