Description

Technical Field

[0001] The invention relates to the technical field of current transformer production, and in particular to a current transformer casting mould. Background Art

[0002] A current transformer is an instrument that converts a large current on the primary side into a small current on the secondary side for measurement based on the principle of electromagnetic induction. It consists of a closed iron core and a winding. The primary winding has very few turns and is connected in series in the circuit of the current to be measured. The secondary winding has more turns and is connected to a measuring instrument or a protective device. When current passes through the primary winding, an alternating magnetic flux will be generated in the iron core, and this magnetic flux will pass through the secondary winding. According to the law of electromagnetic induction, an electromotive force will be induced in the secondary winding, thereby generating a secondary current. The ratio of the primary current to the secondary current is equal to the ratio of the number of turns of the secondary winding to the number of turns of the primary winding, which is the transformation ratio of the current transformer.

[0003] When the current transformer is being cast, it is easily affected by bubbles, so that many bubbles will be generated on the casting, affecting the quality of the current transformer, being unfavorable for subsequent use, and reducing the performance. Summary of the invention

At the same time, mesh plates are provided at both ends of the connecting pipe, so that the water in the water tank can be filtered to prevent the water in the water tank from mixing with foreign impurities, thereby clogging the connecting pipe and causing the connecting pipe to be blocked. At the same time, the water in the water tank is driven by the water pump to enter the connecting pipe. When the water flows through the inner cavity of the connecting pipe, it drives the cleaning mechanism to clean the inner wall of the connecting pipe, thereby preventing the water from cooling through the connecting pipe for a long time, which will leave a large amount of scale and impurities on the inner wall of the connecting pipe. At the same time, when the water continues to flow in the connecting pipe, the impact of the water flow drives the knocking mechanism to vibrate, thereby knocking and vibrating the inner side of the mold body, thereby removing bubbles in the casting material; Preferably, the knocking mechanism includes a connecting sleeve, the inner side of the connecting sleeve is rotatably connected to the side of the guide rod, the side of the connecting sleeve is fixedly connected to a connecting frame, the connecting frame is slidably connected to a knocking block on a side away from the connecting sleeve, a sliding rod is fixedly connected to the connecting frame, the side of the sliding rod is slidably connected to the inner side of the knocking block, a second spring is sleeved on the sliding rod, one end of the second spring is fixedly connected to the connecting frame, and the other end of the second spring is fixedly connected to the knocking block, and the inner wall of the connecting pipe is fixedly connected to a fixed block; when the stored water in the water tank is driven by the water pump, the water in the water tank flows in the inner cavity of the connecting pipe, thereby impacting the connecting frame, the connecting frame rotates on the guide rod through the connecting sleeve, and the connecting frame drives the knocking block to rotate and impact the fixed block, so that the vibration force generated when the knocking block collides with the fixed block causes the bubbles to float up and be discharged from the mold cavity, thereby eliminating the bubbles in the casting material. During the casting process, the air in the mold cavity needs to be discharged in time, otherwise bubbles will be formed inside the product, affecting the product quality.

Moreover, scale is a poor conductor of heat. As the scale layer thickens, the heat dissipation performance of the cooling pipe will be significantly reduced; Preferably, the buffer mechanism includes a buffer frame, the side surface of the buffer frame is fixedly connected to the inner side of the connecting pipe, the inner side of the buffer frame is fixedly connected to the side surface of the guide rod, a yield groove is opened in the middle of the buffer frame, a buffer block is fixedly connected to the side of the buffer frame close to the cleaning mechanism, a sliding rod is slidably connected to the inner side of the buffer block, a third spring is sleeved on the sliding rod, one end of the third spring is fixedly connected to the buffer plate, the other end of the third spring is fixedly connected to the inner side of the buffer frame, the end of the sliding rod away from the buffer block is fixedly connected to the buffer plate, and the side surface of the buffer plate is in contact with the inner side of the buffer block; when the water pump stops working, the impact force of the water flow passing through the connecting pipe is less than the reset stretching force of the first spring The first spring drives the cleaning plate to reset and move, so that the cleaning plate and the buffer frame collide and vibrate, and the scale and impurities attached to the scratch plate after cleaning and scratching are shaken off, so as to avoid a large amount of scale impurities remaining on the scratch plate and being difficult to fall off naturally. At the same time, by arranging a buffer block and a buffer plate on the buffer frame, when the cleaning plate collides with the buffer plate, the buffer plate performs buffering work. The material of the buffer plate is rubber material. The buffer plate works through the buffering stretching of the third spring. When the buffer plate and the cleaning plate reset and collide, the buffer plate performs buffering sliding on the inner side of the buffer frame, so as to avoid that the buffering force between the cleaning plate and the buffer frame is large when the cleaning plate is reset and moved, which will cause extrusion damage to the cleaning plate; Preferably, the blanking component comprises a support frame, the top of the support frame is fixedly connected to the bottom of the casting component, the top of the support frame is provided with a blanking port, the inner side of the support frame is fixedly connected to a collecting frame, the top of the collecting frame is slidably connected to a moving rod, a fourth spring is sleeved on the moving rod, one end of the fourth spring is fixedly connected to the arc plate, the other end of the fourth spring is fixedly connected to the inner side of the collecting frame, one end of the moving rod away from the collecting frame is fixedly connected to the arc plate, and the side of the arc plate is evenly provided with circular holes, the side of the collecting frame is fixedly connected to a motor, the output end of the motor is fixedly connected to one end of the rotating rod, the bottom of the inner cavity of the collecting frame is fixedly connected to a suction mechanism, the inner side of the collecting frame is rotatably connected to a rotating rod, the side of the rotating rod is fixedly connected to a bent plate, and the side of the rotating rod away from the bent plate is fixedly connected to a contact plate; when the casting material is completely solidified, the output end of the electric hydraulic cylinder drives the two mold bodies to move in opposite directions, so that the casting falls on the arc plate through the blanking port, and the material of the arc plate is rubber The casting is made of plastic. When the casting collides with the arc plate after demoulding and falling, the arc plate is subjected to extrusion force and moves in the support frame through the moving rod.

