Description

Technical Field

[0001] This invention relates to the technical field of artificial stone machine tool manufacturing, and in particular to an automated pouring equipment and pouring process. Background Technology

[0002] Artificial stone machine tools do not mean that the entire machine tool is made of stone. Rather, it means that the basic structural components of the machine tool, such as the bed, column, crossbeam, and worktable base, are made of artificial granite or polymer concrete, rather than traditional cast iron or welded steel.

[0003] Artificial stone has 6 to 10 times the damping properties of cast iron, thus possessing excellent shock absorption and damping performance. During the cutting process, vibration can cause vibration marks on the workpiece surface, affecting the smoothness. The artificial stone bed can quickly absorb and attenuate these vibrations, thereby obtaining a smoother and higher quality machined surface. Furthermore, the production process does not require high-temperature smelting like cast iron, resulting in low energy consumption and no waste gas emissions. Aggregate sources are also widely available, with natural granite fragments being readily available.

[0004] In the existing technology, artificial stone machine tool parts are usually cast by mixing granite aggregate and binder. In order to make the molded artificial stone machine tool parts more compact, aggregates of different sizes are usually mixed to reduce the gap between the aggregates. However, during the transportation process after the aggregate and binder are mixed, materials with different densities and particle sizes separate due to flow, resulting in uneven composition of various parts of the casting. Summary of the Invention

[0005] In order to reduce the probability of aggregate separation due to the flow of materials with different densities and particle sizes, this application provides an automated casting equipment.

[0006] Firstly, this application provides an automated pouring equipment, which adopts the following technical solution: An automated casting equipment includes a workbench and a vacuum mixing mechanism. A conveyor belt is installed on the workbench, and a mold is placed on the conveyor belt. An injection mechanism and a compaction mechanism are also installed on the workbench. The injection mechanism includes a first mounting frame, which is fixedly connected to the workbench. An injection head is installed on the first mounting frame via a lifting component. The injection head is connected to the vacuum mixing mechanism via a material conveying component. The material conveying assembly includes a material distribution pipe, which is installed at the discharge end of the vacuum stirring mechanism. The two discharge ends of the material distribution pipe are respectively fixedly connected to a first spiral material conveying pipe and a second spiral material conveying pipe. A first discharge pipe is fixedly connected to the first mounting bracket. The discharge ends of the first spiral material conveying pipe and the second spiral material conveying pipe are both connected to the first discharge pipe and are located at both ends of the first discharge pipe. A second discharge pipe is slidably connected to the end of the first discharge pipe near the injection head. The second discharge pipe is fixedly connected to the injection head.

[0007] By adopting the above technical solution, when casting artificial stone machine tool parts, a corresponding mold is first made according to the shape of the part. The mold is then placed on a conveyor belt. Aggregates and binders of different particle sizes and densities are then added to a vacuum mixing mechanism for mixing. After mixing, the aggregate-binder mixture is injected into the first discharge pipe through the first and second spiral conveyor pipes, and then into the mold through the second discharge pipe and injection head. The conveyor belt then transports the mold to the compaction mechanism, which compacts the aggregate-binder mixture in the mold. When the fluid flows in the curved pipe, due to centrifugal force... In this process, the faster-flowing fluid in the center of the pipe is thrown outwards, while the slower-flowing fluid near the pipe wall is forced inwards. This motion forms a double-vortex-shaped secondary flow. These two symmetrical vortices continuously exchange the fluid between the center and the outer wall of the pipe, which completely breaks the stratification caused by laminar flow and achieves full mixing in the cross-sectional direction of the pipe. When the mixture enters the first discharge pipe, due to inertia, the mixture flowing out of the first spiral conveyor pipe and the second spiral conveyor pipe collide and generate impact, further improving the mixing of aggregate and binder, and further reducing the probability of separation of materials with different densities and particle sizes due to flow.

[0008] Optionally, a first sliding groove is provided on the inner sidewall of both ends of the first mounting frame. The lifting assembly includes a lifting plate, and the two ends of the lifting plate are slidably connected in the two first sliding grooves. Two first electric push rods are also fixedly connected to the first mounting frame. The piston shafts of the two first electric push rods are fixedly connected to the lifting plate. The two first electric push rods are controlled by the same controller. The lifting plate is fixedly connected to the injection head.

