[0002] Currently, in the hot pressing production process of resin diamond products such as grinding wheels, some residue inevitably accumulates on the mold core. The conventional cleaning method is to clean the mold core one by one. However, since the mold core is usually quite small, it is extremely inconvenient for workers to handle and clean it.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] In the description of this utility model, it should be understood that features specified as "first" or "second" may explicitly or implicitly include one or more of those features. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" 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 utility model based on the specific circumstances.

[0027] Currently, in the hot pressing production process of resin-bonded diamond products such as grinding wheels, some residues inevitably accumulate on the mold core. Specifically, in the invention patent document with authorization announcement number CN101386154B, the resin-bonded diamond grinding wheel includes a matrix and an abrasive layer disposed on the matrix. The matrix is ​​a ring-shaped aluminum matrix, and the abrasive layer is a ring-shaped resin-bonded diamond layer.

[0028] In the manufacturing process of resin-bonded diamond grinding wheels, a circular base plate is placed inside an annular mold sleeve, and an annular substrate is placed on the base plate, with the outer wall of the substrate fitting against the inner wall of the mold sleeve. Then, a die core is inserted into the central hole of the substrate and pressed onto it. The die core is then fixed to the base plate using bolts. At this point, the inner wall of the mold sleeve, the substrate, and the outer wall of the die core together form an upward-opening chamber, allowing the abrasive mixture to be poured into the chamber. A hot-pressing process is then used to form the abrasive mixture, causing it to form an abrasive layer fixed to the substrate, thus producing a resin-bonded diamond grinding wheel.

[0029] Because the outer wall of the mold core is in contact with the agitated material, some agitated material inevitably remains on the outer surface of the mold core during the hot pressing process. To prevent this residue from affecting the manufacturing quality of the next resin diamond product, it needs to be removed. The conventional cleaning method involves manually cleaning multiple mold cores one by one. However, because the mold cores are usually small, handling and cleaning them is extremely inconvenient for workers, resulting in low efficiency and high manpower consumption in the process.

[0030] Since the aforementioned inefficient cleaning methods have become a major bottleneck restricting the improvement of production efficiency and the realization of automated production, there is an urgent need for a mold core cleaning device that can efficiently clean the residues from multiple mold cores, save manpower, and improve the production efficiency of resin diamond products.

[0031] The following is for reference. Figures 1 to 3 This invention describes a mold core cleaning device provided according to an embodiment of the present invention.

[0032] like Figures 1 to 3 As shown, the mold core cleaning device according to this embodiment of the present invention can simultaneously complete the cleaning of multiple mold cores 100, with high cleaning efficiency and saving manpower. This mold core cleaning device can be applied to the cleaning of hot-press molds for resin diamond products such as grinding wheels, especially for cleaning residues on the mold cores of hot-press molds.

[0033] The mold core cleaning device has a first direction, a second direction, and a vertical direction, wherein the first direction, the second direction, and the vertical direction are arranged perpendicularly to each other. In this embodiment, it is assumed that the first direction is the front-back direction and the second direction is the left-right direction.

[0034] like Figure 1 and Figure 2 As shown, the mold core cleaning device includes a support mechanism 200, a scraping mechanism 400, and a rotary drive mechanism. The support mechanism 200 is configured to provide support for multiple mold cores 100, the rotary drive mechanism is configured to drive all mold cores 100 located on the support mechanism 200 to rotate circumferentially, and the scraping mechanism 400 is configured to scrape all rotating mold cores 100 to clean residue from their outer circumferential surfaces.

[0035] The support mechanism 200 is provided with a support station that extends along a first direction. The support station is used to place multiple mold cores 100 sequentially along the first direction. It is understood that the central axes of the multiple mold cores 100 located on the support station extend along the first direction, the outer diameters of all mold cores 100 are the same, and the central axes of all mold cores 100 coincide.

[0036] In this embodiment, the support mechanism 200 includes a support base 210 and a support roller 220. The support roller 220 extends along a first direction, therefore, the central axis of the support roller 220 also extends along the first direction, and the support roller 220 is rotatably connected to the support base 210. It is understood that both ends of the support roller 220 may be provided with rotating shaft portions, which are fixedly connected to the support roller 220. The rotating shaft portions are correspondingly inserted into the shaft holes provided in the support base 210, allowing the support roller 220 to rotate relative to the support base 210 around its own central axis.

