Description

Technical Field

[0001] This utility model relates to the field of transformer core production technology, specifically to a mold bouncing mechanism for transformer core products. Background Technology

[0002] Transformer rubber core usually refers to the insulating rubber core part in the transformer frame or coil frame. It is a key component in the transformer used to support the coil, provide insulation and fix the winding structure.

[0003] This application improves upon existing technology. In existing technology, traditional transformer core molding dies typically consist of an upper die, a lower die, and a drive mechanism. The core is formed by pressing the upper and lower dies together. However, in the demolding process after molding, most existing dies rely on manual assistance or a single mechanical ejection structure. This is not only cumbersome and time-consuming, affecting production efficiency, but also prone to defects such as cracks and deformation in the core products due to uneven force during ejection, thus reducing the product qualification rate. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a mold spring mechanism for transformer core products, which solves the technical problem of inconvenient demolding in the prior art.

[0005] According to one aspect, at least one embodiment of the present invention provides a spring-loaded mechanism for a transformer core product mold, comprising a base plate, a lower mold fixedly connected to the base plate, an ejector plate provided inside the lower mold, symmetrically distributed uprights fixedly connected to the bottom of the ejector plate, the uprights being slidably connected to the lower mold, a first inclined surface being provided inside the uprights, symmetrically distributed L-shaped guide plates fixedly connected to the bottom outer wall of the lower mold, a movable column slidably connected to the L-shaped guide plate, the movable column being slidably connected to the lower mold, the movable column being fixedly connected to the ejector plate, a limit block fixedly connected to one end of the movable column extending out of the bottom of the L-shaped guide plate, a spring sleeved on the top of the limit block, and the other end of the spring being fixedly connected to the L-shaped guide plate.

[0006] For example, in a transformer core product mold bouncing mechanism provided in at least one embodiment of the present invention, there is also: an extrusion block is slidably connected to the inner wall of the upright, and a second inclined surface is provided on the side of the two extrusion blocks that are close to each other, and the second inclined surface is adapted to the first inclined surface.

[0007] For example, in a transformer core product mold bouncing mechanism provided in at least one embodiment of the present invention, there are also: symmetrically distributed support plates fixedly connected to the bottom of the base plate, a bidirectional screw rotatably connected between the two support plates, and the outer wall of the bidirectional screw is threadedly connected to the extrusion block.

[0008] For example, in a transformer core product mold bouncing mechanism provided in at least one embodiment of the present invention, a motor is fixedly connected to one of the support plates, and the output shaft of the motor is fixedly connected to a bidirectional screw.

[0009] For example, in a transformer core product mold bouncing mechanism provided in at least one embodiment of the present invention, the bottom of the base plate is provided with an installation groove, and the L-shaped guide plate is located in the installation groove.

[0010] For example, in a transformer core product mold bouncing mechanism provided in at least one embodiment of the present invention, a guide sleeve is fixedly connected to both inner walls of the mounting groove, a guide rod is slidably connected to the inner wall of the guide sleeve, and the guide rod is fixedly connected to the extrusion block.

[0011] For example, in a transformer core product mold bouncing mechanism provided in at least one embodiment of the present invention, the lower mold is provided with a receiving groove on the top, and the receiving groove is adapted to the ejector plate.

[0012] For example, in a transformer core product mold bouncing mechanism provided in at least one embodiment of the present invention, the following is further included: a fixed frame is fixedly connected to the top of the base plate, a cylinder is fixedly connected to the top of the fixed frame, and a movable plate is fixedly connected to the driving end of the cylinder.

[0013] For example, in at least one embodiment of the present invention, a transformer core product mold bouncing mechanism is provided, which further includes: an upper mold fixedly connected to the bottom of the movable plate, and the upper mold is located directly above the lower mold.

[0014] For example, in at least one embodiment of the present invention, a spring-loaded mechanism for a transformer core product mold is provided, which further includes: symmetrically distributed vertical rods on both sides of the movable plate, the vertical rods being fixedly connected to the base plate and the vertical rods being fixedly connected to the fixed frame, and a movable block being slidably connected to the outer wall of the vertical rods, and the movable block being fixedly connected to the movable plate.

