Description

Technical Field

[0001] The present invention relates to the technical field of die-casting equipment, and particularly to a die-casting device for refractory material production. Background Art

[0002] Refractory materials are applied in fields such as iron and steel, non-ferrous metals, glass, cement, ceramics, petrochemicals, machinery, boilers, light industry, and electric power. During production and processing, die-casting methods are mostly used to complete the process. When pressing into shape, the raw materials are first fed into the mold through a feeding mechanism, and the upper mold is pressed down by a hydraulic cylinder to achieve the effect of stamping and forming.

[0003] According to a disclosed die-casting device for refractory material production (Publication No.: CN218192485U), in the above application, a scraping mechanism can be used to clean the surface of the base, and at the same time, it can level the raw materials after the feeding mechanism has fed the raw materials. The brush on the movable block can be used to clean the inner wall of the cavity, thus solving the problem that the die-casting refractory brick device in the prior art cannot clean the mold in time during use.

[0004] However, during the actual use of the above device, when the scraper moves back and forth on the upper surface of the lower mold, residues of refractory materials may adhere to both sides of the scraper. This causes the residues attached to the back of the scraper to possibly fall off due to mechanical vibration or other reasons on the way back after the scraper has scraped once, and then reattach to the cavity or the push plate at the bottom of the cavity, thereby affecting the next die-casting operation of refractory materials. In view of this, we propose a die-casting device for refractory material production. Summary of the Invention

[0016] Compared with the prior art, the present invention provides a die-casting device for refractory material production, which has the following beneficial effects:

[0017] 1. For the die-casting device for refractory material production, through the arrangement of the horizontally "h"-shaped guiding groove and the guiding column, and in cooperation with the driving of the large gear by the tooth pattern with a length equal to half of the circumference of the large gear on the lower part of the guiding plate, when the threaded plate drives the square rod, the sleeve and the large gear close to the guiding plate, through the guiding of the above-mentioned tooth pattern, the large gear is driven to rotate 180°, so as to realize the replacement of the main scraper directly below the sleeve with another group of main scrapers directly above the sleeve, and then realize the replacement of the scraper for cleaning the surface of the base and the push plate as the threaded plate moves in the reverse direction and resets, avoiding the residue of the scraper from being scattered on the surface of the base or the push plate as the threaded plate moves in the reverse direction, which will affect the subsequent die-casting operation of refractory material bricks.

[0018] 2. For the die-casting device for refractory material production, by providing a self-cleaning component, when the main scraper and the auxiliary scraper gradually approach the cleaning inclined plate as the square column moves, due to the inclined surface setting of the cleaning inclined plate, the main scraper and the auxiliary scraper that can deflect by a certain amplitude with the fixed column as the rotation center have a tendency to push the cleaning inclined plate to both sides during the movement. At this time, in cooperation with the setting of the connecting spring, the cleaning inclined plate is tightly attached to the side walls of the main scraper and the auxiliary scraper, so as to scrape and clean the residues on their surfaces, thus ensuring that no secondary pollution will occur during the subsequent cleaning operation and improving the overall production efficiency of the device.

[0019] 3. For the die-casting device for refractory material production, by providing a scraping component, during the reset movement of the threaded plate, due to the relative movement of the guiding column and the guiding groove, the guiding plate will drive the toothed plate to move upward. At this time, in cooperation with the small gear, the L-shaped plate drives the supporting plate to move downward, and then cooperates with the connecting piece to drive the cleaning inclined plate to move downward relative to the cleaning block, so that the saw-tooth strip and the serrated belt at the bottom of the auxiliary cleaning cavity can clean the solid impurities on the surface of the cleaning inclined plate and discharge them smoothly, rather than accumulating near the cleaning inclined plate, which will affect the subsequent cleaning effect of the cleaning inclined plate on the main scraper and the auxiliary scraper, so as to ensure the stable operation of the device.

[0020] 4. The die-casting device for producing refractory materials is provided with a swing-back component. During the movement of the threaded plate, due to the contact balls provided on the outer wall of the end of the square rod and the wavy setting in the middle section of the guiding groove, the square rod makes small reciprocating movements left and right while sliding along the connecting column. In cooperation with the connecting block and the rectangular grooves provided on the arc-shaped outer wall of the sleeve, the square column, the main scraper, and the auxiliary scraper are driven to make reciprocating movements left and right along the outer surface of the sleeve, thereby improving the cleaning effect of the main scraper and the auxiliary scraper on the upper surfaces of the base and the push plate, and ensuring the normal development of the subsequent production work of the device.

