ンスフア成形用金型。[Claims for Utility Model Registration] (1) Between the abutting surfaces of the upper and lower molds 1 and 3, there is a main runner part 7 extending from the cull reservoir 6 at the lower end of the pot 2, and a main runner part 7 along the longitudinal direction of the main runner part 7. A plurality of arranged cavities 8 and a branch runner part 9 connecting the main runner part 7 and the cavity 8 are formed, and the thermosetting resin stored in the pot 2 is forced into the cavity 8 and molded. In the transfer molding mold, the closer the branch runner section 9 is to the cull reservoir 6, the more the branch runner section 9 is inclined toward the main runner section 7.
A mold for transfer molding, characterized in that the mold is formed so that the number increases in a direction opposite to that of the transfer mold. (2) The transfer molding mold according to claim 1, wherein the branch runner portion 9 is formed to have a smaller cross-sectional area than the main runner portion 7.
