[0043] refer to Figure 6-7In this embodiment, the movable mold insert 230 is also provided with a sub-insert setting groove 231 and a plurality of sub-inserts 232 corresponding to products of different models. The sub-insert 232 is detachably arranged in the sub-insert setting groove 231. The plurality of sub-inserts 232 corresponding to products of different models have the same basic structural features. The plurality of sub-inserts 232 corresponding to products of different models have different independent structural features. The sub-inserts 232 on the sub-insert setting groove 231 are replaced to produce products of corresponding models.

[0044] In this embodiment, if Figure 8-11 As shown, the movable mold insert 230 includes a plurality of sub-insert setting grooves 231 of the same size. By setting a plurality of sub-insert setting grooves 231, a plurality of sub-inserts 232 can be set. The sub-inserts 232 can be of the same model or of different models, thereby forming a plurality of products or products of multiple models at one time.

[0045] In this embodiment, the same basic structural features include corner structural features, wherein the corner structural features include corner shape, corner height and corner position.

[0046] In this embodiment, the buckle angle structural feature is embodied in the buckle angle insert 234, and the buckle angle insert 234 is provided with corresponding structural features to form the buckle angle structure during molding. Specifically, a plurality of buckle angle setting grooves 233 are provided at the same position of the edge of the sub-insertion 232, and the buckle angle structural feature is provided on the buckle angle insert 234, and the buckle angle insert 234 is embedded in the buckle angle setting groove 233 to form the buckle angle structural feature of the sub-insertion 232. In this embodiment, the buckle angle inserts 234 of each sub-insertion 232 all adopt the same structure, are provided at the same position of the sub-insertion 232, and the shape, size and depth and other parameters of the buckle angle setting groove 233 are also the same. After molding, the same products or products of different models all have the same buckle angle structure. The same or different models of sub-insertions all use the same buckle angle insert 234, and the design of a new sub-insertion 232 does not need to consider the buckle angle structure, and the buckle angle insert 234 is also easy to replace if it is broken.

[0047] In this embodiment, combined with Fig.11 As shown, the bottom surface of the angle setting groove 233 is an inclined surface, the angle setting groove 233 extends from the top to the bottom of the sub-inserted block 232, the angle setting block 234 is provided with an extension portion 2341 extending toward the bottom of the sub-inserted block 232, and the movable template 210 is provided with a through avoidance hole 212 (reference Figure 7As shown in the figure), the extension part 2341 passes through the avoidance hole 212 and is connected with the lifting mechanism of the movable mold assembly 200. A positioning groove 2342 is provided at the end of the extension part 2341. The lifting mechanism of the movable mold assembly 200 is provided with a positioning structure (not shown in the figure) for fixing the positioning groove 2342. The positioning structure is used to anchor the positioning groove 2342, thereby limiting the position of the buckle angle insert 234 together with the buckle angle setting groove 233.

[0048] In this embodiment, the angle setting groove 233 extends from the top to the bottom of the sub-insert block 232, and the extension part 2341 extends to the bottom, so that it can be connected to the lifting mechanism of the movable mold assembly 200 in a transmission manner. The angle insert block 234 and the extension part 2341 together constitute an ejector pin (oblique ejector) for ejecting the product, and the angle setting groove 233 constitutes an ejector pin hole (ejector pin hole of the sub-insert block 232), and the avoidance hole 212 constitutes an ejector pin hole of the movable mold plate. The lifting mechanism can drive the extension part 2341 and the angle insert block 234 to move, which is used to eject the injection molded product, and is also an oblique ejector for easy demoulding. Of course, as other embodiments, in addition to the ejector pin formed by the angle insert block, other ejectors can also be provided; or, only other ejectors are provided, and the angle insert block is not used as an ejector pin.

[0049] In this embodiment, the extension 2341 is connected to the bottom of the corner insert 234, and a first positioning surface 2343 is reserved at the bottom of the corner insert 234. The sub-insert setting groove 231 is provided with a convex portion 2311 protruding from the groove arm, and the convex portion 2311 is provided with a second positioning surface 2313 that matches the first positioning surface 2343. The convex portion 2311 is embedded in the corner setting groove 233 so that the first positioning surface 2343 is matched with the second positioning surface 2313. The convex portion 2311 is further positioned to make the position of the corner insert 234 more accurate.