[0009] By adopting the above technical solution, since the height of the machine tool parts to be cast is different, the height of the mold is also different. Therefore, it is necessary to make the injection head adjustable in the height direction. The setting of the lifting plate and the first electric push rod realizes the lifting of the injection head, thereby realizing the injection of molds of different heights and improving the applicability of the whole device.

[0010] Optionally, the vacuum stirring mechanism includes a stirring tank with an inlet and an outlet at each end. The stirring tank is mounted on the ground via a bracket. A stirring motor is fixedly connected to the inlet end of the stirring tank. The stirring motor is driven by a reducer to a stirring shaft. Multiple stirring blades are fixedly connected to the side wall of the stirring shaft. A vacuum pump is also mounted on the bracket and is connected to the stirring tank via a connecting pipe and a filter assembly.

[0011] By adopting the above technical solution, when mixing aggregates and binders, the aggregates and binders are first injected into the mixing tank through the feed port, then the feed port is sealed, and then the vacuum pump is started to create a vacuum environment inside the mixing tank. Mixing in a vacuum environment can remove air trapped in the material, reduce the phenomenon of pores inside the casting, and thus reduce the probability that pores will become stress concentration points, affecting strength and accuracy.

[0012] Optionally, the filter assembly includes a mounting plate, which is fixedly connected to the bracket. A filter box is fixedly connected to the mounting plate. The connecting pipe communicates with the filter box. One end of the filter box is open. A filter screen is installed inside the filter box. A sealing cap is installed at the open end of the filter box.

[0013] By adopting the above technical solution, when the aggregates are added, the collision between the aggregates will generate relatively fine aggregate dust. Installing a filter screen on the vacuum pipeline reduces the probability of fine aggregate dust being sucked into the vacuum pump and causing damage.

[0014] Optionally, the compaction mechanism includes a second mounting bracket, which is fixedly connected to the workbench. A second sliding groove is provided on the inner top wall of the second mounting bracket, and a slider is slidably connected in the second sliding groove. A second electric push rod is fixedly connected to the end face of the slider near the workbench. A lower pressure block is installed on the piston shaft of the second electric push rod through a connecting assembly. A pressure plate is also installed on the mold.

[0015] By adopting the above technical solution, since there is a need to add pre-embedded cast iron parts during the manufacturing process of artificial stone machine tool parts, when the height of the pre-embedded cast iron parts exceeds the height of the mold, the compaction of aggregate and binder becomes very inconvenient. Therefore, in this application, a pressure plate that matches the shape of the machine tool parts and the position of the pre-embedded parts is customized. When the aggregate and binder are compacted, the second electric push rod drives the lower pressure block to press on the pressure plate through the connecting assembly, thereby achieving the compaction of aggregate and binder, making the aggregate particles more compact, expelling residual micro air bubbles, and thus maximizing the density and stiffness of the material.

[0016] Optionally, the connecting assembly includes a connecting plate, which is fixedly connected to the piston shaft of the second electric push rod. A plurality of connecting nuts are fixedly connected to the end face of the connecting plate away from the second electric push rod. A connecting rod is threadedly connected to the connecting nuts, which do not interfere with the position of the embedded part, according to the position of the embedded part. The end of the connecting rod away from the connecting plate is fixedly connected to the lower pressure block.

[0017] By adopting the above technical solution, the installation of the lower pressure block is realized through the setting of connecting nuts and connecting rods. At the same time, it is also convenient to install the position of the lower pressure block according to the position of the embedded part, so that the lower pressure block does not interfere with the embedded part. Furthermore, it is convenient to install multiple lower pressure blocks, so that the lower pressure block does not interfere with the embedded part during the compaction process while maximizing the compaction effect.

[0018] Optionally, slots are provided on all four side walls of the pressing block, and a first limiting groove is provided on the top wall of the slot. An auxiliary component is installed on the pressing block. The auxiliary component includes four auxiliary plates, and the four auxiliary plates are respectively inserted into the four slots through inserts. Multiple second limiting grooves are provided on the end face of the insert near the connecting plate. A limiting block is inserted into the interconnected first limiting groove and second limiting groove.

