Abstract

A gating system of eagle beak feeder and 4-subzone venting has been adopted for die-casting die design based on the structural features of the aluminum alloy lower cylinder of a new type of automobile engine

solving problems such as difficult parts forming

prominent air entrapment and poor quality of internal porosity.The installation mode of 5 cast iron inserts and the preheating temperature of 230℃ were designed to solve the positioning and separation problems of inserts installation.Some measures

including the long mold core for in-material alignment made from YXR33/W360 high-tenacity material

Dura-AR surface plasma treatment and increased high-pressure spot supercooling

were adopted to avoid the thrust and burn of the mold core.Extrusion pin was designed at high-pressure oil passage hole and the extrusion cylinder was designed with cooling plate to solve the problem of shrinkage cavity and ensure continuous production.
