Description

Technical Field

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

[0002] High-temperature alloys are mainly used in important fields such as aero engines and gas turbines. Their production process is complex and technically challenging, resulting in a low yield of high-performance high-temperature alloy castings in actual production.

[0003] In the field of mold technology, numerous researchers have continuously explored and innovated to improve the production efficiency and quality of high-temperature alloy castings. For example, the prior art, authorized by publication number CN 219425586 U, describes a mold for producing high-temperature alloy bars. This mold features a cooling cavity on its body, an insulating riser assembly, and a cooling component. The cooling component includes: a cooling fan located at the bottom of the mold body; a flow guide sleeve located inside the cooling cavity; and a flow guide port located on the side wall of the flow guide sleeve near the interior of the mold body. This invention improves the overall cooling efficiency during bar production by creating a cooling cavity and a cooling component on the mold body. The flow guide port's internal diameter gradually decreases from bottom to top to ensure upward airflow. The spiral-shaped flow guide sleeve within the cooling cavity ensures that the cold air effectively cools the high-temperature material inside the mold body.

[0004] The mold still has certain defects in practical applications. In the bar feeding stage, an air pump is used to inflate the bottom of the moving plate, pushing the moving plate to lift the bar for feeding. However, due to the lack of an effective limiting structure, it is impossible to accurately control the rising height of the moving plate. This can lead to situations where the moving plate rises too high or too low in actual operation. If it rises too high, the bar is prone to deviation and collision during ejection, affecting the dimensional accuracy and surface quality of the product, and even causing the product to be scrapped. If it rises too low, the bar cannot be completely ejected, requiring manual assistance, which not only reduces feeding efficiency but also increases labor intensity and production costs.

[0005] Therefore, it is necessary to provide a high-temperature alloy casting mold to solve the above-mentioned technical problems. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] First Embodiment

[0027] Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a high-temperature alloy casting mold provided by this utility model; Figure 2 for Figure 1 The diagram shows a cross-sectional view of the mold body. Figure 3 for Figure 2 The diagram shows a cross-sectional view of the sealed chamber. A high-temperature alloy casting mold includes: a mold body 1, a limiting block 11 fixedly installed on the bottom of the inner side of the mold body 1, and a movable plate 12 provided on the top of the limiting block 11;

[0028] Base 3, which is fixedly installed on the bottom of the mold body 1;

[0029] A sealed chamber 5 is fixedly installed on the top of the inner side of the base 3, and an air pump 4 is fixedly installed on one side of the sealed chamber 5.

[0030] A limiting component 6 is disposed on the inner side of the sealed chamber 5. The limiting component 6 includes a mounting base 61, a rotating shaft 62, a torsion spring 63, a winding wheel 64, and a pull rope 65. The mounting base 61 is fixedly installed on the inner side of the sealed chamber 5. The rotating shaft 62 is rotatably connected to the outer side of the mounting base 61. The winding wheel 64 is fixedly installed on the outer side of the rotating shaft 62. The torsion spring 63 is respectively sleeved on both ends of the outer side of the rotating shaft 62. The top of the pull rope 65 is fixedly installed on the bottom of the moving plate 12, and the bottom end of the pull rope 65 is wound around the outer side of the winding wheel 64.

[0031] One end of the torsion spring 63 is fixedly installed on the side of the rotating shaft 62, and the other end of the torsion spring 63 is fixedly installed on the inner side of the mounting base 61.

[0032] A cooling fan 31 is fixedly installed on the inner side of the base 3, and a spiral cooling pipe 32 is fixedly installed at the output end of the cooling fan 31. The spiral cooling pipe 32 is located inside the mold body 1.

[0033] The top of the mold body 1 is provided with a heat-insulating riser assembly 2.

[0034] The cooling fan 31 is fixedly installed on the inner side of the base 3. The spiral cooling pipe 32 connected to its output end is spirally wound inside the mold body 1. During the casting process, the high-temperature alloy liquid will release a large amount of heat after being injected into the mold. The cooling fan 31 is started to continuously send cold air into the spiral cooling pipe 32. The spiral cooling pipe 32 increases the contact area and contact time between the cold air and the high-temperature area inside the mold, so that the cold air can absorb heat more efficiently, thereby accelerating the cooling and solidification process of the high-temperature alloy liquid, greatly improving production efficiency, and also helping to improve the internal structure and performance of the casting, and improve product quality.

