Description

Technical Field

[0001] This utility model relates to the field of press-fitting molds, specifically to a press-fitting mold for copper tubes on a communication device housing. Background Technology

[0002] With the development of 5G technology, the heat dissipation requirements of communication equipment are becoming increasingly stringent. Existing communication device housings primarily dissipate heat through external heat dissipation fins. However, different heat dissipation units within the housing generate varying amounts of heat, and as shown in the diagram, relying solely on heat dissipation fins can easily lead to localized overheating. Therefore, it is typically necessary to press-fit copper tubes inside the heat sink housing. The heat is then rapidly transferred to other lower-temperature areas of the communication device housing via a heat-conducting medium within the copper tubes. The communication housing is mainly composed of die-cast aluminum alloy parts. The copper tubes need to be press-fitted after the communication housing has been machined. Current pressing methods primarily involve individual pressing using a press. To prevent the copper tubes from gradually deforming and becoming completely embedded in the communication housing during the pressing process, multiple press heads with different structures are required for multiple pressing operations. Using existing technology necessitates constant head changes, resulting in low pressing efficiency, high skill requirements for pressing workers, and inconsistent pressing quality. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this utility model provides a copper tube pressing mold for a communicator housing, which enables automatic multiple pressing of copper tubes onto the communicator housing, resulting in high pressing efficiency and good pressing quality.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

The third cylinder has a first pressure block connected to the lower end of the piston rod of the first cylinder, a second pressure block connected to the lower end of the piston rod of the second cylinder, and a third pressure block connected to the lower end of the piston rod of the third cylinder. The inverted mounting base is provided with a horizontally movable first positioning block, a second positioning block, and a third positioning block. When the sliding plate abuts against the first positioning block, the first pressure block is aligned with the copper tube pressing position on the communicator housing.

The bottom surface of the upper mold plate 5 is provided with two oppositely arranged inverted mounting seats 6, and two parallel linear guide rails 7 are provided on the two inverted mounting seats 6.

The inverted mounting base 6 is equipped with a horizontally movable first positioning block 18, a second positioning block 19, and a third positioning block 20. The first positioning block 18 is located behind the sliding plate 8, and when the sliding plate 8 abuts against the first positioning block 18, the first pressure block 15 is aligned with the copper tube pressing position on the communicator housing, thus enabling the first step of pressing. The second positioning block 19 and the third positioning block 20 are located in front of the sliding plate 8, and when the sliding plate 8 abuts against the second positioning block 19, the second pressure block 16 is aligned with the copper tube pressing position on the communicator housing, thus enabling the second step of pressing. And when the sliding plate 8 abuts against the third positioning block 20, the third pressure block 17 is aligned with the copper tube pressing position on the communicator housing, thus enabling the third step of pressing.

The guide components include guide posts 21 on the lower mold plate 1 and guide sleeves 22 on the upper mold plate 5. The guide sleeves 22 and guide posts 21 are arranged coaxially.

[0018] To facilitate quick positioning and installation of the communicator housing, the lower template 1 is provided with end limiting blocks 23 around the perimeter of the communicator housing. The upper end of the end limiting block 23 has a guide slope, which allows the communicator housing to be quickly positioned on the first positioning post 2 and the second positioning post 3.

Each of the three positioning blocks has a drive cylinder 25 at its rear end. The drive cylinder 25 is mounted on the side of the upper template 5 via a suspension plate 26. During the first pressing step, the first positioning block 18 extends, and the sliding plate 8 moves backward so that the rear end of the sliding plate 8 contacts the first positioning block 18. Similarly, during the second pressing step, the second positioning block 19 extends, and during the third pressing step, the third positioning block 20 extends.

[0021] To ensure high vertical movement accuracy of the three pressure blocks and prevent rotation, guide rods 27 that slide in conjunction with the sliding plate 8 are provided on the first pressure block 15, the second pressure block 16, and the third pressure block 17.

[0022] To facilitate the control of the actions of the first cylinder 11, the second cylinder 12, and the third cylinder 14, a sensor 28 is provided at the bottom of the upper template 5. The sensor 28 is mounted on the bottom surface of the upper template 5 via a sensor mounting base 29.