[0019] By adopting the above technical solution, the auxiliary plate increases the contact area between the lower pressure block and the pressure plate, thereby making the pressure of the lower pressure block more uniform when it presses down. Furthermore, by adjusting the distance between the auxiliary plate and the lower pressure block through the insert block and the limiting block, the probability of interference between the auxiliary plate and the embedded parts is reduced.

[0020] Optionally, a fixing mechanism is also installed on the worktable. The fixing mechanism includes two third electric push rods, which are respectively fixedly connected to both sides of the worktable. A clamping block is fixedly connected to the piston shaft of the third electric push rod.

[0021] By adopting the above technical solution, during the pouring and compaction steps, the third electric push rod drives the clamping block to clamp the mold, thereby reducing the probability that the mold will accidentally slide during the pouring process, causing the injection head to inject the mixture of aggregate and binder outside the mold; and reducing the probability that the mold will accidentally slide under pressure during the process, causing compaction errors.

[0022] Secondly, the automated pouring process provided in this application adopts the following technical solution.

[0023] An automated pouring process includes the following steps: Step 1: Make a mold according to the shape of the artificial stone machine tool parts, and evenly coat the inner surface of the mold with a layer of release agent. Then place the mold on the conveyor belt so that it is below the injection head, and fix the mold with clamping blocks. Step 2: To obtain the highest bulk density and stiffness, use aggregates of different particle sizes, mix them in precise proportions, and then add the aggregates and binder together into the mixing tank and seal the feed port of the mixing tank. Step 3: Start the vacuum pump to create a vacuum environment inside the mixing tank, and then start the mixing motor. The mixing motor drives the mixing shaft to rotate through the reducer, and the mixing shaft drives the mixing blades to rotate, thereby realizing the mixing and mixing of aggregates and binders. Step 4: After mixing is complete, open the outlet of the mixing tank so that the mixed aggregate and binder enter the first spiral conveyor pipe and the second spiral conveyor pipe through the distribution pipe, and then are injected into the mold through the injection head; Step 5: After the injection is completed, the two clamping blocks are released from fixing the mold. Then the conveyor belt moves, causing the mold containing the mixed aggregate and adhesive to move to the position of the lower pressing block. At this time, the mold is fixed by the two clamping blocks again. Then the matching production pressure plate is placed on the mold. Then the connecting rod is installed according to the position of the embedded part so that the lower pressing block does not interfere with the embedded part. Finally, the second electric push rod is activated so that the lower pressing block abuts against the pressure plate to achieve compaction.

[0024] In summary, this application includes the following beneficial technical effects: 1. When fluid flows in a curved pipe, due to centrifugal force, the faster-flowing fluid at the center of the pipe is thrown to the outside, while the slower-flowing fluid near the pipe wall is forced to flow inward. This motion forms a double-vortex-shaped secondary flow. These two symmetrical vortices continuously exchange the fluid between the center and the outer wall of the pipe, which completely breaks the stratification caused by laminar flow and achieves full mixing in the cross-sectional direction of the pipe. When the mixture enters the first discharge pipe, due to inertia, the mixture flowing out of the first spiral conveyor pipe and the second spiral conveyor pipe collide and generate impact, which further improves the mixing of aggregate and binder, and further reduces the probability of separation of materials with different densities and particle sizes due to flow. 2. When mixing aggregates and binders, first inject the aggregates and binders into the mixing tank through the feed inlet, then seal the feed inlet, and then start the vacuum pump to create a vacuum environment inside the mixing tank. Mixing in a vacuum environment can remove air trapped in the material, reduce the occurrence of pores inside the casting, and thus reduce the probability that pores will become stress concentration points, affecting strength and accuracy. 3. Since it is necessary to add embedded cast iron parts during the manufacturing process of artificial stone machine tool parts, when the height of the embedded cast iron parts exceeds the height of the mold, the compaction of aggregate and binder becomes very inconvenient. Therefore, in this application, a pressure plate is customized to match the shape of the machine tool parts and the position of the embedded parts. When the aggregate and binder are compacted, the second electric push rod drives the lower pressure block to press on the pressure plate through the connecting component, thereby achieving the compaction of aggregate and binder, making the aggregate particles more compact, expelling residual micro air bubbles, and maximizing the density and stiffness of the material. 4. The installation of the lower pressure block is achieved by setting the connecting nut and connecting rod. It also facilitates the installation of the lower pressure block according to the position of the embedded part, so that the lower pressure block does not interfere with the embedded part. It also facilitates the installation of multiple lower pressure blocks, so that the lower pressure block does not interfere with the embedded part during the compaction process, while maximizing the compaction effect.

