[0002] Metal products are a general term for all metal products including tools, containers, supplies, etc. They are widely used in industry, agriculture and daily life. Centrifugal casting is a very good processing method for coaxial and concentric products. Centrifugal casting uses high-speed rotation of the mold to make the liquid metal fit evenly and tightly inside the mold, so that the inner and outer wall thickness of the product is uniform, reducing the occurrence of pinhole shrinkage, and facilitating cooling and molding. The loading and unloading process of the centrifugal casting device for metal products in the prior art is too cumbersome, and it is impossible to achieve fully automatic centrifugal casting.

[0006] Furthermore, an upper mold is placed on two of the four lower plates, teeth are arranged below the upper mold, the teeth below the upper mold cooperate with the locking teeth on the inner mold, a number of docking buckles are arranged on the upper mold, the number of the docking buckles corresponds to the number of insertion rods, a casting gate is arranged on the top of the upper mold, and an inwardly opened switch plate is arranged in the casting gate, and when the metal liquid is not introduced, the switch plate remains closed under the action of the spring.

[0007] Furthermore, a lower electric cylinder is fixedly mounted on the base, a movable rack is fixedly mounted on the output end of the lower electric cylinder, the movable rack is meshed with the center gear, a gear column is rotatably mounted on the base, an upper gear and a lower gear are fixedly mounted on the gear column, the upper gear is meshed with the center gear, and a bottom transmission belt is wrapped around the lower gear and the lower gear.

[0008] Furthermore, the lifting module includes a rotating arc plate rotatably mounted on the base, a rotating column is fixedly mounted on the rotating arc plate, a rotating rod is rotatably mounted on the rotating column, the rotating rod and the movable rack are rotatably mounted, a lifting plate is fixedly mounted on the rotating arc plate, the upper surface of the lifting plate is a slope, and a lifting block is slidably mounted on the base.

[0009] Furthermore, the toggle module includes a lower motor fixedly mounted on the base, a motor gear fixedly mounted on the motor shaft of the lower motor, a rod pulling column rotatably mounted on the base, a rod pulling frame fixedly mounted on the rod pulling column, four open slide grooves are provided on the rod pulling frame, and a transmission belt is wrapped around the rod pulling column and the motor gear.

[0010] The device is provided with four workstations, namely, the mold placing workstation, the casting workstation, the mold opening workstation and the discharging workstation. The lower motor drives the motor gear to rotate, and drives the rod pulling column and the rod pulling frame to rotate ninety degrees through the transmission belt. When the rod pulling frame rotates, the contact between the open slide groove and the rotating base frame drives the rotating frame to rotate ninety degrees counterclockwise. When the lower motor does not rotate, the rotating base frame is located in the open slide groove of the rod pulling frame. At this time, the rotating frame cannot rotate, that is, the rotating frame will be driven to rotate only when the rod pulling frame rotates, and the rotating frame rotates ninety degrees counterclockwise each time. The workstation on the rotating motor side is the casting workstation, and the workstation on the vertical electric cylinder side is the discharging workstation. After the rotating frame rotates ninety degrees counterclockwise, the rotating base frame originally at the casting workstation reaches the mold opening workstation, and the rotating base frame originally at the discharging workstation reaches the mold placing workstation.

