Description

Technical Field

[0001] This invention relates to the field of ship component casting technology, and in particular to a rapid cooling device for precision alloy castings. Background Technology

[0002] High-tech ships refer to vessels that utilize advanced ship design and manufacturing technologies, possessing characteristics such as high performance, high reliability, and low energy consumption. Pipeline valves, as key components in high-tech ships, directly impact the ship's safe operation and performance. Pipeline valve shells are typically manufactured using casting processes, and the cooling process is a crucial step in this process; the quality of cooling directly affects the mechanical properties, dimensional accuracy, and surface quality of the casting.

[0003] A search revealed Chinese invention patent publication number CN121267156B, entitled "A High-Tech Shipbuilding Pipe Valve Shell Casting Cooling Device." This invention relates to the field of shipbuilding component casting technology and includes a cooling box. Inside the cooling box is a pipe valve shell body, and within the cooling box is a steering and repositioning mechanism for the pipe valve shell body to rotate 180 degrees. This high-tech shipbuilding pipe valve shell casting cooling device, through the steering and repositioning mechanism, achieves automated 180-degree reciprocating rotation of the valve shell in the coolant. By periodically changing the tilt angle of the valve shell, the high-temperature coolant quickly detaches from the valve shell surface and mixes with the surrounding low-temperature coolant. Simultaneously, new low-temperature coolant continuously replenishes the cooling contact surface, preventing the formation of a "thermal barrier." Furthermore, the continuous swinging and turning of the valve shell accelerates the flow of coolant across the surface and inner wall of the valve shell, improving cooling efficiency.

[0004] Traditional casting cooling devices rely on manual positioning or simple fixtures. Mold positioning deviations can lead to uneven contact between the coolant and the casting, and even localized cooling dead zones, severely affecting the dimensional accuracy and microstructure uniformity of precision castings. Traditional cooling devices often have a split shell structure with gaps at the joints, making it easy for coolant to leak under pressure. This not only wastes coolant and pollutes the environment, but also causes unstable pressure in the cooling chamber. Furthermore, traditional cooling devices often use disposable coolant discharge, which cannot be recycled, resulting in significant resource waste. At the same time, the heat from the casting is directly discharged with the coolant without being recovered, leading to a large loss of heat energy. This not only increases cooling costs but also fails to meet the requirements of green manufacturing.

[0005] Therefore, the existing rapid cooling device for precision alloy castings cannot meet the needs of practical use, so there is an urgent need for improved technology to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a rapid cooling device for precision alloy castings, which solves the problems mentioned in the background art.

[0011] Preferably, the placement structure includes sliders symmetrically slidably connected to the upper end of the sliding frame, a rotating rod passing through the slider and threadedly connected, a placement plate fixedly connected to the upper end of the slider, and an installation groove provided on an adjacent side between the two placement plates.

[0012] Preferably, the positioning structure includes a positioning block fixedly connected to the middle of the upper part of the base plate, positioning pins that match the positioning holes are symmetrically fixedly connected to the left and right ends of the positioning block, and adjustment holes are symmetrically fixedly connected to the upper part of the base plate with the positioning block as the center point.

[0013] Preferably, the heat dissipation structure includes a housing fixedly connected to the upper end of the placement plate, with flow channels evenly distributed in the inner cavity of the housing, and a connector that matches the flow channels evenly fixedly connected to the upper part of the housing on the right side, the outer radius of the connector being the same as the inner radius of the flow channels.

[0014] Preferably, the storage structure includes storage boxes symmetrically and fixedly connected to the lower end of the base plate, heat dissipation plates are uniformly and fixedly connected to the outer surface of the storage boxes, and reflux pipes are symmetrically and rotatably connected between the two heat dissipation plates, and the two storage boxes are interconnected through the reflux pipes.

[0015] Preferably, the transmission structure includes a transmission pipe connected to the middle of one side of the storage box, a transmission pump fixedly connected to the end of the transmission pipe away from the storage box, a lifting plate fixedly connected above the transmission pump, a transmission tube matching the transmission pump fixedly connected to the upper surface of the lifting plate, the transmission tube being slidably connected to the inner cavity of the adjustment hole, the lifting plate being slidably connected to the bottom plate through the lifting structure, and a through groove matching the transmission tube being symmetrically opened on the lower end of the placement plate, the through groove being interconnected with the flow pipe.

