Description
Technical Field
[0001] This utility model belongs to the field of sand casting technology, specifically relating to a sand casting sand spreading device for sand casting. Background Technology
[0002] Sand casting is a traditional casting process and one of the most widely used casting methods. It uses sand as the molding material to create a mold, pours molten metal into the mold, and after cooling and solidification, obtains a metal casting of the desired shape and size. Sand casting is highly flexible, capable of producing castings of various sizes, shapes, and materials, suitable for single-piece, small-batch, and mass production. It has important applications in many fields such as machinery manufacturing, automobiles, aerospace, shipbuilding, and energy. Foundry sand is a key molding material used to prepare molding sand and core sand in casting production. Its performance directly affects the quality of castings, production efficiency, and cost. In the sand casting process, the foundry sand needs to be spread evenly to ensure dimensional accuracy, enhance product stability, permeability, and good surface quality, while also promoting smooth pouring and improving casting quality. However, existing spreading devices often result in uneven spreading due to the wide width of the spread at one time, leading to less foundry sand on the sides compared to the center, affecting subsequent use. Furthermore, they cannot be adjusted according to the foundry sand and the required spreading thickness, thus impacting user experience.
[0003] In view of the above factors, this utility model provides a casting sand spreading device for sand casting to achieve uniform spreading and convenient adjustment. By setting three feed pipes on the box cover, the casting sand can be evenly fed into the storage box. At the same time, the scraping component can scrape the casting sand flat, thereby further uniformizing the casting sand and improving the uniformity of the casting sand in the storage box, thereby improving the uniformity of the sand output. Furthermore, by adjusting the position of the adjusting plate, the size of the discharge port can be adjusted, thereby adjusting the sand output rate. Utility Model Content

The storage box 5 is located above the installation platform 1 and the receiving plate 3 with a distance between them. The lower end of the storage box 5 is provided with a discharge port 6. Adjusting plates 7 are slidably engaged on both sides of the discharge port 6. By adjusting the position of the adjusting plates 7, the size of the discharge port 6 can be adjusted, thereby adjusting the sand discharge rate.
[0026] To facilitate the rotation of the translation threaded rod within the translation slide rail during use, the translation assembly 4 includes a translation slide rail 401. The translation slide rail 401 is fixedly installed on both sides of the outer side of the mounting platform 1, and a control motor 402 is fixedly installed at one outer end of the translation slide rail 401. A translation threaded rod 403 is fixedly installed at the output end of the control motor 402, and both ends of the translation threaded rod 403 are rotatably engaged with the inner ends of the translation slide rail 401.
[0027] In order to facilitate the movement of the support rod during use, thereby moving the storage box and completing the spreading of casting sand, the support rod 404 is slidably engaged inside the translation slide rail 401. The lower part of the support rod 404 is rotatably engaged on the translation threaded rod 403, and the storage box 5 is fixedly installed between the support rods 404.
[0028] In order to facilitate the movement of the adjusting plate in the sliding groove during use, thereby adjusting the size of the discharge port, sliding grooves 11 are provided on both sides of the discharge port 6.
