[0028] Example
[0029] Reference Figure 1-6 A mouse scroll wheel injection molding equipment includes a fixed mold 1 and a movable mold 2. The fixed mold 1 has a detachable fixed core 7, and the movable mold 2 has a detachable fixed core 8 corresponding to the fixed core 7. By setting the fixed core 7 and the movable core 8, when injection molding mouse scroll wheels of the same model with different appearances are required, the fixed core 7 and the movable core 8 can be replaced individually. This way, during the initial mold development, only the fixed core 7 and the movable core 8 with different appearances need to be developed separately, avoiding the hassle of developing different complete molds for mouse scroll wheels with different appearances.
[0030] In this embodiment, the fixed mold 1 and the moving mold 2 are each provided with a U-shaped mounting cavity 3, a positioning hole 4 and an insertion hole 5, so as to provide the necessary mounting space for the fixed mold core 7 and the moving mold core 8, and to ensure the stability of the fixed mold core 7 and the moving mold core 8 after installation. The U-shaped mounting cavity 3, the positioning hole 4 and the insertion hole 5 are connected. The opening of the U-shaped mounting cavity 3 faces the outside of the corresponding fixed mold 1 and the moving mold 2, so as to disassemble and assemble the fixed mold core 7 and the moving mold core 8. The positioning hole 4 is located at the closed end of the U-shaped mounting cavity 3, and the insertion hole 5 is above the positioning hole 4. The insertion hole 5 is coaxial with the positioning hole 4.
[0031] The fixed mold core 7 is detachably and fixedly installed in the U-shaped mounting cavity 3, positioning hole 4 and insertion hole 5 on the fixed mold 1;
[0032] The moving mold core 8 is detachably and fixedly installed in the U-shaped mounting cavity 3, positioning hole 4 and insertion hole 5 on the moving mold 2.
[0033] In this embodiment, two integrated T-shaped guide rails 6 are provided in the U-shaped mounting cavity 3 of the fixed mold 1 and the moving mold 2, and the two T-shaped guide rails 6 are arranged in a mirror position with the positioning hole 4 as the center.
[0034] The fixed mold core 7 is slidably connected to the T-shaped guide rail 6 in the U-shaped mounting cavity 3 of the fixed mold 1. The T-shaped guide rail 6 in the fixed mold 1 can limit the fixed mold core 7, ensuring the accuracy and stability of the fixed mold core 7 after installation.
[0035] The moving mold core 8 is slidably connected to the T-shaped guide rail 6 in the U-shaped mounting cavity 3 of the moving mold 2. The T-shaped guide rail 6 in the moving mold 2 can limit the movement of the moving mold core 8, ensuring the accuracy and stability of the moving mold core 8 after installation.
[0036] In this embodiment, a roller mold cavity 9 is provided on the upper surface of the fixed mold core 7, and a positioning structure is fixedly installed at the front end of the fixed mold core 7. Through the setting of the positioning structure, the corresponding fixed mold core 7 and moving mold core 8 can be detachably fixedly installed on the corresponding fixed mold 1 and moving mold 2. The bottom surface of the fixed mold core 7 is provided with two T-shaped grooves 15 corresponding to the T-shaped guide rail 6. The two T-shaped grooves 15 are set in a mirror position with the positioning structure as the center. The T-shaped grooves 15 are slidably connected with the corresponding T-shaped guide rail 6 so that the fixed mold core 7 and moving mold core 8 can be positioned and disassembled with the corresponding fixed mold 1 and moving mold 2. The positioning structure is engaged with the corresponding positioning hole 4 and insertion hole 5.
[0037] The only difference between the moving mold core 8 and the fixed mold core 7 is that the moving mold core 8 has a moving mold cavity 10 corresponding to the fixed mold cavity 9 of the roller. The setting of the fixed mold cavity 9 and the moving mold cavity 10 of the roller is used to form the complete mold cavity required for the injection molding of the mouse roller.
[0038] In this embodiment, the positioning structure includes a positioning block 11, a circular cavity 12, a compression spring 13, and a pin 14. The positioning block 11 is fixedly installed at one end of the corresponding fixed mold core 7 and moving mold core 8. The positioning block 11 has a circular cavity 12. The circular cavity 12 provides the necessary moving space for the pin 14 and ensures the stability of the pin 14 during movement. The pin 14 is elastically slidably installed in the circular cavity 12 through the compression spring 13. The pin 14 and the compression spring 13 are used to connect or separate the pin 14 from the insertion hole 5. One end of the compression spring 13 is fixedly connected to the positioning block 11, and the other end of the compression spring 13 is fixedly connected to the bottom end of the pin 14. The positioning block 11 is inserted into the corresponding positioning hole 4, and the pin 14 is inserted into the corresponding insertion hole 5. The depth of the circular cavity 12 is greater than the length of the pin 14. After the compression spring 13 is fully compressed, the pin 14 can be completely hidden in the circular cavity 12.
[0039] In practical use, this utility model is used, taking the installation of the fixed mold core 7 as an example:
[0040] The T-slot 15 on the fixed mold core 7 is slidably connected to the T-slot guide rail 6 in the U-shaped mounting cavity 3 of the fixed mold 1. When the positioning structure on the fixed mold core 7 approaches the positioning hole 4, the insert post 14 is pressed down, causing the insert post 14 to retract into the circular cavity 12, so that the positioning block 11 enters the positioning hole 4. When the positioning block 11 is fully inserted into the positioning hole 4, the insert post 14 will be coaxially aligned with the insertion hole 5. Under the action of the compression spring 13, the insert post 14 will enter the insertion hole 5. At this time, the fixed mold core 7 is firmly fixed on the fixed mold 1.
[0041] When it is necessary to replace the fixed mold core 7, press down the insert post 14 to retract the insert post 14 back into the cavity 12, and at the same time pull out the fixed mold core 7.
[0042] The moving mold core 8 can be installed and replaced using the methods described above.
[0043] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
