METAL MOLD FOR INJECTION MOLDING AND METHOD OF MANUFACTURING INJECTION MOLDED PART

摘要

An injection molded part (15) integrally formed by adhering a transfer layer (29) on the surface thereof, wherein the cross sectional shape of a top surface corner part at a position where the radius of curvature (r) is minimum can meet the requirements of top surface corner part radius of curvature R < distance D between top surface part and reference plane and 0.1 <= r x R x draft at parting corner part A/D <= 10, R >= D and 0.2 <= r x R/D <= 30, or 0.01 <= r x R x radius of curvature at parting corner part R2 x A/distance between top surface part of recessed part and reference plane H <= 1.0.