[0037] Alternatively, the support roller 220 can have shaft holes at both ends, and the support base 210 can have a rotating shaft. The rotating shaft is adapted to the shaft holes, allowing the support roller 220 to rotate relative to the support base 210. The support roller 220 can be a solid or hollow structure. The shape and size of the support base 210 can be set according to actual needs and are not specifically limited here.

[0038] Two support rollers 220 are provided, and the two support rollers 220 are arranged at a certain interval along a second direction to form a support station. At this time, multiple mold cores 100 are placed between the two support rollers 220, and the outer circumferential surfaces of the two support rollers 220 can contact the outer circumferential surfaces of all mold cores 100, so that all mold cores 100 can receive the support provided by the two support rollers 220. It can be understood that since the support rollers 220 can rotate relative to the support base 210, the support rollers 220 can rotate during the rotation of the mold cores 100 driven by the rotary drive mechanism, which can reduce the friction between the support rollers 220 and the mold cores 100, thereby helping to reduce the energy consumption of the rotary drive mechanism.

[0039] Of course, it is not excluded that in other embodiments, the support roller 220 and the support base 210 are fixedly connected. In addition, the support mechanism 200 may only include the support base 210, which is provided with a V-shaped or inverted trapezoidal receiving groove. The opening of the receiving groove is open upward and extends along a first direction. When the mold core 100 is placed in the receiving groove, the two opposite inclined walls of the receiving groove can support the mold core 100.

[0040] Furthermore, the support mechanism 200 can be fixed to the worktable by bolt installation, ensuring good stability of the mold core cleaning device during operation. The support mechanism 200 can be, but is not limited to, made of high-strength aluminum alloy.

[0041] The scraping mechanism 400 includes a scraper 410, which is located on one side of the support station along a second direction. The scraper 410 has a cutting edge 411 extending along a first direction and capable of contacting the outer circumferential surface of the mold core 100. It is understood that in some examples, the scraper 410 may be horizontally positioned, with the cutting edge 411 located between the highest and lowest points of the mold core 100. In other examples, the scraper 410 may be inclined. The scraper 410 may be fixedly connected to the support mechanism 200.

[0042] In this embodiment, the scraping mechanism 400 further includes a mounting base and a spring 430. The scraper 410 is slidably connected to the mounting base along a second direction, and the spring 430 is extendable and retractable along the second direction, with its two ends fixedly connected to the scraper 410 and the mounting base, respectively. Therefore, under the elastic force of the spring 430, the scraper 410 can move stably relative to the mounting base along the second direction and approach the outer circumferential surface of the mold core 100, ensuring that the cutting edge 411 of the scraper 410 is always in contact with the outer circumferential surface of the mold core 100, thereby removing all residue from the outer circumferential surface of the mold core 100.

[0043] It is understood that the number of springs 430 is not limited to one. The scraper 410 and the mounting base can be slidably connected via a guide rail slider pair, a guide shaft sleeve combination, or a concave-convex structure. In this embodiment, there are two springs 430, spaced apart along the first direction. Furthermore, the two springs 430 are symmetrically arranged about the center position of the scraper 410 along the first direction, thus ensuring more even force distribution on the scraper 410. When the cutting edge 411 of the scraper 410 contacts the outer circumferential surface of the mold core 100, the spring 430 is in a compressed state. The scraper 410 can be made of powder metallurgy material.

[0044] Furthermore, the scraper 410 is provided with a limiting hole 412, which extends through the vertical direction and also extends in a second direction. The mounting base is provided with a limiting post 424, which can be integrally formed with the mounting base. The limiting post 424 extends in the vertical direction and is arranged in a one-to-one correspondence with the limiting hole 412. The limiting post 424 extends into the limiting hole 412.

[0045] It is understood that the limiting post 424 can be cylindrical or quadrangular prism-shaped. The number of limiting posts 424 is not limited to one. By setting the limiting post 424 and the limiting hole 412, the movement distance of the scraper 410 in the second direction can be limited. The limiting post 424 is fitted to the inner wall surface of the limiting hole 412, which can improve the movement stability of the scraper 410.

[0046] Of course, it is not excluded that in other embodiments, the scraper 410 is provided with a limiting post 424 and the mounting base is provided with a limiting hole 412, with the limiting post 424 inserted into the limiting hole 412.

