Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection mold cavity technology, and in particular to a split injection mold cavity. Background Technology
[0002] The injection mold cavity is the core structure in a mold used to mold plastic products. It is formed by the closing of the moving mold and the fixed mold, creating a molding cavity. It includes a core (punch) and a cavity (cavity), which are responsible for molding the inner and outer surfaces of the product, respectively. The two are precisely aligned during mold closing to form a molding space that conforms to the shape of the product. The core is usually installed on the moving mold, while the cavity is fixed in the fixed mold. Molten plastic is injected through the gating system and then cooled and solidified to form the product.
[0003] Most existing cavities are integrally formed during the manufacturing process, with the forming part machined from a single piece of metal. For cavities with deep grooves, thin ribs, complex curved surfaces, or minute features, machining from a single piece of steel is extremely difficult. Tools may not be able to reach the cavity, or vibration and tool breakage may occur during machining. Furthermore, complex cavities typically require extensive electrical discharge machining (EDM), resulting in a lengthy machining process. Additionally, polishing or texturing specific areas of the cavity, especially narrow or deep areas, is difficult for tools to access, leading to inconsistent machining results and inconsistent surface finish. Therefore, improvements are needed. Utility Model Content
[0004] The main purpose of this invention is to propose a split injection mold cavity, which aims to provide an injection mold cavity that is easy to process.
[0005] To achieve the above objectives, this utility model proposes a split injection mold cavity, including a first injection part and a second injection part, which are separately disposed. The first injection part is provided with a connecting block, and the second injection part is provided with a connecting slot corresponding to the connecting block. The first injection part and the second injection part are assembled and connected by the connecting block and the connecting slot.
[0006] Specifically, the first injection molding part includes an injection molding body and a first connecting end and a second connecting end located at both ends of the injection molding body. An injection space is formed in the middle of the injection molding body. A connecting plate is provided on the first connecting end, and a connecting lock hole is provided on the connecting plate. The first injection molding part is connected to the external fixed mold through the connecting lock hole provided on the connecting plate. The connecting block is provided on the second connecting end.
[0007] Specifically, the second injection molding part includes an injection molding base, which is in the shape of a cover. An assembly block is provided at one end of the injection molding base facing the first injection molding part. An assembly slot that cooperates with the assembly block is provided on the second connecting end. When the second injection molding part is closed with the first injection molding part, the assembly block is located in the assembly slot.
[0008] Specifically, the connecting slot is located on the side of the second injection molding part facing the first injection molding part, and the connecting slot is L-shaped.
[0009] Specifically, the second injection part is provided with an injection groove at the end away from the first injection part, and an injection hole is provided in the injection groove.
[0010] Specifically, the outer side of the injection-molded body is provided with a plurality of annular protrusions, which are spaced apart from each other.
[0011] This utility model's technical solution uses a first injection molding part and a second injection molding part that are formed separately, so that the first injection molding part and the second injection molding part can be processed separately, thereby improving processing efficiency and processing accuracy. At the same time, the first injection molding part and the second injection molding part are connected by connecting blocks and connecting slots, thereby effectively improving assembly efficiency and facilitating daily replacement and maintenance of the injection mold cavity.

[0021] like Figures 1 to 5 As shown, a split injection mold cavity includes a first injection part 10 and a second injection part 20. The first injection part 10 and the second injection part 20 are separately arranged. A connecting block 11 is provided on the first injection part 10, and a connecting groove 21 corresponding to the connecting block 11 is provided on the second injection part 20. The first injection part 10 and the second injection part 20 are assembled and connected by the connecting block 11 and the connecting groove 21. The separate molding of the first injection part 10 and the second injection part 20 facilitates the separate processing of the first injection part 10 and the second injection part 20, thereby improving processing efficiency and accuracy. At the same time, the connection of the first injection part 10 and the second injection part 20 by the connecting block 11 and the connecting groove 21 effectively improves assembly efficiency and facilitates the daily replacement and maintenance of the injection mold cavity.
[0022] The first injection molding part 10 includes an injection molding body 12 and a first connecting end and a second connecting end located at both ends of the injection molding body 12. An injection space is formed in the middle of the injection molding body 12. A connecting plate 13 is provided on the first connecting end, and a connecting locking hole 14 is provided on the connecting plate 13. The first injection molding part 10 is connected to the external fixed mold through the connecting locking hole 14 provided on the connecting plate 13.

An assembly slot 15, which mates with the assembly block 22, is provided on the second connecting end. When the second injection molding part 20 is closed with the first injection molding part 10, the assembly block 22 is located within the assembly slot 15. In this embodiment, by making the injection molding seat cap-shaped, it is easier to mate the injection molding seat with the injection molding body 12 to achieve the closing of the injection molding body 12. Simultaneously, the assembly block 22 on the injection molding seat and the assembly slot 15 on the second connecting end facilitate the use of the assembly block 22 and the assembly slot 15 to improve the stability of the injection molding seat after it is closed with the injection molding body 12.
[0024] The connecting slot 21 is located on the side of the second injection molding part 20 facing the first injection molding part 10, and the connecting slot 21 is L-shaped. In this embodiment, the connecting slot 21 is provided on the side of the connecting slot 21 facing the first injection molding part 10, and the connecting slot 21 is L-shaped, so as to facilitate quick engagement with the connecting block 11 through the connecting slot 21 to realize the mutual locking of the injection molding base and the injection molding body 12.
[0025] An injection groove 23 is provided at the end of the second injection part 20 away from the first injection part 10, and an injection hole 24 is provided in the injection groove 23. In this embodiment, an injection groove 23 is provided on the second injection part 20, and by providing an injection hole 24 in the injection groove 23 and connecting the injection hole 24 to the injection space, the convenience of injection is improved.
[0026] Multiple annular protrusions 16 are formed on the outer side of the injection molding body 12, and the annular protrusions 16 are spaced apart from each other. In this embodiment, multiple spaced annular protrusions 16 are formed on the cut side of the injection molding body 12, which facilitates the operator to grasp the injection molding body 12 and improves the stability of the injection molding body 12 when it moves.
