Description

Technical Field

[0001] This utility model relates to the field of connector mold technology, specifically a split-type irregular connector bending and cutting mold, which is suitable for bending and cutting operations of irregular pin connectors. Background Technology

[0002] In the field of electronics manufacturing, bending and cutting connectors is one of the key processes.

[0003] In the prior art, utility model patent with publication number CN222402956U relates to this technology, and the equipment disclosed therein is generally similar to conventional equipment currently on the market. The main structure includes: a lower template, upper template components at both ends of the top surface of the lower template, a feeding component at one end of the top surface of the lower template, a support component on the top surface of the lower template, a limiting component in the middle of the top surface of the lower template, and a guide component at one end of the top surface of the lower template.

[0004] However, existing technologies still have some problems. Existing bending dies often have shortcomings when dealing with irregularly shaped, complex, and multi-bend connectors. On the one hand, these dies struggle to achieve one-time bending, leading to low production efficiency. On the other hand, for irregularly shaped connectors, the dies are difficult to process and it's hard to ensure bending consistency, thus affecting product quality. These problems, to some extent, restrict the development of the electronics manufacturing industry, creating an urgent need for a die capable of efficiently and accurately completing the bending and cutting of irregularly shaped connectors. Summary of the Invention

[0005] The purpose of this invention is to provide a split-type irregular connector bending and cutting mold to solve the problems of low efficiency, poor consistency and high processing difficulty of existing molds in the bending and cutting process of irregular connectors.

[0006] The technical solution of this utility model is as follows: A split-type irregular connector bending and cutting mold includes a left fixing block, a right fixing block, sliders, and a cutter. The left and right fixing blocks are connected by positioning pins, and four sliders are nested above them: a lower left slider, an upper left slider, a lower right slider, and an upper right slider. The lower left slider is connected to the left fixing block by a limiting pin, and the cutter is located above the upper right slider.

[0007] The lower part of the left fixed block is provided with a limiting through groove for positioning the connector housing, and the upper side is provided with a sliding groove (including sliding groove one, sliding groove two and sliding groove three). The right side is provided with a semi-circular through groove two for fixing the connector pins vertically. The upper surface of the left fixed block is provided with a semi-circular through groove one and a limiting pin hole close to the lower left slider. The connection between the semi-circular through groove one and the semi-circular through groove two is provided with an arc. The four corners of the left fixed block are provided with positioning pin holes one.

[0008] The right fixing block has a limiting groove 2 for positioning the connector housing below it, and positioning pin holes (including positioning pin hole 1 and positioning pin hole 2) at the four corners that are consistent with the positioning pin holes of the left fixing block. The upper side has a sliding groove (including sliding groove 4, sliding groove 5 and sliding groove 6). The left side has a semi-circular through groove 3 for fixing the connector pins in the vertical direction. The semi-circular through groove 3 and the semi-circular through groove 2 of the left fixing block form a circular hole.

[0009] The lower left slider has a semi-circular groove three on the right side for the limit connector pin, and a positioning pin hole three inside that runs vertically through and connects to the left fixed block.

[0010] The three surfaces below the lower right slider, close to the right fixed block, the left side surface, and the inclined surface close to the upper left slider, are provided with semi-circular through slots (including semi-circular through slot four, semi-circular through slot five, and semi-circular through slot six) for limiting connector pins. The connection of these three surfaces of the semi-circular through slots is provided with bent rounded corners (including bent rounded corner one and bent rounded corner two), and sliding lugs are provided on both sides.

[0011] The upper left slider has two sliding lugs on both sides, a through groove on the left side to avoid the connector pin holder, and semi-circular grooves (including semi-circular groove one and semi-circular groove two) for limiting the connector on the lower and right sides.

[0018] Furthermore, the elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0019] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings: As shown in Figure 1, the split-type irregular connector bending and cutting mold provided by this utility model mainly consists of a left fixing block 1, a right fixing block 8, a slider, and a cutter 5. The left and right fixing blocks are connected by positioning pins 9, forming the basic frame of the mold. Above the left and right fixing blocks, four sliders are nested: a lower left slider 3, an upper left slider 4, a lower right slider 7, and an upper right slider 6. The lower left slider 3 is connected to the left fixing block 1 by a limiting pin 2, and the cutter 5 is provided above the upper right slider 6 to realize the bending and cutting functions.

