[0024] The vibration adjusting assembly 385 comprises a compression column 3851, a compression end of the compression column 3851 being communicated with a one-way electromagnetic valve 3852, the one-way electromagnetic valve 3852 being communicated with an expansion box 3853 through a pipeline, one side of the expansion box 3853 being fixedly connected to the inside of the side mold 2, the expansion box 3853 being slidably connected with a vibration rod 3854, the vibration rod 3854 being fixedly connected with the inside of the expansion box 3853 through a spring, the expansion box 3853 and the vibration rod 3854 being sealed through a sealing structure of the prior art, so that the vibration rod 3854 can normally slide, and the sealing effect of the expansion box 3853 is guaranteed. In the vibration adjusting assembly 385, the compression column 3851 cooperates with the compression ring 384 to provide compressed gas, which is transported into the expansion box 3853 provided with a spring in the inside after being controlled by the one-way electromagnetic valve 3852. When the gas pressure in the expansion box 3853 rises, the gas thrust will make the side of the expansion box 3853 limiting the vibration rod 3854 expand. In the initial state, the expansion box 3853 will compress the vibration rod 3854, at this time, the expansion box 3853 no longer compresses the vibration rod 3854, so that the spring is in an uncompressed state. When the moving block 383 reciprocates with the reciprocating sleeve 382, it will continuously collide with the vibration rod 3854, so as to make the vibration rod 3854 move to the inside of the expansion box 3853 and compress the spring connected thereto, at the same time, the vibration rod 3854 collides with the inner wall of the expansion box 3853 to generate a vibration force. Subsequently, under the action of the elastic force of the spring, the vibration rod 3854 will be reset in the opposite direction and collide with the inner wall of the expansion box 3853 again. Thus, the high-frequency vibration force is continuously generated, which effectively enhances the driving ability of the bubbles in the mixed material. When it is necessary to disassemble the side mold 2, the one-way electromagnetic valve 3852 can be opened to release the gas pressure in the expansion box 3853. At this time, the expansion end in the expansion box 3853 is reset and moves under the action of the spring connected thereto, and generates a compression force on the vibration rod 3854 and the spring connected thereto, so as to push the vibration rod 3854 away from the position of the mold body 1, that is, the distance between the vibration rod 3854 and the inside of the expansion box 3853 is relatively short. When the movable block 33 acts on the vibration rod 3854, since the spring is in a compressed state, the vibration rod 3854 will only collide with the inside of the expansion box 3853 after being impacted, which can reduce the adhesion between the side mold 2 and the mold body 1, thereby facilitating disassembly.

[0033] Working principle: when using the low-voltage transformer pouring mold assembly, first, the low-voltage transformer is installed in the mold body 1, then the side plate is inserted and installed with the mold body 1, during installation, by moving the side plate, the reciprocating screw sleeve 382 and the reciprocating screw 381 and the corresponding parts connected therewith are inserted into the inside of the side plate, after connection is completed, the mixed epoxy resin is injected into the cavity of the mold body 1 through the injection bucket, then the driving source is started, the driving source drives the belt pulley 373 to rotate through the synchronous rod 374, and then drives the transmission ring 372 to rotate, at this time, the plug-in ring 371 is pushed to keep plug-in with the transmission ring 372 through the damping spring, under the action of the rotation of the transmission ring 372, the plug-in ring 371 drives the transmission rod 31 to rotate synchronously, and the degassing vibration process is started; When the transmission rod 31 rotates, the pushing block 32 on the surface moves at the same time, continuously acts on the impact block 34 which is slidably connected in the movable block 33 in the cavity, makes the impact block 34 reciprocally slide in the sliding groove of the movable block 33, the impact block 34 and the transmission block 35 in the sliding groove form elastic collision through the spring, and reciprocally move under the force of the spring, generate high-frequency vibration, the vibration is directly transmitted to the mixed material in the mold body 1, loosens the bubbles wrapped therein, at the same time, the impact block 34 drives the fixed block 4 to reciprocally move through the movable rod, the fixed block 4 continuously collides with the vibration ring 5, makes the vibration ring 5 generate high-frequency vibration and expand the vibration