Description

Technical Field

[0001] This utility model relates to the field of shaped chills technology, specifically a shaped chill for casting aluminum alloy housings of high-voltage switches. Background Technology

[0002] During casting production, in order to ensure sequential solidification of castings, good microstructure in large and complex parts of the castings, and reduce defects such as shrinkage porosity and shrinkage cavities caused by heat formation, it is often necessary to place conformal chills in multiple specific locations in the mold in advance to improve casting quality and avoid the risk of product scrap. Forming chills are also used in the casting of aluminum alloy housings for high-voltage switches.

[0003] In response, Chinese Patent Application Publication No. CN207695600U discloses a castable chill, specifically relating to the field of casting technology. The chill includes a chill body with a sand-coated template inside. A molding sand filling layer is located at the bottom of the sand-coated template, and a casting is positioned at the bottom of the molding sand filling layer. This invention improves the surface quality of the casting while preventing internal porosity and shrinkage cavities. It also increases the molding sand strength of the chill and enhances its heat absorption area, allowing for repeated use.

[0004] However, in actual use, most existing chills are solid and do not have internal cooling channels, which slows down the heat absorption rate and the overall cooling speed. At the same time, chills also require a certain degree of stability when installed on the outer surface of the aluminum alloy housing of high-voltage switches. Therefore, improving and perfecting the above-mentioned problems has become an urgent issue to be addressed. Utility Model Content

[0005] The purpose of this utility model is to provide a molded chill for casting aluminum alloy housings of high-voltage switches, in order to solve the problems mentioned in the background art. Most of the existing chills are solid in use and do not have cooling grooves inside, which leads to a slower heat absorption rate and a slower overall cooling speed. At the same time, the chills also need a certain degree of stability when installed on the outer surface of the aluminum alloy housing of high-voltage switches.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a forming chill for casting aluminum alloy housing of a high-voltage switch, comprising a first forming chill, a second forming chill mounted on the right side of the first forming chill, a heat dissipation cavity opened inside the first forming chill, a first heat-conducting block mounted on the inner side wall of the first forming chill, a heat-conducting connecting frame mounted on the lower surface of the first heat-conducting block, and a second heat-conducting block mounted on the lower end of the heat-conducting connecting frame;

[0007] A heat-conducting arc frame is installed on the left side surface of the first forming chill. An arc groove is provided on the left side of the heat-conducting arc frame, and through slots and through holes are sequentially opened inside the heat-conducting arc frame from front to back.

[0008] Preferably, a mounting block is installed on the back of the heat dissipation cavity, and a mounting post is installed on the top surface of the mounting block.

[0009] Preferably, a top frame is mounted on the upper surface of the mounting block, and an mounting groove is provided inside the top frame, which is compatible with the mounting column.

[0010] Preferably, connecting shafts are inserted and installed on both the left and right sides of the top frame, and connecting plates are installed on the outer surface of the connecting shafts.

[0011] Preferably, a fixing post is installed on the outer surface of the connecting plate, and a mounting base is installed on the outer surface of the fixing post.

[0012] Preferably, the surface of the mounting base is fitted with mounting bolts, and two sets of mounting bolts are provided.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This high-voltage switch aluminum alloy housing casting forming chill, through the setting of a first forming chill, a heat dissipation cavity, a first heat-conducting block, a heat-conducting connecting frame, a second heat-conducting block, a second forming chill, a heat-conducting arc frame, an arc groove, a through hole, and a through slot, is used by first fitting the first and second forming chills together on the outer surface of the high-voltage switch aluminum alloy housing. The first and second forming chills can then dissipate heat and cool the outer surface of the housing. Furthermore, the design of the heat dissipation cavity accelerates the heat dissipation and cooling of the first forming chill. The first heat-conducting block, heat-conducting connecting frame, and second heat-conducting block inside the first-formed chill can also absorb heat from the hotter gas inside the heat dissipation cavity and dissipate it with the heat dissipation cavity. At the same time, a heat-conducting arc frame is also installed on the left side of the first-formed chill, which can also conduct heat for cooling. The arc groove design makes the contact area between the heat-conducting arc frame and the outside air wider, resulting in a better overall cooling effect between the heat-conducting arc frame and the first-formed chill after heat absorption. Furthermore, the design of multiple through holes and through grooves makes the air circulation faster, demonstrating the practicality of the design.

[0015] 2. This high-voltage switch aluminum alloy housing casting forming chill, through the setting of mounting blocks, mounting columns, top frames, mounting grooves, connecting shafts, connecting plates, fixing columns, mounting seats, and mounting bolts, in use, when the first forming chill and the heat dissipation cavity are installed as a whole on the outer surface of the housing, the top frame is installed on the top surface of the mounting block, and then the mounting column is installed inside the mounting groove. Subsequently, it is fixedly connected to the connecting plate through the connecting shaft, and the connecting shaft can rotate inside the top frame. The mounting seat is installed as a whole on a platform or the ground, and the mounting seat is fixed to the platform or the ground through the mounting bolts. This ensures that it can stably abut against the back of the mounting block and the second forming chill, thereby ensuring the stability of the first and second forming chills during operation and reflecting the functionality of the design.

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.

