Description

Technical Field

[0001] This invention relates to the field of checkerboard refractory brick production technology, and in particular to checkerboard brick molds and their assembly methods. Background Technology

[0002] High-tonnage hydraulic brick presses employ fully automatic control. With the advancement of Industry 4.0, intelligent and smart production lines have gradually become widespread. The forming system is a crucial component, consisting of either an electric screw brick press or a fully automatic hydraulic brick press. Relatively speaking, hydraulic brick presses offer a higher degree of automation, greater pressure, and better product quality. The refractory molds used on the hydraulic press determine the product's appearance quality and production efficiency, and also significantly impact its internal quality and degree of automation.

[0003] Due to the extremely high requirements for structural rationality, design precision, manufacturing precision, assembly precision, and durability, the molds for fully automatic hydraulic brick presses can currently only produce standard-shaped refractory brick molds. However, checkerboard refractory bricks have complex shapes and cannot be produced using automatic presses. Furthermore, checkerboard refractory bricks serve as heat exchangers in blast furnace hot blast stoves in the metallurgical industry. The combustion gases in the hot blast stoves contain CO and sulfur ions that corrode the checkerboard refractory bricks, shortening their service life. This results in a large demand for checkerboard refractory bricks, but traditional production methods affect delivery cycles. Therefore, there is an urgent need to design and manufacture a checkerboard brick mold that can be adapted to fully automatic hydraulic brick presses. Summary of the Invention

[0004] The purpose of this invention is to provide a checker brick mold and its assembly method in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0013] Preferably, the mold base core assembly further includes:

[0014] The lower mounting plate has a lower grid hole column on its upper plate surface corresponding to the position of the chamber. The upper end of the lower grid hole column is detachably connected to a lower grid hole column head, and the grid hole diameter in the lower grid hole column head is smaller than the grid hole diameter in the lower grid hole column.

[0015] Preferably, the core rod is a stepped rod, the upper section of the core rod is a large-diameter section, and the diameter of the upper section of the core rod is adapted to the diameter of the grid hole in the lower grid hole column head.

[0016] Preferably, the mounting frame includes two frames located on both sides of the lower grid post, with the upper ends of the two frames fixed to the mold assembly, and a plurality of mounting rods corresponding to the through holes provided between the bottoms of the two frames, with the lower end of the core rod detachably mounted to the corresponding mounting rod.

[0017] Preferably, the pressure head assembly includes:

[0018] The upper mounting plate has an upper grid hole column on its lower plate surface corresponding to the position of the chamber. The lower end of the upper grid hole column has an upper grid hole head. The diameter of the grid hole in the upper grid hole head is smaller than the diameter of the grid hole in the upper grid hole column, and the diameter of the grid hole in the upper grid hole head is adapted to the diameter of the core rod.

[0019] The present invention also provides a method for assembling a checker brick mold, comprising the following steps:

[0020] Assembly of the mold sleeve assembly: First, place the outer mold sleeve on the platform. Then, arrange several inner mold sleeves in a matrix inside the outer mold sleeve. Next, place a wedge plate at the position of each column or row of inner mold sleeves, and then place another wedge plate and press it down so that the two wedge plates fit tightly together. At this time, the longitudinal or transverse position of the inner mold sleeve is fixed. Then, according to the above principle, place a small plate structure at the position of each row or column of inner mold sleeves to fix the transverse or longitudinal position of the inner mold sleeves. At this time, all the inner mold sleeves are stably fixed inside the outer mold sleeve. Then, place the cover plate on the top of the outer mold sleeve. Then, insert all the upper grid holes through the corresponding cover plate clearance holes and insert them into the inner mold sleeves. Then, install the cover plate on the top of the outer mold sleeve. According to the cover plate installation principle, install the bottom plate on the bottom of the outer mold sleeve.

[0021] Assembly of the mold base core assembly: Insert all the lower grid hole posts into the inner mold sleeve one by one, and then install the lower mounting plate at the lower end of the lower grid hole posts; then, insert all the mounting rods horizontally through the corresponding through holes, and then insert the lower ends of all the core rods into the grid holes in the lower grid hole posts one by one, and then install the core rods to the corresponding mounting rods by screwing them on; then, install the frame at the same end of all the mounting rods, and then install the frame onto the mold sleeve assembly;

[0022] Assembly of the pressure head assembly: Insert all the upper grid hole posts into the inner mold sleeve one by one, then install the upper mounting plate on the upper end of all the upper grid hole posts, and then remove the upper grid hole posts.