[0047] In one specific embodiment, the mounting base includes a mounting plate 421, a fixing plate 423, and a pressure plate 422. The mounting plate 421 is bolted to the support mechanism 200. The mounting plate 421 has two spaced-apart limiting posts 424 along a first direction, and correspondingly, the scraper 410 has two limiting holes 412. The pressure plate 422 is positioned above the mounting plate 421 and bolted to it. There are two pressure plates 422, each with a sliding groove extending along a second direction defined between it and the mounting plate 421. The scraper 410 is inserted into the sliding groove at both ends along the first direction. The fixing plate 423 extends along the first direction and is located on the side of the pressure plate 422 away from the support station along the second direction. It is fixedly connected to the two pressure plates 422 by bolts. The fixing plate 423 and the scraper 410 are both provided with two positioning grooves. There are two springs 430, which are respectively set with the two positioning grooves. The two ends of the springs 430 abut against the bottom surface of the two positioning grooves respectively.

[0048] The rotary drive mechanism includes a rotary shaft 310, a clamping member 350, and a rotary drive member. The rotary shaft 310 extends along a first direction, and therefore its central axis also extends along the first direction. A limiting portion is provided on the outer circumferential surface of the rotary shaft 310, and the limiting portion can be integrally formed with the rotary shaft 310. The rotary shaft 310 is located between two support rollers 220 and positioned above the support rollers 220. The rotary shaft 310 is cylindrical, and the limiting portion can be annular or a plurality of circumferentially arranged protrusions surrounding the rotary shaft 310; the protrusions can be fan-shaped.

[0049] The rotary drive is configured to drive the rotary shaft 310 to rotate about its own central axis. The rotary drive and the clamping member 350 are located on opposite sides of the rotary shaft 310 along a first direction. One end of the rotary shaft 310 is connected to the output end of the rotary drive, and the other end of the rotary shaft 310 is detachably connected to the clamping member 350, so that the clamping member 350 and the limiting part together clamp all the mold cores 100 sleeved on the rotary shaft 310.

[0050] Understandably, the rotary drive component can be a motor 320, which can be connected to the rotary shaft 310 via a coupling, gear transmission structure, or crank-connecting rod structure. Alternatively, the rotary drive component can be a rotary cylinder 330. The rotary drive component can be fixedly connected to the support mechanism 200. The rotary drive component can drive the rotary shaft 310 to rotate clockwise or counterclockwise.

[0051] The clamping member 350 can be cylindrical and detachably connected to the rotating shaft 310 via a threaded structure or a rotating snap-fit ​​structure. Since the mold core 100 has a central hole, it can be fitted onto the rotating shaft 310. After multiple mold cores 100 are fitted onto the rotating shaft 310, the clamping member 350 is installed on the rotating shaft 310, allowing the clamping member 350 and the limiting part to clamp all the mold cores 100 located on the rotating shaft 310, ensuring that all mold cores 100 are fixed relative to the rotating shaft 310. Then, by operating the rotating drive, the rotating shaft 310 is driven to rotate, causing the clamping member 350, the limiting part, and all the mold cores 100 to rotate together with the rotating shaft 310, allowing the scraper 410 to scrape away residue from the outer circumferential surface of all the mold cores 100.

[0052] Of course, in other embodiments, the rotary drive mechanism may include a push plate and a drive component. The push plate may be inclined, and its lower surface may contact the outer circumferential surface of all mold cores 100 located on the rotating shaft 310. Through linear movement of the push plate, it can drive all mold cores 100 to rotate. The push plate may include a plate body and a pad. The plate body may be made of wood, plastic, or metal such as iron, and the pad may be a rubber layer fixed to the plate body. The lower surface of the pad abuts against the outer circumferential surface of the mold core 100. The drive component can drive the push plate to move, causing it to apply a pushing force to the mold cores 100, allowing all mold cores 100 to rotate around their own central axis, thereby causing the scraper 410 to scrape off residue from the mold cores 100. Alternatively, the push plate may be driven manually.

[0053] In the use of the mold core cleaning device provided in this embodiment, multiple mold cores 100 are placed sequentially on the support station of the support mechanism 200 along the first direction, and the rotation drive mechanism is used to make all mold cores 100 rotate around their own central axis. At this time, since the blade part 411 of the scraper 410 is in contact with the outer circumferential surface of all mold cores 100, the blade part 411 of the scraper 410 can scrape off the residue on the outer circumferential surface of the mold core 100 during the rotation of the mold core 100, thereby realizing the simultaneous completion of the cleaning work of multiple mold cores 100, improving cleaning efficiency, saving manpower input, and helping to improve the manufacturing efficiency of resin diamond products.