[0035] An inspection door is provided on the front of the base 3 to facilitate the maintenance of the internal components, and a sealed door is also provided on the front of the sealed compartment 5 to facilitate the maintenance of the internal components by the staff.

[0036] The air pump 4 generates a pressure difference by inflating the sealed chamber 5, which pushes the movable plate 12 to rise, providing a stable power source for the lifting and lowering of the movable plate 12.

[0037] When the air pump 4 stops working and the moving plate 12 descends, the torsion spring 63 releases its elastic potential energy, which drives the winding wheel 64 to rotate and rewind the rope 65, ensuring that the moving plate 12 can accurately return to its initial position and prepare for the next casting operation.

[0038] The working principle of the high-temperature alloy casting mold provided by this utility model is as follows:

[0039] Before the high-temperature alloy casting mold begins operation, the high-temperature alloy liquid is injected into the mold body 1. At this time, the heat-insulating riser assembly 2 covers the top of the mold body 1 to prevent heat loss and the entry of external impurities. The cooling fan 31 is started, and the spiral cooling pipe 32 begins to cool the high-temperature alloy liquid and accelerate its solidification. After the casting has solidified, the air pump 4 is started to fill the sealed chamber 5 with air. The pressure inside the sealed chamber 5 increases, pushing the moving plate 12 upward. During the upward movement of the moving plate 12, the pull rope 65 is gradually released, and the winding wheel 64... Driven by the pull rope 65, the coil rotates around the shaft 62. The torsion spring 63 twists and stores elastic potential energy until the pull rope 65 on the outer side of the winding wheel 64 is completely released. The moving plate 12 stops rising. At this time, the casting is pushed out to a suitable height to facilitate subsequent material removal operations. After the material removal is completed, the air pump 4 stops working, the pressure in the sealed chamber 5 decreases, the torsion spring 63 releases elastic potential energy, drives the winding wheel 64 to rotate in the opposite direction, rewinds the pull rope 65, and the moving plate 12 descends back to the initial position, waiting for the next casting operation.

[0040] Compared with related technologies, the high-temperature alloy casting mold provided by this utility model has the following beneficial effects:

[0041] Through the design of the limiting component 6, especially the cooperation between the winding wheel 64 and the pull rope 65, the rising height of the moving plate 12 can be precisely controlled. This effectively avoids the problem of the moving plate rising too high or too low, ensuring that the casting will not deviate or collide during the ejection process, greatly improving the dimensional accuracy and surface quality of the product, and reducing the product scrap rate. Furthermore, the precise limiting control allows the casting to be completely ejected in one go without the need for manual assistance, which greatly improves the material feeding efficiency and reduces production costs.

[0042] Second Embodiment

[0043] Please refer to the following: Figure 4 Based on the high-temperature alloy casting mold provided in the first embodiment of this application, the second embodiment of this application proposes another high-temperature alloy casting mold. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0044] Specifically, the second embodiment of this application provides a high-temperature alloy casting mold that differs in that a high-temperature alloy casting mold has a groove 7 on one side of the winding wheel 64, a threaded rod 71 rotatably connected to the inner side of the groove 7, and a limit plate 73 threadedly connected to the outer side of the threaded rod 71.

[0045] A handle 72 is fixedly installed at one end of the threaded rod 71.

[0046] One end of the limiting plate 73 is slidably connected to one side of the inner side of the slide groove 7.

[0047] The working principle of the high-temperature alloy casting mold provided by this utility model is as follows:

[0048] When adjusting the height of the movable plate 12 during use, the operator can first release the pull rope 65 required for the height of the movable plate 12 from the outer side of the take-up wheel 64. Then, rotate the handle 72 to drive the threaded rod 71 to make a threaded connection inside the limit plate 73, thereby moving the limit plate 73 downward and pressing the remaining pull rope 65 against the outer side of the take-up wheel 64. Then, the pull rope 65 required for the subsequent movement of the movable plate 12 is wound around the outer side of the take-up wheel 64. In this way, when the movable plate 12 moves, only the pull rope 65 on the outer side of the limit plate 73 will be released, thus limiting the lifting height of the movable plate 12.

[0049] Compared with related technologies, the high-temperature alloy casting mold provided by this utility model has the following beneficial effects:

[0050] The sliding groove 7, threaded rod 71, rotating handle 72 and limiting plate 73 work together to facilitate the user in adjusting the height of the moving plate 12 during use, so that the mold can adapt to different ejection requirements.
