Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a mold for a Tbox housing. Background Technology

[0002] In related technologies, for the same Tbox product, based on different user needs, some customers require Tbox products with network ports, while others do not, resulting in differences in the casing of the two Tbox products.

[0003] Based on different user needs, the same Tbox product may need to be developed in two different shells, which requires the development and design of two different molds, resulting in high development costs. If two shells are produced using the same mold, a mesh cover plate needs to be added. The mesh cover plate also needs to be produced in a separate mold, which will increase production costs. Furthermore, the mesh cover plate needs to be fixed to the mesh opening of the shell by dispensing glue, which not only makes it difficult to guarantee the sealing performance, but also makes the production process more complicated and increases production costs. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide a mold for a Tbox shell, which can process two types of Tbox shells—one with a mesh opening and one without—by replacing a first insert and a second insert. This eliminates the need for two sets of molds to produce the two types of shells, reducing mold-making costs. Furthermore, the production process eliminates the need for mold development for the mesh opening cover and for adhesive fixing of the mesh opening cover, thereby improving production efficiency and reducing production costs.

[0039] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0043] In this application, "multiple" means two or more (including two).

[0044] The Tbox, short for Telematics Box, is an intelligent in-vehicle terminal device in the vehicle networking system. It is used to realize data interaction and remote control functions between the vehicle and the external network.

[0045] In related technologies, based on the different needs of users, the same Tbox product may need to be equipped with different functions, such as: see Figure 1 and Figure 2 It is configured as a version with an Ethernet interface (i.e., port 110) and a version without port 110.

[0046] Specifically, when a user requires a version with a network port 110, a Tbox housing with a network port 110 is required. When a user does not require a version with a network port 110, a Tbox housing without a network port 110 is required. For Tbox housings without a network port 110, a network port cover 120 is required for sealing purposes, and the network port cover 120 and the Tbox housing need to be further sealed and fixed.

[0047] However, different versions of the Tbox shell require the development and design of two molds for separate processing, resulting in high mold opening costs. Furthermore, the mesh cover plate 120 also requires separate mold production, which further increases the mold opening costs. At the same time, the sealing assembly between the mesh cover plate 120 and the Tbox shell may require glue fixation, which makes the assembly cumbersome and complicated, resulting in low production efficiency and high production costs.

[0048] Based on this, this application proposes a mold for a Tbox shell. By using the same mold and different structural inserts, Tbox shells with mesh openings 110 and Tbox molds without mesh openings 110 can be produced separately. Moreover, there is no need to open a mold for the mesh opening cover 120, which can reduce the number of molds and reduce the mold opening cost. For Tbox shells without mesh openings 110, the mesh opening cover 120 can be produced in an integrated manner without the need for subsequent assembly steps of the mesh opening cover 120. This not only ensures sealing performance but also simplifies the production process, improves production efficiency, and reduces production costs.

[0049] The following is for reference. Figures 1-9 A mold for a Tbox housing according to an embodiment of the present invention is described.

[0050] This application discloses a mold for a Tbox shell, including: a first mold 10, a second mold (not shown in the figure), a first insert 20 and a second insert 30. The first mold 10 and the second mold are joined together, and the Tbox shell is injection molded. The first mold 10 has a mesh opening avoidance portion 121. The first insert 20 and the second insert 30 are detachably disposed on the mesh opening avoidance portion 121. The first insert 20 has a receiving groove 211, which communicates with the mesh opening avoidance portion 121, so as to integrally injection mold the Tbox shell and the mesh opening cover plate 120. The second insert 30 does not have a receiving groove 211, so as to injection mold the Tbox shell with a mesh opening 110.

[0051] Among them, such as Figure 1 and Figure 2 As shown, the Tbox case comes in two versions, namely Figure 1 The version shown is the 110 without a network port. Figure 2 The version shown is 110 with a network port.

