3. Cast analysis 
Due to the filling Angle of the gate, the overall filling is not synchronized. As shown by the yellow arrow in the middle of Figure 5, the metal travels slowly, while the red arrow on the upper and lower sides travels fast. The metal flow first reaches the overflow port and is surrounded.
4. Improvement 
Adjust the filling Angle of the upper and lower gates, so that the three gates are synchronously filled into the deep cavity, the upper and lower sides are formed ends, and two slag bags and exhaust channels are added.

5. Tips
About filling energy loss:
In this case, the main runner is filled first, and after the main runner is filled, the gate is pressed into the side wall by pressure. At this time, the energy loss of the casting filling is already large. If the current alignment is rotated 90°, the energy loss from the bottom end face will be relatively small.
