Abstract:
An injection molding die 1 is a die for a resin molding 20 that has an inner surface rib 27 and an inner surface recess 28 provided at the base end. The die 1 is provided with an outer mold 2 and a core 3. The core 3 comprises a main body-forming section 6a for forming the inner form of the resin molding, an outer surface recess 7 for forming the inner surface rib 27, and an outer surface rib 8 for forming the inner surface recess 28. The angle of inclination β between a base end direction extension line S of the outer surface of the main body-forming section and the base end portion of the outer surface rib 8 is greater than the angle of inclination α between said base end direction extension line S and the distal end portion of the outer surface recess 7, and the height H of the outer surface rib 8 is greater than the depth D of the outer surface recess 7.
