[0027] In subsequent use, when different specifications of the lower die 2 and the upper die 3 need to be replaced, only the servo motor is started in a forward direction, the output shaft of the servo motor drives the double-headed threaded rod 13 to rotate, so that the two transverse moving plates 14 move in a direction away from each other, at this time, the two mounting strips 16 move in a direction away from each other under the drive of the frame connecting rod 15, and at the same time, the two rectangular strips 19 also move in a direction away from each other under the drive of the hollow column 18, until the two first embedding rods 17 are taken out of the corresponding second embedding grooves 11 and the two second embedding rods 20 are taken out of the corresponding first embedding grooves 9, the servo motor is turned off, at this time, the lower die 2 and the upper die 3 are no longer limited by the transverse clamping, then the output shaft of the hydraulic cylinder 4 is retracted, the lower mounting plate 5 takes the lower die 2 and the upper die 3 down, the two upper connecting blocks 10 are moved out of the corresponding rectangular through grooves 7, then the upper die 3 is directly taken off, then the lower die 2 is pulled up, the two lower connecting blocks 8 are pulled out of the corresponding rectangular through grooves 7.

[0028] Then the corresponding lower die 2 and upper die 3 are taken out, the lower connecting blocks 8 on the lower die 2 are inserted into the corresponding rectangular through grooves 7, then the upper connecting blocks 10 on the upper die 3 are inserted into the corresponding rectangular through grooves 7, then the servo motor is started in a reverse direction, the two mounting strips 16 move in a direction close to each other, finally the two first embedding rods 17 are inserted into the corresponding second embedding grooves 11 and the two second embedding rods 20 are inserted into the corresponding first embedding grooves 9, then the output shaft of the hydraulic cylinder 4 is extended, so that the lower die 2 and the upper die 3 abut.

[0029] Compared with the related art, the toothbrush handle injection molding mold has the following beneficial effects:

[0030] The first embedding groove 9, the second embedding groove 11, the first embedding rod 17 and the second embedding rod 20 are arranged, so that the positioning effect of the lower connecting block 8 and the upper connecting block 10 can be formed by controlling the operation of the servo motor, the lower die 2 and the upper die 3 can be quickly installed and fixed, and when the lower die 2 and the upper die 3 are replaced later, only the servo motor needs to be started to take the first embedding rod 17 out of the second embedding groove 11 and take the second embedding rod 20 out of the first embedding groove 9, so that the lower die 2 and the upper die 3 can be replaced, which brings great convenience to the replacement of the mold, compared with the traditional bolt assembly, the replacement mode of the mold is more quick, and the injection molding efficiency is effectively improved.
