Description

Technical Field

[0001] This application relates to the field of heat dissipation module manufacturing technology, and in particular to a rivet mold suitable for curved surfaces. Background Technology

[0002] The heat sink consists of several heat sink fins arranged at intervals. The heat-generating element comes into contact with the heat sink fins and transfers heat to them. The heat sink fins form heat dissipation channels, and air flows through these channels to carry away the heat from the fins, thus achieving the heat dissipation function.

[0003] like Figure 1 The heat dissipation module connecting piece shown is used to install on the heat dissipation module. In order to fix it to the laptop later, after the heat dissipation module connecting piece is stamped, two rivets are riveted on its two sides. However, since it has its own curvature, the traditional riveting mold cannot achieve this function. Therefore, this application discloses a riveting mold suitable for curved surfaces.

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0032] In the description of this application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the component or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Example

[0033] To address the issue that existing riveting dies cannot achieve the desired results... Figure 1 The heat dissipation module connecting piece is shown with rivets, for reference. Figure 2 and Figure 5 As shown, in some embodiments, this application discloses a rivet mold suitable for curved surfaces, including a lower mold assembly 10, an upper mold assembly 20, two rivet pressing seats 30 and two rivet pressing parts 40;

[0034] Specifically, the lower mold assembly 10 includes a lower template 11, a lower pad 12, and a lower mold base 13 arranged sequentially from top to bottom, and two riveting seats 30 are respectively disposed inside the lower template 11 and form an obtuse angle.

[0035] Two riveting bases 30 are respectively located inside the lower mold assembly 10, and the upper surfaces of the two riveting bases 30 together form an arc-shaped positioning groove 50 for placing parts.

[0036] The upper mold assembly 20 includes an upper mold base 21, an upper pad 22, an upper clamping plate 23, an upper template 24, and a release plate 25 arranged sequentially from top to bottom. The upper fixing seat 41 is disposed inside the upper clamping plate 23, and the guide seat 42 is disposed inside the release plate 25.

[0037] Two riveting parts 40 are respectively arranged inside the upper die assembly 20, corresponding to two riveting seats 30. The riveting part 40 includes an upper fixed seat 41 disposed inside the upper die assembly 20, a guide seat 42 disposed inside the upper die assembly 20, an upper floating block 43 disposed inside the guide seat 42 and extending outward, a first oblique hole opened inside the upper floating block 43, and a riveting punch 44 disposed below the upper fixed seat 41 and passing through the first guide oblique hole 431.

[0038] In addition, as is known, the upper mold assembly 20 is provided by an external lift (the structure of the external lift is not shown in this application).

[0039] In the case of Figure 1 When riveting the heat dissipation module connecting piece shown, the operator first places the heat dissipation module connecting piece in the arc-shaped positioning groove 50 and inserts two rivets into the two rivet holes of the heat dissipation module connecting piece. Then, the operator controls the external lifting machine to drive the upper mold assembly 20 to descend. At this time, the two upper floating blocks 43 first contact the heat dissipation module connecting piece and press it down. As the upper mold assembly 20 continues to descend, the two upper floating blocks 43 will be compressed to the extreme. At this time, the two riveting punches 44 can rivet the two rivets into the two rivet holes of the heat dissipation module connecting piece.

[0040] In one preferred embodiment, in order to facilitate the removal of the riveted heat dissipation module connecting piece from the arc-shaped positioning groove 50 later, the riveting seat 30 of this application includes a lower fixed seat 31 and a lower floating seat 32. The lower fixed seat 31 and the lower floating seat 32 are arranged one after the other inside the lower mold seat 13. A dovetail block 33 is provided on the lower mold seat 13 corresponding to the lower fixed seat 31 and the lower floating seat 32. A dovetail groove 311 is provided on the lower floating seat 32 to form a mating connection with the dovetail block 33. In the initial state, the lower floating seat 32 is 2-3mm higher than the lower fixed seat 31. After the heat dissipation module connecting piece is riveted, the operator can quickly remove the heat dissipation module connecting piece by pressing the lower floating seat 32 downwards, which is more convenient to use.

[0041] In addition, in order to cooperate with the riveting punch 44 so that the dovetail block 33 avoids the rivet, this application also provides a slot 331 for rivet avoidance inside the dovetail block 33. When the riveting punch 44 rivets the rivet, the lower part of the rivet will be pressed into the slot 331.

[0042] In one preferred embodiment, the guide seat 42 of this application has second guide inclined holes 421 on both sides of the upper floating block 43, and two inclined guide posts 45 are provided below the upper fixed seat 41, which pass through the two second guide inclined holes 421 respectively. When the external elevator drives the upper mold assembly 20 to rise and fall, the two inclined guide posts 45 will move in the two second guide holes 421. In this way, the riveting punch 44 can be guaranteed to move smoothly, improving the riveting accuracy of the rivet and having strong practicality.

[0043] In addition, this application also provides a T-shaped guide groove 422 inside the guide seat 42, and the upper floating block 43 is arranged in a T-shaped structure inside the T-shaped guide groove 422. Based on this design, in specific implementation, the upper floating block 43 can stably rise and fall within the guide seat 42. In order to ensure that the upper floating block 43 does not lift up when pressing the heat dissipation module connecting piece before the riveting punch 44 presses the rivet, this application provides an arc-shaped surface 432 at the bottom of the upper floating block 43 that is consistent with the part.
