Abstract
PURPOSE: To obtain the titled mold which is not distorted even when applied with a high differential pressure at the time of molding and does not produce a flash line on the surface of a molded article, by a method wherein female and male molds are divided so that they can be mill-finished, and they are connected together by specified manner.
CONSTITUTION: A plurality of partial molds 11, 12 for the feame mold divided at a surface perpendicular to the mold releasing direction A for each depth D1, D2 such as to enable milling are provided, and a plurality of partial molds 21, 22 for the male mold dvidided for each depth d1, d2 such as to enable milling are provided. A groove 5 is provided along the mating edges of the molds 11, 12, and the surface of each partial mold 11, 12, 21, 22 is milled with finishing allowances 71, 72 being left. The molds 11, 12 are connected to each other after positioning with an annular cotter 31 and a groove 32, then a boss-shaped cotter 41 is fitted into a hole 42 and the molds 21, 22 are fastened together by bolts 6. Further, welding W is conducted so as to fill the groove 5, and the surface of the welded bead is finished by milling it together with the allowances 71, 72.
