Abstract
Description
Technical Field

[0002] In the aerospace field, large, thin-walled, complex aluminum alloy shell castings (wall thickness 4mm ~ 30mm) are generally produced by sand mold low-pressure casting. Sand mold low-pressure casting can improve the density and mechanical properties of castings. With the increase in production demand, the complexity of castings is also getting higher and higher, and the dimensional accuracy and surface quality of castings need to be guaranteed. Taking the existing frame-type castings as an example, it is found in production that the top of the edge is often not poured in place when the casting is formed, and some gas will remain in the corners of the sand box, causing gaps or bubble defects during molding. The existing treatment methods include reserving air holes at the corners or pouring the corners separately. Since the height of the edges on the castings is not uniform and there are many of them, if air holes are reserved, it will cause excessive outflow of aluminum water. If the riser is poured separately, it will block the operating space, which is inconvenient to operate and has great production difficulties. Utility Model Content

[0016] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.
[0017] See also Figures 1 to 3The embodiment of the utility model discloses a multi-angle adjustment device for pouring, which mainly includes a first slot runner 1 connected to a sand box. The bottom of the first slot runner 1 can also be connected to an auxiliary frame to improve the convenience of pouring. The upper part of the first slot runner 1 is provided with an auxiliary slot runner 2 through a connecting structure. This design allows the runner structure to be expanded as needed to adapt to different pouring requirements.
[0018] The first slot runner 1 and the auxiliary slot runner 2 are both provided with a variety of different height specifications, so that the device can select a suitable height specification according to actual casting requirements, so as to make the overall height consistent and make the risers at the same height, thereby realizing precise control of the casting process. The discharge ports 101 on the first slot runner 1 and the auxiliary slot runner 2 are respectively provided, and a suitable height can be selected according to the different heights of the edge edges to ensure the use effect.
[0019] During the pouring process, molten aluminum flows into the sand box through the first slot runner 1 and the auxiliary slot runner 2. In order to ensure the smooth flow of molten aluminum, discharge ports 101 are provided on the sides of the first slot runner 1 and the auxiliary slot runner 2. The bottom surface of the discharge port 101 is designed to be a downward inclined surface, which helps the molten aluminum to smoothly enter the sand box. The discharge port 101 on the first slot runner 1 is used to pour the bottom and sides of the edge, and the discharge port 101 of the upper auxiliary slot runner 2 is used to assist in pouring the top of the edge. When in use, under the influence of gravity, the inside of the sand box will be filled from the bottom upwards. Since the height of the riser remains horizontal, when air remains at the top of the edge, it can be discharged through the discharge port 101 of the auxiliary slot runner 2. During the pouring process, the auxiliary slot runner 2 is used to directly pour the top of the edge to reduce air retention and greatly ensure the pouring effect.
[0020] The connection structure includes a receiving groove 102 arranged on the top of the first slot runner 1, and a connecting portion that is clamped with the receiving groove 102 is arranged at the bottom of the auxiliary slot runner 2. The first slot runner 1 and the auxiliary slot runner 2 can be designed to be cylindrical, and the discharge port 101 can be vertically arranged. The auxiliary slot runner 2 can be conveniently connected to the first slot runner 1 through the receiving groove 102 to form an integral runner structure, which not only simplifies the manufacturing process but also ensures the stability of the casting process.
[0021] The receiving groove 102 is arranged downward along the inner wall of the first runner, and its depth is 3-6 cm. A plurality of guide grooves 103 are arranged at the bottom of the receiving groove 102 along the inner wall of the first runner, and an annular clamping groove 104 is arranged at the bottom of the guide groove 103. This design enables the connecting part to slide smoothly along the guide groove 103 when inserted into the receiving groove 102 until the clamping groove 104 is connected to the clamping joint 203, thereby realizing a stable connection between the auxiliary gap runner 2 and the first gap runner 1.
[0022] The connection part includes a convex ring 201 that is clamped with the receiving groove 102. The side of the convex ring 201 is provided with an expansion joint, so that the convex ring 201 has a certain elasticity when inserted into the receiving groove 102, and can be quickly connected and disassembled with the receiving groove 102 to ensure the tightness of the connection. The lower part of the convex ring 201 is provided with a connecting column 202 that is clamped with the guide groove 103. The bottom of the connecting column 202 is provided with a clamping joint 203 connected with the clamping groove 104. The clamping joint 203 is spherical. This design enables the connection part to automatically connect with the clamping groove 104 after being inserted into the receiving groove 102, without additional fixing measures, thereby simplifying the installation process. After the connection, the overall inner wall is smooth, which is convenient for the flow of aluminum water and improves the casting effect. When demoulding, the internal residue can be melted and flowed out by heating using the low melting point of aluminum, and can be reused.
[0023] In order to further improve the flexibility of the device, a transition joint 3 can be further provided between the first gap runner 1 and the auxiliary gap runner 2. The transition joint 3 is connected to the gap runner and the auxiliary runner through a connecting structure, and the transition joint 3 is provided with a variety of height sizes, which can adapt to a wider range of casting scenarios and adjust the heights of the first gap runner 1 and the auxiliary gap runner 2 so that the risers are on the same horizontal plane to meet different casting requirements.
[0024] In general, the unique connection structure and a variety of optional structural features can achieve precise control of the pouring process. It is not only simple in structure and easy to operate, but also has high applicability and flexibility. It can be widely used in the design and adjustment of runner structures in the sand box pouring process. Through multi-angle adjustment, the pouring process can be adjusted to reduce defects at the edges during the pouring process, thereby effectively improving the pouring efficiency and quality.
