Description

Technical Field

[0001] This invention relates to the field of intelligent casting island technology, and in particular to an intelligent casting island for a magnetic levitation vacuum pump housing. Background Technology

[0002] In the manufacturing of magnetic levitation vacuum pumps, the casting of the outer casing is a crucial step determining product performance and cost. Currently, the industry commonly uses traditional casting islands for casing production. However, existing technologies have the following significant limitations: Casting processes are complex and lengthy. Traditional casting often employs solid mold casting or precision casting. These processes require the pre-fabrication of complex metal molds and involve multiple preparatory steps such as core making, mold assembly, and core placement. This results in a long casting process, cumbersome procedures, high skill requirements for operators, and difficulty in ensuring product consistency and internal quality.

[0003] Traditional casting islands are highly integrated, making changeovers and mold changes difficult: Existing casting islands are typically designed as integrated, fixed production lines. When producing magnetic levitation vacuum pump housings of different specifications or models, due to the high degree of equipment integration and fixed tooling fixtures, a significant amount of manpower must be invested in partially disassembling, reassembling, and debugging the casting island. This process is not only extremely time-consuming and severely reduces production efficiency, but repeated disassembly and reassembly can also easily lead to decreased equipment precision and increased maintenance costs.

[0004] Poor mold adaptability and insufficient flexibility: The central station and mold system of traditional casting islands are often designed specifically for a particular product. Faced with the production needs of multiple varieties and small batches, they cannot respond quickly. Each product change often requires redesigning and manufacturing the entire mold set, and even modifying core equipment, lacking the ability to flexibly adapt to changes in product shape and specifications.

[0005] To address the aforementioned issues, lost foam casting technology has gained attention in recent years. This technology uses a vaporizable foam model that perfectly matches the shape of the casting as the lost foam. During pouring, the model vaporizes and disappears upon contact with the high-temperature molten metal, directly forming the casting. Compared to traditional processes, lost foam casting eliminates the need for mold removal, parting lines, and core making, significantly simplifying the casting process and reducing casting difficulty. It is particularly suitable for complex-shaped shell parts. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention discloses an intelligent casting island that can both utilize the simplified process of lost foam casting and overcome the difficulties of traditional integrated casting islands and mold changeover. The technical solution adopted by this invention is: an intelligent casting island for a magnetic levitation vacuum pump housing, comprising a casting mechanism for casting processing, wherein the casting mechanism is provided with multiple mold mechanisms and a demolding mechanism for demolding. The casting mechanism includes an intermediate frame, on which a rotating disk is rotatably mounted.

[0007] Furthermore, the casting mechanism also includes a sand-shooting machine and a casting machine located next to the intermediate frame. The sand-shooting machine is equipped with a forward sand pipe and a rear sand pipe, and the casting machine is equipped with a casting channel. A turntable gear is fixedly installed on the turntable, and multiple side guide wheels are rotatably installed on the intermediate frame. The turntable and the side guide wheels are in contact. A turntable motor is fixedly installed on the intermediate frame, and a motor gear is fixedly installed on the motor shaft of the turntable motor. The motor gear meshes with the turntable gear.

[0008] Furthermore, the casting mechanism also includes a robotic arm disposed next to the intermediate frame. A fixed plate is fixedly installed at the end of the robotic arm, a clamping electric cylinder is fixedly installed on the fixed plate, a movable plate is fixedly installed on the output end of the clamping electric cylinder, a gripper is rotatably installed on the fixed plate, an inner clamping rod is rotatably installed on the gripper, and the inner clamping rod is rotatably installed with the movable plate.

[0009] Furthermore, the casting mechanism also includes a pressure frame fixedly installed on the intermediate frame, a pressure cylinder fixedly installed on the pressure frame, and a pressure block fixedly installed on the output end of the pressure cylinder.

[0010] Furthermore, the casting mechanism also includes an ejector frame fixedly installed on the intermediate frame, an ejector electric cylinder fixedly installed on the ejector frame, and an ejector block fixedly installed on the output end of the ejector electric cylinder.

