Description

Technical Field

[0001] This invention relates to the field of melt molding technology, and more specifically to a melt molding die. Background Technology

[0002] A fuse is a simple and effective protective electrical appliance, mainly used for overload and short-circuit protection of circuits. Inside the fuse is a fusible element connected in series in the circuit being protected. When a short-circuit fault occurs, the fusible element melts instantly, breaking the circuit and providing protection. The manufacturing process of the fusible element typically involves a forging process to form the fusible element.

[0003] In related technologies, the forging process for melt forming is usually carried out in segments, which results in poor dimensional accuracy of segmented forging. A multi-segment melt needs to be processed multiple times, and the melt shape has poor consistency, resulting in low melt production efficiency. Summary of the Invention

[0004] In view of this, the present invention provides a melt forming mold to solve the problems of low efficiency and poor precision when forming melt in multiple stages.

[0005] This invention provides a melt forming mold, comprising:

[0006] The mold body is formed with a stamping groove, and has a material receiving cavity suitable for accommodating materials, and has a guide groove extending along a first direction.

[0007] A pressing assembly is at least partially disposed within a guide groove and adapted to move relative to the mold body along a first direction. The pressing assembly is disposed along the first direction on the side of the material receiving cavity away from the stamping groove. The pressing assembly includes a plurality of pressing units, which are arranged along a second direction. Each pressing unit includes a stamping part and a pressing part. The stamping part is located at the end of the pressing unit along the first direction that is close to the stamping groove and matches the shape of the stamping groove. The pressing part is located at the end of the pressing unit along the first direction that is away from the stamping part.

[0008] The movable pressure plate is adapted to move along the second direction and press the pressing part of the pressure block unit in sequence, so that the pressure block unit moves along the first direction to press the material.

[0009] Beneficial Effects: This invention provides a melt forming mold. During forging, the material is placed in a material receiving cavity. The mold body is formed with a stamping groove, which is opened on one side of the material receiving cavity near the mold body along a first direction. A guide groove extending along the first direction is opened on the other side. By providing the guide groove extending along the first direction, the pressing block assembly is accommodated within the guide groove and is suitable for moving relative to the mold body along the first direction. The pressing block assembly includes multiple pressing block units. By arranging the pressing block units along a second direction, the melt can be... The number of pressing units is used to form multi-segment molding of different shapes. The pressing unit includes a pressing part and a stamping part. During the forging process, the stamping part passes through the material receiving cavity and abuts against the material. The pressing part is moved by the moving pressure plate along the second direction and presses in sequence. Moving and pressing in sequence can avoid the material being subjected to force at the same time, resulting in excessive deformation and failure such as tearing. The external force applied by the moving pressure plate is transmitted to the pressing part and then to the stamping part, which can cause the material to act on the stamping groove and deform, and finally obtain the target melt, realizing the one-time molding of multi-segment melt.

[0010] In one alternative embodiment, the stamping groove includes:

[0011] The first stamping groove, the second stamping groove, and the third stamping groove are arranged adjacent to each other along the second direction, and the third stamping groove is disposed at at least one end of the stamping groove along the second direction. The number of the first stamping groove and the second stamping groove is multiple.

[0012] The pressing unit includes: a first pressing block and a second pressing block; the first pressing block has a first stamping portion at one end near the stamping groove along a first direction, and the second pressing block has a second stamping portion at one end near the stamping groove along the first direction, and the first pressing block and the second pressing block are connected in a cooperating manner; the first stamping portion and the second stamping portion are respectively matched with the shapes of the first stamping groove and the second stamping groove;

[0013] The pressing block assembly further includes: a third pressing block disposed at at least one end of the pressing block assembly along the second direction, wherein the end of the third pressing block near the stamping groove along the first direction has a third stamping portion; the shape of the third stamping portion matches that of the third stamping groove.