Detailed Implementation

[0027] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0028] This application discloses an automated pouring equipment.

[0029] refer to Figure 1 The automated pouring equipment includes a workbench 1 and a vacuum mixing mechanism 3. Both the workbench 1 and the vacuum mixing mechanism 3 are installed on the ground. A conveyor belt 2 is installed on the workbench 1, and a mold 6 is placed on the conveyor belt 2. The workbench 1 is also equipped with a material injection mechanism 4 for pouring and a compaction mechanism 5 for pressing down the aggregate and adhesive in the mold 6.

[0030] When casting artificial stone machine tool parts, the aggregate and adhesive are manually added to the vacuum mixing mechanism 3. After mixing, the aggregate and adhesive mixture is injected into the mold 6 through the injection mechanism 4. After the injection is completed, the conveyor belt 2 transports the mold 6 to the position of the compaction mechanism 5. The compaction mechanism 5 compacts the aggregate and adhesive mixture in the mold 6.

[0031] refer to Figure 1 and Figure 2The vacuum stirring mechanism 3 includes a stirring tank 32, with an inlet and an outlet at both ends of the stirring tank 32. The stirring tank 32 is installed on the ground via a bracket 31. A stirring motor 33 is fixedly connected to the inlet end of the stirring tank 32. The stirring motor 33 is driven by a reducer 34 to a stirring shaft 35. Multiple stirring blades 36 are fixedly connected to the side wall of the stirring shaft 35. A vacuum pump 37 is also installed on the bracket 31. The vacuum pump 37 is connected to the stirring tank 32 via a connecting pipe 38 and a filter assembly 39. When mixing aggregates and binders, the aggregates and binders are first injected into the mixing tank 32 through the feed port. Then the feed port is sealed, and the vacuum pump 37 is started to create a vacuum environment inside the mixing tank 32. Mixing in a vacuum environment can remove air trapped in the material, reduce the occurrence of pores inside the casting, and thus reduce the probability that pores will become stress concentration points, affecting strength and accuracy.

[0032] refer to Figure 2 and Figure 3 The filter assembly 39 includes a mounting plate 391, which is fixedly connected to the bracket 31. A filter box 392 is fixedly connected to the mounting plate 391. A connecting pipe 38 communicates with the filter box 392. One end of the filter box 392 is open. A filter screen 393 is installed inside the filter box 392. A sealing cap 394 is installed at the open end of the filter box 392. When adding aggregates, the collision between aggregates will generate relatively fine aggregate dust. Installing a filter screen 393 on the vacuum pipeline reduces the probability of fine aggregate dust being sucked into the vacuum pump 37 and causing damage.

[0033] refer to Figure 4 and Figure 5 The material injection mechanism 4 includes a first mounting frame 41, which is fixedly connected to the workbench 1. A material injection head 42 is mounted on the first mounting frame 41 via a lifting assembly 44. The material injection head 42 is connected to the mixing tank 32 via a material conveying assembly 43. The material conveying assembly 43 includes a distribution pipe 431, which is installed at the discharge end of the mixing tank 32. The two discharge ends of the distribution pipe 431 are respectively fixedly connected to a first spiral conveying pipe 432 and a second spiral conveying pipe 433. A first discharge pipe 434 is fixedly connected to the first mounting frame 41. The discharge ends of the first spiral conveying pipe 432 and the second spiral conveying pipe 433 are both connected to the first discharge pipe 434 and are located at both ends of the first discharge pipe 434. A second discharge pipe 435 is slidably connected to the end of the first discharge pipe 434 near the material injection head 42. The second discharge pipe 435 is fixedly connected to the material injection head 42.

