Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board processing technology, and in particular to a die positioning fixture. Background Technology

[0002] Die-cutting dies are the core molds for punched products and are indispensable in the product forming process of the circuit board industry. During die-cutting, the die must be precisely positioned on the mold frame of the processing equipment, and then removed after processing. Due to differences in product design dimensions, the dimensions of the PCB and the die will also differ. Since the mold frame of the processing equipment has a fixed size and defaults to the maximum size to accommodate dies of different sizes, setting the die on the mold frame requires a positioning operation.

[0003] In existing technologies, die positioning largely relies on direct manual operation. For dies of different specifications, the positioning reference needs to be readjusted, resulting in low operational efficiency. The lack of limiting structures on the die frame makes it easy for manual die placement to result in die position deviation due to operational errors. During processing, the die may also become loose, leading to problems such as incomplete punching. This phenomenon is particularly pronounced in products requiring high punching depth. Furthermore, operators directly touching the die's cutting edge during placement poses a safety risk and can cause scratches. To address these issues, Chinese utility model patent application CN209175922U discloses a flexible circuit board punching die, including a die base plate and a cover plate on top of the die base plate. The die base plate has positioning pins and corresponding clearance holes. It can be observed that although the setting of positioning pins and clearance holes can provide inspiration for the positioning of die-cutting molds and mold bases, it still cannot achieve the adaptation of the mold base to die-cutting molds of different sizes. How to provide a die-cutting mold positioning fixture that can adapt to die-cutting molds of different sizes is a technical problem that needs to be solved. Utility Model Content

[0004] To address the aforementioned technical problems, the purpose of this utility model is to provide a die-cutting positioning fixture, which solves the problem that existing technologies cannot quickly position die-cutting molds of different sizes.

[0005] Based on this, the present invention provides a die-cutting mold positioning fixture, which includes: The base plate is horizontally arranged, and a vertically arranged positioning plate is fixedly connected to any side of the base plate to abut against the first side of the die-cutting mold to stop the die-cutting mold. A plurality of limiting blocks are provided, and the plurality of limiting blocks are movably disposed on the base plate, including at least three of the limiting blocks: A limiting block is used to abut against the second side of the die, a limiting block is used to abut against the third side of the die, and a limiting block is used to abut against the fourth side of the die. The first side is adjacent to the second side, the first side is opposite to the third side, and the second side is opposite to the fourth side. The limiting block and / or the base plate are further provided with a limiting member that limits the position of the limiting block.

[0006] In some embodiments of this application, the limiting block or the base plate is a magnetic component.

[0007] In some embodiments of this application, both the limiting block and the base plate are magnetic components and their magnetic poles are opposite.

[0008] In some embodiments of this application, the positioning plate is disposed at the front end of the base plate and integrally formed with the base plate.

[0009] In some embodiments of this application, a first supplementary plate extending downward is fixedly provided at the front end of the base plate, and a second supplementary plate extending downward is fixedly provided at the front end of the side of the base plate, and the first supplementary plate and the second supplementary plate are fixedly connected to form a positioning angle.

[0010] In some embodiments of this application, a push-pull handle is fixedly connected to the first supplementary plate.

[0011] In some embodiments of this application, the push-pull handle is fitted with an anti-slip rubber sleeve.

[0012] In some embodiments of this application, the base plate includes a first assembly part, a second gradient part, a third forming part, and a fourth shrinking part arranged sequentially. The positioning plate and the first supplementary plate are fixedly connected to the front end of the first assembly part, and the second supplementary plate is fixedly connected to the left and right sides of the first assembly part. The horizontal dimension of the third forming part is smaller than the horizontal dimension of the first assembly part. The horizontal dimension of the second gradient part gradually decreases from the first assembly part to the third forming part. The horizontal dimension of the fourth shrinking part is smaller than the dimension of the third forming part.

[0013] In some embodiments of this application, the bottom of the limiting block is provided with a pick-up and put-out groove.

