Description

Technical Field

[0001] The invention relates to the technical field of silica brick processing, and in particular to a silica brick forming machine for a coke oven and a use method thereof. Background Art

[0002] Silica bricks have good resistance to acidic slag erosion, and the load softening temperature is as high as 1640-1670℃. The volume is relatively stable when used for a long time at high temperature. Therefore, according to the characteristics of silica bricks, silica bricks are usually used in the combustion chamber of coke ovens. In the process of preparing silica bricks, a molding vibration molding machine is generally used to mold the silica brick raw materials into bricks.

[0003] The existing Chinese patent is CN202020046402.6, which is a carbon brick vibration forming machine. The first cylinder, the second cylinder and the third cylinder are respectively set to realize the silicon brick molding and the upper demolding activities. However, the vibration trajectory of the silicon bricks in the existing vibration forming machine is mostly up and down vibration activities, which makes the middle part of the silicon brick raw material inside the mold subject to greater force, while the force effect on the side is not sufficient, so that the compaction effect on the side is not obvious enough, and there are phenomena such as uneven brick density, insufficient strength and poor load-bearing performance. At the same time, during the subsequent demolding activities, the friction between the side of the silicon brick and the inner wall of the mold is large, and it is easy to collapse, which affects the quality of silicon brick molding vibration. Summary of the invention

[0012] Preferably, the molding box includes four movable plates that are movable against each other and a limit frame for driving the movable plates to flip. A fixed shaft is arranged between each of the movable plates and the side wall of the working box. A torsion spring for driving the movable plates to reset and rotate is sleeved on the outer side of the fixed shaft, and an auxiliary molding component is arranged in each of the movable plates.

[0013] Preferably, the pushing assembly comprises a hydraulic cylinder fixed on the frame, a piston rod of the hydraulic cylinder is connected to a U-shaped push plate, and the U-shaped push plate slides in the working box.

[0014] Preferably, a connecting plate is fixedly provided on the U-shaped push plate, and one end of the connecting plate away from the U-shaped push plate is fixedly connected to the limit frame, and the limit frame slides on the movable plate.

[0015] Preferably, the auxiliary forming assembly includes a plurality of rotating shafts rotatably connected to the movable plate, a transmission member is arranged between two adjacent rotating shafts, a driving motor for driving one of the rotating shafts to rotate is fixedly arranged in the movable plate, each of the rotating shafts is connected to a curved rod, a collar is sleeved on the curved rod, a connecting rod is connected to the collar, an end of the connecting rod away from the collar is connected to an extrusion plate slidably connected to the movable plate, and the extrusion plates on two adjacent movable plates are staggered.

[0016] Preferably, the transmission member comprises synchronous wheels respectively fixed on two adjacent rotating shafts, and a synchronous belt is arranged between the two synchronous wheels.

[0017] Preferably, the pushing assembly and the vibration motor work simultaneously, and the pushing assembly and the auxiliary molding assembly work alternately and intermittently.

[0018] Preferably, an L-shaped rod is fixed on the limit frame, a rack plate is provided on the L-shaped rod, a rotating rod is rotatably connected to the middle part of the material box, a one-way gear meshing with the rack plate is provided on the rotating rod, and a spiral conveying blade for conveying silicon brick raw materials is provided on the lower side of the rotating rod.

[0019] Preferably, a partition is slidably connected inside the working box, an elastic rope is provided between the partition and the limit frame, a support plate that movably resists the partition is fixedly provided on the outside of the material box, a guide rod is provided on the support plate, and the elastic rope is slidably connected to the guide rod.

[0020] The invention also discloses a method for using a coke oven silica brick forming machine, comprising the following steps:

[0021] S1: Place the silica brick raw materials in the material box to prepare for silica brick extrusion molding;

[0022] S2: Then the hydraulic cylinder is controlled to operate, and the piston rod of the hydraulic cylinder pushes the U-shaped push plate to move in the working box. When the U-shaped push plate moves, the limit frame is driven to move through the connecting plate, and the limit frame moves from the working box to the forming box;

[0023] S3: When the U-shaped push plate moves, it drives the L-shaped rod to move. The rack plate on the L-shaped rod meshes with the one-way gear on the rotating rod. The one-way gear drives the rotating rod and the spiral conveying blade on the rotating rod to rotate. The spiral conveying blade transports the silicon brick raw materials in the material box downward and drops into the working box through the feed port. As the U-shaped push plate moves in the working box, the U-shaped push plate blocks the feed port, and at this time the rack plate is no longer meshed with the one-way gear.

