Mold clamping device

摘要

The mold clamping device is provided with a first platen to which a stationary mold is attached. A movable mold unit is capable of approaching and moving away from the stationary mold. A second platen is linked to the first platen via a tie bar. When the movable mold unit and the stationary mold are closed, a wedge member is driven onto the movable mold unit to generate mold clamping force. The second platen has a pressure receiving surface. The pressure receiving surface receives, through the wedge member, mold opening force that is generated by filling, with a molding material, the stationary mold and the movable mold unit that are in the closed state.

1. A mold clamping device comprising:
a first platen to which a stationary mold is attached; a movable mold, wherein the movable mold and the stationary mold are closed to form a cavity; a movable mold holding portion that is structured and arranged so as to be moved toward and away from the stationary mold together with the movable mold by a mold moving mechanism; a second platen linked to the first platen via a tie bar; and a wedge member that is structured and arranged to be driven onto a back of the movable mold holding portion to generate mold clamping force when the movable mold and the stationary mold are closed, wherein the second platen has a pressure receiving surface structured and arranged to receive through the wedge member, a mold opening force generated by filling the stationary mold and the movable mold that are in the closed state with a molding material.
