Abstract

PURPOSE:To permit the easy adjustment of a cooling rate and to obtain a molding of a high level by providing respectively cooling mechanisms and heating mechanisms to both male and female dies and providing ceramic members to the suitable places of the molding parts. CONSTITUTION:Both male and female dies 1, 2 are formed of a heat resistant metal and cooling mechanisms 4 and heating mechanisms 5 are disposed in both dies 1, 2. The molding surfaces 1a, 2a are recessed to the mating surfaces of both dies 1, 2 and the ceramic members 3 are provided to the parts where the adjustment of the cooling speed for the surfaces 1a, 2a is particularly required. A molten metal (m) is poured into the molding part A while the molding part A is cooled and heated by the cooling and heating mechanism 4, 5 of both dies 1, 2. The male die 1 is thereafter clamped and while both dies 1, 2 are cooled, the temp. of te molten metal (m) is decreased down to the solidifying section, by which the molding is formed.
