Abstract
The utility model discloses an aluminum alloy oil pump cover low pressure casting double cast gate die, which comprises an upper die and a lower die matched with each other. The upper die is provided with a reinforcing rib cavity arranged corresponding to the position of the reinforcing rib of an aluminum alloy oil pump cover product. The upper die is also provided with a circular surface cavity arranged corresponding to the position of the circular surface of the aluminum alloy oil pump cover product. The circular surface cavity is provided with a first cast gate and a second cast gate. A shrinkage filling channel is arranged among the first cast gate, the second cast gate and the reinforcing rib cavity. The die provided by the utility model adopts double cast gates. Due to the arrangement of the double cast gates, the die filling process of aluminum water is ensured to be stable and orderly and the shrinkage filling of the aluminum water during the solidification process can be better performed. Therefore, the solidification of the aluminum water is orderly. The occurrence of the shrinkage cavity and the shrinkage porosity of products is effectively avoided.
