Description

Technical Field

[0001] This utility model relates to the field of mold device technology, and in particular to a connector terminal forming mold. Background Technology

[0002] Terminals are key components used to achieve electrical connections. They are made of conductive metal and their surfaces are electroplated to enhance conductivity and corrosion resistance. They come in various shapes, including pin, plate, and fork types. They can be connected to wires, circuit boards, and other terminals through crimping, soldering, or plugging. They are widely used in the fields of electronics, automobiles, and communications. In circuit systems, they play the roles of current transmission, signal connection, and mechanical fixation, and are fundamental components that ensure the stable operation of equipment.

[0003] After the terminals are stamped, workers use sandpaper to polish them to remove the oxide layer on their surface. However, manual polishing relies on the manual actions of individual operators and needs to be processed one by one, which is slow, especially for terminals with complex structures. Existing technology uses electrolysis to dissolve the microscopic protrusions on the terminal surface to remove the oxide layer and polish it. However, electrolyte will remain on the surface of the polished terminals. If the cleaning is not thorough, it will cause corrosion. It is necessary to rinse with pure water in multiple stages and dry it, which increases water and energy consumption and raises production costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a connector terminal forming mold, which aims to improve the problem that the existing technology of using electrolytic solution to polish terminals requires multiple stages of rinsing and drying with pure water, which increases water and energy consumption and raises production costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a connector terminal forming mold, comprising a machine tool, a grinding mechanism fixedly connected to the left end of the outer wall of the machine tool, the grinding mechanism being used to grind the stamped and plasticized terminals, a heat dissipation mechanism fixedly connected to the lower front and rear sides of the outer wall of the machine tool, the heat dissipation mechanism being used to dissipate heat from the plastic mold, and a sliding mechanism fixedly connected to the front and rear sides of the bottom of the outer wall of the machine tool; the grinding mechanism includes an abrasive brush wheel, the abrasive brush wheel being installed on the left side of the outer wall of the machine tool, a connecting shaft fixedly connected to the middle of the abrasive brush wheel, a worm gear fixedly connected to the bottom of the outer wall of the connecting shaft, a grinding box provided on the outer side of the abrasive brush wheel, a motor being provided on the front side of the outer wall of the grinding box, a worm fixedly connected to the output end of the motor, and the right side of the worm engaging with the left side of the outer wall of the worm gear.

[0006] As a further description of the above technical solution: The heat dissipation mechanism includes a cooling fan, which is installed on the lower middle part of the front and rear sides of the outer wall of the machine tool. A movable block is fixedly connected to the bottom of the cooling fan, and a battery is fixedly connected to the bottom of the movable block. A drive component is provided on the outside of the battery.

[0007] As a further description of the above technical solution: The drive assembly includes a second motor, which is mounted on the right side of the outer wall of the heat dissipation mechanism. A sprocket is fixedly connected to the output end of the second motor, and a threaded rod is fixedly connected to the left end of the outer wall of the sprocket. A chain is meshed with the outer wall of the sprocket, and the interior of the moving block is threadedly connected to the outer wall of the threaded rod.

[0008] As a further description of the above technical solution: The sliding mechanism includes a long plate, which is installed on the front and rear sides of the bottom of the outer wall of the machine tool, and a groove is formed in the upper middle part of the long plate.

[0009] As a further description of the above technical solution: The bottom of the motor is fixedly connected to a base plate, and the rear side of the base plate is fixedly connected to the front side of the bottom of the outer wall of the grinding box.

[0010] As a further description of the above technical solution: The inner wall of the grinding box is fixedly connected to a fixing plate on both the front and rear sides. The upper part of the inner wall of the fixing plate is rotatably connected to the outer wall of the worm gear.

[0012] As a further description of the above technical solution: The left and right ends of the threaded rod are rotatably connected to a second fixing plate, and the bottom of the second fixing plate is fixedly connected to the top of the long plate.

[0013] This utility model has the following beneficial effects: 1. In this utility model, a motor is connected to a worm gear to drive its rotation. The worm gear meshes with a worm wheel, thereby driving the connecting shaft to rotate. This causes the abrasive brush wheel connected to the other end of the connecting shaft to rotate synchronously, realizing the grinding operation of the stamped terminal. This mechanical grinding method replaces the electrolytic solution grinding process, avoids the use of pure water for multi-stage rinsing and drying processes, reduces water consumption and energy consumption, and lowers production costs.