[0024] S4: When the limiting frame moves from the working box to the forming box, the limiting frame presses against the movable plate, and the four movable plates rotate and approach each other until the four movable plates surround and form a forming cavity, and the inner wall of one end of the enclosed forming cavity abuts against the vibration plate;

[0025] When the limit frame moves, the partition is pulled by the elastic rope, and the partition is lifted up by the force until it abuts against the support plate. As the limit frame continues to move, the elastic rope is stretched and deformed;

[0026] S5: Since one end of the forming box is blocked by the vibration plate, the silicon brick raw material is squeezed when the U-shaped push plate moves along the working box, and the vibration motor drives the vibration plate to vibrate, thereby realizing the extrusion vibration molding of the silicon brick raw material;

[0027] S6: When the silicon brick raw material is extruded and formed, the pushing assembly and the driving motor are controlled to work alternately. After the pushing assembly cooperates with the vibration plate to extrude the silicon brick raw material once, the pushing assembly is stopped and the driving motor is controlled to operate. When the driving motor is in operation, one of the rotating shafts is driven to rotate, and the rotating shaft drives another rotating shaft to rotate through a transmission member. When each rotating shaft rotates, the sleeve ring is driven to move through a crankshaft, and the sleeve ring drives the extrusion plate to slide on the movable plate through a connecting rod, so that each movable plate extrude the silicon brick raw material sideways through the extrusion plate, thereby realizing lateral vibration compaction of the silicon brick until the silicon brick is finally formed;

[0028] S7: Control the hydraulic cylinder to reset, and no longer control the drive motor to run. The hydraulic cylinder drives the U-shaped push plate to reset and move back. The U-shaped push plate drives the limit frame to move back through the connecting plate, so that the limit frame moves to the working box. The limit frame no longer abuts against the movable plate. The movable plate resets and flips under the action of the torsion spring, so that the multiple inner walls of the forming box no longer abut against the formed silicon bricks. The formed silicon bricks slide down along the movable plate at the bottom of the forming box to be discharged;

[0029] S8: Repeat S2-S7 to achieve continuous extrusion molding of silica bricks.

[0030] Compared with the prior art, the present invention provides a coke oven silica brick forming machine and a method of using the same, which have the following beneficial effects:

[0031] 1. The silicon brick forming machine for coke oven and the method for using the same, through the pushing component in cooperation with the vibration plate to centrally extrude the middle of the silicon brick raw material, and in cooperation with the auxiliary forming component to extrude the side of the silicon brick raw material, so that the silicon brick raw material is evenly stressed everywhere, and the density uniformity and strength of the silicon brick after forming are improved. Moreover, the movable plates of the forming box are automatically separated, and the silicon brick is quickly unloaded after forming, so that the silicon brick no longer abuts against the inner wall of the forming box, and the problem of the silicon brick abutting against the inner wall of the mold when the silicon brick is discharged in the prior art is solved, so that the side of the silicon brick is damaged, thereby improving the processing efficiency and processing quality of the silicon brick.

[0032] 2. The silicon brick forming machine for coke oven and the method for using the same drive the L-shaped rod to move when the U-shaped push plate moves. The rack plate on the L-shaped rod meshes with the one-way gear on the rotating rod for transmission. The one-way gear drives the rotating rod and the spiral conveying blade on the rotating rod to rotate. The spiral conveying blade conveys the silicon brick raw materials in the material box downward and drops them into the working box through the feed port, which is convenient for loading a quantitative amount of silicon brick raw materials. The efficiency is high and the feeding amount is easy to control, avoiding blockage and uneven feeding when the silicon brick raw materials fall from the material box to the working box, ensuring that the amount of silicon brick raw materials extruded each time is basically the same, thereby ensuring the quality of silicon brick production.

