[0002] Terminals are core components in electronic devices that enable electrical connections, primarily used for signal or current transmission between wires and components, and between components themselves. Terminal manufacturing is the process of transforming raw materials (metal sheets, wires, etc.) into terminal products that meet functional requirements through a series of processes. The quality of these terminals directly affects the reliability, conductivity, and lifespan of electronic equipment.

[0003] The patent publication number "CN220717373U" entitled "A Terminal Stamping Die" includes a die base and an installation mechanism disposed above the die base. The installation mechanism includes an installation component and a connecting component. The installation component includes a slide groove and a die cavity. In this invention, by setting a connecting hole, when the pull rod is pulled, the connecting plate can retract through the return spring and the connecting groove. Then, the die cavity is slidably inserted between the slide groove and the die base. Finally, the connecting plate is engaged with the die cavity through the connecting bolt and the connecting hole.

[0004] However, in the existing terminal stamping die, wear and damage can occur between the upper punch and the lower die during the processing, causing problems when the die is closed during stamping, affecting the stamping effect. The upper punch cannot be easily replaced, reducing the practicality of the device. Utility Model Content

[0005] One objective of this invention is to provide a new technical solution for stamping and forming dies used in terminal processing.

[0006] According to a first aspect of the present invention, a stamping die for terminal processing is provided, comprising: a base, a support column, and a top plate. A stamping replacement mechanism and a cooling mechanism are provided above the base. The stamping replacement mechanism includes a lower die, which is fixedly connected to the upper end of the base. A cylinder is fixedly connected to the bottom end of the top plate. An upper die is connected to the bottom output end of the cylinder. A placement groove and a stamping cavity are provided inside the lower die. A module is installed at the bottom end of the upper die through an assembly component. A stamping block is fixedly connected to the bottom end of the module.

[0007] The assembly component includes a fixed base, which is fixedly installed inside the upper mold. A movable rod is slidably installed inside the fixed base. A retaining plate is connected to the end of the movable rod away from the fixed base. The retaining plate is locked inside the module. A pull rod is fixedly connected to the bottom end of the movable rod.

[0008] Preferably, a fixed rod is inserted inside the movable rod, and a spring is wound around the surface of the fixed rod. One end of the spring is connected to the movable rod, and the other end of the spring is connected to a damper. The damper is installed inside the fixed base.

[0009] Preferably, the upper mold has a rod inserted inside, and the rod is inserted inside the card plate and the module.

[0010] Preferably, a slider is fixedly connected to the side wall of the movable rod, and the slider is slidably disposed inside the slide groove, which is formed inside the fixed seat.

[0011] Preferably, the cooling mechanism includes a water inlet seat, which is fixedly installed on the outer wall of the lower mold. A water inlet pipe is installed on the water inlet seat, and a circulating cooling pipe is installed on the water inlet seat. The circulating cooling pipe is located inside the lower mold, and one end of the circulating cooling pipe away from the water inlet pipe is connected to a drain seat. The drain seat is fixedly installed on the side wall of the lower mold, and a drain pipe is connected to the outside of the drain seat.

[0012] Preferably, the circulating cooling pipe is arranged in a spiral shape.

[0013] 1. This utility model utilizes the cooperation of a lower mold, cylinder, upper mold, placement groove, stamping cavity, module, stamping block, fixed base, moving rod, clamping plate, fixed rod, spring, damper, and pull rod to place the terminal material to be stamped inside the placement groove. Then, the cylinder is activated, causing the upper mold to press downwards. The stamping block and stamping cavity work together to stamp the terminal. During stamping, damage to the stamping block can occur. When replacement is needed, pulling the pull rod moves the moving rod away from the module, simultaneously moving the clamping plate out of the module and upper mold, releasing the module's limit. This allows for convenient disassembly and assembly of the module and stamping block, facilitating the replacement of worn stamping blocks. This terminal processing stamping mold enables convenient terminal stamping and allows for easy disassembly and replacement of worn stamping blocks, preventing wear from preventing the stamping block from closing with the stamping cavity during stamping and affecting the stamping effect. This improves the practicality and convenience of the device.

[0014] 2. This utility model, through the cooperation of the water inlet seat, water inlet pipe, circulating cooling pipe, drain seat, and drain pipe, avoids the terminal temperature being too high, making it difficult to demold and remove. At this time, an external cooling water source can be injected from the water inlet pipe, allowing it to flow into the circulating cooling pipe. The circulating cooling pipe cools the bottom of the stamping cavity, absorbing the heat generated during stamping. The cooling water is then discharged from the drain pipe, circulating and cooling the terminal, facilitating demolding and removal. This invention enables the stamping die for terminal processing to circulate and cool the stamped terminal, making it easier to demold and remove, thus improving the practicality and convenience of the device.

Detailed Implementation

[0024] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0025] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0026] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0027] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0028] like Figure 1-6 As shown, one embodiment of this utility model is provided:

[0029] A stamping die for terminal processing. The base 111, support column 112 and top plate 113 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies known to those skilled in the art.

