Description

Technical Field

[0001] This utility model relates to the field of processing mold technology, specifically to a mold for preventing circuit board punching jams. Background Technology

[0002] With the development of market demand, product styles are becoming more diverse, and more and more product shapes are developing towards being thinner, shorter, or larger in size. Customers are becoming more and more demanding on the dimensional tolerances of products. In the traditional product stamping principle, flexible circuit boards are processed by making the punch and blanking hole of the stamping die into a shape that can be nested with each other.

[0003] When the die is used to punch and pull out the product, the circuit board is fixed to the lower die plate with the blanking hole by the positioning pin. The punch falls downward under the action of mechanical force and is tangential to the blanking hole, forming a scissor-like effect. The excess part (scrap) other than the desired product is punched and pressed into the blanking hole. The die cuts and separates the FPC from the unwanted part. However, in the process of use, the positioning of the punching and pulling machine, the wrinkles of the product or the jamming of the product have certain influence factors on the transfer of the stamped product. Due to the jamming, the product cannot be automatically and smoothly transferred to the next stamping step, resulting in abnormalities such as product jamming and tearing. How to solve the jamming problem in the product processing is particularly important. Therefore, a die to prevent the jamming of circuit board punching is needed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a die for preventing circuit board punching jams. By adding a stripping ring to the traditional die, it aims to reduce the occurrence of abnormalities and improve operational efficiency.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] This application provides a die to prevent circuit board stamping jams, solving the problem that existing dies are prone to jamming during use, which can prevent the automatic and smooth transfer of products for the next stamping step, leading to product jamming and tearing.

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] This utility model discloses a die for preventing circuit board punching jams, according to the attached... Figure 1 As shown, it includes an upper die fixing plate 1 and a lower die fixing plate 5. The upper die fixing plate 1 is provided with a punch fixing plate 2, the lower die fixing plate 5 is provided with a lower template 4, and the punch fixing plate 2 is provided with a movable template 3. The upper die fixing plate 1 and the lower die fixing plate 5 are used to fix the position of the punch fixing plate 2 and the lower template 4, respectively. The punch 6 is fixedly connected to the punch fixing plate 2, and the punch fixing plate 2 is used to fix the position of the punch 6.

[0023] A stripper ring 9 is slidably connected inside the punch fixing plate 2. A spring is fixedly connected between the stripper ring 9 and the inner cavity of the punch fixing plate 2. A cavity for accommodating the flexible circuit board 14 is provided between the moving template 3 and the lower template 4. The flexible circuit board 14 is snapped between the moving template 3 and the lower template 4. The stripper ring 9 can move within a certain range and is subjected to the elastic force of the spring. The stripper ring 9 passes through the moving template 3 and extends downward. Its design purpose is to help the flexible circuit board 14 smoothly detach from the mold during the punching process and prevent jamming.

[0024] The stripping ring 9 is conical in shape, which provides better support for the flexible circuit board 14 and is suitable for use with more models of flexible circuit boards 14. This makes it easier to lift the flexible circuit board 14 after punching and ensures smooth stripping.

[0025] The device uses the downward pressing action of the upper die to press the stripping ring 9 under pressure. When the moving platen 3 is pulled up, the stripping ring 9 exerts upward force to bounce the product up, so that the product does not get stuck after punching, thus achieving a smooth conveying effect.

[0026] The upper die fixing plate 1 and the punch fixing plate 2 are equipped with spring pins 13 inside, which are connected to the moving die plate 3. The spring pins 13 are used to provide additional support and stability, and provide a certain buffer and guiding effect when the moving die plate 3 moves.

[0027] The lower template 4 and the lower mold fixing plate 5 are provided with a discharge port 7; the discharge port 7 is used to discharge waste or finished products from the mold after stamping.

[0028] The stripper ring 9 is provided with a positioning pin 10, which is used to ensure the correct position of the stripper ring 9 in the punch fixing plate 2 and prevent it from moving improperly.

[0029] A guide structure 8 is provided between the punch fixing plate 2, the moving template 3, and the lower template 4. The guide structure 8 ensures the precise alignment and movement of the punch fixing plate 2, the moving template 3, and the lower template 4 during the punching process. The guide structure 8 includes a guide post 11 and a guide sleeve 12. The guide post 11 is set on the punch fixing plate 2 and the moving template 3, and the guide sleeve 12 is set on the lower template 4. The guide post 11 and the guide sleeve 12 are engaged. Through the engagement of the guide post 11 and the guide sleeve 12, a stable and precise guiding effect is provided. When the punch fixing plate 2, the moving template 3, and the lower template 4 move relative to each other, the guide post 11 and the guide sleeve 12 automatically align and engage. Through the engagement limit state, the position of the parts in the entire punching process is limited, thereby improving the stability of the equipment in the punching process.

[0030] The moving template 3 is equipped with a punch 6, which is the main component for punching operations. It is used to punch out the required shape or hole on the flexible circuit board 14. After punching out the required shape or hole, the waste material is discharged through the discharge port 7, which facilitates waste collection.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