[0033] 3. The silicon brick forming machine for coke oven and the method for using the same, by arranging a partition in the working box, prevents the silicon brick raw materials falling from the material box into the working box from splashing and overflowing on a large scale, which would pollute the working environment. After the limit frame moves, it can abut against the movable plate, and after the movable plate is turned over, it abuts against the vibration plate, and the vibration plate blocks one end of the forming box. At this time, as the limit frame moves, the partition continues to move upward, so that the partition does not hinder the pushing action of the U-shaped push plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0047] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0048] Example 1: Reference Figure 1-8 , a silicon brick forming machine for coke oven, comprising a frame 1, and also comprising:

[0049] A working box 2, which is fixed on the frame 1, and both ends of the working box 2 are provided with openings 201;

[0050] A material box 3, which is fixed on the top of the working box 2 and is used to store silicon brick raw materials. A material inlet 202 connected to the material box 3 is provided on the top of the working box 2;

[0051] A pushing assembly, which is disposed on one side of the working box 2 and is used to push and squeeze the silicon brick raw materials in the working box 2; and

[0052] The forming box 4 is arranged at one end of the working box 2 away from the pushing assembly, and is used for extrusion forming of silicon brick raw materials and automatic unloading of silicon bricks after extrusion forming;

[0053] An elastic telescopic rod 5 is fixedly provided on one side of the frame 1 away from the pushing assembly, and a vibration plate 501 that movably contacts the inner wall of the forming box 4 is fixedly provided at the end of the elastic telescopic rod 5 , and a vibration motor 502 is provided on the vibration plate 501 .

[0054] Furthermore, the forming box 4 includes four movable plates 401 that are movable against each other and a limit frame 402 for driving the movable plates 401 to flip. A fixed shaft 4011 is arranged between each movable plate 401 and the side wall of the working box 2. A torsion spring 4012 is sleeved on the outer side of the fixed shaft 4011 for driving the movable plate 401 to reset and rotate, and an auxiliary forming component is arranged in each movable plate 401.

[0055] Specifically, the silicon brick raw material is placed in the material box 3 to prepare for the extrusion molding of the silicon bricks. The pushing component and the vibration motor 502 are controlled to operate. The vibration motor 502 drives the vibration plate 501 to vibrate. The pushing component cooperates with the vibration plate 501 to concentrate on squeezing the middle of the silicon brick raw material, and cooperates with the auxiliary molding component to squeeze the side of the silicon brick raw material, so that the silicon brick raw material is evenly stressed everywhere, and the density uniformity and strength of the silicon brick after molding are improved. After the silicon brick raw material is extruded and molded, the various movable plates 401 of the molding box 4 are automatically separated, and the silicon bricks are quickly unloaded after being formed, so that the silicon bricks are no longer in contact with the inner wall of the molding box 4, thereby solving the problem in the prior art that the silicon bricks are damaged by the contact with the inner wall of the mold when the silicon bricks are discharged, thereby improving the processing efficiency and processing quality of the silicon bricks.

[0056] Example 2: Reference Figure 1-8 A silicon brick forming machine for coke oven, based on Example 1, further, the pushing assembly includes a hydraulic cylinder 6 fixed on the frame 1, the piston rod of the hydraulic cylinder 6 is connected to a U-shaped push plate 601, and the U-shaped push plate 601 slides in the working box 2.

[0057] Furthermore, a connecting plate 602 is fixedly provided on the U-shaped push plate 601 , and one end of the connecting plate 602 away from the U-shaped push plate 601 is fixedly connected to the limiting frame 402 , and the limiting frame 402 slides on the movable plate 401 .

[0058] Specifically, the hydraulic cylinder 6 is controlled to operate, and the piston rod of the hydraulic cylinder 6 pushes the U-shaped push plate 601 to move in the working box 2. When the U-shaped push plate 601 moves, it drives the limit frame 402 to move through the connecting plate 602. The limit frame 402 moves from the working box 2 to the molding box 4. When the limit frame 402 moves to the molding box 4, the limit frame 402 abuts against each movable plate 401 of the molding box 4, so that the movable plate 401 is flipped under force, and the movable plates 401 of the molding box 4 abut against each other to form a molding cavity.

