Abstract
Description
Technical Field
[0001] This utility model relates to the field of resin sand casting technology, specifically a new type of sand box for horizontal casting to vertical pouring. Background Technology
[0002] In the foundry industry, traditional resin sand casting and sand box casting hold a crucial position. Traditional resin sand casting, with its excellent collapsibility and high strength, is widely used in casting production, effectively ensuring the dimensional accuracy and surface quality of castings. Sand box casting provides a stable container for molding sand, facilitating molding and box assembly, making it an indispensable part of the casting process. However, currently, both processes are mostly based on horizontal molding. When pouring is performed after the sand box is assembled, this method reveals significant drawbacks. Because the molten metal impacts the molding sand horizontally, for some planar structures, the strong impact force can easily cause the molding sand to move and peel off. This leads to sand erosion during casting, resulting in a rough and uneven surface; it can also cause sand inclusions, forming sand particles inside the casting, severely affecting the mechanical properties and service life of the casting. These problems not only increase the scrap rate and production costs but also limit the application of casting processes in the production of high-quality castings.
[0003] To address the aforementioned issues, a novel sand box for horizontal casting to vertical pouring is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a novel sand box for horizontal casting to vertical pouring, in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel sand box for horizontal casting to vertical pouring, comprising a pouring base, a pouring sand box body being engaged with the outer side of the top of the pouring base, a decorative boss being fixedly provided in the middle of the top of the pouring base, two pouring pipes being provided on one side of the decorative boss, a diversion pipe being fixedly connected between the two pouring pipes on the side away from the decorative boss, a feed pipe being fixedly connected in the middle of the diversion pipe on the side away from the pouring pipe, a decorative ring being fixedly provided in the middle of the top of the decorative boss, a plurality of decorative strips being fixedly provided on the inner side of the decorative ring, decorative protrusions being fixedly provided between the plurality of decorative strips, and the decorative protrusions being fixedly connected to the decorative boss.
[0006] This sand box structure can satisfy both horizontal shaping and vertical pouring by flipping the sand box. By setting two pouring pipes on one side of the decorative boss, molten metal can be injected simultaneously through these two pipes, resulting in a more uniform distribution of the molten metal within the pouring cavity. This reduces defects such as porosity and shrinkage caused by uneven liquid flow, improving the internal quality of the casting. A distribution pipe is fixedly connected between the two pouring pipes on the side away from the decorative boss. The distribution pipe plays a role in evenly distributing the molten metal from the feed pipe to the two pouring pipes according to a certain ratio and flow rate, ensuring consistent flow rates in both pouring pipes. This further guarantees uniform filling of the pouring cavity with molten metal and avoids defects such as sand inclusions and sand erosion that may occur in some planar structures. Preferably, a casting cavity is provided in the middle of the main body of the casting sand box, and the casting cavity is correspondingly provided with the decorative protrusion.
[0007] Preferably, reinforcing columns are fixedly installed on all four sides of the main body of the casting sand box.
[0008] Preferably, a number of evenly distributed reinforcing strips are fixedly provided on the surface of the main body of the sand casting box.
[0009] Preferably, a second fixing member is fixedly provided on both sides of the casting base, and a second fixing hole is opened in the middle of the two second fixing members. A first fixing member is fixedly provided at the bottom of both sides of the casting sand box body, and a first fixing hole is opened in the middle of the two first fixing members.
[0010] Preferably, the two first fasteners are respectively provided with two second fasteners.
[0011] Preferably, the diameter between the two first fixing holes and the diameter of the two second fixing members are both 4 mm.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the sand box structure can satisfy both horizontal shaping and vertical pouring by flipping the sand box. By setting two pouring pipes on one side of the decorative boss, the molten metal can be injected simultaneously through these two pouring pipes, which can make the molten metal distributed more evenly in the pouring cavity, reduce defects such as porosity and shrinkage caused by uneven liquid flow, and improve the internal quality of the casting. A diversion pipe is fixedly connected between the two pouring pipes on the side away from the decorative boss. The diversion pipe plays the role of evenly distributing the molten metal. It can distribute the molten metal from the feed pipe to the two pouring pipes according to a certain proportion and flow rate, ensuring that the flow rate of the two pouring pipes is consistent, further ensuring the uniform filling of the molten metal in the pouring cavity, and avoiding defects such as sand flushing and sand inclusion in some planar structure products.