[0020] As shown in Figure 2, the left fixing block 1 has a limiting through groove 16 for positioning the connector housing below, used to fix the position of the connector housing. On the upper side of the left fixing block 1, there are three sliding grooves 11, 13, and 14 for sliding the slider and cutter 5, providing a track for the slider's movement. On the right side, there is a semi-circular through groove 17 for fixing the connector pins vertically. The upper surface of the left fixing block 1, close to the plane of the lower left slider 3, has a semi-circular through groove 10 and a limiting pin hole 18. An arc 15 is provided at the connection between the semi-circular through groove 10 and the semi-circular through groove 17. The left fixing block 1 has four positioning pin holes 12 at its four corners. The right fixing block 8 has a similar structure to the left fixing block 1, as shown in Figure 3. It also has a limiting through groove 19 for positioning the connector housing below, and the positioning pin holes 20 at its four corners are consistent with the positioning pin holes 12 of the left fixing block 1. Precise connection between the left and right fixing blocks is achieved through positioning pins 9. The upper side of the right fixed block 8 is also provided with slide groove 4 21, slide groove 5 22 and slide groove 6 23 for sliding of the slider and cutter 5, which together with the left fixed block 1 provide sliding space for the slider. The left side is provided with a semi-circular through groove 3 24 for fixing the connector pin in the vertical direction. The semi-circular through groove 3 24 and the semi-circular through groove 2 17 of the left fixed block 1 form a circular hole.

[0021] As shown in Figure 6, the lower left slider 3 has a semi-circular groove 39 on its right side for limiting connector pins, and a positioning pin hole 36 inside that passes through and connects to the left fixed block 1, thus realizing the installation and positioning of the lower left slider 3. The structure of the lower right slider 7 is more complex, as shown in Figure 4. On its lower surface near the right fixed block 8, its left side surface, and its inclined surface near the upper left slider 4, there are semi-circular grooves 4 25, 5 27, and 6 29 for limiting connector pins. At the connection of the three surfaces, there are bent rounded corners 1 26 and 28. There are sliding lugs 30 on both sides. By sliding the sliding lugs 30 in the groove, the installation and sliding positioning of the lower right slider 7 are completed.

[0022] The structure of the upper left slider 4 is shown in Figure 5. It has sliding lugs 31 on both sides, a through groove 32 on the left side to avoid the connector pin holder, and semicircular grooves 33 and 34 on the lower and right sides for limiting the connector. The pins at the connection between semicircular groove 33 and through groove 32 have a rounded bend 35. The structure of the upper right slider 6 is shown in Figure 6. It has a semicircular through groove 40 on the left side to limit the connector pins and a through groove 41 to avoid the connector pin holder. Sliding lugs 42 on both sides allow the upper right slider 6 to be installed and positioned by sliding the lugs 42 within the grooves.

[0023] The structure of the cutter 5 is shown in Figure 7. It has sliding lugs 43 on both sides and an inclined surface 37 on the left side, with the inclined surface 37 forming an angle of 60° with the horizontal plane. The cutter 5 is installed and slidably positioned by sliding the sliding lugs 43 in the groove, and is used to cut off the excess part of the connector pins.

[0024] The specific implementation process is as follows: First, insert the lower left slider 3 horizontally along the groove of the left fixed block 1 and fix it inside the left fixed block 1 using the limiting pin 2. Next, place the connector in the limiting through groove 16 below the left fixed block 1, ensuring that the connector pins are located in the semi-circular through groove 17 of the left fixed block 1. Then, use the clamping device to clamp the left and right fixed blocks together using the positioning pin 9. At this time, the connector pins are firmly fixed in the circular hole formed by the semi-circular grooves of the left and right fixed blocks.

[0025] Next, slide the lower right slider 7 to the left along the groove of the right fixing block 8 until the right side of the lower right slider 7 is flush with the right side of the right fixing block 8, completing the first and second bends of the connector. Immediately afterward, push the upper left slider 4 to the right along the groove of the left fixing block 1 until the left side of the upper left slider 4 is flush with the left side of the left fixing block, completing the third bend of the connector. Then, slide the upper right slider 6 to the left along the groove of the right fixing block 8 until the right side of the upper right slider 6 is flush with the right side of the right fixing block 8, completing the fourth bend of the connector. Through these operations, the four sliders work together to bend the connector pins into the predetermined shape.

[0026] Finally, the cutter 5 is pushed to the left along the groove of the right fixed block 8, cutting off the pins exposed on the upper surfaces of the upper left slider 4 and the upper right slider 6. At this point, the entire bending and cutting process is complete, and a non-standard connector meeting the requirements is successfully produced.

[0027] In summary, this utility model, through optimizing the mold structure and adopting a split modular design, achieves efficient and precise bending and cutting of irregularly shaped connectors. It has significant innovation and practicality, and can be widely used in the field of electronic manufacturing to improve the production quality and efficiency of connectors.
