The mold conveyor belt drives the mold conveyor wheel and the inner docking gear to rotate, thereby driving the outer docking gear and the transfer conveyor wheel to rotate, thereby driving the lifting conveyor belt to move. The stainless steel raw materials are transported to the feed hopper through the lifting conveyor belt and the conveyor plate, and the stainless steel raw materials enter the feed hopper.

[0007] Furthermore, the casting mechanism includes a bottom motor fixedly installed next to the bracket, a motor wheel is fixedly installed on the motor shaft of the bottom motor, a lower gear shaft is rotatably installed below the material distribution plate, a rear half-tooth gear, an intermediate gear, a middle half-tooth gear, a front half-tooth gear and an input gear are fixedly installed on the lower gear shaft, an active transmission belt is wrapped around the input gear and the motor wheel, a driven transmission belt is wrapped around the intermediate gear, a transfer gear is rotatably installed below the material distribution plate, the transfer gear is meshed with the rear half-tooth gear, and a vertical transmission belt is wrapped around the transfer gear and the protruding gear.

[0008] Furthermore, a material-dividing gear turntable is rotatably installed in the material-dividing disk, and teeth are arranged at the bottom of the material-dividing gear turntable. An internal gear and an internal pinion are rotatably installed below the material-dividing disk. The internal gear meshes with the middle half-tooth gear, the internal gear meshes with the internal pinion, and the internal pinion meshes with the material-dividing gear turntable.

[0009] Furthermore, an outer gear and an outer upper gear are rotatably installed under the distribution plate, the outer gear is meshed with the outer upper gear, and the outer gear is meshed with the front half-tooth gear, an inner rotating shaft is rotatably installed on the distribution plate, an inner rotating gear is fixedly installed on the inner rotating shaft, the inner rotating gear is meshed with the outer upper gear, an inner bidirectional threaded rod is slidably installed on the distribution plate, a closing plate is fixedly installed on the inner bidirectional threaded rod, the closing plate is slidably installed with the injection barrel, a pushing cavity is provided on the inner bidirectional threaded rod, a bidirectional internal thread is provided in the inner bidirectional threaded rod, a convex ball is fixedly installed on the inner rotating shaft, and the convex ball slides in the bidirectional internal thread of the inner bidirectional threaded rod.

[0010] The bottom motor drives the motor wheel to rotate, and drives the input gear, front half-tooth gear, middle half-tooth gear, lower gear shaft, intermediate gear and rear half-tooth gear to rotate through the active transmission belt. The intermediate gear drives the outer transmission gear to rotate through the driven transmission belt. When the middle half-tooth gear meshes with the inner gear, the rear half-tooth gear meshes with the transmission gear, and the front half-tooth gear disengages from the outer gear. After the stainless steel raw material enters the feed hopper, it falls onto the upper surface of the material-diverting tooth turntable in the material-dividing plate. The middle half-tooth gear drives the inner gear to rotate, drives the inner pinion to rotate, thereby drives the material-diverting tooth turntable to rotate, and diverts the metal raw material into the pushing cavity through the material-diverting tooth turntable. At the same time, the rear half-tooth gear drives the transmission gear to rotate, and drives the extending gear to rotate once through the vertical transmission belt. Each rotation of the extending gear drives the casting mold forward once, so that the casting mold that has been cast leaves the bottom of the injection cylinder, and the next casting mold to be cast arrives under the injection cylinder. At this time, the outer gear does not rotate, and the inner two-way threaded rod does not move. Then the front half-tooth gear The outer gear starts to mesh with the outer gear, the middle half-tooth gear disengages from the inner gear, and the rear half-tooth gear disengages from the transmission gear. At this time, the casting mold and the material-dividing gear turntable do not move, and the front half-tooth gear drives the outer gear to rotate, thereby driving the inner rotating gear and the inner rotating shaft to rotate through the outer upper gear, thereby driving the inner two-way threaded rod to slide along the material dividing plate through the convex ball, and the inner two-way threaded rod slides toward the injection cylinder, so that the closing plate leaves the top of the injection cylinder. At this time, the injection cylinder is opened, and the pushing cavity pushes the stainless steel raw material inside it into the injection cylinder and falls onto the blanking baffle. The heater in the injection cylinder heats and melts the stainless steel raw material, and then the molten metal drips into the casting mold from the holes in the blanking baffle for casting. The outer gear rotates once to drive the inner two-way threaded rod to move back and forth, and when the outer gear is disengaged from the front half-tooth gear, the inner two-way threaded rod returns to the initial position, and the closing plate continues to close the top of the injection cylinder. When the casting mold is not lifted, under the action of the closing spring, the closing disk closes the bottom of the injection cylinder.