[0016] Preferably, the lifting structure includes a lifting toothed plate symmetrically fixedly connected to the middle of the lower end of the base plate. The lifting toothed plate passes through the lifting plate and is slidably connected. A rotating frame is fixedly connected to the lower end face of the lifting plate on both sides of the lifting toothed plate. Adjusting gears are symmetrically rotatably connected to the inner cavity of the rotating frame. The two adjusting gears mesh with the lifting toothed plates on both sides respectively. A lifting drive structure is provided in the middle of the inner cavity of the rotating frame.

[0017] Preferably, the lifting drive structure includes a lifting gear rotatably connected to the middle of the inner cavity of the rotating frame. The lifting gear meshes with the adjusting gear. A lifting motor is fixedly connected to one side of the lower middle part of the transmission pipe. The rotating shaft of the lifting gear near the lifting motor passes through the rotating frame and is fixedly connected to the output end of the lifting motor. The lifting motor is specifically a micro motor.

[0018] The present invention has the following beneficial effects:

[0019] 1. This invention uses a drive motor to rotate a drive gear, which in turn drives a synchronous toothed belt, transmission gears, and a rotating rod to rotate synchronously. This causes the two side sliders to move closer together, allowing the placement plate to precisely engage with the positioning structure through the mounting groove and positioning hole. Simultaneously, the two side housings are spliced ​​together via insertion pipes, achieving precise positioning of the casting mold within the housing cavity and ensuring complete fit with the housing. This linkage structure ensures stable mold clamping without displacement, avoiding casting dimensional deviations caused by mold shaking during cooling. It also eliminates the gap between the mold and the housing, preventing the loss of cooling medium and laying the foundation for uniform cooling. This effectively reduces the scrap rate of precision castings due to positioning deviations. A lifting motor drives a lifting gear, which, through the meshing of the lifting gear and adjusting gear, drives a lifting gear plate to raise and lower the transmission pipe and transmission insertion pipe, ensuring the transmission insertion pipe precisely engages within the slot of the placement plate, achieving automatic and precise docking of the cooling pipeline. Compared to manual docking, this linkage structure offers high transmission precision and controllable stroke. It not only avoids errors caused by manual docking but also enhances pipeline sealing through a snap-fit ​​connection, preventing coolant leakage. This reduces coolant consumption and prevents leakage from corroding molds, castings, and equipment, ensuring a clean production environment. Furthermore, the pipeline height can be flexibly adjusted according to the mold height, adapting to precision casting molds of different specifications and thicknesses, thus expanding the applicability of the device.

[0020] 2. This invention utilizes a transmission structure in conjunction with dual storage tanks, flow pipes, and return pipes to form a closed-loop coolant circulation system: coolant in one storage tank is pumped through a transmission pump, transmission pipe, and transmission insert into the flow pipe of the housing, where it fully contacts the mold and absorbs heat from the casting. After heat absorption, the coolant is transported by the transmission structure on the other side to another storage tank. After cooling down by the heat dissipation plate on the outer surface of the storage tank, it flows back to the supply storage tank through the return pipe, achieving coolant recycling. This closed-loop circulation design allows the coolant to continuously remove heat from the casting, significantly shortening the cooling cycle of precision castings and improving production speed. Simultaneously, the flow pipes are fully fitted to the mold, ensuring uniform heating and synchronous heat absorption in all parts of the casting, avoiding defects such as shrinkage cavities, cracks, and stress deformation caused by localized rapid or slow cooling, thus guaranteeing the forming accuracy and mechanical properties of the precision casting. From mold positioning and clamping, housing splicing and sealing, to cooling pipe connection and cooling... Liquid circulation cooling is employed, with the entire process completed through automated linkage of various structures. This eliminates the need for manual handling, alignment, pipe connection, and clamping, significantly reducing labor costs and minimizing errors caused by manual operation, thus improving production stability. Furthermore, the mold cooling process is entirely enclosed within the shell cavity, preventing operators from close contact with high-temperature molds and castings, effectively avoiding burns and heat radiation hazards, and enhancing operational safety. The device's transmission structure (drive gears, synchronous belts, transmission gears, etc.), cooling pipes, and storage tank all adopt a modular layout, with each component relatively independent. The transmission components utilize standardized mechanical structures, facilitating easy disassembly, replacement, and repair after wear, eliminating the need for complete equipment disassembly, shortening downtime for maintenance, and reducing maintenance costs. The storage tank and transmission pipes are independently laid out, allowing for individual troubleshooting without affecting overall equipment operation, thus improving the device's operational stability and lifespan.

