Description

Technical Field

[0001] The utility model relates to the technical field of sand mold tamping, in particular to a sand mold tamping tool. Background Art

[0002] Sand casting refers to a casting method that produces castings in sand molds. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting. The basic raw materials for making sand molds are foundry sand and sand binder. The most commonly used foundry sand is siliceous sand. The loose sand particles need to be compacted during sand casting.

[0003] In existing production, due to the lack of suitable tamping tools, excessive force is often used to damage the aluminum mold or the sand mold is not solid due to fear of using force, especially some key edge seams. If they are not tamped solid, the product quality will be seriously affected. Application No. 202221689892.7 discloses a sand mold tamping tool, including a holding tube body, a telescopic inner tube is mounted inside the holding tube body, and an inner tube fixing device is arranged between the holding tube body and the telescopic inner tube; the top of the telescopic inner tube is located outside the top of the holding tube body, and a small-headed tamping piece suitable for sand mold corners and special positions is installed outside the top of the holding tube body, and a large-headed tamping piece suitable for large-area tamping is installed at the bottom of the holding tube body, and the tamping area of ​​the small-headed tamping piece is smaller than that of the large-headed tamping piece. The above-mentioned tamping tool can be adjusted in length to meet the needs of different sizes. The shape of the product requires it, but the adjustment between the telescopic inner tube and the holding tube body can only be adjusted by rotating the fixing screws, and different types of casting molds require tools of different lengths for compaction. Therefore, the adjustment between the telescopic inner tube and the holding tube body is more frequent, and the fixing screws are used to adjust the limit, wherein the screw rotation takes a long time, and during the adjustment, the screws are easily lost or even dropped into the mold, which not only causes the adjustment efficiency between the telescopic inner tube and the holding tube body to be low, but also easily causes the phenomenon of poor casting quality.
