Description

Technical Field

[0001] This utility model relates to the field of casting technology, specifically to a frame structure for shaping wooden molds of steel ingot castings. Background Technology

[0002] Steel ingot molds are important molds for producing large steel ingots. The steel ingot molds themselves are also made by casting. The quality of the steel ingot mold castings directly affects the quality and service life of the steel ingots produced by the steel ingot molds.

[0003] Most existing steel ingot castings are produced through sand casting. The sand casting process requires the creation of a wooden mold for the steel ingot mold assembly to shape the mold and form the cavity for the casting. After pouring molten iron, the steel ingot casting is obtained. Because the steel ingot mold assembly is relatively large and has a ring-shaped structure, the production of its wooden mold is quite difficult. To improve the strength and stability of the wooden mold, the amount of wood used is generally increased, and a one-piece molding method is often adopted. This approach further increases wood consumption and production costs. Summary of the Invention

[0004] The purpose of this utility model is to address the problems existing in the prior art by providing a frame structure for shaping wooden molds of steel ingot castings.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A frame structure for molding a wooden mold of a steel ingot casting includes several wooden mesh ring components and several wooden blocks connected to the mesh ring components; the mesh ring components are spaced apart and arranged in parallel, and several slots are provided on the inner and outer circumferences of the mesh ring components respectively, with the slots on adjacent mesh ring components arranged correspondingly, and the slots on the inner and outer circumferences respectively engaging and connecting the wooden blocks.

[0007] The wooden mold frame structure for shaping steel ingot castings, through the arrangement of the mesh ring assembly and the wooden blocks, can form a stable, large, and relatively lightweight wooden model frame structure, which is conducive to the subsequent construction of a complete wooden mold, so as to produce the required large steel ingot castings through the shaping of the wooden mold.

[0008] The mesh ring components can form basic inner and outer contour shapes. Through the arrangement of multiple sets at the top, middle, and bottom, and with the wooden blocks, they can be connected together to form a three-dimensional structure. In addition to connecting and supporting several mesh ring components, the wooden blocks can also form a basic structure, provide a certain connection strength, and ensure the stability of the basic frame.

[0009] Using a bayonet connection method can significantly reduce the use of metal connectors such as screws. This mortise and tenon-like connection structure can ensure connection strength and avoid damage to the original structure of the wood by screw holes, so as not to reduce its overall structural strength and stability.

[0010] Furthermore, the mesh ring component is a polygonal mesh ring structure, and the locking slots are respectively set on the inner and outer edges of the polygonal mesh ring structure. The interval between adjacent mesh ring components does not exceed 700mm. If the interval is too large, it will affect the overall strength and stability, and if the interval is too small, it will consume more wood.

[0011] Furthermore, the mesh ring assembly includes multiple layers of stacked mesh rings, the outline area of ​​which is smaller than the cross-sectional area of ​​the steel ingot mold casting, and the number of mesh ring layers is 2 to 5.

[0012] Preferably, the top mesh assembly has three layers of mesh, the bottom mesh assembly has four layers of mesh, and the middle mesh assemblies each have two layers of mesh. This arrangement can improve the structural strength of the top and bottom mesh assemblies.

[0013] Furthermore, the mesh ring assembly also includes a steel ring, which is disposed below or in the middle of the mesh ring assembly, thereby further enhancing the strength of the mesh ring assembly and improving its stress resistance.

[0014] Furthermore, the steel ring is circular, the width of the steel ring is smaller than the width of the mesh ring assembly, and the thickness of the steel ring is 10-15mm; the mesh ring assembly is provided with an annular groove, and the annular groove connects to the steel ring.

[0015] Furthermore, the timbers on the inner and outer perimeters are staggered, with 6 to 15 timbers on each perimeter. This staggered arrangement reduces the total number of timbers while ensuring the overall connection and support strength.

[0016] Furthermore, the timber has several notches spaced apart along its length, and notches are also provided at both ends of the timber. The notches cooperate with the latches to connect the timber.

[0017] Furthermore, the mesh ring assembly is also provided with several lifting ring positioning holes, and the lifting ring positioning holes are connected to a lifting rod that is connected in series with several mesh ring assemblies. The end of the lifting rod is provided with a lifting ring, which facilitates the lifting of the entire frame structure and the wooden mold structure subsequently made based on the frame structure.

[0018] Furthermore, several vertical supports are provided between adjacent mesh ring components to further enhance the connection strength and support stability between the mesh ring components.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The frame structure for shaping the wooden mold of the steel ingot casting, through the setting of the mesh ring component and the wooden blocks, can form a stable, large-sized, and relatively lightweight wooden model frame structure, which is conducive to the subsequent construction of the complete wooden mold, so as to produce the required large steel ingot castings through the shaping of the wooden mold; 2. The mesh ring component can form a basic inner and outer contour shape. Through the setting of multiple sets at the top, middle, and bottom, and with the wooden blocks, they can be connected together to form a three-dimensional structure; the setting of the wooden blocks, in addition to connecting and supporting several mesh ring components, can also form a basic structure, provide a certain connection strength, and ensure the stability of the basic frame; 3. The setting of the steel ring can further improve the strength of the mesh ring component and improve the stress of the mesh ring component; 4. The use of bayonet and notch connection method can significantly reduce the use of metal connectors such as screws, which can ensure the connection strength and avoid the damage of screw holes to the original structure of the wood.

[0027] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] In the description of this utility model, it should be noted that the terms "middle," "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model 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 utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] like Figures 1-5 As shown, a frame structure for molding a wooden mold of a steel ingot casting includes several wooden mesh ring components 1 and several wooden blocks 2 connected to the mesh ring components 1; the mesh ring components 1 are spaced apart and arranged in parallel, and several slots 3 are provided on the inner and outer circumferences of the mesh ring components 1 respectively, and the slots on adjacent mesh ring components 1 are arranged correspondingly, and the slots 3 on the inner and outer circumferences respectively engage and connect the wooden blocks 2.