[0034] When casting artificial stone machine tool parts, a corresponding mold 6 is first made according to the shape of the part. Then, the mold 6 is placed on the conveyor belt 2. Then, aggregates and binders of different particle sizes and densities are added to the vacuum mixing mechanism 3 for mixing. After mixing, the aggregate and binder mixture is injected into the first discharge pipe 434 through the first spiral conveying pipe 432 and the second spiral conveying pipe, and then injected into the mold 6 through the second discharge pipe 435 and the injection head 42. Then, the conveyor belt 2 transports the mold 6 to the position of the compaction mechanism 5, and then the compaction mechanism 5 compacts the aggregate and binder mixture in the mold 6. When the fluid flows in the curved pipe, due to the centrifugal force... In this process, the faster-flowing fluid at the center of the pipe is thrown outwards, while the slower-flowing fluid near the pipe wall is forced inwards. This motion forms a double-vortex-shaped secondary flow. These two symmetrical vortices continuously exchange the fluid between the center of the pipe and the outer wall, which completely breaks the stratification caused by laminar flow and achieves full mixing in the cross-sectional direction of the pipe. When the mixture enters the first discharge pipe 434, due to inertia, the mixture flowing out of the first spiral conveying pipe 432 and the second spiral conveying pipe 433 collides and generates an impact, which further improves the mixing of aggregate and binder, and further reduces the probability of separation of materials with different densities and particle sizes due to flow.

[0035] First grooves 411 are provided on the inner sidewalls at both ends of the first mounting bracket 41. The lifting assembly 44 includes a lifting plate 441, with both ends of the lifting plate 441 slidably connected in the two first grooves 411. Two first electric push rods 442 are also fixedly connected to the first mounting bracket 41. The piston shafts of the two first electric push rods 442 are fixedly connected to the lifting plate 441. The two first electric push rods 442 are controlled by the same controller. The lifting plate 441 is fixedly connected to the injection head 42.

[0036] Since the heights of the machine tool parts to be cast are different, the height of the mold 6 is also different. Therefore, it is necessary to make the injection head 42 adjustable in the height direction. The setting of the lifting plate 441 and the first electric push rod 442 realizes the lifting of the injection head 42, thereby realizing the injection of molds 6 of different heights and improving the applicability of the whole device.

[0037] refer to Figure 6 The compaction mechanism 5 includes a second mounting frame 51, which is fixedly connected to the workbench 1. The second mounting frame 51 is located at the end of the first mounting frame 41 away from the mixing tank 32. A second sliding groove is provided on the inner top wall of the second mounting frame 51. A slider 52 is slidably connected in the second sliding groove. A second electric push rod 53 is fixedly connected to the end face of the slider 52 near the workbench 1. A lower pressure block 54 is installed on the piston shaft of the second electric push rod 53 through a connecting assembly 56. A pressure plate 57 is also installed on the mold 6.

[0038] Since there is a need to add pre-embedded cast iron parts during the manufacturing process of artificial stone machine tool parts, when the height of the pre-embedded cast iron parts exceeds the height of the mold 6, the compaction of aggregate and adhesive becomes very inconvenient. Therefore, in this application, a pressure plate 57 is customized to match the shape of the machine tool parts and the position of the pre-embedded parts. When the aggregate and adhesive are compacted, the second electric push rod 53 drives the lower pressure block 54 to press on the pressure plate 57 through the connecting component 56, thereby achieving the compaction of aggregate and adhesive, making the aggregate particles more compact, expelling residual micro air bubbles, and thus maximizing the density and stiffness of the material.

[0039] The connecting assembly 56 includes a connecting plate 561, which is fixedly connected to the piston shaft of the second electric push rod 53. Multiple connecting nuts 562 are fixedly connected to the end face of the connecting plate 561 away from the second electric push rod 53. A connecting rod 563 is threadedly connected to the connecting nuts 562 that do not interfere with the position of the embedded part. The end of the connecting rod 563 away from the connecting plate 561 is fixedly connected to the lower pressure block 54.

