Structure characteristics and forming process of drive end cover were analyzed. Combining with manufacturing process of mould

multi-step parting face was determined as the main parting face of the mould

and angle pin location was adopted to make mould structure compact. Hydraulic drawing-core mechanism was adopted for two-side of inner-sinking in the die casting die

and pre-resetting mechanism was set to avoid the interference of core slide with ejector pin. Eccentric slitting runner was designed in gating system

in which runner and ingate were set on left and right slide

respectively

taking the desirable filling and exhaust during die casting process

effectively improving the quality and qualified rate of the drive end cover.
