Abstract

PROBLEM TO BE SOLVED: To bring a slide pin into contact with a protrusion and inject into a core mold to carry out the molding, rotate a core mold plate, move a molded product to a forming position, move the slide pin and inject resin into a cavity to carry out the forming and bond integrally a lens holder with an illuminant holder. SOLUTION: A fitting section A of a molded product 11 is molded by a protrusion 14a, and a step D is molded by a pin 16. Then, a mold is opened and a core template 13 is rotated by 180 deg., and the molded product 11 is carried to the forming side. In the process, the slide pin 16 is moved by the distance (x), and the step D section of the fitting section A is in the state of being formed in the molded product 11. Black resin is fed from a secondary nozzle N2, passed through a secondary runner R2 and a secondary pin gate G2 and injected into a secondary cavity 14B and formed. Thus the mold is opened, and a final molded product composed of the molded product 11 (lens holder) integrated with the formed product (illuminant holder) 12 is released.
