[0002] Most of the cores are surrounded by high-temperature liquid metal in the mold. Inevitably, a large amount of waste cores will be generated during the production of cast pipes. How to clean up the generated waste cores is a problem that must be solved.

[0003] In the existing waste core collection devices, such as a waste core automatic collection device with the application number CN201821062552.5, its technical solution is as follows: It includes a collection device and a receiving device. The collection device includes a waste core aggregate hopper, a first support, a rotatable connecting arm, and a lifting hydraulic device. The receiving device includes a waste core receiving platform, a second support, a weighing pressure sensor, a bucket, a third support, and a reciprocating hydraulic device. When in use, the waste cores fall onto the waste core receiving platform, and the reciprocating hydraulic device pushes the bucket to shovel the waste cores on the waste core receiving platform into the waste core aggregate hopper. When dumping the waste cores, the lifting hydraulic device on the right side of the bottom of the waste core aggregate hopper jacks up the right side of the waste core aggregate hopper, driving the waste core aggregate hopper to tilt at a certain angle, and completing the dumping operation under the action of the rotatable connecting arm. However, in the existing ductile iron casting process, when leveling the sand cores in the mold box, the waste cores cannot be centrally collected, resulting in the difficulty of cleaning up the excess sand cores scattered around the ductile iron casting mold box.

[0004] In view of this, in-depth research on the above problems has led to the generation of this case.

[0005] In response to the above problems, an innovative design is carried out on the basis of the original waste core collection device. Content of the Utility Model