[0011] Furthermore, the docking mechanism includes a camshaft rotatably mounted on the mold conveying frame, a cam and an external transfer gear are fixedly mounted on the camshaft, a driven transmission belt is wrapped around the external transfer gear and the intermediate gear, a top frame is slidably mounted on the side of the mold conveying frame, a side spring is arranged between the top frame and the mold conveying frame, a top arc block is fixedly mounted on the top frame, a lifting plate is slidably mounted on the side bracket, a lower arc plate is fixedly mounted below the lifting plate, the lower arc plate cooperates with the top arc block, and the top frame cooperates with the cam.

In the initial state, the closing disk closes the liquid outlet of the injection cylinder.

[0013] When the casting mold reaches the bottom of the injection cylinder, the casting mold is located above the lifting plate, and the external transmission gear drives the camshaft and the cam to rotate. The cam pushes the top frame to slide along the mold conveying frame, and the side spring is compressed. The top frame lifts the lower arc plate and the top through the lifting arc block, and the lifting plate lifts the casting mold. The casting mold is docked with the bottom of the injection cylinder, and the lifting column is lifted through the partition hole plate, so that the closing disk rises, and the closing spring is compressed. At this time, the stainless steel liquid in the injection cylinder enters the casting mold, and then as the cam continues to rotate, the top frame resets under the rebound of the side spring. When the inner bidirectional threaded rod slides, the cam rotates the first half of a circle, and the lifting plate pushes the casting mold upward and descends under the action of gravity, so that the lifting plate and the casting mold can rise and fall at one time, and the casting action is realized. When the mold conveyor belt, the lifting conveyor belt and the material feeding tooth turntable move, the cam rotates the second half of a circle, and the lifting plate does not rise or fall at this time.

[0014] That is, when the inner bidirectional threaded rod moves, the lifting plate drives the casting mold to rise and dock with the injection cylinder for casting operation, and then the casting mold is lowered and reset. At this time, the mold conveyor belt, lifting conveyor belt and material-diverting tooth turntable do not move; when the mold conveyor belt, lifting conveyor belt and material-diverting tooth turntable move, the inner bidirectional threaded rod does not move, the lifting plate does not move, and the casting mold is switched and the stainless steel raw materials are fed.

At the same time, the rear half-tooth gear 216 drives the transmission gear 217 to rotate, and drives the extending gear 117 to rotate once through the vertical transmission belt 226. Each rotation of the extending gear 117 drives the casting mold 107 to move forward once, so that the casting mold 107 that has been casted leaves the bottom of the injection cylinder 203, and the next casting mold 107 to be cast arrives under the injection cylinder 203. At this time, the outer gear 222 does not rotate, the inner bidirectional threaded rod 209 does not move, and then the front half-tooth gear 216 drives the transmission gear 217 to rotate, and drives the extending gear 117 to rotate once through the vertical transmission belt 226. The gear 220 starts to mesh with the outer gear 222, the middle half-tooth gear 219 disengages from the inner gear 223, and the rear half-tooth gear 216 disengages from the transfer gear 217.

