The location of the ingate of die casting mold making should be determined according to the structure of the die casting, the change of the wall thickness, the shrinkage deformation, and the mold parting position.
The ingate position should be the shortest distance between the metal liquid filled cavity, to prevent the loss of excessive heat of the metal liquid and produce cold shut or stripe and other defects when filling.
Metal liquid should be first filled with the deep part of the cavity, to avoid the flow of the metal liquid into the parting surface leading to the closure of the exhaust groove.
As far as possible the use of single ingate design, to prevent the flow of multi-strand liquid metal produce the defects such as vortex and air entrapment when it into the cavity.
The general structure of the die casting mold making is mainly the thick ingate, so that the liquid metal filling is stationary. This is conducive to the exhaust and transfer of static pressure.
The position of the ingate is located in the mechanical process position, avoiding the position of high precision, high surface roughness and non machining, to prevent leaving traces after removal of the ingate.
