Description

Technical Field

[0001] This invention belongs to the technical field of diamond cutting tool manufacturing equipment, specifically relating to a diamond cutting tool die casting mold. Background Technology

[0002] Diamond cutting tools, as core components of modern high-efficiency precision machining, are technologically developed based on the exceptional properties of diamond, the hardest known natural substance. Traditional cemented carbide tools face bottlenecks such as rapid wear, low efficiency, and poor machining quality when machining superhard and wear-resistant materials. Diamond, with its unparalleled hardness, extremely high thermal conductivity, excellent wear resistance, and chemical stability, has become an ideal material for manufacturing superhard cutting tools. Since the mid-20th century, breakthroughs in high-temperature, high-pressure, and chemical vapor deposition techniques for synthesizing synthetic diamonds, especially the emergence of diamond micron powder and polycrystalline diamond, have laid the foundation for the large-scale application of diamond cutting tools. The core technology of diamond cutting tools lies in forming a composite structure with sharp cutting edges by using specific processes or cemented carbide substrates to form diamond particles.

[0003] The die-casting mold technology for diamond cutting tools is mainly used in the production and manufacturing of diamond cutting tools. Diamond cutting tools are made by mixing diamond particles with metal powder and then cold-pressing and hot-pressing sintering processes. The die-casting mold plays a key role in this process, which can shape the mixture into the required cutting tool shape. Traditional molds have complex structures and require manual stacking, resulting in low production efficiency, difficulty for operators to take out and transport the cutting tools, and the cutting tools are prone to breakage and inconsistent quality. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a die-casting mold for diamond cutting tools.

[0005] The technical solution adopted to solve the above technical problems is: a diamond tool die casting mold, including an outer mold, a first inner mold slidably connected between the two short ends of the inner side of the outer mold, a third inner mold slidably connected to the two long ends of the inner side of the outer mold, a second inner mold meshing between the two third inner molds and the first inner mold, and auxiliary clamping components respectively installed in the middle of the four sides of the outer mold.

[0006] Furthermore, the first inner mold includes two short clamping plates, which are slidably attached to the inner side of the outer mold. A plurality of first long clamping blocks and first flat clamping blocks are arranged between the two short clamping plates, and the plurality of first long clamping blocks and first flat clamping blocks are arranged in two rows of cross array.

[0007] The above technical solution can effectively increase the filling density of the diamond particle and metal powder mixture in the first inner mold, improve the forming effect of the cutter head, and at the same time, the first long clamping block and the first flat clamping block arranged in two rows of cross arrays can provide a uniform pressure distribution during the die casting process, ensuring that the density of each part of the cutter head is uniform, further improving the overall quality of the cutter head, making the first inner mold more stable when sliding, reducing the risk of mold deformation or damage, and extending the service life of the mold.

[0008] Furthermore, the second inner mold includes a central insert plate, and several central clamping blocks are respectively arranged on the central portions of both sides of the central insert plate.

[0009] The above technical solution can effectively adjust the distribution of the diamond particle and metal powder mixture in the second inner mold, optimize the filling effect, and make several middle clamping blocks evenly distributed on both sides of the middle insert plate so that the mixture is subjected to more balanced extrusion pressure during the die casting process, thereby improving the density and uniformity of the cutter head. In addition, the design of the middle clamping blocks also enhances the structural strength of the second inner mold, enabling it to maintain a stable shape in the high pressure casting environment and avoid cutter head defects caused by mold deformation. This fine structural design not only improves the quality of the cutter head, but also ensures the long-term durability of the mold.

[0010] Furthermore, the third inner mold includes a long clamping plate, and a second long clamping block and a second flat clamping block are rotatably connected to the top of the long clamping plate, and a plurality of the second long clamping blocks and the second flat clamping blocks are arranged in a cross array.