[0014] In some embodiments of this application, the base plate and the positioning plate are made of 1mm thick galvanized steel sheet.

[0015] This utility model provides a die-cutting mold positioning fixture, which has the following advantages compared with the prior art: This utility model provides a die-cutting mold positioning fixture, including a base plate, a positioning plate, and limiting blocks. The base plate is horizontally arranged, and the front end of the base plate is fixedly connected to the vertically arranged positioning plate. When the die-cutting mold is placed on the base plate, its first side abuts against the positioning plate. Multiple limiting blocks are provided, movably arranged on the base plate. At least one limiting block abuts against the second side, at least one limiting block abuts against the third side, and at least one limiting block abuts against the fourth side. For the die-cutting mold, the first and second sides are adjacent, the first and third sides are opposite, and the second and fourth sides are opposite. That is, at least three limiting blocks cooperate with the positioning plate to abut against the die-cutting mold, thereby limiting the die-cutting mold to the base plate. In addition, limiting members that restrict the position of the limiting blocks are also provided on the limiting blocks and / or the base plate. It should be noted that during the die-cutting mold positioning process, the limiting blocks can also be used to abut against the die-cutting mold, which can avoid direct contact between the operator and the die-cutting mold and eliminate the risk of cuts to the operator. Based on the above structure, during use, the die-cutting mold is placed on the base plate with its first side abutting against the positioning plate. The positioning plate, acting as a reference edge, provides initial positioning for the die-cutting mold. The die-cutting mold is then moved to slide along the positioning plate until it reaches the designated position. At this point, at least three limiting blocks abut against the second, third, and fourth sides of the die-cutting mold respectively. These limiting blocks cooperate with the positioning plate to limit the die-cutting mold's position. Furthermore, since the base plate or limiting blocks have limiting components that secure them, the limiting blocks are fixed to the base plate, thus also fixing the die-cutting mold to the base plate, effectively preventing mold displacement. In this way, the die-cutting mold positioning fixture of this application provides a reference edge for the die-cutting mold positioning operation by setting a positioning plate. Multiple limiting blocks, in conjunction with the positioning plate, clamp the die-cutting mold to achieve positioning and limiting, providing good positioning and limiting effects for various dies of different sizes. The die-cutting mold will not shift due to the clamping of the positioning plate and limiting blocks, reducing the failure rate of the processing equipment. Attached Figure Description

Detailed Implementation

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0019] It should be understood that the terms "before" and "after" are used in this utility model to describe various types of information, but these terms should not be limited to them. These terms are only used to distinguish information of the same type from each other. For example, "before" information can also be called "after" information, and "after" information can also be called "before" information, without departing from the scope of this utility model.

[0020] like Figures 1 to 4 As shown, this utility model embodiment provides a die-cutting mold positioning fixture, including a base plate 1, a positioning plate 2, and limiting blocks 3. The base plate 1 is horizontally arranged, and the front end of the base plate 1 is fixedly connected to the vertically arranged positioning plate 2. When the die-cutting mold is set on the base plate 1, the first side of the die-cutting mold abuts against the positioning plate 2. Multiple limiting blocks 3 are provided, and the multiple limiting blocks 3 are movably arranged on the base plate 1. At least one limiting block 3 abuts against the second side of the die-cutting mold, at least one limiting block 3 abuts against the third side of the die-cutting mold, and at least one limiting block 3 abuts against the fourth side of the die-cutting mold. For the die-cutting mold, the first side is adjacent to the second side, the first side is opposite to the third side, and the second side is opposite to the fourth side. That is, at least three limiting blocks 3 cooperate with the positioning plate 2 to abut against the die-cutting mold and thus limit the die-cutting mold to the base plate 1. In addition, the limiting blocks 3 and / or the base plate 1 are also provided with limiting members that limit the position of the limiting blocks 3. It should be noted that during the positioning process of the die-cutting mold, the limiting block 3 can be used to abut the die-cutting mold, which can avoid direct contact between the operator and the die-cutting mold and eliminate the risk of cut to the operator.

