[0001] The invention relates to the technical field of steel ingot mold casting production, and in particular to a modeling wooden mold for steel ingot mold castings and a manufacturing method thereof. Background Art

[0002] The steel ingot mold is an important mold for producing large steel ingots, and the steel ingot mold itself needs to be made by casting. The quality of the steel ingot mold casting will directly affect the quality and service life of the steel ingot produced by the steel ingot mold.

[0003] Most existing steel ingot mold castings are produced by sand casting. In the sand casting process, a wooden mold of the steel ingot mold assembly needs to be made to shape the cavity of the steel ingot mold casting. After pouring molten iron, the steel ingot mold casting can be obtained. Since the steel ingot mold assembly is large in size and has a ring structure, the production of its wooden mold is relatively difficult; in order to improve the strength and stability of the wooden mold, the use of plate materials is generally increased, and the mold is made by one-piece molding, which increases the consumption of wood and increases the production cost.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "middle", "upper", "lower", "left", "right", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying 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 direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0023] like Figures 1 to 3 As shown, a wooden mold for molding a steel ingot mold casting comprises a wooden frame 1, wherein the wooden frame 1 has an axial through hole, and the diameter of one end of the axial through hole is larger than the diameter of the other end; a plurality of plank assemblies 2 are laid on the inner and outer peripheries of the wooden frame 1, respectively, so as to obtain a wooden mold body that matches the inner and outer contours of the steel ingot mold casting; skirt assemblies 3 are respectively provided on the two ends and the middle of the wooden mold body, and the skirt assemblies 3 are connected to the plank assemblies 2 and / or the wooden frame 1; hanger core boxes 4 are also provided on both sides of the wooden mold body, and a core box installation position is reserved for the outer plank assembly 2 during production, and the hanger core box 4 is arranged at the core box installation position and connected to the wooden frame 1.

[0024] The molding wooden mold of the steel ingot mold casting can form a molding wooden mold structure with stable structure, good strength, large size and relatively light weight through the arrangement of the wooden frame 1, the decking assembly 2 and the skirt assembly 3. Moreover, the molding wooden mold is relatively simple to manufacture and has good plasticity. A wooden mold with basically the same outline size can be manufactured according to the shape of the required casting, so that the required large-scale steel ingot mold casting can be produced by molding through the wooden mold.

[0025] The wooden skeleton 1 is the basic frame structure of the wooden mold. By laying the plank components on the inner and outer peripheries thereof respectively, and arranging the skirt components and the handle core box, each component can be manufactured in a block and unit manner and then assembled, thereby reducing the difficulty of making the wooden mold.

[0026] The plank assembly 2 can be independently installed on the inner and outer peripheries of the wooden frame 1, which is convenient for its orderly installation and later repair. After the modeling wooden mold is made, it is not used only once, but will be used repeatedly and will be used every time for modeling. During the transportation and use of the modeling wooden mold, its internal and external structures will be more or less worn or damaged. The cost of remaking the wooden mold due to damage is high, so when damage occurs, it is mostly maintained by repairing it; the plank assembly of the present application can repair or replace each unit separately according to the damaged position, reducing the maintenance cost of the wooden mold, and these plank assemblies can also protect the internal wooden frame to avoid damage to the internal wooden frame, which can essentially improve the service life of the entire wooden mold.

[0027] The independent setting of the skirt component 3 and the hanger core box 4 also has the above-mentioned effects. Not only that, the skirt component and the hanger core box can also form a unique modeling structure to meet special requirements. For example, the skirt component can form a circular surrounding structure on the wooden mold body, and the hanger core box can produce a hanging ear structure with a smooth surface, no burrs and flash, and there are no defects that affect the strength around the hanging ear (within 2.5 times the diameter of the hanging ear).

[0028] In this embodiment, the axial dimension of the wooden mold body exceeds 3000mm, about 3200mm, and the inner and outer circumferential dimensions exceed 2000mm. The inner diameter of the wooden mold body is between 2250mm and 2500mm, and it is a structure with a larger top and a smaller bottom. The outer diameter of the wooden mold body is between 3400 and 3550mm.