[0011] The turntable motor drives the motor gears to rotate, which in turn drive the turntable gears and the turntable itself to rotate, thereby rotating the mold mechanism on the turntable. The turntable motor rotates the turntable 60 degrees each time, pauses for a short period, and then rotates another 60 degrees, repeating this process. In operation, the mold mechanism first reaches the bottom of the infeed sand pipe next to the sand-shooting machine. The sand-shooting machine then delivers some molding sand into the lifting frame through the infeed sand pipe, covering the bottom surface of the lifting frame with a layer of molding sand. Subsequently, the turntable rotates 60 degrees, bringing the mold mechanism to the robotic arm, which then clamps it. The lost foam of the magnetic levitation vacuum pump is placed into the lifting frame. Then, the clamping electric cylinder extends, driving the movable plate to move outward. It drives the gripper to open through the inner clamping rod, so that the gripper no longer holds the lost foam of the magnetic levitation vacuum pump. Then, the robot arm leaves the mold mechanism. Then, the sand shooting machine delivers molding sand into the lifting frame through the rear sand inlet pipe. The molding sand covers the inside of the lifting frame and the lost foam of the magnetic levitation vacuum pump. At the same time, the mold mechanism drives the lifting frame to shake, so that the molding sand is evenly covered in the lifting frame. Meanwhile, the gate end of the lost foam of the magnetic levitation vacuum pump extends out of the molding sand surface.

[0012] Then, the rotating disc drives the mold mechanism to rotate 60 degrees, so that the mold mechanism reaches below the lower pressure frame. The lower pressure electric cylinder extends, driving the lower pressure block to descend. The lower pressure block compacts the molding sand in the rotating disc gear. Then, the rotating disc drives the mold mechanism to rotate 60 degrees, so that the mold mechanism reaches the casting machine. The casting machine pours molten metal into the gate of the magnetic levitation vacuum pump lost foam through the casting channel. Then, the molten metal melts the magnetic levitation vacuum pump lost foam, completing the casting. Then, the rotating disc drives the mold mechanism to rotate 60 degrees, so that the mold mechanism reaches the lifting frame.

[0013] Furthermore, the mold mechanism includes a movable box fixedly mounted on a rotating disk, a vibrating sleeve slidably mounted on the movable box, a vibrating spring provided between the vibrating sleeve and the movable box, a placement frame fixedly mounted on the vibrating sleeve, and a discharge slope fixedly mounted on the placement frame.

[0014] Furthermore, the mold mechanism also includes side sealing plates fixedly installed on both sides of the placement frame, fixed guide pillars fixedly installed on the placement frame, and lifting frames slidably installed on the fixed guide pillars.

[0015] Furthermore, the mold mechanism also includes a lifting column that is slidably installed inside the vibrating sleeve, a lifting plate that is fixedly installed below the lifting column, the lifting column and the lifting frame that are fixedly installed, and front and rear sealing plates that are fixedly installed on the lifting frame.

[0016] Furthermore, the mold mechanism also includes an inner connecting frame fixedly installed inside the movable box. A vibrating motor is fixedly installed on the inner connecting frame. A motor bevel gear is fixedly installed on the motor shaft of the vibrating motor. A horizontal shaft is rotatably installed on the inner connecting frame. A side bevel gear is fixedly installed on the horizontal shaft. The side bevel gear meshes with the motor bevel gear. A vibrating block is eccentrically fixedly installed on the horizontal shaft. The vibrating block contacts the placement frame.

[0017] In normal conditions, the side sealing plate, front and rear sealing plates, and lifting frame are in a closed state, and the lost foam and molding sand of the magnetic levitation vacuum pump are located inside during casting.

[0018] When shaking is required, the shaking motor drives the motor bevel gear to rotate. The motor bevel gear drives the side bevel gear, the horizontal shaft, and the shaking block to rotate. The rotation of the shaking block causes the placement frame and the shaking sleeve to rise along the movable box. At this time, the shaking spring located between the placement frame and the movable box is compressed. Then, when the small radius section of the shaking block contacts the placement frame, the shaking spring between the placement frame and the movable box rebounds. This process is repeated to realize the up and down shaking of the placement frame, thereby shaking the molding sand in the lifting frame, the side sealing plate, and the front and rear sealing plates.

[0019] Furthermore, the demolding mechanism includes a bottom support located below the intermediate frame, a lifting electric cylinder is fixedly installed on the bottom support, a lifting frame is fixedly installed on the output end of the lifting electric cylinder, a docking groove is provided on the lifting frame, and a vertical guide column is fixedly installed below the lifting frame, with the vertical guide column slidably installed with the bottom support.

