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.
