A core baking method for a water-cooled motor shell of a
new energy vehicle includes the steps of
coating: immersing a sand core in a paint, evenly
coating a layer of paint on the surface of the sandcore, placing the sand core on a sand core frame, naturally
drying the paint, and brushing the uncoated part by a
brush; self-inspection: ensuring that the
surface coating of a jacket core shall be uniform, free of flow marks, and judging whether the rough part of the inner ring of the
water jacket is evenly coated; core baking: first checking whether the oven and instrument are in good condition,setting the core baking temperature at 77 DEG C and the core baking time for 2.4 to 3 hours, that sand core of the
coating rack is put on a
drying rack aft the
surface coating is dried, and then putting the coated sand core on a baking rack after the paint on the sand core becomes dry, hoisting the sand core on a trolley of the oven via hoist, driving the trolley into the oven, closing the door,switching on the power, switching off the power after
heating time is over, pulling out the trolley from the oven for cooling. The
electric heating oven is used for
drying, the drying effect is good,and the drying environment is good.