[0021] Based on the above structure, during use, the die-cutting mold is placed on the base plate 1 with its first side abutting against the positioning plate 2. The positioning plate 2 serves as a reference edge, providing initial positioning for the die-cutting mold. The die-cutting mold is then moved to slide along the positioning plate 2 until it reaches the designated position. At this point, at least three limiting blocks 3 abut against the second, third, and fourth sides of the die-cutting mold respectively. The limiting blocks 3 cooperate with the positioning plate 2 to limit the die-cutting mold. Since the base plate 1 or the limiting blocks 3 are equipped with limiting components that restrict the limiting blocks 3, the limiting blocks 3 are fixed to the base plate 1, thereby also fixing the die-cutting mold to the base plate 1, effectively preventing the die-cutting mold from shifting. Thus, the die-cutting mold positioning fixture of this application provides a reference edge for the positioning operation of the die-cutting mold by setting the positioning plate 2, and multiple limiting blocks 3 cooperate with the positioning plate 2 to clamp the die-cutting mold, achieving positioning and limiting of the die-cutting mold. It has good positioning and limiting effects for various dies of different sizes; the die-cutting mold will not shift due to the clamping of the positioning plate 2 and the limiting blocks 3, reducing the failure rate of the processing equipment.

[0022] Regarding the limiting component in this application, it can be adjusted to improve the limiting block and the base plate, such as... Figure 1 As shown, in some embodiments of this utility model, the limiting block 3 or the base plate 1 is preferably a magnetic component. Thus, the base plate 1 can attract the limiting block 3, thereby fixing the limiting block 3 onto the base plate 1. Of course, both the base plate 1 and the limiting block 3 can also be preferably magnetic components, in which case the magnetic poles of the base plate 1 and the limiting block 3 are different. In this case, the limiting block 3 can be fixed based on the attraction of the base plate 1, and there is no need to provide a limiting component.

[0023] Furthermore, when using the magnetic adsorption limiting block 3, a pick-and-place groove 7 is provided at the bottom of the limiting block 3, so the limiting block 3 is U-shaped. Based on the above structure, the operator can quickly grab the limiting block 3 through the pick-and-place groove 7 at the bottom, thereby completing the placement, storage and position adjustment of the limiting block 3. The structural design of the pick-and-place groove 7 is ingenious, and the operator has a good user experience.

[0024] Optionally, in this embodiment, the positioning plate 2 and the base plate 1 are integrally formed and made of 1mm thick galvanized steel plate, which simplifies the manufacturing process of the die-cutting positioning fixture and improves the structural strength. Correspondingly, the limiting block 3 of this application is a countersunk magnet, which can not only achieve a movable connection with the base plate 1, but also be fixed to the base plate 1 by bolts based on the countersunk hole setting to adapt to different working conditions.

[0025] Furthermore, in some embodiments of this application, a first supplementary plate 4 extending downward is fixedly connected to the front end of the base plate 1, and a second supplementary plate 5 extending downward is fixedly connected to the front end of the side of the base plate 1. The first supplementary plate 4 and the second supplementary plate 5 are fixedly connected to form a positioning angle. Based on the above structure, when the die-cutting positioning fixture is sent into the processing equipment, the positioning angle can abut against the die frame, improving the stability of the die-cutting in the processing equipment. Specifically, in the embodiments of this utility model, there are two first supplementary plates 4 and two second supplementary plates 5. The two first supplementary plates 4 are respectively located on both sides of the positioning plate 2 at the front end of the base plate 1, and the two second supplementary plates 5 are respectively located on the left and right sides of the base plate 1 and at the front end of the side.

[0026] Furthermore, to quickly and effectively push the die-cutting positioning fixture into the processing equipment, this application continues to provide push-pull handles 6 on the first supplementary plate 4. Corresponding to the number of first supplementary plates 4, two push-pull handles 6 are provided, each fixedly connected to one of the two first supplementary plates 4; the push-pull handles 6 are fitted with anti-slip rubber sleeves. The push-pull handles 6 facilitate safer and more convenient pushing and pulling operations for operators, and the anti-slip rubber sleeves also improve safety during use.

