[0002] A router is a network device used to connect multiple networks or network segments and forward data information between different networks. The router itself consists of two parts: the outer shell and the control element. The router shell is generally a plastic shell and is usually manufactured by injection molding.

[0003] In the prior art, the internal fixed structures of router shells of the same size produced by the same manufacturer are roughly the same, and most of the changes are only to the outer shape of the shell. However, during production, an integrated mold is generally used. In this way, although the internal structure does not change, a set of molds needs to be produced separately for each shell. Therefore, when producing a new shell, a new mold needs to be produced for the new shell. Since the new mold needs to be modified many times during the development process, the production cost will be greatly increased if a new set of molds is produced each time. Therefore, an injection mold for producing router shells is proposed to solve the above problem. Utility Model Content

[0032] Reference Figure 1 - Figure 3The locking assembly 52 includes a block 521 for blocking the pull handle 516. The block 521 is set to be L-shaped. The left end of the pull rod 514 is rotatably connected to the pull handle 516. By pulling the pull handle 516, the pull rod 514 can be driven to move. The pull handle 516 is inserted into the inside of the block 521. When the pull handle 516 is inside the block 521, the pull handle 516 will be restricted from moving to the left. The right end of the block 521 is fixedly connected to a rubber block 522 for fixing the pull handle 516. The left end of the pull handle 516 is provided with a positioning groove 523 for accommodating the rubber block 522. The rubber block 522 is inserted into the inner wall of the positioning groove 523. When the rubber block 522 is inside the positioning groove 523, the rubber block 522 will squeeze the inner wall of the positioning groove 523 so that the pull handle 516 cannot move at will. The block 52 1. There are multiple groups of rubber blocks 522 and positioning grooves 523. The multiple groups of blocks 521, rubber blocks 522, and positioning grooves 523 are arranged in a rotation array with the center line of the pull handle 516 as the rotation axis.
