[0030] Embodiment 1, reference Figure 1 Figure 2 For the first embodiment of the present application, a universal pouring mold for a mutual inductor is provided, which comprises: a support operation member 1 which plays a supporting role as a whole and cooperates with a moving unit 2 to drive during mold closing, and a mold unit 3 and a sliding groove 4 which ensure the stability of movement during mold pouring.

[0031] The support operation member 1 is provided with the moving unit 2 for mold closing driving of the mold unit 3; the moving unit 2 is provided with the mold unit 3 for mold pouring of the mutual inductor, and the mold unit 3 is slidingly connected with the support operation member 1, and the inner wall of the support operation member 1 is provided with the sliding groove 4 which can ensure the stable movement of the mold unit 3 during mold closing.

[0032] Further, the moving unit 2 comprises a driving assembly 21 fixedly installed on the support operation member 1 and a pushing assembly 22 fixedly installed on the driving assembly 21, the driving assembly 21 is used to drive the pushing assembly 22, and the pushing assembly 22 is slidingly connected with the support operation member 1, and the driving assembly 21 moves the pushing assembly 22 to realize mold closing.

[0033] Further, the mold unit 3 comprises a mold closing assembly 31 fixedly installed on the pushing assembly 22, the mold closing assembly 31 is internally provided with a cavity matched with the structure of the mutual inductor, the mutual inductor is placed inside the mold closing assembly 31 to be poured, the inner wall of the mold closing assembly 31 is provided with an exhaust assembly 32 which can exhaust the excess gas inside the mold closing assembly 31 after mold closing, and the installation assembly 33 rotatably connected on the support operation member 1 realizes the installation of the mutual inductor inside the mold closing assembly 31.

[0034] During use, first, when the mutual inductor is epoxy resin poured and plated, the mutual inductor is installed inside the installation assembly 33, then the driving assembly 21 starts to drive the pushing assembly 22, the pushing assembly 22 moves with the mold closing assembly 31 to the middle installation assembly 33 at the top of the support operation member 1, until the mold closing assemblies 31 on both sides are attached to the outer wall of the installation assembly 33, thereby completing mold closing, and the buckles 315 on the mold closing assembly 31 are also directly buckled into the clamping grooves 333 in the installation assembly 33, further strengthening the fixation of mold closing, then the pouring of materials into the mold closing assembly 31 is started, the mold closing assembly 31 guides the poured materials to flow to the bottom of the cavity inside the mold closing assembly 31, so that the poured materials start to spread uniformly from the bottom upwards for all-around wrapping pouring.

[0035] ​The epoxy resin material spreads upwards inside the mold assembly 31, and at the same time, the epoxy resin liquid extrudes the air inside the cavity of the mold assembly 31 upwards, so that the air inside the mold assembly 31 moves upwards and is discharged outside the mold assembly 31 through the exhaust assembly 32, ensuring the vacuum nature of the inside of the mold assembly 31, and when the pouring liquid contacts the exhaust assembly 32, the exhaust assembly 32 moves upwards, thereby plugging the exhaust assembly 32, so that a vacuum pouring space is formed inside the mold assembly 31, and the driving assembly 21 also rotates slightly, so that the pushing assembly 22 starts to impact the outer wall of the mold assembly 31, causing the mold assembly 31 to vibrate, ensuring the compactness of the pouring material inside the mold assembly 31, avoiding the generation of small bubbles during pouring, and ensuring the compactness and electrical performance of the product.

The top of the moving plate 217 is fixedly installed with a limiting plate 218, and the limiting plate 218 is in sliding connection with the support operation member 1, so that the stability of the movement of the limiting plate 218 is ensured when the moving plate 217 moves.

[0037] Further, compared with the first embodiment, the pushing assembly 22 comprises a moving member 221 fixedly installed on the moving plate 217, a connecting plate 223 fixedly installed on the moving member 221, the connecting plate 223 being used to connect a pushing member 224, and the pushing member 224 being fixedly installed on the connecting plate 223, and the pushing member 224 being in fixed connection with the mold assembly 31, so that the mold assembly 31 can be pushed to close when the pushing member 224 moves.

[0038] ​Further, the moving piece 221 is fixedly installed with a buffer piece 225, which can limit the moving piece 221, and the other end of the buffer piece 225 is fixedly installed with an impact plate 227 to impact the mold assembly 31, the outer wall of the buffer piece 225 is fixedly installed with a damping spring 226, and the damping spring 226 is connected with the impact plate 227 and the moving piece 221, and plays a buffering role when the impact plate 227 impacts, and the top of the moving piece 221 is fixedly installed with a limiting block 222, and the limiting block 222 is slidingly connected with the supporting operation piece 1, to ensure the stability of the moving piece 221 when moving.

[0039] In use, first, after the mutual inductor is installed on the installation assembly 33, the motor 211 starts to drive, the rotating ring 212 drives the two connecting rods one 213 to shrink to the middle, and at the same time, the rotating shaft one 214 also starts to shrink and adjust, drives the connecting rod two 215 to rotate and shrink with the rotating shaft two 216, so that the moving plate 217 drives the moving piece 221, and then the pushing piece 224 on the connecting plate 223 pushes the mold assembly 31 to move to the direction of the installation assembly 33. And at the same time that the moving piece 221 and the moving plate 217 move, the limiting plate 218 and the limiting block 222 also slide in the inside of the supporting operation piece 1, so as to ensure the stability of the moving piece 221 and the moving plate 217 when moving. After the motor 211 drives the pushing piece 224 to adhere the mold assembly 31 on the installation assembly 33, and the mold assembly 31 and the installation assembly 33 are fixed, pouring into the inside of the installation assembly 33 is started. At the same time of pouring, the motor 211 continues to rotate forward and reversely with small amplitude, so that the buffer piece 225 and the impact plate 227 on the moving piece 221 can constantly impact on the mold plate 311, so that the mold plate 311 and the mold piece 312 together vibrate at a uniform speed, to ensure the uniform distribution of the impact degree, so that the epoxy resin material poured in the inside of the mold assembly 31 is more compact, to ensure the pouring compactness during the pouring process of the mold assembly 31. And after the pouring is completed, the motor 211 reversely rotates, the moving piece 221 drives the pushing piece 224 and the mold assembly 31 to separate from the installation assembly 33, so as to perform the operation of opening the mold and discharging, and then improve the material adhesion, to achieve the effect of avoiding micro bubbles.
