[0008] 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.

[0009] 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.

The insertion rod is not inserted into the docking buckle at this time. At this time, the friction wheel drives the self-rotating gear to rotate, thereby driving the rotating base frame, the lower plate and the upper mold to rotate, so that the insertion rod is inserted into the docking buckle. At this time, the rotating base frame at the casting station is not lifted up by the lifting plate, the self-rotating gear of the casting station does not mesh with the docking gear, and the casting centrifugal action does not proceed. Subsequently, the arc rod is pressed down to move up, and the pick-up and placement column and the pick-up and placement rack rise under the reset of the strong spring, and the upper mold on the mold opening station is lifted by the insertion rod. The upper mold is moved to the upper plate of the mold placing station, and the upper mold is placed on the lower plate of the mold placing station. The upper mold and the lower plate are matched, and then the friction wheel drives the self-rotating gear to reverse, so that the insertion rod is disengaged from the docking buckle, and then the lower arc rod rises, causing the pick-up rack to rise, and then the lower electric cylinder contracts and resets, completing the transfer of the upper mold on the lower plate of the mold opening station to the lower plate of the mold placing station, so that the unloading station can take away the cast metal product.

[0011] When the lower electric cylinder drives the movable rack to move, the rotating column and the rotating arc plate will be driven 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 of the upper surface. The lifting block rises and drives the rotating base frame and the self-rotating gear at the casting station to rise. When the lower electric cylinder is extended to the longest, the lifting plate completely lifts the lifting block, and the self-rotating gear of the casting station meshes with the docking gear, and the molten metal is passed into the upper mold through the casting port of the upper mold. At this time, the friction wheel drives the self-rotating gear and the lower plate to rotate for centrifugal casting. After the casting is completed, during the casting process, the downward pressure arc rod does not Descending, during the contraction of the lower electric cylinder, with the reverse rotation of the rotating arc plate, the self-rotating gear and the rotating base frame descend, and the self-rotating gear of the casting station is disengaged from the docking gear. After the centrifugal casting is completed and the upper mold of the mold opening station is moved to the mold releasing station, the pull rod frame rotates ninety degrees, driving the rotating frame to rotate ninety degrees counterclockwise, so that the rotating base frame originally at the mold releasing 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 discharge station, and the rotating base frame originally at the discharge station reaches the mold releasing station.

[0012] Furthermore, the rotating mechanism includes a rotating gear fixedly mounted on the motor shaft of the rotating motor, an outer gear column rotatably mounted on the base, a driving gear, an intermediate gear and a docking gear fixedly mounted on the outer gear column, two side gears rotatably mounted on the base, a top gear fixedly mounted on the side gears, the driving gear meshes with the rotating gear, the side gears mesh with the intermediate gears, a transfer transmission wheel rotatably mounted on the base, a side frame fixedly mounted on the base, a friction wheel rotatably mounted on the side frame, and a side transmission belt wrapped around the friction wheel, the transfer transmission wheel and the top gear.

[0013] When the rotating motor is started, it drives the rotating gear to rotate, thereby driving the driving gear, the outer gear column, the intermediate gear and the docking gear to rotate, thereby driving the side gear and the top gear to rotate, and driving the friction wheel to rotate through the side transmission belt. The two friction wheels are respectively meshed with the self-rotating gears of the mold placing station and the mold opening station. When the rotating base frame of the casting station is lifted up by the lifting block, the self-rotating gear of the casting station is meshed with the docking gear.

[0014] Furthermore, the taking-out mechanism includes an inner rotating rod rotatably mounted on the base, the inner rotating rod is fixedly mounted on the lower gear, an outer sliding rod is slidably mounted on the inner rotating rod, an inner spring is arranged between the outer sliding rod and the inner rotating rod, a slide groove turntable is fixedly mounted on the outer sliding rod, an arc groove is arranged on the slide groove turntable, the output end of the vertical electric cylinder slides in the arc groove of the slide groove turntable, a downward pressing arc rod is fixedly mounted on the slide groove turntable, and the lower surface of the downward pressing arc rod is in contact with the pick-up and release rack.