[0011] Lowering the arc rod causes the pick-and-place column to descend, which in turn drives the pick-and-place frame and the insertion rod to descend. The upper sleeve, the upper inner sleeve, and the lower inner sleeve descend, compressing the strong spring. The insertion rod reaches the outside of the upper mold at the mold-opening station. At this time, the insertion rod is not inserted into the docking buckle. At this moment, the friction wheel drives the self-rotating gear to rotate, which in turn drives the rotating bottom frame, the lower disk, and the upper mold to rotate, causing the insertion rod to be inserted into the docking buckle. At this time, the rotating bottom frame at the casting station is not lifted by the lifting plate, and the self-rotating gear at the casting station does not mesh with the docking gear, so the centrifugal casting action does not occur. Subsequently, the arc rod is raised, and the pick-and-place column and the pick-and-place frame rise under the reset of the strong spring. The upper mold at the mold-opening station is lifted by the insertion rod, exposing the cast metal product. Subsequently, the lower electric cylinder extends to drive the movable rack to move, which in turn drives the central gear and the pick-and-place frame to rotate counterclockwise by 180 degrees. At this time, the pick-and-place frame and the insertion rod move the upper mold to above the inner mold at the mold-placement station. Subsequently, the arc rod descends, placing the upper mold on the lower disk at the mold-placement station. The upper mold and the lower disk are completed in cooperation. Subsequently, the friction wheel drives the self-rotating gear to reverse, causing the insertion rod to disengage from the docking buckle. Subsequently, the arc rod rises, causing the pick-and-place frame to rise. Subsequently, the lower electric cylinder contracts and resets, completing the transfer of the upper mold on the lower disk at the mold-opening station to the lower disk at the mold-placement station, facilitating the removal of the cast metal product by the discharging station.

[0012] During the process of the lower electric cylinder driving the movable rack to move, it will drive the rotating column and the rotating arc plate to rotate through the rotating rod, thereby driving the lifting plate to move. The lifting plate drives the lifting block to rise through the slope on the upper surface. The rising of the lifting block drives the rotating bottom frame and the self-rotating gear at the casting station to rise. When the lower electric cylinder extends to the longest, the lifting plate completely lifts the lifting block, and the self-rotating gear at the casting station meshes with the docking gear. The molten metal is poured into the upper mold through the pouring port of the upper mold. At this time, the friction wheel drives the self-rotating gear and the lower disk to rotate for centrifugal casting. After casting is completed, during the casting process, the arc rod does not descend. During the contraction of the lower electric cylinder, as the rotating arc plate rotates in the reverse direction, the self-rotating gear and the rotating bottom frame descend, and the self-rotating gear at the casting station disengages from the docking gear. When centrifugal casting is completed and the upper mold at the mold-opening station is moved to the mold-placement station, the extraction rod frame rotates 90 degrees, driving the rotating frame to rotate counterclockwise by 90 degrees, so that the rotating bottom frame originally at the mold-placement station reaches the casting station, the rotating bottom frame originally at the casting station reaches the mold-opening station, the rotating bottom frame originally at the mold-opening station reaches the discharging station, and the rotating bottom frame originally at the discharging station reaches the mold-placement station.

[0013] Further, the rotation mechanism includes a rotation gear fixedly installed on the motor shaft of the rotation motor. An external gear column is rotatably installed on the base. A driving gear, an intermediate gear, and a docking gear are fixedly installed on the external gear column. Two side gears are rotatably installed on the base. A top gear is fixedly installed on the side gears. The driving gear meshes with the rotation gear. The side gears mesh with the intermediate gear. A transfer drive wheel is rotatably installed on the base. A side frame is fixedly installed on the base. A friction wheel is rotatably installed on the side frame. A side drive belt is wound around the friction wheel, the transfer drive wheel, and the top gear.

[0014] When the rotation motor starts, it drives the rotation gear to rotate, thereby driving the driving gear, the external gear column, the intermediate gear, and the docking gear to rotate, thereby driving the side gears and the top gear to rotate. The friction wheel is driven to rotate through the side drive belt. The two friction wheels respectively mesh with the self-rotation gears at the mold placing station and the mold opening station. After the rotation base frame at the casting station is lifted by the lifting block, the self-rotation gear at the casting station meshes with the docking gear.

[0015] Further, the taking-out mechanism includes an inner rotating rod rotatably installed on the base. The inner rotating rod is fixedly installed with a lower gear. An outer sliding rod is slidably installed on the inner rotating rod. An inner spring is arranged between the outer sliding rod and the inner rotating rod. A chute turntable is fixedly installed on the outer sliding rod. An arc groove is arranged on the chute turntable. The output end of the vertical electric cylinder slides in the arc groove of the chute turntable. A pressing arc rod is fixedly installed on the chute turntable. The lower surface of the pressing arc rod contacts the picking and placing frame.