[0030] The wooden mold frame structure for shaping the steel ingot casting, through the setting of the mesh ring component 1 and the wooden block 2, can form a stable, large and relatively lightweight wooden model frame structure, which is conducive to the subsequent construction of the complete wooden mold, so as to produce the required large steel ingot castings through the shaping of the wooden mold.

[0031] In this embodiment, the axial dimension of the frame structure exceeds 3000mm and is around 3200mm, and the inner and outer circumference dimensions exceed 2000mm. The inner circumference diameter of the frame structure is between 2250mm and 2500mm, and it is a structure that is larger at the top and smaller at the bottom. The outer circumference diameter of the frame structure is between 3400mm and 3550mm.

[0032] The mesh ring component 1 can form a basic inner and outer contour shape. Through the arrangement of multiple sets at the top, middle and bottom, and with the wooden blocks 2, they can be connected together to form a three-dimensional structure. In addition to connecting and supporting several mesh ring components, the wooden blocks can also form a basic structure, provide a certain connection strength, and ensure the stability of the basic frame.

[0033] The use of bayonet 3 connection method can significantly reduce the use of metal connectors such as screws. This mortise and tenon-like connection structure can ensure connection strength and avoid damage to the original structure of wood by screw holes, so as not to reduce its overall structural strength and stability.

[0034] Furthermore, the mesh ring component 1 is a polygonal mesh ring structure with 14 to 30 sides, generally an even number, so that it is close to a circle, but not a circle; the latches 3 are respectively set on the inner and outer sides of the polygonal mesh ring structure, and the interval between adjacent mesh ring components 1 does not exceed 700mm, preferably not more than 600mm. If the interval is too large, it will affect the overall strength and stability, and if the interval is too small, it will consume more wood and the structure will be more complex.

[0035] Furthermore, the mesh ring assembly 1 includes multiple layers of stacked mesh rings 101. The outline area of ​​the mesh rings 101 is smaller than the cross-sectional area of ​​the steel ingot mold casting. That is, the size of the mesh rings 101 is determined by subtracting the thickness of the paving plate from the cross-sectional area of ​​the steel ingot mold casting. The paving plate 8 is a plate subsequently laid on the inner and outer periphery of the frame structure to form the inner and outer wall structure of the wooden mold 9, such as... Figure 6 As shown. The thickness of a single layer of the mesh ring 101 is the same as that of a typical sheet metal, such as about 35mm.

[0036] The mesh ring 101 has 2 to 5 layers. Preferably, the top mesh ring assembly has three layers, the bottom mesh ring assembly has four layers, and the middle mesh ring assemblies each have two layers, and the middle mesh ring assemblies are evenly distributed.

[0037] Each of the mesh rings 101 is a polygonal mesh ring. Due to limitations in processing equipment and the size of the sheet material, it is difficult to integrally mold the mesh rings. Instead, each layer of mesh rings can be milled into sections and then connected with glue nails. This allows for production in sections according to the sample size, which is more convenient.

[0038] Furthermore, the mesh ring assembly 1 also includes a steel ring 5, which is disposed below or in the middle of the mesh ring assembly 1.

[0039] The steel ring 5 can further enhance the strength of the mesh ring assembly 1 and improve the stress on the mesh ring assembly 1. For the wooden mold of large steel ingot casting, its top and bottom are the main support and stress-bearing positions. Therefore, the bottom surface of the uppermost mesh ring assembly is inlaid with a steel ring, and the middle of the lowermost mesh ring assembly is inlaid with a steel ring.

[0040] Furthermore, the steel ring 5 is annular, the width of the steel ring 5 is smaller than the width of the mesh ring assembly 1, the width of the ring of the steel ring 5 is about 100mm, and the thickness of the steel ring 5 is 10-15mm; the mesh ring 101 is provided with an annular groove 6, and the annular groove 6 connects to the steel ring 5.

[0041] Furthermore, the timber 2 on the inner and outer perimeters is staggered, with 6 to 15 timber 2 on each side, for example, eight on each side. This staggered arrangement of the inner and outer perimeters reduces the total number of timber 2 pieces while ensuring the overall connection and support strength.

[0042] Furthermore, the timber 2 has several notches 4 spaced apart along its length, and notches 4 are also provided at both ends of the timber 2. The notches 4 cooperate with the latches 3 to connect the timber.

[0043] Furthermore, the mesh ring assembly 1 is also provided with a plurality of mold-lifting ring positioning holes 7, and the mold-lifting ring positioning holes 7 are connected to a series of lifting rods of the mesh ring assemblies 1, and the end of the lifting rod is provided with a lifting ring (not shown in the figure).

[0044] The mold-lifting ring positioning holes 7 are provided one-to-one on the mesh ring 101 and the steel ring 5. There are four mold-lifting ring positioning holes 7 evenly distributed at 90-degree intervals. A lifting rod can be installed through these positioning holes 7, connecting the entire frame structure. The lifting rod and the lifting rings allow for convenient lifting of the entire wooden mold, especially useful in the subsequent casting cavity molding process, where these lifting rings and rods can be used to remove the sand mold from the wooden mold. Preferably, the lifting rings are of a concealed design, not extending beyond the uppermost mesh ring assembly.

[0045] Furthermore, several vertical supports (not shown in the figure) are provided between adjacent mesh ring components 1. These vertical supports are connected between the upper and lower mesh rings and can further support and fix each layer of mesh ring components, which helps to improve the overall support strength and stability.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
