Lock device for use in mold to fabricate bimaterial plastic pieces, has actuators coupled with actuating mechanism, where inoperative spaces occupied by mechanism are reduced to permit movement of actuators

摘要

The device has actuators (2) actuated by hydraulic systems to limit passage of materials in a space (3) inside a mold (1), where the materials form an injected piece by injection points (4, 5) provided in the mold. The actuators are coupled with an actuating mechanism (6). The actuating mechanism comprises a transversal support (8) actuated by a single hydraulic cylinder (12). Inoperative spaces of the mold occupied by the actuating mechanism are reduced to permit movement of the actuators.