A transmission structure 8 is provided between the two storage structures 7 and the transmission structure 8. A lifting structure 9 is fixedly connected to the middle of the lower end of the base plate 1.

[0034] Furthermore, the sliding structure 2 includes a sliding frame 21 symmetrically fixedly connected to the upper end of the base plate 1. A rotating rod 22 is rotatably connected to the inner cavity of the sliding frame 21. Two threads with opposite directions are opened on the outer surface of the rotating rod 22. A transmission gear 23 is rotatably connected to one side of the sliding frame 21. The rotating shaft of the rotating rod 22 near the transmission gear 23 passes through the sliding frame 21 and is fixedly connected to the transmission gear 23. Through the sliding structure 2 on the base plate 1, the placement structure 4 is installed and placed during use, and the direction and distance of movement of the placement structure 4 are adjusted by rotating the rotating rod 22.

[0035] Furthermore, the drive structure 3 includes a synchronous toothed belt 31 that is connected to the outer surface of the two transmission gears 23. A drive gear 32 is meshed in the middle of the inner cavity of the synchronous toothed belt 31. A drive motor 33 is fixedly connected to the lower middle part of the base plate 1 near the transmission gear 23. The output end of the drive motor 33 is fixedly connected to the drive gear 32. Through the drive structure 3 on the base plate 1, the synchronous toothed belt 31 is linked with the transmission gear 23 during use to drive the slider 41 to move linearly, thereby achieving precise engagement between the placement plate 42 and the positioning structure 5, reducing manual adjustment errors, ensuring the repeatability of the casting mold positioning accuracy, and improving the consistency of batch processing.

[0036] Furthermore, the placement structure 4 includes a slider 41 symmetrically slidably connected to the upper end of the sliding frame 21. A rotating rod 22 passes through the slider 41 and is threadedly connected. A placement plate 42 is fixedly connected to the upper end of the slider 41. An installation groove 43 is provided on each adjacent side between the two placement plates 42. The inner cavity of the installation groove 43 is provided with positioning holes 44 symmetrically provided on the adjacent side of the two placement plates 42. The heat dissipation structure 6 is installed and placed in use through the placement structure 4 on the sliding structure 2, and the coolant is then transferred through the through groove on the placement plate 42.

[0037] Furthermore, the positioning structure 5 includes a positioning block 51 fixedly connected to the middle of the upper end of the base plate 1. The left and right ends of the positioning block 51 are symmetrically fixedly connected with positioning pins 52 that match the positioning holes 44. The upper end of the base plate 1 is symmetrically fixedly connected with adjustment holes 53 with the positioning block 51 as the center point. Through the positioning structure 5 on the base plate 1, the casting mold and casting are positioned and placed during use, and the conveying of the transmission structure 8 is adjusted through the adjustment holes 53.

[0038] Furthermore, the heat dissipation structure 6 includes a housing 61 fixedly connected to the upper end of the placement plate 42. The inner cavity of the housing 61 is evenly provided with flow pipes 62. The upper part of the right housing 61 is evenly fixedly connected with a plug pipe 63 that matches the flow pipes 62. The outer radius of the plug pipe 63 is the same as the inner radius of the flow pipes 62. Through the heat dissipation structure 6 on the placement structure 4, the two housings 61 are automatically axially aligned when the slider 41 is closed by the tapered guide design of the plug pipe 63 during use. Combined with the elastic buckle, a seamless splicing is achieved to form a sealed cooling cavity, which avoids coolant leakage and reduces the thermal resistance caused by air gaps, thereby improving the heat conduction efficiency.

[0039] Furthermore, the storage structure 7 includes storage boxes 71 symmetrically and fixedly connected to the lower end of the base plate 1. Heat dissipation plates 72 are uniformly and fixedly connected to the outer surface of the storage boxes 71. A return pipe 73 is symmetrically and rotatably connected between the two heat dissipation plates 72. The two storage boxes 71 are interconnected through the return pipe 73. Through the storage structure 7 on the base plate 1, the coolant is classified and stored according to temperature, and then the coolant in the inner cavity of the storage box 71 is quickly cooled by the heat dissipation plates 72.

