Abstract

PURPOSE: A molding die of cylindrical parts being so constituted as to form cylindrical parts of different lengths simply by dismounting simple auxiliary parts without changing the basic construction of the die and which permits considerable saving of material costs and die costs.
CONSTITUTION: The projecting part 4 of a core 3 and a core auxiliary part 6 are inserted into the recess 2 of a cavity 1, and, for example, a resin is flowed between the two to form a busref duct 11 of a length l1 having a collar 11a at one end. Further, in the case of forming a long busref duct 11, the cavity auxiliary part 5 is removed from the recess 2 of the cavity 1, thence the core auxiliary part 6 is removed from the end of the projection 4 and in place a core auxiliary part 12 of a length l2 is mounted by a bolt 7. Next, if a resin is flowed between the cavity 1 and the core 3, the busref duct 11 of a length l3 may be formed. Since the plural through-holes 10, 13 of the core 3 may be connected through the through-holes 10, 13 provided to the parts 6, 12, the parts 6, 12 may be cooled by the coolig water flowed into the through-hole 9.
