Requirements for mold sprue on cold chamber horizontal die casting machine

There are some requirements should be considered for the Cold Chamber Die Casting machine. Firsly, the size of the pressure chamber should be selected according to the required specific pressure and pressure chamber filling degree. At the same time, the inner diameter deviation of the gate sleeve should be appropriately magnified several threads than the deviation of the pressure chamber diameter, so as to avoid the problem of punch stuck or serious wear caused by the different coaxial gate sleeve and the pressure chamber diameter, and the wall thickness of the gate sleeve can not be too thin.  The length of the gate sleeve should generally be less than the discharge lead of the injection punch in order to release the paint from the pressure chamber.  Secondly, The inner hole of the pressure chamber and the gate sleeve should be finely ground after heat treatment, and then ground along the axis direction, with surface roughness ≤Ra0.2μm.  

Thirdly, for the cold chamber Die Casting, the shunt and the formation of the coating of the concave cavity, the depth of the concave is equal to the depth of the sprue, the diameter of the gate sleeve diameter, along the demoulding direction has 5 degrees of slope.  The filling degree of the chamber can be increased because the volume of the effective length of the chamber is shortened when the sprue is used.
