Description

Technical Field

[0001] This application belongs to the field of casting processing technology, specifically relating to a casting post-processing equipment and a casting post-processing method. Background Technology

[0002] During the casting process, castings usually have casting residues such as molding sand and sand cores attached to their surface and inner cavity after forming. They also have excess metal structures such as gating and risers. They need to go through a series of post-processing steps such as vibration sand removal, cleaning, and cutting risers before they can enter the subsequent machining stage.

[0003] Traditional post-processing of castings often employs a decentralized approach, with vibration desanding, cleaning, and riser cutting performed on different equipment. This requires multiple hoisting and transfers of the workpiece, consuming significant production space, resulting in long waiting times between processes, discontinuous production cycles, low overall automation, and severely impacting production efficiency. Furthermore, the independent operation of each process makes centralized protection difficult, and dust, noise, and metal debris generated during vibration and cutting are easily dispersed, creating a harsh working environment and posing safety hazards. Summary of the Invention

[0004] To address at least one of the technical problems existing in the background art, this application provides a casting post-processing equipment.

[0043] 1. The casting post-processing equipment provided in the first aspect of this application, by setting a worktable to carry the casting body and transport it to the vibration desanding zone, casting cleaning zone, and riser cutting zone distributed sequentially along the Y-axis, realizes continuous automatic operation of multiple processes. In particular, after the casting body is positioned and clamped at the initial position of the worktable, the clamping system moves synchronously with the worktable, passing through the three functional areas of the vibration desanding zone, casting cleaning zone, and riser cutting zone. In the entire post-processing process, there is no relative disassembly or repositioning between the casting and the clamping system, ensuring the high consistency of the positioning reference between each process. Here, the Y-axis refers to the width direction of the equipment. The vibration desanding mechanism applies vibration force to the casting in the vibration desanding zone, using mechanical vibration to achieve dry desanding, effectively removing sand from the surface of the casting and Most of the residual molding sand in the mold cavity is removed, avoiding the water pollution and waste sand disposal problems caused by traditional wet sand cleaning. At the same time, the waste sand is kept dry, which facilitates subsequent recycling and reuse. The casting cleaning mechanism uses high-pressure liquid jet cleaning on the castings after vibration treatment in the casting cleaning area, focusing on removing residual sand particles in complex internal cavities or dead corners, ensuring that the cleanliness of the castings meets the requirements of subsequent processing, and improving the targeting and efficiency of cleaning. The riser cutting mechanism saws and separates the excess metal parts such as gating and risers on the castings in the riser cutting area, achieving precise removal of non-functional structures. The waste sand recycling mechanism automatically collects the waste sand that falls off during the vibration sand removal process and centrally transports it to prevent on-site dust and environmental pollution. The riser recycling mechanism collects and transports the metal chips and riser material generated by cutting, which facilitates resource recycling. By integrating vibration sand removal, liquid cleaning, riser cutting, and the classification and recycling of two types of waste into the same equipment, the entire post-processing operation can be completed at a single station. This significantly reduces the number of workpiece transfers and hoisting time, improves production continuity and operational efficiency, reduces manual labor intensity, and features a compact layout that saves space. It can also effectively control noise and dust spillage, thus improving the working environment. Attached Figure Description

[0059] like Figures 1 to 6 As shown, a first aspect of this application provides a casting post-processing apparatus, comprising:

[0060] The workbench 11 is suitable for carrying the casting body and transporting the casting body to the preset work area. Along the Y-axis, the preset work area includes a vibration desanding area, a casting cleaning area and a riser cutting area.

[0061] The vibration desanding mechanism 12 is located at one end of the movement path of the worktable 11 along the Y-axis and distributed in the vibration desanding area. The vibration desanding mechanism 12 is located above the worktable 11. The vibration desanding mechanism 12 is suitable for applying vibration force to the casting body to achieve dry desanding of the casting body.

[0062] The casting cleaning mechanism 13 is located in the middle area of ​​the worktable 11 along the Y-axis movement path and distributed in the casting cleaning area. The casting cleaning mechanism 13 is located below the worktable 11. The casting cleaning mechanism 13 is suitable for liquid spray cleaning of the casting body to remove residual sand on the surface of the casting body.

[0063] The riser cutting mechanism 14 is located at the other end of the Y-axis moving path of the worktable 11 and distributed in the riser cutting area. The riser cutting mechanism 14 is suitable for sawing the redundant parts of the casting body.

[0064] Specifically, the workbench 11 is the core load-bearing and conveying component in the casting post-processing equipment. It is used to stably place the casting body and automatically transport it to preset stations such as the vibration desanding area, casting cleaning area, and riser cutting area through a sliding method of gear and rack transmission, ball screw, linear motor drive, hydraulic cylinder drive, or guide rail slider combined with chain / cable traction. The workbench 11 is slidably mounted on the equipment frame.

