Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold that is easy to adapt to the molding cavity. Background Technology

[0002] In the molding process of injection molding, the number of molding cavities directly affects the efficiency of a single molding. Multi-cavity molds can produce multiple products at once, greatly improving production efficiency. However, molds with different numbers of cavities face many challenges in the adaptation process. Due to limitations such as mold structure and injection molding machine parameters, molds with different numbers of cavities have compatibility issues in terms of installation, debugging, and production process control, making it difficult to achieve flexible switching and efficient production.

[0003] Taking existing injection molds as an example, an injection mold with application number CN202421642239.4, although it has a unique material cutting function and some innovations in nozzle movement and excess material handling, adopts a single-cavity structure and does not have a detachable molding cavity. This means that the mold can only mold one product at a time in actual use, resulting in low production efficiency. At the same time, due to the lack of a cavity replacement mechanism, it cannot meet the production needs of diversified products and has serious incompatibility when facing production tasks of different specifications and quantities of products.

[0004] Based on this, this proposal puts forward a technical solution of "an injection mold that is easy to adapt to the molding cavity". Utility Model Content

[0005] The purpose of this invention is to provide an injection mold that is easy to adapt to the molding cavity, so as to solve the problem mentioned in the background art that the existing equipment on the market cannot meet the production needs of diversified products and has serious incompatibility when facing production tasks of products with different specifications and quantities.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an injection mold that is easy to adapt to the molding cavity, comprising an upper module, a lifting ring, a connecting plate, a bottom module, and a film placement groove;

[0007] A molding cavity structure is provided above the upper module. The molding cavity structure includes a connecting plate, a first molding cavity block, a second molding cavity block, a molding groove, a shaping film block, and a film placement groove. The film placement groove is located above the connecting plate. The shaping film block is installed in the film placement groove, and the first molding cavity block and the second molding cavity block are fitted on top of the shaping film block. A molding groove is provided on the inner side of the first molding cavity block and the second molding cavity block.

[0008] As a preferred technical solution of this utility model, a pair of lifting rings are threaded to the top of the upper module, an equilateral trapezoidal groove is opened at the bottom of the upper module, and the upper module as a whole is a T-shaped structure. A pair of through holes are opened on the side of the upper module to assist docking and movement.

[0009] By adopting the above technical solution, the lifting ring at the top of the upper module facilitates the movement and handling of the mold with the help of hoisting equipment, reducing the difficulty of manual handling and improving the convenience of mold installation and debugging; the equilateral trapezoidal groove and T-shaped integral structure at the bottom of the upper module can form a stable fitting relationship with the lower components, enhancing the structural stability of the mold when it is closed; the through hole on the side can assist the mold in precise docking with other equipment, while providing additional force points for mold movement, improving operational flexibility.

[0010] As a preferred technical solution of this utility model, a second guide rod is slidably connected below the upper module. The top of the second guide rod has a conical structure, and the bottom of the second guide rod is fixedly connected to the connecting plate. A first guide rod is fixedly connected to the upper surface of the connecting plate. The first guide rod and the second guide rod are distributed adjacent to each other, and the diameter of the second guide rod is 1.5 times that of the first guide rod. The upper module is slidably connected above the first guide rod.

[0011] Using the above technical solution, the tapered structure at the top of the second guide rod can play a guiding role during the mold closing process, facilitating quick alignment between the upper module and the connecting plate and reducing docking time. Its sliding connection with the upper module ensures the smoothness of the mold closing process. The adjacent distribution and diameter difference design of the first and second guide rods form a dual guide structure. The second guide rod with a larger diameter undertakes the main guiding and load-bearing functions, while the first guide rod with a smaller diameter assists in positioning. The combination of the two greatly improves the mold closing accuracy and reduces product defects caused by positioning deviations.

[0012] As a preferred technical solution of this utility model, the guide plate is fixed by bolts on the side of the upper module. The guide plates are symmetrically distributed in groups of two, and the guide plates are generally right-angled trapezoidal structures. Guide grooves are opened on the surface of the guide plates, and the guide grooves are inclined structures.

[0013] Using the above technical solution, two symmetrically distributed right-angled trapezoidal guide plates provide a stable installation and sliding foundation for the first molding cavity block and the second molding cavity block, ensuring the symmetry and consistency of their movement; the inclined guide groove can guide the first molding cavity block and the second molding cavity block to achieve precise opening and closing actions during the sliding process, making the position adjustment of the molding cavity block more stable, facilitating the quick adaptation of the molding groove and the molding film block, and meeting the injection molding requirements of products of different sizes.

