DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0039] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0040] The integrated interface insert structure, injection mold and housing provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in combination with the accompanying drawings.

[0041] like Figure 1 , Figure 2 As shown, the embodiment of the present application provides an integrated interface insert structure, including a plurality of insert bodies 110 arranged in parallel, and a first transition piece 120 and a second transition piece 130 are fixedly provided on the plurality of insert bodies 110 .

[0042] The first transition piece 120 and the second transition piece 130 are injection molded on a plurality of insert bodies 110 and are arranged at intervals along the extension direction of the insert bodies 110. The second transition piece 130 is respectively fixed with reinforcement units on both side end faces in the reference axial direction. The reinforcement units include a support column 140 fixedly connected to the second transition piece 130 and a plurality of sealing rings 150 coaxial with the support column 140.

[0043] The reference axial direction is specifically a direction perpendicular to the plane where the multiple insert bodies 110 are located, and the multiple sealing rings 150 increase in radial diameter along the support column 140 .

[0044] In an embodiment of the present application, an integrated interface insert structure as described above is adopted, and the relative positions of multiple insert bodies 110 are fixed by means of a first transition piece 120 and a second transition piece 130, that is, multiple insert bodies 110 are connected into a whole, thereby improving the structural strength of the insert body 110 and avoiding structural deformation in subsequent injection molding. At the same time, a reinforcement unit is arranged on the second transition piece 130. When the insert body 110 is further injection molded, the contact area between the second transition piece 130 and the colloid can be increased by the cooperation of the support column 140 and the sealing ring 150, thereby ensuring the connection reliability between the injection molded component and the insert structure, improving the sealing between the injection molded component and the second transition piece 130, reducing the bubbles generated in the colloid, and further improving the product quality.

[0045] In a preferred embodiment, Figure 1 , Figure 2 As shown, at least one reinforcement unit is provided on both side end surfaces of the second transition piece 130 .

[0046] In a preferred embodiment, Figure 1 , Figure 2 As shown, the support column 140 is specifically configured to be in a truncated cone shape, and the end with a smaller diameter is located at a side away from the second transition piece 130 .

[0047] In a preferred embodiment, Figure 1 , Figure 2 As shown, a positioning hole 111 is formed through the insert body 110 and is located between the first transition piece 120 and the support column 140 .

[0048] In a preferred embodiment, Figure 1 , Figure 2 As shown, a connecting piece 160 located between the first transition piece 120 and the second transition piece 130 is fixedly disposed between two adjacent insert bodies 110 .

[0049] It can be understood that the connecting piece 160 can connect two insert bodies 110 at corresponding positions, and a plurality of insert bodies 110 and the connecting pieces 160 at corresponding positions can be configured to be integrally stamped.

[0050] like Figures 3 to 8 As shown, an embodiment of the present application provides an injection mold for injection molding of the above-mentioned integrated interface insert structure, including a lower mold 210, an upper mold 220 that can be pressed together with the lower mold 210, and an injection unit 300 arranged on the upper mold 220.

[0051] The end face of the lower mold 210 close to the upper mold 220 is provided with a positioning groove 211 that can be embedded and positioned with multiple insert bodies 110, a first cavity 212 matching the shape of the first transition piece 120, and a second cavity 213 matching the shape of the second transition piece 130. The positioning groove 211 is fixedly provided with a positioning protrusion 214 that can be plugged into the positioning hole 111 on the inner wall on the side away from the upper mold 220, and the second cavity 213 is provided with a first supporting groove 215 matching the shape of the reinforcement unit on the inner wall on the side away from the upper mold 220.

[0052] The upper mold 220 has a third cavity 221 on its end face close to the lower mold 210 that matches the shape of the first transition piece 120, a fourth cavity 222 that matches the shape of the second transition piece 130, and an embedding hole 225 that can be plugged into the positioning protrusion 214. The fourth cavity 222 has a second supporting groove 224 on its inner wall that matches the shape of the reinforcement unit on the side away from the lower mold 210.

[0053] Among them, when the lower mold 210 and the upper mold 220 are pressed together, the first cavity 212 and the third cavity 221 are buckled together to form a sealed first injection cavity, and the second cavity 213 and the fourth cavity 222 are buckled together to form a sealed second injection cavity. The injection unit 300 can inject glue into the first injection cavity and the second injection cavity to form the first transition piece 120 and the second transition piece 130.