[0015] The beneficial effects of the embodiments of this utility model are as follows: 1. In this utility model, when in use, the motor is started, and the output shaft of the motor rotates to drive the bidirectional screw to rotate. The bidirectional screw causes the two extrusion blocks to move closer to each other, and the extrusion blocks move and enter the upright. The upright moves down through the cooperation of the first inclined surface and the second inclined surface, which in turn drives the ejector plate to move down. The ejector plate enters the receiving groove, and the ejector plate causes the movable column and the limiting block to move. The spring is stretched. At this time, the driving end of the cylinder drives the movable plate to move down, so that the upper mold moves down and enters the lower mold for pressing and forming, thereby realizing the pressing and forming of the transformer core. 2. In this utility model, during demolding, the driving end of the cylinder drives the movable plate and the upper mold to move upward, causing the upper mold to separate from the lower mold. The output shaft of the motor rotates in the opposite direction, causing the bidirectional screw to rotate and drive the two extrusion blocks to move towards the side away from each other. The limiting effect of the extrusion blocks on the upright fails, the spring resets, causing the movable column and the ejector plate to reset. The ejector plate moves upward to eject the product, realizing demolding and improving production efficiency. Attached Figure Description

[0024] like Figures 1-5The diagram illustrates a spring-loaded mechanism for a transformer core product mold according to an embodiment of the present invention. It includes a base plate 1, a lower mold 2 fixedly connected to the base plate 1, an ejector plate 13 inside the lower mold 2, symmetrically distributed uprights 22 fixedly connected to the bottom of the ejector plate 13, and the uprights 22 slidably connected to the lower mold 2. A first inclined surface 23 is provided inside the uprights 22. Symmetrically distributed L-shaped guide plates 17 are fixedly connected to the bottom outer wall of the lower mold 2, and movable columns 1 are slidably connected to the L-shaped guide plates 17. 4. The movable column 14 is slidably connected to the lower mold 2, and the movable column 14 is fixedly connected to the ejector plate 13. One end of the movable column 14 extending out of the bottom of the L-shaped guide plate 17 is fixedly connected to a limit block 15. The top of the limit block 15 is fixedly connected to a spring 16 that is sleeved with the movable column 14, and the other end of the spring 16 is fixedly connected to the L-shaped guide plate 17. The ejector plate 13 and the movable column 14 can be reset after the spring 16 is reset, and the ejector plate 13 resets to eject the product, which is convenient for demolding.

[0025] In some examples, the inner wall of the upright 22 is slidably connected with a pressing block 21. The two pressing blocks 21 are provided with a second inclined surface 24 on the side that is close to each other, and the second inclined surface 24 is adapted to the first inclined surface 23. When the pressing block 21 moves into the upright 22 through the second inclined surface 24 and the first inclined surface 23, the pressing block 21 causes the upright 22 to move down, thereby driving the ejector plate 13 to move down.

[0026] The inclination angle between the first inclined plane 23 and the second inclined plane 24 is 30°-60°. This angle range ensures that the horizontal movement of the pressing block 21 can be efficiently converted into the vertical displacement of the upright rod 22, and avoids jamming during reset. The spring 16 is a tension spring, and its elastic coefficient satisfies that, under natural conditions, the spring force during reset can drive the ejector plate 13 to lift transformer core products with a weight of ≤500g.

[0027] In some examples, the bottom of the base plate 1 is fixedly connected to symmetrically distributed support plates 10, and a bidirectional screw 18 is rotatably connected between the two support plates 10. The outer wall of the bidirectional screw 18 is threadedly connected to the extrusion block 21. The bidirectional screw 18 facilitates the movement of the two extrusion blocks 21 toward either the side away from each other or the side closer to each other.

[0028] In some examples, a motor 11 is fixedly connected to one of the support plates 10. The output shaft of the motor 11 is fixedly connected to the bidirectional screw 18. The model of the motor 11 is 57BYG250H-0604. The motor 11 drives the bidirectional screw 18 to rotate.

[0029] In some examples, the bottom of the base plate 1 has a mounting groove 9, and the L-shaped guide plate 17 is located in the mounting groove 9.