[0014] As a preferred technical solution of this utility model, the first molding cavity block and the second molding cavity block are slidably connected in the guide groove of the guide plate. The first molding cavity block and the second molding cavity block have the same structure, and the upper part of the first molding cavity block and the second molding cavity block fits with the groove of the upper module. A molding groove is opened on the inner side of the first molding cavity block and the second molding cavity block.

[0015] By adopting the above technical solution, the first molding cavity block and the second molding cavity block are slidably connected in the guide groove, which realizes the flexible adjustment of their positions. The size of the molding cavity can be changed according to the product specifications, which enhances the versatility of the mold. The fit design between the two and the upper module groove enhances the stability of the molding cavity block during the working process and reduces the positional displacement caused by vibration during injection molding. The inner molding groove directly constitutes the molding space of the injection molded product, ensuring the basic shape accuracy of the product.

[0016] As a preferred technical solution of this utility model, the first molding cavity block and the second molding cavity block are fitted on top of the shaping film block, and a total of seven injection heads on the shaping film block are matched with the molding groove. A film groove is opened on the upper surface of the connecting plate, and the shaping film block is fixed to the connecting plate by the film groove and bolts.

[0017] Using the above technical solution, the shaping film block is fitted under the first molding cavity block and the second molding cavity block and fixed by the film placement groove, which facilitates the quick replacement of the shaping film block according to different product shapes, reducing the cost and time of mold adaptation to different products; the matching design of the seven injection heads on the top of the shaping film block with the molding groove ensures that the injection molding material is evenly filled into the molding groove, improving the injection molding quality and consistency of the product; the film placement groove on the connecting plate provides precise installation positioning for the shaping film block, ensuring the relative positional accuracy of the shaping film block and the molding cavity block.

[0018] As a preferred technical solution of this utility model, the bottom of the connecting plate is symmetrically fixed with a total of six positioning blocks. The positioning blocks have circular holes on their sides. The connecting plate is slidably connected to the bottom module through the positioning blocks and positioning grooves. The long screw on the side of the bottom module passes through the connecting plate to fix the connecting plate and the bottom module.

[0019] By adopting the above technical solution, the positioning block at the bottom of the connecting plate is slidably connected to the positioning groove of the bottom module, realizing the rapid positioning of the connecting plate and the bottom module, ensuring the alignment accuracy of the overall mold structure, and reducing the deviation during mold closing; the design of the long screw penetrating the connecting plate and fixing the bottom module can firmly connect the connecting plate and the bottom module, enhance the overall stability of the mold during operation, avoid the loosening of parts due to vibration during injection molding, and improve the molding accuracy of the product.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. The lifting ring on the top of the upper module facilitates mold handling, while the T-shaped structure and equilateral trapezoidal groove enhance mold closing stability. Side holes assist in docking and movement. The positioning groove of the bottom module cooperates with the positioning block of the connecting plate to achieve quick positioning, and the long screw ensures a firm connection. Overall, it improves the convenience and stability of mold installation and fixing, and reduces mold closing deviation.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figure 1 - Figure 8 The present invention provides a solution for an injection mold that is easy to adapt to the molding cavity, comprising an upper module 1, a lifting ring 2, a connecting plate 3, a bottom module 4, a long screw 5, a guide plate 6, a guide groove 7, a first molding cavity block 8, a second molding cavity block 9, a first guide rod 10, a second guide rod 11, a positioning block 12, a positioning groove 13, a molding groove 14, a shaping film block 15, and a film placement groove 16.

[0036] The top of the upper module 1 is threaded with a pair of lifting rings 2. An equilateral trapezoidal groove is opened at the bottom of the upper module 1, and the whole is in the shape of a T-shape. A pair of through holes are provided on the side to assist docking and movement.

[0037] The lifting ring 2 facilitates the movement and handling of the mold, and the position can be easily adjusted with the help of lifting equipment, reducing the difficulty of manual operation; the T-shaped structure and equilateral trapezoidal groove can make the upper module 1 and the lower part fit together firmly, improving the overall stability when the mold is closed; the through hole can help the mold to accurately dock with other equipment, and can also provide additional force points when moving, making the operation more convenient;

[0038] The upper module 1 is slidably connected to the lower part of the second guide rod 11. The top of the second guide rod 11 is tapered and the bottom is fixed to the connecting plate 3. The upper surface of the connecting plate 3 is provided with the first guide rod 10. The two guide rods are distributed adjacent to each other. The diameter of the second guide rod 11 is 1.5 times that of the first guide rod 10. The upper part of the first guide rod 10 is slidably connected to the upper module 1.