[0016] The vertical electric cylinder contracts and drives the slide turntable down, the inner spring is compressed, and the slide turntable descends, driving the downward pressure arc rod and the pick-up rack to descend. When the pick-up sheet contacts the metal product on the lower plate of the discharge station, the metal product will pass through the slope of the pick-up sheet, push the pick-up sheet and the pick-up rod outward, and the pick-up spring is compressed. Then the textured part of the pick-up sheet reaches the outside of the metal product. At this time, the pick-up spring provides an inward clamping force, and then the vertical electric cylinder rises, driving the downward pressure arc rod and the pick-up rack to rise, and the metal product on the lower plate of the discharge station is lifted up by the pick-up sheet; when the pick-up rack rotates 180 degrees counterclockwise, the center gear The wheel drives the upper gear, gear column and lower gear to rotate, and drives the lower gear and inner rotating rod to rotate through the bottom transmission belt, thereby driving the outer sliding rod, slide turntable, lower pressure arc rod and material picking rack to rotate 180 degrees clockwise, so that the material picking sheet takes the metal product away from the top of the unloading station. At this time, the metal product clamped by the material picking sheet is taken out, and when the pick-up rack rotates 180 degrees counterclockwise, the lower pressure arc rod rotates 180 degrees clockwise, and the lower pressure arc rod is always located above the pick-up rack, so that when the lower pressure arc rod descends, the pick-up rack is synchronously driven to descend, and when the lower pressure arc rod rises, the pick-up rack rises synchronously under the reset of the strong spring.

[0017] That is, first, the arc rod is pressed down to drive the pick-up and place rack to descend, so that the insertion rod reaches the upper mold of the mold opening station, and the insertion rod is inserted into the docking buckle through the rotation of the upper mold. At the same time, the material sheet is taken to clamp the metal product at the discharge station. Then, the arc rod and the pick-up and place rack rise to lift the upper mold of the mold opening station, and the material sheet is taken to lift the metal product. Then, the lower electric cylinder is extended to the longest, the pick-up and place rack rotates 180 degrees counterclockwise, the arc rod rotates 180 degrees clockwise, and the lifting plate lifts 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 takes out the metal product clamped by the material taking sheet, then the pick-up and placement rack descends, and cooperates with the rotating base frame of the mold placing station to rotate, and places the upper mold on the lower plate of the mold placing station. At this time, the upper mold placement action of the mold placing station is completed, the centrifugal casting action of the casting station is completed, the upper mold of the mold opening station is removed, and the metal product of the material discharging station is removed. Then the rotating rack rotates ninety degrees counterclockwise to transfer all stations to the next station, and proceed in sequence.

[0036] like Figure 2-Figure 6 As shown, the toggle module includes a lower motor 129 fixedly mounted on the base 101, a motor gear 130 fixedly mounted on the motor shaft of the lower motor 129, a lever column 132 rotatably mounted on the base 101, a lever frame 133 fixedly mounted on the lever column 132, four open slide grooves are provided on the lever frame 133, and a transmission belt 131 is wrapped around the lever column 132 and the motor gear 130.

[0037] The device is provided with four stations, namely, the mold placing station, the casting station, the mold opening station and the material 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, the contact between the open slide and the rotating base frame 111 drives the rotating frame 109 to rotate 90 degrees counterclockwise. When the lower motor 129 does not rotate, the rotating base frame 111 is located at the opening of the rod pulling frame 133. In the slide groove, the rotating frame 109 cannot rotate at this time, that is, the rotating frame 109 can only be driven to rotate when the pull rod frame 133 rotates, and the rotating frame 109 rotates ninety degrees counterclockwise each time.

After the rotating frame 109 rotates ninety degrees counterclockwise, the rotating base frame 111 originally at the casting station arrives at the mold opening station, and the rotating base frame 111 originally at the unloading station arrives at the mold releasing station.

