A push transmission belt 218 is wound around the push gear 217 and the transmission gear 216. An inner convex ball 222 is provided on the outer wall of the inner rotating column 221, and a bidirectional internal thread is provided on the inner wall of the inner bidirectional thread push column 220, and the inner convex ball 222 slides in the bidirectional internal thread of the inner bidirectional thread push column 220.

[0035] like Figure 4-Figure 8As shown, an inner through plate 225 is fixedly installed in the fixed tube 202, and a hole is set on the inner through plate 225, and a push rod 223 is slidably installed on the inner through plate 225, and a push rod spring 224 is set between the push rod 223 and the inner through plate 225, and a blocking piece 226 is fixedly installed on the push rod 223, and there is a gap between the blocking piece 226 and the inner wall of the fixed tube 202, and a blocking piece 226 is fixedly installed on the blocking piece 226, and an injection tube 227 is slidably installed with the fixed tube 202, and the injection tube 227 is an inner hollow structure, and a plurality of liquid inlet grooves are set on the injection tube 227. In the initial state, the blocking piece 226 blocks the hole on the inner through plate 225.

[0036] The stainless steel raw material block is put into the feed barrel 203, and the stainless steel is melted by the heater in the feed barrel 203, and dripped into the fixed tube 202 through the hole of the inner hole plate 204, and the bottom motor 208 drives the motor wheel 209 to rotate, and drives the upper transmission wheel 212, the lower gear shaft 211, the large gear 213 and the lower gear 230 to rotate one circle through the output belt 210, and the lower gear 230 drives the upper gear 229, the docking shaft 228 and the half-toothed outer gear ring 231 to rotate, and when the toothed part of the half-toothed outer gear ring 231 meshes with the inner gear 232, it drives the inner gear 232 and the outer gear 233 to rotate, thereby driving the docking gear 118 to rotate, and the lower gear 230 rotates one circle to drive the upper gear 229 to rotate half a circle, and finally the upper conveyor belt 108 and the lower conveyor belt 108 are connected. 4 moves once, so that the upper mold 109 and the lower mold 105 move forward one station, the large gear 213 rotates one circle to drive the push frame 219, the upper gear shaft 214 and the transmission gear 216 to rotate ten circles, the transmission gear 216 drives the push gear 217 and the inner rotating column 221 to rotate, and through the cooperation of the inner convex ball 222 and the inner double-threaded push column 220, the inner double-threaded push column 220 slides along the side bracket 201 to the farthest, and the inner double-threaded push column 220 pushes the stainless steel liquid in the fixed tube 202 toward the direction of the blocking sheet 226, and the inner double-threaded push column 220 drives the push frame 219 to move together, and as the push frame 219 moves, the top spring 207 drives the docking sleeve 206 to slide along the side guide column 205, and the pull spring 23 4 is stretched, so that the butt sleeve 206 is inserted into the outer side of the liquid inlet of the lower mold 105 and the upper mold 109. After the butt sleeve 206 is inserted, the push frame 219 continues to move forward so that the top spring 207 is compressed, so that the fixed tube 202, the butt sleeve 206 and the lower mold 105 are connected with the upper mold 109. When the inner two-way threaded push column 220 contacts the push rod 223, it pushes the push rod 223, the blocking sheet 226 and the injection tube 227 forward, and the push rod spring 224 is compressed. The blocking sheet 226 no longer blocks the hole of the inner through plate 225. The stainless steel liquid passes through the hole of the inner through plate 225 and the gap between the blocking sheet 226 and the inner wall of the fixed tube 202. Then, the stainless steel liquid is injected into the lower mold 105 and the upper mold 109 through the liquid inlet groove on the injection tube 227. In the mold 109, during the casting process, the toothless part of the half-toothed outer gear ring 231 cooperates with the internal gear 232. At this time, the lower mold 105 and the upper mold 109 will not move. Due to the bidirectional internal thread on the inner wall of the internal bidirectional thread push pin 220, when the large gear 213 continues to rotate for the second circle, the internal bidirectional thread push pin 220 retreats to the initial position, and the stainless steel liquid in the feed barrel 203 falls into the fixed tube 202. At the same time, the toothed part of the half-toothed outer gear ring 231 meshes with the internal gear 232, so that the cast lower mold 105 and the upper mold 109 are separated, and the internal bidirectional thread push pin 220 retreats at this time. Since the elastic force of the pull spring 234 is greater than the elastic force of the top spring 207, the docking sleeve 206 will quickly disengage from the lower mold 105 and the upper mold 109.The next lower mold 105 and upper mold 109 to be cast are moved to the front of the fixed tube 202 for the next casting, and continuous casting is achieved by this reciprocating process.

[0038] The movement of the upper conveyor belt 108 will drive the upper conveyor shaft 106 to rotate. When the lower mold 105 and the upper mold 109 are separated, the magnet 302 will attract the stainless steel product in the lower mold 105. When the upper conveyor shaft 106 rotates, it drives the side gear 306 to rotate, and drives the discharge gear 304, the rotating frame 301 and the magnet 302 to rotate counterclockwise through the discharge transmission belt 305. Then the magnet 302 rotates with the stainless steel product. When the stainless steel product contacts the discharge rod 303 from bottom to top, the magnet 302 is separated from the stainless steel product under the action of the discharge rod 303, thereby realizing the discharge of the stainless steel product.