[0016] Further, a picking rack is fixedly installed below the pressing arc rod. A plurality of picking rods are slidably installed on the picking rack. Picking pieces are fixedly installed on the picking rods. The picking pieces are provided with patterns for increasing friction. A picking spring is arranged between the picking pieces and the picking rack. The picking pieces are provided with slopes.

[0017] The contraction of the vertical electric cylinder drives the chute turntable to descend, the inner spring is compressed, and the descent of the chute turntable drives the lower pressing arc rod and the material taking rack to descend. When the material taking piece contacts the metal product on the lower plate of the discharging station, the metal product will push the material taking piece and the material taking rod outwards through the slope of the material taking piece, and the material taking spring is compressed. Subsequently, the grooved part of the material taking piece reaches the outside of the metal product. At this time, an inward clamping force is provided by the material taking spring. Then, the vertical electric cylinder rises to drive the lower pressing arc rod and the material taking rack to rise, and the metal product on the lower plate of the discharging station is lifted by the material taking piece; when the picking and placing rack rotates counterclockwise by 180 degrees, the central gear drives the upper gear, the gear column and the lower gear to rotate, and drives the lower gear and the inner rotating rod to rotate through the bottom transmission belt, thereby driving the outer sliding rod, the chute turntable, the lower pressing arc rod and the material taking rack to rotate clockwise by 180 degrees, so that the material taking piece takes the metal product away above the discharging station. At this time, the metal product clamped by the material taking piece is taken out. When the picking and placing rack rotates counterclockwise by 180 degrees, the lower pressing arc rod rotates clockwise by 180 degrees. The lower pressing arc rod is always above the picking and placing rack, so that when the lower pressing arc rod descends, it drives the picking and placing rack to descend synchronously, and when the lower pressing arc rod rises, the picking and placing rack rises synchronously under the reset of the strong spring.

[0018] That is, first, the lower pressing arc rod descends, driving the picking and placing rack to descend, so that the insertion rod reaches beside the upper mold of the mold opening station, and through the rotation of the upper mold, the insertion rod is inserted into the docking buckle. At the same time, the material taking piece clamps the metal product at the discharging station. Subsequently, the lower pressing arc rod and the picking and placing rack rise, lifting the upper mold of the mold opening station, and the material taking piece lifts the metal product. Then, the lower electric cylinder extends to the longest, the picking and placing rack rotates counterclockwise by 180 degrees, the lower pressing arc rod rotates clockwise by 180 degrees, and the jacking plate jacks up the rotating bottom frame of the casting station. At this time, the docking gear drives the lower plate of the casting station to rotate for centrifugal casting, and at the same time, the metal product clamped by the material taking piece is taken out. Subsequently, the picking and placing rack descends and rotates in cooperation with the rotating bottom frame of the mold placing station to place the upper mold on the lower plate of the mold placing station. At this time, the operation of placing the upper mold at the mold placing station is completed, the centrifugal casting operation at the casting station is completed, the operation of taking away the upper mold at the mold opening station is completed, and the operation of taking away the metal product at the discharging station is completed. Then, the rotating frame rotates counterclockwise by 90 degrees to transfer all stations to the next station and proceed in sequence.

[0019] Compared with the prior art, the present invention has the following beneficial effects: (1) the lower pressing arc rod and the pick-up rack provided in the present invention are lowered, so that the insertion rod reaches the upper mold of the mold opening station, and the upper mold is rotated to insert the insertion rod into the butt buckle, and the material sheet is taken to clamp the metal product at the discharge station, then the lower pressing arc rod and the pick-up rack are raised to lift the upper mold of the mold opening station, the material sheet is taken to lift the metal product, then the lower electric cylinder is extended to the longest, the pick-up rack rotates 180 degrees counterclockwise, and the lower pressing arc rod rotates 180 degrees clockwise, so as to realize the fully automatic upper mold transfer and forming. The product can be taken out with a high degree of automation; (2) when the lower electric cylinder provided in the present invention is extended to the maximum, the lifting plate lifts up the rotating base frame of the casting station at the same time, and the docking gear drives the lower plate of the casting station to rotate for centrifugal casting, which has good continuity; (3) the toggle module provided in the present invention drives the rotating frame to rotate 90 degrees each time, so that the rotating base frame originally at the mold release station reaches the casting station, the rotating base frame originally at the casting station reaches the mold opening station, the rotating base frame originally at the mold opening station reaches the material discharging station, and the rotating base frame originally at the material discharging station reaches the mold release station.

