[0023] The technical solutions in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model.​​​​​​​​

[0024] As Figures 1 to 9 shown in the utility model discloses electronic equipment parts injection mould, including mould concrete 1, mould concrete 1 is equipped with lower mould plate 2, the other structure of mould concrete 1 can adopt prior art, not do much elaboration here.

[0025] The middle of lower mould plate 2 is equipped with lower mould cavity 3, and the middle of lower mould cavity 3 is equipped with lower mould core 4, and the middle of lower mould core 4 is equipped with lower core cavity 41. A sliding chamber 5 is arranged on the lower mould core 4, and the sliding chamber 5 is communicated with the limiting chamber 7 through the movable area 6. The width of the movable area 6 is greater than the distance between the positioning arm 8 and the vertical section 9, so that when the limiting part 10 slides in the movable area 6, the positioning arm 8 can be moved out of the positioning chamber 11.

[0026] The two sides of the lower mould core 4 are equipped with a limiting chamber 7, and the inner wall of the lower mould cavity 3 is equipped with a positioning chamber 11 corresponding to the limiting chamber 7. A limiting part 10 is arranged in the limiting chamber 7 and the positioning chamber 11, and the limiting part 10 is installed in the limiting chamber 7. A positioning arm 8 is arranged on the limiting part 10, and the positioning arm 8 extends into the positioning chamber 11.

[0027] The limiting part 10 is composed of a sliding section 12, a vertical section 9 and an installation section 13. The sliding section 12 is installed in the sliding chamber 5, the vertical section 9 and the installation section 13 are arranged in the limiting chamber 7, and the installation section 13 and the vertical section 9 form a compression area 14. A stamping hole 15 is arranged on the vertical section 9, and the positioning arm 8 is arranged in the stamping hole 15.

[0028] Elastic arms 16 are arranged on the two sides of the installation section 13, and the length of the elastic arms 16 is greater than the height of the limiting chamber 7. The elastic arms 16 are arranged in the limiting chamber 7 in an arc shape under stress. Before installation, the elastic arms 16 are arranged in parallel with the installation section 13 and on both sides of the installation section 13. When installation is needed, the elastic arms 16 are deformed under stress to form an arc shape, and then they are placed in the limiting chamber 7, so that the shorter height of the limiting chamber 7 limits the longer elastic arms 16 in the limiting chamber 7.

[0029] A reinforcing block 17 is arranged between the vertical section 9 and the installation section 13, which can avoid the deformation of the connection between the vertical section 9 and the installation section 13 under stress when the sliding section 12 drives the vertical section 9 to move.

[0030] A recess hole 18 is arranged between the sliding section 12 and the vertical section 9, which can facilitate the staff to push the limiting part 10 by hand and facilitate the positioning arm 8 to move out of the positioning chamber 11.

[0031] The installed elastic arm 16 can push the vertical section 9 to the opening of the limiting chamber 7 under its own elasticity, and when the push recess hole 18 is pushed, the sliding section 12 can drive the vertical section 9 to push the mounting section 13, so that the mounting section 13 is deformed under stress, and gradually changes into an arc similar to the elastic section, at this time, the positioning arm 8 moves out of the positioning chamber 11, and the lower mold core 4 can be taken out from the lower mold cavity 3. The limiting piece 10 on the lower mold core 4 is taken off and replaced on the new lower mold core 4, and the new replaced lower mold core 4 is installed into the lower mold cavity 3 again.

[0032] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
