PURPOSE: To cause a parting line not to deviate by a method in which the beads for parting line which project into the cavity at the mold surface of a mold for resin molding and define the boundary of coating, is provided, and masking is achieved along this beads for parting line.
CONSTITUTION: The beads for parting line project into the cavity 12 in the female mold 10 of molds. These beads for parting line constitute a part of a masking jig defining the parting line of coating, dividing a coating part from a noncoating part, and function as the guide for setting the masking jig. These beads 14 for parting are formed with the slope having a draft and height necessary for setting the masking jig 15 at the side of noncoating range at the boundary between a coating range and a noncoating range.
