In this embodiment, the number of the mold bodies 1 and the adjustment plates 2 is two respectively, and the two mold bodies 1 are arranged opposite to each other, and the top and bottom of the two mold bodies 1 are respectively locked and connected by the adjustment plates 2, and the front and rear sides of each adjustment plate 2 are respectively provided with the intermediate blocks 5, and the left and right ends of the intermediate blocks 5 are respectively provided with the mounting posts 51, and each mounting post 51 is installed with the elastic member 4, that is, each adjustment plate 2 is provided with four mounting posts 51, and each adjustment plate 2 is installed with four elastic members 4, the elastic member 4 is a spring, and the top and bottom of each mold body 1 are respectively provided with two sliding grooves 11. During installation, the distance between the two mold bodies 1 is adjusted according to the required size of winding, specifically, the two mold bodies 1 are respectively moved left and right along the length direction of the two ends of the adjustment plate 2, and the mounting post 51 slides left and right in the sliding groove 11, one end of the elastic member 4 is against the inner wall of the mounting post 51, and the other end of the elastic member 4 is against the inner wall of the sliding groove 11, and the elastic member 4 is always in In the compressed state, after adjusting the distance between the two mold bodies 1, the locking assembly 3 is used to lock the left and right ends of the adjustment plate 2 to the two mold bodies 1 respectively. Preferably, the end of each adjustment plate 2 is locked and fixed to the mold body 1 through two groups of locking assemblies 3. It should be noted that the elastic force of the elastic member 4 is less than the locking force of the locking assembly 3. After locking and fixing, the wire is wound along the outer periphery of the winding mold formed by the combination of the two mold bodies 1; this application is through the mold body 1, sliding groove 11, adjustment plate 2, locking assembly 3, elastic Parts 4, intermediate blocks 5 and mounting posts 51 allow the two mold bodies 1 to move and adjust the distance between them, and can wind transformer coils of different sizes, thereby improving the versatility of the winding mold.

Even if part of the locking assembly 3 is loose, the wound coil is always in a tensioned state under the action of the elastic force, preventing the two mold bodies 1 from approaching each other during the winding process and causing the winding to become loose.

[0027] like Figure 2 and Figure 4-5As shown, the mold body 1 is provided with a mounting groove 12, and the inner side wall of the mounting groove 12 is provided with a guide groove 121. The adjustment plate 2 can be installed in the mounting groove 12 movably left and right. The outer side wall of the adjustment plate 2 is provided with a guide bar 21, and the guide bar 21 is slidably installed in the guide groove 121. In this embodiment, the top and bottom of the mold body 1 are respectively provided with the mounting grooves 12, and the end of the adjustment plate 2 can be movably installed in the mounting groove 12 movably left and right, and the guide grooves 121 are provided on the inner walls on the front and rear sides of the mounting groove 12, and the guide bars 21 are provided on the outer walls on the front and rear sides of the end of the adjustment plate 2. The guide bars 21 are slidably installed in the guide grooves 121, which not only allows the adjustment plate 2 to move smoothly, but also prevents it from moving out of position.

[0028] like Figure 2 and Figure 4 As shown, the mounting groove 12 is provided with a limiting groove 122, and the adjustment plate 2 is provided with a limiting block 22. The limiting block 22 is located in the limiting groove 122 and can move left and right along the length direction of the limiting groove 122.

During installation, the limiting blocks 22 are placed in the limiting grooves 122. When the mold body 1 and the adjustment plate 2 are relatively moved and adjusted, the limiting blocks 22 move left and right in the limiting grooves 122. The limiting grooves 122 and the limiting blocks 22 cooperate to play a limiting role, preventing the adjustment plate 2 from falling out of the mounting groove 12 under the elastic force of the elastic member 4 during the adjustment process.

[0029] like Figure 2-4As shown, the mounting groove 12 is provided with a threaded hole 123, the adjustment plate 2 is provided with an adjustment groove 23, the adjustment groove 23 is opposite to the threaded hole 123, and the adjustment groove 23 is provided with a tightening step 231; the locking assembly 3 includes a locking member 31, one end of the locking member 31 is installed in the threaded hole 123, and the other end of the locking member 31 is against the tightening step 231. When the cam 23 is tightened, the locking member 31 is tightened and the screw thread 231 is tightened, so that the cam 23 is tightened and the screw thread 231 is tightened.

[0030] like Figure 2-4 As shown, the locking assembly 3 further includes a rubber gasket 32; the pressing step 231 is provided with anti-slip grooves, and the rubber gasket 32 ​​is mounted on the locking member 31, with one side of the rubber gasket 32 ​​abutting against the anti-slip grooves, and the other end of the rubber gasket 32 ​​abutting against the head of the locking member 31. In this embodiment, the anti-slip grooves are provided on the top surface of the pressing step 231, and the rubber gasket 32 ​​is provided between the head of the locking member 31 and the pressing step 231. After locking, the head of the locking member 31 presses the rubber gasket 2 against the anti-slip grooves through the cooperation between the anti-slip grooves and the rubber gasket 32. The softness of the rubber gasket 2 and the friction generated by the pressing prevent the locking member 31 from slipping left and right in the adjustment slot 23, thereby improving the locking quality of the locking assembly 3.