[0065] Furthermore, the workbench 11 can complete the one-time positioning and clamping operation of the casting body at the initial loading station of the equipment. Once clamped, the casting body is always fixed by the same clamping system throughout the entire post-processing process—including vibration desanding, high-pressure cleaning, and riser cutting—without the need for disassembly or repeated clamping. This "one-time clamping, full-process processing" mode not only significantly improves loading and unloading efficiency and reduces manual intervention, but more importantly, it ensures the consistency of benchmarks between each process.

[0066] The vibration desanding mechanism 12 is located in the vibration desanding zone. It is mainly used to apply high-frequency vibration force to the casting, so that most of the molding sand on its surface and in the cavity can fall off without the use of water, thus achieving dry desanding.

[0067] The casting cleaning mechanism 13 is located in the casting cleaning area and is used to perform liquid spray cleaning on the castings after vibration desanding, focusing on removing the small amount of residual sand remaining in the inner cavity and dead corners. The cleaning process is controlled by PLC, and the cleaning path and time can be set according to different castings to ensure thorough cleaning, effectively improve the surface cleanliness of the castings, and provide a good foundation for subsequent machining.

[0068] The riser cutting mechanism 14 is located in the riser cutting area and is used to saw off and separate excess metal parts such as gatings and risers on castings. The cutting process is automatically controlled, with precise positioning and a smooth cut. It replaces traditional manual gas cutting, significantly improving operational safety and consistency, and is suitable for riser removal of castings of various materials and sizes.

[0069] According to the casting post-processing equipment provided in this application embodiment, by setting a worktable 11 to carry the casting body and transport it to the vibration desanding zone, casting cleaning zone and riser cutting zone distributed sequentially along the Y-axis, continuous automatic operation of multiple processes is realized. In particular, after the casting body is positioned and clamped at the initial position of the worktable 11, the clamping system moves synchronously with the worktable 11, passing through the three functional areas of vibration desanding zone, casting cleaning zone and riser cutting zone. In the entire post-processing process, there is no relative disassembly and repositioning between the casting and the clamping system, ensuring the high consistency of the positioning reference between each process; the vibration desanding mechanism 12 applies vibration force to the casting in the vibration desanding zone, and realizes dry desanding by using mechanical vibration, effectively removing most of the residual molding sand on the surface of the casting and in the cavity. This system avoids the water pollution and waste sand disposal problems associated with traditional wet sand cleaning, while keeping the waste sand dry for easy recycling. The casting cleaning mechanism 13 uses high-pressure liquid jet cleaning on the castings after vibration treatment in the casting cleaning area, focusing on removing residual sand particles in complex internal cavities or dead corners, ensuring that the cleanliness of the castings meets the requirements of subsequent processing, and improving the targeting and efficiency of cleaning. The riser cutting mechanism 14 saws and separates excess metal parts such as gatings and risers on the castings in the riser cutting area, achieving precise removal of non-functional structures. The waste sand recycling mechanism 15 automatically collects the waste sand that falls off during the vibration sand removal process and transports it centrally to prevent dust and environmental pollution on site. The riser recycling mechanism 16 collects and transports the metal chips and riser materials generated by cutting, facilitating resource recycling. By integrating vibration sand removal, liquid cleaning, riser cutting, and the classification and recycling of two types of waste into the same equipment, the entire post-processing operation can be completed at a single station. This significantly reduces the number of workpiece transfers and hoisting time, improves production continuity and operational efficiency, reduces manual labor intensity, and features a compact layout that saves space. It can also effectively control noise and dust spillage, thus improving the working environment.

[0070] like Figure 1 As shown, in some embodiments of this application, the worktable 11 is disposed on the equipment frame and translates relative to the equipment frame, wherein the translation direction of the worktable 11 is parallel to the Y-axis;

[0071] The worktable 11 is equipped with a workpiece clamping table 111;

[0072] The worktable 11 is also equipped with a telescopic cylinder 112. The end of the telescopic cylinder 112 abuts against the workpiece clamping table 111 to adjust the clamping distance of the workpiece clamping table 111.

[0073] The workpiece clamping table 111 on the worktable 11 is used to support and fix the casting body. The workpiece clamping table 111 is equipped with a casting clamping device 1110, which can apply pressure from above after the casting is placed in place to ensure its stability during vibration, cleaning and cutting, and prevent the casting from loosening, shifting or even falling off due to severe vibration or high-speed cutting, thereby ensuring processing accuracy and operation safety.

[0074] Furthermore, the worktable 11 is also equipped with a telescopic cylinder 112, the end of which abuts against the workpiece clamping table 111. The telescopic movement of the cylinder pushes the workpiece clamping table 111 to move along the X-axis. The X-axis refers to the length direction of the equipment. This dynamically adjusts the clamping distance of the workpiece clamping table 111 to meet the clamping requirements of castings of different widths or sizes.