[0029] Further, such as Figure 4 and Figure 5As shown, the wooden frame 1 includes a multi-layer mesh structure 5 arranged in parallel up and down, and the inner and outer peripheries of the mesh structure 5 are respectively provided with a plurality of bayonet holes 7, and the bayonet holes 7 are respectively connected to wooden squares 6, and the wooden squares 6 on the inner and outer peripheries are staggered.

[0030] The mesh ring structure 5 can form a basic inner and outer contour shape, and through the setting of multiple groups of upper, middle and lower groups, together with the wooden squares 6, can be connected together to form a three-dimensional structure; in addition to connecting and supporting several of the mesh ring structures, the setting of the wooden squares can also provide a certain connection strength to ensure the stability of the basic frame.

[0031] The bayonet connection method can significantly reduce the use of metal connectors such as screws. This connection structure, similar to the mortise and tenon joint, can not only ensure the connection strength, but also avoid the damage of the screw holes to the original structure of the wood, so as not to reduce its overall structural strength and stability.

[0032] This staggered arrangement of the inner and outer circumferences can not only reduce the total number of wooden squares, but also ensure the overall connection support strength. The wooden squares of the inner and outer circumferences are arranged 6 to 15 pieces respectively, for example, eight pieces are arranged each.

[0033] Furthermore, each of the mesh ring structures 5 comprises multiple layers of superimposed mesh rings 501, and the number of layers of the mesh rings 501 is 2 to 5; the mesh ring 501 is a polygonal structure, and the bayonet 7 is respectively arranged on the inner and outer edges of the polygonal structure, and the width of the mesh ring 501 plus the thickness of the decking assembly 2 is the cross-sectional width dimension of the ingot mold casting.

[0034] The number of sides of the polygonal structure is 14 to 30, generally an even number, so that it can be close to a circular ring, but not a circular ring; the spacing between adjacent mesh structures 5 does not exceed 700mm, preferably does not exceed 600mm. Too large a spacing will affect the overall strength and stability, and too small a spacing will consume more wood and the structure will be more complicated.

[0035] The size of the mesh ring 501 is determined by the cross section of the steel ingot mold casting minus the thickness of the floor plate. The thickness of a single layer of the mesh ring is the thickness of a general plate, such as about 35 mm.

[0036] Furthermore, the mesh ring structure 5 at the top is provided with three layers of mesh rings, the mesh ring structure 5 at the bottom is provided with four layers of mesh rings, and the multiple mesh ring structures 5 in the middle are respectively provided with two layers of mesh rings, and the multiple mesh ring structures in the middle are evenly distributed.

[0037] Each of the mesh circles 501 is a polygonal mesh circle. Due to the limitations of processing equipment and the size of the plate, it is difficult to form the mesh circles 501 in one piece. Each layer of the mesh circle can be milled into blocks and then connected by glue nails. In this way, it can be made in blocks according to the size of the template and then spliced ​​into polygonal circles, which is more convenient.

[0038] Further, such as Figure 7 As shown, the mesh ring structure 5 further includes a steel ring 9, which is arranged below the mesh ring 501 or between adjacent mesh rings 501, and an annular groove 10 connected to the steel ring 9 is provided on the mesh ring 501.

[0039] The arrangement of the steel ring 9 can further enhance the strength of the mesh ring structure 5 and improve the stress of the mesh ring assembly. For the wooden mold of the large ingot mold casting, the top and bottom are the main supporting and stress-bearing positions, and the steel ring is embedded in the bottom surface of the top mesh ring assembly, and the steel ring is embedded in the middle of the bottom mesh ring assembly.

[0040] Furthermore, the steel ring 9 is in a circular shape, the width of the steel ring 9 is smaller than the width of the mesh ring, the width of the steel ring 9 is about 100 mm, and the thickness of the steel ring 9 is 10 to 15 mm; the annular groove 10 provided on the mesh ring 5 can accommodate and install the steel ring 9.

[0041] Further, such as Figure 6 As shown, the wooden square 6 is provided with a plurality of notches 8 spaced apart along its length direction, and notches 8 are also provided at both ends of the wooden square 6, and the notches 8 cooperate with the bayonet 7 to connect the wooden square 6; vertical linings are also provided between adjacent mesh ring structures 5, and these vertical linings are connected between the upper and lower mesh rings, which can further support and fix each layer of the mesh ring structure, and is beneficial to improving the overall supporting strength and stability.