[0052] Specifically, after the first mold 10 and then the second mold are closed, an injection cavity is formed between the first mold 10 and the second mold. Injection molding can be performed in the injection cavity to obtain a Tbox shell that conforms to the expected shape. Figure 1 The Tbox shell without mesh opening 110 shown can have a first insert 20 assembled on the first mold 10. The first insert 20 itself has a receiving groove 211 located within the mesh opening avoidance portion 121, so that during injection molding, the injection molding material can flow into the receiving groove 211 to form a mesh opening cover 120, thereby achieving integral injection molding of the mesh opening cover 120 and the Tbox shell. Figure 2 The Tbox housing with mesh opening 110 shown can be fitted with a second insert 30 on the first mold 10. The second insert 30 has no receiving groove 211 so that it fills the mesh opening relief portion 121. When the injection molding material flows into the mesh opening relief portion 121, under the isolation and shaping of the second insert 30, the mesh opening 110 can be formed in the area of ​​the mesh opening relief portion 121 to obtain the Tbox housing with mesh opening 110.

[0053] It is understandable that by combining the first mold 10 and the second mold, and respectively using the first insert 20 to process the Tbox shell without mesh opening 110, and using the second insert 30 to process the Tbox shell with mesh opening 110, the same set of molds can be used to process the injection molding of two versions of the Tbox shell, thus reducing the number of molds. The mesh opening cover 120 can be integrally injection molded with the Tbox shell, eliminating the need for a corresponding cover mold for the mesh opening cover 120, thus reducing the number of molds and lowering the mold opening cost. It also eliminates the assembly steps between the mesh opening cover 120 and the Tbox shell. While improving the sealing performance of the Tbox shell without mesh opening 110, it can also improve production efficiency and reduce production costs.

[0054] According to the mold of the Tbox shell according to the embodiments of this application, the number of molds for processing the Tbox shell can be reduced, thereby reducing the mold opening cost and simplifying the production steps, thereby improving production efficiency and reducing production costs.

[0055] like Figure 3 As shown, according to some embodiments of this application, the first mold 10 includes: a mold body 11, a mesh clearance portion 121 configured as a clearance groove and formed on the mold body 11, and a mounting groove 111 communicating with the clearance groove is also formed on the mold body 11, and the first insert 20 and the second insert 30 are detachably disposed in the mounting groove 111.

[0056] Specifically, the mounting groove 111 is constructed as a through groove and extends through the mold body 11 in the mold closing direction, so that the first insert 20 and the second insert 30 can be assembled to the first mold 10 from one side of the mold body 11 in the mold closing direction, and the other side of the mold body 11 cooperates with the second mold. At least a portion of the first insert 20 or the second insert 30 passes through the mounting groove 111 and can extend into the mesh clearance portion 121 to define the outer contour of the Tbox shell, and then the injection material is injected to obtain the Tbox shell of the desired shape.

[0057] It is understood that the first insert 20 and the second insert 30 are detachably disposed on the first mold 10 through the mounting groove 111. The mounting groove 111 penetrates the mold body 11 in the mold closing direction, so that the assembly direction of the first insert 20 and the second insert 30 is consistent with the mold closing direction and is located on the side away from the second mold in the mold closing direction. This makes the disassembly of the first insert 20 and the second insert 30 easier and reduces the probability of interference with surrounding parts during disassembly, thereby reducing the disassembly difficulty of the first insert 20 and the second insert 30 and improving processing efficiency.

[0058] like Figure 3 As shown, according to some embodiments of this application, the mold body 11 has a first surface a and a second surface b that are opposite to each other in the mold closing direction. A protrusion 12 is formed on the first surface a, the protrusion 12 defines the outer contour of the Tbox shell, and a clearance groove is formed on the protrusion 12.

[0059] In other words, the protrusion 12 defines at least a portion of the outer contour of the Tbox shell, and the mesh clearance portion 121 is formed on one side edge of the protrusion 12 and cooperates with the first insert 20 to define the mesh cover plate 120 located in the mesh clearance portion 121 and located on the peripheral edge of the Tbox shell after molding, or cooperates with the second insert 30 to define the mesh opening 110 located in the mesh clearance portion 121 and located on the peripheral edge of the Tbox shell after molding.

[0060] Therefore, by providing a mesh opening avoidance portion 121 on the protrusion 12, and having the first insert 20 or the second insert 30 extend into the mesh opening avoidance portion 121 and participate in defining the outline of the mesh opening cover 120 or the mesh opening 110 within the mesh opening avoidance portion 121, the mesh opening cover 120 or the mesh opening 110 can be located on the side plate of the Tbox housing, which not only reduces the processing difficulty but also makes the position of the mesh opening 110 more reasonable.

