Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, and in particular relates to a high-efficiency stamping die for connectors. Background Technology

[0002] Stamping dies are molds used for stamping metal or other materials. Connectors are common connecting components in the electronics industry, used to connect and disconnect circuits, and are widely used in electronic equipment, home appliances, communication equipment, and other fields. Connector stamping dies are stamping dies specifically designed for producing connectors.

[0003] Currently, in the stamping process of connector terminals, it is generally a one-out-two-stamping process, that is, in one stamping stroke, the stamping die can produce two identical connector terminals at the same time. Then, the workers remove them from the die, replace them with new materials, and continue the stamping process. However, in actual use, one-out-two-stamping is still relatively slow in mass production, the number of parts produced at one time is small, and the material utilization rate and production efficiency are low. Therefore, this utility model proposes a high-efficiency stamping die for connectors. Utility Model Content

[0004] This utility model provides a high-efficiency stamping die for connectors. The stamping mechanism drives the upper die to press the material on the lower die downwards, performing a one-out-of-four stamping process. This allows for the production of four identical connector terminals in a single stamping stroke, improving material utilization and production efficiency. Simultaneously, the clamping mechanism clamps and fixes the material on the lower die, keeping it stable during the stamping process. Furthermore, the demolding mechanism enables the stamped connector terminals to be quickly demolded and ejected, facilitating subsequent stamping operations and reducing time waste. In summary, this invention solves the problems in the prior art.

Four pairs of extrusion blocks are placed on the top end of the lower mold, and a connecting rod is fixedly connected between the four extrusion blocks on one side and one side of the U-shaped plate.

[0014] Furthermore, two pairs of sliders are fixedly connected to the bottom ends of each pair of U-shaped plates, and two pairs of grooves are chiseled at the top of the base, with the sliders located in the grooves and slidably connected to them.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0035] Please see Figures 1-6 As shown, this utility model provides a high-efficiency stamping die for connectors, comprising:

[0036] The base 1 has a lower mold 2 fixedly connected to its top, and the top of the lower mold 2 is provided with an upper mold 3 that matches it.

[0037] The stamping mechanism 4 is located on the top of the base 1 and is used to drive the upper mold 3 downward to close with the lower mold 2.

[0038] The clamping mechanism 6 is located on the top of the base 1 and is used to fix the material on the lower mold 2.

[0039] The demolding mechanism 7 is located inside the lower mold 2 and is used to drive the stamped connector terminals to demold.

[0040] The stamping mechanism 4 includes a pair of slide cylinders 401 that are fixedly connected to the top of the base 1. The output ends of the pair of slide cylinders 401 are fixedly connected to connecting plates 402, and the opposite sides of the pair of connecting plates 402 are fixedly connected to the outer wall of the upper mold 3. The top of the base 1 is fixedly connected to two pairs of T-shaped rods 403, and the upper mold 3 is sleeved between the outer walls of the two pairs of T-shaped rods 403. The outer walls of the two pairs of T-shaped rods 403 are each sleeved with a first spring 404, and the two ends of the first spring 404 are fixedly connected to the bottom end of the upper mold 3 and the top end of the base 1, respectively.

[0041] In the specific implementation process, the material is placed on the lower mold 2 and fixed. A pair of sliding cylinders 401 drive the upper mold 3 to move downward along the two pairs of T-shaped rods 403 and compress the first spring 404, causing the upper mold 3 to approach the lower mold 2 and perform a one-out-four-stamping on the material, stamping out four identical connector terminals at one time, which effectively improves the material utilization rate and production efficiency.

[0042] The lower mold 2 has two pairs of evenly spaced cavities 201 at its top, and the upper mold 3 has two pairs of punches 301 fixedly connected to its bottom, with the punches 301 matching the cavities 201.

[0043] Through the mutual cooperation of punch 301 and cavity 201, punch 301 has the required connector terminal shape. During stamping, punch 301 applies pressure to the material, causing the material to undergo plastic deformation, thereby forming the required shape. At the same time, cavity 201 provides the internal contour of the final shape of the stamped material, which cooperates with punch 301 to complete the forming of connector terminal.

[0044] The clamping mechanism 6 includes two pairs of telescopic cylinders 601. The bottom ends of the two pairs of telescopic cylinders 601 are fixedly connected to the top end of the base 1 with support plates 5. The output ends of the pair of telescopic cylinders 601 are fixedly connected with U-shaped plates 602, and the bottom end of the U-shaped plates 602 is slidably connected to the top end of the base 1. Four pairs of extrusion blocks 604 are placed on the top end of the lower mold 2, and the four extrusion blocks 604 on one side are fixedly connected to one side of the U-shaped plates 602 with connecting rods 603.

[0045] Two pairs of telescopic cylinders 601 drive a pair of U-shaped plates 602 to move in opposite directions, which in turn drive four pairs of extrusion blocks 604 to move in opposite directions via connecting rods 603. This extrudes and fixes the material on the lower mold 2 in the front-back direction, keeping the material stable during the stamping process and preventing it from shifting, thus reducing stamping errors.