[0042] Furthermore, a plurality of demoulding suspension rods are provided in the wooden frame 1 , and the demoulding suspension rods are arranged parallel to the axial direction of the wooden frame 1 . Hanging rings are provided at the ends of the demoulding suspension rods, and the ends of the demoulding suspension rods and the hanging rings do not exceed the end surface of the wooden frame 1 .

[0043] The hanger locating holes 11 are arranged one by one on the mesh ring 5 and the steel ring 9. There are four hanger locating holes 11 evenly spaced at 90 degrees. A demolding hanger that penetrates and connects the entire frame structure can be arranged through the hanger locating holes 11. The entire wooden mold can be conveniently lifted by the demolding hanger and the lifting ring. Especially in the subsequent casting cavity molding process, these demolding lifting rings and the hanger can be used to take the sand mold out of the wooden mold.

[0044] The hanging ring is of hidden design and does not extend beyond the upper end surface of the uppermost mesh ring assembly. Such a setting does not affect the coordination between the wooden mold and other molding structures, such as the coordination with the cover box. The coordination will not be affected by the protruding hanging ring, and people and objects will not be scratched by the protruding ring or rod.

[0045] Further, combined with Figure 8 As shown, the plank assembly 2 includes an inner mold 201 and an inner plank 202, as well as an outer mold 203 and an outer plank 204; the inner mold 201 is axially connected to the inner periphery of the wooden frame 1, the inner plank 202 is connected to the outer surface of the inner mold 201, and a plurality of the inner molds 201 are circumferentially arranged in sequence on the inner periphery of the wooden frame 1; the outer mold 203 is axially connected to the outer periphery of the wooden frame 1, the outer plank 204 is connected to the outer surface of the outer mold 203, and a plurality of the outer molds 203 are circumferentially arranged in sequence on the outer periphery of the wooden frame 1 and reserve the core box installation position.

[0046] The inner mold 201 and the outer mold 203 are long strip plate structures, which are manufactured by independent processing. They can shape the mold body according to different shape requirements to form a unique inner and outer peripheral shape structure of the ingot mold casting; the setting of the inner floor plate 202 and the outer floor plate 204 can form a continuous and smooth inner and outer surface, and can also protect the internal mold and skeleton structure.

[0047] The wooden frame 1 ensures the strength of the model and saves materials, and the plank assembly 2 is used to shape the inner and outer surfaces of the model. In this embodiment, the cross-section of the ingot mold assembly is in the shape of plum petals, with 16 petals on the inner and outer sides. Limited by the size of the plate (35mm), the three-dimensional model is divided into blocks, and the planks are made in the shape of 1 / 2 petals of the same petal. The inner plank (inner mold) and the outer plank (outer mold) are both in the shape of petals, but one is convex and the other is concave. This ensures that the maximum thickness of the plate does not exceed 35mm, which meets the plate requirements, and the minimum thickness is also more than 20mm, which meets the strength requirements. Because there is a movable skirt at the bottom of the periphery, the length of the outer plank needs to be subtracted from the length of the movable skirt.

[0048] Furthermore, the skirt assembly 3 includes a movable skirt and a fixed skirt, and the fixed skirt and the movable skirt are respectively circumferentially connected to the outer periphery of the wooden mold body; the fixed skirt and the movable skirt both include a wooden skirt and a foam skirt.

[0049] The fixed skirt and the movable skirt refer to the installation form of the skirt. The fixed skirt is generally fixed and will not be replaced frequently, which does not mean that it is non-removable. The movable skirt is relatively flexible and easy to disassemble. It can be replaced with skirts of different sizes and shapes according to actual needs. This does not mean that the movable skirt is not fixed when connected.

[0050] The wooden skirt and the foam skirt mainly refer to the material of the skirt. The force and shape of the skirt model at different positions are different, and skirts of different materials will be selected accordingly to achieve the best assembly effect. In this embodiment, the upper side of the steel ingot mold casting model needs to be directly demolded, and a wooden fixed skirt is used to ensure its strength and stability. A foam movable skirt is used in the middle to ensure its smoothness. The movable wooden skirt is used below to be embedded in the main body and bring out the rounded corners, which has a certain strength and can be flexibly replaced.

