Technical Field

The utility model relates to a die casting die field, concretely relates to die casting die with S-shaped tangent line runner.

Background

The die casting die is a tool for casting metal parts, and the working principle of the die casting die is that alloy molten metal (zinc alloy, aluminum alloy and magnesium alloy) is injected into a die cavity of the die through a runner to form a die casting product, then the die casting product is subjected to demoulding to remove water gap waste to obtain a finished product, a main runner of the existing die casting die is directly communicated with the die cavity and lacks certain buffering, and the molten metal easily generates turbulence when reaching the joint of the main runner and the die cavity, so that the shape of the joint of the formed die casting product and the water gap waste of the runner is complex and thick, the water gap cannot be removed quickly in subsequent working procedures, and if the force of an operator is too large, the product is also easily deformed.
