Aiming at the features of cylinder castings which exist flange around the cylinder parts and rectangle or arc grooves in the inner wall as well as flange on the ends of rectangle grooves

the die casting die with twice cavity parting for snapping slag in the gate and inside core-pulling by angle slides was designed. The die adopts gating system with ring gate

limit-distance mechanism

twice cavity parting to snap slag mechanism and inside core-pulling mechanism. The slag was automatically snapped by open force in cavity parting

and inside core-pulling by angle slides was realized in the ejection

so the problems were solved during the inside core-pulling

ejection and snapping. The mould exhibits compact in structure

convenient in operation and excellent in filling

realizing the smooth ejection and meeting the requirements.
