MOLD CLAMPING DEVICE FOR MOLDING MACHINE

摘要

PURPOSE:To open and close molds by rotating motion and to improve durability by constituting the mold opening/closing power transmission means of the mold clamping device of a crank toggle mechanism rotated by an electric servo motor and a double link toggle mechanism driven by a cross head at the front end of the crank toggle mechanism. CONSTITUTION:The cross head 27 connected to the front end of a connector rod 25 of the crank toggle mechanism A driven by receiving the rotation of the electric servo motor 8 is linearly driven by turning of the connector rod 25. The double toggle mechanism mechanism B shifts from a folded state (mold opening state) to an extended state (mold closing state as said rod turns. The toggle mechanism is reset from the extended state to the folded state by the reverse run of the servo motor 8.