[0075] It is worth noting that the adjustable clamping spacing not only enhances the equipment's compatibility with various casting types, but also plays a crucial synergistic role in the process execution: when the two clamping parts of the workpiece clamping table 111 are driven by the telescopic cylinder 112 to retract towards the center and clamp the casting, an annular or lateral open channel is naturally formed between its outer side and the worktable 11 or equipment base. These channels serve as sand drop outlets during the vibration desanding process, allowing molding sand that falls off from the bottom or side of the casting to smoothly pass through the clamping table gap and fall directly into the waste sand recovery mechanism 15 below, preventing sand particles from accumulating in the clamping area and affecting equipment operation or damaging components.

[0076] The worktable 11 integrates automatic Y-axis conveying, X-axis clamping distance adjustment, and clamping and fixing functions, enabling multi-station continuous processing of castings. The clamping distance is adjusted via the telescopic cylinder 112, giving the equipment excellent versatility and adaptability, compatible with the production of castings of various specifications without the need to change fixtures, thus reducing changeover time. The casting clamping device 1110 effectively improves the stability of the processing, especially preventing workpiece displacement under high-frequency vibration and high-speed cutting conditions, thereby enhancing operational safety and product quality consistency.

[0077] like Figure 1 As shown, in some embodiments of this application, a Y-axis moving rack 113 is provided on the equipment frame, a gear matching the Y-axis moving rack 113 is provided on the worktable 11, and a Y-axis motion motor 114 for driving the gear to rotate is also provided on the worktable 11.

[0078] The workpiece clamping table 111 includes a first clamping part 1111, a second clamping part 1112, and a sliding guide rod 1113. The first clamping part 1111 and the second clamping part 1112 are slidably connected to the sliding guide rod 1113, wherein the extending direction of the sliding guide rod 1113 is parallel to the X-axis.

[0079] The first clamping part 1111 and the second clamping part 1112 are respectively connected to the telescopic cylinder 112, and the telescopic cylinder 112 is adapted to drive the first clamping part 1111 and the second clamping part 1112 to slide.

[0080] The equipment frame is the basic support structure of the entire casting post-processing equipment, used to fix and support various functional components. A Y-axis moving rack 113 is installed on the equipment frame, extending along the Y-axis direction, serving as a guide and transmission reference for the movement of the worktable 11. In conjunction with this, a gear meshing with the Y-axis moving rack 113 and a Y-axis motion motor 114 driving the gear's rotation are mounted on the worktable 11. Specifically, after the Y-axis motion motor 114 starts, its output shaft can drive the transmission gear to rotate via a coupling or reducer. Because the transmission gear remains meshed with the Y-axis moving rack 113 fixed on the equipment frame, the gear's rotational motion is constrained by the Y-axis moving rack 113, thus converting it into linear reciprocating motion of the worktable 11 along the Y-axis direction. This transmission method is a typical "gear-rack linear drive" mechanism, possessing advantages such as high transmission rigidity, fast response speed, good positioning accuracy, and strong load-bearing capacity, capable of meeting the stable operation requirements of the worktable 11 under different working conditions (such as vibration and impact, high-speed movement). This transmission method has a simple structure, reliable operation, and high positioning accuracy, which can ensure that the workbench 11 accurately transports the casting to the preset workstations such as the vibration desanding area, cleaning area, and riser cutting area, realizing the automated connection of multiple processes and significantly improving production continuity and operation efficiency.

[0081] The workpiece clamping table 111 is used to support and fix the casting body, and includes a first clamping part 1111, a second clamping part 1112, and a sliding guide rod 1113. The sliding guide rod 1113 is fixed on the worktable 11, and its extension direction is parallel to the X-axis. The first clamping part 1111 and the second clamping part 1112 are slidably connected to the sliding guide rod 1113 through sliders or linear bearings, forming an adjustable clamping structure. The two clamping parts move relative to each other in the X-axis direction, thereby changing the clamping distance to adapt to the clamping requirements of castings with different widths. The movement of the clamping parts can be achieved by the aforementioned telescopic cylinder 112, forming an automatic adjustment function.

[0082] This equipment features dual functions: precise automatic positioning of the worktable 11 in the Y-axis direction and adaptive adjustment of the workpiece clamping table 111 in the X-axis direction. The transmission between the Y-axis rack and pinion ensures efficient and stable transport of castings between different work areas, avoiding errors and safety hazards caused by manual handling or hoisting. The workpiece clamping table 111 employs a split-type dual-clamping structure guided by a sliding guide rod 1113, giving the equipment excellent versatility and enabling rapid adaptation to various casting specifications, reducing changeover and adjustment time, and improving production flexibility. The sliding guide rod 1113 provides rigid support and guiding accuracy, ensuring a smooth and reliable clamping process. Combined with the casting clamping device 1110, it effectively prevents loosening or displacement of castings during vibration and cutting, improving processing safety and product quality consistency.

[0083] When the first clamping part 1111 and the second clamping part 1112 clamp the casting body, a lateral or annular open gap is naturally formed between its outer side and the worktable 11 or equipment base. This gap serves as a sand drop channel during the vibration sand removal process, allowing the molding sand that falls off from the bottom and sides of the casting to fall smoothly to the waste sand recycling mechanism 15 below, thus avoiding the accumulation of sand particles in the clamping area, which could cause jamming or wear.

