4. Casting analysis
Due to the layout of the gating system, there is no overflow trough on the core pulling pillow position, being a forming dead corner. 
During die casting, the air in the mold cavity is squeezed in this area, forming defects such as cold lap and porosity under the compact layer of the product, resulting in peeling on sandblasting.
5.Improving measures
The exhaust channel is arranged on the core pulling pillow position, and the exhaust channel is diverted to the slag  through the  exhaust channel , so that the metal liquid flow uantity in the bad area can be increased. In order to effectively reduce the internal air residue of the product, improve the problem of sandblasting.
6. Tips
For pulling-core
same as parting surface,pulling-core could set channels to discharge air and slags accordingly.