[0054] In some embodiments, such as Figure 1 and Figure 2 As shown, the mounting base and the support mechanism 200 are fixedly connected by a first bolt. Specifically, the mounting base has an elongated hole for the first bolt to extend into, and the support mechanism 200 has a connecting hole for the first bolt to extend into. Therefore, before the first bolt passes through the elongated hole and the connecting hole to fix the support mechanism 200 to the mounting base, the position of the first bolt in the second direction within the elongated hole can be adjusted, thereby adjusting the position of the blade 411 of the scraper 410 relative to the support position. This ensures that the blade 411 of the scraper 410 can abut against the outer circumferential surface of the mold core 100, and prevents the spring 430 from being excessively compressed when the scraper 410 contacts the mold core 100.

[0055] Understandably, the connecting hole can be a threaded hole, a slotted hole, or a smooth round hole. When the connecting hole is a threaded hole, the first bolt may not have a nut. When the connecting hole is a slotted hole or a smooth round hole, the first bolt is threaded with a nut.

[0056] Of course, it is not excluded that in other embodiments, the support mechanism 200 is provided with an elongated hole for the first bolt to be inserted, and the mounting base is provided with a connecting hole for the first bolt to be inserted.

[0057] In some embodiments, such as Figure 1 and Figure 2 As shown, the rotary drive mechanism also includes a linear drive member. The output end of the linear drive member is fixedly connected to the end of the clamping member 350 away from the rotating shaft 310. The linear drive member is configured to drive the clamping member 350 to move linearly along a first direction, approaching or moving away from the rotating shaft 310. Furthermore, the end of the clamping member 350 near the rotating shaft 310 has a groove, the opening of which faces the rotating shaft 310 and is positioned opposite to the end of the rotating shaft 310 along the first direction, allowing the end of the rotating shaft 310 to extend into or exit the groove. The rotating shaft 310 is configured to move in and out of the groove of the clamping member 350.

[0058] In this embodiment, the linear drive is a cylinder 330, and the movable rod 331 of the cylinder 330 is connected to the clamping member 350. Of course, in other embodiments, the linear drive may be an electric cylinder, a hydraulic cylinder, or a linear module, etc.

[0059] It is understood that the clamping member 350 can be cylindrical, the groove can be cylindrical, and it can be adapted to the end of the rotating shaft 310. Driven by the linear drive, the clamping member 350 moves along the first direction and fits onto the rotating shaft 310, allowing it to engage with the limiting part to clamp and fix all the mold cores 100 on the rotating shaft 310. One end of the rotating shaft 310 can be mounted on the support mechanism 200 via a bearing, while the other end is suspended. After the rotating shaft 310 extends into the groove of the clamping member 350, the clamping member 350 provides some support to the other end of the rotating shaft 310.

[0060] The surface of the clamping member 350 that contacts the mold core 100 is a smooth, flat surface. The surface of the limiting part that contacts the mold core 100 is a rough surface with a high coefficient of friction. After the clamping member 350 and the limiting part clamp all the mold cores 100, the rotating shaft 310 rotates under the driving action of the rotating drive member. At this time, due to the certain friction between the limiting part and the mold core 100, the mold core 100 can rotate together with the rotating shaft 310, while the clamping member 350 remains fixed.

[0061] After the cleaning work is completed, the linear drive can drive the clamping member 350 away from the rotating shaft 310 in the first direction, so that the rotating shaft 310 is dislodged from the groove of the clamping member 350, and the mold core 100 can be dislodged from one end of the rotating shaft 310, thereby completing the mold core 100 unloading work.

[0062] Of course, it is not excluded that in other embodiments, the rotating shaft 310 includes a first shaft and a second shaft. The first shaft is fixedly connected to the output end of the rotating drive component, and the second shaft can be fixed to the first shaft by bolt connection. The first shaft and the second shaft are coaxially arranged. Then, when loading is required, all mold cores 100 are pre-fitted onto the second shaft and the second shaft is fixed to the first shaft. When unloading is required, the second shaft is directly removed from the first shaft. In this way, it is not necessary to place each mold core 100 onto the rotating shaft 310, which can improve loading and unloading efficiency.

[0063] Furthermore, the clamping member 350 is rotatably connected to the output end of the linear drive member, and the rotation axis of the clamping member 350 coincides with the rotation axis of the rotating shaft member 310.