[0020] Initially, the lifting cylinder is in the retracted state. When the mold mechanism moves above the bottom support, the lifting plate enters the docking groove. Then, the lifting cylinder extends, causing the lifting frame and guide column to rise. At this time, the lifting plate, through the lifting column, drives the lifting frame and front and rear sealing plates to rise, allowing the molding sand on the placement rack and the cast magnetic levitation vacuum pump to dissipate heat. Then, the lifting cylinder retracts, causing the lifting frame and lifting plate to descend. Subsequently, the rotating disk and the mold mechanism rotate 60 degrees, at which point the lifting plate slides within the docking groove. When the mold mechanism reaches the ejection rack, the lifting cylinder extends, causing the lifting frame and... As the guide column rises, the lifting plate, through the lifting column, drives the lifting frame and the front and rear sealing plates to rise. Then, the ejector cylinder moves the ejector block outward, pushing the molding sand and the completed magnetic levitation vacuum pump in the mold mechanism next to the ejector frame onto the discharge slope. The molding sand and the magnetic levitation vacuum pump slide out along the discharge slope. Then, the lifting cylinder retracts, causing the lifting plate to descend, which closes the side sealing plate, the front and rear sealing plates, and the lifting frame again. Then, the casting channel rotates the mold mechanism another 60 degrees for the next processing. All six mold mechanisms follow the above process to achieve continuous processing at six stations.

[0021] The beneficial effects of this invention compared with the prior art are: (1) This invention adopts the lost foam casting process, which eliminates the need for complex processes such as mold making, parting surface design, core making and box assembly in traditional casting. By directly burying the gasifiable foam model into molding sand and pouring molten metal, the model gasifies and forms a casting in situ, which fundamentally reduces the complexity of the casting process and the skill requirements of the operators. At the same time, by using the automated process of sand shooting, shaking, compaction and pouring, continuous operation from model placement to casting formation is realized, which simplifies the production process and improves the process stability and casting quality; (2) This invention adopts a modular structure composed of multiple independent functional units. Each module can be disassembled, reassembled or maintained at any time according to production needs. When changing product models or molds, it is not necessary to disassemble and reassemble the whole machine with a lot of manpower like traditional equipment. Only the corresponding lost foam model needs to be replaced, which shortens the downtime of production switching, reduces maintenance costs, and improves the overall utilization rate of equipment; (3) The design of the central turntable and mold mechanism of the present invention is universal. The turntable is only responsible for positioning and transporting the mold mechanism, while the lifting frame, side sealing plate and other components in the mold mechanism are only used to accommodate molding sand and lost foam model. Since the final shape of the casting is completely determined by the lost foam model, rather than by the inner cavity shape of the metal mold, only different specifications of lost foam models are needed to continuously produce magnetic levitation vacuum pump shells of different shapes and sizes on the same casting island.

Detailed Implementation

[0031] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0032] Example: Reference Figures 1-8 A smart casting island for the housing of a magnetic levitation vacuum pump includes a casting mechanism for casting, which is equipped with multiple mold mechanisms and a demolding mechanism for demolding. The casting mechanism includes an intermediate frame 101, on which a rotating disk 107 is rotatably mounted.

[0033] like Figures 2-4 As shown, the casting mechanism also includes a sand-shooting machine 102 and a casting machine 105 located next to the intermediate frame 101. The sand-shooting machine 102 is equipped with a forward sand pipe 103 and a rear sand pipe 104. The casting machine 105 is equipped with a casting channel 106. A turntable gear 108 is fixedly installed on the turntable 107. Multiple side guide wheels 111 are rotatably installed on the intermediate frame 101. The turntable 107 is in contact with the side guide wheels 111. A turntable motor 109 is fixedly installed on the intermediate frame 101. A motor gear 110 is fixedly installed on the motor shaft of the turntable motor 109. The motor gear 110 meshes with the turntable gear 108.

[0034] like Figures 2-4As shown, the casting mechanism also includes a robot arm 112 located next to the intermediate frame 101. A fixed plate 113 is fixedly installed at the end of the robot arm 112. A clamping electric cylinder 114 is fixedly installed on the fixed plate 113. A movable plate 115 is fixedly installed on the output end of the clamping electric cylinder 114. A gripper 116 is rotatably installed on the fixed plate 113. An inner clamping rod 117 is rotatably installed on the gripper 116. The inner clamping rod 117 is rotatably installed with the movable plate 115.