[0059] Example 3: Reference Figure 1 , Figure 2 , Fig. 9 , Fig.10 and Fig.11 , a silicon brick forming machine for coke oven, based on Example 2, further, the auxiliary forming component includes a plurality of rotating shafts 7 rotatably connected to the movable plate 401, a transmission member is arranged between two adjacent rotating shafts 7, a driving motor 701 for driving one of the rotating shafts 7 to rotate is fixedly arranged in the movable plate 401, each rotating shaft 7 is connected to a bent rod 702, a collar 703 is sleeved on the bent rod 702, a connecting rod 704 is connected to the collar 703, an end of the connecting rod 704 away from the collar 703 is connected to an extrusion plate 705 slidably connected to the movable plate 401, and the extrusion plates 705 on two adjacent movable plates 401 are staggered.

[0060] Furthermore, the transmission member includes synchronous wheels 8 respectively fixed on two adjacent rotating shafts 7 , and a synchronous belt 801 is arranged between the two synchronous wheels 8 .

[0061] Specifically, when the driving motor 701 is running, it drives one of the rotating shafts 7 to rotate, and the rotating shaft 7 drives the other rotating shaft 7 to rotate through the transmission member. When each rotating shaft 7 rotates, it drives the ring 703 to move through the curved rod 702, and the ring 703 drives the extrusion plate 705 to slide on the movable plate 401 through the connecting rod 704, so that each movable plate 401 can squeeze the side of the silicon brick raw material through the extrusion plate 705 to achieve lateral vibration of the silicon brick, which solves the problem that the vibration trajectory of the silicon brick in the prior art is mostly up and down vibration, so that the middle part of the silicon brick raw material inside the mold is subjected to greater force, while the force effect on the side is less sufficient.

[0062] Example 4: Reference Figure 1-8 , a silicon brick forming machine for coke oven, based on Example 3, further, the pushing component and the vibration motor 502 work simultaneously, and the pushing component and the auxiliary forming component work alternately and intermittently.

[0063] Specifically, the pushing assembly and the vibration motor 502 work simultaneously to realize the extrusion and vibration molding of the silicon brick raw material. By controlling the pushing assembly and the driving motor 701 to work alternately, after the pushing assembly cooperates with the vibration plate 501 to extrude the silicon brick raw material once, the pushing assembly stops working and the auxiliary molding assembly is controlled to work, so as to avoid the U-shaped pushing plate 601 pushing the silicon brick raw material to the right when the pushing assembly and the auxiliary molding assembly work simultaneously, and the extrusion plate 705 moved out of the movable plate 401 hinders the rightward extrusion molding work on the side of the silicon brick raw material, resulting in a wider dent on the side of the silicon brick raw material as it is pushed to the right, affecting the subsequent extrusion molding effect of the silicon brick.

[0064] Example 5: Reference Figure 1-6 A silicon brick forming machine for coke oven, based on Example 4, further, an L-shaped rod 9 is fixedly provided on the limit frame 402, a rack plate 901 is provided on the L-shaped rod 9, a rotating rod 10 is rotatably connected to the middle part of the material box 3, a one-way gear 1001 meshing with the rack plate 901 is provided on the rotating rod 10, and a spiral conveying blade 1002 for conveying silicon brick raw materials is provided on the lower side of the rotating rod 10.

[0065] Specifically, when the pushing assembly works, the U-shaped push plate 601 moves and drives the L-shaped rod 9 to move. The rack plate 901 on the L-shaped rod 9 meshes with the one-way gear 1001 on the rotating rod 10 for transmission. The one-way gear 1001 drives the rotating rod 10 and the spiral conveying blade 1002 on the rotating rod 10 to rotate. The spiral conveying blade 1002 conveys the silicon brick raw material in the material box 3 downward and drops it into the working box 2 through the feed port 202. As the U-shaped push plate 601 moves in the working box 2, the U-shaped push plate 601 blocks the feed port 202. , and at this time the rack plate 901 is no longer meshed with the one-way gear 1001, and when the rack plate 901 is reset and moved back, the one-way gear 1001 will not drive the rotating rod 10 and the spiral conveying blade 1002 on the rotating rod 10 to rotate in the opposite direction. The present application is convenient for feeding a quantitative amount of silicon brick raw materials, with high efficiency and easy control of the feeding amount, avoiding blockage and uneven feeding when the silicon brick raw materials fall from the material box 3 to the working box 2, ensuring that the amount of silicon brick raw materials extruded each time is basically the same, thereby ensuring the quality and uniformity of silicon brick production.