[0023] Installation of the checker brick mold: First, install the mold sleeve assembly on the lower lifting part of the fully automatic hydraulic brick press; then place the lower mounting plate on the worktable of the fully automatic hydraulic brick press, move the lower lifting part of the fully automatic hydraulic brick press downward, and at the same time adjust the position of the lower mounting plate so that the lower grid hole column is inserted into the inner cavity of the inner mold sleeve. Finally, install the lower mounting plate on the worktable of the fully automatic hydraulic brick press; then move the lower lifting part of the fully automatic hydraulic brick press upward so that there is no lower grid hole column in the upper section of the inner cavity of the inner mold sleeve, then insert the upper grid hole column into the inner cavity of the inner mold sleeve, and then move the upper lifting part of the fully automatic hydraulic brick press downward so that the upper mounting plate is in contact with the bottom surface of the upper lifting part of the fully automatic hydraulic brick press, and then install the upper mounting plate on the upper lifting part of the fully automatic hydraulic brick press.

[0024] Preferably, the assembly of the inner mold sleeve is as follows: First, attach the six surrounding plates to the outer surfaces of the six inner lining plates respectively. Then, use tooling to adjust the positions of the inner lining plates and surrounding plates so that the six inner lining plates form a hollow hexagonal prism, and the sidewalls of two adjacent inner lining plates are in contact with each other. Then, weld the two adjacent surrounding plates together so that the six surrounding plates form a hexagonal sleeve.

[0025] The beneficial effects are:

[0026] 1. This grid brick mold solves the technical problem that the complex shape of grid refractory bricks makes it impossible to use an automatic press for production, thus improving the production efficiency of grid refractory bricks.

[0027] 2. Because the base plate and cover plate can protect the inner lining plate, the lower grid hole column head can protect the lower grid hole column, and the upper grid hole column head can protect the upper grid hole column, the grid brick mold has a low maintenance cost.

[0028] 3. Due to the segmented design of the core rod, when the core rod is damaged, only the damaged part can be replaced, reducing the maintenance cost of the core rod.

[0029] 4. This checker brick mold can be used in conjunction with a fully automatic hydraulic press, an automatic material feeding machine, and a robotic arm to achieve the function of automatically forming checker bricks. The production process does not require manual intervention, thus saving human resources.

[0030] 5. Due to the design of the mold assembly, multiple grid bricks can be produced at once, improving the labor efficiency of refractory production.

[0031] The additional technical features and advantages of the present invention will become more apparent from the following description, or may be learned through practice of the invention. Attached Figure Description

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0047] In the description of this invention, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing the invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0048] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0049] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0050] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0051] In this invention, unless otherwise expressly specified and limited, "above or below" a first feature may include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on" the first feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the first feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0052] Example 1, as Figure 1-2 As shown, the checker brick mold includes a mold sleeve assembly 1, a mold bottom core assembly 2, and a pressure head assembly 3.

[0053] The mold assembly 1 has several open chambers at the top and bottom to facilitate the molding of the outer contour of the checker bricks;

[0054] Furthermore, such as Figure 3As shown, the mold assembly 1 includes an outer mold 11, and a number of inner molds 12 arranged in a matrix are provided on the inner side of the outer mold 11. A set of tip plate structures 13 is provided on the inner side of the outer mold 11 corresponding to the position of each column and each row of inner molds 12, so as to fix the position of the inner molds 12.

[0055] As needed, filling plates are provided between adjacent inner mold sleeves 12 and between the inner mold sleeve 12 and the inner wall of the outer mold sleeve 11. This arrangement can fix the size of the outer mold sleeve 11. Different sizes of filling plates are selected according to the size and quantity of the inner mold sleeves 12 and cooperate with the tip plate structure 13 so that the inner mold sleeves 12 of various sizes and quantities can be stably fixed inside the outer mold sleeve 11.

