Aluminum bar casting plate with explosion-proof sheet

The utility model relates to the technical field of casting, and particularly discloses an aluminum bar casting plate with an explosion-proof sheet, which comprises a casting plate body, a crystallizer, a molten aluminum runner, a casting plate supporting and positioning hole and a water inlet hole, the interior of the pouring disc body is of a hollow structure, a cooling water sealing cavity is formed in the pouring disc body, the cooling water sealing cavity is internally communicated with a water inlet, cooling water is fed into the cooling water sealing cavity, and the other side of the cooling water sealing cavity is communicated with a water outlet, so that internal water circularly flows, the temperature of molten aluminum is reduced, and pouring preparation of aluminum bars is achieved. A plurality of explosion-proof holes are communicated in the cooling water sealing cavity, and explosion-proof pieces cover the explosion-proof holes and are fixed through sealing rubber stripsand pressing rings.
