Description

Technical Field

[0001] This utility model relates to the field of mold technology, and more specifically, to a flower column mold. Background Technology

[0002] In public places such as parks and squares, traditional stone carvings (such as the twelve zodiac animal statues) usually rely on manual carving, which is complicated, time-consuming, and costly, making it difficult to promote and apply on a large scale. To replace stone carvings, landscape columns cast in concrete have gradually been adopted. However, the existing molds used to manufacture such landscape columns have significant limitations: the landscape columns they form usually consist of two parts - the lower part is a supporting cylinder, and the upper part is a truncated cone or square that carries the decorative function. Limited by the structural design of existing molds, the weight of the upper truncated cone or square pedestal relies entirely on the vertical support provided by the lower cylinder during casting. To ensure structural stability and prevent the upper part from crushing the lower part or causing overturning, the landscape columns produced by existing molds have to have a relatively small radial dimension (i.e., width or diameter) at the top, resulting in insufficient long-distance viewing. At the same time, to match the upper load and provide sufficient support, the lower cylinder must be designed to be short and thick. This "small at the top, short and thick at the bottom" structural form determined by the mold makes the landscape columns easily obscured by surrounding trees, billboards, or other environmental objects during actual placement, severely weakening their visual expressiveness and decorative effect as landscape elements, and limiting the application of such molds in enhancing the aesthetics of public spaces. Utility Model Content

[0003] The purpose of this invention is to overcome the defects in the prior art and provide a flower column mold that can form a landscape column with a larger upper radial dimension and a more slender lower support structure, thereby significantly improving the long-distance viewing value and resistance to environmental obstruction of the landscape column.

[0004] To solve the above problems, this utility model provides a flower column mold, including two symmetrically arranged half mold shells. The two half mold shells are joined together to form a casting cavity. Each half mold shell includes an upper half mold shell and a lower half mold shell. After the pair of upper half mold shells are joined together, their inner walls form a flared opening that is larger at the top and smaller at the bottom. The inner sidewall of the flared opening is provided with a first arc-shaped arch support extending from the upper edge of the flared opening to the lower edge and gradually narrowing radially. The lower half mold shell is supported on the bottom of the upper half mold shell and is detachably connected to the upper half mold shell.

[0005] Compared with the prior art, the advantages of this utility model are as follows: By setting a first arc-shaped arch support extending from the upper edge to the lower edge of the flared opening and gradually narrowing radially on the inner wall of the flared opening, a continuous arch-bridge load-bearing skeleton is formed inside the cast body. This structure is based on the mechanical principles of arch bridges, transforming the vertical load of the upper part into radial pressure along the arch surface and distributing it to the lower part, so that the lower column is mainly subjected to axial pressure, significantly reducing the risk of bending stress. The radial load distribution mechanism and the synergistic effect of the lateral support force of the arch break through the strong coupling relationship between the upper size and the lower support strength: the lateral support force offsets the overturning moment of the large-diameter flared opening, realizing a larger radial outward opening design of the flared opening, allowing the upper part of the formed landscape column to have a larger diameter to enhance visual impact. The load distribution and transmission path optimizes the mechanical performance of the support, allowing the lower column to be designed to be more slender and avoid environmental obstruction. In addition, the hollow structure naturally formed in the arch area also reduces the amount of concrete consumed, reducing resource input while ensuring structural stability.

[0006] As an improvement, each upper half of the mold shell consists of at least two circumferentially joined first mold pieces. The inner wall of each first mold piece is provided with a second arc-shaped arch support extending circumferentially and bulging inward in the middle. With this structure, the segmented upper half mold shell design enables segmented manufacturing and convenient transportation of large components, significantly reducing processing difficulty. After casting, the second arc-shaped arch support forms a continuously bulging annular bridge arch structure around the upper flared end of the cast body. This structure converts the radial tension on the cast body into circumferential compressive stress, effectively suppressing the risk of cracking in the flared end area. The annular bridge arch structure and the first arc-shaped arch support on the inner wall of the flared end work together to form a double-arch load-bearing system, further strengthening the radial tensile capacity while dispersing the vertical load, thus improving the structural integrity of the cast body under complex working conditions.

