Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to a multi-cavity mold base. Background Technology

[0002] In the field of injection molds, multi-cavity mold bases are widely used in various injection molding production scenarios because they can produce multiple products at the same time, which can effectively improve production efficiency.

[0003] However, existing multi-cavity mold bases have many drawbacks. On the one hand, some mold bases have relatively simple structures, a limited number of cavities, and poor coordination between cavities, making it difficult to meet the demands of high-efficiency, multi-variety production. On the other hand, injection holes usually lack effective protective devices. During non-production periods, dust and impurities can easily enter the injection holes, contaminating the inner walls and affecting the quality of subsequent injection molded products. This increases the defect rate and makes it difficult to guarantee product molding accuracy, failing to meet the production requirements of high-precision injection molded products. Therefore, we need to upgrade and modify existing technologies. Utility Model Content

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figure 1 As shown in Figure 5, this embodiment provides a multi-cavity mold frame, including a device body 1. The device body 1 contains a mold frame 1 2, a partition plate 3, a mold frame 2 4, a mold frame 3 5, and a base 6. The mold frame 1 2, partition plate 3, mold frame 2 4, and mold frame 3 5 are arranged sequentially from top to bottom on the base 6. The mold frame 1 2 includes a protective plate 21, an upper cavity frame 1 22, a lower cavity frame 1 23, and a positioning rod 24. The upper cavity frame 1 22 is located below the protective plate 21, and the lower cavity frame 1 23 is located below the upper cavity frame 1 22. The positioning rod 24 connects to the upper cavity frame 1 23. The frame 22 and the lower cavity frame 23 are provided with injection hole 7, injection hole 8, injection hole 9 and protective mechanism 10 on the protective plate 21. The protective mechanism 10 includes a strong magnetic ring 101, a fixed shaft 102, a rotating plate 103, a metal cover plate 104, a knob 105 and an anti-slip groove 106. The metal cover plate 104 is rotatably connected to the rotating plate 103 through the fixed shaft 102. The strong magnetic ring 101 is set around the injection hole. The knob 105 is set on the metal cover plate 104. The anti-slip groove 106 is set on the surface of the knob 105.

[0018] Preferably, mold frame 2 4 includes upper cavity frame 2 41, lower cavity frame 2 42 and plug rod 43. Upper cavity frame 2 41 is located below partition plate 3, lower cavity frame 2 42 is located below upper cavity frame 2 41, and plug rod 43 connects upper cavity frame 2 41 and lower cavity frame 2 42, which facilitates the assembly and disassembly of mold frame 2 3, ensures the positioning accuracy between the two, reduces assembly time, improves the assembly efficiency of mold frame, and avoids affecting product molding quality due to structural loosening. Mold frame 3 5 includes support rod 51 and lower cavity frame 3 52. Support rod 51 connects lower cavity frame 2 42 and lower cavity frame 3 52, which can effectively distribute and bear these pressures, prevent the mold frame from deforming due to excessive force, ensure the positional accuracy of lower cavity frame 3 52, and thus ensure the molding accuracy of the product. The base 6 is provided with multiple holes for installation and fixing, which provides convenience for the connection between the mold frame and external equipment (such as injection molding machine worktable). These holes allow for the use of bolts and other connectors to securely fix the mold frame to the worktable, preventing displacement or shaking during operation and ensuring the stability of the injection molding process.

[0019] Preferably, the upper cavity frame 22 and the lower cavity frame 23 are precisely positioned by positioning rods 24. There are at least two positioning rods 24, which can effectively prevent the upper cavity frame 22 and the lower cavity frame 23 from shifting or tilting during assembly, ensuring the relative positional accuracy between the two, reducing the risk of raw material leakage during injection molding, and also ensuring the dimensional and shape accuracy of the product, thus improving the stability of product quality. The upper cavity frame 41 and the lower cavity frame 42 are quickly connected and positioned by insert rods 43. The end of the insert rod 43 is provided with a guide chamfer, which can guide the insert rod 43 to smoothly insert into the corresponding hole, reducing the assembly difficulty, improving the assembly efficiency, avoiding damage to the insert rod 43 or the hole caused by misalignment during assembly, extending the service life of the mold frame, and ensuring the reliability of the connection.

[0020] The working principle and process of this utility model are as follows: During use, the multi-cavity mold frame, through the combination of multiple mold frames (mold frame 1, mold frame 2, and mold frame 3, 5), constructs multiple independent and collaboratively working chamber structures. When injection molding is required, molten injection material is injected into the corresponding chambers through injection holes 1, 8, and 9 on the protective plate. The protective mechanism 10 functions during non-injection periods. The operator can rotate the metal cover plate 104 around the fixed axis 102 using the knob 105 (facilitated by the anti-slip groove 106). The strong magnetic ring 101 adheres to the metal cover plate 104, precisely covering it onto the injection holes to protect them from dust and impurities. Each mold frame layer is precisely positioned and securely connected via positioning rods 24, insertion rods 43, and support rods 51, ensuring the mold frame remains stable during injection molding and thus successfully completing the molding process of the multi-cavity product.