[0030] Includes: base 111, support column 112 and top plate 113. A stamping replacement mechanism 2 and a cooling mechanism 3 are provided above the base 111. The stamping replacement mechanism 2 includes a lower die 211, which is fixedly connected to the upper end of the base 111. A cylinder 212 is fixedly connected to the bottom end of the top plate 113. The bottom output end of the cylinder 212 is connected to the upper die 213. The lower die 211 has a placement groove 214 and a stamping cavity 215 inside. A module 216 is installed at the bottom end of the upper die 213 through an assembly component. A stamping block 217 is fixedly connected to the bottom end of the module 216.

[0031] The assembly component includes a fixed base 218, which is fixedly installed inside the upper mold 213. A movable rod 219 is slidably installed inside the fixed base 218. A clamping plate 220 is connected to one end of the movable rod 219 away from the fixed base 218. The clamping plate 220 is clamped inside the module 216. A pull rod 224 is fixedly connected to the bottom end of the movable rod 219.

[0032] When using this terminal to process the stamping die, the terminal material to be stamped is placed inside the placement groove 214. Then, the control cylinder 212 is started, and the upper die 213 is pressed downward. The terminal is stamped by the cooperation of the stamping block 217 and the stamping cavity 215. When the stamping block 217 and the stamping cavity 215 are used for stamping, the stamping block 217 may be damaged. When it needs to be replaced, pull the pull rod 224 to move the moving rod 219 away from the module 216. At the same time, the clamping plate 220 moves synchronously, so that the clamping plate 220 is moved out of the module 216 and the upper die 213, and the limit of the module 216 is released. The module 216 and the stamping block 217 can be easily disassembled and assembled, and the worn stamping block 217 can be easily replaced.

[0033] A fixed rod 221 is inserted inside the movable rod 219. A spring 222 is wound around the surface of the fixed rod 221. One end of the spring 222 is connected to the movable rod 219, and the other end of the spring 222 is connected to the damper 223. The damper 223 is installed inside the fixed base 218.

[0034] When installing a new stamping block 217, the pull rod 224 can be pulled to move the moving rod 219 and the clamping plate 220 away from the upper die 213. Then, the module 216 is inserted into the upper die 213. At this time, the spring 222 is in a compressed and stored state. When the pull rod 224 is released, the elastic force of the spring 222 automatically moves the moving rod 219 and the clamping plate 220, so that the clamping plate 220 enters the module 216 and the upper die 213 simultaneously for limiting, which facilitates installation.

[0035] The upper mold 213 has a rod 225 inserted inside, and the rod 225 is inserted inside the card plate 220 and the module 216;

[0036] Inserting the insert rod 225 into the card plate 220 and module 216 simultaneously can vertically limit the card plate 220 inside the module 216, making the installation of the card plate 220 inside the module 216 more secure.

[0037] A slider 226 is fixedly connected to the side wall of the movable rod 219. The slider 226 is slidably disposed inside the slide groove 227, which is opened inside the fixed seat 218.

[0038] When the moving rod 219 moves, the slider 226 moves synchronously inside the slide groove 227, thereby limiting the movement of the moving rod 219 and making its sliding more stable.

[0039] The cooling mechanism 3 includes a water inlet seat 311, which is fixedly installed on the outer wall of the lower mold 211. A water inlet pipe 312 is installed on the water inlet seat 311, and a circulating cooling pipe 313 is installed on the water inlet seat 311. The circulating cooling pipe 313 is located inside the lower mold 211. One end of the circulating cooling pipe 313 away from the water inlet pipe 312 is connected to a drain seat 314. The drain seat 314 is fixedly installed on the side wall of the lower mold 211, and a drain pipe 315 is connected to the outside of the drain seat 314.

[0040] During the stamping process, to prevent the terminals from overheating and becoming difficult to demold and remove, an external cooling water source can be used to inject water from the inlet pipe 312, allowing it to flow into the circulating cooling pipe 313. The circulating cooling pipe 313 cools the bottom of the stamping cavity 215, absorbing the heat generated during stamping. The cooling water is then discharged from the drain pipe 315 for circulating cooling, facilitating demolding and removal of the terminals.

[0041] The circulating cooling pipe 313 is arranged in a spiral shape;

[0042] The circulating cooling pipe 313 is arranged in a spiral shape, which increases the cooling and heat absorption area of ​​the circulating cooling pipe 313 and improves the cooling effect.

[0043] Working principle:

[0044] When using this terminal to process the stamping die, the terminal material to be stamped is placed inside the placement groove 214. Then, the control cylinder 212 is started, and the upper die 213 is pressed downward. The terminal is stamped by the cooperation of the stamping block 217 and the stamping cavity 215. When the stamping block 217 and the stamping cavity 215 are used for stamping, the stamping block 217 may be damaged. When it needs to be replaced, pull the pull rod 224 to move the moving rod 219 away from the module 216. At the same time, the clamping plate 220 moves synchronously, so that the clamping plate 220 is moved out of the module 216 and the upper die 213, and the limit of the module 216 is released. The module 216 and the stamping block 217 can be easily disassembled and assembled, and the worn stamping block 217 can be easily replaced.

[0045] During the stamping process, to prevent the terminals from overheating and becoming difficult to demold and remove, an external cooling water source can be used to inject water from the inlet pipe 312, allowing it to flow into the circulating cooling pipe 313. The circulating cooling pipe 313 cools the bottom of the stamping cavity 215, absorbing the heat generated during stamping. The cooling water is then discharged from the drain pipe 315 for circulating cooling, facilitating demolding and removal of the terminals. This completes the operation.