The two ends of the threaded rod are limited by the second fixing plate fixed to the two ends of the long plate. The surface of the threaded rod is threadedly connected to the moving block. The upper and lower parts of the moving block are respectively welded to the cooling fan and the battery. The battery powers the cooling fan. The groove on the top of the long plate restricts the rotation of the battery. When the threaded rod rotates, the moving block moves along the threaded rod, driving the cooling fan and the battery to move synchronously, thereby achieving heat dissipation for the mold. This structure solves the problem of material thermal expansion and deformation caused by friction between the mold and the metal terminal during the stamping process, as well as the problem of uneven stamping gap.

Fixing plates 207 are fixedly connected to the front and rear sides of the bottom of the inner wall of the grinding box 208. The upper middle part of the inner wall of the fixing plate 207 is rotatably connected to the outer wall of the worm 204, which fixes the position of the worm 204 so that its position remains unchanged when it rotates. Specifically, motor 205 is connected to worm gear 204 to drive its rotation. Multiple fixing plates 207 are evenly distributed on worm gear 204, which are securely fixed inside the grinding box 208. Through holes are provided at the top for worm gear 204 to pass through and rotate, providing radial fixation and limiting for worm gear 204. A base plate 206 is fixedly connected to the bottom of motor 205. The rear side of the base plate 206 is fixedly connected to the front bottom of the outer wall of the grinding box 208, forming a stable support structure to prevent motor 205 from shaking or shifting due to rotation. Worm gear 205... A worm gear 203 is installed next to the worm 204 to mesh with it. When the worm 204 rotates, it drives the worm gear 203 to rotate synchronously through tooth surface meshing. The center hole of the worm gear 203 is welded to the connecting shaft 202. An abrasive brush wheel 201 is installed at the other end of the connecting shaft 202. The rotational motion of the worm gear 203 is transmitted to the abrasive brush wheel 201 through the connecting shaft 202, so that it rotates at high speed to polish the stamped terminals. The mechanical polishing method replaces the traditional electrolytic solution process, avoids the multi-stage rinsing and drying process of pure water, reduces water and energy consumption, and effectively reduces production costs.

[0019] Reference Figure 6The heat dissipation mechanism 3 includes a cooling fan 301, which is installed on the lower middle part of the front and rear sides of the outer wall of the machine tool 1. A moving block 302 is fixedly connected to the bottom of the cooling fan 301, and a battery 303 is fixedly connected to the bottom of the moving block 302. A drive assembly 304 is provided on the outside of the battery 303. The drive assembly 304 includes a second motor 3041, which is installed on the right side of the outer wall of the heat dissipation mechanism 3. A sprocket 3042 is fixedly connected to the output end of the second motor 3041. A threaded rod 3044 is fixedly connected to the left end of the outer wall of the sprocket 3042. A chain 3043 is meshed with the outer wall of the sprocket 3042. The inside of the moving block 302 is threadedly connected to the outer wall of the threaded rod 3044. The sliding mechanism 4 includes a long plate 401, which is installed on the front and rear sides of the bottom of the outer wall of the machine tool 1. A groove 402 is provided in the upper middle part of the long plate 401 to restrict the rotation of the battery 303. Specifically, one end of each of the two threaded rods 3044 is securely connected to a sprocket 3042. The surfaces of the two sprockets 3042 together form a transmission structure around the chain 3043. One end of one of the sprockets 3042 is connected to a second motor 3041. When the second motor 3041 starts, power is transmitted through the chain 3043, causing the two sprockets 3042 to rotate synchronously, thereby driving the threaded rods 3044 to rotate. Fixing plates 3046 are installed at both ends of the threaded rods 3044. The fixing plates 3046 are fixed to both ends of the long plate 401, providing axial fixation and radial limiting for the threaded rods 3044, ensuring their stability during rotation. A moving block 302 is threadedly connected to the surface of the threaded rods 3044. The internal threaded structure of the moving block 302 cooperates with the threaded rods 3044, converting the rotation of the threaded rods 3044 into linear motion of the moving block 302. The upper and lower sides of the moving block 302 are welded with… The cooling fan 301 and battery 303 are connected, with the battery 303 providing power to the cooling fan 301. The moving block 302 rigidly connects the two, allowing the battery 303 to move synchronously with the moving block 302. The top of the long plate 401 has a groove 402, into which the battery 303 is embedded. The shape of the groove 402 restricts the rotation of the battery 303, allowing it to move only along the axial direction of the threaded rod 3044. When the motor 3041 is turned on, the threaded rod 3044 rotates, driving the moving block 302 to move along the threaded rod 3044. Under the restriction of the groove 402, the battery 303 moves accordingly, thereby driving the cooling fan 301 to move synchronously, achieving dynamic heat dissipation for the mold. This mechanism, through the combination of mechanical transmission and structural limiting, solves the problem of material thermal expansion and deformation caused by friction between the mold and metal terminals during the stamping process, as well as uneven stamping gaps, ensuring the accuracy and stability of the stamping operation.