[0007] As an improvement, each lower mold shell is constructed by splicing together the same number of second mold pieces as the first mold pieces. The inner wall of each second mold piece is provided with a third arc-shaped arch support extending circumferentially and bulging inwards at the center. Applying this structure significantly reduces the processing difficulty of large molds, enabling segmented manufacturing and transportation. After casting, the third arc-shaped arch support forms a continuously bulging annular bridge arch structure on the lower cylindrical circumference of the cast body. This structure, through the principle of arch mechanics, transforms the radial tension on the cast body into circumferential pressure and distributes it, effectively suppressing the risk of radial cracking and improving long-term service stability.

[0008] As an improvement, the outer wall of the upper mold shell is provided with multiple first vertical ribs arranged circumferentially and multiple first horizontal ribs arranged vertically. The first vertical ribs and first horizontal ribs intersect and connect to form a first grid-like reinforcing structure. The outer wall of the lower mold shell is provided with multiple second vertical ribs arranged circumferentially and multiple second horizontal ribs arranged vertically. The second vertical ribs and second horizontal ribs intersect and connect to form a second grid-like reinforcing structure. After applying this structure, the first grid-like reinforcing structure on the outer wall of the upper mold shell and the second grid-like reinforcing structure on the lower mold shell significantly improve the bending stiffness of the mold shell through bidirectional rib constraint. The circumferentially spaced vertical ribs resist radial expansion caused by casting pressure, and the vertically spaced horizontal ribs suppress axial deformation, ensuring that the mold maintains geometric accuracy during multiple uses and extending its service life.

[0009] As an improvement, the two half-mold shells are fixedly connected in an adjustable manner via a bolt and nut assembly. The two half-mold shells are symmetrically provided with multiple pairs of elongated holes and at least two pairs of round holes along their mating surfaces. The elongated holes extend vertically and are spaced apart vertically, while the round holes are spaced apart vertically and used to insert locating pins. The bolts of the bolt and nut assembly pass through the elongated holes and are tightened with the nuts. This structure addresses the problem of vertical misalignment on the mating surfaces that easily occurs when assembling large half-mold shells. The symmetrically arranged round holes, used for inserting locating pins, achieve precise vertical positioning of the two half-mold shells, ensuring the concentricity of the casting cavity. The bolts, passing through the vertical elongated holes and tightened with the nuts, compensate for assembly tolerances under the constraint of the locating pins, effectively eliminating the misalignment of the mating surfaces caused by excessively large mold dimensions and ensuring the molding accuracy of large casting bodies.

Detailed Implementation

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 , Figure 2 and Figure 7 As shown, a flower column mold includes two symmetrically arranged half-mold shells, which are joined together to form a casting cavity. Each half-mold shell includes an upper half-mold shell 1 and a lower half-mold shell 2. When the pair of upper half-mold shells 1 are joined, their inner walls form a flared opening 10 that is wider at the top and narrower at the bottom. The inner sidewall of the flared opening 10 is provided with a first arc-shaped arched support portion 31 that extends from the upper edge to the lower edge of the flared opening 10 and gradually narrows radially. The lower half-mold shell 2 is supported on the bottom of the upper half-mold shell 1 and is detachably connected to the upper half-mold shell 1. Typically, both the upper half-mold shell 1 and the lower half-mold shell 2 are provided with multiple pairs of bolt holes distributed circumferentially. The upper half-mold shell 1 and the lower half-mold shell 2 are fixedly connected by bolt and nut assemblies that pass through the bolt holes.

[0021] This embodiment forms a continuous arch-shaped load-bearing skeleton inside the cast body by setting a first arc-shaped arch support 31 extending from the upper edge to the lower edge of the flared opening 10 and gradually narrowing radially. Based on the mechanical principles of arch bridges, this structure converts the vertical load of the upper part into radial pressure along the arch surface and distributes it to the lower part, so that the lower column is mainly subjected to axial pressure, which significantly reduces the risk of bending stress. The radial load distribution mechanism and the synergistic effect of the arch lateral support force break the strong coupling relationship between the upper size and the lower support strength: the lateral support force offsets the overturning moment of the large-diameter flared opening 10, realizing a larger radial outward opening design of the flared opening 10, so that the upper part of the formed landscape column can obtain a larger diameter to enhance the visual impact. The load distribution and transmission path optimizes the mechanical performance of the support, so that the lower column can be designed to be more slender and avoid environmental obstruction. In addition, the hollow structure naturally formed in the bridge arch area also reduces the amount of concrete consumed, reducing resource input while ensuring structural stability.

