INJECTION VALVE, ESPECIALLY FOR A MOULD FOR AN OPTICAL LENS

摘要

The invention relates to an injection valve comprising an injection channel (17) that opens outwards via an outlet (18) and has a specific inlet for the arrival of the moulding material (19A) remote from said outlet (18), in addition to a slider unit (20) that is moveably mounted in the injection channel (17) and controls the outlet thereof (18). According to the invention, the injection channel (17) has a specific outlet (19B) for discharging the moulding material. The invention can be used to mould an optical lens made from a polymerizable synthetic material.