[0014] Beneficial effects: During the forging process, the required melt may have various shapes, and the stamping groove needs to match the melt. By setting a first stamping groove, a second stamping groove, and a third stamping groove, the stamping groove is divided into three different types: the first stamping groove, the second stamping groove, and the third stamping groove. At the same time, the pressing block unit includes a first pressing block and a second pressing block. The first pressing block and the second pressing block have a first stamping part and a second stamping part at the end near the stamping groove along the first direction. The first stamping groove and the second stamping groove correspond to and match the first stamping part and the shape. By setting a third pressing block at at least one end of the pressing block assembly along the second direction, the third pressing block has a third stamping part at the end near the stamping groove along the first direction, so that the third stamping part corresponds to and matches the third stamping groove and the shape matches. This is beneficial for obtaining different melt shapes according to work needs when forging melt, and also meets the technical requirement that multiple melts can be forged at one time.

[0015] In one alternative embodiment, the first stamping part is adapted to stamp the material into a V-shaped structure, the second stamping part is adapted to stamp the material into a flat planar structure, and the third stamping part is adapted to stamp the material into a right-angled structure.

[0016] Beneficial effects: By setting different shapes for the first stamping section, the second stamping section and the third stamping section, the shape of the melt obtained after forging is different, which helps to better meet the forging requirements of the melt required for the work.

[0017] In one alternative embodiment, a portion of the pressing block assembly moves relative to the mold body in a first direction within a guide groove and is elastically connected to the mold body. The pressing block assembly generates displacement in the first direction by external force compression in the first direction, which varies with the magnitude of the external force.

[0018] Beneficial effects: After the moving component moves along the second direction and presses the pressing block component in sequence, the pressing block component is elastically connected to the mold body. This allows the pressing block component to be reset after it is displaced along the first direction by external force and the external force disappears. This facilitates repeated forging, improves work efficiency, and saves time and costs.

[0019] In one alternative implementation, the guide groove includes:

[0020] A snap-fit ​​groove extends along the first direction and is disposed on the inner wall of the mold body near the guide groove;

[0021] The first pressing block engages with the locking groove, and a locking space is formed between adjacent first pressing blocks. The locking space is suitable for accommodating the second pressing block.

[0022] Beneficial effects: The guide groove is suitable for accommodating part of the pressure block assembly, and the corresponding snap-fit ​​groove is suitable for accommodating the first pressure block. By arranging the first and second pressure blocks adjacent to each other, a snap-fit ​​space is formed between the adjacent first pressure blocks. The snap-fit ​​space is suitable for accommodating the second pressure block, providing structural support for the elastic connection between the pressure block assembly and the mold body. The connection structure between the pressure block unit and the guide groove is simple and convenient for disassembly and installation.

[0023] In one alternative embodiment, the guide groove further includes:

[0024] The first snap-fit ​​boss is disposed at the end away from the movable pressure plate along the first direction, and is arranged adjacent to the snap-fit ​​groove along the second direction;

[0025] The second pressing block includes: a second snap-fit ​​boss, at least one of which is disposed at one end of the second pressing block along a third direction, the second snap-fit ​​boss and the first snap-fit ​​boss forming a snap-fit ​​cavity in the first direction;

[0026] The pressure block assembly also includes a spring disposed in the snap-fit ​​cavity along the first direction, with the two ends of the spring abutting against the first snap-fit ​​boss and the second snap-fit ​​boss respectively.

[0027] Beneficial effects: The guide groove has a first snap-fit ​​boss, and the second pressure block has a second snap-fit ​​boss. The first snap-fit ​​boss and the second snap-fit ​​boss correspond to each other along the first direction to form a snap-fit ​​cavity. The snap-fit ​​cavity is suitable for accommodating the spring, so that the pressure block assembly and the mold body are elastically connected. By setting the spring in the snap-fit ​​cavity, the pressure block assembly can automatically complete the reset after forging.

[0028] In one optional embodiment, the first pressing block is provided with a first protrusion in the opposite direction to the moving pressing plate; the second pressing block is provided with a second protrusion in the moving pressing plate direction, the first protrusion is provided relatively close to the moving pressing plate, and the second protrusion is provided relatively far away from the moving pressing plate, and the first protrusion and the second protrusion abut against each other.