[0084] Secondly, the structure can dynamically adjust the clamping distance according to the width of the casting, and can be adapted to various specifications of castings without changing the fixture, which significantly improves the versatility of the equipment and the flexibility of production.

[0085] Most importantly, when the vibratory desanding mechanism 12 applies a high-frequency impact load to the casting, the vibration energy is transmitted through the casting to the clamping parts on both sides. Since the clamping parts are independent movable structures, the vibration impact is converted into an instantaneous tendency force that causes the two clamping parts to move away from each other along the X-axis. The guiding system composed of the telescopic cylinder 112 and the sliding guide rod 1113 generates damping and elastic return during this process, thereby absorbing and dissipating part of the vibration energy, effectively reducing the transmission of vibration to the worktable 11 and the equipment frame, and playing a mechanical buffering and vibration isolation role. This not only improves the overall stability of the machine operation, but also reduces the risk of component fatigue damage caused by resonance.

[0086] like Figure 1 As shown, in some embodiments of this application, the vibration sand removal mechanism 12 includes a gantry tilting bracket 121, an air hammer 122 and a tilting cylinder 123. The air hammer 122 is mounted on the gantry tilting bracket 121, and the telescopic end of the tilting cylinder 123 is hinged to the gantry tilting bracket 121.

[0087] The gantry tilting bracket 121 is hinged to the equipment frame, and the fixed end of the tilting cylinder 123 is hinged to the equipment frame.

[0088] Among them, the air hammer 122 is suitable for applying vibration force to the casting body to achieve dry sand removal of the casting body.

[0089] The air hammer 122 is fixedly installed on the gantry tilting bracket 121. As the core actuator that generates high-frequency vibration force, it is used to apply impact vibration to the surface of the casting body, so that the attached molding sand falls off under the action of mechanical vibration, thus realizing dry sand removal.

[0090] The gantry tilting support 121 is rotatably connected to the equipment frame via a hinge shaft, forming a gantry structure that can rotate around a fixed fulcrum. The fixed end of the tilting cylinder 123 is hinged to the equipment frame, and its telescopic end (piston rod) is hinged to the arm of the gantry tilting support 121. When the tilting cylinder 123 extends or retracts, it pushes the gantry tilting support 121 to rotate around the hinge point, thereby enabling the entire support and the air hammer 122 mounted on it to switch between "open" and "closed" positions: during the loading and unloading stages, the tilting cylinder 123 retracts, and the gantry tilting support 121 opens, providing ample space for casting hoisting; during the desanding stage, the tilting cylinder 123 extends, driving the gantry tilting support 121 to close and position, allowing the air hammer 122 to accurately align with the key parts of the casting, and then the air hammer 122 is activated to perform multi-point synchronous vibration, efficiently removing molding sand.

[0091] Furthermore, the gantry tilting support 121 is not only hinged to the equipment frame, but its structure is also connected to the protective cover surrounding the equipment. This connection design allows the high-frequency impact load generated by the air hammer 122 during the vibratory sand removal process to be transmitted simultaneously to both the equipment frame and the protective cover through the gantry tilting support 121, forming a dual-path vibration diversion structure. Since the protective cover is typically composed of a rigid frame and sound-absorbing and insulating materials, it has a certain mass and damping characteristics, effectively participating in the absorption and dissipation of vibration energy. This significantly reduces the peak load borne by a single structure (such as only the frame), alleviates local stress concentration, improves the overall operational stability of the machine, and extends the service life of key components.

[0092] More preferably, the tilting cylinder 123 is equipped with a buffer device, such as a hydraulic buffer or a pneumatic-hydraulic damper, located at the end of its piston rod stroke or inside the cylinder body. When the gantry tilting support 121 completes its closing or opening action under the drive of the tilting cylinder 123, the buffer device can progressively decelerate and brake the piston at the end of the movement, effectively suppressing the instantaneous impact force generated by high-speed impact and preventing mechanism rebound, abnormal noise, or loosening of connecting parts. This buffering measure works synergistically with the aforementioned vibration diversion structure to weaken the impact of vibration from both the source reduction and path load distribution dimensions, significantly improving the dynamic performance and operational reliability of the equipment.

[0093] Employing a tilting gantry structure, the equipment opens its working area when not in operation, significantly improving the ease of loading and unloading castings, especially suitable for clamping large or complex-shaped castings. The tilting cylinder 123 is hinged at both ends, working in conjunction with the adjustable workpiece clamping table 111 on the worktable 11, forming the basis for the equipment's compatibility with castings of various specifications and sizes. Vibration loads are transferred to the overall equipment frame through the gantry frame, preventing localized structural overload and improving equipment rigidity and service life.

[0094] By directly striking the casting with a high-frequency air hammer 122 or transmitting vibration through a support, more than 90% of the molding sand can be removed without water washing. The resulting waste sand is in a dry state, which is easy to recycle and reduces environmental treatment costs.

