It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0032] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0033] like Figures 1 to 7 As shown, the embodiment of the utility model provides an earphone shell mold that can be demoulded quickly, including a top seat 8, an upper mold seat 1, a lower mold seat 2, a base 3, an ejector mechanism 4, an inserting needle 5, a first slide mechanism 6 and a second slide mechanism 7;

[0034] The top seat 8 is arranged on the top of the upper mold base 1, and the upper mold base 1 is arranged on the top of the lower mold base 2. A cavity mold core 10 is provided at the bottom of the upper mold base 1, and a core mold core 20 is provided at the top of the lower mold base 2. A molding chamber for injection molding an earphone shell product is formed between the cavity mold core 10 and the core mold core 20; when the upper mold base 1 and the lower mold base 2 are closed, the gap between the cavity mold core 10 and the core mold core 20 forms a molding chamber. During the injection molding process, the molten plastic is injected into the molding chamber through the injection system, filling the entire space, and forming an earphone shell product after cooling.

[0035] The bottom of the lower mold base 2 is connected to the base 3 via 31, and the ejector mechanism 4 is disposed between the lower mold base 2 and the base 3. The ejector mechanism 4 is used to eject the completed earphone shell product upward; during the demolding process, the ejector mechanism 4 can apply force upward to eject the molded earphone shell product from the molding chamber of the mold to ensure that the product can be demolded smoothly. It should be noted that the ejector mechanism 4 is a publicly available prior art, and the specific structure and working principle of the ejector mechanism 4 will not be described in detail here.

[0036] The first slide mechanism 6 is arranged at the bottom of the upper mold base 1, and the second slide mechanism 7 is arranged at the top of the lower mold base 2. The insert pin 5 is obliquely arranged between the first slide mechanism 6 and the second slide mechanism 7, and the top of the insert pin 5 is connected to the top seat 8. The bottom of the insert pin 5 is used to extend into the molding chamber or be pulled out from the molding chamber along with the demolding action of the top seat 8; the insert pin 5 can form a speaker hole structure inside the earphone shell product. The insert pin 5 is arranged between the first slide mechanism 6 and the second slide mechanism 7, which can limit the lateral deviation of the insert pin 5 during the demolding process, thereby avoiding deformation or damage of the product due to movement deviation of the insert pin 5.

[0037] like Figure 2 , Figure 6 and Figure 7 As shown, the first sliding mechanism 6 includes a first inclined lift block 61 and a first slide 62, the upper mold base 1 is provided with an inclined first slide groove 101, the first slide 62 is arranged in the first slide groove 101, the first slide 62 is provided with a first inclined hole 620, the bottom of the first inclined lift block 61 is arranged in the first inclined hole 620, and the first inclined lift block 61 is connected to the top seat 8, and the first inclined lift block 61 is used to push the first slide 62 to move along the first slide groove 101 as the top seat 8 is demoulded. Before the injection molding begins, the upper mold base 1 and the lower mold base 2 are closed, and a molding chamber is formed between the cavity mold core 10 and the core mold core 20. At this time, the insert pin 5 is located in the molding chamber, the first slide 62 is in the initial position in the first slide groove 101, and the first inclined ejector block 61 is located in the first inclined hole 620. When the injection molding is completed, the upper mold base 1 starts to rise and performs the demolding action. During the rising process of the top seat 8, the first inclined ejector block 61 fixed on the top seat 8 also rises accordingly, and at the same time pushes the first slide 62 to move outward along the inclined first slide groove 101. During the movement of the first slide 62 along the first slide groove 101, it will drive the insert pin 5 to move synchronously. The bottom of the insert pin 5 is pulled out of the molding chamber with the movement of the first slide 62, ensuring smooth demolding of the product and avoiding lateral deviation.

[0038] like Figure 2 , Figure 6 and Figure 7As shown, further, the second slide mechanism 7 includes a second inclined top block 71 and a second slide 72, the lower die base 2 is provided with an inclined second slide groove 201, the second slide 72 is arranged in the second slide groove 201, the second slide 72 is provided with a second inclined hole 720, the bottom of the second inclined top block 71 is arranged in the second inclined hole 720, and the second inclined top block 71 is connected to the upper die base 1, and the second inclined top block 71 is used to push the second slide 72 to move along the second slide groove 201 as the upper die base 1 moves up and down. It should be noted that the working principle of the second slide mechanism 7 is the same as that of the first slide mechanism 6, and will not be described in detail here.

[0039] like Figure 7 As shown, further, the first slide 62 and the second slide 72 are provided with arc-shaped clamping openings 600 on the side walls close to the insert pin 5, and the arc-shaped clamping openings 600 are used to position and clamp the insert pin 5. The arc-shaped clamping openings 600 can accurately fix the position of the insert pin 5, ensure that it maintains accurate positioning during the molding and demoulding process, prevent the insert pin 5 from increasing the contact area with the product due to deviation, and thus reduce the adhesion phenomenon.

[0040] like Figure 4 and Figure 6 As shown, further, the first sliding mechanism 6 also includes a first pressure plate 63, and the two first pressure plates 63 are arranged on both sides of the first slide 62. The first pressure plate 63 is used to limit the lateral deviation of the first slide 62 to ensure that the first slide 62 remains stable when moving along the first slide groove 101, and prevents the first slide 62 from being deflected due to lateral force, thereby ensuring the precise movement trajectory of the insert needle 5.

[0041] like Figure 3 and Figure 6 As shown, further, the second slide mechanism 7 also includes a second pressing plate 73, two second pressing plates 73 are arranged on both sides of the second slide 72, and the second pressing plates 73 are used to limit the lateral deviation of the second slide 72. It should be noted that the working principle of the second pressing plate 73 is the same as that of the first pressing plate 63, and no further details are given here.

[0042] like Figure 2 and Figure 6 As shown, further, a needle fixing seat 51 is included, the needle fixing seat 51 is connected to the top seat 8, and the top of the needle 5 is connected to the needle fixing seat 51. The setting of the needle fixing seat 51 makes the assembly and disassembly of the needle 5 more convenient, reduces the downtime due to mold maintenance and maintenance, and improves work efficiency.

[0043] like Figure 3As shown, further, a receiving groove 200 is provided on the top of the lower mold base 2, the core mold core 20 is located in the receiving groove 200, and a third sliding groove 202 is provided on the end surface of the core mold core 20 for the second slide seat 72 to slide into. The third sliding groove 202 is provided so that the second slide seat 72 can move along a set track, thereby promoting the insert pin 5 to accurately extend and withdraw during the molding and demoulding process.

[0044] like Figure 3 As shown, further, a avoidance hole 203 for the second lift block 71 to be lifted is provided in the second slide groove 201. The setting of the avoidance hole 203 can prevent the second lift block 71 from interfering with other mold parts during the lifting movement, thereby avoiding mold failure caused by movement obstruction.

[0045] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents.