[0029] Beneficial effects: By setting the first protrusion and the second protrusion, when the second pressing block is rebounded by the spring force, the first pressing block is subjected to the force of the second pressing block in the rebound direction. The second protrusion is close to the stamping groove relative to the first protrusion in the rebound direction, so that the second protrusion can abut against the first protrusion during the reset process of the second pressing block, thereby driving the first pressing block to reset.

[0030] In one alternative embodiment, a cover plate is provided away from the movable pressure plate along a first direction, and the cover plate is slidably connected to the movable pressure plate along a second direction.

[0031] The first direction and the second direction are not parallel, and the third direction is perpendicular to the first direction and the second direction, respectively.

[0032] Beneficial effect: By setting the cover plate to transmit the force to the moving pressure plate along the first direction, the moving pressure plate has the force to press the pressure block assembly along the first direction, thereby achieving the forging effect of the pressure block assembly.

[0033] In one alternative embodiment, the mold body includes:

[0034] A first mold and a second mold, the first mold being adapted to accommodate a portion of the pressing block assembly, the second mold having a stamping groove on the side near the pressing block assembly, the first mold and the second mold being detachably connected.

[0035] Beneficial effects: By splitting the mold body into a first mold and a second mold, it is easier to install and disassemble the mold body. It also allows for simpler and more effective processing of internal structures such as stamping grooves and material receiving cavities that are not conducive to overall processing, thereby improving the processing efficiency of the mold body.

[0036] In one alternative embodiment, the movable pressure plate is provided with a drive mechanism adapted to displace the movable pressure plate along a second direction.

[0037] Beneficial effects: By setting a driving structure on the moving pressure plate, the speed at which the moving pressure plate presses the pressure block assembly sequentially along the second direction is constant, so that the pressing force on the material is more uniform, which is suitable for improving the success rate of melt molding.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0054] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0055] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0056] A fuse is an important electrical component, mainly used for circuit protection. It provides safety protection for equipment and lines by melting the fuse under overcurrent conditions. It is widely used in industrial electrical equipment, power systems, and household appliances. A fuse provides protection by heating and melting the fuse element under short-circuit or overload conditions. When the current exceeds the rated value, the fuse element heats up rapidly and melts within a preset time, thereby cutting off the circuit and avoiding equipment damage or fire risks.

[0057] The forging technology of the melt directly determines the performance of the fuse. The melt is usually made of a deformable sheet of conductive metal. In related technologies, the forging process of melt forming is usually carried out in segments, which results in poor dimensional accuracy of segmented forging. To obtain a multi-segment melt, multiple processing is required, and the melt shape consistency is poor, resulting in low melt production efficiency.

[0058] This invention provides a melt forming mold. During forging, the material is placed in a material receiving cavity. The mold body is formed with a stamping groove, which is opened on one side of the material receiving cavity along a first direction close to the mold body. A guide groove extending along the first direction is opened on the other side. By setting the guide groove extending along the first direction, the pressing block assembly is accommodated in the guide groove and is suitable for moving relative to the mold body along the first direction. The pressing block assembly includes multiple pressing block units. By arranging the pressing block units along a second direction, the melt can be formed into multiple segments of different shapes according to the number of pressing block units. The pressing block unit includes a pressing part and a stamping part. During forging, the stamping part passes through the material receiving cavity and abuts against the material. The pressing part is moved along the second direction by a movable pressure plate and presses sequentially. Moving and pressing sequentially can avoid the material being subjected to excessive deformation due to simultaneous force, which could lead to tearing or other failure states. The external force applied by the movable pressure plate is transmitted to the pressing part and then to the stamping part, which causes the material to deform by acting on the stamping groove, ultimately obtaining the target melt, realizing the one-time forming of multiple melt segments.

[0059] The following is combined Figures 1 to 9 The following describes embodiments of the present invention.

