METHOD FOR INJECTION MOULDING OF PLASTIC-MATERIAL LENTICULAR BODIES FOR LIGHTS OF MOTOR VEHICLES AND SIMILAR, AND LENTICULAR BODY FOR LIGHTS OF MOTOR VEHICLES AND SIMILAR

摘要

A method for injection moulding of plastic-material lenticular bodies for lights; of motor vehicles and similar, the method comprising the steps of coupling a punch half-mould with a first matrix half-mould so as to define, on the surface of the punch half-mould, a first closed cavity that copies in reverse the shape of the first plastic-material sheet; filling said first cavity with a first plastic polymer in a liquid state, injecting the first plastic polymer in the first cavity from an injection point located at said first segment of the peripheral edge of the first plastic-material sheet; and finally separating, after the first plastic polymer has solidified to form the first plastic-material sheet, the punch half-mould (15) from the first; matrix half-mould maintaining the first plastic-material sheet still on the surface of the punch half-mould.
