Title:
半凝固鉄系合金の成形用金型
Document Type and Number:
Japanese Patent JP4574065
Kind Code:
B2
Abstract:
An injection mold for casting a semi-solidified Fe alloy includes a scalping gate for eliminating surface oxide film of a semi-solidified Fe alloy injected into the mold cavity from a pressure chamber. The scalping gate is arranged between the pressure chamber and a runner that is in communication with the mold cavity. The mold halves and the scalping gate are each formed of a copper alloy having a thermal conductivity of not less than 120 W/(m.K) and a hardness of not less than 180 HB. The mold halves and the scalping gate each have a cermet layer consisting essentially of at least one member selected from a group consisting of Co, Cu, Cr and Ni. The cermet layer is formed by electro-spark deposition, via an intermediate layer of Ni alloy, which is also formed by electro-spark deposition.