[0050] In this embodiment, the same basic structural features include ejection structural features, wherein the ejection structural features include: ejection position, ejection hole shape, and ejection hole size. Figure 8 As shown, the ejection holes (i.e., the sub-block setting grooves 231) are evenly distributed on the edges of the sub-blocks 232. Only one type of ejection hole of the sub-block is shown in the figure, and the positions and sizes of the ejection holes of other types of sub-blocks are the same, so that any sub-block can be set in any sub-block setting groove to achieve the ejection operation. Correspondingly, the ejector length (and extension length), shape, and structure of the ejector mechanism of the movable mold assembly 200 are also the same, so as to facilitate the versatility of the mold frame.

[0051] In this embodiment, the same basic structural features include gate structural features, wherein the gate structural features include: gate position, gate size, and the shape of the bull horn gate. Figure 8-12 As shown, a runner 2301 is provided on the movable mold insert 230, and the runner 2301 is divided into a plurality of sub-runners corresponding to each sub-insert to set a groove 231, and a gate installation position 2321 is provided at the same position of each sub-insert 232, and a gate insert 235 forming a bull horn gate 2350 is arranged at the gate installation position 2321, and the sub-runner is connected with the bull horn gate 2350 of the corresponding gate insert 235. Sub-inserts of the same or different models all use the same gate installation position 2321, and the same gate insert 235, and thus the structure of the bull horn gate 2350 is also the same, which is convenient for matching with the sub-runner.

[0052] In this embodiment, the same basic structural features include the jack structural features, wherein the jack structural features include: the jack size and the jack depth. In particular, for the corresponding socket panel, the jack structural features are important structural features, such as Figure 8 As shown, this can be achieved by a jack insert 239 with the same structural shape and depth. The sub-insert 232 is provided with a jack insert groove, and the jack insert 239 is embedded in the jack insert groove to form a jack structure.

[0053] In addition, if Figure 8 and Fig.13 As shown, in some products, a notch structure is also provided, which is formed by providing a notch insert 236. The notch insert 236 is also universal for multiple models, and the sub-insert 232 is provided with a notch groove 233, and the notch insert 236 is embedded in the notch groove 233 to form the notch structure.

[0054] This embodiment, through the design of the water channel (gate), ejection mechanism and basic structural features, makes the mold of the plastic shell product of this embodiment applicable to the molding of multiple products. The sub-inserts can be installed in any sub-insert setting groove 231 due to the same basic structural features, so that one mold can be used to mold multiple products. The same basic structural features can also be designed into an independent insert structure, so as to meet the universal requirements of multiple models of products and reduce the design and development process of subsequent new products.

[0055] Correspondingly, the design of subsequent related products and mold design are all designed based on sub-inserts with the same basic structural characteristics. Universal dynamic mold inserts, universal dynamic mold plates, and universal static mold groups can be used, making the entire mold universal for subsequent products.

[0056] For this embodiment, different models of products have different independent structural features, specifically, Fig.14As shown in the figure, four different models of products and the corresponding sub-block structures are given. The independent structural features of different products include: number of jacks, 3-pin or 2-pin, button hole, serial number text content, certification mark, product appearance curvature, etc.

[0057] like Fig.15 As shown, one mold platform can realize the molding of various types of products, and different sub-inserts can be interchanged to mold different products.

[0058] Based on the above, this embodiment can provide a method for designing a mold for a plastic shell product, including the steps of:

[0059] S1, extract basic data from the data information of various plastic shell products.

[0060] In this embodiment, the integrated data of the plastic shell product mainly includes some common data, such as size, buckle, stud, rib and other data. Taking the panel of a wall switch or socket as an example, the shape of the wall switch is basically rectangular or square, so the panel is also rectangular or square, and its size is basically evaluated by length, width and height. The length, width and height of various panels have certain differences, but the shape is basically the same, so they have commonality. The buckle is an important structure for connecting the panel to the middle frame or base. Basically, the panel has a buckle, and the stud is also the same. The rib is to improve the structural strength of the panel. Most panels are designed with a rib structure. These data are the basis for most panels when designing. The difference is that when new structures derived from new needs, such as USB ports, clock displays and other new functions are introduced, corresponding structural support needs to be added to the panel. However, these functions are not the functions of a commonly used socket or switch, so these features belong to independent structural features.

[0061] In this embodiment, the basic data includes: the position and size of the gate, the shape of the bull horn gate, the length, size and position of the ejector pin of the ejector system, the position and size of the ejector pin hole and the inclined ejector hole, the maximum shape of the sub-insert, the size and depth of the socket, the size and position of the insert hanger, the depth, size, quantity and position of the insert exhaust, etc.