[0060] According to an embodiment of the present invention, a melt forming mold is provided, comprising:

[0061] The mold body 1 has a stamping groove 11 formed therein, and a material receiving cavity 12 suitable for receiving materials is provided, and a guide groove 13 extending along the first direction is provided.

[0062] The pressing assembly 2 is at least partially disposed within the guide groove 13 and adapted to move relative to the mold body 1 along a first direction. The pressing assembly 2 is disposed along the first direction on the side of the material receiving cavity 12 away from the stamping groove 11. The pressing assembly 2 includes a plurality of pressing units 21, which are arranged along a second direction. The pressing unit 21 includes a stamping part and a pressing part. The stamping part is located at the end of the pressing unit 21 along the first direction near the stamping groove 11 and the shape of the stamping part matches that of the stamping groove 11. The pressing part is located at the end of the pressing unit 21 along the first direction away from the stamping part.

[0063] The movable pressure plate 3 is adapted to move along the second direction and press the pressing part of the pressure block unit 21 in sequence, so that the pressure block unit 21 moves along the first direction to press the material.

[0064] The mold body 1 is formed with a stamping groove 11, which is suitable for material forming. The material receiving cavity 12 can accommodate the material. At the same time, the guide groove 13 extending along the first direction provides structural support for the stamping structure that cooperates with the stamping groove 11. The pressing block assembly 2 is suitable for pressing the material into the stamping groove 11. It is provided with multiple pressing block units 21, which are arranged along the second direction. The stamping groove 11 extends along the second direction. The pressing block unit 21 has a stamping part at one end near the stamping groove 11 along the first direction. The stamping part matches the shape of the stamping groove 11 and is suitable for pressing the material. The movable pressure plate 3 moves along the second direction and presses the pressing part of the pressing block unit 21 in sequence, providing a force for the pressing block assembly 2 to move along the first direction to press the material.

[0065] When forging begins, the movable pressure plate 3 moves along the second direction to press the pressure block unit 21 in sequence. The pressure block unit 21 is displaced along the first direction under force, and the force is transmitted to the stamping part through the pressing part. Then the stamping part presses the material into the stamping groove 11, so that the material is formed in sequence along the second direction.

[0066] In some embodiments, combined with Figure 6 As shown, the stamping groove 11 includes:

[0067] The first stamping groove 111, the second stamping groove 112, and the third stamping groove 113 are arranged adjacent to each other along the second direction. The third stamping groove 113 is disposed at at least one end of the stamping groove 11 along the second direction. The number of the first stamping groove 111 and the second stamping groove 112 is multiple.

[0068] The pressing unit 21 includes: a first pressing block 211 and a second pressing block 212; the first pressing block 211 has a first pressing portion 2111 at one end near the pressing groove 11 along the first direction, and the second pressing block 212 has a second pressing portion 2121 at one end near the pressing groove 11 along the first direction, and the first pressing block 211 and the second pressing block 212 are connected in a cooperating manner; the first pressing portion 2111 and the second pressing portion 2121 are respectively matched with the shapes of the first pressing groove 111 and the second pressing groove 112;

[0069] The pressing block assembly 2 further includes a third pressing block 22, which is disposed at at least one end of the pressing block assembly 2 along the second direction. The end of the third pressing block 22 near the stamping groove 11 along the first direction has a third stamping portion 221. The shape of the third stamping portion 221 matches that of the third stamping groove 113.

[0070] During the forging process, the required melt may have various shapes, and the stamping groove 11 needs to match the melt. By setting a first stamping groove 111, a second stamping groove 112, and a third stamping groove 113, the stamping groove 11 is divided into three different types of first stamping grooves 111, second stamping grooves 112, and third stamping grooves 113. At the same time, the pressing unit 21 includes a first pressing block 211 and a second pressing block 212. The first pressing block 211 and the second pressing block 212 have a first stamping part 2111 and a second stamping part 2121 at one end along the first direction near the stamping groove 11. The first stamping groove 111 and the second stamping groove 112 correspond and match the first stamping part 2111 and the second stamping part 2121. The third pressing block 22 is provided at least one end of the pressing block assembly 2 along the second direction. The end of the third pressing block 22 near the stamping groove 11 along the first direction has a third stamping part 221, so that the third stamping part 221 corresponds and matches the third stamping groove 113. This is beneficial to obtain different melt shapes according to work needs when forging melt, and also meets the technical requirement that multiple melts can be forged at one time.

