AI Technical Summary
During the processing of a box with knock-out holes, insufficient flow is likely to occur at the knock-out holes, resulting in poor die-casting of the hole cover. In the later stage, the wire is easily cut by the hole wall when using the knock-out holes to line.
A box is designed, with knocking holes on the main body, and the knocking holes are located on the thickened part of the material. The thickened part of the material is in the shape of a bottle opener, including guide branches, trapezoidal branches and concave branches. The easily broken structure divides the plate part into the first connecting part and the second connecting part through the pre-cut groove, connecting the thickened part of the material and the hole cover.
Through the design of the material thickening part, the material thickness around the knock-out hole is increased, the problem of insufficient flow material is improved, and the production quality of the hole cover is improved. At the same time, the increased structural strength prevents the box from deforming, improves the phenomenon of wire being cut, and improves the safety and reliability of the product.