[0062] In this embodiment, the independent structural features of different products include: the number of jacks, whether it is 3-jack or 2-jack, button hole, serial number text content, certification mark, product appearance curvature, etc.

[0063] S2, standardizing the basic data of the various plastic shell products to make the basic data of the various plastic shell products consistent.

[0064] In this embodiment, the purpose of extracting basic data is to make the basic data consistent. Since there are many types of product buckle angles and no standardization has been formed, the mold design needs to be designed for different shapes and sizes each time, which fails to effectively improve the design efficiency. For mold processing, for workpieces with different structures and sizes, each processing requires re-directing, programming, and processing, resulting in waste of production costs. If the same type of product design has the same buckle angle shape and size, the design can be directly imported into the template, which effectively improves the design efficiency and the first-time design pass rate. Batch production can be carried out during processing, and universal spare parts can be made. If the accessory is damaged during the mold production process, it can be replaced immediately, shortening the maintenance cycle and not affecting production.

[0065] S3, designing the ejector pin hole of the mold frame based on the standardized basic data.

[0066] like Figure 4 The following are the mold frame structures of two products. Since the two products belong to different mold frame platforms, the ejector hole designs on the mold frames are different. Therefore, the standardized ejector hole design can be applied to a variety of products.

[0067] S4, designing the appearance of the sub-assembly 232 based on the standardized basic data.

[0068] Please continue to refer to Figure 4 Since the mold frame platforms of the two products are different, the appearance of the sub-insert 232 and the installation structure of the mold frame to the sub-insert 232 are also different. After standardization, one mold frame platform can be suitable for the sub-insert 232 of multiple products.

[0069] S5, designing the size and basic structural features of the sub-insert 232 based on the standardized basic data to obtain a standardized insert basic model.

[0070] The existing mold base platform can only be used for inserts of the same product, and cannot be used for inserts of other products, mainly because the designs of various products are different, and the mold base platform, inserts, etc. are all different. Through the standardized basic data, the sub-insert 232 can be standardized to obtain a standardized insert basic model.

[0071] S6, based on the standardized insert basic model, the independent structure design of the sub-insert 232 is performed separately based on the plastic shell products with different independent structural characteristics.

[0072] Different plastic shell products have different independent structural characteristics. Based on the standardized insert basic model, the mold design process of the product can be accelerated.

[0073] S7, designing the water channels of the mold frame, the sub-insert block 232 and the movable mold insert block 230 based on the standardized basic data.

[0074] The existing mold frame platform, mold ejector holes, water channel sizes, and water channel designs are varied, which affects the design efficiency and processing efficiency. In addition, the mold frame layout is also different, and the mold frame cannot be reused. By standardizing the design of the shape and other dimensions of the inserts of similar products, the inserts of similar products can be switched on the same mold frame. This not only reduces the cost of the mold frame, but also allows multiple products to be produced on one machine at the same time, saving the time of changing lines and materials.

[0075] In this embodiment, the method further comprises the steps of:

[0076] S8, based on the standardized basic data, establish a basic product model and archive it as the data basis for subsequent new product development.

[0077] Preferably, the method further comprises the steps of:

[0078] S9, archiving the standardized insert basic model as the sub-insert 232 data basis for subsequent new product development.

[0079] Preferably, in step S1, the process of extracting basic data from the data information of a variety of plastic shell products includes:

[0080] S1a, obtain the basic dimensions and basic features of various plastic shell products;

[0081] In step S2, the process of standardizing the basic data of the various plastic shell products to make the basic data of the various plastic shell products consistent includes:

[0082] S2a, designing the basic dimensions of various plastic shell products to be the same, and designing the basic features of various plastic shell products to be the same.

[0083] Preferably, in step S5, the process of designing the basic structural features of the sub-assembly 232 based on the standardized basic data includes:

[0084] Design standardized buckle shape, buckle height, buckle position and bevel height.

[0085] Preferably, in step S3 , the movable mold insert 230 is designed with a plurality of sub-insert setting grooves 231 for embedding a plurality of sub-inserts 232 .

[0086] Preferably, the plurality of sub-inserts 232 are sub-inserts 232 of the same type of products or sub-inserts 232 of different types of products.

[0087] Preferably, the method further comprises the steps of:

[0088] S10, archiving the sub-module 232 designed based on the standardized basic data as a standardized sub-module 232 basic model.

[0089] Preferably, in step S1, the plurality of plastic shell products are products of the same type or products of different types.
