Description

Technical Field

[0001] This utility model relates to the field of mold cooling technology, and in particular to a cooling structure for wax molds. Background Technology

[0002] In the field of modern precision casting, the wax pattern mold is a key component in the lost-wax casting process, and its cooling efficiency directly affects the molding quality and production efficiency of the wax pattern. Rapid and uniform cooling can effectively reduce the shrinkage and deformation of the wax pattern, improve dimensional accuracy, and shorten the production cycle, meeting the needs of industries such as aerospace and medical devices for high-precision, high-volume wax pattern production.

[0003] In existing technologies, wax mold cooling structures mostly employ a single cooling method, such as traditional water-cooled pipes or air-cooled heat dissipation. Water-cooled pipes typically involve creating simple, straight flow channels inside the mold, utilizing the circulation of coolant to remove heat. Air-cooled heat dissipation involves installing heat sinks on the outside of the mold, supplemented by natural convection or low-speed fans. These mechanical structures are simple in design, relying on basic heat conduction and convection heat transfer principles, and lack targeted optimization for the complex thermal field distribution of the mold.

[0004] However, with the increasing application of complex, long wax mold parts in precision casting, existing cooling structures have revealed significant shortcomings. A single cooling method cannot handle the high heat load caused by the large surface area and volume of long wax molds, leading to a substantial increase in cooling time. This not only slows down the overall production pace, causing casting equipment to operate inefficiently for extended periods, but also severely prolongs the production cycle, failing to meet market demands for rapid delivery. This has become a bottleneck restricting efficient production in the precision casting industry. Therefore, a wax mold cooling structure is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a wax mold cooling structure, which aims to improve the problem of increased wax mold cooling time in the prior art, which slows down the overall production rhythm and leads to a longer production cycle.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cooling structure for a wax mold includes a top plate and a second connecting plate. The sidewall of the second connecting plate is disposed on the sidewall of the top plate. An inlet pipe is fixedly connected inside the top plate. A first fixing column is fixedly connected to the sidewall of the top plate. A first template and a second template are slidably connected to the outer wall of the first fixing column. A base is slidably connected to one end of the first fixing column. A first connecting plate is fixedly connected to the sidewall of the base. A cooling component is disposed on the sidewall of the first template.

[0008] The cooling assembly includes heat dissipation fins, circulating water pipes, and a fan. The sidewalls of the heat dissipation fins are fixedly connected to the sidewalls of the first template, the outer walls of the circulating water pipes are fixedly connected to the inside of the second template, and the outer walls of the fan are fixedly connected to the inside of the first connecting plate.

[0009] As a further description of the above technical solution:

[0010] The base sidewall is fixedly connected to a second fixing column, which is internally slidably connected to the first connecting plate.

[0011] As a further description of the above technical solution:

[0012] The outer wall of the second fixed column is provided with a spring, one end of which is fixedly connected to the inner wall of the base, and the other end of which is fixedly connected to the side wall of the first connecting plate.

[0013] As a further description of the above technical solution:

[0014] A hydraulic cylinder is fixedly connected to the side wall of the second connecting plate, and a bolt is fixedly connected to the output end of the hydraulic cylinder.

[0015] As a further description of the above technical solution:

[0016] The outer wall of the bolt is rotatably connected to a first rotating plate, and the side wall of the first rotating plate is rotatably connected to the inner wall of the base.

[0017] As a further description of the above technical solution:

[0018] The first rotating plate sidewall is slidably connected to the inside of the base, and the first rotating plate sidewall is rotatably connected to the sidewall of the hydraulic cylinder.

[0019] As a further description of the above technical solution:

[0020] A fixing plate is fixedly connected to the side wall of the hydraulic cylinder, and a second rotating plate is rotatably connected to the side wall of the fixing plate.

[0021] As a further description of the above technical solution:

[0022] The second rotating plate sidewall is rotatably connected to the first rotating plate sidewall, and the second rotating plate sidewall is rotatably connected to the hydraulic cylinder sidewall.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, air cooling is generated by a fan, and then the fan acts on the side wall of the heat dissipation fins to cool down the first template. At the same time, water is circulated through the circulating water pipe to reduce the temperature of the first template, achieving a highly efficient cooling effect. This solves the problem of increased cooling time for long wax molds, which slows down the overall production rhythm and leads to a longer production cycle, and improves the practicality of the wax mold cooling structure.