[0035] like Figures 2-4 As shown, the casting mechanism also includes a pressure frame 118 fixedly installed on the intermediate frame 101, a pressure cylinder 119 fixedly installed on the pressure frame 118, and a pressure block 120 fixedly installed on the output end of the pressure cylinder 119.

[0036] like Figures 2-4 As shown, the casting mechanism also includes an ejector frame 121 fixedly installed on the intermediate frame 101, an ejector cylinder 122 fixedly installed on the ejector frame 121, and an ejector block 123 fixedly installed on the output end of the ejector cylinder 122.

[0037] The turntable motor 109 drives the motor gear 110 to rotate, which in turn drives the turntable gear 108 and the turntable 107 to rotate, thereby causing the mold mechanism on the turntable 107 to rotate. The turntable motor 109 rotates the turntable 107 60 degrees each time, stops for a period of time, and then rotates it 60 degrees again, repeating this process. In operation, the mold mechanism first reaches the infeed sand pipe 103 next to the sand-shooting machine 102. The sand-shooting machine 102 then transports some molding sand into the lifting frame 208 through the infeed sand pipe 103, covering the bottom surface of the lifting frame 208 with a layer of molding sand. Then, the turntable 107 rotates 60 degrees, bringing the mold mechanism to the side of the robot arm 112. The robot arm then... 112 places the lost foam of the magnetic levitation vacuum pump into the lifting frame 208. Then, the clamping electric cylinder 114 extends, driving the movable plate 115 to move outward. It drives the gripper 116 to open through the inner clamping rod 117, so that the gripper 116 no longer clamps the lost foam of the magnetic levitation vacuum pump. Then, the robot arm 112 leaves the mold mechanism. Then, the sand shooting machine 102 delivers molding sand into the lifting frame 208 through the rear sand inlet pipe 104. The molding sand covers the inside of the lifting frame 208 and the lost foam of the magnetic levitation vacuum pump. At the same time, the mold mechanism drives the lifting frame 208 to vibrate, so that the molding sand is evenly covered inside the lifting frame 208. Meanwhile, the gate end of the lost foam of the magnetic levitation vacuum pump extends out of the molding sand surface.

[0038] Subsequently, the rotating disk 107 drives the mold mechanism to rotate 60 degrees, so that the mold mechanism reaches below the lower pressure frame 118. The lower pressure electric cylinder 119 extends, driving the lower pressure block 120 to descend. The lower pressure block 120 compacts the molding sand in the rotating disk gear 108. Then, the rotating disk 107 drives the mold mechanism to rotate 60 degrees, so that the mold mechanism reaches the side of the casting machine 105. The casting machine 105 pours the molten metal into the gate of the magnetic levitation vacuum pump lost foam through the casting channel 106. Then, the molten metal melts the magnetic levitation vacuum pump lost foam, completing the casting. Then, the rotating disk 107 drives the mold mechanism to rotate 60 degrees, so that the mold mechanism reaches the lifting frame 303.

[0039] like Figures 5-7 As shown, the mold mechanism includes a movable box 201 fixedly installed on a rotating disk 107, a vibrating sleeve 202 slidably installed on the movable box 201, a vibrating spring 203 provided between the vibrating sleeve 202 and the movable box 201, a placement frame 207 fixedly installed on the vibrating sleeve 202, and a discharge slope 206 fixedly installed on the placement frame 207.

[0040] like Figures 5-7 As shown, the mold mechanism also includes side sealing plates 209 fixedly installed on both sides of the placement frame 207, fixed guide pillars 211 fixedly installed on the placement frame 207, and lifting frames 208 slidably installed on the fixed guide pillars 211.

[0041] like Figures 5-7 As shown, the mold mechanism also includes a lifting column 204 that is slidably installed in the vibrating sleeve 202. A lifting plate 205 is fixedly installed below the lifting column 204. The lifting column 204 is fixedly installed with the lifting frame 208. Front and rear sealing plates 210 are fixedly installed on the lifting frame 208.

