[0024] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0025] like Figures 1 to 5 A multi-cavity injection mold shown in the figure comprises a first mold 1, a second mold 2 located below the first mold 1 and connected to the first mold 1, a plurality of product racks 3 are arranged on the second mold 2, each of the product racks 3 comprises a product mold 31 fixedly connected to the second mold 2, and a glue injection cover 32 covered on the product mold 31, a molding cavity 33 for accommodating an injection molded product is formed between the product mold 31 and the corresponding glue injection cover 32, a plurality of glue injection pipelines 11 are arranged on the first mold 1, and each of the glue injection pipelines 11 is connected to a corresponding independent molding cavity 33;

[0026] The utility model provides a multi-cavity injection mold, by arranging a plurality of independent product racks on the second mold so that the molding cavity in each product rack is relatively independent, and arranging a plurality of glue injection pipelines on the first mold, each glue injection pipeline is connected to a corresponding independent molding cavity, which is beneficial for users to inject different injection materials into the independent molding cavities through the glue injection pipelines in the same production batch, so as to obtain injection molded products of different materials in the same production batch, and effectively solves the problem that the molding cavities in the injection mold are connected to each other so that the injection molded products are all made of the same material.

[0027] By setting up independent molding cavities, the cavity structure of each independent molding cavity is different, so that users can obtain injection molded products of different shapes at the same time in the same injection molding process, which is conducive to improving the use scenarios of injection molds, effectively improving injection molding production efficiency, and saving manpower and time costs.

[0028] like Figures 1 to 5 The product rack 3 shown includes a first product rack 311 located at one side of the second mold 2, and the glue injection pipeline 11 includes a first glue injection pipeline 41 connected to the first product rack 311;

[0029] Optionally, the first product rack 311 is located on the left side of the second mold 2, which is beneficial to saving the use space of the product rack 3 on the second mold 2, so that the user can set as many product racks 3 as possible on the second mold 2, effectively improving the use quality and efficiency of the second mold 2.

[0030] Furthermore, the first glue injection pipeline 41 is connected to the first product rack 311 so that the glue injection material can flow directly into the first product rack 311 through the first glue injection pipeline 41, thereby reducing material waste during the injection molding process, helping to reduce production costs, and improving resource utilization efficiency.

[0031] Furthermore, the first glue injection pipeline 41 is connected to the first product rack 311, which can ensure that the injection parameters during the injection molding process are accurately controlled in the first product rack 311, which helps to maintain the consistency and quality of the injection molded products.

[0032] Furthermore, the overall structure of the first product rack 311 is a rectangular parallelepiped, which has good stability and rigidity and can withstand greater pressure and force during the injection molding process, thereby helping to ensure that the injection-molded products in the first product rack 311 can be smoothly molded and ensure the consistency of product size and shape.

[0033] like Figures 1 to 5The first product rack 311 shown includes a first product mold 3111 and a first glue injection cover 3112. The first product mold 3111 and the first glue injection cover 3112 enclose a first molding cavity 3113. The first glue injection pipeline 41 includes three mutually independent first upper glue injection pipelines 411, a first middle glue injection pipeline 412 and a first lower glue injection pipeline 413. The first glue injection cover 3112 is provided with a first upper glue injection hole 511 connected to the first upper glue injection pipeline 411, a first middle glue injection hole 512 connected to the first middle glue injection pipeline 412, and a first lower glue injection hole 513 connected to the first lower glue injection pipeline 413.

[0034] Optionally, the first glue injection pipeline 41 includes three independent first upper glue injection pipelines 411, first middle glue injection pipelines 412 and first lower glue injection pipelines 413, which can realize simultaneous glue injection at different positions, helping to improve injection molding efficiency, shorten injection molding cycle, and increase production output.

[0035] Furthermore, the first upper glue injection pipeline 411, the first middle glue injection pipeline 412 and the first lower glue injection pipeline 413 are independently arranged, which is conducive to the user to flexibly control the opening and closing states of different glue injection pipelines 11, thereby realizing the control of the flow of injection material in the molding cavity 33, helping to optimize the injection molding process and improve the consistency and quality of the product.

[0036] like Figures 1 to 5 The product rack 3 shown includes a second product rack 312 located in the middle of the second mold 2, and the glue injection pipeline 11 includes a second glue injection pipeline 42 connected to the second product rack 312;

[0037] Optionally, the second product rack 312 is located in the middle of the second mold 2, which helps to save the use space of the product rack 3 on the second mold 2, so that the user can set as many product racks 3 as possible on the second mold 2, effectively improving the use quality and efficiency of the second mold 2.