[0025] 2. In this utility model, the bolt is driven to move by the output end of the hydraulic cylinder. The movement of the bolt will drive the first rotating plate on the outer wall to rotate. At the same time, the first rotating plate will be limited by the second rotating plate and the fixed plate during the rotation, changing the linear motion into the circular motion. This achieves the effect of quickly disassembling the mold, solves the problem of wax residue, difficulty in thorough cleaning if the cooling structure is fixed, and long-term accumulation of wax residue that contaminates the new wax pattern, and improves the stability of the wax pattern mold cooling structure.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 An embodiment of this utility model provides a wax mold cooling structure, including a top plate 1 and a second connecting plate 6. The side wall of the second connecting plate 6 is disposed on the side wall of the top plate 1. An inlet pipe 14 is fixedly connected inside the top plate 1. A first fixing column 11 is fixedly connected to the side wall of the top plate 1. A first template 2 and a second template 3 are slidably connected to the outer wall of the first fixing column 11. A base 5 is slidably connected to one end of the first fixing column 11. A first connecting plate 4 is fixedly connected to the side wall of the base 5. A cooling component is disposed on the side wall of the first template 2.

[0035] The cooling assembly includes heat dissipation fins 12, circulating water pipes 15, and a fan 13. The fan 13 generates airflow and directs it to the heat dissipation fin array 12 on the side wall of the first template 2. By using forced convection, the heat exchange efficiency of the heat dissipation fins 12 is further improved, enhancing the cooling effect of the entire cooling assembly. This allows the template temperature to drop rapidly below the solidification point of the wax, effectively shortening the cooling time of the wax model. The side wall of the heat dissipation fins 12 is fixedly connected to the side wall of the first template 2. The outer wall of the circulating water pipe 15 is fixedly connected to the inside of the second template 3. The outer wall of the fan 13 is fixedly connected to the inside of the first connecting plate 4. The circulating water pipe 15 forms a closed-loop flow channel inside the second template 3. In conjunction with the circulating water pump, it drives the coolant flow, directly removing heat from the template and effectively cooling the second template 3. This provides a uniform and rapid cooling environment for the wax model, ensuring its quality.

[0036] Reference Figure 1 , Figure 4 and Figure 5A second fixing column 17 is fixedly connected to the side wall of the base 5. The second fixing column 17 is slidably connected to the inside of the first connecting plate 4. A spring 18 is provided on the outer wall of the second fixing column 17. One end of the spring 18 is fixedly connected to the inner wall of the base 5, and the other end of the spring 18 is fixedly connected to the side wall of the first connecting plate 4. A hydraulic cylinder 7 is fixedly connected to the side wall of the second connecting plate 6. The hydraulic cylinder 7, bolt 16, first rotating plate 8, fixing plate 9, and second rotating plate 10 cooperate with each other to perform motion conversion, thereby realizing the rapid disassembly of the mold. This design greatly facilitates the cleaning and maintenance of the mold, effectively prevents wax residue from contaminating new wax patterns, ensures the practicality and stability of the mold cooling structure, and guarantees efficient and continuous production. The output end of the hydraulic cylinder 7 is fixedly connected to a bolt 16, the outer wall of the bolt 16 is rotatably connected to a first rotating plate 8, the side wall of the first rotating plate 8 is rotatably connected to the inner wall of the base 5, the side wall of the first rotating plate 8 is slidably connected to the inside of the base 5, the side wall of the first rotating plate 8 is rotatably connected to the side wall of the hydraulic cylinder 7, the side wall of the hydraulic cylinder 7 is fixedly connected to a fixed plate 9, the side wall of the fixed plate 9 is rotatably connected to a second rotating plate 10, the side wall of the second rotating plate 10 is rotatably connected to the side wall of the first rotating plate 8, and the side wall of the second rotating plate 10 is rotatably connected to the side wall of the hydraulic cylinder 7.

[0037] Working principle: During the cooling phase, the system simultaneously activates both air-cooled and water-cooled modules: a circulating water pump drives the coolant through the circulating water pipe 15 embedded inside the second template 3 to form a closed-loop flow, directly removing heat from the template; the synchronously operating fan 13 directs airflow to the heat dissipation fin array 12 on the side wall of the first template 2, significantly improving heat exchange efficiency by increasing the heat dissipation surface area and forced convection. This composite cooling mode allows the template temperature to drop rapidly below the wax solidification point, and tests have shown that it improves cooling efficiency compared to the traditional single-mode cooling.

[0038] When the mold needs to be disassembled for cleaning and maintenance, the output end of the hydraulic cylinder 7 drives the bolt 16 to move linearly, which in turn drives the first rotating plate 8 on the outer wall to rotate. During the rotation, the limiting structure formed by the second rotating plate 10 and the fixed plate 9 converts the linear motion of the bolt 16 into circumferential motion, thereby realizing the rapid disassembly of the mold. This design not only facilitates the cleaning of residual wax, but also prevents wax residue from contaminating the new wax model, effectively improving the practicality and stability of the mold cooling structure and ensuring efficient and continuous production.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
