Technical Field

[0001] This utility model relates to the field of high-temperature alloy casting, and in particular to a high-temperature resistant composite mold for casting iron alloy blocks. Background Technology

[0002] In the field of high-temperature alloy processing, traditional casting methods for high-temperature alloys (such as ferrosilicon, silicomanganese, metallic silicon, high-carbon ferrochrome, and silicon-chromium) involve casting molten metal into large blocks, which are then manually crushed for reuse, resulting in a secondary waste of human resources and increasing development costs. With technological advancements, molten metal can now be directly cast into several smaller blocks using molds, and then demolded using ejector pins.

[0003] Chinese patent publication number CN112846154B, entitled "A High-Temperature Casting Continuous Demolding Combined Equipment," describes a process where castings are formed within a mold body before demolding. However, the mold body is a single piece, resulting in a short mold lifespan, significant waste, and high replacement costs. Utility Model Content

[0004] To address the above problems, this utility model provides a high-temperature resistant composite mold for casting iron alloy blocks that is simple in structure, easy to replace, and reduces costs.

Detailed Implementation

[0017] This utility model is as follows Figure 1-12 As shown, a high-temperature resistant composite mold for casting iron alloy blocks includes a mold body 1. The mold body is provided with a plurality of mold cavities 11 and a plurality of through holes 12. The mold cavities and through holes correspond one-to-one and are connected. The mold cavities are used to form castings. The mold body 1 includes an upper mold body 2 and a lower mold body 3. The mold cavity 11 is located inside the upper mold body 2, and the through hole 12 is located inside the lower mold body 3. The upper mold 2 is detachably connected to the lower mold 3.

[0018] In operation, this invention combines an upper mold body and a lower mold body. Therefore, if the mold body is damaged, only one component needs to be replaced, rather than the entire mold assembly. This invention saves costs and time, conserves mold materials, and improves economic efficiency.

[0019] In particular, even if the upper mold body deforms when it comes into contact with high-temperature molten alloy, it will not affect the lower mold body.

[0020] The mold body 1 has upward-facing protruding edges 4 at both ends.

[0021] The protruding edges at both ends of the mold body serve to block the molten alloy, preventing it from overflowing from the mold body and causing damage to the equipment (such as the connection between the mold and the chain), thereby improving the service life of the equipment and the reliability of production safety.

[0022] like Figure 1 As shown, the upper mold 1 is plate-shaped, the lower mold 2 is U-shaped, and the upper mold is located inside the U-shaped opening of the lower mold.

[0023] The plate-shaped upper mold body is directly connected to the U-shaped opening of the lower mold body, which facilitates positioning and connection.

[0024] like Figure 4 , 7 As shown, the upper mold 1 is U-shaped, the lower mold 2 is U-shaped, the upper mold is located inside the U-shaped opening of the lower mold, and the top of the upper mold is higher than the top of the lower mold.

[0025] Both the upper and lower mold bodies are U-shaped for easy positioning and connection. At this point, the two ends of the upper mold body form protruding edges, serving to protect the equipment.

[0026] like Figure 4 The middle and lower parts of the mold are U-shaped as a whole, such as Figure 7 In the middle, the two ends of the lower mold body are provided with lugs 7, thus forming a U-shape, and are connected to the upper mold body through the lugs 7.

[0027] The upper mold body 2 and the lower mold body 3 are respectively provided with corresponding threaded holes 5, which are used to connect studs.

[0028] By setting corresponding threaded holes, the upper and lower mold bodies can be connected by studs, making installation convenient.

[0029] The threaded hole 5 is arranged in a horizontal and / or vertical direction; In the vertical direction, the threaded holes of the upper mold body are arranged from bottom to top and are in the form of blind holes; In the horizontal direction, the threaded holes of the upper mold body are arranged from the outside to the inside, and are in the form of blind holes.

[0030] When connecting the upper mold body and the lower mold body, studs can be used in the horizontal and / or vertical directions according to processing requirements; In the vertical direction, the stud penetrates the lower mold body from the bottom and connects to the blind hole in the upper mold body. The blind hole is designed to prevent the high-temperature alloy liquid from contacting the stud and causing damage to the connection.

[0031] The cross-section of the mold cavity 12 is semi-circular, circular, rhomboid, rectangular, square, triangular, or polygonal.

[0032] The mold cavity can be designed in different shapes to meet the shape requirements of the casting being processed. For example, a circular cavity can be designed as a cylinder or a frustum. However, in actual production, it is not limited to these shapes.

[0033] The upper mold body 2 is made of any one of the following materials: carbon-carbon composite material, silicon carbide graphite composite material, boron carbide graphite composite material, alumina-zirconia composite material, chromium zirconium copper C18150, tungsten copper alloy, CuNi2SiCr alloy, CuCo2Be alloy, CuNi25 cupronickel, CuNi10 copper-nickel alloy, BAI13-3 copper alloy, C95300 copper-aluminum alloy, T1 pure copper, T2 pure copper, oxygen-free copper TU1, and TU2.

[0034] By selecting materials for the upper mold body, different processing requirements can be met, and the cost of replacing the entire mold can be saved.

[0035] The material of the lower mold body 3 is any one of the following: carbon-carbon composite material, silicon carbide graphite composite material, boron carbide graphite composite material, alumina-zirconia composite material, chromium zirconium copper C18150, tungsten copper alloy, CuNi2SiCr alloy, CuCo2Be alloy, CuNi25 cupronickel, CuNi10 copper-nickel alloy, BAI13-3 copper alloy, C95300 copper-aluminum alloy, T1 pure copper, T2 pure copper, oxygen-free copper TU1, TU2, heat-resistant alloy steel, and heat-resistant cast iron.

[0036] By selecting materials for the lower mold body, different processing requirements can be met, and the cost of replacing the entire mold can be saved.

[0037] The combination of the upper and lower mold bodies offers convenience, flexibility, and wide adaptability.

[0038] It also includes a limiting tie rod 6, and the bottom of the lower mold body is provided with a T-shaped groove 30. The end of the limiting rod is T-shaped and is connected to the T-shaped groove.

[0039] This design facilitates the connection between the limit rod and the lower mold body, making assembly and disassembly easier. The original threaded connection has been improved to prevent loosening due to thermal expansion and contraction of the lower mold body, thus enhancing connection reliability and safety.

[0040] like Figure 11-12 As shown, a spring is sleeved on the limit rod. The operating principle of the initial state and the demolding state is the same as that in patent CN202110049570.X, entitled "A High Temperature Casting Continuous Demolding Combination Equipment", which will not be repeated here.

[0041] Regarding the information disclosed in this case, the following points need to be clarified: (1) The accompanying drawings of the embodiments disclosed in this case only involve the structures involved in the embodiments disclosed in this case; other structures can refer to the general design. (2) Where there is no conflict, the embodiments and features disclosed in this case can be combined with each other to obtain new embodiments; The above are merely specific embodiments disclosed in this case, but the scope of protection of this disclosure is not limited thereto. The scope of protection disclosed in this case shall be determined by the scope of protection of the claims.