[0011] The above technical solution can further optimize the filling state of the diamond particle and metal powder mixture in the third inner mold, ensuring that the mixture is subjected to more uniform and stable extrusion pressure during the die casting process. The cross-array arrangement of several second long clamping blocks and second flat clamping blocks not only improves the filling density of the mixture, but also enhances the overall strength and wear resistance of the cutting head. At the same time, this structural design allows the third inner mold to better adapt to the high-pressure environment during the die casting process, reducing the possibility of mold deformation or damage, further extending the service life of the mold, thereby reducing production costs and improving production efficiency.

[0012] Furthermore, a U-shaped groove and a U-shaped annular groove are respectively provided at the contact points between the first long clamping block and the first flat clamping block. A round-headed protrusion is provided on the inner side of the U-shaped groove. The U-shaped annular groove is located in the groove between the U-shaped groove and the round-headed protrusion. The U-shaped annular groove is slidably connected to the U-shaped groove and the round-headed protrusion. The bottom surfaces of the first long clamping block and the first flat clamping block are flush with each other. The notch formed at the top of the first long clamping block and the first flat clamping block is slidably engaged with the bottom of the middle clamping block.

[0013] The above technical solutions can further enhance the connection stability between the first long clamping block and the first flat clamping block, while improving their fitting accuracy with the middle clamping block. The design of the U-shaped groove and U-shaped annular groove, as well as the setting of the round-headed convex plate, not only provide a more reliable sliding connection structure for the first long clamping block and the first flat clamping block, but also ensure their stable fit under different pressure conditions, avoiding the quality problems of the cutting head caused by mold deformation. This allows the mold to better adapt to various complex process conditions during the die casting process, further improving the production quality and efficiency of diamond cutting heads.

[0014] Furthermore, several first sliding grooves are provided in the middle of both sides of the middle insert plate, and the several first sliding grooves are all located on the same plane. A plug is slidably connected to the inner side of the first sliding groove. The upper and lower ends of the plug are respectively fixedly connected to the first elastic sheet. A threaded knob is rotatably threaded to the end of the plug away from the middle insert plate.

[0015] The above technical solution enables effective adjustment and fixation of the center insert plate position. The first sliding groove allows the insert pin to slide flexibly within the same plane, thus adapting to the die-casting requirements of diamond cutter heads of different sizes. The introduction of the first elastic plate not only provides stable support for the insert pin but also acts as a buffer during the insertion pin's sliding process, protecting the mold structure from damage. The threaded knob design allows users to precisely adjust the position of the center clamping block according to actual needs and ensure the stability of the center clamping block during the die-casting process by rotating and locking it. This structural design not only improves the versatility and flexibility of the mold but also provides a strong guarantee for the precise die-casting of diamond cutter heads.

[0016] Furthermore, a second sliding groove is provided in the middle of the middle clamping block, a sliding sleeve is slidably connected inside the second sliding groove, a second elastic piece is provided between the inner side of the second sliding groove and the outer side of the sliding sleeve, the inner side of the sliding sleeve is slidably connected to the insertion post, and the end of the sliding sleeve away from the middle insertion plate is rotatably connected to the threaded knob through it, and the top of the middle clamping block is slidably engaged with the notch formed between the second long clamping block and the second flat clamping block.

[0017] Through the above technical solution, the design of the second sliding groove and the sliding sleeve allows the sliding sleeve to slide freely within the second sliding groove. This design not only increases the flexibility of the mold when adjusting the position of the diamond cutter head, but also provides necessary support and buffer for the sliding sleeve through the setting of the second elastic plate, effectively avoiding possible damage to the mold during the adjustment process. At the same time, the sliding connection between the sliding sleeve and the insert ensures the stability and accuracy of the insert during the adjustment process. The through-rotation connection between the end of the sliding sleeve away from the middle insert plate and the threaded knob provides users with an intuitive and easy-to-operate adjustment method, allowing users to easily adjust the position of the sliding sleeve according to actual needs and lock it by rotating the threaded knob, ensuring the stability and reliability of the mold during the die-casting process. In addition, the notched sliding engagement design formed between the top of the middle clamping block and the second long clamping block and the second flat clamping block further enhances the stability and load-bearing capacity of the mold structure, providing a more solid guarantee for the precise die-casting of the diamond cutter head.

