[0017] In actual application, the raw material is conveyed into the extrusion die 101, then the extrusion assembly 2 is controlled to operate, the raw material in the extrusion die 101 is extruded and formed, then the extrusion assembly 2 is reset, at this time, the connecting plate 312 is controlled to move upward, the connecting plate 312 drives the pushing rod 313 and the pushing block 314 to move upward at the same time, the pushing block 314 drives the extruded refractory nozzle to move upward, so that the refractory nozzle is moved out of the extrusion die 101, when the pushing block 314 drives the refractory nozzle to move upward to the limit position, at this time, the sliding frame 322 slides in the sliding seat 321, the sliding frame 322 drives the first conveying frame 323 to move, so that the two first conveying frames 323 move to the two sides below the refractory nozzle, then the pushing rod 313 and the pushing block 314 are controlled to descend, in the process of descending of the pushing block 314, the formed refractory nozzle is separated from the pushing block 314 and supported on the first conveying belt 326, when the pushing rod 313 is extracted from the refractory nozzle, at this time, the first motor 327 is controlled to operate, the first motor 327 drives the first rotating shaft 324 and the first conveying roller 325 to rotate through the first driving shaft 328 and the first sprocket set 329, the first conveying roller 325 drives the first conveying belt 326 to rotate, so that the refractory nozzle supported on the first conveying belt 326 moves to the right side, the effect of automatic demolding and discharging is achieved, when the pushing rod 313 and the pushing block 314 are reset, the sliding frame 322 is reset on the sliding seat 321 at the same time, then the refractory nozzle can be continuously machined in the extrusion die 101.

[0018] As shown in Figure 8 and 9 in an embodiment, the reset frame 4 is slidably connected in the rack 1 through the guide shaft 402, the reset block 401 is installed at the lower end of the sliding frame 322, and the reset block 401 is slidably connected with the reset frame 4.

[0019] In actual application, when the connecting plate 312 rises, the pushing rod 313, the pushing block 314 and the reset frame 4 can be synchronously driven to move upward, so that the refractory nozzle is pushed upward, when the connecting plate 312 descends, the pushing rod 313, the pushing block 314 and the reset frame 4 can be driven to move downward and reset, when the pushing rod 313 is separated from the refractory nozzle in the process of descending, at this time, the reset frame 4 pushes the reset block 401 to move rightward in the process of descending, the reset block 401 drives the sliding frame 322 to move rightward in the sliding seat 321, when the connecting plate 312 descends to the limit position and resets, at this time, the reset frame 4 drives the sliding frame 322 to move rightward to reset through the reset block 401, so that the first conveying frame 323 moves rightward and moves away from the extrusion die 101, so that the operation of the extrusion assembly 2 is not affected.

[0020] As shown in Figure 8 , 13As shown in 14, 15 and 16, in one embodiment, a slot 5 is provided on the circumferential surface of the sliding frame 322, a groove 501 is provided in the sliding seat 321, a block 502 is slidably connected in the groove 501, a first spring 503 is installed between the block 502 and the groove 501, the blocks 502 are connected by a connecting rod 504, a lifting frame 505 is installed at the upper end of the reset frame 4, the lifting frame 505 is used to push the connecting rod 504 upward, a second spring 506 is installed between the sliding frame 322 and the sliding seat 321, and a buffer pad 507 is installed on the surface of the sliding seat 321.

[0021] In practical application, when the connecting plate 312 drives the reset frame 4 to move upward, the reset frame 4 will drive the lifting frame 505 to move upward. When the connecting plate 312 is about to move to its limit position, the lifting frame 505 will push the connecting rod 504 upward. The connecting rod 504 will drive the locking block 502 to move upward in the slide groove 501, causing the locking block 502 to disengage from the slot 5. At this time, through the action of the second spring 506, the sliding frame 322 can be pushed to the left in the sliding seat 321, so that the first conveying frame 323 moves onto the extrusion mold 101 and is located below the ejected refractory nozzle. Subsequently, when the connecting plate 312 drives the push rod 313 and the push block 314 to descend and reset, the refractory nozzle can be driven to descend synchronously, so that the refractory nozzle is supported on the first conveyor belt 326. Then the connecting plate 312 The descent of the material pusher 313 causes the reset frame 4 to descend synchronously. When the pusher 313 is completely disengaged from the refractory nozzle, the reset frame 4, with the cooperation of the reset block 401, pushes the sliding frame 322 to move to the right within the sliding seat 321, causing the first conveyor frame 323 to be removed from the extrusion mold 101. After the connecting plate 312 is reset, the sliding frame 322 is reset synchronously through the action of the reset frame 4 and the reset block 401. When the sliding frame 322 is reset, the first spring 503 pushes the locking block 502 back into the locking slot 5, locking the current position of the sliding frame 322 and preventing the sliding frame 322 from moving. Only when the refractory nozzle is pushed out to the final position can the sliding frame 322 drive the first conveyor frame 323 to move to the right, thus achieving the effect of automatic demolding and unloading of the extruded refractory nozzle.