[0046] Two pairs of sliders 606 are fixedly connected to the bottom of each pair of U-shaped plates 602. Two pairs of grooves 605 are cut at the top of the base 1, and the sliders 606 are located in the grooves 605 and are slidably connected to them.

[0047] As the slider 606 slides along the U-shaped plate 602 inside the groove 605, it can assist the movement of the U-shaped plate 602, making it maintain stable movement. Specific Implementation Example 2:

[0049] Please see Figures 1-2 and Figures 4-6 As shown, in a preferred embodiment, the demolding mechanism 7 includes two pairs of rectangular through frames 701, both pairs of rectangular through frames 701 are embedded and connected to the bottom end of the lower mold 2. A rectangular sliding plate 702 is slidably connected to the inner wall of the rectangular through frame 701, and a plurality of movable rods 703 are fixedly connected to the top of the rectangular sliding plate 702. A plurality of round holes are drilled at the bottom end of the cavity 201, and the round holes communicate with the top of the rectangular sliding plate 702. The tops of the plurality of movable rods 703 pass through the round holes and extend into the interior of the cavity 201. An internal round rod 704 is fixedly connected to the inner wall of the rectangular through frame 701, and a pair of moving blocks 705 and a second spring 706 are sleeved on the outer wall of the internal round rod 704. The two ends of the second spring 706 are fixedly connected to the inner wall of the rectangular through frame 701 and one end of the moving block 705, respectively. An inclined rod 707 is rotatably connected between the pair of moving blocks 705 and the opposite sides of the rectangular sliding plate 702.

[0050] In the specific implementation process, when the material is squeezed by the punch 301, it is recessed into the cavity 201, which drives multiple movable rods 703 to move downward, squeezing the rectangular sliding plate 702 downward, causing a pair of inclined rods 707 to separate from each other. At the same time, it drives a pair of moving blocks 705 to move away from each other along the built-in round rod 704 and compresses the second spring 706. After the stamping is completed, the punch 301 moves upward with the upper mold 3 and separates from the connector terminal. The pair of moving blocks 705, inclined rods 707 and rectangular sliding plate 702, which have lost their squeezing force, are reset under the elastic action of a pair of second springs 706, driving multiple movable rods 703 to move upward and pushing the connector terminal upward to separate from the cavity 201, realizing rapid demolding, which facilitates subsequent material handling and stamping operations and reduces time waste.

[0051] Among them, the outer walls of a pair of diagonal rods 707 are rotatably connected to connecting plates near both ends by rotating shafts and bearings, and the ends of the four pairs of connecting plates that are far apart are respectively fixedly connected to the opposite sides of a pair of moving blocks 705 and rectangular sliding plates 702.

[0052] The rotational connection between the diagonal bar 707 and the two pairs of connecting plates allows the diagonal bar 707 to move more flexibly, so as to adapt to different motion requirements.

[0053] Among them, the outer wall of the lower mold 2 is chiseled with multiple pairs of receiving grooves 8 near the left and right sides, and the inner walls of the multiple pairs of receiving grooves 8 are rotatably connected to auxiliary rollers 9 through bearings and rotating shafts.

[0054] By setting the auxiliary roller 9, rolling assistance can be provided when the material is fed and discharged in the left and right directions, reducing frictional resistance.

[0055] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0056] All standard parts used in the application documents can be purchased from the market. All components in this application document can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all electrically connected to the external main controller and power supply, and the main controller is a conventional known device that can play a control role.

[0057] The working principle of this utility model is as follows:

[0058] In use, the material is first placed on the lower mold 2. Then, two pairs of telescopic cylinders 601 are driven to move a pair of U-shaped plates 602 towards each other, which in turn drive four pairs of extrusion blocks 604 towards each other via connecting rods 603. This extrusion blocks press and fix the material on the lower mold 2 in the front-to-back direction. Next, a pair of sliding cylinders 401 drive the upper mold 3 to move downwards along the two pairs of T-shaped rods 403, compressing the first spring 404. This causes the upper mold 3 and punches 301 to approach the lower mold 2 and the cavity 201, and drives the two pairs of punches 301 to press the material. When the material is pressed by the punches 301, it is recessed into the cavity 201, and multiple movable cylinders are activated. The moving rod 703 moves downward, pressing the rectangular sliding plate 702 downward, causing a pair of inclined rods 707 to separate from each other. At the same time, it drives a pair of moving blocks 705 to move away from each other along the built-in round rod 704 and compresses the second spring 706. After four identical connector terminals are stamped out at once, the punch 301 moves upward with the upper mold 3 and separates from the connector terminals. The pair of moving blocks 705, inclined rods 707, and rectangular sliding plate 702, which have lost their compression, reset under the elastic action of the pair of second springs 706, driving multiple moving rods 703 to move upward and pushing the connector terminals upward to separate from the cavity 201, thus achieving rapid demolding.

[0059] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described.