Detailed implementation manner

[0033] As Figures 1-11 shown, the present invention provides a technical solution: a die-casting device for refractory material production, including a workbench 1, the upper surface of the workbench 1 is fixedly installed with a top plate 2 through a column, the upper surface of the top plate 2 is fixedly installed with a hydraulic device 3, the output end of the hydraulic device 3 penetrates through the top plate 2 and is fixedly connected with a pressing block 4, the upper surface of the workbench 1 is fixedly installed with a base 5, a cavity 6 is opened in the inner wall of the base 5, the lower surface of the workbench 1 is fixedly installed with a thruster 7, the output end of the thruster 7 penetrates through the workbench 1 and is fixedly installed with a push plate 8, and a cleaning assembly 9 for scraping and cleaning the refractory material bricks in the cavity 6 and the surface of the lifted push plate 8 is arranged on the upper surface of the workbench 1. The cleaning assembly 9 includes a mounting plate 91, a driving motor 92, a threaded rod 93, a threaded plate 94, a square rod 95, a sleeve 96, a main scraper 97, a large gear 98, a telescopic rod 99, a guide plate 910, a return spring 911, a guide groove 912, a guide post 913, a rotating rod 914, a stop bar 915 and a coil spring 916.

[0034] In an embodiment of the present invention, a mounting plate 91 is fixedly installed on the upper surface of the workbench 1. A driving motor 92 is fixedly installed on the outer wall of the mounting plate 91 on the side away from the center of the workbench 1. The output end of the driving motor 92 is fixedly installed with a threaded rod 93. A threaded plate 94 is threadedly connected to the outer wall of the threaded rod 93. A square rod 95 is inserted through and slidably installed in the inner wall of the threaded plate 94. A sleeve 96 is sleeved on the outer wall of the square rod 95. A main scraper 97 is arranged on the outer surface of the sleeve 96. A large gear 98 is inserted through and fixedly installed on the sleeve 96. The lower surface of the outer wall of the mounting plate 91 close to the base 5 is fixedly connected to the top end of a telescopic rod 99. The bottom end of the telescopic rod 99 is fixedly connected to a guide plate 910. A return spring 911 is sleeved on the outer wall of the telescopic rod 99. A guide groove 912 is formed on the outer wall of the guide plate 910 away from the base 5. A guide post 913 is fixedly installed on the outer wall of the threaded plate 94 close to the guide plate 910. A rotating rod 914 is fixedly installed on the inner wall of the guide groove 912. A stop rod 915 is inserted through and rotatably installed on the rotating rod 914. A coil spring 916 is sleeved on the outer wall of the rotating rod 914.

[0035] Specifically, a protruding portion adapted to the size of the cavity 6 is provided on the lower surface of the pressing block 4, and this protruding portion and the cavity 6 are arranged on the same vertical line. So that during the process of the pressing block 4 moving downward driven by the hydraulic device 3, the protruding portion on the lower surface of the pressing block 4 can just be inserted into the cavity 6 to perform die-casting operation on the refractory brick in the cavity 6. At the same time, the pusher 7 is arranged directly below the workbench 1, and the push plate 8 is arranged at the bottom of the cavity 6. Specifically, the size of the push plate 8 is adapted to the cavity 6. Thus, in the initial state, the bottom surface of the push plate 8 is in contact with the upper surface of the workbench 1. After the die-casting operation of the refractory brick is completed, by starting the pusher 7, the push plate 8 is pushed upward from the bottom space of the cavity 6 until the refractory brick extends out of the cavity 6 and is above the base 5, which is convenient for the staff to take out. Specifically, the pusher 7 can adopt a linear motor or a hydraulic cylinder to ensure that the push plate 8 has sufficient upward pushing force. In addition, when the push plate 8 is pushed upward, it moves at most until its upper surface is flush with the upper surface of the base 5, which is convenient for subsequent cleaning work.