[0056] Furthermore, such as Figure 5 As shown, the tip plate structure 13 includes two wedge plates. The inclined surfaces of the two wedge plates abut against each other, and the back surfaces of the two wedge plates are parallel. This arrangement allows the thickness of the tip plate structure 13 to change by adjusting the position between the two wedge plates, thereby making the inner mold sleeve 12 tightly clamped inside the outer mold sleeve 11, ensuring that the position of the inner mold sleeve 12 is fixed.

[0057] As needed, the height of the wedge plate is less than the height of the inner mold sleeve 12;

[0058] Furthermore, such as Figure 3 As shown, the bottom of the outer mold sleeve 11 is provided with a base plate 14, and the base plate 14 is provided with a clearance hole corresponding to the position of the inner cavity of the inner mold sleeve 12; the top of the outer mold sleeve 11 is provided with a cover plate 15, and the cover plate 15 is provided with a clearance hole corresponding to the position of the inner cavity of the inner mold sleeve 12; this arrangement can clamp the bottom and top surfaces of the inner mold sleeve 12 through the base plate 14 and the cover plate 15, further ensuring the fixation of the position of the inner mold sleeve 12. At the same time, during use, it can not only prevent raw materials from entering the inner cavity of the outer mold sleeve 11, but also prevent the inner liner plate 122 from colliding with the pressure head assembly 3 and the mold sleeve assembly 1 due to positional deviation, thus preventing damage to the inner liner plate 122.

[0059] During assembly, first, place the outer mold sleeve 11 on the platform, then place several inner mold sleeves 12 in a matrix arrangement inside the outer mold sleeve 11. Then, place a wedge plate at the position of each column or row of inner mold sleeves 12, and then place another wedge plate and press it down so that the two wedge plates fit tightly together. At this time, the longitudinal or transverse position of the inner mold sleeve 12 is fixed. Then, according to the above principle, place a small plate structure 13 at the position of each row or column of inner mold sleeves 12 to fix the transverse or longitudinal position of the inner mold sleeve 12. At this time, all the inner mold sleeves 12 are stably fixed inside the outer mold sleeve 11. Then, place the cover plate 15 on the top of the outer mold sleeve 11, and then insert all the upper grid hole pillars 31 through the corresponding cover plate 15 clearance holes and into the inner mold sleeves 12. Then, install the cover plate 15 on the top of the outer mold sleeve 11. According to the installation principle of the cover plate 15, install the bottom plate 14 on the bottom of the outer mold sleeve 11.

[0060] Furthermore, such as Figure 4 As shown, the inner mold sleeve 12 includes a hexagonal sleeve 121. Each inner sidewall of the hexagonal sleeve 121 is fitted with an inner liner plate 122, and the sidewalls of two adjacent inner liner plates 122 abut against each other. Each of the two opposite corners of the hexagonal sleeve 121 is provided with a square pad 16 with a V-shaped groove in the middle of its inner side, and the two groove walls of the V-shaped groove in the square pad 16 are fitted with the corresponding sidewalls of the corners of the hexagonal sleeve 121.

[0061] In the specific manufacturing process, firstly, the six side panels are respectively attached to the outer surfaces of the six inner lining panels 122. Then, the positions of the inner lining panels 122 and the side panels are adjusted using tooling so that the six inner lining panels 122 form a hollow hexagonal prism, and the side walls of two adjacent inner lining panels 122 are correspondingly abutted and attached. Then, the two adjacent side panels are welded together so that the six side panels form a hexagonal sleeve 121.

[0062] like Figure 6-8 As shown, the mold bottom core assembly 2 has a mounting frame 21 and lower grid hole pillars 22 corresponding to the cavities. The top of the lower grid hole pillar 22 is inserted into the bottom of the corresponding cavity. The lower section of the lower grid hole pillar 22 is provided with a through hole 221 that radially penetrates the grid hole at the position of each column or row of grid holes. Each grid hole in the lower grid hole pillar 22 is matched with a core rod 23 that can move axially, and the upper end of the core rod 23 extends to the top of the cavity to facilitate the formation of the bottom surface of the grid brick and the grid hole. The bottom of the mounting frame 21 passes through the corresponding through hole 221 and is detachably connected to the lower end of the corresponding core rod 23. The mounting frame 21 is fixedly connected to the mold sleeve assembly 1 to facilitate the mounting frame 21 and the core rod 23 to descend with the mold sleeve assembly 1 to complete the demolding operation of the grid brick.

