Technical Field

[0001] The invention relates to the technical field of mutual inductor casting, and in particular to a casting material pipe positioning and distributing device for manufacturing mutual inductors. Background Art

[0002] A transformer is a special transformer, which is mainly used to measure high voltage and high current, and convert high voltage and high current into low voltage and low current, so as to facilitate the use of measuring instruments, protection devices and other equipment, and ensure the safety of operators. Transformers are divided into current transformers and voltage transformers. Current transformers are used to measure high currents and convert them into low currents; voltage transformers are used to measure high voltages and convert them into low voltages. Transformers have the advantages of high precision, strong reliability, small size and light weight, and are widely used in power systems, industrial automation and other fields. During the production of mutual inductors, the coils and iron cores need to be insulated. Usually, the iron core and the coil are placed in a mold, and then the insulating material is injected into the mold to wrap the iron core and the coil to improve the insulation performance and mechanical strength of the mutual inductor. Commonly used casting materials are epoxy resin, polyurethane, etc. After casting, curing and post-processing are required to ensure the performance and reliability of the mutual inductor. During casting, the mold needs to be positioned and the casting material needs to be laid. Therefore, we proposed a casting material pipe positioning and laying equipment for mutual inductor manufacturing. Summary of the invention

Under the vacuum negative pressure, the sealing plate is sucked and better adheres to the top of the mold to achieve better sealing, and then the casting material is injected from the inside of the connecting tube, and the casting material is spread to the inner side of the mold through the cloth assembly, and During the filling process, it gradually converges to the center and finally covers the iron core, leaving a casting margin to compensate for the shrinkage of the material after curing. When sealing, the sealing plate is flattened at the top of the mold, and the outermost side is covered on the outer side of the top of the mold, so as to locate the casting position. The sealing plate with a corrugated structure can change its own circular area and can seal molds of different diameters to provide sealing conditions for casting. The umbrella-shaped structure of the driving component can drive the sealing plate to unfold evenly, ensure the uniform flattening of the sealing plate, and ensure that the sealing plate can evenly cover the outer side of the top of the mold to avoid gaps and affect the vacuum effect. The cloth component makes the raw materials converge from the inner side of the mold to the center, and presses into the gap between the iron core and the coil from the outermost side under vacuum pressure. Then it covers the iron core to retain the processing margin. As the castable is filled, the negative pressure inside the mold will gradually disappear. Filling the gap first can ensure that the gap is completely filled before the negative pressure is eliminated, avoiding gaps or bubbles in the product.

[0004] Furthermore, a limiting groove is provided on the outer side surface of the connecting tube, and the limiting groove is set to be trapezoidal, and there are several limiting grooves evenly distributed along the circumference of the connecting tube, and the inner sides of several limiting grooves are slidably connected to the limiting plate, and the side of the limiting plate away from the axis of the connecting tube is threadedly connected to the inner side surface of the sleeve, and the end of the limiting plate away from the driving component is fixedly connected to the side of the cloth component close to the sealing plate, and the connecting tube slides inside the sleeve to drive the driving component to flatten the sealing plate, and by setting the limiting groove and the limiting plate that are slidably adapted, the sliding of the connecting tube and the sleeve can be limited to avoid distortion of the sealing plate and affect the sealing effect, and the connecting tube can slide out of the sleeve, which can facilitate the removal and cleaning of the connecting tube, and under the tension of the elastic force of the sealing plate, the connecting tube can be prevented from sliding out at will.

As the castable is filled, the vacuum negative pressure disappears, and the removal of the sealing plate will not be affected by the negative pressure. While cooperating with the vacuum environment for better sealing, it is convenient to remove the product after curing, and it is convenient to realize continuous processing. The umbrella-shaped distribution of the rod body can evenly unfold the sealing plate to avoid wrinkles when the sealing plate is unfolded, and avoid affecting the sealing effect of the sealing plate.

A circular plate 334 is set, and the motor 335 is placed in the gap between the circular plate 334 and the cloth plate 331, which can separate the motor 335 from the castable material, and prevent the castable material from entering the motor 335 and affecting the operation of the motor 335. At the same time, the heat generated by the operation of the motor 335 set in the gap is transferred to the cloth plate 331, and the heat is transferred to the raw materials flowing on the surface of the cloth plate 331, which can have a certain insulation effect on the raw materials.

[0030] A connecting plate 336 is provided at the interval between the circular plate 334 and the cloth plate 331. A plurality of connecting plates 336 are provided along the circumference of the circular plate 334. The connecting plate 336 is fixedly connected to the side of the circular plate 334 close to the motor 335. The end of the connecting plate 336 away from the circular plate 334 is fixedly connected to the surface of the motor 335. The connecting plate 336 is provided to further fix the motor 335 to avoid large vibrations and noises during the operation of the motor 335.

[0031] The surface of the rotating shaft 332 is rotatably connected with an isolation sleeve 337, the end surface of the isolation sleeve 337 is fixedly connected to the side of the cloth plate 331 away from the circular plate 334, and the inner side surface of the isolation sleeve 337 is arranged in a stepped shape, the inner side surface of the isolation sleeve 337 and the surface of the rotating shaft 332 are rotationally limited, and the isolation sleeve 337 is arranged to block the position where the rotating shaft 332 passes through the cloth plate 331 to prevent the casting material from entering its gap, thereby ensuring that the rotation of the rotating shaft 332 is not affected, and the inner side surface of the isolation sleeve 337 is stepped, and the stepped inner side surface can form multiple seals, which can prevent the casting material from entering the gap between the isolation sleeve 337 and the rotating shaft 332 to the greatest extent, thereby further maintaining the rotation of the rotating shaft 332.

[0032] When in use, the connecting tube 2 is pressed, and the connecting tube 2 slides inside the sleeve 1, driving the fixing ring 321 to descend, thereby driving the rod body 322 hinged therewith to gradually become horizontal, driving the ring body 323 to move, and finally driving the sealing plate 31 to flatten, and the sealing plate 31 to unfold, driving the slider 325 to slide on the surface of the sliding rod 324, and causing a small axial deflection, the slider 325 deflects, driving the sliding rod 324 to deform slightly, and after flattening, the rod body 322 abuts against the top of the mold through the sealing plate 31, and the connecting tube 2 continues to move, driving the rod body 322 to deform at the abutting position, and then the sealing plate 31 covers the outer side surface of the mold, and Under the elastic force of the contraction of the sealing plate 31, the top of the mold can be sealed, and the mold can be evacuated from other positions of the mold. Under the vacuum negative pressure, the sealing plate 31 is sucked and better adheres to the top of the mold to achieve better sealing. Then, the casting material is injected from the inside of the connecting pipe 2. The casting material passes through the connecting pipe 2 and reaches the conical surface of the distribution plate 331, flows along the conical surface of the distribution plate 331, and finally enters the mold. While pouring, the motor 335 is started, and the output end of the motor 335 drives the rotating shaft 332 to rotate, drives the stirring blade 333 to rotate, stirs the injected casting material, and finally completes the pouring.
