Detailed Implementation

[0047] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0048] Example 1

[0049] A specific embodiment of the present invention, such as Figure 1 As shown, a casting forming system is disclosed, including a casting forming device 1, a cleaning device 2, and a cutting and grinding device 3.

[0050] The casting forming device 1 is used for casting forming of castings; the casting forming device 1 includes a wax pattern forming unit, a shell forming unit 12 and a casting forming unit.

[0051] The cleaning device 2 is used to clean the mold shell 4 and iron wire in the casting; the cutting and grinding device 3 is used to cut and grind the cleaned casting.

[0052] The casting forming system in this embodiment integrates a casting forming device 1, a cleaning device 2, and a cutting and grinding device 3, which are used for casting forming, cleaning the mold shell 4 after casting, and cutting and grinding of the casting, respectively, forming a continuous production chain and significantly shortening the production cycle of a single product. The precision casting produced by the casting forming device 1, the cleaning device 2 cleaning the casting mold shell 4, and the cutting and grinding device 3 realizing the post-processing of the casting are all coordinated with each other, enabling the system to adapt to the production needs of various castings, improving production flexibility, and realizing high efficiency, precision, and large-scale casting production, which is especially suitable for the manufacturing needs of mass production or precision castings.

[0053] Specifically, such as Figure 2 As shown, the casting forming device 1 includes a wax pattern forming unit, a shell forming unit 12, and a casting forming unit.

[0054] The wax model forming unit includes a wax press 11, which is used to press wax into the shape of the workpiece to form a wax model.

[0055] The shell forming unit 12 includes a slurry dipping tank 121, a sandblasting machine 122, a drying oven 123, and a dewaxing device 124. The slurry dipping tank 121, sandblasting machine 122, and drying oven 123 are used to coat the surface of the wax model with slurry, sandblast, and dry it to form a shell 4 on the surface of the wax model. The dewaxing device 124 is used to melt the wax model in the shell 4. Exemplarily, the dewaxing device 124 is one of a steam dewaxing kettle, an oven, or a dewaxing roasting furnace.

[0056] The casting forming unit includes a vacuum induction melting furnace 13, which is used to pour the molten alloy into the mold shell 4 to form the casting. The vacuum induction melting furnace 13 heats, melts, and refines metals or alloys in a vacuum environment using the principle of electromagnetic induction, ultimately obtaining high-purity, uniformly composed metal billets or castings. It can efficiently remove gaseous impurities and realize the preparation of complex alloy proportions.

[0057] like Figure 3 As shown, the cleaning device 2 includes a shell cleaning unit 21, a waste separation unit, and a conveying unit 24.

[0058] like Figure 4 As shown, the shell cleaning unit 21 includes a hydraulic crushing robotic arm 211, a manual shell cleaning device, and a high-pressure water shell cleaning device. The hydraulic crushing robotic arm 211 uses a hydraulically driven hydraulic hammer to crush the shell 4 on the surface of the casting, replacing manual methods and improving shell cleaning efficiency. The robotic arm has the ability to move flexibly through multiple joints, and can adjust its posture according to the shape of the casting and the attachment position of the shell 4. By controlling the hydraulic pressure, the crushing force can be adjusted to avoid damaging the casting body while crushing the shell 4; and by adjusting the pressure and angle, it can adapt to cleaning shells 4 of different thicknesses and hardnesses.

[0059] The manual shell removal equipment includes a pneumatic pick, used to remove the manually removed shell after the hydraulic crushing robotic arm 211 has vibrated and cleaned it. The pneumatic pick is used manually to peel the wire and mold shell 4 from the casting.

[0060] The high-pressure water cleaning equipment includes a high-pressure water device 212, a six-axis robot 213, a gantry robot 215, and a gantry 214.

[0061] The high-pressure water jet device 212 has adjustable pressure and flow rate. It uses high-pressure water to spray onto the surface of the casting to remove the shell 4. When the impact force generated by the high-speed jet on the shell 4 exceeds its shear strength, the shell 4 is broken up. The water then seeps into the cracks in the shell 4, disrupting the bonds between the shells. The shell 4 is then dispersed and washed off with the water flow. A six-axis robot 213 is connected to the high-pressure water jet device 212 to control its high-pressure water jet, achieving high-pressure water shell removal from the casting. The six-axis robot 213 controls the high-pressure water jet to operate automatically according to a program, automatically adjusting the water pressure and flow rate during the shell removal process to achieve automatic high-pressure water shell removal from the casting. The high-pressure water nozzle, in conjunction with the six-axis robot 213, thoroughly removes residual shell 4 from blind holes, grooves, and internal cavities.

