Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of diamond blade manufacturing equipment, and particularly relates to a diamond tool bit die casting die. BACKGROUND

[0002] As a core tool component of modern high-efficiency precision machining, the diamond tool bit is rooted in the excellent performance of diamond, the hardest material known in nature. When machining superhard and wear-resistant materials, traditional hard alloy cutters face the bottleneck of fast wear, low efficiency and poor machining quality. Diamond becomes an ideal material for manufacturing superhard cutters due to its unparalleled hardness, extremely high thermal conductivity, excellent wear resistance and chemical stability. Since the middle of the 20th century, with the breakthrough of high-temperature and high-pressure and chemical vapor deposition synthetic diamond technology, especially the emergence of diamond micro powder and polycrystalline diamond, the large-scale application of diamond tool bits has been laid a foundation. The core technology of diamond tool bit is to form a composite structure with sharp cutting edges on the hard alloy substrate through a specific process.

[0003] The diamond tool bit die casting die technology is mainly used for the production and manufacturing of diamond tool bits. The diamond tool bit is made by mixing diamond particles and metal powder, and then cold pressing and sintering. The die casting die plays a key role in this process and can shape the mixture into the required tool bit shape. The traditional die structure is complex, and manual stacking is required, which is low in production efficiency and not conducive to the operation personnel to take out and transport the tool bit. Moreover, the tool bit is easy to break and the quality is unstable. SUMMARY

[0004] The technical problem to be solved by the application is to overcome the shortcomings of the prior art and provide a diamond tool bit die casting die.

[0005] The technical scheme adopted to solve the above technical problem is as follows: a diamond tool bit die casting die, comprising an outer die, a first inner die slidingly connected between two short ends on the inner side of the outer die, a third inner die slidingly connected to two long ends on the inner side of the outer die, a second inner die meshingly connected between the two third inner dies and the first inner die, and an auxiliary clamping assembly installed on the middle of each side of the outer die.

[0006] Further, the first inner die comprises two short clamping plates, the two short clamping plates are respectively slidingly attached to the inner side of the outer die, 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 a two-row cross array.

[0007] Through the above technical solution, the filling density of the mixture of diamond particles and metal powder in the first inner mold can be effectively increased, thereby improving the molding effect of the cutter head. At the same time, the two rows of cross-arrayed first long clamps and first flat clamps can provide uniform pressure distribution during the die-casting process, ensuring uniform density of various parts of the cutter head, further improving the overall quality of the cutter head, making the first inner mold more stable during sliding connection, reducing the risk of mold deformation or damage, and extending the service life of the mold.

[0008] Furthermore, the second inner mold includes a middle insert plate, and a plurality of middle clamping blocks are respectively provided in the middle of both sides of the middle insert plate.

[0009] Through the above technical solution, the distribution state of the mixture of diamond particles and metal powder in the second inner mold can be effectively adjusted to optimize the filling effect. Several middle clamps are evenly distributed on both sides of the middle insert plate, so that the mixture is subjected to a more balanced extrusion force during the die-casting process, thereby improving the density and uniformity of the cutter head. In addition, the design of the middle clamps also enhances the structural strength of the second inner mold, allowing it to maintain a stable shape in a high-pressure casting environment, avoiding cutter head defects caused by mold deformation. This sophisticated 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, the top end of which is rotatably connected to a second long clamping block and a second flat clamping block, and a plurality of the second long clamping blocks and the second flat clamping blocks are arranged in a cross array.

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

[0012] Furthermore, a U-shaped groove and a U-shaped ring groove are respectively provided at the joints between the first long clamping block and the first flat clamping block, a round-head convex plate is provided on the inner side of the U-shaped groove, the U-shaped ring groove is located in the groove between the U-shaped groove and the round-head convex plate, the U-shaped ring groove is slidingly connected to the U-shaped groove and the round-head convex plate respectively, the bottom end faces of the first long clamping block and the first flat clamping block are flush with each other, and the notch formed by the top end of the first long clamping block and the first flat clamping block is slidingly engaged with the bottom end of the middle clamping block.