[0035] like Figures 2 - 6 As shown, an upper mold 116 is placed on two of the four lower plates 114, and teeth are arranged below the upper mold 116. The teeth below the upper mold 116 cooperate with the locking teeth on the inner mold 115. A plurality of docking buckles 117 are arranged on the upper mold 116, and the number of the docking buckles 117 corresponds to the number of the insertion rods 110. A casting port is arranged on the top of the upper mold 116. When the metal liquid is not introduced, the switch plate is kept closed by the action of the spring.

[0036] like Figures 2 - 6 As shown, a lower electric cylinder 118 is fixedly mounted on the base 101, a movable rack 119 is fixedly mounted on the output end of the lower electric cylinder 118, the movable rack 119 is meshed with the center gear 107, a gear column 125 is rotatably mounted on the base 101, an upper gear 126 and a lower gear 127 are fixedly mounted on the gear column 125, the upper gear 126 is meshed with the center gear 107, and a bottom transmission belt 128 is wound around the lower gear 303 and the lower gear 127.

[0037] like Figures 2 - 6 As shown, the lifting module includes a rotating arc plate 122 rotatably mounted on the base 101, a rotating column 121 is fixedly mounted on the rotating arc plate 122, a rotating rod 120 is rotatably mounted on the rotating column 121, the rotating rod 120 is rotatably mounted with the movable rack 119, a lifting plate 123 is fixedly mounted on the rotating arc plate 122, the upper surface of the lifting plate 123 is a slope, and a lifting block 124 is slidably mounted on the base 101.

[0038] As Figures 2 - 6 shown, the toggling module includes a lower motor 129 fixedly installed on the base 101. A motor gear 130 is fixedly installed on the motor shaft of the lower motor 129. A toggle rod column 132 is rotatably installed on the base 101. A toggle rod frame 133 is fixedly installed on the toggle rod column 132. Four open chutes are provided on the toggle rod frame 133. A transmission belt 131 is wound around the toggle rod column 132 and the motor gear 130.

[0039] The device is provided with four working stations, namely the mold placing station, the casting station, the mold opening station and the discharging station in sequence. The lower motor 129 drives the motor gear 130 to rotate, and drives the toggle rod column 132 and the toggle rod frame 133 to rotate by 90 degrees through the transmission belt 131. When the toggle rod frame 133 rotates, it drives the rotating frame 109 to rotate counterclockwise by 90 degrees through the contact between the open chute and the rotating base 111. When the lower motor 129 does not rotate, the rotating base 111 is located in the open chute of the toggle rod frame 133. At this time, the rotating frame 109 cannot rotate, that is, only when the toggle rod frame 133 rotates will it drive the rotating frame 109 to rotate, and the rotating frame 109 rotates counterclockwise by 90 degrees each time. The working station on the side of the rotating motor 201 is the casting station, and the working station on the side of the vertical electric cylinder 301 is the discharging station. After the rotating frame 109 rotates counterclockwise by 90 degrees, the rotating base 111 originally in the casting station reaches the mold opening station, and the rotating base 111 originally in the discharging station reaches the mold placing station.