coverage, accelerates the bubbles to escape to the top of the cavity or through the exhaust passage, in addition, the impact block 34 also drives the sliding plate 6 to reciprocally move, the friction vibration rod 7 in the inner side of the sliding plate 6 moves at the same time under the guidance of the support plate 9 and the guide plate 10 and continuously rubs with the fixed friction plate 8, generates high-frequency fine friction vibration, breaks the surface tension of the bubbles by means of the friction impact force, promotes the bubbles to break and cooperate with the vibration thrust to accelerate the floating, and the vibration of the impact block 34 forms complementation, improves the degassing efficiency; At the same time, the pushing block 32 on the transmission rod 31 also generates a pushing force on the top of the extrusion inclined block 362 during rotation, promotes the extrusion inclined block 362 to compress the gas in the gas storage box 361 through the gas pushing plate, the compressed gas pushes the moving plate to drive the impact ring 363 to slide, the impact ring 363 collides with the vibration block 364 at the bottom of the cavity to generate vibration force, the vibration force acts on the areas prone to bubble retention such as the small gap at the bottom of the cavity and the gap between the parts, effectively breaks the retained bubbles, and improves the degassing thoroughness, at the same time, the gas storage box 361 can be communicated with the expansion box 3853 through the one-way valve 13, when the gas pressure in the gas storage box 361 is insufficient, the compressed gas in the expansion box 3853 can be supplemented to the gas storage box 361 through the one-way valve 13, when the gas pressure in the expansion box 3853 is supplemented to the inside of the gas storage box 361, first, it is necessary to ensure that the gas pressure in the expansion box 3853 is sufficient, then the valve door connected with the one-way valve 13 of the expansion box 3853 can be opened, under the reciprocating action of the compression ring 384 driven by the reciprocating screw sleeve 382, in cooperation with the compression column 3851, the gas pressure in the expansion box 3853 can be supplemented; The transmission rod 31 also drives the reciprocating screw 381 to rotate when rotating, and the reciprocating screw 381 rotates to drive the reciprocating sleeve 382 and the compression ring 384 at the bottom to reciprocate in the communication groove of the side mold 2, the compression ring 384 reciprocates to cooperate with the compression column 3851 to provide compressed gas, the gas enters the expansion box 3853 through the one-way electromagnetic valve 3852, so that the expansion box 3853 expands, and no longer compresses the spring connected to the vibration rod 3854, at this time, the moving block 383 on the reciprocating sleeve 382 continues to collide with the vibration rod 3854 with reciprocating motion, so as to make the vibration rod 3854 move to the inside of the expansion box 3853 and compress the spring, and then reset in the opposite direction under the action of the spring force and collide again, continuously generating high-frequency vibration force, and enhancing the driving ability of the bubbles in the mixed material; When the side mold 2 needs to be disassembled, the electromagnetic block 377 is electrified to generate a magnetic repulsive force, which pushes the sliding ring 376 to move to the direction of the transmission ring 372 and inserts into the inside of the transmission ring 372, and at the same time pushes the plug-in ring 371 out of the transmission ring 372, so that the rotating power of the transmission ring 372 is only transmitted to the fixed rod 375 to drive the reciprocating screw 381 to rotate alone, at this time, the one-way electromagnetic valve 3852 is opened to release the air pressure in the expansion box 3853, the spring in the expansion box 3853 resets and pushes the spring connected to the vibration rod 3854 to the inside, and when the moving block 383 collides with the vibration rod 3854, only a single vibration is generated, which cooperates with the reciprocating motion of the reciprocating sleeve 382 to reduce the adhesion between the side mold 2 and the mold body 1, and improves the disassembly convenience, and the strong magnetic block 12 in the inside of the transmission ring 372 is magnetically connected with the inclined contact block 11 on the sliding ring 376, which can guide the sliding ring 376 to smoothly insert into the transmission ring 372, avoid jamming, and ensure the stability of the switching process; Through the cooperative operation of each component, the mold assembly can effectively remove the bubbles in the mixed material through multi-angle vibration during pouring to improve product quality, and can facilitate the separation of the side mold 2 through vibration adjustment during disassembly to improve production efficiency.
