Description

Technical Field

[0001] The utility model relates to the technical field of sand mold casting, in particular to sand mold casting forming equipment. Background Art

[0002] Sand casting is a widely used casting method. As the name suggests, it involves creating a mold using sand. Sand casting involves placing a finished part model or wooden pattern (pattern) in the sand. The pattern is then filled with sand. Once the pattern is removed from the box, the sand forms the mold.

[0003] Current sand mold casting devices are prone to clogging at the sand discharge point during use. Therefore, some people have thought of setting a scraper in the sand hopper to assist in sand discharge. For example, Chinese utility model patent No. CN221494137U specifically discloses a sand mold forming device for casting automotive parts.

[0004] However, during the actual use of the above-mentioned sand mold casting forming device, people will find that when the device discharges sand, it shakes the leakage plate and then cooperates with the scraper to assist in discharging. However, since the leakage plate is plugged into the sand hopper, when it is shaken, it is easy to cause the casting sand to leak from the side of the sand hopper, affecting its normal use. Utility Model Content

By adding foundry sand to the sand hopper and then starting the first drive motor to drive the first and second rotating rods to rotate, the first and second scrapers on the first rotating rod are used to turn the foundry sand to prevent it from piling up on the screen plate and causing blockage. The sieved foundry sand then enters the discharge port and is discharged as the auger rotates.