[0040] The installation of the lower pressure block 54 is achieved by connecting the nut 562 and the connecting rod 563. This also facilitates the installation of the lower pressure block 54 according to the position of the embedded part, ensuring that the lower pressure block 54 does not interfere with the embedded part. Furthermore, it is convenient to install multiple lower pressure blocks 54, so that the lower pressure block 54 does not interfere with the embedded part during the compaction process, while maximizing the compaction effect.

[0041] refer to Figure 7 The pressing block 54 has slots 541 on its four side walls and a first limiting groove 542 on the top wall of the slots 541. An auxiliary component 55 is installed on the pressing block 54. The auxiliary component 55 includes four auxiliary plates 551. The four auxiliary plates 551 are inserted into the four slots 541 respectively through inserts 552. The inserts 552 have multiple second limiting grooves 554 on their end faces near the connecting plate 561. A limiting block 553 is inserted into the interconnected first limiting grooves 542 and second limiting grooves 554.

[0042] The auxiliary plate 551 increases the contact area between the lower pressure block 54 and the pressure plate 57, thereby making the pressure of the lower pressure block 54 more uniform when it presses down. Furthermore, the distance between the auxiliary plate 551 and the lower pressure block 54 is adjusted by the insert block 552 and the limit block 553, thereby reducing the probability of interference between the auxiliary plate 551 and the embedded part.

[0043] refer to Figure 8The workbench 1 is also equipped with a fixing mechanism 7, which includes two third electric push rods 71. The two third electric push rods 71 ​​are fixedly connected to both sides of the workbench 1, and clamping blocks 72 are fixedly connected to the piston shaft of each third electric push rod 71.

[0044] During the pouring and compaction steps, the third electric push rod 71 drives the clamping block 72 to clamp the mold 6, thereby reducing the probability that the mold 6 will accidentally slide during the pouring process, causing the injection head 42 to inject the mixture of aggregate and binder outside the mold 6; and reducing the probability that the mold 6 will accidentally slide under pressure during the compaction process, causing compaction errors.

[0045] This application also discloses an automated pouring process.

[0046] An automated pouring process includes the following steps: Step 1: Make a mold 6 according to the shape of the artificial stone machine tool parts, and evenly coat the inner surface of the mold 6 with a layer of release agent. Then place the mold 6 on the conveyor belt 2 so that it is below the injection head 42. Start the two third electric push rods 71. The two third electric push rods 71 ​​drive the two clamping blocks 72 respectively to fix the mold 6. Step 2: In order to obtain the highest bulk density and stiffness, aggregates of different particle sizes are mixed in a precise ratio, and then the aggregates and binders are added together into the mixing tank 32 and the feed port of the mixing tank 32 is sealed. Step 3: Start the vacuum pump 37 to create a vacuum environment inside the mixing tank 32, and then start the mixing motor 33. The mixing motor 33 drives the mixing shaft 35 to rotate through the reducer 34. The mixing shaft 35 drives the mixing blades 36 to rotate, thereby realizing the mixing and mixing of aggregates and binders. Step 4: After mixing is complete, open the outlet of mixing tank 32 so that the mixed aggregate and binder enter the first spiral conveying pipe 432 and the second spiral conveying pipe 433 through the distribution pipe 431, and then are injected into mold 6 through injection head 42. Step 5: After the material injection is completed, activate the two third electric push rods 71. The two third electric push rods 71 ​​will drive the two clamping blocks 72 to release the mold 6 from the fixation. Then the conveyor belt 2 will move, so that the mold 6 containing the mixed aggregate and adhesive will move to the position of the lower pressing block 54. At this time, activate the two third electric push rods 71 ​​again. The two third electric push rods 71 ​​will drive the two clamping blocks 72 to fix the mold 6. Then the matching pressure plate 57 will be placed on the mold 6. Then the connecting rod 563 will be installed according to the position of the embedded part, so that the lower pressing block 54 will not interfere with the embedded part. Finally, activate the second electric push rod 53 so that the lower pressing block 54 abuts against the pressure plate 57 to achieve compaction.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
