Description

Technical Field

[0001] The utility model relates to the technical field of accessories for automobile air - conditioning systems, and particularly relates to an insert die - cast flange. Background Art

[0002] A flange is a commonly used air - conditioning pipeline accessory in an automobile air - conditioning system. Currently, the existing flanges are generally formed by aluminum die - casting for the whole flange. However, when the airtightness of the flanges processed by this forming method is detected, air leakage occurs at the positions of two pipeline connection holes of some flanges, resulting in the problem of unqualified airtightness detection, so they cannot be used.

[0003] Therefore, in view of the above problems, we provide an insert die - cast flange to prevent air leakage of parts and ensure the qualification rate of parts. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide an insert die - cast flange, which solves the problems that the existing flanges are formed by aluminum die - casting for the whole flange and there are air leakage and unqualified airtightness detection.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: An insert die - cast flange includes a flange body. A plurality of bolt mounting holes are provided on the flange body. An insert one and an insert two for connecting pipelines are respectively embedded on the flange body. The central hole one of the insert one is machined into a hole with a diameter of 9.5 along the axial direction. The threaded part one at the tail of the insert one is turned to 17.0. Concave flats one and two are respectively arranged on the circumferential side of the insert one above the threaded part one. The central hole two of the insert two is machined into holes with diameters of 12.5 and 9.5 along the axial direction. The threaded part two at the tail of the insert two is turned to 17.0. Concave flats three and four are respectively arranged on the circumferential side of the insert two above the threaded part two. Convex blocks matching the shapes of flats one, two, three and four are respectively formed on the side walls of the insert mounting positions of the flange body.

[0006] Preferably, the bolt mounting holes are distributed around the insert one and the insert two.

[0007] Preferably, the flange body is diamond - shaped, and the bolt mounting holes are distributed at the corners and the center of the flange body.

[0008] Preferably, flats one and two are arranged at a 90° stagger on the circumferential side of the insert one, and flats three and four are arranged at a 90° stagger on the circumferential side of the insert two.

[0009] Preferably, both the insert one and the insert two are in a T - shape, and the heads of the insert one and the insert two are embedded on the flange body.

[0010] Preferably, the flange body is aluminum injection-molded in the mold together with the insert one and the insert two placed in the mold.

[0011] Preferably, a connecting block is provided at the top of the flange body to connect the insert one and the insert two.

[0012] The utility model has the following beneficial effects:

[0013] By providing the insert one and the insert three on the flange body, the utility model overcomes the defects of the traditional flange. During die-casting, the positions of the two pipeline connection holes of the flange are changed into two inserts, and these two inserts are placed in the mold and aluminum injection-molded together with the flange body. After the insert one and the insert two are formed, the whole is stable and easy to be finely processed. Moreover, the consumables of the modified flange body are reduced. It not only eliminates the problem of part air leakage, but also has a simple structure and is easy to manufacture, thus ensuring the qualified rate of parts and improving the production efficiency.

[0021] Such as Figures 1-5As shown in the figure, the utility model provides a technical solution: an insert die-cast flange, which includes a flange body 1. The flange body 1 is diamond-shaped. There are multiple bolt mounting holes 11 on the flange body 1. An insert one 2 and an insert two 3 for connecting pipelines are respectively embedded on the flange body 1. The insert one 2 and the insert two 3 are made of 6061 alloy material, which has medium strength, good corrosion resistance, weldability, and excellent oxidation effect. The insert one 2 and the insert two 3 are more stable when connected to the air-conditioning system pipeline. And the bolt mounting holes 11 are distributed at the corners and the center of the flange body 1, and the bolt mounting holes 11 are distributed around the insert one 2 and the insert two 3. Both the insert one 2 and the insert two 3 are in a T shape, and the heads of the insert one 2 and the insert two 3 are embedded in the flange body 1.

[0022] A connecting block 14 is arranged at the top of the flange body 1 to connect the insert one 2 and the insert two 3. The connecting block 14 semi-surrounds the insert one 2 and the insert two 3, and the tops are flush. The flange body 1 is aluminum die-cast in the mold together with the insert one 2 and the insert two 3 placed in the mold. The central hole one 21 of the insert one 2 is machined axially into a hole with a diameter of 9.5 to reduce the machining allowance and prevent the insert from rotating during machining. The central hole one 21 of the insert one 2 is machined into a hole with a diameter of 10.15 by subsequent machining. The threaded part one 22 at the tail of the insert one 2 is turned to 17.0 to reduce the machining allowance and prevent the insert from rotating during machining. The thread of the threaded part one 22 is formed by subsequent machining. Concave flats one 23 and two 24 are respectively arranged on the circumferential side of the insert one 2 above the threaded part one 22. The flats one 23 and two 24 are arranged at a 90° stagger on the circumferential side of the insert one 2. Flats are added here to prevent the part from loosening and rotating.

[0023] The central hole two 31 of the insert two 3 is machined axially into holes with diameters of 12.5 and 9.5 to reduce the machining allowance and prevent the insert from rotating during machining. The central hole two 31 of the insert two 3 is machined into holes with diameters of 18.3 and 10.15 by subsequent machining. The threaded part two 32 at the tail of the insert two 3 is turned to 17.0 to reduce the machining allowance and prevent the insert from rotating during machining. The thread of the threaded part two 32 is formed by subsequent machining. Concave flats three 33 and four 34 are respectively arranged on the circumferential side of the insert two 3 above the threaded part two 32. The flats three 33 and four 34 are arranged at a 90° stagger on the circumferential side of the insert two 3. Flats are added here to prevent the part from loosening and rotating.