[0038] By pressing the arc rod 307 downward, the pick-up and placement column 106 is driven to move downward, thereby driving the pick-up and placement rack 108 and the insertion rod 110 to move downward, the upper sleeve 105, the upper inner sleeve 104, and the lower inner sleeve 103 are lowered, the strong spring is compressed, and the insertion rod 110 reaches the outer side of the upper mold 116 located at the mold opening station. The insertion rod 110 is not inserted into the docking buckle 117 at this time. At this time, the friction wheel 212 drives the self-rotating gear 113 to rotate, thereby driving the rotating base frame 111, the lower plate 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 base frame 111 located at the casting station is not lifted up by the lifting plate 123, the self-rotating gear 113 of the casting station does not mesh with the docking gear 206, and the casting centrifugal action does not proceed. Subsequently, the arc rod 307 is pressed downward to rise, the pick-up and placement column 106 and the pick-up and placement rack 108 rise under the reset of the strong spring, and the upper The mold 116 is lifted, so that the cast metal product is exposed, and then the lower electric cylinder 118 is extended to drive the movable rack 119 to move, thereby driving the central gear 107 and the pick-up and placement rack 108 to rotate counterclockwise by 180 degrees.

The upper mold 116 and the lower plate 114 are matched, and then the friction wheel 212 drives the self-rotating gear 113 to reverse, so that the insertion rod 110 is disengaged from the docking buckle 117, and then the lower arc rod 307 is raised, so that the pick-up and placement rack 108 is raised, and then the lower electric cylinder 118 is retracted and reset, completing the transfer of the upper mold 116 on the lower plate 114 of the mold opening station to the lower plate 114 of the mold placement station, so that the unloading station can take away the cast metal product.

[0039] When the lower electric cylinder 118 drives the movable rack 119 to move, the rotating column 121 and the rotating arc plate 122 will be driven to rotate through the rotating rod 120, thereby driving the lifting plate 123 to move. The lifting plate 123 drives the lifting block 124 to rise through the slope of the upper surface. The lifting block 124 rises and drives the rotating base frame 111 and the self-rotating gear 113 located at the casting station to rise. When the lower electric cylinder 118 is extended to the longest, the lifting plate 123 completely lifts the lifting block 124, and the self-rotating gear 113 of the casting station is meshed with the docking gear 206, and the molten metal is passed into the upper mold 116 through the casting port of the upper mold 116.

[0043] like Fig. 9 , Fig.10 As shown, a material picking rack 308 is fixedly installed below the downward pressure arc rod 307, and a number of material picking rods 310 are slidably installed on the material picking rack 308. A material picking sheet 309 is fixedly installed on the material picking rod 310, and the material picking sheet 309 is provided with a pattern to increase friction. A material picking spring 311 is provided between the material picking sheet 309 and the material picking rack 308, and the material picking sheet 309 is provided with a slope.

[0044] The vertical electric cylinder 301 contracts and drives the slide turntable 306 to descend, the inner spring 305 is compressed, and the slide turntable 306 descends and drives the downward pressure arc rod 307 and the material picking rack 308 to descend. When the material picking sheet 309 contacts the metal product on the lower plate 114 of the discharging station, the metal product will pass through the slope of the material picking sheet 309, push the material picking sheet 309 and the material picking rod 310 outward, and the material picking spring 311 is compressed. Then the textured part of the material picking sheet 309 reaches the outside of the metal product. At this time, the material picking spring 311 provides an inward clamping force, and then the vertical electric cylinder 301 rises and drives the downward pressure arc rod 307 and the material picking rack 308 to rise, and the metal product on the lower plate 114 of the discharging station is lifted up by the material picking sheet 309; when the pick-up rack 108 rotates 180 degrees counterclockwise, the center gear 1 07 drives the upper gear 126, the gear column 125 and the lower gear 127 to rotate, and 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 slide groove turntable 306, the downward pressing arc rod 307 and the material picking rack 308 to rotate 180 degrees clockwise, so that the material picking sheet 309 takes the metal product away from the top of the unloading station. At this time, the metal product clamped by the material picking sheet 309 is taken out, and when the picking rack 108 rotates 180 degrees counterclockwise, the downward pressing arc rod 307 rotates 180 degrees clockwise, and the downward pressing arc rod 307 is always located above the picking rack 108, so that when the downward pressing arc rod 307 descends, it synchronously drives the picking rack 108 to descend, and when the downward pressing arc rod 307 rises, the picking rack 108 rises synchronously under the reset of the strong spring.

