The invention relates to a general automatic slag ladle removing device and a slag removing system for die casting production. The general automatic slag ladle removing device comprises a bottom plate, an upright column and a table, wherein the upright column is arranged on the bottom plate; the table is connected with the upright column; a moving block is arranged on the table and can move in the direction of the table; threaded holes are formed in the upper plane and side surfaces of the moving block; a collision bolt is connected to the inside of the threaded hole of the upper plane of the moving block in a screwed manner; adjusting bolts are connected to insides of threaded holes of the side surfaces of the moving block in a screwed manner; and the collision bolt can be adjusted in the vertical direction through self threads and can be adjusted in the horizontal direction through the adjusting bolts. The general automatic slag ladle removing device has the beneficial effects that by the automatic slag ladle removing device, the table, the moving block and the collision bolt are combined, the position of the collision bolt can be adjusted freely to adapt to distribution of slag ladles on different products, the removed slag ladles are directly recycled into a recycling trolley by a baffle, a die casting field environment is protected, resources are saved, and the automatic slag ladle removing device is environmentally friendly.
