How much do you know about the gate knowledge of die casting? Let's follow the editor of Die casting processing in china for a brief understanding!
1. After the molten metal enters the mold, the parting surface should not be closed immediately, and the overflow groove and the exhaust groove should not impact the mold core directly. The flow direction of the molten metal after entering the mold is as far as possible along the cast ribs and heat sinks, filling from the thick wall to the thin wall, etc.

2. When selecting the position of the inner gate, make the flow of the molten metal as short as possible. When using multi-strand inner gates, it is necessary to prevent several strands of molten metal from converging and impacting each other after molding, resulting in defects such as eddy current slug and oxidation inclusions.
3. The thickness of the inner gate of the thin-walled part should be appropriately smaller to ensure the necessary filling speed, and the setting of the inner gate should be easy to remove, and the casting body should not be damaged.
The above is what Die casting processing in china tells: a brief introduction to the knowledge of the inner gate of die casting.