[0045] The working principle of a centrifugal casting device for metal products disclosed in the present invention is as follows: the device is provided with four stations, namely, a mold placing station, a casting station, a mold opening station and a material discharging station, a lower motor 129 drives a motor gear 130 to rotate, and drives a rod pulling column 132 and a rod pulling frame 133 to rotate ninety degrees through a transmission belt 131, and when the rod pulling frame 133 rotates, the contact between the open chute and the rotating base frame 111 drives the rotating frame 109 to rotate ninety degrees counterclockwise, and when the lower motor 129 does not rotate, the rotating base frame 111 1 is located in the open slide groove of the rod pulling frame 133. At this time, the rotating frame 109 cannot rotate, that is, the rotating frame 109 can only be driven to rotate when the rod pulling frame 133 rotates, and the rotating frame 109 rotates 90 degrees counterclockwise each time. The station located on the side of the rotating motor 201 is the casting station, and the station located on the side of the vertical electric cylinder 301 is the unloading station. After the rotating frame 109 rotates 90 degrees counterclockwise, the rotating base frame 111 originally at the casting station arrives at the mold opening station, and the rotating base frame 111 originally at the unloading station arrives at the mold placing station.The vertical electric cylinder 301 contracts and drives the slide turntable 306 to descend, the inner spring 305 is compressed, the slide turntable 306 descends and drives the downward pressure arc rod 307 and the material picking rack 308 to descend, and the downward pressure arc rod 307 descends, driving the pick-up and placement column 106 to descend, thereby driving the pick-up and placement rack 108 and the insertion rod 110 to descend, the upper sleeve 105, the upper inner sleeve 104, and the lower inner sleeve 103 to descend, the strong spring is compressed, and the insertion rod 110 reaches the outer side of the upper mold 116 located at the mold opening station. The insertion rod 110 is not inserted into the docking buckle 117 at this time, and the rotating motor 201 is started at this time, driving the rotating gear 202 to rotate, thereby driving the active gear 204 and the outer gear column 203, the middle gear 205 and the docking gear 206 rotate, thereby driving the side gear 207 and the top gear 208 to rotate, and the friction wheel 212 rotates through the side transmission belt 209, and the friction wheel 212 drives the self-rotating gear 113 of the mold opening station to rotate, thereby driving the rotating base frame 111, the lower plate 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 base frame 111 located at the casting station is not lifted up by the lifting plate 123, the self-rotating gear 113 of the casting station does not mesh with the docking gear 206, and the casting centrifugal action does not proceed. Subsequently, the downward pressing arc rod 307 rises, and the pick-up and placement column 106 and the pick-up and placement frame 1 08 rises under the reset of the strong spring, and lifts the upper mold 116 on the mold opening station through the insertion rod 110, so that the cast metal product is exposed, and then the lower electric cylinder 118 extends to drive the movable rack 119 to move, thereby driving the central gear 107 and the pick-up and placement rack 108 to rotate 180 degrees counterclockwise. At this time, the pick-up and placement rack 108 and the insertion rod 110 move the upper mold 116 to the top of the inner mold 115 of the mold placement station, and then the lower arc rod 307 descends to place the upper mold 116 on the lower plate 114 located at the mold placement station. The upper mold 116 and the lower plate 114 are matched, and the rotating motor 201 is reversed and started to drive The rotating gear 202 rotates, thereby driving the driving gear 204, the outer gear column 203, the middle gear 205 and the docking gear 206 to rotate, thereby driving the side gear 207 and the top gear 208 to rotate, and the friction wheel 212 is driven to rotate through the side transmission belt 209, and the friction wheel 212 drives the self-rotating gear 113 to reverse, so that the insertion rod 110 disengages from the docking buckle 117, and then the arc rod 307 is pressed down to rise, so that the pick-up and release rack 108 rises, and then the lower electric cylinder 118 shrinks and resets, completing the transfer of the upper mold 116 on the lower plate 114 of the mold opening station to the lower plate 114 of the mold placing station, so that the unloading station can take away the cast metal product.When the material picking sheet 309 contacts the metal product on the lower plate 114 of the discharging station, the metal product will pass through the slope of the material picking sheet 309, push the material picking sheet 309 and the material picking rod 310 outward, and the material picking spring 311 will be compressed. Then the textured part of the material picking sheet 309 reaches the outside of the metal product. At this time, the inward clamping force is provided by the material picking spring 311, and then the vertical electric cylinder 301 rises to drive the downward pressure arc rod 307 and the material picking rack 308 to rise, and the metal product on the lower plate 114 of the discharging station is lifted up by the material picking sheet 309; when the pick-up rack 108 rotates 180 degrees counterclockwise, the center gear 107 drives the upper gear 126, the gear column 125 and the lower gear 127 to rotate, and through 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 slide groove turntable 306, the downward pressing arc rod 307 and the material picking rack 308 to rotate clockwise one hundred and eighty degrees, so that the material picking sheet 309 takes the metal product away from the top of the unloading station. At this time, the metal product clamped by the material picking sheet 309 is taken out, and when the picking rack 108 rotates counterclockwise one hundred and eighty degrees, the downward pressing arc rod 307 rotates clockwise one hundred and eighty degrees, and the downward pressing arc rod 307 is always located above the picking rack 108, so that when the downward pressing arc rod 307 descends, it synchronously drives the picking rack 108 to descend, and when the downward pressing arc rod 307 rises, the picking rack 108 rises synchronously under the reset of the strong spring. When the lower electric cylinder 118 drives the movable rack 119 to move, the rotating column 121 and the rotating arc plate 122 will be driven to rotate through the rotating rod 120, thereby driving the lifting plate 123 to move. The lifting plate 123 drives the lifting block 124 to rise through the slope of the upper surface. The lifting block 124 rises and drives the rotating base frame 111 and the self-rotating gear 113 located at the casting station to rise. When the lower electric cylinder 118 is extended to the longest, the lifting plate 123 completely lifts the lifting block 124, and the self-rotating gear 113 of the casting station is meshed with the docking gear 206, and the molten metal is passed 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 plate 114 to rotate, and centrifugal casting is performed. After the casting is completed, During the casting process, the downward pressure arc rod 307 does not descend. During the contraction of the lower electric cylinder 118, as the rotating arc plate 122 rotates in the opposite direction, the self-rotating gear 113 and the rotating base frame 111 descend, and the self-rotating gear 113 of the casting station is disengaged from the docking gear 206. After the centrifugal casting is completed and the upper mold 116 of the mold opening station is moved to the mold releasing station, the pull rod frame 133 rotates ninety degrees, driving the rotating frame 109 to rotate ninety degrees counterclockwise, so that the rotating base frame 111 originally at the mold releasing station reaches the casting station, the rotating base frame 111 originally at the casting station reaches the mold opening station, the rotating base frame 111 originally at the mold opening station reaches the discharge station, and the rotating base frame 111 originally at the discharge station reaches the mold releasing station.

