The invention relates to molten pool type heat preservation casting equipment. The molten pool type heat preservation casting equipment comprises a heat preservation furnace, one or more shunting packages and a platform stand column, wherein the heat preservation furnace comprises a furnace body, a furnace cover covering the opening of the furnace body, a heat preservation cover covering the furnace cover, and one or more lift tubes inserted in the furnace body; the heat preservation cover is additionally mounted on the furnace cover of the heat preservation furnace, and a furnace gas inlet which directly faces a furnace gas communicating hole in the furnace cover is formed in the bottom of the heat preservation cover, so that the internal part of the heat preservation cover is filled with hot furnace gas in a molten pool; then the lift tube is inserted into the molten pool through the heat preservation cover, and the heating and the heat preservation of a throat opening can be realized through furnace gas. Through the adoption of the technical scheme, a separate heating device does not need to be arranged; the heat preservation cover is arranged, so that recycling residual heat is realized, the purposes of saving energy and reducing consumption are achieved, besides, the temperature of the furnace gas is basically the same as that of molten metal, when the throat opening is heated, the temperature of the throat opening is the same as that of the molten pool, the temperature and the state of the molten metal in the throat opening are the same as the temperature and the state of the molten metal in the molten pool, and the heating effect is optimal.