[0038] Furthermore, the second glue injection pipeline 42 is connected to the second product rack 312 so that the glue injection material can flow directly into the second product rack 312 through the second glue injection pipeline 42, thereby reducing material waste during the injection molding process, helping to reduce production costs, and improving resource utilization efficiency.

[0039] Furthermore, the second glue injection pipeline 42 is connected to the second product rack 312, which can ensure that the injection parameters during the injection molding process are accurately controlled in the second product rack 312, which helps to maintain the consistency and quality of the injection molded products.

[0040] Furthermore, the overall structure of the second product rack 312 is a rectangular parallelepiped, which has good stability and rigidity and can withstand the greater pressure and force during the injection molding process, helping to ensure that the injection-molded products in the second product rack 312 can be smoothly molded and ensure the consistency of product size and shape.

[0041] like Figures 1 to 5 The second product rack 312 shown includes a second product mold 3121 and a second glue injection cover 3122. The second product mold 3121 and the second glue injection cover 3122 enclose a second molding cavity 3123.

The second glue injection pipeline 42 is connected to the second molding cavity 3123 through the second glue injection hole 52.

[0042] Furthermore, by directly connecting the second glue injection pipeline 42 with the second glue injection hole 52, single-channel glue injection is achieved. Compared with the multi-channel glue injection setting, the single-channel glue injection can more accurately control the flow and filling process of the glue injection, thereby improving the consistency and quality of the product.

[0043] Furthermore, compared with the multi-channel glue injection setting, the single-channel glue injection structure is simpler, reducing the number of components and joint connections, thereby reducing the complexity of manufacturing and maintenance. At the same time, the simplified structure can also improve the stability and reliability of the injection molding process.

[0044] like Figures 1 to 5 The product rack 3 shown further includes a third product rack 313 located at one side of the second mold 2, and the glue injection pipeline 11 further includes a third glue injection pipeline 43 connected to and communicating with the third product rack 313;

[0045] Optionally, the third product rack 313 is located on the right side of the second mold 2, which is beneficial to saving the use space of the product rack 3 on the second mold 2, so that the user can set as many product racks 3 as possible on the second mold 2, effectively improving the use quality and efficiency of the second mold 2.

[0046] Furthermore, the second glue injection pipeline 43 is connected to the third product rack 313 so that the glue injection material can flow directly into the third product rack 313 through the third glue injection pipeline 43, thereby reducing material waste during the injection molding process, helping to reduce production costs, and improving resource utilization efficiency.

[0047] Furthermore, the third glue injection pipeline 43 is connected to the third product rack 313, which can ensure that the injection parameters during the injection molding process are accurately controlled in the third product rack 313, which helps to maintain the consistency and quality of the injection molded products.

[0048] Furthermore, the overall structure of the third product rack 313 is a rectangular parallelepiped, which has good stability and rigidity and can withstand greater pressure and force during the injection molding process, helping to ensure that the injection-molded products in the third product rack 313 can be smoothly molded and ensure the consistency of product size and shape.

[0049] like Figures 1 to 5 The third product rack 313 shown includes a third product mold 3131 and a third glue injection cover 3132. The third product mold 3131 and the third glue injection cover 3132 enclose a third molding cavity 3133. The third glue injection pipeline 43 includes five independent third middle glue injection pipelines 431, a third left glue injection pipeline 432, a third right glue injection pipeline 433, a third auxiliary left glue injection pipeline 434 and a third auxiliary right glue injection pipeline 435. The third glue injection cover 3132 is provided with a third middle glue injection hole 531 connected to and in communication with the third middle glue injection pipeline 431, a third left glue injection hole 532 connected to and in communication with the third left glue injection pipeline 432, a third right glue injection hole 533 connected to and in communication with the third right glue injection pipeline 433, a third auxiliary left glue injection hole 534 connected to and in communication with the third auxiliary left glue injection pipeline 434, and a third auxiliary right glue injection hole 535 connected to and in communication with the third auxiliary right glue injection pipeline 435;

[0050] Optionally, by designing five independent glue injection pipelines 11, namely a third middle glue injection pipeline 431, a third left glue injection pipeline 432, a third right glue injection pipeline 433, a third auxiliary left glue injection pipeline 434 and a third auxiliary right glue injection pipeline 435, glue injection can be performed simultaneously at different positions. Such a setting helps to improve the efficiency of injection molding, shorten the injection molding cycle, and increase production output.