[0018] Furthermore, the top of the long clamping plate is rotatably connected to several rotating plates, which are evenly arranged in an array along the top edge of the long clamping plate. A third sliding groove is provided at the end of the rotating plate away from the long clamping plate. The second long clamping block and the second flat clamping block are provided with notches at the ends near the long clamping plate. A fixed sliding rod is fixedly connected to the inside of the notch. The inside of the notch is rotatably connected to the rotating plate, and the fixed sliding rod is slidably connected to the inside of the third sliding groove.

[0019] Through the above technical solution, the rotating connection design between the rotating plate and the long clamping plate gives the rotating plate a certain degree of freedom of movement, making the second long clamping block and the second flat clamping block more flexible in adjusting their positions, thereby adapting to the die-casting requirements of different diamond cutting heads. At the same time, the sliding connection design between the third slide groove and the fixed slide rod not only ensures the stability and accuracy of the rotating plate in the adjustment process, but also effectively reduces the resistance and wear in the adjustment process through sliding friction, extending the service life of the mold. In addition, the design of the rotating plate being evenly arrayed along the top edge of the long clamping plate makes the mold more balanced and stable when adjusting the position of the diamond cutting head, avoiding the problem of mold deformation or damage caused by uneven force.

[0020] Furthermore, the outer mold includes a square frame, with an extension plate fixedly connected to the upper and lower ends of the square frame, and a reinforcing rib fixedly connected to the surface of the square frame. A threaded hole is provided in the middle of the reinforcing rib, and a hexagonal bolt is threaded through the inner side of the threaded hole.

[0021] Through the above technical solutions, the square frame design enhances the overall structural strength of the mold, enabling it to withstand greater die-casting pressure and ensuring the forming quality of the diamond cutting head. The extension plate not only increases the contact area between the mold and the die-casting machine, improving the stability of the mold during the die-casting process, but also facilitates the rapid installation and disassembly of the mold, improving production efficiency. The addition of reinforcing ribs further strengthens the structure of the square frame, effectively preventing the mold from deforming under high pressure and ensuring product precision. The combination of threaded holes and hexagonal bolts provides a simple and reliable connection method, allowing all parts of the mold to be tightly connected, avoiding quality problems caused by mold loosening during the die-casting process. This not only improves the durability and stability of the mold but also helps to improve the forming quality and production efficiency of the product.

[0022] Furthermore, the auxiliary clamping assembly includes a fixed cover plate, a mounting post fixedly connected to the middle of the fixed cover plate, a push plate slidably connected through the middle of the mounting post, pull plates rotatably connected to the upper and lower ends of the push plate, a pressing block rotatably connected to the end of the two pull plates away from the push plate, a pressing block slidably connected through the surface of the outer extension plate at the end away from the pull plate, a limiting sleeve slidably connected through the end of the mounting post away from the fixed cover plate, the limiting sleeve slidably connected through the square frame, an auxiliary clamping plate fixedly connected to the through end of the limiting sleeve, and a spring provided between the limiting sleeve and the push plate.

[0023] Through the above technical solution, the design of the fixed cover plate provides a stable installation base for the auxiliary clamping assembly. The mounting column serves as a support structure for the push plate and pull plate, ensuring the stability of the entire assembly. The push plate is slidably connected to the mounting column, enabling it to move smoothly under force, thereby driving the pull plate to move. The rotational connection between the pull plate and the push plate, as well as the rotational connection between the pull plate and the pressing block, together constitute a flexible transmission mechanism, allowing the pressing block to slide along the surface of the outer plate when the push plate moves, generating the required clamping. The design of the limiting sleeve not only restricts the movement range of the push plate, but also ensures the stability of the auxiliary clamping plate during the clamping process through its through-sliding connection with the square frame. As the part that directly acts on the diamond cutter head die-casting mold, the stability and clamping force of the auxiliary clamping plate directly affect the molding quality of the product. The spring plays a role in buffering and resetting. When the external force disappears, the spring can push the push plate to reset, thereby causing the pressing block and the auxiliary clamping plate to loosen, facilitating the opening of the mold and the removal of the cutter head.