[0022] like Figure 2 As shown, in one embodiment, a cylinder 6 is installed at the lower end of the guide frame 311, and the output end of the cylinder 6 is fixedly connected to the connecting plate 312.

[0023] In practical applications, the embodiment of the present invention controls the operation of the cylinder 6, which in turn drives the connecting plate 312 to rise and fall, thereby achieving the effect of controlling the operation of the demolding component 3.

[0024] like Figure 10 and 11As shown, in one embodiment, the upper end of the rack 1 is provided with a second conveying frame 7, the second conveying frame 7 is slidably connected with the sliding frame 322, a second rotating shaft 701 is rotatably connected in the second conveying frame 7, a second conveying roller 702 is installed on the circumferential surface of the second rotating shaft 701, a second conveying belt 703 is connected between the second conveying rollers 702, a second motor 704 is installed at the lower end of the second conveying frame 7, a second driving shaft 705 is installed at the output end of the second motor 704, and the second driving shaft 705 is connected with the second rotating shaft 701 through a second sprocket set 706.

[0025] In actual application, when the sliding frame 322 moves to the right, the second motor 704 is controlled to operate, and the second motor 704 drives the second conveying belt 703 to move through the second rotating shaft 701 and the second conveying roller 702, so that the refractory nozzle conveyed on the first conveying belt 326 can be transferred to the second conveying belt 703, and then the refractory nozzle is continuously conveyed through the second conveying belt 703, thereby realizing the effect of automatically conveying the refractory nozzle to the tray for storage.

[0026] As shown in FIGS. Figure 2 , 4 and 12, in one embodiment, a fixed frame 707 is installed at the upper end of the rack 1, a servo motor 708 is installed at the lower end of the fixed frame 707, a rotating rod 709 is installed at the output end of the servo motor 708, a positioning block 7010 is installed at the upper end of the rotating rod 709, and a storage tray 7011 is placed on the positioning block 7010, and a plurality of storage grooves 7012 are formed in the surface of the storage tray 7011.

[0027] In actual application, the second conveying belt 703 can drive the refractory nozzle to move to the right and approach the storage tray 7011, when the refractory nozzle approaches the storage tray 7011, the refractory nozzle can be moved to the storage groove 7012 formed in the storage tray 7011 by pushing the refractory nozzle for a distance, then the servo motor 708 is controlled to operate, the servo motor 708 drives the rotating rod 709 and the positioning block 7010 to rotate, the positioning block 7010 drives the storage tray 7011 to rotate, so that the storage tray 7011 rotates by an angle, and the storage groove 7012 which does not store the refractory nozzle corresponds to the second conveying belt 703, thereby realizing the effect of automatically demolding and storing the refractory nozzle, when the storage grooves 7012 on the storage tray 7011 are full, the storage tray 7011 can be directly lifted up and taken off, then the storage tray 7011 is placed on the positioning block 7010 again, and the refractory nozzle can be continuously collected and stored.

[0028] As shown in FIGS. Figure 7 , 8As shown in Figure 10, in one embodiment, a connecting seat 8 is installed at the lower end of the second conveyor frame 7, and guide shells 801 are installed at both ends of the connecting seat 8. A slide rod 802 is slidably connected inside the guide shell 801, and a third spring 803 is installed between the slide rod 802 and the guide shell 801. A push block 804 is installed on the circumferential surface of the slide rod 802, and a push rod 805 is installed on the surface of the sliding frame 322. The push rod 805 is slidably connected to the slide rod 802.

[0029] In practical application, when the pusher rod 313 is completely disengaged from the refractory nozzle, the descent of the connecting plate 312 is briefly stopped to provide a position for the first conveyor belt 326 and the second conveyor belt 703 to transport the refractory nozzle, allowing it to move to the end of the second conveyor belt 703 and simultaneously to the opening of the receiving groove 7012. Then, the descent of the connecting plate 312 can continue, causing the sliding frame 322 to slide to the right within the sliding seat 321. During the sliding of the sliding frame 322 to the right, the pusher block 804 can be driven to the right. The pusher 804 moves the slide bar 802 to the right within the guide housing 801, causing the pusher 805 mounted on the slide bar 802 to move to the right. As the pusher 805 moves to the right, it gradually retracts, thus pushing the refractory nozzle located at the end of the second conveyor belt 703 into the storage tank 7012 to complete the storage of the refractory nozzle. When the sliding frame 322 moves to the left, the slide bar 802 is reset by the action of the third spring 803 and moves to both sides to avoid affecting the conveying of the refractory nozzle.

[0030] like Figure 1 , 2 As shown in Figure 17, in one embodiment, the extrusion assembly 2 includes a mounting frame 201, a hydraulic cylinder 202, a connecting block 203, and an extrusion head 204.

[0031] In practical application, the hydraulic cylinder 202 is controlled to operate, which in turn drives the connecting block 203 and the extrusion head 204 to move downward. The extrusion head 204 moves into the extrusion mold 101 to extrude the raw material therein, forming a refractory nozzle. After the extrusion head 204 rises and resets, the demolding component 3 can be controlled to operate, completing the automatic demolding and unloading of the refractory nozzle.