[0040] Furthermore, the transmission structure 8 includes a transmission pipe 81 connected to the middle of one side of the storage box 71. A transmission pump 82 is fixedly connected to the end of the transmission pipe 81 away from the storage box 71. A lifting plate 83 is fixedly connected above the transmission pump 82. A transmission tube 84 matching the transmission pump 82 is fixedly connected to the upper end face of the lifting plate 83. The transmission tube 84 is slidably connected to the inner cavity of the adjustment hole 53. The lifting plate 83 is slidably connected to the bottom plate 1 through the lifting structure 9. A through groove matching the transmission tube 84 is symmetrically opened on the lower end face of the placement plate 42. The through groove is connected to the flow pipe 62. Through the transmission structure 8 below the bottom plate 1, the coolant in the inner cavity of the storage box 71 is transmitted to the inner cavity of the flow pipe 62 by the transmission pump 82 during use. Then, through the cooperation of the two transmission tubes 84 and the transmission pump 82 in the storage structure 7, the coolant forms a flow loop in the inner cavity of the heat dissipation structure 6.

[0041] Furthermore, the lifting structure 9 includes a lifting toothed plate 91 symmetrically fixedly connected to the lower middle part of the base plate 1. The lifting toothed plate 91 passes through the lifting plate 83 and is slidably connected. The lower end face of the lifting plate 83 is fixedly connected to the two sides of the lifting toothed plate 91. The inner cavity of the rotating frame 92 is symmetrically rotatably connected to the adjusting gear 93. The two adjusting gears 93 mesh with the lifting toothed plates 91 on both sides respectively. The middle part of the inner cavity of the rotating frame 92 is provided with a lifting drive structure 10. Through the lifting structure 9 at the lower end of the base plate 1, the relative height between the lifting plate 83 and the transmission tube 84 is adjusted in use with the cooperation of the lifting drive structure 10.

[0042] Furthermore, the lifting drive structure 10 includes a lifting gear 101 rotatably connected to the middle of the inner cavity of the rotating frame 92. The lifting gear 101 meshes with the adjusting gear 93. A lifting motor 102 is fixedly connected to one side of the lower middle part of the transmission pipe 81. The shaft of the lifting gear 101 near the lifting motor 102 passes through the rotating frame 92 and is fixedly connected to the output end of the lifting motor 102. The lifting motor 102 is specifically a micro motor. Through the lifting drive structure 10 on the transmission structure 8, the transmission pipe 81 is driven to move vertically through the three-stage transmission of the lifting gear 101, the adjusting gear 93, and the lifting gear plate 91, thereby achieving non-contact alignment between the transmission tube 84 and the mold through slot, reducing mechanical wear, and extending the component life.

[0043] Working principle:

[0044] During operation, the casting mold is placed above the positioning block 51. At this time, the drive structure 3 is activated, causing the output end of the drive motor 33 to rotate. As a result, the drive gear 32 rotates. Since the drive gear 32 is located in the inner cavity of the synchronous toothed belt 31, the synchronous toothed belt 31 rotates, which further causes the transmission gear 23 and the rotating rod 22 to rotate.

[0045] At this time, by rotating the rotating rod 22, the two sliders 41 on both sides move closer to each other. Therefore, the placement plate 42 engages with the positioning hole 44 and the positioning structure 5 through the mounting groove 43, and further makes the two shells 61 spliced ​​together through the insertion pipe 63. Thus, the casting mold is located in the inner cavity of the shell 61 and fits against the shell 61.

[0046] When the lifting drive structure 10 is activated, the output end of the lifting motor 102 rotates, so the lifting gear 101 rotates. Since the lifting gear 101 meshes with the adjusting gear 93, the adjusting gear 93 rotates. At this time, the adjusting gear 93 meshes with the lifting gear plate 91, causing the transmission tube 81 to rise in height. Therefore, the transmission tube 84 is engaged with the through groove on the placement plate 42 through the placement structure 4.

[0047] The transfer pump 82 is further activated, so that the coolant in the inner cavity of the storage tank 71 on one side is transferred through the transfer pipe 81. After being transported by the transfer pump 82 and the transfer pipe 84, it enters the inner cavity of the flow pipe 62. At this time, the heat of the casting is absorbed by the coolant in the inner cavity of the flow pipe 62, so as to achieve rapid cooling of the casting mold.

[0048] At the same time, the other side of the transmission structure 8 is activated, so that the coolant after absorbing heat is transmitted through the transmission pipe 84, the transmission pump 82 and the transmission pipe 81 to the inner cavity of the storage tank 71 on the other side. At this time, the coolant after absorbing heat is dissipated through the heat dissipation plate 72 on the outer surface of the storage tank 71. When the heat dissipation is completed, the coolant is transmitted to the other storage tank 71 through the return pipe 73, thus realizing the rapid cooling of the casting.
