[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0021] Example

[0022] See also Figure 1-4 , which is the first embodiment of the utility model, and provides a special flow pattern earring production mold, including a mold body 1, a flow channel 2 is opened on the surface of the mold body 1, and a top gate 3 is arranged at the end of the flow channel 2 and located on the surface of the mold body 1, and the flow channel 2 is designed to be irregular streamlined.

[0023] Specifically, a first mold cavity 4 is opened at one end of the flow channel 2 and located on the surface of the mold body 1 , and a small earring 5 is arranged inside the first mold cavity 4 .

[0024] Furthermore, by opening a first cavity 4 on the surface of the mold body 1 and providing small earrings 5, multiple small earrings 5 ​​can be produced simultaneously. This multi-cavity design allows multiple products to be produced in one injection molding cycle, thereby significantly improving production efficiency.

[0025] Specifically, a second mold cavity 6 is provided at the other end of the flow channel 2 and on the surface of the mold body 1 , and a large earring 7 is provided inside the second mold cavity 6 .

[0026] Furthermore, similar to the first mold cavity 4, the second mold cavity 6 allows for the simultaneous production of multiple large earrings 7. This multi-cavity design can produce multiple products in one injection molding cycle, thereby significantly improving production efficiency. By precisely designing the runner 2 and the mold cavity, the flow path of the molten plastic can be optimized, waste and runner 2 residue can be reduced, and material utilization can be improved.

[0027] Specifically, the mold body 1 adopts a two-plate mold design, and a side gate is opened on the side of the mold body 1, and the diameter of the side gate is 0.8 mm.

[0028] Furthermore, the diameter of the side gate is 0.8 mm, which can accurately control the injection amount of plastic and reduce material waste at the gate. It also helps to control the dimensional accuracy and appearance quality of the product. The two-plate mold design can simplify the mold structure and reduce the number of mold parts, making the mold manufacturing, assembly and maintenance easier.

[0029] Specifically, the number of the first mold cavity 4 and the number of the second mold cavity 6 opened on the surface of the mold body 1 are both two, and the width of the runner 2 is greater than the width of the top gate 3 .

[0030] When in use, ensure that the mold body 1 is clean and free of impurities, check whether all parts of the mold are intact, install the mold body 1 on the injection molding machine, ensure that the mold body 1 is aligned with the clamping mechanism of the injection molding machine, and fix it, adjust the temperature, pressure, injection speed and other parameters of the injection molding machine according to the material properties of the small earrings 5 ​​and large earrings 7 to be produced, start the injection molding machine, heat the plastic raw material to a molten state, and inject the molten plastic into the runner 2 of the mold body 1 through the side gate. Since the runner 2 is designed to be an irregular streamline, the flow path of the plastic can be optimized, the pressure loss can be reduced, and the plastic can be evenly distributed in each mold cavity. The molten plastic passes through the runner 2 and enters the first mold cavity 4 and the second mold cavity 6 respectively. Since there are two first mold cavities 4 and two second mold cavities 6, four earrings (two small earrings 5 ​​and two large earrings 7) can be produced at the same time. Since the width of the runner 2 is greater than the width of the top gate 3, sufficient plastic flow into the mold cavity can be ensured while reducing material waste at the gate. The plastic is cooled and solidified in the mold cavity to form the required shapes of the small earrings 5 ​​and the large earrings 7.

[0031] In summary, the designed irregular streamlined flow channel 2, and the first mold cavity 4 and the second mold cavity 6 with specific shapes can effectively reduce the flow discrimination and holding pressure of the material, thereby improving the molding accuracy, reducing stress concentration points, and improving the overall quality of the finished product. By setting the top edge gate 3, it is easy to control the flow of the injected material, and at the same time facilitate the cooling and removal of the material at the gate, reducing the post-processing workload and improving the appearance quality of the product. At the same time, the mold design includes two mold cavities of different sizes, which are used for small earrings 5 ​​and large earrings 7 respectively, and has the ability to provide two product sizes for one molding.