[0022] like Figure 1 , Figure 3 and Figure 7As shown, each upper half of the mold shell 1 is composed of at least two first mold pieces 11 spliced ​​together circumferentially. The inner wall of each first mold piece 11 is provided with a second arc-shaped arch support 32 that extends circumferentially and bulges inward in the middle. After applying this structure, the segmented upper half of the mold shell 1 design realizes the segmented manufacturing and convenient transportation of large components, significantly reducing the processing difficulty. After casting, the second arc-shaped arch support 32 forms a continuously bulging annular bridge arch structure around the upper flared opening 10 of the casting body. This structure converts the radial tension on the casting body into circumferential compressive stress and disperses it, effectively suppressing the risk of cracking in the flared opening 10 area. The annular bridge arch structure and the first arc-shaped arch support 31 on the inner wall of the flared opening 10 work together to form a double-arch load-bearing system, which further strengthens the radial tensile capacity on the basis of dispersing the vertical load and improves the structural integrity of the casting body under complex working conditions.

[0023] like Figure 1 , Figure 4 and Figure 7 As shown, each lower mold shell 2 is constructed by splicing together second mold pieces 21 in the same number as the first mold pieces 11. The inner wall of each second mold piece 21 is provided with a third arc-shaped arch support 33 that extends circumferentially and bulges inward in the middle. After applying this structure, the segmented lower mold shell 2 design significantly reduces the processing difficulty of large molds, enabling segmented manufacturing and transportation. After casting, the third arc-shaped arch support 33 forms a continuously bulging annular bridge arch structure on the lower cylindrical circumference of the casting body. This structure converts the radial tension on the casting body into circumferential pressure and distributes it through the arch mechanical principle, effectively suppressing the risk of radial cracking and improving long-term service stability.

[0024] like Figure 6 and Figure 7 As shown, the outer wall of the upper mold shell 1 is provided with multiple first vertical ribs 41 arranged circumferentially and multiple first horizontal ribs 51 arranged vertically. The first vertical ribs 41 and the first horizontal ribs 51 are intersected and connected to form a first grid-like reinforcing structure. The outer wall of the lower mold shell 2 is provided with multiple second vertical ribs 42 arranged circumferentially and multiple second horizontal ribs 52 arranged vertically. The second vertical ribs 42 and the second horizontal ribs 52 are intersected and connected to form a second grid-like reinforcing structure. After applying this structure, the first grid-like reinforcing structure of the outer wall of the upper mold shell 1 and the second grid-like reinforcing structure of the lower mold shell 2 significantly improve the bending stiffness of the mold shell through bidirectional rib constraint. The circumferentially spaced vertical ribs resist radial expansion caused by casting pressure, and the vertically spaced horizontal ribs suppress axial deformation, ensuring that the mold maintains geometric accuracy during multiple uses and extending its service life.

[0025] like Figure 6 and Figure 7As shown, two semi-mold shells are fixedly connected vertically via a bolt and nut assembly. The two semi-mold shells are symmetrically arranged along their mating surfaces 60 with multiple pairs of elongated holes 61 and at least two pairs of round holes 62. The elongated holes 61 extend vertically and are spaced apart vertically, while the round holes 62 are spaced apart vertically and used to insert locating pins. The bolts of the bolt and nut assembly pass through the elongated holes 61 and are tightened with the nuts. This structure addresses the problem of vertical misalignment of the mating surfaces 60 that easily occurs when assembling large semi-mold shells. The symmetrically arranged round holes 62, through which locating pins are inserted, achieve precise vertical positioning of the two semi-mold shells, ensuring the concentricity of the casting cavity. The bolts pass through the vertical elongated holes 61 and are tightened with the nuts, compensating for assembly tolerances under the constraint of the locating pins. This effectively eliminates the misalignment of the mating surfaces caused by excessively large mold dimensions, ensuring the molding accuracy of large casting bodies.
