Along with automobile industry's development, more and more auto-parts adopt the die casting, and simultaneously, the shape of automobile die casting product is also more and more complicated, and its inside quality requirement is also more and more high, for example often have the boss of protrusion in product major structure on the die casting, be equipped with the screw hole of installation usefulness on the boss, the shape of boss and the orientation of screw hole do not do benefit to the shaping of product and guarantee good foundry goods internal quality in addition. The method is generally adopted to arrange a slag ladle at the boss structure of a product, and the internal quality of the boss structure of a casting is improved through the slag collection effect of the slag ladle. However, the following problems exist in the using process:
1. the overflow port of the slag ladle is thinner, so that the slag ladle is easily clamped on the static die and cannot smoothly separate from the casting when the die is opened. Causing the slag ladle structure to have a failure state in the subsequent production, and finally causing the internal quality of the product at the protruding structure to be unstable.
2. Because the boss structure is positioned at the tail end of the casting and is also the tail end of the die-casting filling, the situation of poor filling is easy to occur, firstly, the temperature of the alloy liquid is lower when reaching the tail end, and secondly, the casting pressure is not easy to transfer.
3. The die casting alloy liquid shrinks in volume during solidification. When the pressure is insufficient at the thick and solid area of the casting, shrinkage cavities appear in the corresponding area, and the protruding structure of the product is the thick and solid area.
At present, the problem that the slag ladle is adhered to the fixed die is solved by realizing demoulding through the draw hook on the movable die, but the slag ladle still can be adhered to the movable die and the problems of the points 2 and 3 cannot be completely solved.