[0013] Through the above technical solution, the connection stability between the first long clamping block and the first flat clamping block can be further enhanced, and at the same time, the matching accuracy between them and the middle clamping block can be improved. The design of the U-shaped groove and the U-shaped ring groove, as well as the setting of the round head 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 states, avoiding the quality problems of the cutter head caused by mold deformation, so that the mold can better adapt to various complex process conditions during the die-casting process, and further improve the production quality and efficiency of diamond cutter heads.

[0014] Furthermore, a plurality of first sliding grooves are provided in the middle of both sides of the middle insert plate, and the plurality of first sliding grooves are all located in the same plane.

The plug-in column is rotatably threadedly connected to a threaded knob at one end away from the middle insert plate.

[0015] Through the above technical solution, the position of the center plug plate can be effectively adjusted and fixed. The setting of the first slide groove enables the plug column to slide flexibly in the same plane, thereby adapting to the die-casting requirements of diamond bits of different sizes. The introduction of the first elastic sheet not only provides a stable support force for the plug column, but also plays a buffering role during the sliding process of the plug column, protecting the mold structure from damage. The design of the threaded knob allows the user to accurately adjust the position of the center clamp according to actual needs, and lock it by rotation to ensure the stability of the center clamp during the die-casting process.

[0017] By the technical scheme, the cooperation of the second sliding groove and the sliding sleeve enables the sliding sleeve to freely slide in the second sliding groove, which not only increases the flexibility of the mold when adjusting the position of the diamond cutter, but also provides necessary support and buffering for the sliding sleeve through the setting of the second elastic sheet, effectively avoiding damage to the mold during adjustment, and meanwhile, the sliding connection of the sliding sleeve and the inserting column ensures the stability and accuracy of the inserting column during adjustment, and the penetrating and rotating connection of the end of the sliding sleeve away from the middle clamping plate and the threaded knob provides an intuitive and easy-to-operate adjustment mode for the user, so that the user can easily adjust the position of the sliding sleeve according to actual needs, and lock through rotating the threaded knob, thereby ensuring the stability and reliability of the mold during die casting, and in addition, the slot sliding engagement design between the top end of the middle clamping block and the second long clamping block and the second flat clamping block further enhances the stability and load capacity of the mold structure, and provides a more solid guarantee for accurate die casting of the diamond cutter.

[0019] Through the above technical scheme, the rotating connection design between the rotating plate and the long clamping plate gives the rotating plate a certain degree of freedom, so that the second long clamping block and the second flat clamping block can be more flexible when adjusting the position, thereby adapting to the die casting needs of different diamond cutters, and meanwhile, the sliding connection design of the third sliding groove and the fixed sliding rod not only ensures the stability and accuracy of the rotating plate during adjustment, but also effectively reduces the resistance and wear during adjustment through sliding friction, thereby prolonging the service life of the mold, and in addition, the design of the rotating plate evenly arrayed along the long clamping plate top end edge enables the mold to be more balanced and stable when adjusting the position of the diamond cutter, thereby avoiding the problems of mold deformation or damage caused by uneven stress.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present 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 only used to explain the present invention and are not intended to limit the present invention.

[0029] like Figures 1 to 12 As shown, a diamond segment die-casting mold of the present embodiment includes an outer mold 1, a first inner mold 2 is slidably connected between the two short ends inside the outer mold 1, and a third inner mold 4 is slidably connected to the two long ends inside the outer mold 1, and a second inner mold 3 is meshed and connected between the two third inner molds 4 and the first inner mold 2, and auxiliary clamping components 5 are respectively installed in the middle of the four outer sides of the outer mold 1. By adopting the design of modular spliced ​​inner molds and auxiliary clamping components 5, efficient, precise and stable production of diamond segment die-casting molds is achieved, the molding quality and production efficiency of the product are improved, and the production cost is reduced.

