Considering the structural features

through analyzing the forming process and combining with the die casting machine from the enterprise and technological parameters

die casting die was designed.The parting face of the mould was set at the longitudinal maximum section.Due to requiring large pulling-core distance at side-hole of the tube joint

two-directional pulling-core mechanism with side-core slanted guide pillar was designed.Through designing ring-gate in gating system

smooth filling could be realized as a result of avoiding the molten metal directly impacting core

improving the inner and surface quality of the die castings.Push-put mechanism was set at ring-gate location and overflow slot location

improving greatly the surface quality of the tube joint.