[0051] Furthermore, by setting the injection pipelines 11 and injection holes at different positions, the injection flow can be flexibly arranged and adjusted according to the injection molding requirements and specific shapes of the product. Such a setting can adapt to the injection molding requirements of products of different shapes and meet the injection molding requirements of complex structures.

[0052] like Figures 1 to 5 The first mold 1 shown in the figure is provided with a protective layer 6 on the side close to the second mold 2, and the protective layer 6 is provided with a plurality of accommodating cavities 61 corresponding to each of the product racks 3;

[0053] Furthermore, a receiving cavity 61 is provided on the protective layer 6 to effectively prevent harmful substances such as impurities and corrosive substances from entering the product rack 3 , thereby keeping the surface of the product rack 3 clean and smooth, which is beneficial to extending the service life of the product rack 3 .

[0054] Furthermore, the provision of the protective layer 6, relative to the hollow structure, is conducive to enhancing the overall stability and safety of the device, avoiding mutual interference and collision between the injection pipelines 11 or the product racks 3, reducing accidental losses and mold wear, and facilitating management and operation.

[0055] Further, as a preferred embodiment of the present invention but not limitation, the accommodating chamber 61 includes a first accommodating chamber corresponding to the first product rack 311 , a second accommodating chamber corresponding to the second product rack 312 , and a third accommodating chamber corresponding to the third product rack 313 .

[0056] like Figures 1 to 5 Each of the glue injection pipelines 11 shown is perpendicular to the corresponding product rack 3;

[0057] Furthermore, each glue injection pipeline 11 is perpendicular to the corresponding product rack 3, so that the glue injection material can be injected downward from the top of the glue injection pipeline 11 into the product rack 3. Such an arrangement can achieve a more uniform glue injection distribution, ensuring that each part can be fully injected with glue.

[0058] Furthermore, the design of the glue injection pipeline 11 being perpendicular to the product rack 3 can help reduce the formation of bubbles. The formation of bubbles is usually caused by the inability to discharge air in time during glue injection. By vertically injecting the glue, the glue flows downward along the surface of the product rack, which can effectively discharge air, reduce the formation rate of bubbles, and reduce defects on the product surface.

[0059] Furthermore, the vertical glue injection arrangement makes the glue injection pipeline 11 more concise and compact, convenient for operation and arrangement, and helps to improve production efficiency and reduce cumbersome operation and time waste during the glue injection process.

[0060] like Figures 1 to 5 The volume of each of the molding cavities 33 shown is different;

[0061] Furthermore, by setting up mutually independent molding cavities 33, the volume of each independent molding cavity 33 is different, and the cavity structure of each independent molding cavity 33 is also different. Each independent molding cavity 33 can be used to inject different parts, so that the user can obtain injection molded products of different shapes at the same time in the same injection molding process, which is conducive to improving the use scenarios of injection molds, effectively improving injection molding production efficiency, and saving manpower and time costs.

[0062] The implementation method of this embodiment is as follows:

[0063] A multi-cavity injection mold comprises a first mold 1, a second mold 2 located below the first mold 1 and connected to the first mold 1, the second mold 2 is provided with a first product rack 311, a second product rack 312 and a third product rack 313 which are independent of each other, the first product rack 311 is provided with a first molding cavity 3113, the second product rack 312 is provided with a second molding cavity 3123, the third product rack 313 is provided with a third molding cavity 3133, the first mold 1 is provided with a first glue injection pipeline 41 connected and communicated with the first molding cavity 3113, a second glue injection pipeline 42 connected and communicated with the second molding cavity 3123, and a third glue injection pipeline 43 connected and communicated with the third molding cavity 3133, each glue injection pipeline 11 is independent of each other, which is beneficial for users to inject different injection materials into the independent molding cavities 33 through the glue injection pipelines 11 in the same production batch, so as to obtain injection molded products of different materials in the same production batch, and effectively solves the problem that each molding cavity in the injection mold is connected and communicated so that the injection molded products are all made of the same material. Secondly, the cavity structure of each molding cavity 33 is different, so that the user can obtain injection molded products of different shapes at the same time in the same injection molding process, which is conducive to improving the use scenarios of the injection mold, effectively improving the injection molding production efficiency, and saving manpower and time costs.

[0064] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this.
