[0022] The utility model provides a technical solution: Figures 1 to 5 As shown, in the present embodiment, a movable reserved hole mechanism for injection molding of a router shell comprises a bottom mold 1, a mold groove 2 is provided on the upper surface of the bottom mold 1, a router shell body 3 is arranged in the mold groove 2, a reserved hole body 15 is arranged on the router shell body 3, a reserved hole module 7 acting on the reserved hole body 15 is arranged in the mold groove 2, the number of the reserved hole modules 7 is four and they are distributed in pairs in two mounting grooves 6 opened at the bottom of the mold groove 2, an adjustment mechanism acting on the reserved hole module 7 is arranged in the mounting groove 6, the adjustment mechanism consists of a positioning block 5 and a clamping block 8, two clamping blocks 8 are slidably installed in the mounting groove 6, two reserved hole modules 7 are located between the two clamping blocks 8, one end of the clamping block 8 away from the reserved hole module 7 is connected to a driving mechanism, a positioning block 5 is arranged between the two reserved hole modules 7, and the positioning block 5 is slidably fitted with the mounting groove 6.

[0023] The upper surfaces of the positioning block 5 , the reserved hole module 7 and the clamping block 8 are aligned with the bottom of the mold cavity 2 .

[0024] Such an arrangement can ensure that the bottom of the mold cavity 2 will not be uneven.

[0025] Among them, the driving mechanism is composed of a fixed plate 4, an adjusting screw 11 and a rotating part 12. The adjusting screw 11 is inserted into the inside of the clamping block 8 and is connected to the clamping block 8 through threaded cooperation. The protruding end of the adjusting screw 11 is rotatably connected to the fixed plate 4, and the fixed plate 4 is fixedly connected to the side wall of the bottom mold 1. The side wall of the fixed plate 4 is rotatably connected to the rotating part 12, and the rotating part 12 is fixedly connected to the adjusting screw 11.

[0026] When in use, the rotating member 12 is rotated to drive the adjusting screw 11 to rotate, thereby controlling the clamping block 8 to move in the installation groove 6 and controlling the two clamping blocks 8 to approach each other, so that the reserved hole module 7 between the two clamping blocks 8 can be clamped.

[0027] A plurality of anti-skid grooves are formed on the outer wall of the rotating member 12 , and the plurality of anti-skid grooves are distributed in a ring array.

[0028] The anti-slip groove can increase the friction between the hand and the rotating member 12 .