[0030] In some examples, guide sleeves 19 are fixedly connected to the inner walls of both sides of the mounting groove 9. Guide rods 20 are slidably connected to the inner walls of the guide sleeves 19, and the guide rods 20 are fixedly connected to the extrusion block 21. The guide sleeves 19 and the guide rods 20 are set parallel to the bidirectional screw 18 to help limit the radial sway of the extrusion block 21 and prevent the extrusion block 21 from getting stuck due to tilt when it is engaged with the inclined surface of the upright 22. Together with the bidirectional screw 18, the extrusion block can achieve stable horizontal movement.

[0031] In some examples, the top of the lower mold 2 is provided with a receiving groove 12, and the receiving groove 12 is adapted to the ejector plate 13, so that the ejector plate 13 is accommodated by the receiving groove 12.

[0032] The depth of the receiving groove 12 is the same as the thickness of the ejector plate 13. After the ejector plate 13 is completely submerged in the receiving groove 12, its upper surface is flush with the bottom surface of the cavity of the lower mold 2, ensuring the molding accuracy of the core when the mold is closed.

[0033] In some examples, a fixed frame 3 is fixedly connected to the top of the base plate 1, a cylinder 4 is fixedly connected to the top of the fixed frame 3, and a movable plate 5 is fixedly connected to the drive end of the cylinder 4. The model of the cylinder 4 is SC50×75-S, and the movable plate 5 is driven to move up and down by the cylinder 4.

[0034] In some examples, the bottom of the movable plate 5 is fixedly connected to the upper mold 8, and the upper mold 8 is located directly above the lower mold 2. Pressing and forming are achieved through the upper mold 8 and the lower mold 2.

[0035] In some examples, the movable plate 5 has symmetrically distributed vertical rods 6 on both sides. The vertical rods 6 are fixedly connected to the base plate 1 and the fixed frame 3. The outer wall of the vertical rods 6 is slidably connected to the movable block 7, and the movable block 7 is fixedly connected to the movable plate 5. The vertical rods 6 guide the movement of the movable plate 5 and the movable block 7.

[0036] Working principle and usage process of this utility model: In this application, when in use, the motor 11 is started, and the output shaft of the motor 11 rotates, driving the bidirectional screw 18 to rotate. The bidirectional screw 18 causes the two extrusion blocks 21 to move closer to each other, and the extrusion blocks 21 move and enter the upright 22. Through the cooperation of the first inclined surface 23 and the second inclined surface 24, the upright 22 moves down, thereby driving the ejector plate 13 to move down. The ejector plate 13 enters the receiving groove 12, and the ejector plate 13 causes the movable column 14 and the limiting block 15 to move. The spring 16 is stretched. At this time, the driving end of the cylinder 4 drives the movable plate 5 to move down, causing the upper mold 8 to move down and enter the lower mold 2 for pressing and forming, thereby realizing the pressing and forming of the transformer core. In this application, during demolding, the driving end of the cylinder 4 drives the movable plate 5 and the upper mold 8 to move upward, causing the upper mold 8 to separate from the lower mold 2. The output shaft of the motor 11 rotates in the opposite direction, causing the bidirectional screw 18 to rotate and drive the two extrusion blocks 21 to move towards the side away from each other. The limiting of the extrusion block 21 on the upright rod 22 fails. The spring 16 resets, causing the movable column 14 and the ejector plate 13 to reset. The ejector plate 13 moves upward until the upper surface of the ejector plate 13 is 5-10mm higher than the bottom surface of the cavity of the lower mold 2, thus achieving demolding and improving production efficiency. In actual use, motor 11 and cylinder 4 are electrically connected to control panel via wires. Control panel controls cylinder 4 and motor 11. Control panel presets the following action logic: When the mold is closed, motor 11 first drives extrusion block 21 to close, causing ejector plate 13 to move down into receiving groove 12. After it is in place, cylinder 4 drives upper mold 8 to move down and close the mold. When the mold is demolded, cylinder 4 first drives upper mold 8 to move up until it is completely separated from lower mold 2. After it is in place, motor 11 drives extrusion block 21 to separate, causing ejector plate 13 to eject the product. Control panel is not shown in the figure.