[0040] It descends by pressing down the arc rod 307, driving the pick-and-place column 106 to descend, thereby driving the pick-and-place frame 108 and the insertion rod 110 to descend. The upper sleeve 105, the upper inner sleeve 104, and the lower inner sleeve 103 descend, and the strong spring is compressed. The insertion rod 110 reaches the outside of the upper mold 116 at the mold-opening station. At this time, the insertion rod 110 is not inserted into the docking buckle 117. At this time, the friction wheel 212 drives the self-rotating gear 113 to rotate, thereby driving the rotating chassis 111, the lower disk 114, and the upper mold 116 to rotate, so that the insertion rod 110 is inserted into the docking buckle 117. At this time, the rotating chassis 111 at the casting station is not lifted by the lifting plate 123, and the self-rotating gear 113 at the casting station does not mesh with the docking gear 206, and the centrifugal casting action does not occur. Subsequently, the arc rod 307 rises, and the pick-and-place column 106 and the pick-and-place frame 108 rise under the reset of the strong spring. The upper mold 116 at the mold-opening station is lifted by the insertion rod 110, so that the cast metal product is exposed. Subsequently, the lower electric cylinder 118 extends to drive the movable rack 119 to move, thereby driving the central gear 107 and the pick-and-place frame 108 to rotate counterclockwise by 180 degrees. At this time, the pick-and-place frame 108 and the insertion rod 110 move the upper mold 116 to above the inner mold 115 at the mold-placement station. Subsequently, the arc rod 307 descends, and the upper mold 116 is placed on the lower disk 114 at the mold-placement station. The upper mold 116 and the lower disk 114 are completed in cooperation. Subsequently, the friction wheel 212 drives the self-rotating gear 113 to reverse, so that the insertion rod 110 disengages from the docking buckle 117. Subsequently, the arc rod 307 rises, causing the pick-and-place frame 108 to rise. Subsequently, the lower electric cylinder 118 contracts and resets, completing the transfer of the upper mold 116 on the lower disk 114 at the mold-opening station to the lower disk 114 at the mold-placement station, facilitating the removal of the cast metal product by the discharging station.

[0041] During the process of the lower electric cylinder 118 driving the movable rack 119 to move, the rotating rod 120 will drive the rotating column 121 and the rotating arc plate 122 to rotate, thereby driving the lifting plate 123 to move. The lifting plate 123 drives the lifting block 124 to rise through the slope on the upper surface. The rising of the lifting block 124 drives the rotating chassis 111 and the self-rotating gear 113 located at the casting station to rise. When the lower electric cylinder 118 extends to the longest, the lifting plate 123 completely lifts the lifting block 124. The self-rotating gear 113 at the casting station meshes with the docking gear 206, and the molten metal is introduced into the upper mold 116 through the casting port of the upper mold 116. At this time, the friction wheel 212 drives the self-rotating gear 113 and the lower disk 114 to rotate for centrifugal casting. After casting is completed, during the casting process, the pressing arc rod 307 does not descend. During the contraction process of the lower electric cylinder 118, as the rotating arc plate 122 rotates in the reverse direction, the self-rotating gear 113 and the rotating chassis 111 descend, and the self-rotating gear 113 at the casting station disengages from the docking gear 206. When centrifugal casting is completed and the upper mold 116 at the mold opening station is moved to the mold placing station, the pulling rod frame 133 rotates 90 degrees, driving the rotating frame 109 to rotate counterclockwise by 90 degrees, so that the rotating chassis 111 originally at the mold placing station reaches the casting station, the rotating chassis 111 originally at the casting station reaches the mold opening station, the rotating chassis 111 originally at the mold opening station reaches the discharging station, and the rotating chassis 111 originally at the discharging station reaches the mold placing station.

[0042] As Figure 7 、 Figure 8 shown, the rotating mechanism includes a rotating gear 202 fixedly installed on the motor shaft of the rotating motor 201. An external gear column 203 is rotatably installed on the base 101. A driving gear 204, an intermediate gear 205, and a docking gear 206 are fixedly installed on the external gear column 203. Two side gears 207 are rotatably installed on the base 101. A top gear 208 is fixedly installed on the side gear 207. The driving gear 204 meshes with the rotating gear 202, the side gear 207 meshes with the intermediate gear 205. A transfer drive wheel 210 is rotatably installed on the base 101. A side frame 211 is fixedly installed on the base 101. A friction wheel 212 is rotatably installed on the side frame 211. A side drive belt 209 is wound around the friction wheel 212, the transfer drive wheel 210, and the top gear 208.