[0030] like Figures 1 to 3As shown, the outer mold 1 includes a square frame body 101, which is the main structure of the mold, and its solid design can withstand large die casting pressure, ensuring the accurate molding of the diamond tool bit. The outer extension plate 102 is fixedly connected to the upper and lower ends of the square frame body 101. The setting of the outer extension plate 102 not only increases the contact area of the mold and the die casting machine, but also improves the stability of the mold during die casting, and facilitates the quick installation and disassembly of the mold, thereby improving the production efficiency. The square frame body 101 is fixedly connected with a reinforcing rib 103, and the reinforcing rib 103 is provided with a threaded hole 104 in the middle. The addition of the reinforcing rib 103 further strengthens the structure of the square frame body 101, effectively preventing the mold from deforming in a high-pressure environment and ensuring the accuracy and consistency of the product. The hexagonal bolt 105 is threadedly connected to the inner side of the threaded hole 104.

[0031] As shown in Figures 4 to 6 The first inner mold 2 includes two short clamping plates 201, which are respectively in sliding fit with the inner side of the outer mold 1. A plurality of first long clamping blocks 202 and first flat clamping blocks 203 are arranged between the two short clamping plates 201. The plurality of first long clamping blocks 202 and first flat clamping blocks 203 are arranged in two rows of cross arrays. By arranging in the cross array manner, the pressure in the die casting process is effectively dispersed, and the problem of mold damage caused by excessive local stress is avoided. At the same time, the alternating arrangement of the first long clamping blocks 202 and the first flat clamping blocks 203 also increases the filling density inside the mold, ensuring that the mixture of diamond particles and metal powder can be fully filled and tightly combined, thereby improving the hardness and wear resistance of the diamond tool bit.

[0032] As shown in Figures 5 to 6 The first long clamping block 202 and the first flat clamping block 203 are respectively provided with a U-shaped groove 204 and a U-shaped ring groove 205 at the joint. The inner side of the U-shaped groove 204 is provided with a round head protruding plate 206, and the U-shaped ring groove 205 is located in the groove between the U-shaped groove 204 and the round head protruding plate 206. The U-shaped ring groove 205 is respectively in sliding connection with the U-shaped groove 204 and the round head protruding plate 206. Not only does it provide a more reliable sliding connection structure for the first long clamping block 202 and the first flat clamping block 203, but it also ensures their stable fit under different pressure conditions and avoids the problem of tool quality caused by mold deformation. The mold can better adapt to various complex process conditions during the die casting process. The bottom end faces of the first long clamping block 202 and the first flat clamping block 203 are flush with each other, and the missing slot formed by the top ends of the first long clamping block 202 and the first flat clamping block 203 is in sliding engagement with the bottom end of the middle clamping block 302, further enhancing the stability and load-bearing capacity of the mold structure.

[0033] As shown in Figures 7 to 10As shown, the second inner mold 3 includes a middle insert plate 301, and a plurality of middle clamping blocks 302 are arranged on both sides of the middle insert plate 301. A plurality of first sliding grooves 303 are arranged on both sides of the middle insert plate 301, and the first sliding grooves 303 are located in the same plane. An insert column 304 is slidably connected to the inner side of the first sliding groove 303. First elastic sheets 306 are fixedly connected to the upper and lower ends of the insert column 304. A threaded knob 305 is threadedly connected to the end of the insert column 304 away from the middle insert plate 301. The threaded knob 305 allows the user to accurately adjust the position of the middle clamping block 302 according to actual needs and ensures the stability of the middle clamping block 302 during the die casting process by rotating and locking. This structure design not only improves the versatility and flexibility of the mold, but also provides a strong guarantee for the accurate die casting of the diamond tool bit.

[0034] As shown in Figures 7 to 10 The middle clamping block 302 is provided with a second sliding groove 308. A sliding sleeve 307 is slidably connected to the inside of the second sliding groove 308. A second elastic sheet 309 is arranged between the inner side of the second sliding groove 308 and the outer side of the sliding sleeve 307. The sliding sleeve 307 is slidably connected to the insert column 304. The sliding sleeve 307 is rotatably connected to the threaded knob 305 at the end away from the middle insert plate 301. The top end of the middle clamping block 302 is slidably engaged with the gap formed between the second long clamping block 402 and the second flat clamping block 403. The rotating connection between the rotating plate 404 and the long clamping plate 401 and the sliding connection 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 the position, thereby adapting to the die casting needs of different diamond tool bits.