At this time, the injection barrel 203 is opened and the pushing cavity 210 The stainless steel raw material inside is pushed into the injection barrel 203 and falls onto the blanking baffle 312. The heater in the injection barrel 203 heats and melts the stainless steel raw material. Then the molten metal drips from the holes of the blanking baffle 312 into the casting mold 107 for casting. The outer gear 222 rotates once to drive the inner bidirectional threaded rod 209 to move back and forth. When the outer gear 222 disengages from the front half-tooth gear 220, the inner bidirectional threaded rod 209 returns to the initial position, and the closing plate 208 continues to close the top of the injection barrel 203. When the casting mold 107 is not lifted, the closing disk 310 closes the bottom of the injection barrel 203 under the action of the closing spring 311.

[0037] like Figure 9-11As shown, the docking mechanism includes a camshaft 302 rotatably mounted on the mold conveying frame 101, a cam 304 and an external transfer gear 303 are fixedly mounted on the camshaft 302, a driven transmission belt 227 is wound around the external transfer gear 303 and the intermediate gear 218, a top frame 305 is slidably mounted on the side of the mold conveying frame 101, a side spring 306 is arranged between the top frame 305 and the mold conveying frame 101, a top arc block 307 is fixedly mounted on the top frame 305, a lifting plate 308 is slidably mounted on the side bracket 301, a lower arc plate 313 is fixedly mounted below the lifting plate 308, the lower arc plate 313 cooperates with the top arc block 307, and the top frame 305 cooperates with the cam 304.

[0038] like Figure 9-11 As shown, a lifting column 309 is slidably installed in the injection cylinder 203, a closing disk 310 is fixedly installed on the lifting column 309, a closing spring 311 is arranged between the lifting column 309 and the injection cylinder 203, a blanking baffle 312 is fixedly installed in the injection cylinder 203, a plurality of holes are arranged on the blanking baffle 312, and there is a gap between the closing disk 310 and the inner wall of the liquid outlet of the injection cylinder 203. In the initial state, the closing disk 310 closes the liquid outlet of the injection cylinder 203.

[0039] When the casting mold 107 reaches the bottom of the injection cylinder 203, the casting mold 107 is located above the lifting plate 308, the external transmission gear 303 drives the camshaft 302 and the cam 304 to rotate, the cam 304 pushes the top frame 305 to slide along the mold conveying frame 101, the side spring 306 is compressed, the top frame 305 lifts the lower arc plate 313 and the lifting plate 308 lifts the casting mold 107, the casting mold 107 is docked with the bottom of the injection cylinder 203, the lifting column 309 is lifted through the partition hole plate 118, so that the closing disk 310 rises, and the closing spring 311 is compressed.

Then, as the cam 304 continues to rotate, the top frame 305 is reset under the rebound of the side spring 306. When the inner bidirectional threaded rod 209 slides, the cam 304 rotates the first half of a circle, and the lifting plate 308 pushes the casting mold 107 upward and descends under the action of gravity, so that the lifting plate 308 and the casting mold 107 rise and fall at one time to realize the casting action. When the mold conveyor belt 105, the lifting conveyor belt 112 and the material-feeding tooth turntable 214 move, the cam 304 rotates the second half of a circle, and the lifting plate 308 does not rise or fall at this time.

[0040] That is, when the inner bidirectional threaded rod 209 moves, the lifting plate 308 drives the casting mold 107 to rise and dock with the injection cylinder 203 to carry out the casting operation, and then the casting mold 107 descends and resets. At this time, the mold conveyor belt 105, the lifting conveyor belt 112, and the material-dividing tooth turntable 214 do not move; when the mold conveyor belt 105, the lifting conveyor belt 112, and the material-dividing tooth turntable 214 move, the inner bidirectional threaded rod 209 does not move, the lifting plate 308 does not move, and the casting mold 107 is switched and the stainless steel raw material is fed.