[0024] The beneficial effects of this invention are as follows: 1. This invention, by incorporating multiple sets of auxiliary clamping components, enables multi-point clamping of the diamond cutting tool die-casting mold, improving the mold's stability during the die-casting process. The multiple sets of auxiliary clamping components are evenly distributed around the square frame, ensuring uniform force distribution on the mold and preventing deformation or damage caused by excessive localized force. Simultaneously, this multi-point clamping design effectively prevents displacement or loosening of the diamond cutting tool during die-casting, thus guaranteeing the product's molding accuracy and quality. Furthermore, the auxiliary clamping components have a simple and practical structural design, are easy to install and disassemble, facilitate mold maintenance and replacement, reduce production costs, and improve production efficiency.

[0025] 2. This invention achieves efficient, precise, and stable production of diamond tool tip die-casting molds by employing a modular, integrated inner mold. The modular design allows for flexible and rapid assembly of the various parts of the inner mold. This design also facilitates mold maintenance and replacement, reduces production costs, and improves production efficiency. During the die-casting process, the modular inner mold provides uniform and stable extrusion pressure, ensuring that the diamond particles and metal powder mixture are fully filled and tightly bonded, thereby producing diamond tool tips with high hardness, high wear resistance, and excellent cutting performance. Furthermore, the modular inner mold enhances the structural strength of the mold, maintaining a stable shape under high-pressure casting conditions and avoiding tool tip defects caused by mold deformation, further improving the production quality and efficiency of diamond tool tips.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] like Figures 1 to 12 As shown, this embodiment of a diamond tool tip die-casting mold includes an outer mold 1, a first inner mold 2 slidably connected between the two short ends of the inner side of the outer mold 1, a third inner mold 4 slidably connected to the two long ends of the inner side of the outer mold 1, a second inner mold 3 meshing between the two third inner molds 4 and the first inner mold 2, and auxiliary clamping components 5 respectively installed in the middle of the four sides of the outer mold 1. By adopting the design of modular splicing inner molds and auxiliary clamping components 5, efficient, precise and stable production of diamond tool tip die-casting molds is achieved, improving the molding quality and production efficiency of products and reducing production costs.

[0030] like Figures 1 to 3As shown, the outer mold 1 includes a square frame 101. The square frame 101 serves as the main structure of the mold. Its robust design can withstand greater die-casting pressure, ensuring the precise forming of the diamond cutting head. Extended plates 102 are fixedly connected to the upper and lower ends of the square frame 101, respectively. The extension plates 102 not only increase the contact area between the mold and the die-casting machine, improving the stability of the mold during die-casting, but also facilitate the quick installation and disassembly of the mold, thereby improving production efficiency. Reinforcing ribs 103 are fixedly connected to the surface of the square frame 101. A threaded hole 104 is provided in the middle of the reinforcing rib 103. The addition of the reinforcing rib 103 further strengthens the structure of the square frame 101, effectively preventing the mold from deforming under high pressure, and ensuring the precision and consistency of the product. A hexagonal bolt 105 is threaded through the inner side of the threaded hole 104.

[0031] like Figures 4 to 6 As shown, the first inner mold 2 includes two short clamping plates 201, which slide and fit against the inner side of the outer mold 1 respectively. Between the two short clamping plates 201, there are several first long clamping blocks 202 and first flat clamping blocks 203. The several first long clamping blocks 202 and first flat clamping blocks 203 are arranged in two rows of cross array. By arranging them in a cross array, the pressure during the die casting process is effectively dispersed, avoiding mold damage caused by excessive local stress. At the same time, the alternating arrangement of the first long clamping blocks 202 and first flat clamping blocks 203 also increases the filling density inside the mold, ensuring that the diamond particles and metal powder mixture can be fully filled and tightly bonded, thereby improving the hardness and wear resistance of the diamond cutting head.

