LAMP APPLIANCE FOR CAR, AND METHOD AND MOLD FOR MOLDING LAMP BODY MADE OF SYNTHETIC RESIN OF LAMP APPLIANCE FOR CAR

摘要

PURPOSE: To inexpensively produce a lamp body made of a synthetic resin without providing a slide core, an angular pin or a pocket hole to a mold by dividing a mold part molding a lid member into a block positioned on the side of a surface having a recessed stripe and a block positioned on the side of a surface having no recessed stripe. CONSTITUTION: When a lid member is separated from the part 38 positioned on the opposite side of the slide mold 29 of a movable mold 21, the shoulder part 35 of the slide mold 29 comes into contact with the rear opening edge of the slide hole 30 of the movable mold 21 to become a state not moving more forward. Ejection pins 28, 28 are further thrust out therefrom and a lamp body 2 is moved so as to separate from the slide mold 29. Since the part 38 of the movable mold 21 is not positioned on the opposite side of the slide mold 29 of the lid member 13 at this point of time, the lid member 13 is bent at a hinge part 14 and separated from the slide mold 29 while bent toward the direction separating from the slide mold 29. By this constitution, the molded lamp body 2 is released.