At the same time, the rear half-tooth gear 216 drives the transfer gear 217 to rotate, and drives the extending gear 117 to rotate once through the vertical transmission belt 226. The extending gear 117 drives the extending shaft 116 and the lower driving wheel 104 to rotate, thereby driving the mold conveyor belt 105 to move. The mold conveyor belt 105 conveys the casting mold 107. The mold conveyor belt 105 drives the mold conveying wheel 103 and the inner docking gear 111 to rotate, thereby driving the outer docking gear 110 and the transfer conveying wheel 109 to rotate, thereby driving the lifting conveyor belt 112 to move, and the stainless steel raw material is transported to the feed hopper 201 through the lifting conveyor belt 112 and the conveying plate 113. The stainless steel raw material enters the feed hopper 201.Each time the extended gear 117 rotates, the casting mold 107 is driven forward once, so that the casting mold 107 that has been cast leaves the bottom of the injection cylinder 203, and the next casting mold 107 to be cast arrives under the injection cylinder 203. At this time, the outer gear 222 does not rotate, and the inner bidirectional threaded rod 209 does not move. Then the front half-tooth gear 220 begins to mesh with the outer gear 222, the middle half-tooth gear 219 disengages from the inner gear 223, and the rear half-tooth gear 216 disengages from the transmission gear 217. At this time, the casting mold 107 and the material-diverting gear turntable 214 do not move, and the front half-tooth gear 220 drives the outer gear 222 to rotate, thereby driving the inner rotating gear 213 and the inner rotating shaft 211 to rotate through the outer upper gear 224. , thereby driving the inner bidirectional threaded rod 209 to slide along the material distribution plate 202 through the convex ball 212, and the inner bidirectional threaded rod 209 slides toward the injection cylinder 203, so that the closing plate 208 leaves the top of the injection cylinder 203. At this time, the injection cylinder 203 is opened, and the pushing cavity 210 pushes the stainless steel raw material therein into the injection cylinder 203 and falls onto the blanking baffle 312. The heater in the injection cylinder 203 heats and melts the stainless steel raw material, and then the molten metal drips into the casting mold 107 from the holes of the blanking baffle 312 for casting. The outer gear 222 rotates once to drive the inner bidirectional threaded rod 209 to move back and forth. When the outer gear 222 is out of mesh with the front half-tooth gear 220, the inner bidirectional threaded rod 209 returns to In the initial position, the closing plate 208 continues to close the top of the injection cylinder 203. When the casting mold 107 is not lifted, the closing plate 310 closes the bottom of the injection cylinder 203 under the action of the closing spring 311. At the same time, when the casting mold 107 reaches the bottom of the injection cylinder 203, the casting mold 107 is located above the lifting plate 308, and the external transmission gear 303 drives the cam shaft 302 and the cam 304 to rotate. The cam 304 pushes the top frame 305 to slide along the mold conveying frame 101, and the side spring 306 is compressed. The top frame 305 lifts the lower arc plate 313 and the lifting plate 308 lifts the casting mold 107, and the casting mold 107 is docked with the bottom of the injection cylinder 203. The partition hole plate 118 lifts the lifting column 309, so that the closing disk 310 rises and the closing spring 311 is compressed. At this time, the stainless steel liquid injected into the cylinder 203 enters the casting mold 107. Then, as the cam 304 continues to rotate, the top frame 305 is reset under the rebound of the side spring 306. When the inner bidirectional threaded rod 209 slides, the cam 304 rotates the first half of a circle, and the lifting plate 308 pushes the casting mold 107 upward and descends under the action of gravity, so that the lifting plate 308 and the casting mold 107 rise and fall at one time, realizing the casting action. When the mold conveyor belt 105, the lifting conveyor belt 112 and the material-feeding tooth turntable 214 move, the cam 304 rotates the second half of a circle, and the lifting plate 308 does not rise or fall at this time.
