A diode pin forming die

Abstract

This utility model relates to the field of diode forming technology and discloses a diode lead forming mold, including a base. Limiting components are fixedly connected to both sides of the base. Three sets of slide bars are slidably connected inside the base. A lower mold is fixedly connected to the top surface of the three sets of slide bars. A clamping component is slidably connected inside the lower mold. This diode lead forming mold, through the clamping component, allows the diode to be placed inside the lower mold during use. Activating a servo motor causes a bidirectional lead screw to rotate, which in turn moves a clamping plate along the lead screw.

This ensures precise positioning of the diode during the forming process and improves lead forming accuracy.

Description

Technical Field

[0001] This utility model relates to the field of diode forming technology, and in particular to a mold for forming diode leads. Background Technology

[0002] To manufacture a diode, the chip is soldered into a lead frame with pre-set pathways. The frame and chip are then placed into an injection mold. A fluid insulating material is injected into the mold using an injection molding machine. After the insulating material cools and solidifies, the diode is demolded and cut to obtain an independent semi-finished diode. Finally, the leads are bent to complete the production process.

[0003] A diode lead forming mold disclosed in publication CN210334121U includes an upper mold plate, an upper die, a lower mold, and a lower template arranged sequentially. The upper mold includes two first pressing blocks, and the top of the lower mold has two spaced-apart lead support plates. The projection of the first pressing blocks onto the lower mold is a first projection, and the two first projections are located on the side of the two lead support plates away from the center of the lower mold, with a gap between the first projections and the lead support plates. This invention provides lead support plates at the bottom of the leads for close contact and support. During mold closing and bending forming, the lead support plates can effectively counteract the bending force transmitted to the plastic body, reduce the tendency for relative displacement between the leads and the plastic body, effectively prevent the plastic body from tearing, and thus ensure the reliability of the bending action.

[0004] While the aforementioned patent effectively prevents the plastic body from tearing, thus ensuring the reliability of the bending action, the device, when used, places the diode directly on it. During bending, the diode may become misaligned, resulting in different bending lengths for the leads on both sides. Additionally, the diode may shift during bending, affecting the quality of the diode processing. Utility Model Content

[0005] The purpose of this invention is to provide a die for forming diode leads, which solves the problem mentioned in the background art that when the device is used, the diode is placed directly on the device, and when the diode is bent, it will not be centered, resulting in different bending lengths on both sides of the diode. At the same time, the diode will also move during bending, thus affecting the quality of diode processing.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a diode pin forming mold, comprising a base, with limiting components fixedly connected to both sides of the base, three sets of slide bars slidably connected inside the base, a lower mold fixedly connected to the top surface of the three sets of slide bars, and a clamping assembly slidably connected inside the lower mold. The limiting components include two sets of limiting hydraulic rods fixedly connected to both sides of the base, with a limiting plate fixedly connected to one end of each of the two sets of limiting hydraulic rods, and two sets of guide rods slidably connected inside each of the two sets of limiting plates. The clamping assembly includes two sets of clamping plates slidably connected inside the lower mold, with a bidirectional lead screw threadedly connected to the inside of each of the two sets of clamping plates, and a servo motor fixedly connected to one end of the bidirectional lead screw.

[0007] As a further embodiment of this utility model, two sets of buffer strips are fixedly connected to the top surface of the lower mold, and a placement cavity is opened inside the lower mold. The buffer strips reduce the impact force generated during the use of the device.

[0008] As a further embodiment of this utility model, a mounting box is fixedly connected to one side of the lower mold, and a motor housing is fixedly connected to one side of the mounting box. The motor housing serves to store the servo motor.

[0009] As a further embodiment of this utility model, four sets of support rods are fixedly connected to the top surface of the base, and one end of each set of support rods is fixedly connected to a top plate. The support rods provide support for the top plate.

[0010] As a further embodiment of this utility model, a lifting hydraulic rod is fixedly connected to the top surface of the top plate, and a lower pressure plate is fixedly connected to one end of the lifting hydraulic rod. The lifting hydraulic rod serves to drive the lower pressure plate to move.

[0011] As a further embodiment of this utility model, two sets of telescopic rods are fixedly connected to the top surface of the lower pressure plate, and bending plates are fixedly connected to both sides of the lower pressure plate. The bending plates serve to bend the diode pins.