[0071] Furthermore, the first stamping part 2111, the second stamping part 2121 and the third stamping part 221 are integrally formed with the first pressing block 211, the second pressing block 212 and the third pressing block 22, respectively.

[0072] As one implementation, multiple first stamping grooves 111, second stamping grooves 112 and third stamping grooves 113 are provided and have different shapes to meet the forging and forming requirements of different melts;

[0073] Furthermore, the first stamping part 2111 is adapted to stamp the material into a V-shaped structure, the second stamping part 2121 is adapted to stamp the material into a flat planar structure, and the third stamping part 221 is adapted to stamp the material into a right-angled structure. The first stamping groove 111 is a V-shaped groove adapted to the first stamping part 2111, and the second stamping groove 112 is a flat planar structure adapted to the second stamping part 2121. The first stamping groove 111 and the second stamping groove 112 are arranged adjacent to each other. The third stamping groove 113 is a right-angled edge structure, such as a through groove with a square cross-section, adapted to press the material from the initial state into the third stamping groove 113 by the third stamping part 221. The inner wall of the third stamping groove 113 near the material is perpendicular to the plane where the stamping groove 11 is located, forming a right-angled edge structure. The melt obtained by stamping has a right-angled fold at at least one end.

[0074] In some embodiments, combined with Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the guide groove includes:

[0075] The snap-fit ​​groove 131 extends along the first direction and is disposed on the inner wall of the mold body 1 near the guide groove 13;

[0076] The first pressing block 211 engages with the locking groove 131, and a locking space is formed between adjacent first pressing blocks. The locking space is suitable for accommodating the second pressing block 212.

[0077] The guide groove 13 is suitable for accommodating part of the pressing block assembly 2, and the corresponding snap-fit ​​groove 131 is suitable for accommodating the first pressing block 211. By arranging the first pressing block 211 and the second pressing block 212 adjacently, a snap-fit ​​space is formed between the adjacent first pressing blocks 211. The snap-fit ​​space is suitable for accommodating the second pressing block 212, providing structural support for the elastic connection between the pressing block assembly 2 and the mold body 1. The connection structure between the pressing block unit 21 and the guide groove 13 is simple and convenient for disassembly and installation.

[0078] As one implementation, the snap-fit ​​slots 131 are arranged in pairs, and the length of the first pressing block 211 along the third direction is exactly matched with the distance between the paired snap-fit ​​slots 131. The second pressing block 212 is embedded between the adjacent first pressing blocks 211 and is plugged into the adjacent first pressing blocks 211.

[0079] Furthermore, the first pressing block 211 is provided with a first protrusion 2112 in the opposite direction to the moving pressing plate 3; the second pressing block 212 is provided with a second protrusion 2123 in the moving pressing plate 3. The first protrusion 2112 is located relatively close to the moving pressing plate 3, and the second protrusion 2123 is located relatively far away from the moving pressing plate 3. The first protrusion 2112 and the second protrusion 2123 abut against each other. By setting the first protrusion 2112 and the second protrusion 2123, when the second pressing block 212 is subjected to a force and rebounds, the first pressing block 211 is subjected to a force from the second pressing block 212 in the rebound direction. The second protrusion 2123 is closer to the stamping groove 11 in the rebound direction relative to the first protrusion 2112, so that the second protrusion 2123 can abut against the first protrusion 2112 during the reset process of the second pressing block 212, thereby driving the first pressing block 211 to reset. The third protrusion 222 has the same structure as the second protrusion 2123.