[0066] Example 6: Reference Figure 1-6 A silicon brick forming machine for coke oven, based on Example 5, further, a partition 11 is slidably connected in the working box 2, an elastic rope 111 is arranged between the partition 11 and the limit frame 402, a support plate 12 which is movably opposed to the partition 11 is fixedly arranged on the outside of the material box 3, a guide rod 121 is arranged on the support plate 12, and the elastic rope 111 is slidably connected to the guide rod 121.

[0067] Specifically, a partition 11 is provided in the working box 2 to prevent the silicon brick raw materials falling from the material box 3 into the working box 2 from splashing and overflowing on a large scale, which would pollute the working environment. When the limit frame 402 moves, the partition 11 is driven to gradually move upward by the elastic rope 111. After the limit frame 402 abuts against the movable plate 401, the movable plate 401 flips over and abuts against the vibration plate 501. The vibration plate 501 blocks one end of the forming box 4. At this time, as the limit frame 402 moves, the partition 11 continues to move upward, so that the partition 11 does not hinder the pushing action of the U-shaped push plate 601.

[0068] The invention also discloses a method for using a coke oven silica brick forming machine, comprising the following steps:

[0069] S1: placing silicon brick raw materials in a material box 3 to prepare for silicon brick extrusion molding;

[0070] S2: Then the hydraulic cylinder 6 is controlled to operate, and the piston rod of the hydraulic cylinder 6 pushes the U-shaped push plate 601 to move in the working box 2. When the U-shaped push plate 601 moves, it drives the limit frame 402 to move through the connecting plate 602, and the limit frame 402 moves from the working box 2 to the forming box 4;

[0071] S3: When the U-shaped push plate 601 moves, it drives the L-shaped rod 9 to move, and the rack plate 901 on the L-shaped rod 9 meshes with the one-way gear 1001 on the rotating rod 10 for transmission. The one-way gear 1001 drives the rotating rod 10 and the spiral conveying blade 1002 on the rotating rod 10 to rotate. The spiral conveying blade 1002 conveys the silicon brick raw materials in the material box 3 downward and drops into the working box 2 through the feed port 202. As the U-shaped push plate 601 moves in the working box 2, the U-shaped push plate 601 blocks the feed port 202, and at this time, the rack plate 901 is no longer meshed with the one-way gear 1001;

[0072] S4: When the limiting frame 402 moves from the working box 2 to the forming box 4, the limiting frame 402 presses the movable plate 401, and the four movable plates 401 rotate and approach each other until the four movable plates 401 surround and form a forming cavity, and the inner wall of one end of the enclosed forming cavity abuts against the vibration plate 501;

[0073] When the limit frame 402 moves, the partition 11 is pulled by the elastic rope 111, and the partition 11 is lifted up by the force until it abuts against the support plate 12. As the limit frame 402 continues to move, the elastic rope 111 is stretched and deformed;

[0074] S5: Since one end of the forming box 4 is blocked by the vibration plate 501, the U-shaped push plate 601 squeezes the silicon brick raw material when it moves along the working box 2, and the vibration motor 502 drives the vibration plate 501 to vibrate, thereby realizing the extrusion vibration molding of the silicon brick raw material;

[0075] S6: When the silicon brick raw material is extruded and formed, the pushing assembly and the driving motor 701 are controlled to work alternately. After the pushing assembly cooperates with the vibration plate 501 to extrude the silicon brick raw material once, the pushing assembly is stopped and the driving motor 701 is controlled to run. When the driving motor 701 is running, it drives one of the rotating shafts 7 to rotate, and the rotating shaft 7 drives another rotating shaft 7 to rotate through a transmission member. When each rotating shaft 7 rotates, the collar 703 is driven to move through the bent rod 702, and the collar 703 drives the extrusion plate 705 to slide on the movable plate 401 through the connecting rod 704, so that each movable plate 401 can extrude the silicon brick raw material sideways through the extrusion plate 705, so as to realize the lateral vibration of the silicon brick, until the silicon brick is finally formed;

