The first module 1 and the second module 2 are injection molds for plastic wire spool products that match each other in the prior art. A sliding groove 3 is opened inside the second module 2. A forming sleeve 4 that matches it is slidably connected inside the sliding groove 3. A forming groove 5 is opened on the surface of the forming sleeve 4. A sliding groove 6 is opened on the bottom surface of the forming sleeve 4. A moving groove 7 is opened on the inner wall of the sliding groove 3. A roller 8 that matches it is rotatably connected inside the moving groove 7 and the sliding groove 6. The roller 8 ensures the stable movement of the forming sleeve 4. A rotating plate 9 is rotatably connected between the two rollers 8. A spring seat 10 is fixedly installed on the inner wall of the middle part of the sliding groove 6. A spring 11 is arranged inside the spring seat 10. The forming sleeve 4 is elastically connected to the sliding groove 3 through the matching of the spring seat 10 and the spring 11. When the first module 1 moves towards the second module 2 through the mutual matching of the first module 1 and the second module 2, the movement of the first module 1 will squeeze the forming sleeve 4 to move into the sliding groove 3. The movement of the forming sleeve 4 will squeeze the spring 11. At this time, the rotating plate 9 is squeezed, causing the roller 8 to slide in the sliding groove 6 and the moving groove 7. After the first module 1 and the second module 2 are closed, injection material is injected into the forming groove 5. After the wire spool is formed, the first module 1 and the second module 2 are slowly separated. At this time, the forming sleeve 4 is reset under the action of the spring 11, ensuring the stable movement of the forming sleeve 4, and further ensuring the quality of the finished plastic wire spool product. The forming groove 5 is a closed space, thereby making the finished plastic wire spool product beautiful.

[0027] One end of the spring 11 is fixedly connected to the spring seat 10, and the other end of the spring 11 is fixedly connected to the inner bottom surface of the sliding groove 3. The spring 11 is used for the stable movement of the forming sleeve 4.

[0028] A guide rod 12 is fixedly installed on the bottom surface of the first module 1.

At this time, the rotating plate 9 is squeezed, causing the roller 8 to slide in the sliding groove 6 and the moving groove 7. After the first module 1 and the second module 2 are closed, inject the injection material into the forming groove 5. After the wire spool is formed, slowly separate the first module 1 and the second module 2. At this time, the forming sleeve 4 returns to its original position under the action of the spring 11, and then the plastic wire spool product inside the forming groove 5 can be taken out. This solution is through the mutual matching of the first module 1 and the second module 2. When the first module 1 moves towards the second module 2, the movement of the first module 1 will squeeze the forming sleeve 4 to move into the sliding groove 3. When the forming sleeve 4 moves, it will squeeze the spring 11. At this time, the rotating plate 9 is squeezed, causing the roller 8 to slide in the sliding groove 6 and the moving groove 7. After the first module 1 and the second module 2 are closed, inject the injection material into the forming groove 5. After the wire spool is formed, slowly separate the first module 1 and the second module 2.
