[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-6 This utility model provides a technical solution: A precision terminal crimping mold includes an upper mold 1, a crimping groove 2 formed at the bottom of the upper mold 1, and a lower mold 3. The crimping groove 2 is directly opposite the lower mold 3, and the dimensions of the crimping groove 2 are adapted to the dimensions of the lower mold 3. A sleeve plate 4 is provided on the side of the upper mold 1, and a spring 5 is provided inside the sleeve plate 4. A movable plate 6 is vertically slidably arranged on the sleeve plate 4. The two ends of the spring 5 are respectively fixedly installed to the sleeve plate 4 and the movable plate 6. An insertion port 7 is formed on the side of the upper mold 1, and an insertion plate 8 is fixedly installed on the top side of the sleeve plate 4. The size of the insert plate 8 is adapted to the size of the socket 7. The upper mold 1 and the insert plate 8 are provided with fixing members 9. The fixing members 9 include an installation port 91 opened on the side of the insert plate 8, a spring 92 set in the installation port 91, a fixing block 93 slidably set on the installation port 91, and a fixing port 94 opened on the upper mold 1 located on the side of the socket 7. The two ends of the spring 92 are fixedly installed to the insert plate 8 and the fixing block 93 respectively. The fixing block 93 and the fixing port 94 are set as matching arc surfaces.

[0020] In the precision terminal crimping mold, the lower mold 3 is a metal plate used to support the wire harness and the terminal, and the upper mold 1 is a punch. The upper mold 1 can be driven vertically by a conventional cylinder or other driving device. The pressing groove 2 at the bottom of the upper mold 1 is used to cooperate with the lower mold 3 to achieve precision crimping of the wire harness and the terminal. During the vertical descent of the upper mold 1 for crimping, the sleeve plate 4 and the movable plate 6 set on the side of the upper mold 1 descend vertically together with the upper mold 1. During the descent of the movable plate 6, it will come into contact with the wire harness on the lower mold 3, which will cause the movable plate 6 to compress the spring 5 and move into the sleeve plate 4. After the crimping is completed, the upper mold 1 rises vertically. Through the elastic restoring force of the spring 5, the movable plate 6 is pushed vertically downward. The movable plate 6 will then push the wire harness and push the crimped terminal out of the crimping groove 2 at the bottom of the upper mold 1. When installing the movable plate 6, the operator inserts the insert plate 8 on the side of the sleeve plate 4 into the insertion port 7 on the side of the upper mold 1. During the insertion of the insert plate 8 into the insertion port 7, the fixing block 93 is compressed by the pressure of the spring 92 and enters the installation port 91. When the insert plate 8 is fully inserted into the insertion port 7, the installation port 91 is aligned with the fixing port 94. The elastic restoring force of the spring 92 causes the fixing block 93 to be locked into the fixing port 94, thus completing the installation and fixing of the insert plate 8, sleeve plate 4, and movable plate 6. Conversely, the operator pulls the insert plate 8 outward through the sleeve plate 4, causing the fixing block 93 to retract and disengage from the fixing port 94, so that the insert plate 8, sleeve plate 4, and movable plate 6 can be removed for easy replacement. This precision terminal crimping mold can automatically push the terminal out of the crimping groove 2 of the upper mold 1 after the terminal crimping is completed, effectively preventing the terminal from getting stuck in the crimping groove 2 of the mold, effectively improving the terminal crimping efficiency, saving time and effort, and is highly practical.

[0021] At least two sets of symmetrical mounting ports 91, spring 92, fixing block 93, and fixing ports 94 are provided. The mounting port 91, spring 92, fixing block 93, and fixing port 94 are provided with at least two symmetrical sets, which can improve the stability of the insert plate 8, sleeve plate 4, and movable plate 6 after installation and fixing, thereby ensuring the stability of pushing material.

[0022] The bottom edge of the movable board 6 is set as a curved edge; The bottom edge of the movable plate 6 is set as an arc edge, which can better fit the wire harness and push the wire harness, further improving the stability of pushing the material.

[0023] The dimensions of movable plate 6 are compatible with the inner diameter of sleeve plate 4; The size of the movable plate 6 is compatible with the inner diameter of the sleeve plate 4, which can also improve the stability of pushing materials.

[0024] Working principle: In the precision terminal crimping mold, the lower mold 3 is a metal plate used to support the wire harness and the terminal, and the upper mold 1 is a punch. The upper mold 1 can be driven vertically by a conventional cylinder or other driving device. The pressing groove 2 at the bottom of the upper mold 1 is used to cooperate with the lower mold 3 to achieve precision crimping of the wire harness and the terminal. During the vertical descent of the upper mold 1 for crimping, the sleeve plate 4 and the movable plate 6 set on the side of the upper mold 1 descend vertically together with the upper mold 1. During the descent of the movable plate 6, it will come into contact with the wire harness on the lower mold 3, which will cause the movable plate 6 to compress the spring 5 and move into the sleeve plate 4. After the crimping is completed, the upper mold 1 rises vertically. Through the elastic restoring force of the spring 5, the movable plate 6 is pushed vertically downward. The movable plate 6 will then push the wire harness and push the crimped terminal out of the crimping groove 2 at the bottom of the upper mold 1. When installing the movable plate 6, the operator inserts the insert plate 8 on the side of the sleeve plate 4 into the insertion port 7 on the side of the upper mold 1. During the insertion of the insert plate 8 into the insertion port 7, the fixing block 93 is compressed by the pressure of the spring 92 and enters the installation port 91. When the insert plate 8 is fully inserted into the insertion port 7, the installation port 91 is aligned with the fixing port 94. The elastic restoring force of the spring 92 causes the fixing block 93 to be locked into the fixing port 94, thus completing the installation and fixing of the insert plate 8, sleeve plate 4, and movable plate 6. Conversely, the operator pulls the insert plate 8 outward through the sleeve plate 4, causing the fixing block 93 to retract and disengage from the fixing port 94, so that the insert plate 8, sleeve plate 4, and movable plate 6 can be removed for easy replacement. This precision terminal crimping mold can automatically push the terminal out of the crimping groove 2 of the upper mold 1 after the terminal crimping is completed, effectively preventing the terminal from getting stuck in the crimping groove 2 of the mold, effectively improving the terminal crimping efficiency, saving time and effort, and is highly practical. in, The mounting port 91, spring 2 92, fixing block 93, and fixing port 94 are provided with at least two symmetrical sets, which can improve the stability of the insert plate 8, sleeve plate 4, and movable plate 6 after installation and fixing, thereby ensuring the stability of pushing material. The bottom edge of the movable plate 6 is set as an arc edge, which can better fit the wire harness and push the wire harness, further improving the stability of pushing the material; The size of the movable plate 6 is compatible with the inner diameter of the sleeve plate 4, which can also improve the stability of pushing materials.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