[0043] When the rotating motor 201 starts, it drives the rotating gear 202 to rotate, thereby driving the driving gear 204, the outer gear column 203, the intermediate gear 205, and the docking gear 206 to rotate, and then driving the side gear 207 and the top gear 208 to rotate. The friction wheels 212 are driven to rotate through the side transmission belt 209. The two friction wheels 212 are respectively engaged with the self-rotating gears 113 at the mold placing station and the mold opening station. After the rotating chassis 111 at the casting station is lifted by the lifting block 124, the self-rotating gear 113 at the casting station is engaged with the docking gear 206.

[0044] As Figure 9 , Figure 10 shown, the taking-out mechanism includes an inner rotating rod 302 rotatably installed on the base 101. The inner rotating rod 302 is fixedly installed with a lower gear 303. An outer sliding rod 304 is slidably installed on the inner rotating rod 302. An inner spring 305 is arranged between the outer sliding rod 304 and the inner rotating rod 302. A chute turntable 306 is fixedly installed on the outer sliding rod 304. An arc chute is arranged on the chute turntable 306. The output end of the vertical electric cylinder 301 slides in the arc chute of the chute turntable 306. A pressing arc rod 307 is fixedly installed on the chute turntable 306. The lower surface of the pressing arc rod 307 contacts the picking and placing frame 108.

[0045] As Figure 9 , Figure 10 shown, a material taking frame 308 is fixedly installed below the pressing arc rod 307. A plurality of material taking rods 310 are slidably installed on the material taking frame 308. A material taking piece 309 is fixedly installed on the material taking rod 310. Threads for increasing friction are arranged on the material taking piece 309. A material taking spring 311 is arranged between the material taking piece 309 and the material taking frame 308. A slope is arranged on the material taking piece 309.

[0046] The contraction of the vertical electric cylinder 301 drives the chute turntable 306 to descend, compressing the inner spring 305. The descent of the chute turntable 306 drives the downward pressure arc rod 307 and the material taking frame 308 to descend. When the material taking piece 309 contacts the metal product on the lower plate 114 at the discharging station, the metal product will push the material taking piece 309 and the material taking rod 310 outwards through the slope surface of the material taking piece 309, compressing the material taking spring 311. Subsequently, the grooved part of the material taking piece 309 reaches the outside of the metal product. At this time, an inward clamping force is provided by the material taking spring 311. Then, the vertical electric cylinder 301 ascends, driving the downward pressure arc rod 307 and the material taking frame 308 to ascend, and lifting the metal product on the lower plate 114 at the discharging station through the material taking piece 309. When the picking and placing frame 108 rotates counterclockwise by 180 degrees, the central gear 107 drives the upper gear 126, the gear column 125, and the lower gear 127 to rotate. The bottom transmission belt 128 drives the lower gear 303 and the inner rotating rod 302 to rotate, thereby driving the outer sliding rod 304, the chute turntable 306, the downward pressure arc rod 307, and the material taking frame 308 to rotate clockwise by 180 degrees, causing the material taking piece 309 to carry the metal product away from above the discharging station. At this time, the metal product clamped by the material taking piece 309 is taken out. When the picking and placing frame 108 rotates counterclockwise by 180 degrees, the downward pressure arc rod 307 rotates clockwise by 180 degrees. The downward pressure arc rod 307 is always located above the picking and placing frame 108, so that when the downward pressure arc rod 307 descends, it synchronously drives the picking and placing frame 108 to descend, and when the downward pressure arc rod 307 ascends, the picking and placing frame 108 synchronously ascends under the reset of the strong spring.