[0035] As shown in Figure 11 The third inner mold 4 includes a long clamping plate 401. The long clamping plate 401 is rotatably connected to the second long clamping block 402 and the second flat clamping block 403 at the top end. A plurality of 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 block 402 and the second flat clamping block 403 not only effectively disperses the pressure during the die casting process, improves the carrying capacity of the mold, but also ensures the uniform distribution and close combination of the mixture of diamond particles and metal powder inside the mold, thereby further improving the hardness and wear resistance of the diamond tool bit.

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

[0037] like Figure 12 As shown, the auxiliary clamping assembly 5 includes a fixed cover plate 501, and a mounting column 506 is fixedly connected to the middle of the fixed cover plate 501. The fixed cover plate 501 provides a stable foundation for the entire assembly, and the mounting column 506 serves as a core supporting structure to ensure that components such as the push plate 504, the pull plate 508 and the pressing block 502 can operate stably and accurately. The middle of the mounting column 506 is slidably connected to the push plate 504, and the upper and lower ends of the push plate 504 are rotatably connected to the pulling plate 508. The two pulling plates 508 are rotatably connected to the pressing block 502 at one end away from the push plate 504, and the pressing block 502 is slidably connected to the surface of the extension plate 102 at one end away from the pulling plate 508. The mounting column 506 is away from the fixed cover plate 501. The limiting sleeve 507 is connected through the sliding connection, and the limiting sleeve 507 is connected to the square frame 101 through the sliding connection. The limiting sleeve 507 is fixedly connected to the auxiliary splint 503 at the through end. A spring 505 is arranged between the limiting sleeve 507 and the push plate 504. The setting of the spring 505 plays a key buffering and resetting role. When external force acts on 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, driving the pressing block 502 and the auxiliary splint 503 to loosen, making it convenient to open the mold and remove the cutter head, which not only improves the operating convenience of the mold, but also helps to extend the service life of the mold.

[0038] The working principle of this embodiment is as follows: During use, the diamond particles and metal powder mixture are first placed in the mold cavity between the first inner mold 2, the second inner mold 3 and the third inner mold 4 to adjust the position so that the diamond particles and metal powder mixture can be evenly distributed in the mold cavity. By turning the threaded knob 305, the position of the middle clamp 302 can be adjusted, and then the overall structure of the second inner mold 3 can be adjusted so 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 clamp 401, and the sliding connection design between the third slide groove 405 and the fixed slide rod 407, make the second long clamp 402 and the second flat clamp 403 more flexible and accurate when adjusting the position, thereby adapting to the die-casting requirements of different diamond bits.

[0039] After the mold adjustment is completed, the auxiliary clamping assembly 5 clamps the mold during the die casting process, specifically, the press presses the pressing block 502, so that the push plate 504 slides on the mounting column 506, and drives 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, prevent the diamond tool bit from displacement or loosening, thereby ensuring the forming precision and quality of the product.

[0040] When the die casting is completed, the pressing block 502 is loosened, the spring 505 pushes the push plate 504 to reset, thereby driving the pressing block 502 and the auxiliary clamping plate 503 to loosen, facilitating the opening of the mold and the removal of the tool bit, at this time, the positions of the threaded knob 305 and the rotating plate 404 can be adjusted to quickly disassemble and replace each part of the mold for the next round of production.

[0041] In summary, the diamond tool bit die casting mold of the present application realizes efficient, accurate and stable production of the diamond tool bit die casting mold by adopting the design of the modularized spliced inner mold and the auxiliary clamping assembly 5, improves the forming quality and production efficiency of the product, reduces the production cost, and has wide application prospect and market value.

[0042] The above is only a preferred embodiment of the present application, and is not intended to limit the protection scope of the present application.