[0042] like Figures 5-7 As shown, the mold mechanism also includes an inner connecting frame 214 fixedly installed in the movable box 201. A vibrating motor 212 is fixedly installed on the inner connecting frame 214. A motor bevel gear 213 is fixedly installed on the motor shaft of the vibrating motor 212. A horizontal shaft 215 is rotatably installed on the inner connecting frame 214. A side bevel gear 216 is fixedly installed on the horizontal shaft 215. The side bevel gear 216 meshes with the motor bevel gear 213. A vibrating block 217 is eccentrically fixedly installed on the horizontal shaft 215. The vibrating block 217 contacts the placement frame 207.

[0043] In normal conditions, the side sealing plate 209, the front and rear sealing plates 210, and the lifting frame 208 are in a closed state, and the lost foam and molding sand of the magnetic levitation vacuum pump are located within them during casting.

[0044] When shaking is required, the shaking motor 212 drives the motor bevel gear 213 to rotate. The motor bevel gear 213 drives the side bevel gear 216, the horizontal shaft 215 and the shaking block 217 to rotate. The rotation of the shaking block 217 drives the placement frame 207 and the shaking sleeve 202 to rise along the movable box 201. At this time, the shaking spring 203 located between the placement frame 207 and the movable box 201 is compressed. Then, when the small radius section of the shaking block 217 contacts the placement frame 207, the shaking spring 203 between the placement frame 207 and the movable box 201 rebounds. This process is repeated to realize the up and down shaking of the placement frame 207, thereby shaking the molding sand in the lifting frame 208, the side sealing plate 209 and the front and rear sealing plates 210.

[0045] like Figure 8 As shown, the demolding mechanism includes a bottom support 301 located below the intermediate frame 101. A lifting cylinder 302 is fixedly installed on the bottom support 301. A lifting frame 303 is fixedly installed on the output end of the lifting cylinder 302. A docking groove 304 is provided on the lifting frame 303. A vertical guide column 305 is fixedly installed below the lifting frame 303. The vertical guide column 305 is slidably installed with the bottom support 301.

[0046] Initially, the lifting cylinder 302 is in the retracted state. When the mold mechanism moves above the bottom support 301, the lifting plate 205 enters the docking groove 304. Then, the lifting cylinder 302 extends, driving the lifting frame 303 and the vertical guide column 305 to rise. At this time, the lifting plate 205 drives the lifting frame 208 and the front and rear sealing plates 210 to rise through the lifting column 204. This allows the molding sand on the placement frame 207 and the completed magnetic levitation vacuum pump to dissipate heat. Then, the lifting cylinder 302 retracts, driving the lifting frame 303 and the lifting plate 205 to fall. Then, the rotating disk 107 and the mold mechanism rotate 60 degrees. At this time, the lifting plate 205 slides in the docking groove 304. When the mold mechanism reaches the ejection frame 121, the lifting cylinder 302 extends, driving the lifting frame 303 and the vertical guide column 305 to fall. The lowering frame 303 and the guide column 305 rise. At this time, the lifting plate 205 drives the lifting frame 208 and the front and rear sealing plates 210 to rise through the lifting column 204. Then, the push-out electric cylinder 122 drives the push-out block 123 to move outward. The push-out block 123 pushes the molding sand and the completed magnetic levitation vacuum pump in the mold mechanism next to the push-out frame 121 onto the discharge slope 206. The molding sand and the magnetic levitation vacuum pump slide out along the discharge slope 206. Then, the lifting electric cylinder 302 retracts, causing the lifting plate 205 to fall, so that the side sealing plate 209, the front and rear sealing plates 210 and the lifting frame 208 are closed again. Then, the casting channel 106 rotates the mold mechanism another 60 degrees for the next processing. All six mold mechanisms are processed according to the above process to achieve continuous processing of six stations.