[0062] A gantry robot 215, mounted on a gantry 214, is used to transport the shell 4 and castings to the workstation of the six-axis robot 213. The gantry 214 includes X, Y, and Z axes. The gantry robot 215 includes a flipping structure, a rotating structure, and an end effector for gripping, flipping, and rotating the shell 4. The movement, swinging, and rotation of the X, Y, and Z axes of the gantry robot 215 are all achieved by servo motors driving rack and pinion transmission, with a repeatability accuracy of ≤±5mm, ensuring smooth and flexible movement of the gantry robot 215. The end effector of the gantry 214 can handle the gripping and flipping of different shells 4. The gripping fixture is driven by a servo motor and uses a pin-type positioning system, enabling quick, simple, and secure clamping.

[0063] In this embodiment, the vibratory shell cleaning first uses the hydraulic crushing robot arm 211 for mechanical cleaning, reducing the intensity of manual processing and weakening the force between the casting and the shell 4. Then, a manual pneumatic pick is used for targeted cleaning to peel the shell 4 from the wire mesh, avoiding mechanical removal that could damage the casting. Subsequently, a gantry robot arm 215 and a six-axis robot arm 213 are used for high-pressure water shell cleaning to improve the shell cleaning efficiency.

[0064] The waste separation unit is used to separate iron wire and shell blocks from the waste residue of vibratory shell cleaning and manual pneumatic hammer shell cleaning, and to separate shell blocks and water from the waste residue of high-pressure water shell cleaning.

[0065] Specifically, the waste residue separation unit includes a first waste residue separation unit 22. The first waste residue separation unit 22 is located below the vibratory shell cleaning and manual pneumatic hammer shell cleaning station.

[0066] like Figure 5 As shown, the first waste separation unit 22 includes a first filter device 221 inclined at the top and a first slag collector 222 disposed at the bottom of the first filter device 221. The first filter device 221 is used to filter the shell blocks and recover the iron wire; the first slag collector 222 is used to collect the shell blocks filtered by the first filter device 221.

[0067] Specifically, the mesh of the first filter device 221 is a diamond-shaped structure. The end of the first filter device 221 has a wire collecting groove 2214 for collecting wires.

[0068] A rebound plate 2211 is vertically installed at the end of the first filtration device 221. The first filtration device 221 is inclined so that when the wire and large shell pieces slide down from the middle or starting end of the first filtration device 221 to the rebound plate 2211, the rebound plate 2211 rebounds the unbroken large shell pieces back to the middle or starting end, where they slide down again to the rebound plate 2211 and break upon impact, while the wire remains unchanged after rebounding. Furthermore, the rebound plate 2211 is made of rubber.

[0069] Furthermore, the first filter device 221 has slide rails on both sides of its end, and the rebound plate 2211 can move on the slide rails to remove or block the waste residue from falling. The rebound plate 2211 is inserted downward into the slide rail to the end of the first filter device 221, preventing the waste residue from sliding into the guide plate and into the collection basket. When the rebound plate 2211 is pulled out from the slide rail, the wire in the first filter device 221 slides down and slides into the collection basket from the guide plate.

[0070] In this embodiment, the rebound plate 2211 is set so that the molded shell blocks and large molded shell blocks on the iron wire are broken and enter the first slag collector 222 through the mesh of the first filter device 221, and are collected by the first slag collector 222, thereby improving the waste slag treatment efficiency and reducing the difficulty of separating the iron wire from the molded shell 4.

[0071] Furthermore, in order to prevent the shell block from clogging the mesh of the first filter device 221, the first filter device 22161 is provided with an impact structure 2213, which causes the shell block that is clogging the mesh to pop out by impacting the first filter device 221 and participate in the rebound and breaking.

[0072] The impact structure 2213 is disposed on one side of the first filter device 221. Exemplarily, the impact structure 2213 includes an eccentric wheel, a first connecting rod, a second connecting rod, a straight rail, an impact hammer, and a return spring.

[0073] The eccentric wheel is driven by a motor at its center. A groove is provided near the edge of the eccentric wheel. One end of the first connecting rod is located in the first groove and can move within the first groove.

[0074] The other end of the first link is connected to the second link. The second link is mounted on a straight rail and can slide within it. Thus, the second link converts the rotational motion of the eccentric wheel into linear motion along the straight rail. The impact hammer is mounted on the other end of the second link and moves linearly along with it. Furthermore, to ensure rapid reset after impact, a spring is installed between the second link and the impact hammer.