[0012] As a further embodiment of this utility model, the interior of both sets of clamping plates is slidably connected with limit rods, and the surface of the base is provided with three sets of slide rails, with the three sets of slide bars slidably connected inside the slide rails. The setting of the limit rods makes the clamping plates move more smoothly.

[0013] (III) Beneficial Effects This utility model provides a die for forming diode leads, which has the following advantages: 1. This diode lead forming mold, through the clamping assembly, allows the diode to be placed inside the lower mold during use. Activating the servo motor drives a bidirectional lead screw, which in turn moves the clamping plate along the screw, firmly holding the diode and preventing movement or displacement during lead forming. This ensures precise diode positioning and improves lead forming accuracy. 2. The diode lead forming mold, through the use of a slide bar and limiting assembly, prevents wear or damage to the lower mold during long-term use, which could affect forming quality. Activating the limiting hydraulic rod moves a limiting plate, pulling it out of the lower mold. After extraction, the lower mold is moved to separate from the base, allowing for easy replacement and preventing wear or damage to the lower mold from affecting forming quality.

[0017] Please see Figures 1 to 4This utility model provides a technical solution: a diode pin forming mold, including a base 1, with limiting components 2 fixedly connected to both sides of the base 1. The limiting components 2 fix the lower mold 4, allowing the lower mold 4 to be replaced. Three sets of slide bars 3 are slidably connected inside the base 1, and the lower mold 4 is fixedly connected to the top surface of the three sets of slide bars 3. A clamping component 5 is slidably connected inside the lower mold 4, clamping the diode. The limiting components 2 include two sets of limiting hydraulic rods 201 fixedly connected to both sides of the base 1. One end of each of the two sets of limiting hydraulic rods 201 is fixedly connected to a limiting plate 202, and two sets of guide rods 203 are slidably connected inside each of the two sets of limiting plates 202. The clamping component 5 includes two sets of clamping plates 501 slidably connected inside the lower mold 4. A bidirectional lead screw 502 is threadedly connected inside the two sets of clamping plates 501, and a servo motor 503 is fixedly connected to one end of the bidirectional lead screw 502. Two sets of buffer strips 6 are fixedly connected to the top surface of the lower mold 4. The interior of the lower mold 4 is provided with a placement cavity. The buffer strips 6 are designed to reduce the impact force generated during the use of the device. A mounting box 7 is fixedly connected to one side of the lower mold 4, and a motor box 8 is fixedly connected to one side of the mounting box 7. The motor box 8 serves to store the servo motor 503. Four sets of support rods 9 are fixedly connected to the top surface of the base 1. One end of each set of support rods 9 is fixedly connected to the top plate 10. The support rods 9 serve to support the top plate 10. A lifting hydraulic rod 11 is fixedly connected to the top surface of the top plate 10. One end of the lifting hydraulic rod 11 is fixedly connected to a lower pressure plate 12. The lifting hydraulic rod 11 serves to drive the lower pressure plate 12 to move. Two sets of telescopic rods 13 are fixedly connected to the top surface of the lower pressure plate 12, and bending plates 14 are fixedly connected to both sides of the lower pressure plate 12. The bending plates 14 are used to bend the diode pins. Both sets of clamping plates 501 are slidably connected to limit rods 15 inside.

The setting of the limit rods 15 makes the clamping plates 501 move more smoothly.

[0018] In this invention, the working steps of the device are as follows: First step: When using the diode, place it inside the lower mold 4, start the servo motor 503, the servo motor 503 rotates and drives the bidirectional lead screw 502 to rotate. The rotation of the bidirectional lead screw 502 causes the clamping plate 501 to move on the bidirectional lead screw 502. The movement of the clamping plate 501 clamps the diode, which can firmly fix the diode body and prevent the diode body from moving or displacing during the lead forming process. This can ensure the accurate position of the diode during the forming process and improve the accuracy of lead forming. The second step: During long-term use, the lower mold 4 may experience wear or damage, affecting the molding quality. In this case, the limiting hydraulic rod 201 is activated, pushing the limiting plate 202 to move. The limiting plate 202 is then pulled out from inside the lower mold 4. After extraction, the lower mold 4 is moved to separate from the base 1, allowing for replacement of the lower mold 4 and preventing wear or damage from affecting the molding quality.