[0063] Depending on the requirements, the upper end of the core rod 23 is a dome or a ball head.

[0064] Furthermore, such as Figure 6-7As shown, the mold base core assembly 2 also includes a lower mounting plate 24. The upper plate of the lower mounting plate 24 is provided with a lower grid hole post 22 at the position corresponding to the cavity. The upper end of the lower grid hole post 22 is detachably connected to a lower grid hole post head 25, and the grid hole diameter in the lower grid hole post head 25 is smaller than the grid hole diameter in the lower grid hole post 22.

[0065] As needed, the lower end of the lower grid hole column 22 is provided with a frustum, which has multiple elliptical holes along its circumference and is connected to the lower mounting plate 24 by bolts. The position of the lower grid hole column 22 can be slightly adjusted according to actual needs to ensure that all the lower grid hole columns 22 are coaxial with the corresponding inner mold sleeve 12.

[0066] Because of the setting of the lower grid hole column head 25, the lower grid hole column 22 can be protected. When the top of the mold bottom core assembly 2 is damaged, only the lower grid hole column head 25 needs to be replaced, which reduces maintenance costs. Furthermore, because the grid hole in the lower grid hole column head 25 is tightly slidably fitted with the core rod 23, when the mold bottom core assembly 2 is worn, only the lower grid hole column head 25 needs to be replaced, which further reduces maintenance costs.

[0067] Furthermore, such as Figure 8 As shown, the core rod 23 is a stepped rod, the upper section of the core rod 23 is a large diameter section, and the diameter of the upper section of the core rod 23 is matched with the diameter of the grid hole in the lower grid hole column head 25;

[0068] As needed, the core rod 23 is composed of two rods with different diameters. The upper end of the smaller diameter rod is coaxially screwed to the larger diameter rod, and the lower end of the smaller diameter rod is screwed to the mounting rod 212. With this configuration, when the core rod 23 is worn, only the larger diameter rod needs to be replaced, which reduces the cost of replacing the core rod 23.

[0069] Furthermore, the length of the large-diameter rod is not less than the thickness of the inner mold sleeve 12.

[0070] Furthermore, such as Figure 2 , 8 As shown, the mounting frame 21 includes two frame bodies 211 located on both sides of the lower grid post 22. The upper ends of the two frame bodies 211 are fixed to the mold assembly 1. A number of mounting rods 212 corresponding to the through holes 221 are provided between the bottoms of the two frame bodies 211. The lower end of the core rod 23 can be detachably installed on the corresponding mounting rod 212.

[0071] Furthermore, the width of the mounting rod 212 is the same as the width of the through hole 221;

[0072] As needed, the mounting rod 212 slides vertically into the through hole 221;

[0073] As needed, to facilitate the removal of the mounting rod 212 from the frame 211, the lower end of the frame 211 is provided with a strip-shaped hole along its length. Preferably, the width of the strip-shaped hole is the same as the thickness of the mounting rod 212, and the end of the mounting rod 212 is fitted into the strip-shaped hole. Preferably, the frame 211 is an I-shaped frame. As needed, when the length of the frame 211 is large, vertical reinforcing rods can be provided on both sides of the frame 211 to ensure the strength of the frame 211. This arrangement not only allows the mounting rod 212 to move up and down stably through the frame 211, but also allows the disassembly of the frame 211 and the mounting rod 212 to be completed simply by removing the frame 211 from the mold assembly 1.

[0074] During assembly, all the lower grid hole posts 22 are inserted into the inner mold sleeve 12 one by one, and then the lower mounting plate 24 is installed at the lower end of the lower grid hole posts 22. Then, all the mounting rods 212 are inserted through the through holes 221 one by one in the transverse direction. Then, the lower ends of all the core rods 23 are inserted into the grid holes in the lower grid hole posts 22 one by one, and then the core rods 23 are installed on the corresponding mounting rods 212 by screwing. Then, the frame body 211 is installed on the same end of all the mounting rods 212, and then the frame body 211 is installed on the mold sleeve assembly 1. This assembly can ensure that the lower grid hole posts 22 are coaxial with the inner cavity of the corresponding inner mold sleeve 12 and are not affected by installation tolerances.