[0039] The working principle of a stainless steel product continuous casting device disclosed in the present invention is as follows: a bottom motor 208 drives a motor wheel 209 to rotate, and drives an upper transmission wheel 212, a lower gear shaft 211, a large gear 213 and a lower gear 230 to rotate one circle through an output belt 210, and the lower gear 230 drives an upper gear 229, a docking shaft 228 and a half-toothed outer gear ring 231 to rotate, and when the toothed portion of the half-toothed outer gear ring 231 meshes with an inner gear 232, the inner gear 232 and the outer gear 233 are driven to rotate, thereby driving a docking gear 118 to rotate, and the docking gear 118 drives a lower driving shaft 115, a lower driving wheel 117 and a lower transmission gear 116 to rotate. The lower driving wheel 117 drives the lower conveyor belt 104 to move, and the lower transfer gear 116 drives the middle and lower gear 114 to rotate, and drives the middle and upper gear 113 to rotate, thereby driving the upper transfer gear 112, the upper driving shaft 110 and the upper driving wheel 111 to rotate, thereby driving the upper conveyor belt 108 to move. The upper conveyor belt 108 moves in opposite directions to the lower conveyor belt 104, so that when the upper mold 109 moves to the bottom of the upper conveyor belt 108, it just cooperates with the lower mold 105 located above the lower conveyor belt 104 to be closed, and the lower mold 105 is connected to the liquid inlet of the upper mold 109, and the upper conveying shaft 106 rotates to drive the side gear 306 to rotate.

The lower gear 230 drives the upper gear 229, the docking shaft 228 and the half-toothed outer gear ring 231 to rotate. When the toothed part of the half-toothed outer gear ring 231 meshes with the inner gear 232, it drives the inner gear 232 and the outer gear 233 to rotate, thereby driving the docking gear 118 to rotate. The lower gear 230 rotates one circle and drives the upper gear 229 to rotate half a circle, and finally the upper conveyor belt 108 and the lower conveyor belt 104 move once, so that the upper mold 109 and the lower mold 105 move forward one station, and the large gear 213 rotates. The push frame 219, the upper gear shaft 214 and the transmission gear 216 rotate ten circles with one circle, and the transmission gear 216 drives the push gear 217 and the inner rotating column 221 to rotate. Through the cooperation of the inner convex ball 222 and the bidirectional internal thread of the inner bidirectional thread push column 220, the inner bidirectional thread push column 220 slides to the farthest along the side bracket 201. The inner bidirectional thread push column 220 pushes the stainless steel liquid in the fixed tube 202 toward the direction of the blocking plate 226. The inner bidirectional thread push column 220 drives the push frame 219 to move together. As the push frame 219 moves, the top spring 207 drives the docking sleeve 206 to slide along the side guide column 205, and the tension spring 234 is stretched, so that the docking sleeve 206 is inserted into the outer side of the liquid inlet of the lower mold 105 and the upper mold 109. After the docking sleeve 206 is inserted, the push frame 219 continues to move forward, so that the top spring 207 is compressed.The fixed tube 202, the docking sleeve 206 and the lower mold 105 are connected with the upper mold 109. When the internal two-way threaded push column 220 contacts the push rod 223, it pushes the push rod 223, the blocking plate 226 and the injection tube 227 forward, and the push rod spring 224 is compressed. The blocking plate 226 no longer blocks the hole of the inner through plate 225. The stainless steel liquid passes through the hole of the inner through plate 225 and the gap between the blocking plate 226 and the inner wall of the fixed tube 202. Then, the stainless steel liquid is injected into the lower mold 105 and the upper mold 109 through the liquid inlet groove on the injection tube 227. During the casting process, the toothless part of the half-toothed outer gear ring 231 cooperates with the internal gear 232. At this time, the lower mold 105 and the upper mold 109 will not move. The bidirectional internal thread on the inner wall of the threaded push pin 220, when the large gear 213 continues to rotate for the second circle, the internal bidirectional threaded push pin 220 retreats to the initial position, and the stainless steel liquid in the feed barrel 203 falls into the fixed tube 202. At the same time, the toothed part of the half-toothed outer gear ring 231 is meshed with the internal gear 232, so that the cast lower mold 105 and the upper mold 109 are separated, and the internal bidirectional threaded push pin 220 retreats at this time. Since the elastic force of the pull spring 234 is greater than the elastic force of the top spring 207, the docking sleeve 206 will quickly detach from the lower mold 105 and the upper mold 109, and the next lower mold 105 and upper mold 109 to be cast move to the front of the fixed tube 202 for the next casting, thereby realizing continuous casting by reciprocating. The movement of the upper conveyor belt 108 drives the upper conveyor shaft 106 to rotate. When the lower mold 105 and the upper mold 109 are separated, the magnet 302 attracts the stainless steel product in the lower mold 105. When the upper conveyor shaft 106 rotates, it drives the side gear 306 to rotate, and drives the discharge gear 304, the rotating frame 301 and the magnet 302 to rotate counterclockwise through the discharge transmission belt 305. Then the magnet 302 rotates with the stainless steel product. When the stainless steel product contacts the discharge rod 303 from bottom to top, the magnet 302 is separated from the stainless steel product under the action of the discharge rod 303, and the stainless steel product is discharged.