[0080] Furthermore, the first pressing block 211, the first protrusion 2112, the second pressing block 212, and the second protrusion 2123 are all integrally formed.

[0081] In some embodiments, combined with Figure 6 and Figure 7 As shown, part of the pressing block assembly 2 moves relative to the mold body 1 in the first direction within the guide groove 13 and is elastically connected to the mold body 1. The pressing block assembly 2 generates displacement in the first direction by external force pressing in the first direction, which varies with the magnitude of the external force. After the moving pressure plate 3 moves in the second direction and presses the pressing block assembly 2 in sequence, the pressing block assembly 2 is elastically connected to the mold body 1, so that after the pressing block assembly 2 is displaced in the first direction by external force, the pressing block assembly 2 can be reset after the external force disappears, which facilitates repeated forging, improves work efficiency, and saves time and costs.

[0082] As one implementation, the elastic element in the elastic connection is a spring 23. The specific connection structure is as follows: the guide groove 13 includes a first snap-fit ​​boss 132, which is disposed at one end away from the movable pressure plate 3 along the first direction and is arranged adjacent to the snap-fit ​​groove 131 along the second direction; the second pressure block 212 includes a second snap-fit ​​boss 2122, at least one of which is disposed at one end of the second pressure block 212 along the third direction, and the second snap-fit ​​boss 2122 and the first snap-fit ​​boss 132 form a snap-fit ​​cavity in the first direction; the pressure block assembly 2 also includes a spring 23, which is disposed in the snap-fit ​​cavity along the first direction, and the two ends of the spring 23 abut against the first snap-fit ​​boss 132 and the second snap-fit ​​boss 2122 respectively.

[0083] Furthermore, the first snap-fit ​​boss 132 and the guide groove 13, and the second snap-fit ​​boss 2122 and the second pressure block 212 are all integrally formed.

[0084] The guide groove has a first snap-fit ​​boss, and the second pressure block has a second snap-fit ​​boss. The first snap-fit ​​boss and the second snap-fit ​​boss correspond to each other along the first direction to form a snap-fit ​​cavity. The snap-fit ​​cavity is suitable for accommodating a spring, so that the pressure block assembly and the mold body are elastically connected. By setting the spring in the snap-fit ​​cavity, the pressure block assembly can automatically complete the reset after forging.

[0085] In some embodiments, combined with Figure 1 As shown, a cover plate 4 is provided on the movable pressure plate 3 away from the movable pressure plate 3 along the first direction, and the cover plate 4 is slidably connected to the movable pressure plate 3 along the second direction; by setting the cover plate 4 to transmit the force to the movable pressure plate 3 along the first direction, the movable pressure plate 3 has the force to press the pressure block assembly 2 along the first direction, thereby achieving the forging effect of the pressure block assembly 2.

[0086] Optionally, the first direction and the second direction are not parallel, and the third direction is perpendicular to the first direction and the second direction respectively. In this scheme, it is preferable that the first direction and the second direction are perpendicular to each other.

[0087] In some embodiments, combined with Figure 5 As shown, the mold body 1 includes:

[0088] The first mold 14 and the second mold 15 are used to accommodate the pressing block assembly 2. The second mold 15 is provided with a stamping groove 11 on the side near the pressing block assembly 2. The first mold 14 and the second mold 15 are detachably connected. By splitting the mold body 1 into the first mold 14 and the second mold 15, it is more convenient to install and disassemble the mold body 1. The stamping groove 11 and the material receiving cavity 12 inside the mold body 1, which are not conducive to the overall processing, can be processed more simply and effectively, thereby improving the processing efficiency of the mold body 1.

[0089] In some embodiments, combined with Figure 1 As shown, the movable pressure plate 3 is equipped with a driving mechanism, which is adapted to move the movable pressure plate 3 along the second direction. By setting the driving structure on the movable pressure plate 3, the speed at which the movable pressure plate 3 presses the pressure block assembly 2 in sequence along the second direction is constant, so that the pressing pressure on the material is more uniform, which is suitable for improving the success rate of melt molding.