[0054] When performing injection molding, the insert body 110 is first placed in the positioning groove 211, and the positioning protrusion 214 is plugged into the positioning hole 111. When the insert body 110 is positioned, the upper mold 220 moves to the side close to the lower mold 210 until it is pressed together. The first cavity 212 and the third cavity 221 are buckled together to form a sealed first injection cavity, and the second cavity 213 and the fourth cavity 222 are buckled together to form a sealed second injection cavity. The positioning protrusion 214 is plugged into the embedding hole 225. When the lower mold 210 and the upper mold 220 are completely pressed together, the injection unit 300 is started and glue is injected into the first injection cavity and the second injection cavity, thereby realizing the injection molding of the first transition piece 120 and the second transition piece 130 on multiple insert bodies 110, and realizing the integral injection molding of the reinforcement unit and the second transition piece 130 through the first support groove 215 and the second support groove 224.

[0055] In a preferred embodiment, Figure 4 , Figure 5 , Figure 7 , Figure 8 As shown, the injection unit 300 includes an injection device fixedly connected to the upper mold 220, and a glue separator 320 connected to the injection device and capable of injecting glue into the first injection cavity and the second injection cavity.

[0056] A clearance groove 310 capable of being embedded with the glue separating piece 320 is provided on the end surface of the lower mold 210 close to the upper mold 220 .

[0057] It is understandable that the setting form of the injection unit 300 is not limited to the above-mentioned one. For example, the injection molding device and the glue dividing part 320 can be set on the lower mold 210. At this time, the outflow direction of the colloid will change, but the glue can also be injected into the first injection cavity and the second injection cavity, which will not be elaborated here.

[0058] In a preferred embodiment, Figures 4 to 8 As shown, a pressing piece 223 is fixedly provided on the end surface of the upper mold 220 close to the lower mold 210 at a position corresponding to the connecting piece 160, and a blanking hole 216 that can be plugged into the pressing piece 223 at the corresponding position is fixedly provided on the inner wall of the positioning groove 211 away from the upper mold 220 at a position corresponding to the connecting piece 160.

[0059] Among them, a storage box 218 is detachably provided on the lower mold 210, and the opening of the storage box 218 is connected to the end of the discharge hole 216 away from the upper mold 220. When the lower mold 210 and the upper mold 220 are pressed together, the pressing piece 223 can punch out the connecting pieces 160 between the multiple insert bodies 110, and the connecting pieces 160 detached from the multiple insert bodies 110 can fall into the storage box 218 through the discharge hole 216.

[0060] In a preferred embodiment, Figure 6 As shown, a material discharge channel 217 is provided in the lower mold 210 and is connected to the end of the material discharge hole 216 away from the upper mold 220 , and a guiding inclined wall is provided in the material discharge channel 217 .

[0061] Among them, the storage box 218 is located at one end of the discharge channel 217 away from the discharge hole 216 and the opening is connected to the discharge channel 217. The connecting parts 160 detached from the multiple insert bodies 110 can fall into the storage box 218 through the discharge hole 216 and the guiding inclined wall of the discharge channel 217.

[0062] It is understandable that the detached connector 160 can be guided by the guiding inclined wall on the discharge channel 217, which is conducive to the miniaturized design of the storage box 218, while avoiding the connector 160 from getting stuck in the discharge channel 217, thereby ensuring the discharge stability of the connector 160.

[0063] In a preferred embodiment, it also includes a top mold assembly disposed on the lower mold 210 and / or the upper mold 220.

[0064] It can be understood that after the injection molding of the first transition piece 120 and the second transition piece 130 is completed, the top mold assembly can push the first transition piece 120 and the second transition piece 130 to separate them from the first injection cavity and the second injection cavity, thereby facilitating the demolding and blanking of the finished integrated interface insert structure.

[0065] In a preferred embodiment, a cooling assembly is further included which is arranged on the lower mold 210 and / or the upper mold 220 .

[0066] Among them, the cooling component includes a coolant flow channel arranged in the lower mold 210 and / or the upper mold 220. The coolant flowing in the coolant flow channel can cool the inside of the first injection cavity and the second injection cavity, thereby improving the molding accuracy of the first transition piece 120 and the second transition piece 130.

[0067] like Fig. 9 As shown, an embodiment of the present application provides a housing, including the above-mentioned integrated interface insert structure and a cover body 410 and an interface portion 420 integrally injection-molded on the integrated interface insert structure.

[0068] The integrated interface insert structure is located at a position corresponding to the interface portion 420 .

[0069] It can be understood that since the reinforcement unit is provided on the one-piece interface insert structure, when the one-piece interface insert structure is positioned in the injection mold of the shell, the reinforcement unit can support the one-piece interface insert structure, which can not only improve the positioning stability of the one-piece interface insert structure, but also ensure the overall structural strength of the shell after injection molding.

[0070] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise one..." do not exclude the presence of other identical elements in the process, method, article or device including the element. In addition, it should be pointed out that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in reverse order according to the functions involved, for example, the described method may be performed in an order different from that described, and various steps may also be added, omitted, or combined. In addition, the features described with reference to certain examples may be combined in other examples.

[0071] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