[0046] That is, first, the arc rod 307 is pressed down to drive the pick-up and placement rack 108 to move down, so that the insertion rod 110 reaches the upper mold 116 of the mold opening station, and the upper mold 116 is rotated to insert the insertion rod 110 into the docking buckle 117, and the material sheet 309 is used to clamp the metal product at the discharge station. Then, the arc rod 307 and the pick-up and placement rack 108 are raised to lift the upper mold 116 of the mold opening station, and the material sheet 309 lifts the metal product. Then, the lower electric cylinder 118 is extended to the longest, the pick-up and placement rack 108 rotates 180 degrees counterclockwise, and the arc rod 307 rotates 180 degrees clockwise, and the lifting plate 123 lifts the casting station. The rotating base frame 111 is lifted up, and at this time, the docking gear 206 drives the lower plate 114 of the casting station to rotate for centrifugal casting, and at the same time, the metal product clamped by the material taking sheet 309 is taken out, and then the pick-up and placement frame 108 descends, and cooperates with the rotating base frame 111 of the mold placing station to rotate, and the upper mold 116 is placed on the lower plate 114 of the mold placing station. At this time, the placement of the upper mold 116 at the mold placing station is completed, the centrifugal casting action of the casting station is completed, the upper mold 116 of the mold opening station is removed, and the metal product of the discharging station is removed. Then the rotating frame 109 rotates ninety degrees counterclockwise to transfer all stations to the next station, and proceed in sequence.