[0095] In addition, the gantry tilting action is automatically controlled by the tilting cylinder 123, which can be linked with the movement and clamping device of the worktable 11 and coordinated by the PLC to realize the fully automatic process of "feeding → clamping → tilting and closing → vibration and sand removal → tilting and opening → unloading", thereby improving production efficiency and safety.

[0096] like Figures 1 to 3 As shown, in some embodiments of this application, the casting cleaning mechanism 13 includes a cleaner 131 and a rotary motor 132;

[0097] The cleaner 131 is located below the workbench 11, and the rotary motor 132 is adapted to drive the cleaner 131 to rotate axially to adjust the spray angle.

[0098] The cleaner 131 is the core component for performing cleaning operations. It has a high-pressure flow channel 133 and a specially designed nozzle inside, which is used to spray high-pressure liquid (such as water or cleaning fluid) onto the surface and inner cavity of the casting to remove the small amount of molding sand remaining on the casting after vibration sand removal, especially residual sand particles in complex inner cavities and dead corners that are difficult to be completely removed by vibration.

[0099] The cleaner 131 is located below the worktable 11 and is arranged in a bottom-up manner, enabling reverse jet cleaning of the casting's interior through openings at the bottom (such as inner cavities or bottom through holes). This layout makes full use of the positioning space of the casting on the worktable 11, avoids interference with the upper vibration and cutting mechanisms, and facilitates multi-position cleaning in conjunction with the Y-axis movement of the worktable 11 during the cleaning process.

[0100] The rotary motor 132 is connected to the cleaner 131 and is suitable for driving the cleaner 131 to rotate around its axis and controlling its spray angle. Through the precise control of the rotary motor 132, the cleaner 131 can achieve continuous rotation or reciprocating oscillation during the cleaning process, so that the high-pressure water flow covers the inner wall of the casting in a multi-angle, spiral or fan-shaped trajectory, which significantly improves the uniformity and thoroughness of cleaning and effectively avoids cleaning blind spots.

[0101] A cleaning mounting base 134 can also be set. The cleaning mounting base 134 is the core support component of the cleaning system. It is fixedly installed in the non-moving area at the bottom of the equipment frame or under the workbench 11. It is used to support and position the cleaner 131 and the rotary motor 132 assembly, ensuring that they remain stable during high-pressure rinsing and avoiding displacement or loosening due to vibration or liquid flow reaction force.

[0102] like Figure 1 As shown, in some embodiments of this application, the riser cutting mechanism 14 includes a cutting motor 141, an X-axis moving table 142, and a saw blade 143;

[0103] The cutting motor 141 is mounted on the X-axis moving table 142 and is adapted to drive the saw blade 143 to rotate.

[0104] The saw blade 143 is the tool that directly performs the cutting. It is mounted on the output spindle of the cutting motor 141 and rotates at high speed to cut into the riser area of ​​the casting, achieving a smooth and precise cut. The saw blade 143 is usually made of cemented carbide or diamond, which has good wear resistance and thermal stability, and is suitable for cutting castings of various materials such as cast iron and cast steel.

[0105] The cutting motor 141, serving as the power source, is fixedly mounted on the X-axis moving stage 142. Its output end can be connected to the spindle of the saw blade 143 via a flange or a standard interface such as BT40, providing stable, high-speed rotational power to the saw blade 143. The cutting motor 141 can be a frequency converter motor or a servo motor, with adjustable speed to control the linear speed of the saw blade 143, ensuring efficient and low-damage cutting under different material and thickness conditions.

[0106] The X-axis moving table 142, which is servo-controlled, works in conjunction with the high-speed rotating saw blade 143 to achieve precise feed and stable cutting, resulting in a smooth cut without burrs or flash, thus reducing subsequent finishing processes.

[0107] The entire cutting process is automatically controlled by the control system. The X-axis feed is linked with the Y-axis positioning of the worktable 11. The cutting path can be preset to achieve multi-point and multi-segment automatic cutting, which significantly improves production efficiency.

[0108] like Figure 1 As shown, in some embodiments of this application, a motor mounting base is provided at the bottom of the cutting motor 141, and a slider is provided on the motor mounting base;

[0109] The X-axis moving stage 142 includes an X-axis motion motor 1421 and a lead screw 1422, with a slider slidably connected to the lead screw 1422.

[0110] X-axis motion motor 1421 is suitable for driving lead screw 1422 to rotate;

[0111] The cutting line speed of saw blade 143 ranges from 75 m / s to 100 m / s.

[0112] The bottom of the cutting motor 141 is provided with a motor mounting base, which is used to securely mount the cutting motor 141 onto the motion mechanism. As a key structural component connecting the cutting motor 141 and the X-axis moving stage 142, the motor mounting base not only plays a supporting and positioning role, but also ensures that the cutting motor 141 maintains a rigid connection during high-speed operation and feeding, avoiding vibration or displacement from affecting the cutting accuracy.