At the same time, when collecting the casting, the suction mechanism is opened and the suction mechanism is used to perform suction work, so that when the suction mechanism collides with the arc plate, the impurities and The burrs are adsorbed and enter the inner cavity of the collecting rack through the circular holes on the arc plate. At the same time, when the collection work is carried out, the motor is turned on, and the output end of the motor drives the rotating rod to rotate in the inner cavity of the collecting rack, so that the rotating rod drives the bent plate and the contact plate to rotate in the inner cavity of the collecting rack. By opening a square groove on the side of the contact plate, when the contact plate is rotated by the rotating rod, the flocculent dust entering the inner cavity of the collecting rack can be grabbed and rotated, thereby preventing the flocculent dust entering the collecting rack from adhering to the casting.

[0005] The beneficial effects of the present invention are as follows: 1. The present invention sets a casting component, turns on the electric hydraulic cylinder, and drives the two mold bodies to move relative to each other through the output end of the electric hydraulic cylinder. When the two mold bodies are accurately matched together, casting material is added to the pouring port, and at the same time, the water in the water tank is turned on through the connecting mechanism to enter the mold body, thereby cooling and molding the casting in the mold after casting.

[0006] 2. The present invention provides a connecting mechanism, and uses a water pump to pump the stored water in the water tank into the connecting pipe. The stored water in the water tank flows through the top of the connecting pipe to the water tank at the bottom of the connecting pipe, thereby cooling the temperature in the mold body. At the same time, mesh plates are provided at both ends of the connecting pipe, so that the stored water in the water tank can be filtered to prevent the stored water in the water tank from mixing with external impurities, thereby clogging the connecting pipe and causing the connection pipe to be blocked. At the same time, the stored water in the water tank enters the connecting pipe through the drive of the water pump. When the water flows through the inner cavity of the connecting pipe, it also drives the cleaning mechanism to clean the inner wall of the connecting pipe, thereby avoiding the water flow passing through the connecting pipe for a long time for cooling, which will leave a large amount of scale and impurities on the inner wall of the connecting pipe. At the same time, when the water flow continues to flow in the connecting pipe, the impact of the water flow drives the knocking mechanism to vibrate, thereby knocking and vibrating the inner side of the mold body, thereby removing bubbles in the casting material.

[0007] 3. The present invention sets a knocking mechanism. When the water stored in the water tank is driven by a water pump, the water in the water tank flows in the inner cavity of the connecting pipe, thereby impacting the connecting frame. The connecting frame is rotated on the guide rod through the connecting sleeve. The connecting frame drives the knocking block to rotate and impact the fixed block. The vibration force generated when the knocking block collides with the fixed block causes the bubbles to float up and be discharged from the mold cavity, thereby eliminating the bubbles in the casting material.

[0008] 4. The present invention provides a cleaning mechanism. When the water stored in the water tank is pumped by a water pump to flow in the connecting pipe, the impact of the water flow causes the cleaning plate to slide on the guide rod through the through hole, so that the cleaning plate drives the scratching plate to clean the inner wall of the connecting pipe, thereby avoiding a large amount of scale remaining on the inner wall of the connecting pipe when the water flows through the connecting pipe for a long time, reducing the inner diameter of the cooling pipe, affecting the water flow rate and heat exchange efficiency. Moreover, scale is a poor conductor of heat. As the scale layer thickens, the heat dissipation performance of the cooling pipe will be significantly reduced. BRIEF DESCRIPTION OF THE DRAWINGS