[0075] Furthermore, the first filtration device 221 also has a tilting structure 2212, which is located on the other side of the first filtration device 221. The tilting structure 2212 is used to tilt the iron wire in the first filtration device 221 and accelerate the impact of the shell block in the first filtration device 221 onto the rebound plate 2211 by repeatedly changing the tilt angle, thereby improving the crushing efficiency of the shell block.

[0076] Exemplarily, the tilting structure 2212 includes a telescopic cylinder, an L-shaped rod, and a swing rod. One end of the L-shaped rod is connected to the cylinder, and the other end is connected to the swing rod. The other end of the swing rod is hinged to the first filter device 221.

[0077] The extension and retraction of the telescopic cylinder drives the rotation of the L-shaped rod, which in turn causes the swing arm to oscillate, thus changing the angle between the first filtration device 221 and the horizontal plane. Furthermore, the L-shaped rod limits the tilt angle of the first filtration device 221 to less than 90°. As the angle between the first filtration device 221 and the horizontal plane increases, the speed and force of the shell block impacting the rebound plate 2211 increase, thereby improving the efficiency of shell 4 crushing.

[0078] It should be noted that the striking structure 2213 is driven by a motor, which is electrically connected to the host computer of the shell 4 cleaning device 2 and is controlled by the host computer. This is existing technology and will not be described in detail here.

[0079] The first slag collector 222 has a fixed tilt angle and a first guide box 2215 is provided at its end for collecting the shell blocks. The first guide box 2215 is located above the conveying mechanism 242. The bottom of the first guide box 2215 is a through hole. After the shell blocks are collected by the first guide box 2215, they fall directly into the conveying mechanism 242.

[0080] The waste separation unit also includes a second waste separation unit 23. For example... Figure 6 As shown, the second waste separation unit 23 is located below the station of the high-pressure water equipment 212. The second waste separation unit 23 includes a second filter device 231 arranged at an incline and a second sludge collector 232 located below the second filter device 231. The second filter device 231 is used to collect small pieces of the shell, and the second sludge collector 232 is connected to the water storage tank 2322.

[0081] Because the shell block of the high-pressure water cleaning shell contains water, it is easily adsorbed by the filtration equipment. Therefore, a scraper 2311 is provided on the second filtration equipment 231.

[0082] The scraper 2311 includes a scraper body and a handle. The shape of the scraper body matches the curvature of the second filter device 231 to facilitate pushing the shell blocks into the second guide box 2221 at the end. The second guide box 2221 is located above the conveying mechanism 242. The bottom of the second guide box 2221 is a through hole, and the shell blocks are collected through the second guide box 2221 and fall directly into the conveying mechanism 242. The second slag collector 232 has a liquid collection tank 2321 at its end, which is connected to a water storage tank 2322.

[0083] The end of the handle is connected to a telescopic cylinder, and the scraper 2311 moves on the second filter device 231 by the telescopic movement of the end of the telescopic cylinder.

[0084] During the removal process, some iron filings are generated. A magnet 2312 is installed on the upper part of the scraper 2311, and the magnet 2312 is located at the end of the rod. The middle part of the rod is hinged to the upper part of the scraper 2311. The rod can move with the scraper 2311 and can rotate at multiple angles to attract the iron filings from the iron wire.

[0085] It should be noted that the second filter device 231 and the scraper 2311 are both made of non-ferrous materials. In this embodiment, the first filter device 221, the second filter device 231, the first slag collector 222, and the second slag collector 232 are all arc-shaped structures for easy collection.

[0086] like Figure 7 As shown, the conveying unit 24 includes a waste discharge port and a waste pusher plate, which pushes the waste to the discharge port. The waste pusher plate is mounted on the floor of the space between the hydraulic crushing robot arm 211, the pneumatic pick, and the high-pressure water cleaning station. The waste discharge port is located on one side of the station. The height of the waste discharge port is lower than the height of the station, facilitating waste collection.

[0087] The conveying unit 24 also includes a material basket 241, a conveying mechanism 242, and a lifting mechanism 243.

[0088] A conveying mechanism 242 is located below the waste discharge port, and a material basket 241 is located at the end of the conveying mechanism 242. The conveying mechanism 242 is used to transport the waste from the waste discharge port to the material basket 241. Furthermore, the material basket 241 is equipped with a weighing sensor to remind the operator to clean the waste. When the weight of the broken shells in the basket exceeds three tons, the weighing sensor uploads the information to the host computer, which then reminds the operator to promptly clean the shells and perform subsequent recycling work. The lifting mechanism 243 is an X-shaped lifting mechanism used to lift the material basket 241 onto a forklift.