[0113] A slider, which can be a linear guide slider, is installed on the motor mounting base. It cooperates with the guide rail fixed on the equipment frame to form a guide system in the X-axis direction. The slider slides along the guide rail with the motor mounting base, providing high-precision, low-friction linear guidance for the feed motion of the cutting motor 141. This ensures that the saw blade 143 runs smoothly and accurately during the cutting process, effectively preventing skewing or damage to the saw blade 143 due to wobbling.

[0114] The X-axis moving stage 142 includes an X-axis motion motor 1421 and a lead screw 1422 (usually a ball screw or trapezoidal lead screw). The lead screw 1422 is arranged along the X-axis direction, and one or both ends are supported by bearing seats to form a stable transmission shaft system. The slider is connected to the nut on the lead screw 1422 through a slide block. When the X-axis motion motor 1421 is started, its output shaft drives the lead screw 1422 to rotate through a coupling or synchronous belt. The helical pair between the lead screw 1422 and the nut converts the rotational motion into linear motion, thereby driving the slider, motor mounting base, and the cutting motor 141 mounted thereon to move precisely back and forth along the X-axis direction.

[0115] The X-axis motion motor 1421 is suitable for driving the lead screw 1422 to rotate. It is usually a servo motor or a stepper motor and has precise position and speed control capabilities. By setting the feed speed, stroke and start / stop timing through the PLC control system, the cutting process can be automated, such as slow entry, fast feed, and stop at the end, to meet the needs of cutting risers of castings of different materials and thicknesses.

[0116] The transmission combination of "servo motor + ball screw + linear guide slider" is adopted to achieve micron-level positioning accuracy, ensure the accuracy of the cutting path of saw blade 143, and improve the consistency of cut quality.

[0117] The cutting linear speed range of saw blade 143 is 75 m / s to 100 m / s. This linear speed refers to the tangential speed reached by the outer edge of saw blade 143 during high-speed rotation, and is a key process parameter affecting cutting efficiency, cut quality, and saw blade 143 lifespan. By properly matching the speed of cutting motor 141 with the diameter of saw blade 143, the linear speed of saw blade 143 during operation can be stabilized within this range, enabling efficient and stable cutting of common cast metal materials such as cast iron and cast steel.

[0118] Within this speed range, the saw blade 143 can cut into the metal riser with sufficient kinetic energy, effectively reducing cutting resistance and wear on the saw blade 143. It also avoids safety hazards such as decreased cutting efficiency or increased burrs due to excessively low speed, and increased vibration, excessive temperature rise, and saw blade 143 breakage caused by excessively high speed. Especially for thick risers on large castings, high linear velocity can significantly increase cutting speed and shorten the processing time per piece.

[0119] Furthermore, this linear speed range is matched to the material properties of commonly used carbide or diamond segment saw blades 143, fully leveraging their wear resistance and impact resistance to extend tool life and reduce replacement frequency and maintenance costs. Combined with the precise feed control of the X-axis moving table 142, continuous and stable automated operation can be achieved while ensuring cutting quality.

[0120] like Figure 1 , Figures 4 to 6 As shown, in some embodiments of this application, it further includes: a waste sand recycling mechanism 15, which is disposed below the vibrating sand removal zone and is suitable for collecting and transferring the waste sand from the vibrating sand removal zone;

[0121] The riser recovery mechanism 16 is located below or to the side of the cutting riser area and is suitable for collecting and transferring the sawn material from the cutting riser area.

[0122] The waste sand recycling unit 15 is used to collect and transport the molding sand that falls off during the vibration sand removal process, preventing it from accumulating inside the equipment or spreading to the working environment. The fallen dry sand can be continuously transported to the recycling bin for centralized storage. The entire process requires no manual intervention, realizing automatic and closed-loop recycling of waste sand, keeping the site clean, and facilitating subsequent resource recovery.

[0123] The riser recycling mechanism 16 is used to collect metal shavings and sawn riser material generated during the riser cutting process, to avoid shavings scattering and causing safety hazards or environmental pollution, to realize automatic classification, collection and centralized transfer of metal waste, and to improve resource recycling efficiency.

[0124] like Figure 1 , Figures 4 to 6 As shown, in some embodiments of this application, the waste sand recycling mechanism 15 includes a belt conveyor 151 and a waste sand recycling bin 152;

[0125] The conveying path of the belt conveyor 151 includes: a discharge end that extends obliquely upward from below the bottom of the equipment to the outside of the equipment; the feed end of the belt conveyor 151 is located directly below the vibrating sand removal zone and is used to receive waste sand that falls off from the casting body; and the discharge end extends above the waste sand recovery box 152.

