PUMP MEMBER FOR DIE CASTING AND PRODUCTION THEREOF

摘要

PURPOSE:To provide a pump member for die casting and a manufacturing method thereof which does not break by thermal stress at the time of internal chill does not develop fatigue breakage at the time of injecting and is not eroded by molten aluminum and can absorb thermal impact and the thermal stress acted to the insert member and prevent the erosion of a heat resistant cast iron member. CONSTITUTION:In pump member for die casting constituted with tubular insert members 7A, 10A as a passage for molten metal in the inner hole and the heat resistant cast iron members 7B, 10B casting-in the insert members, the insert member is composed of carbon fiber reinforced carbon material reinforced with the carbon fiber 16. The carbon fiber reinforced carbon material is constituted with carbon fiber spun yarn texture 200 as base material.
