Description

Technical Field

[0001] The utility model relates to the technical field of cleaning cast iron weight moulds, in particular to a sand mould for processing cast iron weights which is easy to clean. Background Art

[0002] A forging die is a die used to forge cast iron parts. A cast iron forging die is one of many types of dies. However, traditional cast iron forging dies are not easy to clean, which results in the entire device not being able to be used well and not being able to cool and dissipate heat well. During the forging process, the entire die needs to be lowered for extrusion forging, which can easily cause a great impact on the die and affect the service life of the entire device. Therefore, a cast iron forging die that is easy to clean is needed to solve the above problems.

[0003] For example, Chinese patent announcement No. CN218743572U discloses a cast iron forging die that is easy to clean. When in use, the water inlet is connected to an external water source, and then the water pump is driven so that the water pump presses the water in the water pipe into the water tank through the water inlet. Then the cast iron forging die that needs to be cleaned is placed in a placement frame, and then the motor is started. The motor drives the belt pulley to rotate, and the belt pulley drives the threaded rod to rotate forward to make the placement frame sink into the water tank. The belt pulley drives the threaded rod to rotate reversely to make the placement frame come up, so that the placement frame can be moved up and down in the water tank. Adjustment, the placement frame is covered with through holes all around, when the cast iron forging mold is cleaned in the water tank, the water in the water tank can come in from the through holes around the placement frame, so that the cast iron forging mold can be cleaned up and down inside the water tank, and the motor drives the pulley to rotate, and the rotation of the pulley can drive the push rod to move, so that the placement frame is swung back and forth for cleaning. After the cleaning is completed, the pulley drives the threaded rod to reverse to make the placement frame come up, which is convenient for taking, and then the water inside the water tank is discharged through the drain outlet to discharge the sewage. The device is simple to operate and improves applicability.

[0004] However, the easy-to-clean cast iron forging die in the above application is only cleaned by immersing the die in water, and the stubborn stains adhered to the inside of the die are not well cleaned. Therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide a sand mold for processing cast iron weights that is easy to clean. Utility Model Content