[0036] Please refer to the attached drawings in the specification Figures 2-8, in the embodiment of the present invention, the number of mounting plates 91 is set to two groups, and the two groups of mounting plates 91 are mirror - arranged on the left and right sides of the vertical central axis of the base 5. Moreover, a gap is provided between the mounting plate 91 and the base 5 to leave enough space for the sleeve 96 to drive the main scraper 97 to rotate without being affected by other components. At the same time, the number of driving motors 92 is set to two groups, and the two groups of driving motors 92 are symmetrically arranged with the vertical central axis of the mounting plate 91 as the axis of symmetry. Thus, in cooperation with the threaded rods 93 and the threaded plates 94 corresponding to the two groups of driving motors 92, the sleeve 96 and the main scraper 97 can stably scrape and clean the upper surface of the base 5 and the upper surface of the push plate 8 pushed out from the cavity 6. In addition, the end cross - section of the square rod 95 is square, and a circular hole with a diameter adapted to the side length of the end cross - section of the square rod 95 is provided on the inner wall of the threaded plate 94. Furthermore, the square rod 95 can slide left and right relative to the circular hole without being affected by movement interference without affecting the relative rotation of the square rod 95 relative to the threaded plate 94. Further, a square cavity adapted to the square rod 95 is provided on the inner wall of the sleeve 96, and the square rod 95 is arranged inside the square cavity so that the square rod 95 can have a relative displacement in the horizontal direction with the sleeve 96 without relative rotation. Specifically, the square rod 95 and the sleeve 96 always rotate in the same direction and at the same speed. At the same time, the side wall of the threaded plate 94 is rotatably connected to the end of the sleeve 96, thereby ensuring the stability of the movement of the sleeve 96.

[0037] Further, two sets of main scraping plates 97 are provided, and the two sets of main scraping plates 97 are mirror - arranged on both sides of the outer wall of the sleeve 96. At the same time, the lower surface of the guide plate 910 is provided with tooth patterns that mesh with the large gear 98 to achieve transmission, and the length of the tooth patterns is the same as half of the circumference of the large gear 98. Thus, when the threaded plate 94 drives the square rod 95, the sleeve 96, and the large gear 98 close to the guide plate 910, through the guidance of the above - mentioned tooth patterns, the large gear 98 is driven to rotate 180°, so as to realize the replacement of the main scraping plate 97 directly below the sleeve 96 with another set of main scraping plates 97 above the sleeve 96. Furthermore, as the threaded plate 94 moves in the reverse direction and resets, the scraping plate for cleaning the surface of the base 5 and the push plate 8 is replaced, avoiding the residue of the scraping plate from being scattered on the surface of the base 5 or the push plate 8 as the threaded plate 94 moves in the reverse direction, which may affect the subsequent die - casting operation of refractory bricks. Specifically, the guide groove 912 is arranged in a horizontal "h" shape. Specifically, the guide groove 912 includes an upper groove and a lower groove, and the upper groove and the lower groove are connected by an inclined groove. In addition, the rotating rod 914, the coil spring 916, and the blocking rod 915 are arranged at the connection of the inclined groove and the upper groove, and both ends of the coil spring 916 are fixedly connected to the arc - shaped outer wall of the rotating rod 914 and the side wall of the blocking rod 915 respectively. At the same time, in the initial state, the coil spring 916 always has a tendency to drive the blocking rod 915 to deflect towards the top side of the upper groove. Thus, when the threaded plate 94 approaches the guide plate 910, the guide post 913 arranged on the side of the threaded plate 94 is flush with the upper groove of the guide groove 912 and enters the upper groove until it reaches the top of the upper groove. During this process, when the guide post 913 contacts the blocking rod 915, the blocking rod 915 will deflect towards the lower groove side with the rotating rod 914 as the rotation center and will not block the normal movement of the guide post 913. When the threaded plate 94 moves in the reverse direction for reset, when the guide post 913 moves to the connection of the upper groove and the inclined groove, it is blocked by the blocking rod 915 and enters the inclined groove, and finally enters the lower groove. At this time, due to the height limitation of the guide post 913, the guide plate 910 moves upward with the telescopic rod 99, so that the tooth patterns arranged below the guide plate 910 will not affect the large gear 98 during the reverse movement of the threaded plate 94, thereby ensuring the relative stability of the main scraping plate 97 during the reset scraping and cleaning movement.

