Description

technical field [0001] The invention relates to the field of a sand core hanger, in particular to a sand core hanger which uses the self-weight of the sand core to automatically turn over. Background technique [0002] At present, sand cores are materials used to manufacture mold cores in foundry production. They are composed of foundry sand and sand binders. The operation may require the cooperation of multiple people. If the cooperation is not good, the sand core may be damaged. There may be certain safety hazards, which will bring losses and waste to production and reduce work efficiency. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides a sand core lifter that uses the self-weight of the sand core to turn over automatically. Bring loss and waste, reduce the problem of work efficiency. [0004] The present invention is achieved like this: [0005] The utility model relates to a sand core hanger which use...