[0027] More specifically, such as Figure 4As shown, the base plate of this application includes a first assembly part 11, a second gradient part 12, a third forming part 13 and a fourth shrinking part 14 arranged sequentially. The positioning plate 2 and the first supplementary plate 4 are fixedly connected to the front end of the first assembly part 11, and the second supplementary plate 5 is fixedly connected to the left and right sides of the first assembly part 11. The horizontal dimension of the third forming part 13 is smaller than the horizontal dimension of the first assembly part 11. The horizontal dimension of the second gradient part 12 gradually decreases from the first assembly part 11 to the third forming part 13. The horizontal dimension of the fourth shrinking part 14 is smaller than the dimension of the third forming part 13. Based on the above structure, the first assembly part 11 serves as the base plate 1, connecting the positioning plate 2, the first supplementary plate 4, the second supplementary plate 5, and other auxiliary structures. The third forming part 13 and the fourth shrinking part 14 are the main areas for placing the die. Since there is no need to connect the auxiliary structures, the third forming part 13 and the fourth shrinking part 14 have reduced horizontal dimensions relative to the first assembly part 11 to reduce the weight of the entire base plate 1, which helps to save manufacturing costs. At the same time, in order to ensure that the first assembly part 11 and the third forming part 13 are effectively connected while further reducing the size of the structure, the horizontal dimension of the second gradient part 13 also gradually decreases as it extends from the first assembly part 11 to the third forming part 13.

[0028] In addition, such as Figure 5 As shown, in some other embodiments of this application, the limiting components are preferably connecting screws and connecting nuts. A groove 8 is provided on the base plate 1, and the connecting screw passes through the groove 8 and is fixedly connected to the limiting block 3. The other end of the connecting screw extends to the bottom of the base plate 1 and is fitted with a connecting nut. Based on the above structure, the limiting block 3 can slide along the groove 8 and abut against the die under the limiting position of the connecting screw. The connecting nut, in conjunction with the connecting screw, limits the limiting block 3 to the base plate 1. Simultaneously, based on the limiting of the four sides of the die, at least three grooves 8 are provided on the base plate 1.

[0029] The operation process of the die positioning fixture of this application is as follows: When in use, the die is placed on the base plate 1, and the die is initially positioned by the positioning plate 2 against the die. Then, the limiting blocks 3 are set along the three sides of the die to position and fix the die. Next, the operator places the product to be punched on the die and pushes the die positioning fixture into the punching die holder by the push-pull handle 6. At this time, the positioning angle formed by the first supplementary plate 4 and the second supplementary plate 5 completes the precise positioning cooperation with the punching die holder. The punch press is started to complete the punching process. After the processing is completed, the push-pull handle 6 is pulled to pull the die positioning fixture out of the punching die holder and take out the punched product.

[0030] In summary, this utility model provides a die-cutting mold positioning fixture, including a base plate, a positioning plate, and limiting blocks. The horizontally arranged base plate is fixedly connected to the vertically arranged base plate. Several limiting blocks with magnetic dissimilarity are movably disposed on the top of the base plate, and each set of limiting blocks cooperates with the positioning plate to abut the die-cutting mold. When the die-cutting mold is placed on the base plate, one side of the die-cutting mold abuts against the positioning plate, and the several limiting blocks abut against the remaining sides of the die-cutting mold, thereby fixing the die-cutting mold to the base plate. Compared with the prior art, the die-cutting mold positioning fixture of this application uses the positioning plate as the positioning reference for the die-cutting mold, and cooperates with the limiting blocks to clamp the die-cutting mold to achieve positioning and limitation. It has a good positioning effect for various dies of different sizes; the die-cutting mold will not shift due to the clamping of the positioning plate and limiting blocks, reducing the failure rate of processing equipment; it effectively avoids direct contact between the operator and the die-cutting mold, eliminating the risk of cuts to the operator.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