[0047] The working principle of a centrifugal casting device for metal products disclosed by the present invention is as follows: The device is provided with four working stations in sequence, namely the mold placing station, the casting station, the mold opening station, and the discharging station. The lower motor 129 drives the motor gear 130 to rotate, and drives the rod pulling column 132 and the rod pulling frame 133 to rotate 90 degrees through the transmission belt 131. When the rod pulling frame 133 rotates, through the contact between the opening chute and the rotating base frame 111, it drives the rotating frame 109 to rotate counterclockwise by 90 degrees. When the lower motor 129 does not rotate, the rotating base frame 111 is located in the opening chute of the rod pulling frame 133. At this time, the rotating frame 109 cannot rotate, that is, only when the rod pulling frame 133 rotates will it drive the rotating frame 109 to rotate, and the rotating frame 109 rotates counterclockwise by 90 degrees each time. The working station on the side of the rotating motor 201 is the casting station, and the working station on the side of the vertical electric cylinder 301 is the discharging station. After the rotating frame 109 rotates counterclockwise by 90 degrees, the rotating base frame 111 originally in the casting station reaches the mold opening station, and the rotating base frame 111 originally in the discharging station reaches the mold placing station.The vertical electric cylinder 301 contracts to drive the chute turntable 306 to descend. The inner spring 305 is compressed. The descent of the chute turntable 306 drives the downward pressure arc rod 307 and the material taking frame 308 to descend. The descent of the downward pressure arc rod 307 drives the pick-and-place column 106 to descend, thereby driving the pick-and-place frame 108 and the insertion rod 110 to descend. The upper sleeve 105, the upper inner sleeve 104, and the lower inner sleeve 103 descend, and the strong spring is compressed. The insertion rod 110 reaches the outside of the upper mold 116 at the mold opening station. At this time, the insertion rod 110 is not inserted into the docking buckle 117. Then the rotation motor 201 starts, driving the rotation gear 202 to rotate, thereby driving the driving gear 204, the outer gear column 203, the intermediate gear 205, and the docking gear 206 to rotate, thereby driving the side gear 207 and the top gear 208 to rotate. The friction wheel 212 is driven to rotate through the side transmission belt 209. The friction wheel 212 drives the self-rotating gear 113 at the mold opening station to rotate, thereby driving the rotating bottom frame 111, the lower disk 114, and the upper mold 116 to rotate, so that the insertion rod 110 is inserted into the docking buckle 117. At this time, the rotating bottom frame 111 at the casting station is not lifted by the lifting plate 123, and the self-rotating gear 113 at the casting station does not mesh with the docking gear 206, and the casting centrifugal action does not occur. Subsequently, the downward pressure arc rod 307 rises, and the pick-and-place column 106 and the pick-and-place frame 108 rise under the reset of the strong spring. The upper mold 116 at the mold opening station is lifted by the insertion rod 110, so that the cast metal product is exposed. Subsequently, the lower electric cylinder 118 extends to drive the movable rack 119 to move, thereby driving the central gear 107 and the pick-and-place frame 108 to rotate counterclockwise by 180 degrees. At this time, the pick-and-place frame 108 and the insertion rod 110 move the upper mold 116 to above the inner mold 115 at the mold placing station. Subsequently, the downward pressure arc rod 307 descends, and the upper mold 116 is placed on the lower disk 114 at the mold placing station. The upper mold 116 is matched with the lower disk 114. Then the rotation motor 201 is reversed to start, driving the rotation gear 202 to rotate, thereby driving the driving gear 204, the outer gear column 203, the intermediate gear 205, and the docking gear 206 to rotate, thereby driving the side gear 207 and the top gear 208 to rotate. The friction wheel 212 is driven to rotate through the side transmission belt 209. The friction wheel 212 drives the self-rotating gear 113 to reverse, so that the insertion rod 110 disengages from the docking buckle 117. Subsequently, the downward pressure arc rod 307 rises, causing the pick-and-place frame 108 to rise. Subsequently, the lower electric cylinder 118 contracts and resets, completing the transfer of the upper mold 116 on the lower disk 114 at the mold opening station to the lower disk 114 at the mold placing station, facilitating the discharging station to take away the cast metal product.When the blanking piece 309 contacts the metal product on the lower plate 114 at the blanking station, the metal product will push the blanking piece 309 and the blanking rod 310 outwards through the slope surface of the blanking piece 309, and the blanking spring 311 is compressed. Subsequently, the patterned part of the blanking piece 309 reaches the outside of the metal product. At this time, an inward clamping force is provided by the blanking spring 311. Then, the vertical electric cylinder 301 rises, driving the lower pressing arc rod 307 and the blanking frame 308 to rise, and lifting the metal product on the lower plate 114 at the blanking station through the blanking piece 309; when the picking and placing frame 108 rotates counterclockwise by 180 degrees, the central gear 107 drives the upper gear 126, the gear column 125 and the lower gear 127 to rotate, drives the lower gear 303 and the inner rotating rod 302 to rotate through the bottom transmission belt 128, thereby driving the outer sliding rod 304, the chute turntable 306, the lower pressing arc rod 307 and the blanking frame 308 to rotate clockwise by 180 degrees, so that the blanking piece 309 takes the metal product away from above the blanking station. At this time, the metal product clamped by the blanking piece 309 is taken out. When the picking and placing frame 108 rotates counterclockwise by 180 degrees, the lower pressing arc rod 307 rotates clockwise by 180 degrees. The lower pressing arc rod 307 is always located above the picking and placing frame 108, so that when the lower pressing arc rod 307 descends, it drives the picking and placing frame 108 to descend synchronously, and when the lower pressing arc rod 307 rises, the picking and placing frame 108 rises synchronously under the reset of the strong spring. During the process of the lower electric cylinder 118 driving the moving rack 119 to move, it will drive the rotating column 121 and the rotating arc plate 122 to rotate through the rotating rod 120, thereby driving the jacking plate 123 to move. The jacking plate 123 drives the jacking block 124 to rise through the slope surface on the upper surface. The jacking block 124 rises to drive the rotating bottom frame 111 and the self-rotating gear 113 at the casting station to rise. When the lower electric cylinder 118 extends to the longest, the jacking plate 123 completely jacks up the jacking block 124, and the self-rotating gear 113 at the casting station meshes with the docking gear 206, and the molten metal is introduced into the upper mold 116 through the pouring port of the upper mold 116. At this time, the friction wheel 212 drives the self-rotating gear 113 and the lower plate 114 to rotate for centrifugal casting. After casting is completed, during the casting process, the lower pressing arc rod 307 does not descend. During the contraction of the lower electric cylinder 118, as the rotating arc plate 122 rotates in the reverse direction, the self-rotating gear 113 and the rotating bottom frame 111 descend, and the self-rotating gear 113 at the casting station disengages from the docking gear 206. When centrifugal casting is completed and the upper mold 116 at the mold opening station is moved to the mold placing station, the pulling rod frame 133 rotates by 90 degrees, driving the rotating frame 109 to rotate counterclockwise by 90 degrees, so that the rotating bottom frame 111 originally at the mold placing station reaches the casting station, the rotating bottom frame 111 originally at the casting station reaches the mold opening station, the rotating bottom frame 111 originally at the mold opening station reaches the blanking station, and the rotating bottom frame 111 originally at the blanking station reaches the mold placing station.

