AI Technical Summary
Technical Problem
Impurities can easily enter the mold cavity during the casting process of molten metal, affecting the quality of the casting.
Method used
The cavity of the pouring cup is divided into a first chamber and a second chamber by a separator. The flow of the molten metal is controlled by the first and second separators to ensure that impurities are deposited in the second chamber and melted at a preset height, thereby achieving the separation of impurities from the clean molten metal.
Benefits of technology
It effectively reduces the probability of impurities entering the gating system, improves casting quality, ensures pouring continuity and work efficiency, and prevents impurities and air from mixing in.

Abstract
A casting sprue cup comprises a cup body, a partition and a first partitioning member, the cup body is provided with a pouring hole and a cavity for containing a metal solution; the partition is connected to the cup body and separates the cavity into a first chamber and a second chamber, the partition is provided with a passage communicating the first chamber and the second chamber, and the pouring hole communicates with the first chamber; the first partitioning member is arranged in the passage, and the first partitioning member can partition the passage, and melts when the metal solution is poured to a preset height of the second chamber, so that the first chamber and the second chamber are communicated. In the application, the cavity of the cup body is separated into the first chamber and the second chamber by the partition, the passage is opened after the first partitioning member melts under heat, the metal solution separated from impurities flows into the first chamber through the passage, and finally enters the sprue through the pouring hole, so that the impurity layer is not disturbed by the high-speed flowing metal liquid, the impurities in the metal solution are reduced to enter the sprue, and the casting quality is improved.