[0064] In this embodiment, the linear drive component is a cylinder 330, and the clamping component 350 can be mounted on the movable rod 331 of the cylinder 330 via a bearing. The clamping component 350 can move linearly under the driving action of the cylinder 330. Moreover, after the clamping component 350 and the limiting part firmly clamp all the mold cores 100 located on the rotating shaft 310, the motor 320 is started to make the rotating shaft 310 rotate. At this time, the clamping component 350 and all the mold cores 100 can rotate together with the rotating shaft 310, which makes it easier for the scraper 410 to scrape off the residue on the outer circumferential surface of the mold cores 100.

[0065] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the two ends of the support roller 220 are connected to the support base 210 by the second bolts. Specifically, the support base 210 has end plates 211 on both sides along the first direction. The end plates 211 are fixed to the support base 210 by bolts, and the distance between the two end plates 211 along the first direction is equal to the length of the support roller 220.

[0066] The motor 320 is mounted on one end plate 211, and the rotating shaft 310 is mounted on the end plate 211 via bearings. The other end plate 211 is provided with a sleeve 340, on which the cylinder 330 is fixed. The movable rod 331 of the cylinder 330 passes through the sleeve 340 and is fixedly connected to the clamping member 350. The end plate 211 is provided with a through hole to allow the clamping member 350 to enter and exit, moving closer to or further away from the rotating shaft 310 in a first direction. The sleeve 340 can guide the movable rod 331 of the cylinder 330; specifically, a portion of the inner circumferential surface of the sleeve 340 is fitted against the outer circumferential surface of the movable rod 331 of the cylinder 330.

[0067] Furthermore, each end plate 211 is provided with two hole arrays, which are arranged at certain intervals along the second direction. The two hole arrays are located below the rotating shaft 310, and are symmetrically arranged about the rotation axis of the rotating shaft 310. Each hole array includes multiple mounting holes for inserting a second bolt, and the mounting holes are arranged at certain intervals along any radial direction of the rotating shaft 310.

[0068] Understandably, the number of mounting holes is two or more. The mounting holes can be threaded holes or smooth round holes. In some examples, the mounting hole is a threaded hole, and a second bolt is screwed into the mounting hole and extends into the positioning groove provided in the support roller 220. In this case, the support roller 220 can rotate relative to the support base 210. In other examples, the mounting hole is a smooth round hole, and a second bolt passes through the mounting hole and is screwed into the threaded hole provided in the support roller 220. In this case, the support roller 220 can also rotate relative to the support base 210.

[0069] Of course, when the support roller 220 is fixed relative to the support base 210, the support roller 220 is provided with a screw hole, and the mounting hole on the end plate 211 can be a screw hole. The second bolt passes through the mounting hole on the end plate 211 and the screw hole of the support roller 220 to fix the support roller 220 on the support base 210.

[0070] It is understandable that by adopting the above-mentioned setting method, the position of the support roller 220 can be adjusted so that the support roller 220 can provide support for mold cores 100 of different diameters, ensuring that the central axis of the mold core 100 and the central axis of the rotating shaft 310 both extend in the first direction, and preventing the rotating shaft 310 from shaking greatly during rotation, thereby improving working stability.

[0071] like Figure 3 As shown, the arrangement direction of the multiple mounting holes forms a certain angle θ with the vertical direction, and the value of the angle θ can be set according to actual needs. In this embodiment, the angle θ is 45°. The larger the outer diameter of the mold core 100, the lower the support roller 220 is positioned, and the farther away it is from the rotating shaft 310 along the second direction.

[0072] The mold core cleaning device provided in this embodiment of the utility model has the advantages of high-efficiency cleaning, saving manpower, and good cleaning effect. Specifically, the mold core cleaning device can simultaneously accommodate and clean multiple (e.g., 12 or more) mold cores 100, which greatly improves the cleaning efficiency compared with the conventional single cleaning method, and can complete the cleaning work of a large number of mold cores 100 in a short time.

[0073] By enabling simultaneous cleaning of multiple mold cores 100, reliance on manual operation can be reduced, thus lowering labor costs. Operators only need to load the mold cores 100 onto the rotating shaft 310, significantly saving manpower. Moreover, the mold core cleaning device can thoroughly and efficiently clean residues on the outer circumferential surface of the mold cores 100, ensuring that the mold cores 100 are thoroughly cleaned and meet production requirements.

[0074] Furthermore, mold core cleaning devices lay the foundation for automated production. These devices are easily integrated with automated production equipment, enabling automated operation of the entire cleaning process. This provides strong support for intelligent and automated production, further improving production efficiency and product quality.
