The invention discloses an automatic precision core
assembly moulding
production line, a
casting production line and a production method thereof, wherein the core
assembly moulding
production line comprises an outer die core making area, an outer die core delivery line, an outer die core surface-
drying furnace, a mould cavity core making area, a mould cavity delivery line, a mould cavity surface-
drying furnace and a core
assembly delivery line; a
robot I with transportation and assembly functions is disposed on the core assembly moulding production line; the
casting production line further comprises a pouring line and a
robot II with a transportation function; all the sand cores used by the core assembly are produced, delivered and assembled on the core assembly moulding production line; moreover, all the actions are realized by a highly-automatic method, and robots are used for core assembly, so that the
automation degree is high, the labour intensity of workers is low, the
working environment is good, the production efficiency is high, the energy is saved, the consumption is decreased, the process stability is good, and the product precision is high; the sand cores used by the core assembly are shot by a cold-box core making
machine; and the cast product has a
high dimensional precision, a good appearance quality and a high production efficiency.