[0061] Combination Figure 4 and Figure 5As shown, according to some embodiments of this application, the mounting groove 111 includes: a first groove segment 1111 and a second groove segment 1112, the second groove segment 1112 communicating with the clearance groove, and the outline dimension of the first groove segment 1111 being larger than the outline dimension of the second groove segment 1112, so as to define at least one stepped surface, the stepped surface being disposed adjacent to the second surface b, and used to push and limit the first insert 20 or the second insert 30.

[0062] Specifically, in the direction towards the second mold, the first groove segment 1111 and the second groove segment 1112 are arranged sequentially so that the end face of the second groove segment 1112 defines a stepped surface on the side facing the first groove segment 1111. Thus, during the process of inserting the first insert 20 or the second insert 30 into the mounting groove 111, the end of the first insert 20 or the second insert 30 away from the second mold can at least partially push against the stepped surface to limit the first insert 20 or the second insert 30. This makes the size of the part of the first insert 20 or the second insert 30 that extends out of the protrusion and into the mesh clearance part 121 more reasonable, avoiding excessively long or short protrusions, thereby improving processing accuracy and processing quality.

[0063] like Figure 5 As shown, according to some embodiments of this application, when projecting an orthographic projection from the second surface b toward the first surface a, the orthographic projection profile size of the first groove segment 1111 is larger than the orthographic projection profiles of the first insert 20 and the second insert 30.

[0064] In other words, the contour dimension of the first groove segment 1111 in the mold closing direction is larger than that of the first insert 20 and the second insert 30, so that there is a gap between the first insert 20 and the inner wall of the first groove segment 1111, and between the second insert 30 and the inner wall of the second groove segment 1112, so as to facilitate the demolding of the first insert 20 and the second insert 30, making the disassembly of the first insert 20 and the second insert 30 easier. Of course, after the first insert 20 and the second insert 30 are demolded, the ejector pin can also be inserted through the mounting groove 111, which facilitates the demolding of the Tbox shell and improves processing efficiency.

[0065] Combination Figure 6 and Figure 7 As shown, according to some embodiments of this application, the first insert 20 includes: a first protruding section 21 and a first embedded section 22. The first embedded section 22 is embedded into the mounting groove 111, the first protruding section 21 extends out of the mounting groove 111 and is located in the relief groove, and the receiving groove 211 is formed in the first protruding section 21 and participates in defining the mesh cover plate 120. The first insert 20 also includes: a first limiting section 23. The first limiting section 23 is located at the end of the first embedded section 22 away from the first protruding section 21, and the first limiting section 23 pushes against the mold body 11.

[0066] Combination Figure 8 and Figure 9As shown, according to some embodiments of this application, the second insert 30 includes: a second protruding section 31 and a second embedded section 32. The second embedded section 32 is embedded into the mounting groove 111, and the second protruding section 31 extends out of the mounting groove 111 and is located in the clearance groove to participate in defining the mesh opening 110. The second insert 30 also includes: a second limiting section 33. The second limiting section 33 is located at the end of the second embedded section 32 away from the second protruding section 31, and the second limiting section 33 pushes against the mold body 11.

[0067] The first limiting segment 23 allows the relative position of the first insert 20 and the first mold 10 to be fixed after the first insert 20 is inserted into the mounting groove 111. The first embedding segment 22 can be used to define the outline of the mesh cover plate 120 so as to facilitate the integral injection molding of the mesh cover plate 120 and the Tbox shell. The second limiting segment 33 allows the relative position of the second insert 30 and the first mold 10 to be fixed after the second insert 30 is inserted into the mounting groove 111. The second embedding segment 32 can be used to define the outline of the mesh 110 so as to facilitate the injection molding of the Tbox shell with the mesh 110.

[0068] This not only improves the processing efficiency and quality of the two types of Tbox shells, but also reduces the number of molds, thereby lowering production costs.

[0069] It should be noted that the mold closing direction in this embodiment is the up-down direction.

[0070] Other configurations and operations of the mold for the Tbox housing according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