[0126] The belt conveyor 151 is the core component for waste sand conveying. Its conveying path adopts a bottom-up inclined structure design: the feed end is located below the bottom of the equipment and directly faces the area below the vibrating sand removal zone, which can directly receive the dry waste sand that falls freely from the surface and inner cavity of the casting due to vibration and passes through the gap of the workbench 11 or the guide channel; the conveying path extends upward at an incline until the discharge end extends outside the equipment, which is convenient for docking with external material containers; the discharge end is set above the waste sand recycling box 152, so that the waste sand conveyed to the end falls naturally into the box under the action of gravity, completing the automatic discharge.

[0127] The belt conveyor 151 can use wear-resistant rubber belts or metal mesh belts, possessing excellent wear resistance and load-bearing capacity, and can operate stably for a long time in dusty, intermittent feeding conditions. The conveyor belt is driven by a motor-driven drum, and the motor can be linked with the main control system of the equipment, automatically starting after the vibration and sand removal process is initiated, realizing an energy-saving "material-on-demand" operation mode.

[0128] The waste sand recovery bin 152 is a detachable container located outside the equipment for easy forklift or manual handling. Its top opening corresponds to the discharge end of the belt conveyor 151, and it is used to receive continuously discharged dry waste sand. Due to the use of a dry sand removal process, the recovered waste sand has extremely low moisture content and basically maintains its original sand particle state, which is beneficial for subsequent waste recycling and processing.

[0129] like Figure 1 , Figures 4 to 6 As shown, in some embodiments of this application, the riser recovery mechanism 16 includes a chip conveyor 161 and a riser recovery box 162;

[0130] The chip conveyor 161 is located below the cutting riser area, and the feed end of the chip conveyor 161 is located directly below the cutting station. It is used to collect the metal risers and chips generated during the sawing process.

[0131] The discharge end of the chip conveyor 161 extends above the riser recovery box 162.

[0132] The chip conveyor 161 is located below the cutting riser area and serves as the core device for conveying metal scrap. Its feed end is located directly below the cutting station, enabling it to directly receive high-temperature metal chips, sawn material, and intact riser blocks falling from the cutting area of ​​the saw blade 143. During the cutting operation, the generated metal scrap falls naturally into the conveying trough of the chip conveyor 161 through the pre-reserved discharge port or guide channel at the bottom of the equipment, preventing scrap from accumulating inside the equipment and affecting normal operation or causing safety hazards.

[0133] The chip conveyor 161 can adopt a scraper, spiral, or chain plate structure, possessing strong conveying capacity and impact resistance, and is especially suitable for the continuous conveying of large-particle, high-hardness metal scrap. Its conveying process can be driven by an independent motor and linked to the cutting riser mechanism 14: when the cutting process starts, the chip conveyor 161 starts synchronously or with a delay to ensure that scrap is promptly removed as soon as it is generated; after cutting, it automatically stops after a delay to ensure that any residual scrap in the conveying trough is completely discharged.

[0134] The discharge end of the chip conveyor 161 extends upwards and beyond the equipment, eventually reaching above the riser recovery box 162. After being conveyed to the discharge end by the chip conveyor 161, the waste falls into the riser recovery box 162 under gravity for centralized storage. This design achieves a closed-loop treatment process of "on-site collection - automatic conveying - fixed-point discharge," eliminating the need for frequent manual cleaning of the cutting area and significantly improving operational efficiency and site cleanliness.

[0135] The riser recycling box 162 is a movable or detachable container, usually equipped with rollers or a lifting structure, which facilitates its transfer to the centralized metal scrap processing area by forklift or overhead crane when fully loaded. Since the main component of the riser is reusable metal material, it can be directly sent to the smelting furnace for remelting after recycling, realizing resource recycling and reducing raw material costs.

[0136] like Figure 7 As shown, a second aspect of this application provides a casting post-processing method based on the casting post-processing equipment in any of the first aspects described above, comprising:

[0137] Step 100: Place the casting body to be processed on the worktable 11.

[0138] Step 200: Control the workbench 11 to transport the casting body to the vibration desanding zone, and control the vibration desanding mechanism 12 to apply vibration force to the casting body to achieve dry desanding of the casting body.

[0139] Step 300: Control the workbench 11 to move the casting body that has completed dry sand removal along the Y-axis towards the cutting riser area. During the movement, start the casting cleaning mechanism 13 located below the workbench 11 to perform liquid spray cleaning on the casting body to remove residual sand.

[0140] Step 400: After the casting body reaches the cutting riser zone, control the cutting riser mechanism 14 to cut the redundant part of the casting body.

[0141] Based on the above, the specific work process is as follows:

[0142] First, the worktable 11 moves to the initial loading position. The first clamping part 1111 and the second clamping part 1112 of the workpiece clamping table 111 are driven to slide along the X-axis by the telescopic cylinder 112, adjusting the clamping distance to fit the width of the current casting, thus preparing for loading. The operator or automatic loading device places the casting body onto the workpiece clamping table 111.

[0143] Subsequently, the telescopic cylinder 112 continues to operate, pushing the clamping part closer to the center, and causing the casting clamping devices 1110 on both sides of the casting to clamp and fix the casting, ensuring its stability during subsequent processing. At this time, the gantry tilting bracket 121 of the vibration desanding mechanism 12 rotates around the hinge point under the drive of the tilting cylinder 123, driving it to close to the working position, so that the multiple air hammers 122 mounted on it are accurately aligned with the surface of the casting.

