Abstract

PURPOSE:To obstruct a casting metal from being chilled, and also, to use the titled metallic mold many times, by dispersing and burying a ceramic pin on the inside surface of the metallic mold so that its top surface coincides roughly to the inside surface of the metallic mold. CONSTITUTION:In a necessary area of the inside surface of a metallic mold 10, a ceramic pin 20 consisting of a ZrO2 compound, etc., is dispersed and buried roughly equally so that the end face of its top part coincides roughly with the inside surface of the metallic mold 10. Said ceramic pin 20 is buried by fitting and fixing it firmly by shrinkage fitting, etc., to a pin hole 11 which has been pierced by machining on the inside surface of said mold 10. Also, it is desirable that an area rate by which the inside surface of the mold is occupied by the end face of its top part is large such as about >=40%. As for this ceramic pin 20, its heat insulating property is satisfactory, and it is obstructed effectively that a casting metal is chilled, by controlling a cooling and coagulating speed of the casting metal. Also, the ceramic pin 20 is excellent in its heat resistance, and heat-resisting and mechanical shock property, endurable against the continuous repeated use of many times, and also, deterioration of casting due to a melt loss, peeling, etc., does not occur either.