[0022] Please see Figures 1-4 One embodiment provided by this utility model:

[0023] A molding chill for casting aluminum alloy housings of high-voltage switches is disclosed in this application. The first molding chill 1, heat dissipation cavity 2, first heat-conducting block 3, heat-conducting connecting frame 4, and heat-conducting arc frame 7 used in this application are all commercially available products. Their principles and connection methods are well-known prior art and will not be elaborated further here. The chill includes a first molding chill 1, a second molding chill 6 mounted on the right side of the first molding chill 1, a heat dissipation cavity 2 inside the first molding chill 1, a first heat-conducting block 3 mounted on the inner wall of the first molding chill 1, a heat-conducting connecting frame 4 mounted on the lower surface of the first heat-conducting block 3, a second heat-conducting block 5 mounted at the lower end of the heat-conducting connecting frame 4, a mounting block 11 mounted on the back of the heat dissipation cavity 2, a mounting post 12 mounted on the top surface of the mounting block 11, a top frame 13 mounted on the upper surface of the mounting block 11, and a mounting groove 14 inside the top frame 13. The mounting groove 14 and the mounting post 12 are mutually compatible. The top frame 13 has mounting grooves on both the left and right sides. A connecting shaft 15 is inserted and installed. A connecting plate 16 is installed on the outer surface of the connecting shaft 15. A fixing post 17 is installed on the outer surface of the connecting plate 16. A mounting seat 18 is installed on the outer surface of the fixing post 17. Mounting bolts 19 are installed on the surface of the mounting seat 18. There are two sets of mounting bolts 19. When the first forming chill 1 and the heat dissipation cavity 2 are installed on the outer surface of the housing, the top frame 13 is installed on the top surface of the mounting block 11. Then the mounting post 12 is installed inside the mounting groove 14. Subsequently, it is fixedly connected to the connecting plate 16 through the connecting shaft 15. The connecting shaft 15 can rotate inside the top frame 13. The mounting seat 18 is installed on the platform or the ground. The mounting seat 18 is fixed to the platform or the ground through the mounting bolts 19. This ensures that it can stably abut against the back of the mounting block 11 and the second forming chill 6, thereby ensuring the stability of the first forming chill 1 and the second forming chill 6 during operation.

[0024] A heat-conducting arc-shaped frame 7 is installed on the left side surface of the first formed chill 1. An arc-shaped groove 8 is provided on the left side of the heat-conducting arc-shaped frame 7. A through groove 10 and a through hole 9 are sequentially formed from front to back inside the heat-conducting arc-shaped frame 7. First, the first formed chill 1 and the second formed chill 6 are integrally fitted onto the outer surface of the high-voltage switch aluminum alloy housing. Thus, the first formed chill 1 and the second formed chill 6 can dissipate heat and cool the outer surface of the housing. Furthermore, the design of the heat dissipation cavity 2 can accelerate the heat dissipation and cooling of the first formed chill 1. Simultaneously, the first formed chill... The first heat-conducting block 3, the heat-conducting connecting frame 4, and the second heat-conducting block 5 inside the iron 1 can also absorb heat from the hotter gas inside the heat dissipation cavity 2 and dissipate it with the heat dissipation cavity 2. At the same time, a heat-conducting arc frame 7 is also installed on the left side of the first formed chill 1. The heat-conducting arc frame 7 can also conduct heat and cool. The design of the arc groove 8 makes the contact area between the heat-conducting arc frame 7 and the outside air wider, so that the overall cooling effect between the heat-conducting arc frame 7 and the first formed chill 1 is better after heat absorption. Furthermore, the design of multiple sets of through holes 9 and through grooves 10 makes the air circulation faster.

[0025] Working Principle: In use, the first formed chill 1 and the second formed chill 6 are first integrally attached to the outer surface of the aluminum alloy housing of the high-voltage switch. The first and second formed chills 1 and 6 dissipate heat and cool the outer surface of the housing. The design of the heat dissipation cavity 2 accelerates the heat dissipation and cooling of the first formed chill 1. Simultaneously, the first heat-conducting block 3, the heat-conducting connecting frame 4, and the second heat-conducting block 5 inside the first formed chill 1 absorb heat from the hotter gas inside the heat dissipation cavity 2, which then dissipates with the heat dissipation cavity 2. A heat-conducting arc frame 7 is also installed on the left side of the first formed chill 1, which also conducts heat for cooling. The arc groove 8 design allows the heat-conducting arc frame 7 to interact with the outside air. With a wider contact area, when the first forming chill 1 and the heat dissipation cavity 2 are installed on the outer surface of the housing, the top frame 13 is installed on the top surface of the mounting block 11, and the mounting column 12 is installed inside the mounting groove 14. Then, it is fixedly connected to the connecting plate 16 through the connecting shaft 15, and the connecting shaft 15 can rotate inside the top frame 13. The mounting base 18 is installed on the platform or ground, and the mounting base 18 is fixed to the platform or ground through the mounting bolts 19. This ensures that it can stably abut against the back of the mounting block 11 and the second forming chill 6, thereby ensuring the stability of the first forming chill 1 and the second forming chill 6 during operation. The above is the working principle of this utility model.