[0075] like Figure 9 As shown, the pressure head assembly 3 has an upper grid hole column 31 that corresponds one-to-one with the lower grid hole column 22, so that the upper grid hole column 31 can press the raw material in the lower chamber and form the grid brick; the upper end of the grid hole in the upper grid hole column 31 is provided with an exhaust hole 311. The exhaust hole 311 can be set to facilitate the discharge of air from the grid hole in the upper grid hole column 31 after the grid hole in the upper grid hole column 31 is engaged with the core rod 23.

[0076] Furthermore, such as Figure 9 As shown, the pressure head assembly 3 includes an upper mounting plate 32. The lower plate of the upper mounting plate 32 is provided with an upper grid hole post 31 at the position corresponding to the chamber. The lower end of the upper grid hole post 31 is provided with an upper grid hole head 33. The diameter of the grid hole in the upper grid hole head 33 is smaller than the diameter of the grid hole in the upper grid hole post 31, and the diameter of the grid hole in the upper grid hole head 33 is adapted to the diameter of the core rod 23.

[0077] As needed, such as Figure 9 As shown, the upper grid post 31 has a frustum at its upper end. The frustum has multiple elliptical holes along its circumference and is connected to the upper mounting plate 32 by bolts. The position of the upper grid post 31 can be slightly adjusted according to actual needs to ensure that all the lower grid posts 22 are coaxial with the corresponding inner mold sleeve 12.

[0078] This design, due to the upper grid hole head 33, can protect the upper grid hole column 31. When the top of the pressure head assembly 3 is damaged, only the upper grid hole head 33 needs to be replaced, reducing maintenance costs. Furthermore, because the grid hole in the upper grid hole head 33 is tightly slidably fitted with the core rod 23, when the pressure head assembly 3 is worn, only the upper grid hole head 33 needs to be replaced, further reducing maintenance costs.

[0079] During assembly, insert all the upper grid hole posts 31 into the inner mold sleeve 12 one by one, then install the upper mounting plate 32 on the upper end of all the upper grid hole posts 31, and then remove the upper grid hole posts 31.

[0080] During installation, such as Figure 10 As shown, first, install the mold sleeve assembly 1 on the lower lifting part of the fully automatic hydraulic brick press; then place the lower mounting plate 24 on the worktable of the fully automatic hydraulic brick press, move the lower lifting part of the fully automatic hydraulic brick press downward, and adjust the position of the lower mounting plate 24 so that the lower grid hole column 22 is inserted into the inner cavity of the inner mold sleeve 12. Finally, install the lower mounting plate 24 on the worktable of the fully automatic hydraulic brick press; then move the lower lifting part of the fully automatic hydraulic brick press upward so that the lower grid hole column 22 is no longer present in the upper section of the inner cavity of the inner mold sleeve 12, then insert the upper grid hole column 31 into the inner cavity of the inner mold sleeve 12, and then move the upper lifting part of the fully automatic hydraulic brick press downward so that the upper mounting plate 32 is in contact with the bottom surface of the upper lifting part of the fully automatic hydraulic brick press, and then install the upper mounting plate 32 on the upper lifting part of the fully automatic hydraulic brick press.

[0081] When using it, the following steps are included:

[0082] Step 1: Feed material using an automatic material feeding machine;

[0083] Step 2: The lifting part of the fully automatic hydraulic brick press presses down, and the upper grid hole column head 33 enters the inner mold sleeve 12 to complete the pressurization;

[0084] Step 3: The upper lifting part of the fully automatic hydraulic brick press is reset, and the lower lifting part of the fully automatic hydraulic brick press moves downward, driving the mold sleeve assembly 1 and the mounting frame 21. The mounting frame 21 drives the core rod 23 to move downward. During this process, the brick blank is blocked by the lower grid hole column head 25 and does not move, thus completing the demolding.

[0085] Step 4: Use a robotic arm to clamp the brick blank and move it to complete the unloading process.

[0086] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
