With the advent of the information age, the Internet of Everything has become a major industry development trend. Among them, the importance and attention of wireless signal transmission are getting higher and higher. There are many types of wireless products according to power, and the most common ones are home routers and commercial routers.

As the requirements for wireless signal quality increase, the power of the router increases, so that the router generates more heat, which is concentrated in the router. In order to dissipate heat from the router, there are cooling holes on the side of the router shell to facilitate heat dissipation. For safety reasons, the size of the heat dissipation hole will be limited by the industry standard (currently about 0.8mm). When the diameter of the hole cannot be increased, the design of the heat dissipation hole becomes particularly important.

The cooling holes and the wiring interface of the router are designed on the same side, and the gap between the two holes is only one product wall thickness. The wiring interface outputs the wiring to the outside, and the heat of the cooling holes is released from the inside to the outside. The angle of the cooling holes is large inside and small outside. , so that the two directions of the wiring holes are exactly opposite.

In actual production, in order to process the casing of this type of router, a mold is needed. The side of the casing is provided with a hole, which becomes an undercut part on the corresponding mold. Due to the asymmetry of the router itself, the position of the heat dissipation hole and the wiring hole is due to the The hole has a large holding force, and because the opposite sides of the heat dissipation hole and the wiring hole are flat (no holes), there is no holding force, so the holding force of the router shell to the mold is different, resulting in the shell will be removed from the mold. side movement (the side that holds the most force), which will scratch the casing of the machined router.