By turning on the electric hydraulic cylinder 22, the two mold bodies 23 are driven to move relative to each other through the output end of the electric hydraulic cylinder 22. When the two mold bodies 23 are accurately matched together, pouring material is added to the pouring port 4, and at the same time, by turning on the water pump 26, the water in the water tank 27 enters the mold body 23 through the connecting mechanism 24, so as to cool and shape the pouring part in the mold after pouring; The water in the water tank 27 is pumped into the connecting pipe 241 by the water pump 26. The water in the water tank 27 flows through the top of the connecting pipe 241 to the bottom of the connecting pipe 241, thereby cooling the temperature in the mold body. At the same time, mesh plates 242 are provided at both ends of the connecting pipe 241, so that the water in the water tank 27 can be filtered to prevent the water in the water tank 27 from mixing with foreign impurities, thereby clogging the connecting pipe 241 and causing the connecting pipe 241 to be blocked. At the same time, the water in the water tank 27 is filtered. The water pump 26 drives the water into the connecting pipe 241. When the water flows through the inner cavity of the connecting pipe 241, the cleaning mechanism 248 is driven to clean the inner wall of the connecting pipe 241, thereby preventing the water from cooling through the connecting pipe 241 for a long time, which will leave a large amount of scale and impurities on the inner wall of the connecting pipe 241. At the same time, when the water continues to flow in the connecting pipe 241, the impact of the water flow drives the knocking mechanism 247 to vibrate, thereby knocking and vibrating the inner side of the mold body, thereby removing bubbles in the casting material. When the water in the water tank 27 is driven by the water pump 26, the water in the water tank 27 flows in the inner cavity of the connecting pipe 241, thereby impacting the connecting frame 2472, and the connecting frame 2472 rotates on the guide rod 243 through the connecting sleeve 2471, and the connecting frame 2472 drives the knocking block 2473 to rotate and impact the fixed block 2476, so that the vibration force generated when the knocking block 2473 hits the fixed block 2476 makes the bubbles float up and discharge from the mold cavity, thereby eliminating the bubbles in the casting material. During the casting process, the air in the mold cavity needs to be discharged in time, otherwise bubbles will be formed inside the product, affecting the product quality; When the water stored in the water tank 27 is pumped by the water pump 26 to flow in the connecting pipe 241, the impact of the water flow causes the cleaning plate 2481 to slide on the guide rod 243 through the through hole 2482, so that the cleaning plate 2481 drives the scratching plate 2483 to clean the inner wall of the connecting pipe 241, thereby preventing a large amount of scale from remaining on the inner wall of the connecting pipe 241 when the water flows through the connecting pipe 241 for a long time, which will reduce the inner diameter of the cooling pipe and affect the water flow and heat exchange efficiency. In addition, scale is a poor conductor of heat. As the scale layer thickens, the heat dissipation performance of the cooling pipe will be significantly reduced. When the water pump 26 stops working, the impact force of the water flow in the connecting pipe 241 is less than the reset stretch of the first spring 246, and the first spring 246 drives the cleaning plate 2481 to reset and move, so that the cleaning plate 2481 and the buffer frame 2451 collide and vibrate, and the scale and impurities attached to the scratch plate 2483 after cleaning and scratching are shaken off, thereby avoiding a large amount of scale impurities from remaining on the scratch plate 2483 and being difficult to fall off naturally. At the same time, by arranging the buffer block 2453 and the buffer plate 2455 on the buffer frame 2451, the cleaning When the plate 2481 collides with the buffer plate 2455, the buffer plate 2455 performs buffering work. The material of the buffer plate 2455 is rubber. The buffer plate 2455 performs buffering stretching work through the third spring 2456. When the buffer plate 2455 and the cleaning plate 2481 perform reset collision, the buffer plate 2455 performs buffering sliding inside the buffer frame 2451, thereby preventing the cleaning plate 2481 from having a large buffering force with the buffer frame 2451 when performing reset movement, thereby causing squeezing damage to the cleaning plate 2481. When the casting material is completely solidified, the output end of the electric hydraulic cylinder 22 drives the two mold bodies 23 to move in the opposite direction, so that the casting falls on the arc plate 38 through the discharge port 32. At the same time, the material of the arc plate 38 is rubber. When the casting collides with the arc plate 38 after demoulding and falling, the arc plate 38 is subjected to extrusion force and moves in the support frame 31 through the moving rod 34. At the same time, the fourth spring 35 works as a buffer to avoid excessive impact force between the casting and the arc plate 38 when collecting the casting, thereby causing extrusion damage to the casting. At the same time, when collecting the casting, the suction mechanism 39 is opened and the suction mechanism 39 is used to perform suction work, so that When the suction mechanism 39 collides the casting with the arc plate 38, the impurities and burrs shaken off the surface of the casting are absorbed and enter the inner cavity of the collecting rack 33 through the round holes on the arc plate 38. At the same time, when the collection work is performed, by turning on the motor 37, the output end of the motor 37 drives the rotating rod 310 to rotate in the inner cavity of the collecting rack 33, so that the rotating rod 310 drives the bent plate 311 and the contact plate 36 to rotate in the inner cavity of the collecting rack 33. By opening a square groove on the side of the contact plate 36, when the contact plate 36 is rotated by the rotating rod 310, it can grab and rotate the flocculent dust entering the inner cavity of the collecting rack 33, thereby preventing the flocculent dust entering the collecting rack 33 from adhering to the casting.