[0020] Reference Figure 1 and Figure 2The bottom of motor 3041 is fixedly connected to base plate 3045. The left side of base plate 3045 is fixedly connected to the right side of long plate 401 to fix motor 3041. The left and right ends of threaded rod 3044 are rotatably connected to fixing plate 3046. The bottom of fixing plate 3046 is fixedly connected to the top of long plate 401 to support threaded rod 3044. Specifically, the bottom of motor 2 3041 is welded to base plate 2 3045, and the left side of base plate 2 3045 is firmly connected to the right side of long plate 401, which can effectively limit the displacement and shaking of motor 2 3041 and provide a reliable fixed foundation for motor operation. The left and right ends of threaded rod 3044 are connected to fixed plate 2 3046 by rotational connection. The bottom of fixed plate 2 3046 is firmly fixed to the top of long plate 401. With its own rigidity, fixed plate 2 3046 provides a support point for threaded rod 3044, allowing threaded rod 3044 to rotate freely while preventing it from shifting or shaking during rotation, ensuring the stability and reliability of threaded rod 3044 rotation.

[0021] Working principle: The stamped terminals are placed into the grinding box 208 filled with abrasive. Turning on the motor 205 grinds the stamped terminals. Since the motor 205 is connected to the worm gear 204, it drives the worm gear 204 to rotate. Multiple fixing plates 207 are evenly distributed on the worm gear 204 and securely fixed inside the grinding box 208. The worm gear 204 can pass through and rotate from above, providing a fixing and limiting function. A worm wheel 20 meshes next to the worm gear 204. 3. When the worm 204 rotates, it can drive the worm wheel 203 to rotate. A connecting shaft 202 is welded inside the worm wheel 203, and the other end of the shaft is connected to the abrasive brush wheel 201. Therefore, when the worm wheel 203 rotates, the abrasive brush wheel 201 will also rotate synchronously, thereby polishing the stamped terminals. It has a strong cleaning effect and solves the problem that using electrolytic solution to polish terminals requires multiple rinsing and drying with pure water, which increases water consumption and energy consumption and increases production costs. By activating motor 3041, the moving block 302 drives the cooling fan 301 to move left and right, achieving the effect of cooling the mold. Since one end of each of the two threaded rods 3044 is securely connected to a sprocket 3042, with a chain 3043 tightly wrapped around its surface, and one end of one sprocket 3042 is connected to motor 3041, when motor 3041 is activated, the chain 3043 will cause the two sprockets 3042 to rotate, thereby causing the threaded rods 3044 to rotate. Fixing plates 3046 are also installed at both ends of the threaded rods 3044, fixed to both ends of the long plate 401, serving to fix and limit the movement of the threaded rods 3044. Moving blocks 3044 are also installed on the surface of the threaded rods 3044. 2. The internal structure allows the threaded rod 3044 to rotate in a threaded manner. A cooling fan 301 and a battery 303 are welded to the top and bottom of the moving block 302, respectively. The battery 303 provides sufficient power to the cooling fan 301, and the moving block 302 connects the two to achieve synchronous movement. A groove 402 is also provided on the top of the long plate 401 to restrict the rotation of the battery 303. Therefore, when the motor 3041 is turned on, the rotation of the threaded rod 3044 will cause the battery 303 set in the groove 402 to move, thereby driving the cooling fan 301 to move, thereby achieving heat dissipation of the mold and solving the problem of uneven stamping gap caused by the friction between the mold and the metal terminals during the stamping process, which leads to thermal expansion and deformation of the material.