[0038] In addition, please refer to the attached Figures 7-9, in an embodiment of the present invention, a self-cleaning component 10 for cleaning the surface of the main scraper 97 is provided above the base 5. The self-cleaning component 10 includes a square column 101. The square column 101 is sleeved on the arc-shaped outer wall of the sleeve 96. A connecting block 102 is fixedly connected between the outer wall of the square rod 95 and the inner wall of the square column 101. A fixing column 103 is fixedly installed on the upper surface of the square column 101. The outer wall of the fixing column 103 is rotatably connected to the main scraper 97. A secondary scraper 104 is rotatably connected to the outer wall of the fixing column 103. A first scroll spring 105 and a second scroll spring 106 are sleeved on the outer wall of the fixing column 103. A convex ball 107 is fixedly installed on the outer wall of the main scraper 97 near the square column 101. An arc-shaped groove 108 is formed on the outer wall of the square column 101. An installation seat 109 is fixedly installed on the side wall of the base 5. A cleaning block 1011 is slidably installed in the inner wall of the installation seat 109. A telescopic member 1010 is fixedly connected between the side wall of the cleaning block 1011 and the inner wall of the installation seat 109. A connecting spring 1012 is sleeved on the outer wall of the telescopic member 1010. A cleaning inclined plate 1013 is arranged inside the cleaning block 1011.

[0039] Specifically, a cylindrical cavity adapted to the outer diameter of the sleeve 96 is formed at the center of the square column 101, and the sleeve 96 is arranged inside the cylindrical cavity. In addition, a rectangular groove adapted to the size of the connecting block 102 is formed on the arc-shaped inner wall of the sleeve 96, and the connecting block 102 is arranged inside the rectangular groove. Thus, the square rod 95 can drive the square column 101 to move horizontally on the outer surface of the sleeve 96 through the connecting block 102. Specifically, the main scraper 97 and the secondary scraper 104 are hinged through the fixing column 103. Circular grooves are formed on the inner walls of the mutually approaching ends of the main scraper 97 and the secondary scraper 104 to facilitate the arrangement of the first scroll spring 105 and the second scroll spring 106. Further, the two ends of the first scroll spring 105 are respectively fixedly connected to the arc-shaped outer wall of the fixing column 103 and the inner wall of the circular groove formed at the end of the main scraper 97. At the same time, the two ends of the second scroll spring 106 are respectively fixedly connected to the arc-shaped outer wall of the fixing column 103 and the inner wall of the circular groove formed at the end of the secondary scraper 104. Therefore, while the main scraper 97 and the secondary scraper 104 can rotate around the fixing column 103 as the rotation center, they are respectively affected by the elastic forces of the first scroll spring 105 and the second scroll spring 106 and always have a movement tendency of reverse rotation to achieve reset. Specifically, the main scraper 97 and the secondary scraper 104 are in the same plane in the initial state, and the directions of the main scraper 97 and the secondary scraper 104 are parallel to the axis direction of the sleeve 96. Further, the convex ball 107 is arranged inside the arc-shaped groove 108 to limit the deflection angle of the main scraper 97 and the secondary scraper 104 on the outer wall of the square column 101 to prevent their deflection angles from being too large and affecting the normal discharging work in the cavity 6.

[0040] Meanwhile, the connecting spring 1012 is sleeved outside the telescopic member 1010, and both ends of the connecting spring 1012 are fixedly connected to the inner wall end of the mounting seat 109 and the side wall of the cleaning block 1011 respectively. In addition, the end cross-section of the cleaning inclined plate 1013 is set as a right trapezoid, and the inclined surface of the cleaning inclined plate 1013 faces the base 5 side. Specifically, the number of the cleaning inclined plates 1013, the cleaning blocks 1011, the telescopic members 1010 and the connecting springs 1012 is set to two groups, and the two groups of cleaning inclined plates 1013, cleaning blocks 1011, telescopic members 1010 and connecting springs 1012 are symmetrically arranged with the vertical central axis of the mounting seat 109 as the axis of symmetry. Thus, when the main scraper 97 and the secondary scraper 104 gradually approach the cleaning inclined plate 1013 as the square column 101 moves, due to the setting of the inclined surface of the cleaning inclined plate 1013, the main scraper 97 and the secondary scraper 104 that can deflect by a certain amplitude with the fixed column 103 as the rotation center have a movement tendency to push the cleaning inclined plate 1013 to both sides during the movement. At this time, with the setting of the connecting spring 1012, the cleaning inclined plate 1013 is tightly attached to the side walls of the main scraper 97 and the secondary scraper 104, so as to scrape and clean the residues on their surfaces, thus ensuring that no secondary pollution will occur during the subsequent cleaning operation and improving the overall production efficiency of the device.

