Technical Field

[0001] The utility model relates to the technical field of sand casting, in particular to a sand casting device for castings. Background Art

[0002] Sand casting refers to the production of castings using clay-bonded sand as modeling materials. It is a process with a long history and is also the most widely used process. Speaking of its long history, it can be traced back to thousands of years ago; as for its scope of application, it can be said that it is used everywhere in the world. Sand casting is a production method in which molten metal is poured into the cavity of the mold and the product is obtained after cooling and solidification.

The casting mold of the utility model adopts a split type, which is convenient for the removal of sand after the casting is completed. The casting mold is driven by a first hydraulic cylinder, does not require manual labor, has good sealing, and is easy to operate. The isolation plate can play a fixing role to ensure that the sand in the casting mold is symmetrically divided into two parts. The moving plate is driven by the second hydraulic cylinder to further compress the sand inside the two groups of mold grooves, thereby improving the quality of casting production;