[0032] like Figures 5 to 6 As shown, a U-shaped groove 204 and a U-shaped annular groove 205 are respectively provided at the contact points of the first long clamping block 202 and the first flat clamping block 203. A round-headed protrusion 206 is provided on the inner side of the U-shaped groove 204. The U-shaped annular groove 205 is located in the groove between the U-shaped groove 204 and the round-headed protrusion 206. The U-shaped annular groove 205 is slidably connected to the U-shaped groove 204 and the round-headed protrusion 206 respectively. This not only provides a more reliable sliding connection structure for the first long clamping block 202 and the first flat clamping block 203, but also ensures their stable contact under different pressure conditions. It avoids the quality problem of the cutting head caused by mold deformation, so that the mold can better adapt to various complex process conditions during die casting. The bottom surfaces of the first long clamping block 202 and the first flat clamping block 203 are flush with each other. The notch formed at the top of the first long clamping block 202 and the first flat clamping block 203 slides and engages with the bottom of the middle clamping block 302, further enhancing the stability and load-bearing capacity of the mold structure.

[0033] like Figures 7 to 10As shown, the second inner mold 3 includes a central insert plate 301. Several central clamping blocks 302 are respectively arranged in the middle of both sides of the central insert plate 301. Several first sliding grooves 303 are arranged in the middle of both sides of the central insert plate 301. The several first sliding grooves 303 are all located on the same plane. Inserting posts 304 are slidably connected to the inner side of the first sliding grooves 303. First elastic plates 306 are fixedly connected to the upper and lower ends of the inserting posts 304 located in the first sliding grooves 303. A threaded knob 305 is rotatably threaded to the end of the inserting post 304 away from the central insert plate 301. The design of the threaded knob 305 allows users to precisely adjust the position of the central clamping blocks 302 according to actual needs, and lock them by rotation to ensure the stability of the central clamping blocks 302 in the die-casting process. This structural design not only improves the versatility and flexibility of the mold, but also provides a strong guarantee for the precise die-casting of diamond cutting heads.

[0034] like Figures 7 to 10 As shown, a second sliding groove 308 is provided in the middle of the middle clamping block 302. A sliding sleeve 307 is slidably connected inside the second sliding groove 308. A second elastic piece 309 is provided between the inner side of the second sliding groove 308 and the outer side of the sliding sleeve 307. The inner side of the sliding sleeve 307 is slidably connected to the insert post 304. The end of the sliding sleeve 307 away from the middle insert plate 301 is rotatably connected to the threaded knob 305. The notch formed between the top of the middle clamping block 302 and the second long clamping block 402 and the second flat clamping block 403 is slidably engaged. The rotational connection design between the rotating plate 404 and the long clamping plate 401, and the sliding connection design between the third sliding groove 405 and the fixed sliding rod 407, make the second long clamping block 402 and the second flat clamping block 403 more flexible and accurate when adjusting their positions, thereby adapting to the die-casting requirements of different diamond cutting heads.

[0035] like Figure 11 As shown, the third inner mold 4 includes a long clamping plate 401. The top of the long clamping plate 401 is rotatably connected to a second long clamping block 402 and a second flat clamping block 403. Several second long clamping blocks 402 and second flat clamping blocks 403 are arranged in a cross array. The first long clamping block 202 and the first flat clamping block 203 in the first inner mold 2 are similar. The cross array arrangement of the second long clamping blocks 402 and the second flat clamping blocks 403 not only effectively disperses the pressure during the die casting process and improves the load-bearing capacity of the mold, but also ensures the uniform distribution and tight bonding of the diamond particles and metal powder mixture inside the mold, thereby further improving the hardness and wear resistance of the diamond cutting head.

[0036] like Figure 11As shown, a number of rotating plates 404 are rotatably connected to the top of the long clamping plate 401. The rotating plates 404 are evenly arranged in an array along the top edge of the long clamping plate 401. A third sliding groove 405 is provided at the end of the rotating plate 404 away from the long clamping plate 401. A notch 406 is provided at the end of the second long clamping block 402 and the second flat clamping block 403 near the long clamping plate 401. A fixed sliding rod 407 is fixedly connected to the inside of the notch 406. The inside of the notch 406 is rotatably connected to the rotating plate 404. The fixed sliding rod 407 is slidably connected to the inside of the third sliding groove 405.