[0041] Please refer to the attached drawings of the specification Figure 6 and Figures 9-11 , in the embodiment of the present invention, a scraping assembly 11 for secondarily cleaning the surface of the cleaning inclined plate 1013 is arranged on the upper surface of the workbench 1. The scraping assembly 11 includes a toothed plate 111, and the toothed plate 111 is fixedly connected to the side wall of the guiding plate 910. A small gear 112 is rotatably installed on the outer wall of the mounting plate 91 near the base 5 side, and an L-shaped plate 113 is slidably installed on the outer wall of the mounting plate 91 near the base 5 side. One end of the L-shaped plate 113 close to the base 5 is fixedly installed with a support plate 114. A connecting member 115 is slidably installed on the inner wall of the support plate 114, the top of the connecting member 115 is fixedly connected to the lower surface of the cleaning block 1011, a sawtooth rack 116 is fixedly installed on the upper surface of the cleaning block 1011, and a discharge cavity 117 is formed in the inner wall of the cleaning block 1011. A secondary cleaning cavity 118 is formed in the inner wall of the discharge cavity 117 near the cleaning inclined plate 1013 side.

[0042] Specifically, a plurality of teeth meshing with the pinion 112 are provided on the outer wall of the L-shaped plate 113 close to the mounting plate 91, and the L-shaped plate 113 and the toothed plate 111 are respectively arranged on the left and right sides of the pinion 112, so that the toothed plate 111 and the L-shaped plate 113 can only move towards or away from each other in the vertical direction under the meshing drive of the pinion 112. At the same time, the support plate 114 is arranged directly below the mounting seat 109, and the support plate 114 is arranged with a higher center and lower sides. Specifically, the upper surfaces of both sides of the support plate 114 away from the center are arranged as inclined surfaces, so that the solid waste falling on the upper surface of the support plate 114 can slide down along the inclined surface and will not accumulate on the upper surface of the support plate 114, thus affecting the fitting between the top of the support plate 114 and the outer wall of the bottom of the mounting seat 109. Further, the connecting member 115 is arranged in a T shape, and a T-shaped sliding groove adapted to the connecting member 115 is provided on the inner wall of the top of the support plate 114, so that through the connection of the connecting member 115, only relative displacement can occur between the support plate 114 and the cleaning inclined plate 1013 in the horizontal direction, and they always move synchronously in the vertical direction.

[0043] At the same time, a trapezoidal straight groove adapted to the cleaning inclined plate 1013 is provided inside the cleaning block 1011, and the cleaning inclined plate 1013 is arranged inside the trapezoidal straight groove. In addition, a plurality of saw teeth are provided on the top of the sawtooth bar 116, and the sawtooth bar 116 is arranged on the top surface of the cleaning block 1011. At the same time, the surface of the sawtooth bar 116 with saw teeth is attached to the inclined surface of the cleaning inclined plate 1013. Further, another set of sawtooth belts are provided on the bottom surface of the side of the secondary cleaning cavity 118 close to the cleaning inclined plate 1013. At the same time, due to the through connection of the secondary cleaning cavity 118 and the discharge cavity 117, during the reset movement of the threaded plate 94, due to the relative movement of the guide post 913 and the guide groove 912, the guide plate 910 will drive the toothed plate 111 to move upward. At this time, in cooperation with the pinion 112, the L-shaped plate 113 drives the support plate 114 to move downward, and further drives the cleaning inclined plate 1013 to move downward relative to the cleaning block 1011 in cooperation with the connecting member 115, so that the sawtooth bar 116 and the sawtooth belts at the bottom of the secondary cleaning cavity 118 can clean the solid impurities on the surface of the cleaning inclined plate 1013 and then discharge them smoothly outward, and will not accumulate near the cleaning inclined plate 1013, affecting the subsequent cleaning effect of the cleaning inclined plate 1013 on the main scraper 97 and the secondary scraper 104, so as to ensure the stable operation of the device.

[0044] Please refer to the attached instructions Figures 1-3 and Figure 7, a reciprocating component 12 for improving the scraping and cleaning efficiency of the main scraper 97 and the auxiliary scraper 104 is provided on the side wall of the mounting plate 91. The reciprocating component 12 includes a contact ball 121, and the contact ball 121 is fixedly installed on the outer wall of the square rod 95. A connecting column 122 is fixedly installed on the outer wall of the mounting plate 91 close to one side of the base 5, and a guiding groove 123 is provided on the upper surface of the connecting column 122.