[0089] Furthermore, the cleaning device also includes a dust removal unit 25, which includes a dust removal unit and dust removal pipelines. The dust removal pipelines are located in the upper part of the space of the first cleaning unit 21 and adsorb dust by means of negative pressure.

[0090] The cutting and grinding equipment includes an automatic cutting machine and a grinding machine, used to cut and grind the gating gates and other parts of the casting after shell cleaning.

[0091] The molding method in this embodiment is as follows:

[0092] First, the casting is formed. The wax material is pressed into the shape of the workpiece using a wax press 11, and multiple workpiece wax molds are combined. The wax mold is coated with slurry, sanded, and dried to form a shell 4. The wax mold inside the shell 4 is melted using a dewaxing device 124. It should be noted that in order to prevent the shell 4 from cracking and deforming, a wire mesh is inserted inside the shell 4 during the preparation process. The molten alloy is poured into the shell 4, and the shell 4 is placed in a vacuum induction melting furnace 13 for casting to form a casting.

[0093] Next, the shell 4 and wire are cleaned. The hydraulic hammer of the hydraulic crushing robot arm 211 performs preliminary cleaning of the casting shell 4. The cleaned waste is pushed into the shell-breaking discharge port of this station by a pusher plate. The wire and shell blocks are cleaned manually using a pneumatic pick. The cleaned waste is pushed into the waste discharge port of this station by a pusher plate. After preliminary cleaning, the casting is transported by forklift to the high-pressure water shell cleaning unit 21. The casting is placed in the station of the truss structure 214. The end effector of the truss robot arm 215 clamps the casting, the high-pressure water equipment 212 is turned on, and the high-pressure water pressure is adjusted to further clean the remaining casting shell 4. During the cleaning process, the rotation and flipping of the shell 4 are carried out by the flipping mechanism and the rotating mechanism of the truss 214. The cleaned residue enters the waste discharge port of this station.

[0094] The molded shell blocks and wire mesh are pushed by the waste slag pusher plate through the waste slag discharge port into the first waste slag separation unit 22, and fall onto the first filter device 221 in the first waste slag separation unit 22. They slide from the taller end of the first filter device 221 to the shorter end, i.e., the end of the first filter device 221. The rebound plate 2211 of the first filter device 221 rebounds the molded shell blocks and wire mesh to the taller end or the middle. The tilting structure 2212 is activated, causing the wire and molded shell blocks in the first filter device 221 to rebound continuously. The molded shell blocks and large molded shell blocks on the wire mesh are impacted and broken, and fall into the first slag collector 222 through the mesh of the first filter device 221. When the mesh of the first filter device 221 is blocked, the impact structure is activated, and the impact hammer strikes the filter device, causing the molded shell blocks in the filter device holes to break or pop out. The wire enters the wire collection groove 2214 at the end of the first filter device 221.

[0095] The first slag collector 222 has a fixed tilt angle and a first guide box 2215 is provided at the end. The broken pieces of the shell 4 enter the conveying mechanism 242 through the conical guide box.

[0096] After the high-pressure water equipment 212 cleans the molded shell pieces and water, they fall through the waste residue discharge port into the second filter device 231 of the lower second waste residue separation unit 23. Water falls through the mesh of the second filter device 231 into the second slag collector 232, and is collected by the inclined second slag collector 232 into the liquid collection tank 2321, and finally enters the water storage tank 2322 for recycling. The molded shell pieces on the second filter device 231 are moist and slide down the inclined second filter device 231 into the second guide box 2221, and fall into the conveying mechanism 242. The molded shell pieces adhering to the second filter device 231 are pushed by the scraper 2311 into the second guide box 2221 at the end of the second filter device 231. At the same time, the magnet 2312 above the scraper 2311 attracts iron filings.

[0097] The waste slag pusher plate pushes the waste slag to the waste slag discharge port. After entering the waste slag discharge port, the waste slag is transported by the conveying mechanism 242 to the material frame of the lifting mechanism 243. The material frame of the lifting mechanism 243 can hold about four tons of waste slag. When the weight of the broken shells in the material frame exceeds three tons, the host computer reminds the operator to promptly clean the shells and carry out subsequent recycling work.

[0098] Next, the castings are cut and ground. Forklifts are used to transport the castings to the cutting and grinding stations, where automatic cutting and grinding machines are used to cut and grind the gating gates and other parts of the castings.

[0099] Finally, the casting is machined and shaped.