[0048] That is, first, the arc rod 307 is pressed down to descend, driving the pick-and-place frame 108 to descend, so that the insertion rod 110 reaches beside the upper mold 116 at the mold opening station. Through the rotation of the upper mold 116, the insertion rod 110 is inserted into the docking buckle 117. At the same time, the material picking piece 309 clamps the metal product at the discharging station. Subsequently, the arc rod 307 and the pick-and-place frame 108 rise, lifting the upper mold 116 at the mold opening station, and the material picking piece 309 lifts the metal product. Then, the lower electric cylinder 118 extends to the longest, the pick-and-place frame 108 rotates counterclockwise by 180 degrees, the arc rod 307 rotates clockwise by 180 degrees, and the lifting plate 123 lifts the rotating bottom frame 111 at the casting station. At this time, the docking gear 206 drives the lower disk 114 at the casting station to rotate for centrifugal casting, and at the same time, the metal product clamped by the material picking piece 309 is taken out. Subsequently, the pick-and-place frame 108 descends and rotates in cooperation with the rotating bottom frame 111 at the mold placing station to place the upper mold 116 on the lower disk 114 at the mold placing station. At this time, the operation of placing the upper mold 116 at the mold placing station is completed, the centrifugal casting operation at the casting station is completed, the operation of taking away the upper mold 116 at the mold opening station is completed, and the operation of taking away the metal product at the discharging station is completed. Then, the rotating frame 109 rotates counterclockwise by 90 degrees to transfer all stations to the next station and proceed in sequence.

Any person skilled in the art within the technical scope of the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