[0045] It should be noted that two sets of connecting columns 122 are provided, and the two sets of connecting columns 122 are respectively arranged on the left and right sides of the base 5, and the guiding grooves 123 at the tops of the two sets of connecting columns 122 are arranged in the same way. And two sets of contact balls 121 are provided, and the two sets of contact balls 121 are respectively arranged on the upper and lower outer walls at the ends of the square rod 95, and the two sets of contact balls 121 and the two sets of main scrapers 97 and auxiliary scrapers 104 are arranged in the same plane, so that when the square rod 95 rotates 180° and then returns with the threaded plate 94, it can still be guided and controlled in cooperation with the guiding groove 123. Further, both ends of the guiding groove 123 are arranged in a straight line, and the middle section of the guiding groove 123 is arranged in a wavy shape. Specifically, avoiding grooves are provided on the upper surfaces at both ends of the connecting column 122, and the depth of the avoiding groove is greater than the side length of the end of the square rod 95. Through the setting of the avoiding groove, the connecting column 122 will not cause movement interference to the rotation of the square rod 95. At the same time, the upper surface of the connecting column 122 is kept in contact with the lower surface of the square rod 95, and the outer wall of the threaded plate 94 away from the base 5 is in contact with the side wall of the connecting column 122. Thus, when the driving motor 92 is started to drive the threaded rod 93 to rotate, the threaded plate 94 is restricted by the connecting column 122 and can only move linearly along the outer wall of the connecting column 122, and will not rotate with the rotation of the threaded rod 93. Furthermore, during the movement of the threaded plate 94, due to the setting of the contact ball 121 on the outer wall of the end of the square rod 95, in cooperation with the wavy setting of the middle section of the guiding groove 123, the square rod 95 makes small left and right reciprocating movements while sliding along the connecting column 122. In cooperation with the connecting block 102 and the rectangular groove provided on the arc-shaped outer wall of the sleeve 96, the square column 101 and the main scraper 97 and the auxiliary scraper 104 are driven to make left and right reciprocating movements along the outer surface of the sleeve 96, thereby improving the cleaning effect of the main scraper 97 and the auxiliary scraper 104 on the upper surfaces of the base 5 and the push plate 8, and ensuring the normal development of the subsequent production work of the device.

[0046] In the present invention, during use, refractory materials are placed into the cavity 6. At this time, the hydraulic device 3 is activated, and in cooperation with the pressing block 4 and the protruding part provided on the lower surface of the pressing block 4, die-casting operation is performed on the refractory materials in the cavity 6 to form them. Then, the pressing block 4 is lifted by controlling the hydraulic device 3. After the top of the cavity 6 is exposed, the thruster 7 is activated, and in cooperation with the upward movement of the push plate 8 in the cavity 6, the formed refractory bricks are pushed out. The staff takes away the refractory bricks. At this time, the upper surface of the push plate 8 is flush with the upper surface of the base 5. Then, the drive motor 92 is activated, and in cooperation with the rotation of the threaded rod 93. At this time, restricted by the side wall of the connecting column 122, the threaded plate 94 can only perform linear motion along the side wall of the connecting column 122, thereby driving the sleeve 96 and the square column 101 on the side of the threaded plate 94, as well as the main scraper 97 and the secondary scraper 104 provided on the outer surface of the square column 101 to perform scraping operations on the upper surfaces of the base 5 and the push plate 8, thereby cleaning the waste chips and waste materials generated during the die-casting operation.

[0047] As the threaded rod 93 continues to rotate, when the threaded plate 94 drives the sleeve 96 close to the guide plate 910 at the end far from the drive motor 92, in cooperation with the tooth pattern provided on the lower surface of the guide plate 910, the large gear 98 is driven to rotate 180°, so as to realize the replacement of the main scraper 97 and the secondary scraper 104 directly below the sleeve 96 and the square column 101 with another set of main scraper 97 and secondary scraper 104 directly above the sleeve 96 and the square column 101. Then, by controlling the drive motor 92 to reverse, in cooperation with the rotation of the threaded rod 93, the threaded plate 94 performs a return movement, realizing the function of replacing the scraper for cleaning the surfaces of the base 5 and the push plate 8 as the threaded plate 94 returns to its original position, avoiding the residues of the scraper from being scattered on the surface of the base 5 or the push plate 8 as the threaded plate 94 moves in the reverse direction, thereby affecting the subsequent die-casting operation of the refractory bricks.

[0048] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
