Abstract

PURPOSE:To inexpensively obtain the experimental die having a good surface state and no defects by casting Al, Zn and Cu low m.p. alloys with executing the cooling of a plaster mold and vacuum exhausting via a buried cooling pipe. CONSTITUTION:A cooling pipe 10 is mounted on a rubber mold 12 to form the plaster mold 14 in which a cooling pipe 12 is buried. This plaster mold 14 is then mounted on the vent plate 15 piercing a vent groove 17 on the surface, a cooling is executed by the cooling pipe 10 with exhausting and a low m.p. alloy is cast. The product of good surface quality having no defects is thus obtd. at low cost.