[0047] Working principle: In normal operation, the side sealing plate 209, front and rear sealing plates 210, and lifting frame 208 are in a closed state. The turntable motor 109 drives the motor gear 110 to rotate, which in turn drives the turntable gear 108 and the turntable 107 to rotate, thereby driving the mold mechanism on the turntable 107 to rotate. The turntable motor 109 drives the turntable 107 to rotate 60 degrees each time, stops rotating for a period of time, and then continues to rotate 60 degrees, repeating this process. In use, the mold mechanism first reaches the infeed sand pipe 1 next to the sand shooting machine 102. Below 03, the sand-shooting machine 102 delivers a portion of molding sand into the lifting frame 208 through the forward sand pipe 103, covering the bottom surface of the lifting frame 208 with a layer of molding sand. Then, the rotating disk 107 rotates 60 degrees, bringing the mold mechanism to the side of the robot arm 112. The robot arm 112 then places the lost foam of the magnetic levitation vacuum pump into the lifting frame 208. Subsequently, the clamping electric cylinder 114 extends, driving the movable disk 115 outward. This movement, via the inner clamping rod 117, causes the grippers 116 to open, releasing the grippers from their clamping position. The magnetic levitation vacuum pump performs a lost foam casting process. Then, the robotic arm 112 leaves the mold mechanism. Next, the sand-shooting machine 102 delivers molding sand through the rear sand inlet pipe 104 into the lifting frame 208. The molding sand covers the lifting frame 208 and the lost foam casting process of the magnetic levitation vacuum pump. Simultaneously, the vibrating motor 212 drives the motor bevel gear 213 to rotate. The motor bevel gear 213 drives the side bevel gear 216, the horizontal shaft 215, and the vibrating block 217 to rotate. The rotation of the vibrating block 217 causes the placement frame 207 and the vibrating sleeve 202 to rise along the movable box 201. When the shaking spring 203 located between the placement frame 207 and the movable box 201 is compressed, and then when the small radius section of the shaking block 217 contacts the placement frame 207, the shaking spring 203 between the placement frame 207 and the movable box 201 rebounds. This process is repeated to make the placement frame 207 shake up and down, thereby shaking the molding sand in the lifting frame 208, the side sealing plate 209 and the front and rear sealing plates 210, so that the molding sand is evenly covered in the lifting frame 208. At the same time, the gate end of the magnetic levitation vacuum pump disappearing foam extends out of the molding sand surface.

[0048] Subsequently, the rotating disk 107 drives the mold mechanism to rotate 60 degrees, so that the mold mechanism reaches below the lower pressure frame 118. The lower pressure electric cylinder 119 extends, driving the lower pressure block 120 to descend. The lower pressure block 120 compacts the molding sand in the rotating disk gear 108. Then, the rotating disk 107 drives the mold mechanism to rotate 60 degrees, so that the mold mechanism reaches the side of the casting machine 105. The casting machine 105 pours the molten metal into the gate of the magnetic levitation vacuum pump lost foam through the casting channel 106. Then, the molten metal melts the magnetic levitation vacuum pump lost foam, completing the casting. Then, the rotating disk 107 drives the mold mechanism to rotate 60 degrees, so that the mold mechanism reaches the lifting frame 303.

[0049] Initially, the lifting cylinder 302 is in the retracted state. When the mold mechanism moves above the bottom support 301, the lifting plate 205 enters the docking groove 304. Then, the lifting cylinder 302 extends, driving the lifting frame 303 and the vertical guide column 305 to rise. At this time, the lifting plate 205 drives the lifting frame 208 and the front and rear sealing plates 210 to rise through the lifting column 204. This allows the molding sand on the placement frame 207 and the completed magnetic levitation vacuum pump to dissipate heat. Then, the lifting cylinder 302 retracts, driving the lifting frame 303 and the lifting plate 205 to fall. Then, the rotating disk 107 and the mold mechanism rotate 60 degrees. At this time, the lifting plate 205 slides in the docking groove 304. When the mold mechanism reaches the ejection frame 121, the lifting cylinder 302 extends, driving the lifting frame 303 and the vertical guide column 305 to fall. The lowering frame 303 and the guide column 305 rise. At this time, the lifting plate 205 drives the lifting frame 208 and the front and rear sealing plates 210 to rise through the lifting column 204. Then, the push-out electric cylinder 122 drives the push-out block 123 to move outward. The push-out block 123 pushes the molding sand and the completed magnetic levitation vacuum pump in the mold mechanism next to the push-out frame 121 onto the discharge slope 206. The molding sand and the magnetic levitation vacuum pump slide out along the discharge slope 206. Then, the lifting electric cylinder 302 retracts, causing the lifting plate 205 to fall, so that the side sealing plate 209, the front and rear sealing plates 210 and the lifting frame 208 are closed again. Then, the casting channel 106 rotates the mold mechanism another 60 degrees for the next processing. All six mold mechanisms are processed according to the above process to achieve continuous processing of six stations.
