Abstract
Description
Technical Field
[0001] The utility model belongs to the field of flywheel housing sand core dip coating, in particular to a flywheel housing sand core dip coating bracket. Background Art
[0002] The flywheel housing sand core is a circular structure with a closed bottom and an open top.
[0003] The dip coating process refers to coating the outer surface of the flywheel housing sand core with paint and then drying it to facilitate the separation of the sand core and the flywheel casting after casting.
[0004] The cavity of the flywheel housing sand core, that is, the inner surface of the flywheel housing sand core cannot be coated with paint and needs to maintain a certain degree of dryness, otherwise it is easy to cause cracking during the casting process. The flywheel housing sand core dip coating needs to ensure that the outer surface coating is uniform and the liquidus line position is fixed.
[0005] The robot dip-coats the flywheel housing sand core. The bracket serves as the bearing mechanism of the sand core. It is necessary to ensure that the position of the flywheel housing sand core on the bracket is fixed and cannot be moved.
[0006] The bottom of the flywheel housing sand core is flat and has a large area. Due to the high specific gravity of the coating, the buoyancy is also large. During the dipping process, the sand core's own weight cannot ensure that its position on the bracket is fixed, and the flywheel housing sand core is easy to leave the bracket and float up.