[0144] The pneumatic hammer 122 is activated, applying high-frequency vibration to the casting. Combined with the casting's own rigid structure, this causes most of the molding sand adhering to the surface and inner cavity to fall off, achieving efficient dry sand removal. After vibration is complete, the gantry tilting support 121 is tilted open by the tilting cylinder 123, returning to a non-interference position.

[0145] Next, driven by the Y-axis motion motor 114, the worktable 11, through gear meshing with the Y-axis moving rack 113 on the equipment frame, drives the casting to move smoothly along the Y-axis from the vibration desanding zone to the cutting riser zone. During this conveying process, the cleaner 131, located below the worktable 11, starts working, forming a dynamic processing mode of "moving and cleaning simultaneously". Driven by the rotary motor 132, the cleaner 131 adjusts the spray angle and sprays high-pressure liquid from the bottom opening of the casting to clean it from multiple angles, effectively removing the fine sand particles remaining after vibration.

[0146] As the worktable 11 continues to move along the Y-axis to the riser cutting area, the riser cutting mechanism 14 is activated: the X-axis motion motor 1421 drives the lead screw 1422 to rotate, which in turn drives the slider and the cutting motor 141 mounted on it to feed along the X-axis. The cutting motor 141 drives the high-speed saw blade 143 (linear speed 75~100m / s) to rotate, and precisely saws off the excess metal parts such as the gating and riser on the casting.

[0147] During or after sawing, the worktable 11 begins to return outward along the Y-axis, moving towards the discharge direction. During this return journey, the cleaner 131 can be restarted to perform a secondary rinse on the cut area or the entire casting, further improving cleanliness.

[0148] This equipment is particularly suitable for the post-processing of tire mold castings. These castings typically have only one side in contact with the mold, and their complex structure, deep cavities, and concentrated residual sand in specific areas are all characteristic features. This equipment, through an integrated process of "dry vibration + bottom reverse flushing + automatic cutting + waste sorting and recycling," can efficiently remove molding sand from critical areas and precisely cut off risers, avoiding damage to the working surface while maintaining the original state of non-contact surfaces. This is especially suitable for the cleaning process requirements of tire mold castings.

[0149] like Figures 4 to 6 As shown, in addition to reducing noise pollution during equipment operation and ensuring operator safety, the equipment also includes a soundproof room system and a full protection system to achieve enclosed operation and intelligent safety interlock control.

[0150] The soundproof room 17 is a multi-layered composite structure, consisting of a feed door, maintenance door 173, observation window, dust removal interface and lighting system, etc. It is used to isolate high-noise processes such as vibration and cutting, and ensure that the noise of the external working environment is controlled below 85dB(A), which meets occupational health and safety standards.

[0151] The main structure of soundproof room 17 uses a high-strength square steel frame as its support structure, covered with a 100 mm thick steel plate to form a rigid outer shell. The inner layer is a perforated steel sound-absorbing panel with acoustically optimized hole diameter and spacing to effectively reduce mid-to-high frequency noise reflection. High-efficiency sound insulation and sound-absorbing materials (such as centrifugal glass wool or rock wool) are filled between the inner and outer layers to form a composite sound-absorbing layer, significantly improving the overall sound insulation performance. Soundproof room 17 has anchor bolt holes at its four corners for easy fixing to the ground, enhancing structural stability and preventing resonance during equipment operation.

[0152] The front of the soundproof chamber 17 is equipped with a left-right opening automatic door 171 for loading and unloading castings. The door body adopts a double-layer steel plate sandwich structure, which matches the sound insulation performance of the main body of the soundproof chamber. The automatic door 171 is equipped with a drive motor and guide rail system to achieve smooth opening and closing. A position sensor is installed behind the loading door to detect whether the door is fully closed, ensuring that the equipment starts high-noise processes (such as vibration sand removal) only when the door is closed, preventing noise leakage.

[0153] The feed door is equipped with a double-glazed observation window 172 in the middle. The interlayer is hollow or filled with inert gas, which has good sound insulation and heat insulation performance. Operators can monitor the internal operating status of the equipment in real time through the observation window and complete the process inspection without opening the door.

[0154] The soundproof room 17 is equipped with manual maintenance doors 173 on the left and rear sides for daily maintenance and inspection. All doors are equipped with sealing strips to ensure the overall airtightness of the soundproof room 17.

[0155] The soundproof room 17 is equipped with a dust collection connection flange on the top, which can be connected to an external central dust collection system to collect dust and fine particles generated during equipment operation, keeping the indoor air clean. The room is also equipped with an explosion-proof lighting system to ensure sufficient light even in a closed environment, facilitating operation and monitoring at night or in low-light conditions.

[0156] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0157] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0158] The above description is merely an embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