[0039] The tapered top of the second guide rod 11 can guide the mold during closing, helping the upper module 1 and the connecting plate 3 to quickly align and making the mold closing process smoother. The design of the double guide rods creates a double guiding effect. The larger diameter second guide rod 11 is mainly responsible for guiding and bearing the load, while the first guide rod 10 assists in positioning, improving the accuracy of mold closing and reducing product defects caused by positioning problems.

[0040] A pair of symmetrical right-angled trapezoidal guide plates 6 are fixed to the side of the upper module 1 by bolts. An inclined guide groove 7 is provided on the surface. The first forming cavity block 8 and the second forming cavity block 9 with the same structure are slidably connected in the guide groove 7. The upper part of the two forming cavity blocks fits into the groove of the upper module 1, and the inner side is provided with a forming groove 14.

[0041] The symmetrical guide plate 6 provides stable sliding support for the molding cavity block, and the inclined guide groove 7 can guide the two molding cavity blocks to slide smoothly, realizing flexible position adjustment to meet the needs of different specifications of products; the fit between the molding cavity block and the groove of the upper module 1 enhances the stability during operation and reduces the positional displacement caused by vibration, while the molding groove 14 directly determines the basic shape of the injection molded product.

[0042] The first molding cavity block 8 and the second molding cavity block 9 are fitted on top of the shaping film block 15. The shaping film block 15 is fixed to the connecting plate 3 by bolts through the film placement groove 16. The top is provided with seven injection heads that match the molding groove 14. The six positioning blocks 12 at the bottom of the connecting plate 3 are slidably connected to the bottom module 4 through the positioning groove 13. The long screw 5 on the side of the bottom module 4 passes through the connecting plate 3 to achieve fixation.

[0043] The molding block 15 is fixed by the molding groove 16, which facilitates quick replacement according to different products, reducing adaptation costs and time; the matching of the injection head and the molding groove 14 can make the raw material fill evenly and ensure product quality; the cooperation between the positioning block 12 and the positioning groove 13 realizes the quick positioning of the connecting plate 3 and the bottom module 4, while the long screw 5 ensures the firmness of the connection, improves the overall stability of the mold during operation, reduces the loosening of parts caused by vibration, and ensures the molding accuracy of the product.

[0044] Working principle: When using an injection mold that is easy to fit the molding cavity, first select the corresponding molding block 15 according to the specifications and shape of the product to be injected, and fix it in the mold placement groove 16 above the connecting plate 3 with bolts to ensure that the molding block 15 is installed firmly.

[0045] Subsequently, the first molding cavity block 8 and the second molding cavity block 9 are pushed to slide along the inclined guide groove 7 on the guide plate 6 until the molding groove 14 on the inner side of the two molding cavity blocks is precisely attached to the top of the shaping film block 15. At the same time, the top of the first molding cavity block 8 and the second molding cavity block 9 are tightly fitted with the equilateral trapezoidal groove below the upper module 1, thus completing the assembly and adaptation of the molding cavity.

[0046] Using the lifting ring 2 at the top of the upper module 1, the upper module 1 is lifted by the hoisting equipment and moved above the bottom module 4. At this time, the positioning block 12 at the bottom of the connecting plate 3 corresponds to the positioning groove 13 on the bottom module 4. The positioning block 12 slides along the positioning groove 13 to achieve initial positioning. At the same time, the conical structure at the top of the second guide rod 11 guides the upper module 1 to align with the connecting plate 3. The first guide rod 10 and the second guide rod 11 cooperate to achieve precise guidance, so that the upper module 1 and the lower component can be smoothly molded together.

[0047] After the mold is closed, the long screw 5 on the side of the bottom module 4 is used to pass through the connecting plate 3 and tighten it to firmly fix the connecting plate 3 and the bottom module 4, so as to avoid loosening during the injection molding process. During injection molding, the raw material is injected through the injection head above the shaping film block 15, and is formed by the cavity formed by the molding groove 14 and the shaping film block 15, and finally the product injection molding is completed.

[0048] When it is necessary to change the product specifications, loosen the long screw 5, remove the upper module 1 through the lifting ring 2, slide the first forming cavity block 8 and the second forming cavity block 9 to separate them from the shaping film block 15, replace the corresponding shaping film block 15 and repeat the above steps to achieve rapid adaptation and production of different products.

[0049] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