[0076] S7: Control the hydraulic cylinder 6 to reset, and no longer control the driving motor 701 to run. The hydraulic cylinder 6 drives the U-shaped push plate 601 to reset and move back. The U-shaped push plate 601 drives the limit frame 402 to move back through the connecting plate 602, so that the limit frame 402 moves to the working box 2. The limit frame 402 no longer abuts against the movable plate 401. The movable plate 401 resets and flips under the action of the torsion spring 4012, so that the multiple inner walls of the forming box 4 no longer abut against the formed silicon bricks. The formed silicon bricks slide down along the movable plate 401 at the bottom of the forming box 4 to be discharged;

[0077] S8: Repeat S2-S7 to achieve continuous extrusion molding of silica bricks.

[0078] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

6. A method for using the silica brick forming machine for coke oven according to claim 5, characterized in that: The following steps are involved: S1: placing silicon brick raw materials in a material box (3) to prepare for silicon brick extrusion molding; S2: Then, the hydraulic cylinder (6) is controlled to operate, and the piston rod of the hydraulic cylinder (6) pushes the U-shaped push plate (601) to move in the working box (2). When the U-shaped push plate (601) moves, it drives the limit frame (402) to move through the connecting plate (602), and the limit frame (402) moves from the working box (2) to the forming box (4); S3: When the U-shaped push plate (601) moves, it drives the L-shaped rod (9) to move. The rack plate (901) on the L-shaped rod (9) meshes with the one-way gear (1001) on the rotating rod (10) for transmission. The one-way gear (1001) drives the rotating rod (10) and the spiral conveying blade (1002) on the rotating rod (10) to rotate. The spiral conveying blade (1002) conveys the silicon brick raw material in the material box (3) downward and drops it into the working box (2) through the feed port (202). As the U-shaped push plate (601) moves in the working box (2), the U-shaped push plate (601) blocks the feed port (202), and at this time, the rack plate (901) is no longer meshed with the one-way gear (1001); S4: when the limiting frame (402) moves from the working box (2) to the forming box (4), the limiting frame (402) presses against the movable plate (401), and the four movable plates (401) rotate and move closer to each other until the four movable plates (401) surround and form a forming cavity, and the inner wall of one end of the enclosed forming cavity contacts the vibration plate (501); When the limit frame (402) moves, the partition (11) is pulled by the elastic rope (111), and the partition (11) is lifted up by the force until it abuts against the support plate (12). As the limit frame (402) continues to move, the elastic rope (111) is stretched and deformed; S5: Since one end of the forming box (4) is blocked by the vibration plate (501), the silicon brick raw material is squeezed when the U-shaped push plate (601) moves along the working box (2), and the vibration motor (502) drives the vibration plate (501) to vibrate, thereby achieving extrusion vibration molding of the silicon brick raw material; S6: When the silicon brick raw material is extruded and formed, the pushing component and the driving motor (701) are controlled to work alternately. After the pushing component cooperates with the vibration plate (501) to extrude the silicon brick raw material once, the pushing component stops working and the driving motor (701) is controlled to operate. When the driving motor (701) operates, it drives one of the rotating shafts (7) to rotate. The rotating shaft (7) drives another rotating shaft (7) to rotate through a transmission member. When each rotating shaft (7) rotates, it drives the collar (703) to move through the bent rod (702). The collar (703) drives the extrusion plate (705) to slide on the movable plate (401) through the connecting rod (704), so that each movable plate (401) can extrude the silicon brick raw material on the side through the extrusion plate (705), thereby realizing lateral vibration compaction of the silicon brick until the silicon brick is finally formed; S7: Controlling the hydraulic cylinder (6) to reset, and no longer controlling the driving motor (701) to run, the hydraulic cylinder (6) drives the U-shaped push plate (601) to reset and move back, the U-shaped push plate (601) drives the limit frame (402) to move back through the connecting plate (602), so that the limit frame (402) moves to the working box (2), the limit frame (402) no longer abuts against the movable plate (401), the movable plate (401) resets and flips under the action of the torsion spring (4012), so that the multiple inner walls of the molding box (4) no longer abut against the molded silicon bricks, and the molded silicon bricks slide down along the movable plate (401) at the bottom of the molding box (4) to be discharged; S8: Repeat S2-S7 to achieve continuous extrusion molding of silica bricks.