[0037] like Figure 12 As shown, the auxiliary clamping assembly 5 includes a fixed cover plate 501, with a mounting post 506 fixedly connected to the middle of the fixed cover plate 501. The fixed cover plate 501 provides a stable foundation for the entire assembly, while the mounting post 506 serves as the core support structure, ensuring the stable and precise operation of components such as the push plate 504, pull plate 508, and pressing block 502. The push plate 504 is slidably connected through the middle of the mounting post 506, and pull plates 508 are rotatably connected to the upper and lower ends of the push plate 504. A pressing block 502 is rotatably connected to the end of the two pull plates 508 away from the push plate 504. The end of the pressing block 502 away from the pull plate 508 is slidably connected through the surface of the extension plate 102. The end of the mounting post 506 away from the fixed cover plate 501... A through-sliding connection is provided with a limiting sleeve 507, which is slidably connected to the square frame 101. An auxiliary clamping plate 503 is fixedly connected to the through end of the limiting sleeve 507. A spring 505 is provided between the limiting sleeve 507 and the push plate 504. The spring 505 plays a crucial role in buffering and resetting. When an external force is applied to the push plate 504, the spring 505 can absorb part of the impact force, thereby protecting the mold from damage. When the external force disappears, the spring 505 can push the push plate 504 to reset, causing the pressing block 502 and the auxiliary clamping plate 503 to loosen, facilitating the opening of the mold and the removal of the cutting head. This not only improves the ease of operation of the mold but also helps to extend the service life of the mold.

[0038] The working principle of this embodiment is as follows: In use, the diamond particle and metal powder mixture is first placed in the mold cavity between the first inner mold 2, the second inner mold 3, and the third inner mold 4 to ensure that the diamond particle and metal powder mixture is evenly distributed in the mold cavity. By rotating the threaded knob 305, the position of the middle clamping block 302 can be adjusted, thereby adjusting the overall structure of the second inner mold 3 to ensure that it is tightly engaged with the first inner mold 2 and the third inner mold 4, ensuring the stability and load-bearing capacity of the mold during the die casting process. At the same time, the rotating connection design between the rotating plate 404 and the long clamping plate 401, and the sliding connection design between the third slide groove 405 and the fixed slide rod 407, make the second long clamping block 402 and the second flat clamping block 403 more flexible and accurate in adjusting their positions, thereby adapting to the die casting requirements of different diamond cutting heads.

[0039] After the mold adjustment is completed, during the die casting process, the auxiliary clamping assembly 5 clamps the mold. Specifically, the press presses the pressing block 502, causing the push plate 504 to slide on the mounting post 506, and driving the pull plate 508 and the pressing block 502 to move together until the auxiliary clamping plate 503 is tightly attached to the outer surface of the mold. At this time, the spring 505 is in a compressed state, providing a continuous clamping force for the mold. During the die casting process, the auxiliary clamping assembly 5 can ensure the stability of the mold and prevent the diamond cutter head from shifting or loosening, thereby ensuring the molding accuracy and quality of the product.

[0040] After die casting is completed, release the pressing block 502, and the spring 505 pushes the push plate 504 to reset, thereby causing the pressing block 502 and the auxiliary clamping plate 503 to be released, which facilitates the opening of the mold and the removal of the cutting head. At this time, the various parts of the mold can be quickly disassembled and replaced by adjusting the position of the threaded knob 305 and the rotating plate 404 in order to carry out the next round of production.

[0041] In summary, the diamond cutting tool die-casting mold of the present invention, through the design of a modularly spliced ​​inner mold and auxiliary clamping component 5, achieves efficient, precise and stable production of diamond cutting tool die-casting molds, improves product molding quality and production efficiency, reduces production costs, and has broad application prospects and market value.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