[0051] Since the hanger of the ingot mold casting is a curved surface and has high requirements for smoothness and strength, the hanger core box is used to make a hanger model separately. Fig. 9 As shown, the handle core box 4 includes a mounting portion 401 and core-pulling molds 402 arranged at both ends of the mounting portion 401. The core-pulling molds 402 are used to make the handle, which can ensure that the cavity of the handle head is smoothly made, and the mold is easy to demold. It can be used multiple times, saving the cost of model making; the mounting portion 401 is snap-connected to the core box mounting position, and its shape is similar to the outer mold, and it also has a part of the skirt structure in the middle. This method can directly allow the handle core box to be installed on the wooden frame 1, and is compatible with the outer decking assembly and the skirt assembly.

[0052] A method for making a wooden mold for a steel ingot mold casting, the method comprising the following steps: A three-dimensional diagram of the wooden mold is established according to the process diagram of the steel ingot mold casting, and blocks are divided according to the three-dimensional diagram of the wooden mold to respectively design the wooden frame 1, the decking assembly 2 and the skirt assembly 3; The wooden frame 1 is assembled from a mesh ring 501, a steel ring 9, a mold-lifting rod, a wooden square 6 and a vertical lining. First, the inner and outer edges of the mesh ring 501 are respectively processed with a bayonet 7, and a notch 8 is processed on the wooden square 6. The mesh ring 501 and the steel ring 9 are respectively provided with corresponding rod positioning holes 11. Secondly, multiple mesh rings 501 are stacked together to form multiple mesh ring structures 5. The top mesh ring structure is 3 layers of board material, the bottom mesh ring structure is 4 layers of board material, and the middle mesh ring structure is 2 layers, which are evenly distributed. The top and bottom mesh ring structures are connected to the steel ring 9. If there is a wooden movable skirt at the bottom of the wooden mold of the steel ingot mold, the upper part of the wooden movable skirt needs to be supported, and a layer of mesh can be made of a single-layer plate at the upper part of the wooden movable skirt; multiple mesh structures 5 are arranged at intervals, and the interval is not higher than 600mm, and the wooden square 6 is installed on the inner and outer peripheries of the mesh structure 5, and the notch 8 is engaged with the bayonet 7, and they are fixed to each other; finally, the demoulding suspension rod is connected to the suspension rod positioning hole 11, and a suspension ring is set at the upper end, and then a plurality of the vertical linings are fixedly connected between adjacent mesh structures 5 to further support these mesh circles; The plank assembly 2 is manufactured, and a plurality of inner molds 201 and inner planks 202, as well as outer molds 203 and outer planks 204 are processed respectively according to the inner and outer contours of the ingot mold, and the inner planks 202 are attached to the inner mold 201, and the outer planks 204 are attached to the outer mold 203; the inner mold 201 is sequentially and tightly laid on the inner periphery of the wooden frame 1 and fastened, and the outer mold 203 is laid on the outer periphery of the wooden frame 1 and fastened, and the core box installation positions are reserved on both sides of the wooden frame 1; after laying the plank assembly, the wooden mold body is obtained; the hanger core box 4 is arranged at the core box installation position and connected to the wooden frame 1; The skirt assembly 3 is manufactured by manufacturing a plurality of wooden fixed skirts, wooden movable skirts and foam movable skirts according to the skirt molding shape; a wooden fixed skirt is arranged at the upper end of the wooden mold body, a foam movable skirt is adopted in the middle and fixed to the wooden mold body by double-sided tape; a wooden movable skirt is arranged at the lower end and embedded in the wooden mold body.

[0053] After assembly is completed, the corners and excess parts are polished, and the release agent is applied to the inner and outer circumferential surfaces and end faces respectively to obtain the final wooden mold. After passing the inspection, it is put into storage for use.

[0054] By using the above method to produce the shaped wooden mold, the difficulty of producing large-scale wooden molds with complex structures and many curved and bent surfaces can be reduced. Through reasonable block design, each unique component can be produced more conveniently, and a three-dimensional structure can be formed after combination to meet the unique shaped structural requirements of the steel ingot mold. Moreover, the processing and production processes can be standardized to ensure that the quality of the wooden mold produced each time is guaranteed.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
