[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figures 1 to 3 The utility model provides a technical solution: a gear process hole chamfering mold, including a base 1, a placing column 11 is installed on the top of the base 1, and a lower mold base 12 is installed on the top of the placing column 11, six groups of processing holes 13 are arranged at the edge of the top of the lower mold base 12, and a positioning rod 14 is installed at the middle of the top of the lower mold base 12, a gear body 4 is placed on the top surface of the lower mold base 12, and the gear body 4 is sleeved on the outer surface of the positioning rod 14.

[0018] A support plate 2 is installed on one side of the base 1, and a slide groove 21 is opened at the middle position of the side surface of the support plate 2, a top plate 22 is installed at the top position of one side of the support plate 2, and an electric push rod 3 is installed at one end of the top plate 22, a through hole is opened in the top plate 22 near the position of the electric push rod 3, and the bottom end of the electric push rod 3 passes through the inside of the top plate 22 through the through hole.

[0019] An upper die seat 31 is installed at the bottom end of the electric push rod 3, and a sliding rod 32 is installed on the side of the upper die seat 31. The width of the sliding rod 32 is adapted to the distance between the inner walls on both sides of the corresponding slide groove 21, and one end of the sliding rod 32 extends into the interior of the slide groove 21 and is slidably connected thereto. Six groups of chamfered columns 33 are installed at the bottom end of the upper die seat 31. The size of the six groups of processed holes 13 is equal to the size of the six groups of chamfered columns 33, and the six groups of processed holes 13 and the six groups of chamfered columns 33 are arranged in a one-to-one correspondence.

[0020] During use, the user can place the gear body 4 on the top surface of the lower die seat 12 and overlap it with the top surfaces of the six groups of processing holes 13, and at the same time sleeve it on the outer surface of the positioning rod 14, so as to play a role of positioning and placement. After that, the user can start the electric push rod 3, so that under the operation of the electric push rod 3, the upper die seat 31 can move downward accordingly, so that the six groups of chamfering columns 33 can move downward accordingly. When the bottom surface of the upper die seat 31 is fitted with the top surface of the gear body 4, the six groups of chamfering columns 33 will be respectively located in the corresponding process holes in the gear, so that the inside of the corresponding process holes can be chamfered respectively, and the bottom surfaces of the six groups of chamfering columns 33 will eventually be respectively in the corresponding processing holes. The top surface of 13 is arranged in a fit relationship. During the downward movement of the upper die seat 31, one end of the slide rod 32 will move downward accordingly inside the slide groove 21, so that the upper die seat 31 is more stable and less likely to shake when moving downward. When the chamfering operation of the process hole inside the gear body 4 is completed, the user can use the electric push rod 3 to move the upper die seat 31 upward to the initial height. At this time, the gear body 4 can be taken away from the top surface of the lower die seat 12 accordingly. The above-mentioned arrangement and operation can effectively solve the problem that the existing process hole chamfering mold cannot conveniently position and place the gear body 4 during the chamfering process of the gear body 4, and the upper and lower molds will shake during the processing, thereby affecting the chamfering process.
